The present invention relates to a cooking system; more particularly, the present invention relates to a cooking system for cooking.

Background

The cooking is a process of frying cooking materials in a pot, and is mainly characterized in that the quick frying of the hot pot is required, so that the cooking materials are quickly and uniformly heated, and the effects of crispness, tenderness, freshness and fragrance are achieved. Currently, automatic/semi-automatic cooking systems have been developed that can replace or reduce manual operations and have a cooking function.

The pan body in the cooking device has two degrees of freedom, and can respectively realize rotation and turnover, thereby achieving the purposes of automatic stir-frying and automatic dish discharging.

Chinese patent application 201210575195.3 discloses a bidirectional automatic stir-frying pan, which comprises a pan body, a pan cover, a variable frequency motor, an inner rotating shaft, a supporting seat, a stir-frying fork, an outer rotating shaft, stir-frying blades and a switch. Wherein, the pan body and the pan cover form a horizontally arranged cylinder; the variable frequency motor is provided with a high gear button, a low gear button and a medium gear button and drives the rotating shaft to rotate; the rotating shaft is horizontally arranged at the center of the pot body and is supported at two ends by the supporting seat; the supporting seat supports the pot body, the rotating shaft and the heating device; the stir-frying fork is perpendicular to the rotating shaft and is arranged in the center of the pot body, and the end part of the stir-frying fork is provided with fork teeth with different sizes; the upper end part of the stir-frying blade is square; the switch is arranged on the pot body to adjust the working state of the pot body. After the dishes enter the pot body, the stir-frying blades and the stir-frying fork are respectively driven by the motor to do 360-degree circular motion, the dishes are continuously overturned in the pot body to be processed, the stir-frying frequency is adjusted by adjusting the frequency of the motor, and finally the processing of the dishes is finished.

In the process of cooking by using the above cooking apparatus, as shown in fig. 12, although the pot body 30 rotates to drive the cooking materials 30' to turn over in the pot, the cooking materials are still basically distributed in a stacked manner at the bottom of the pot body, only a small part of the cooking materials are in direct contact with the pot body, and the contact area between the cooking materials and the pot body is less than 40% of the surface area of the inner wall of the pot body, so that the cooking materials can only be heated in a stacked manner, and meanwhile, the cooking materials and the pot body are only in contact with each other with small acting force, the thermal resistance is large, and the heat is difficult to be conducted to the cooking materials far away from the inner wall of the pot body, so that the cooking materials are heated. Although the stirring mechanism is used for stirring the cooking materials to increase the contact probability between the materials at different positions in the pot and the pot body and between the surfaces of the materials, the stirring mechanism cannot eliminate the accumulation state of the materials, and is difficult to stir the core part of the accumulated materials, so that the defects of uneven heating and low heating efficiency of the cooking materials cannot be effectively overcome. In addition, the cooking materials are subjected to a large external extrusion force by using the stirring mechanism, so that the completeness of the shape of the raw materials is difficult to keep, and the requirement of the Chinese dishes on the shape cannot be met. In addition, in order to meet the requirement of quick frying of a hot pot, the pot body of the cooking equipment is required to be designed to be larger so as to increase the contact area between cooking materials and the pot body and improve the heating efficiency, and the cooking equipment has the defect of large volume. Otherwise, in order to ensure the quality and taste of the cooked dishes, the cooking machine can only cook less cooking materials each time.

Disclosure of Invention

Aiming at the defects of the prior art, the invention aims to provide a cooking system which can promote cooking materials to be uniformly distributed in the longitudinal direction and the circumferential direction of a pot body and is convenient for quickly and uniformly heating the cooking materials.

In order to achieve the above object, the present invention provides a cooking system comprising: a barrel pan for containing cooking materials; the rotary driving device is connected with the pot body and is used for driving the pot body to rotate around the rotary axis of the pot body. Wherein, the internal force applying mechanism that can drive the cooking material and rotate and rise along with the pot body that is provided with of pot, this force applying mechanism include with the cooperation of pot body inner wall and extend in succession or discontinuously between two vertical tip of pot body to a plurality of force applying parts that provide holding power to the cooking material, these a plurality of force applying parts have roughly even distribution in the circumference of pot body. Wherein, the cooking system further comprises a controller which controls the pan body to rotate according to the rotating speed control instruction.

In the present invention, the rotation axis of the pot body means a connecting line passing through approximately the geometric center of the inner periphery of each cross section of the pot body. The inner circumference of the cross section of the pot body is usually formed into a circle or a polygon, and when the inner circumference of the cross section of the pot body is circular, the geometric center of the inner circumference is the circle center; when the inner circumference of the cross section of the pot body is a regular polygon, the geometric center is the center of an inscribed circle or an circumscribed circle.

In the present invention, the controller may be a microprocessor, a control circuit board, a control program, or a combination thereof. The rotational speed control command may be output by a cooking program or set by other means. For example, input may be via an input device of the cooking system. In the present invention, the cooking program may be stored in the controller or a storage device of the cooking system, or may be input from the outside of the cooking system. For example, the cooking program is stored in a cloud server, and the cooking system calls the cooking program from the cloud server when in operation.

In the cooking system, the force applying members are approximately uniformly distributed in the circumferential direction of the pot body, and each force applying member continuously or discontinuously extends between the two longitudinal end parts of the pot body, so that the cooking materials are uniformly distributed in the circumferential direction and the longitudinal direction of the pot body under the combined action of the pot body and the force applying members, the cooking materials are in a dispersed state in the pot body, and a foundation is laid for realizing the rapid and uniform heating of the cooking materials.

In one embodiment of the invention, the number of force-exerting elements is 2-9, which has the advantage that the force-exerting elements can better bring the cooking material up with the rotation of the pot and give a more even distribution of the cooking material over the circumference of the pot, which is particularly advantageous for granular cooking material.

In another embodiment of the present invention, the height of the force applying member is 0.5 cm to 5 cm, preferably 1 cm to 3 cm, so that the cooking material has a proper thickness on the inner wall of the pot body.

In the invention, the force application member can be fixedly arranged on the inner wall of the pot body. For example, the force applying member may comprise a ridge or rib formed on the inner wall of the pot body, the ridge or rib may extend continuously between the two longitudinal ends of the pot body, or may be formed by combining a set of columnar protrusions arranged at intervals in the longitudinal direction of the pot body.

In the invention, the force application mechanism can also be arranged in a manner of relative rotation with the pot body. The force application mechanism can comprise a rotating shaft and one or more force application members fixedly connected with the rotating shaft, the rotating shaft and the pot body can be arranged in a relatively rotating mode, and the gap between the force application members and the inner wall of the pot body can be 0.1-5.0 mm, preferably 0.1-3.0 mm, and more preferably 0.1-1.0 mm. Preferably, the surface of the force application member contacting or approaching the inner wall of the pot body is an elastic surface to prevent the mechanical part from being locked. For example, the force applying member may be a steel member with a teflon attached surface layer.

The technical scheme has the advantages that when the force application mechanism and the pot body rotate synchronously, the force application member provides supporting force for cooking materials and drives the cooking materials to rotate and rise along with the pot body by matching with centrifugal force; when the force applying mechanism and the pan body rotate relatively, the force applying mechanism can stir and fry the cooking materials and remove the cooking materials which are possibly adhered to the inner wall of the pan body.

According to an embodiment of the present invention, the cooking system controls the pot to rotate at a first rotation speed greater than or equal to a critical rotation speed (here, an angular speed) in a first mode according to the rotation speed control command, so that the cooking material is attached to the pot and performs a rotational motion with the pot. Wherein, the critical rotating speed is the lowest rotating speed which can lead the cooking materials to be attached on the pot body and to do circular motion along with the pot body.

In the present invention, the first mode is also called a pan sticking heating mode, which means that most of the cooking materials are attached to the pan body and rotate synchronously with the pan body in the first mode. In practice, it is preferred that in the first mode substantially all of the cooking material is in a state of attachment to and synchronous rotation with the pot. In the present invention, the cooking materials attached to the pot body does not mean that all the cooking materials attached to the pot body are in direct contact with the pot body, but means that the cooking materials form a cooking material layer with a certain thickness on the inner wall of the pot body, wherein only the cooking materials located outside the cooking material layer are in direct contact with the pot body.

In the invention, the first rotating speed of the pan body in the first mode can be a constant value, and can also be a changing value which is changed in stages or continuously, as long as the first rotating speed is not lower than the critical rotating speed. It should be noted that the critical speed is not a fixed value, but varies depending on the inner diameter of the pot, the angle of inclination of the axis of rotation of the pot, the nature (e.g. viscosity, shape) of the cooking mass, the amount of cooking mass, etc. An obvious example is that the critical speed is higher when more cooking material is present than when less cooking material is present, since the radius of rotation of the cooking material far from the inner wall of the pot is smaller than the radius of rotation of the cooking material near the inner wall of the pot, so that to rotate the cooking material far from the inner wall of the pot synchronously with the pot it is necessary to have a higher speed of rotation than the cooking material near the inner wall of the pot in order to provide a greater centrifugal force. In order to achieve better heating and cooking, it is preferable to have most of the cooking materials including the cooking materials far from the inner wall of the pot body, and more preferable to have almost all of the cooking materials in a state of being attached to the pot body and rotating synchronously with the pot body, so that the critical speed is higher when the cooking materials are more than when the cooking materials are less.

In the above technical solutions, on one hand, the pot body rotates at a first rotation speed not lower than the critical rotation speed in a first mode, so that most or even almost all cooking materials can be attached to almost the whole inner wall of the pot body in a relatively uniform thickness and synchronously rotate along with the pot body, the coverage area of the pot body can reach 90% or more of the total surface area of the inner wall of the pot body, the surface area of the pot body is fully utilized, the cooking materials are in a distributed heating state, and the heating and cooking efficiency can be improved; on the other hand, the surface area of the pot body is effectively utilized, so that the cooking system has larger cooking capacity than that of the existing cooking equipment, and under the condition of keeping the volume of the pot body unchanged, the cooking capacity can reach 2 to 3 times of that of the existing cooking equipment, so that the cooking system is very suitable for producing dishes in large scale and is particularly suitable for high-peak dining occasions such as dining halls, restaurants and the like.

Wherein, preferably, under the first mode, the controller firstly controls the pot body to rotate at a rotating speed which is equal to or slightly greater than the critical rotating speed, so that the cooking materials are basically uniformly distributed on the inner wall of the pot body, and then the rotating speed of the pot body is increased to a higher value, so as to further increase the contact force between the cooking materials and the inner wall of the pot body, so that the cooking materials and between the cooking materials and the pot body are more closely attached, thereby further reducing the thermal resistance, improving the heating efficiency and enabling the cooking materials to be heated more uniformly. For example, the pot body is first controlled to rotate at a critical rotation speed of about 1.0 to 1.1 times or 1.0 to 1.3 times for a predetermined time, and then the rotation speed of the pot body is raised to the critical rotation speed of 1.3 to 2.0 times or 1.5 to 2.0 times.

According to another embodiment of the invention, the cooking system controls the pot body to rotate at a second rotation speed less than the critical rotation speed in the second mode according to the rotation speed control instruction, so that the cooking material is driven by the pot body to rotate and rise and then fall. The second mode may also be referred to as a stir-fry mode or a mix mode, which refers to a mode in which the cooking ingredients are being stir-fried or mixed. In the present invention, the second rotation speed may be a constant value, or may be a variable value that changes in stages or continuously. For example, the second rotational speed may be 0.6 to 0.95 times, 0.7 to 0.95 times, or 0.8 to 0.95 times the critical rotational speed. Wherein, the larger the value of the second rotating speed is, the higher the falling position of the cooking materials is, and the better the stir-frying or mixing effect is.

Specifically, it is preferable that the cooking materials are controlled to fall substantially with the rotation of the pot body within a range of 90 degrees to 180 degrees, and more preferable that the cooking materials are controlled to fall substantially with the rotation of the pot body within a range of 135 degrees to 180 degrees. In the invention, the rotation angle of the cooking materials adopts the following angle coordinates: the geometric center of the inner periphery of the cross section of the pot body is taken as a coordinate center, the lowest point of the rotating track of the pot body is taken as a zero point, and the rotating direction of the pot body is taken as a positive direction.

It should be noted that the centrifugal forces to which the cooking materials are subjected are different at different distances from the inner wall of the pot, and therefore the cooking materials having different distances from the inner wall of the pot usually have different falling angles. For example, cooking materials near the inner wall of the pan body typically have a greater angle of fall than cooking materials away from the inner wall of the pan body. That is, the falling of the cooking mass occurs within a certain angular range, and not only at a certain determined angular position. And, because the cooking materials after falling can rotate and rise again under the drive of the pan body, the falling of the cooking materials is a circulating and continuous process.

Above technical scheme's advantage lies in, stir-fry in-process cooking material has parabola shape's whereabouts orbit under the inertia effect, and the whereabouts time is long, and the most cooking material after the whereabouts can be attached to the pot body once more in great scope to rotatory rising under the pot body drive, rather than piling up on the cooking material of pot body bottom, therefore still have great area of contact and longer contact time between cooking material and the pot body inner wall, make the cooking material still can be heated comparatively fast this moment, evenly. In addition, the technical proposal has the advantages that the cooking materials are fried or mixed fully, the cooking materials are less affected by the external force of extrusion in the frying or mixing process, and the shape of the raw materials is easy to keep complete, thereby achieving the cooking effect with good color, fragrance, taste and shape.

In the invention, the rotating speed of the pot body during feeding is not required, and the feeding can be carried out when the pot body is in a static state or rotates at any rotating speed. Wherein the dosing is preferably performed in the second mode such that the pot contents are first stir-fried or mixed. For some viscous materials, such as sized meat, feeding in the second mode may solve or reduce the problem of material agglomeration because the viscous material is sufficiently broken up during the stir-fry process after entering the pan while the surface is heated and cooked so that its viscosity is reduced and it cannot or is not easily agglomerated. In addition, since the cooking materials are usually fed into the pot body for a plurality of times or in a plurality of batches, the feeding in the second mode can ensure that the cooking materials are mixed uniformly, and the cooked dishes are more tasty.

In the cooking system of the present invention, it is preferable that the rotation axis of the pot body is substantially horizontal in the first mode. This has the advantage that, on the one hand, the cooking product can be distributed uniformly over almost the entire inner wall of the pan body quickly and easily; on the other hand, the cooking materials are basically kept in a relative static state with the pot body after being attached to the pot body, so that the heating and cooking processes are conveniently controlled. On the other hand, if the rotation axis of the control pot is substantially vertical, the cooking material must be moved upward relative to the pot while rotating with the pot in order to be uniformly distributed over almost the entire inner wall of the pot, which is difficult to achieve, requires a more complex structure of the inner wall of the pot, and is difficult to control the heating and cooking processes.

According to another preferred embodiment of the present invention, in the second mode, the included angle between the rotation axis of the pot body and the horizontal plane is more than 0 degree and less than 20 degrees, and the pot body is inclined in a state that the pot opening is upward. Wherein, more preferably, the included angle between the rotation axis of the pan body and the horizontal plane is more than 0 degree and less than 15 degrees, and more preferably more than 0 degree and less than 10 degrees. During the process of stir-frying or mixing the cooking materials, if the pot body is in a horizontal state, since the cooking materials may collide with each other during the falling process, a small portion of the cooking materials may move toward the pot opening and fall out of the pot body, which not only causes waste of the materials but also causes frequent cleaning. At the moment, the pan body is controlled to be in an upward tilting state, so that the problem of material overflow in the stir-frying process can be effectively reduced or prevented. However, the tilt angle of the pan body should not be too large, otherwise the cooking materials will be excessively accumulated at the rear part of the pan body, the stir-frying effect is reduced, and the surface area of the front part of the pan body is difficult to be effectively utilized. In addition, the cooking materials are usually put in the position close to the pot opening of the pot body, and the pot body is controlled to have a proper upward inclination angle in the second mode, so that the cooking materials put in the pot body can properly move towards the rear part of the pot body, the cooking materials are prevented from being accumulated at the front part of the pot body, and the cooking capacity is improved.

In the invention, the inner circumferential surface of the pot body close to the pot opening can be formed into an inclined surface, and the inclined surface inclines towards the rotating axis of the pot body in the direction from the inner part of the pot body to the pot opening. The inclined surface may be a tapered inclined surface or an arc inclined surface. As described above, in the process of stir-frying or mixing the cooking materials, a problem that the cooking materials fall to the outside of the pot body may occur, and although the problem may be prevented or reduced by making the pot body have a certain tilt angle, the tilt of the pot body may cause the cooking materials to be excessively gathered at the rear portion of the pot body, and may cause different distances between different portions of the pot body in the longitudinal direction thereof and the heating device, so that the pot body is heated unevenly in the longitudinal direction thereof, and the cooking materials are heated unevenly. In the invention, the inner circumferential surface of the pot body close to the pot opening is formed into an inclined surface which can prevent or reduce the overflow of cooking materials, so that the pot body has a smaller upward inclination angle, even is in a horizontal state to stir or mix the cooking materials, and the longitudinal distribution and heating of the cooking materials in the pot body are more uniform.

In the present invention, the inner circumferential surface of the pot body at the end opposite to the pot opening may be formed as an inclined surface inclined toward the rotational axis of the pot body in the direction from the pot opening toward the inside of the pot body. The inclined surface may be a tapered inclined surface or an arc inclined surface. As previously mentioned, since the pan body is generally inclined upward during the feeding and stir-frying process, the thickness of the cooking material located at the rear of the pan body is generally greater than the thickness of the cooking material located at the front of the pan body, even after the cooking material is attached to the pan body. In the invention, the inner circumferential surface of the pot body at the end opposite to the pot opening is formed into the inclined surface, which can reduce the thickness of materials positioned at the rear part of the pot body, so that the cooking materials are more uniformly distributed in the longitudinal direction of the pot body, and the heating is more uniform.

In the invention, the pot body can be heated by utilizing an indirect heating device. The indirect heating device is usually an electromagnetic heating device or a combustion heating device, and the heating devices usually have higher heating power and can well meet the requirement of quickly frying the hot pot. In cooking with the cooking system of the invention, since the cooking material can be distributed over almost the entire longitudinal length of the pot, it is preferred that the indirect heating means is configured to heat at least half of the outer circumferential surface of the pot in the longitudinal direction of the pot, so that the cooking material is heated more uniformly in the longitudinal direction of the pot.

In the present invention, the cooking material may be directly heated by a direct heating device. The direct heating device can be a radiation heating device such as infrared or light wave, a hot air heating device or a superheated steam heating device. The advantage of cooking with a direct heating device is that it allows for rapid ripening of the surface of the cooking material to lock up moisture and other nutrients within the material, thereby improving the quality and mouthfeel of the dish.

Generally, it is preferred to cook using a combination of indirect heating means that heat (in most cases throughout) most of the time during a single cooking cycle, providing most of the heat for the cooking cycle, and direct heating means that provide less of the heat during a single cooking cycle (in most cases during the initial phase of cooking, allowing the surface of the cooking material to mature rapidly to retain moisture and other nutrients within the material). That is, in both the first mode and the second mode, it is possible for both the indirect heating means and the direct heating means to be in a heating state simultaneously or separately.

In a preferred embodiment of the present invention, the pot body is heated from the outside of the pot body by a combustion or electromagnetic heating means, and hot air is injected into the pot body by a hot air heating means to directly heat the cooking materials. Wherein, the temperature of hot air of the hot air heating device is preferably controlled to be 100 ℃ to 400 ℃, more preferably to be 200 ℃ to 300 ℃ so as to achieve better heating and cooking effects.

The direct heating of the cooking materials by hot air has the following advantages: firstly, the hot air can quickly make the surface of the cooking material reach a certain maturity degree so as to lock the water and other nutrient components in the material, thereby improving the quality and taste of the dish; secondly, the hot air can quickly take away the water vapor evaporated from the cooking materials so as to control the inside of the pot body to have proper humidity and achieve better cooking effect; finally, hot air heating also improves heating and cooking efficiency.

In the 201420058033.7 patent, although the double heat sources including the hot air heating device are used for heating, because the cooking materials are distributed in the pot body in a stacking manner, the contact area between the hot air and the cooking materials is small, and basically only the surface of the stacked materials can be heated, and the heating effect which can be actually achieved still needs to be improved. In the invention, because the cooking materials can be uniformly distributed on the inner wall of the pot body, the heating of the hot air on the inner wall of the pot body is reduced, the contact area between the hot air and the cooking materials is greatly increased, and the heating and cooking effects are further obviously improved.

In addition, the present inventors have unexpectedly found that dishes (such as shredded potatoes) cooked by the cooking system of the present invention having a dual heat source have a pleasant flavor and a sweeter taste, probably due to the better heating effect of the cooking system of the present invention, which can promote the maillard effect in the cooking material, and the generation of a sugar substance and a gas substance having a specific flavor. The cooking with the double heat source cooking device of the' 201420058033.7 patent may be caused by the poor heating effect of the hot wind, and the unexpected cooking effect is not found.

According to another embodiment of the invention, a semi-sealing device for blocking hot air from leaking out of the interior of the pot body is arranged at the pot opening position of the pot body, so that the pressure in the pot body is higher than the pressure of the external environment. The semi-sealing device is not used for completely sealing the pot opening of the pot body, but can prevent hot air sprayed into the pot body from rapidly leaking out, so that the inside of the pot body is in a relatively sealed state and positive pressure is formed in the hot air heating process. Therefore, hot air can fully enter gaps among cooking materials, the contact area between the hot air and the cooking materials is increased, heat loss in the cooking process is reduced, heating and cooking efficiency is improved, and water vapor and oil smoke in the pot body can be timely discharged and/or evaporated. For example, an openable pot cover is arranged at the pot opening of the pot body, and the pot cover can block hot air from leaking from the inside of the pot body in a closed state so as to relatively seal the pot body.

In the present invention, it is preferable that the pot cover is formed with an inclined surface on a side thereof facing the pot opening to be fitted with the pot opening, the inclined surface being inclined toward the rotational axis of the pot body in a direction from the pot opening toward the pot cover. The inclined surface may be a tapered inclined surface or an arc inclined surface. This has the advantage that during cooking, even though the cooking material may fall towards the pot opening, it falls onto the inclined surface and slides into the pot body again under the guidance of the inclined surface.

In the invention, the pot cover can be provided with the air supply outlet connected with the hot air heating device, and hot air is sprayed into the pot body through the air supply outlet, so that the structural design of the system is simplified. In consideration of the upward flowing characteristic of the hot wind, it is preferable that the air supply opening is provided at the pot cover near the lower portion thereof so that the hot wind has a longer flow path inside the pot body to maintain a longer contact time with the cooking materials. Furthermore, an air outlet can be arranged on the cooker cover, so that the cooker cover and the cooker body can be kept sealed as much as possible, water vapor and oil smoke in the cooker body are basically discharged to a subsequent treatment device through the air outlet, the cooking environment is purified, and the heat of the water vapor and the oil smoke can be recycled. Preferably, the caliber of the air outlet is adjustable, so that the internal pressure of the pot body can be controlled by adjusting the caliber of the air outlet.

In another embodiment of the invention, the pot cover is also provided with a feed hopper which can be opened and closed, so that not only is the cooking materials fed into the pot body convenient, but also the pot body can be kept in a relatively sealed state all the time in the cooking process. In the invention, a manual feeding mode can be adopted, and an automatic feeding device can be used for automatic feeding.

In another embodiment of the present invention, the cooking system further comprises a humidity sensor for detecting humidity in the pot, and the controller controls or adjusts the air volume, the air pressure and/or the air speed of the hot air heating device according to a comparison result between the measured humidity and humidity set by the cooking program. Preferably, the cooking system further comprises a temperature sensor for detecting the temperature in the pot body, and the controller controls or adjusts the hot air temperature of the hot air heating device and/or the heating intensity of the combustion or electromagnetic heating device according to the result of comparing the measured temperature with the temperature set by the cooking program.

During cooking, a certain amount of water vapor is mostly evaporated from cooking materials, and when the humidity in the pot body is too high due to the amount of the water vapor, the cooking effect is reduced. Therefore, it is required to rapidly discharge the moisture to reduce the humidity in the pot body to a proper range. In the 201420058033.7 patent, the air volume, air pressure and/or air speed of the hot air heating device are controlled or adjusted by the cooking program, but because the cooking program is preset, the environmental state in the pot body varies greatly in the actual cooking process, for example, when the quantity and/or characteristics of the cooking materials are different, the cooking environment varies accordingly, and therefore, the humidity in the pot body cannot be accurately controlled by controlling or adjusting the air volume, air pressure and/or air speed of the hot air heating device by the cooking program. In the cooking system, the humidity sensor is used for dynamically detecting the humidity in the pot body, and the air quantity, the air pressure and/or the air speed of the hot air heating device are controlled or adjusted according to the detection result, so that the humidity in the pot body can be accurately controlled under various conditions, and the cooking quality is improved.

It should be noted that although the cooking system of the present invention is mainly suitable for cooking dishes, especially Chinese dishes, it can be used for cooking various materials requiring heat treatment, such as tea leaves, herbs, melon seeds, peanuts, beans, etc.
