Description
Technical field
The present invention relates to food processing field, food drying device is specifically referred to.
Background technology
At present in all kinds of boiler uses, boiler utilization rate is improved in order to reach, reduce the purpose of boiler energy consumption, recycling to after-heat contained by boiler exhaust gas, conventional method is to install heat exchanger additional at boiler exhaust gas flue, the pre-heat treatment is carried out to air or water needed for boiler etc. using tail gas institute's heat content, to reduce boiler energy consumption, but find in actual use, even if after being carried out by heat exchanger, heat in boiler exhaust gas has greatly reduced, but still contain heat higher, still can be used as the thermal source for needing slow heating or drying purposes, and be typically all at present that directly these after-heats are directly discharged with boiler exhaust gas, cause the wasting of resources.
The content of the invention
It is an object of the invention to provide food drying device, to overcome above mentioned problem.
The purpose of the present invention is achieved through the following technical solutions：
Food drying device, including casing, heat conduction frame is installed in the casing, the through hole picked and placeed for food is provided with the upper portion side wall of casing, the steam vent connected with box house is provided with casing top, magnetic valve is installed in steam vent, heat exchanging chamber is offered in the heat conduction frame, heat exchanger tube is placed in the heat exchanging chamber through the cabinet exterior, it is conformed with heat conduction top of the trellis, heated sheet is placed on the projection upper end, and sliding groove is offered in projection, heated sheet bottom is provided with multiple rollers, and the roller-coaster is arranged in sliding groove；Also include pressure sensor, the pressure sensor is arranged in steam vent and is connected with the magnetic valve；Spring is separately installed with the two ends of the heated sheet, and the two ends of the heated sheet are connected by spring with the inwall of the casing respectively.
During present invention work, directly the secondary boiler exhaust gas for using are injected into heat exchanger tube, the air that the temperature of heat exchanger tube starts in heat exchanging chamber after drastically raising is heated, the heat of outer row is passed up on heated sheet by heat conduction frame on heat exchanger tube simultaneously, and the food for being placed on heated sheet in advance then starts to be heated by the heat transfer of heated sheet, heat during first use is less than due to the secondary boiler exhaust gas heat for using, therefore the food for needing such as to dry, bakee operation is suitably placed on heated sheet.And, through hole, steam vent are had in the upper portion side wall of casing and its top, the food that through hole is used in process is picked and placeed, and steam vent is used to be discharged when the air pressure heat of box house is drastically raised the gas or heat of a part, it is too high and cause security incident to be prevented effectively from cabinet wall air pressure, or prevent food baking from excessively scrapping.The present invention in use, i.e., the operation such as can be dried, bakee to food, at the same the tail gas of boiler is carried out it is secondary use, the use cost of food processing is greatly reduced, while realizing the Multi-class propagation of the energy.
Wherein, the pressure sensor of installation can real-time detection box house temperature conditions, when the air expansion of box house causes internal pressure drastically to raise, pressure sensor transmits control command in the magnetic valve to steam vent, the opening valve of low-angle is carried out to regulate and control magnetic valve, by discharging the heat and air of a part, to maintain the normal pressure of box house, on the premise of ensureing that food is baked completion, it is to avoid the generation of security incident.When food is picked and placeed, heated sheet does horizontal rectilinear motion by roller on heat conduction frame, when heated sheet is moved to the extreme position of sliding groove, the end of heated sheet can collide with cabinet wall, and or the roller of heated sheet bottom can collide with sliding groove, so that heated sheet, sliding groove or cabinet wall are subject to different degrees of damage, and the spring installed in the present invention, may be such that heated sheet and cabinet wall, the applied stress that collision between roller and sliding groove is produced directly fall by buffering, and then reduce the extent of damage of each part collision, to extend service life of the invention.
Also include heat-insulation layer, the heat-insulation layer is wrapped on the outer wall of the casing.When the operation such as food drying or baking is carried out, the drying such as such as kernel makes, need processing duration more long, therefore it is higher to the sustainable requests of thermal source, heat-insulation layer is installed on the outer wall of casing in the present invention, food that can be in guard box body can be carried out in processing with a relatively stable constant temperature, improve the processing efficiency of food.
The heat exchanger tube is at least 2, and serpentine-like is distributed in heat exchanging chamber.Heat exchanger tube is set to more than 2 so that distribution of the heat exchanger tube in heat exchanging chamber is more uniform, more stablize effective heat to facilitate heat conduction frame to be provided as heated sheet.
The roller is steel ball roller.Preferably, the steel ball roller selected can carry out stable operation under the condition of work higher than normal temperature, that is, ensure that picking and placeing for food is more convenient.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention in use, i.e., the operation such as can be dried, bakee to food, at the same the tail gas of boiler is carried out it is secondary use, the use cost of food processing is greatly reduced, while realizing the Multi-class propagation of the energy；
2nd, the present invention is provided with heat-insulation layer on the outer wall of casing, it is ensured that the food in casing can be carried out in processing with a relatively stable constant temperature, improve the processing efficiency of food；
3rd, the steel ball roller that the present invention is selected can carry out stable operation under the condition of work higher than normal temperature, that is, ensure that picking and placeing for food is more convenient.
