Description
Technical field
The utility model relates to initiatively baking and food drying technical field of processing equipment, particularly belongs to a kind of and utilizes solar energy and realize the food baking system and device of control automatically.
Background technology
The technology that dehydrates in the food processing and our life, produce closely bound uply, especially at production fields such as agricultural, chemical industry, food processings, its application is very general.Old-fashioned drying equipment mostly is based upon on the basis of highly energy-consumings such as fuel oil, fire coal, electrical heating, is unfavorable for the resources effective utilization, and has defectives such as environmental pollution, drying efficiency be low.On the other hand, along with being rooted in the hearts of the people of ideologys such as low-carbon energy-saving, environmental protection, sustainable development, solar energy just progressively is subjected to people's common attention and approval as a kind of energy of clean environment firendly.
Summary of the invention
The purpose of this utility model is to provide a kind of novel solar energy foodstuff dryer, with the purpose that reaches safety and environmental protection, efficient energy-saving, increases economic efficiency.
Solar energy foodstuff dryer provided by the utility model, comprise heating plant, drying unit and control appliance, it is characterized in that, described heating plant is made up of solar thermal collector, electric heater, blower fan and gas-liquid heat exchanger, solar thermal collector is connected with incubator, gas-liquid heat exchanger by the forward pipeline, the forward pipeline is provided with circulating pump, and blower fan is positioned at gas-liquid heat exchanger one side, and the shutter of blower fan communicates with the circulation thermal insulation wind pipe; Drying unit is baking room, is provided with radiator and air exhauster in it, and radiator is series in the above-mentioned forward pipeline; Described control appliance, control centre is CPU, its input connects the input unit of power module, temperature sensor, humidity sensor and setup parameter, and output connects circulating pump motor drive circuit, blower motor drive circuit, electric heater drive circuit and magnetic valve.
Solar energy foodstuff dryer provided by the utility model, when work, solar thermal collector is radiator and gas-liquid heat exchanger supplied heat source by the forward pipeline with water, the heating of heat conduction wet goods liquid medium then; Under the effect of blower fan, enter baking room via the gas-liquid heat exchanger heated hot air heated, gas part in the baking room enters gas-liquid heat exchanger again by the circulation thermal insulation wind pipe and heats, and another part contains the more air of moisture and is discharged to outside the baking room by air exhauster.
In addition, the temperature sensor in the baking room and humidity sensor detect temperature value and the humidity value in the baking room in real time, and when temperature value was lower than setting value, CPU control strengthened each valve opening, and improved the rotating speed of blower motor and circulating pump motor; When the rotating speed of valve opening, blower motor and circulating pump motor reaches maximum, but opening electric heater when not reaching the temperature value that sets yet in the baking room; When temperature value surpassed setting value, electric heater was closed in CPU control, reduces the aperture of each valve, reduces the rotating speed of blower motor and circulating pump motor.
The drying of general agricultural byproducts and food requires temperature levels lower, greatly between 40-70 degree centigrade, this just in time adapts with the temperature in solar energy heating field, the utility model can be saved conventional energy resource in a large number, remarkable in economical benefits has the good effect of efficient energy-saving, stable performance, cleanliness without any pollution.
Description of drawings
The accompanying drawing device discloses specific embodiment of the utility model, wherein,
Fig. 1, the utility model overall structure schematic diagram;
Fig. 2, the utility model control system logic diagram;
Fig. 3, the utility model CPU FB(flow block).
The specific embodiment
As shown in Figure 1, solar energy foodstuff dryer provided by the utility model, comprise heating plant, drying unit and control appliance 20, described heating plant is made up of solar thermal collector 1, electric heater 18, blower fan 6 and gas-liquid heat exchanger 7, the forward pipeline 16 of solar thermal collector is connected with incubator 3, gas-liquid heat exchanger, which is provided with circulating pump 5, blower fan is positioned at gas-liquid heat exchanger one side, and the shutter 9 of blower fan communicates with circulation thermal insulation wind pipe 8; Solar thermal collector will be supplied to radiator in gas-liquid heat exchanger 7 and the baking room by the forward pipeline after the flow media heating, and afterwards, the flow media that the temperature that flows out in the baking room is lower still flows back in the solar thermal collector by back pipeline 17; In addition, can be its additional medium source by replenishing case 4 also.
In the present embodiment, described flow media is preferably water, has good fluidity, low, the few accumulation of cost, free of contamination characteristics.Certainly, can be conduction oil also, have same characteristic and effect.Be example with water below, be described further.
The reserve tank 2 in addition that is connected with incubator, its oral siphon is provided with magnetic valve 14, the size that CPU regulates hot-water supply by the control magnetic valve.
Described electric heater as the auxiliary equipment of heat supply, when only depending on solar thermal collector to satisfy, provides hot water by electric heater for equipment.
Described drying unit is baking room 10, has door 15, and its madial wall is provided with radiator 19 and air exhauster 11, and baking room top one side opening is connected with circulation thermal insulation wind pipe 8, and temperature sensor 12 and humidity sensor 13 are installed in the baking room; Enter under the effect of blower fan via the hot-air after the gas-liquid heat exchanger heating and to be used for dry products in the baking room, a cooled gas part enters gas-liquid heat exchanger again by the circulation thermal insulation wind pipe and heats under the effect of blower fan, another part contains the more air of moisture and then is discharged to outside the baking room by air exhauster 11.
