Detailed Description

The above and further features and advantages of the present invention will be apparent from the following, complete description of the invention, taken in conjunction with the accompanying drawings, wherein the described embodiments are merely some, but not all embodiments of the invention.

In one embodiment, as shown in fig. 1 and 2. The present embodiment provides a food fryer including a food feeding device 1, a food frying device 2 located at a subsequent stage of the food feeding device 1, and a controller 3 connecting the food feeding device 1 and the food frying device 2. The food feeding device 1 comprises a conveying unit 101 and a first weighing unit 102; the conveying unit 101 is used for conveying the food to a later stage; the first weighing unit 102 is used for acquiring a first weight value of the food conveyed to the rear stage; in a preferred embodiment, a weighing conveyer belt may be used instead of the conveying unit 101 and the first weighing unit 102, and the food items may be both conveyed to a later stage and weighed. The food frying device 2 comprises an oil tank 201, a heating pipe 202 positioned in the oil tank 201, a supply pipe 203 connected with the bottom of the oil tank 201, an edible oil storage tank 204 positioned below the oil tank 201, a one-way supply structure 205 and a lifting pump 206 connected between the supply pipe 203 and the edible oil storage tank 204, and a second weighing unit 207 arranged at the bottom of the oil tank 201; the second weighing unit 207 is used for acquiring a second weight value of the oil tank 201; in the present embodiment, the oil tank 201 and the heat generating pipe 202 may adopt a conventional structure. The food frying apparatus 2 according to the present embodiment is improved in that a supply pipe 203, an edible oil storage tank 204, a one-way supply structure 205, a lift pump 206, and a second weighing unit 207 are added, so that the food frying apparatus 2 can add oil into the oil tank 201 according to the actual oil amount of the oil tank 201. In the present embodiment, the actual amount of fuel in the fuel tank 201 is based on the weight difference generated by the first weight value and the second weight value. During frying, the food tends to suck up the oil in the oil tank 201, and therefore the amount of oil not actually contained in the oil tank 201 is obtained only by the second weighing unit 207. Accordingly, in this embodiment, the controller 3 is connected to the first weighing unit 102, the second weighing unit 207, and the lift pump 206; the controller 3 is used for receiving the first weight value and the second weight value and generating a weight difference value according to a difference function formula; when the weight difference is greater than the preset value, the controller 3 controls the lift pump 206 to add a preset amount of oil into the oil tank 201. Therefore, in the present embodiment, a preset amount of oil can be added to the oil tank 201 from bottom to top in a unidirectional manner, and since the oil is added from the bottom of the oil tank 201 through the supply pipe 203, the operator can be prevented from being splashed with the hot oil.

In one embodiment, as shown in FIG. 3. The food frying apparatus 2 provided in this embodiment further includes a dredging pressing plate 208 disposed in the oil tank 201; the dredging press plate 208 covers the upper part of the supply pipe 203; the channeling press plate 208 includes a plate body 208a, a pipe groove 208b opened on the plate body 208a and providing an insertion of the upper end portion of the supply pipe 203, and a plurality of channeling manifolds 208c opened on the plate body 208a and connected around the pipe groove 208 b; the plate body 208a is pressed in the oil tank 201, so that the plurality of dredging manifolds 208c only form ports at the end parts of the dredging paths; wherein the plurality of canalizing manifolds 208c are diffused along the circumference of the tube groove 208b in all directions. In this embodiment, the oil pumped up from the edible oil storage tank 204 by the lift pump 206 passes through the dredging pressure plate 208 and then spreads around at the bottom of the oil tank 201. Therefore, the temperature unevenness of the oil in the oil tank 201 caused by the fact that the oil temperature is too low can be avoided. Since the deflector plates 208 in this embodiment inhibit the oil just drawn up from spreading upward and spreading only at the bottom of the oil tank 201, the influence on the fried food can be reduced. In the present embodiment, the oil just drawn up is blocked by the plate body 208a and spreads in all directions around along the plurality of dredging manifolds 208 c. The diffusion path in each of the canalizing manifolds 208c canalize the canalizing path of the manifold 208c itself. In this embodiment, the supply pipe 203 and the dredging platen 208 may be used to preheat the oil just drawn up.

In one embodiment, as shown in FIG. 4. The present embodiment provides a unidirectional supply structure 205 for unidirectionally adding oil into the oil tank 201 from bottom to top. It comprises an inner core piece 205a, an outer sleeve piece 205b, an upper fixed end sleeve 205c, and a lower fixed end sleeve 205 d; the outer external sleeve 205b is fixed to the inner core piece 205a by means of an upper fixed end sleeve 205c and a lower fixed end sleeve 205d, and an intermediate channel 205e is formed between the outer external sleeve 205b and the inner core piece 205 a; an upper end portion of the inner core piece 205a is provided with an upper channel 205f and an upper connection port 205g connecting the upper channel 205f and the intermediate channel 205e, and a lower end portion of the inner core piece 205a is provided with a lower channel 205h and a lower connection port 205i connecting the lower channel 205h and the intermediate channel 205 e; the upper channel 205f, the middle channel 205e, and the lower channel 205h are connected in sequence; the one-way feed structure 205 further includes a spring 205j that fits over the inner shaft core piece 205a and within the intermediate channel 205e and a piston seal 205k provided at the end of the spring 205 j; when the spring 205j is in a natural state, the piston seal 205k is positioned below the upper connection port 205g, and when the spring 205j is in a compressed state, the piston seal 205k is positioned above the upper connection port 205 g. In this embodiment, there is no communication between the upper channel 205f and the lower channel 205h, blocked by the piston seal 205 k. But after the piston seal 205k receives the upward pressure from below, it can move upward until it is higher than the upper connection port 205g, and the upper passage 205f and the lower passage 205h communicate with each other. Thereby drawing oil from the lower gallery 205h to the intermediate gallery 205e, and from the intermediate gallery 205e to the upper gallery 205 f. The above process requires the lift pump 206 to provide sufficient pressure. In the present embodiment, the stiffness coefficient of the spring 205j may be relied on to prevent the oil in the oil tank 201 from flowing backward. In another embodiment, the oil in the oil tank 201 may be prevented from flowing backward by means of a stopper structure (not shown) disposed in the middle channel 205e and below the upper connection port 205 g.

In this embodiment, the handle 204d and the box wheel 204c are provided to facilitate the movement of the edible oil storage box 204.

In one embodiment, as shown in FIG. 6. The heat generating tube 202 provided in the present embodiment includes a fixing member 202a, a first tube group 202b, a second tube group 202c, and a third tube group 202 d; the fixing member 202a is provided on a side wall of the oil tank 201; the first tube group 202b, the second tube group 202c and the third tube group 202d are respectively connected to the fixing member 202a and extend downward to be close to the bottom in the oil tank 201; the first tube bank 202b, the second tube bank 202c, and the third tube bank 202d form respective heating zones. In this embodiment, the heating tube 202 is divided into the first tube group 202b, the second tube group 202c and the third tube group 202d which can operate in three heating zones, so as to ensure uniform heating in the oil tank 201 and improve the frying effect of the food.
