Abstract
The utility model discloses an experiment-type electric heating circulating system which comprises a heating tank. The heating tank is communicated with an outer hollow chamber of a casing pipe through a pump, and an inner hollow chamber of the casing pipe is communicated with a material tank. According to the experiment-type electric heating circulating system, an indirect circulating electric heating mode is used as a heating mode so that size is small, practicability is strong, and the experiment-type electric heating circulating system can be widely used in experimental research and development in food industry; a piping and instrument diagram (PID) is used to control so that temperature is stable, energy consumption is little, and instant sterilization can be conducted on materials; and heat preserving layers are arranged outside all pipelines and a heating device so as to be favorable for stability of heating of the materials.
Description
Technical field
The utility model relates to a kind of experiment type electric heating circulation system.
Background technology
Present present stage, Electric heating commonly used had direct heating and indirect chuck heating dual mode.Directly Electric heating is directly to be placed on electric heater in the container of filling material, and electric heater is prone to coated by material, and the heat exchange weak effect can not reach the food hygiene requirement, and is overheated in the local generation of electric heater sometimes.It is slow to heat up, and temperature is unstable.The chuck mode of heating is to come the material heating at jacket canister internal layer placement electric heater and conduction oil indirectly, and its each material treating capacity is also very big, but its volume is too big, is not suitable for testing usefulness, the heat exchange weak effect, and it is slow to heat up, and temperature is unstable.
The utility model content
In order to solve the problem that above-mentioned prior art exists, the purpose of the utility model is to propose a kind of experiment type electric heating circulation system, and it can effectively solve the problems referred to above that prior art exists.
For realizing above-mentioned purpose, the utility model can solve through following technical scheme:
A kind of experiment type electric heating circulation system, it comprises a heating tank, this heating tank is communicated with the external cavity of a sleeve pipe through a pump, and the internal cavities of this sleeve pipe is communicated with material pot.
As the further technical characterictic of the utility model, said jacket exterior is provided with a heat-insulation layer.
As the further technical characterictic of the utility model, be provided with a heater in the said heating tank, this heater is connected with a control system.
As the further technical characterictic of the utility model, said control system is a PID control system.
Owing to adopt above technical scheme, it is the indirect cyclic process Electric heating that a kind of experiment type electric heating circulation system of the utility model adopts mode of heating, and volume is little, and is practical, can be widely used in the experiment research and development of food service industry; Adopt PID control, temperature stabilization, energy consumption is little, but to the material instantaneous sterilization; All pipelines and heater outside are designed with heat-insulation layer, are beneficial to the stable of material heating.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is direct-fired structural representation.
Fig. 3 is the structural representation of indirect chuck heating.
Among the figure: 1, heater; 2, heating tank; 3, pump; 4, heat-insulation layer; 5, external cavity; 6, internal cavities; 7, material pot; 8, conduction oil.
The specific embodiment
Below in conjunction with the specific embodiment, further set forth the utility model:
As shown in Figure 1, a kind of experiment type electric heating circulation system, it comprises a heating tank 2; Be provided with a heater 1 in the heating tank 2, in the present embodiment, this heater 1 is the heater 1 of PID type control system; Owing to adopted PID control system; Temperature is comparatively stable, and the accuracy of its temperature can reach ± 0.3 degree, good effect of heat exchange.Heat-conducting liquid through heater 1 heating in the heating tank 2 has imported in the outer cavity 5 of a sleeve pipe through a pump 3; And form a loop, the material of required heating is conducting in the internal cavities 6 of sleeve pipe, and the flow direction of the heat-conducting liquid in its flow direction and the jacket exterior cavity 5 is opposite; Can be heated to needed temperature in the process that material flows in sleeve pipe; Heat-conducting liquid can be cooled and flow back into simultaneously in the heating tank 2, by heater 1 heating, so is concatenated to form circulation once more.And have jacket exterior to be provided with a heat-insulation layer 4, and place the thermal loss of the heat-conducting liquid in the external cavity 5, be beneficial to the stable of material heating.
Traditional mode of heating has two kinds, and a kind of is direct Electric heating, is directly to be placed on heater 1 in the material pot 7 of filling material; A kind of is indirect chuck mode of heating, be to place heater 1 in the internal layer in material pot 7 to come the material heating with conduction oil 4, and material pot 7 outsides is provided with a heat-insulation layer 8; Compare with traditional mode of heating, the temperature stabilization of the experiment type electric heating circulation system of the utility model, energy consumption is little, but to the material instantaneous sterilization.
But the above-mentioned specific embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
