The invention discloses a grain dryer with an automatic drying-layer constant-temperature control device. The grain dryer comprises a base, and a bottom layer, a drying layer, a flow distribution layer and a storage layer are sequentially arranged on the base from bottom to top. The drying layer is provided with a blast inlet which is connected with a hot blast pipeline, the other end of the hot blast pipeline is connected with a hot blast stove, and the hot blast pipeline is further connected with an air pipeline. The air pipeline is provided with an air inlet valve which is controlled by a valve motor driven by a control circuit, and the air inlet valve can be automatically opened or closed according to the temperature of the drying layer. According to the grain dryer, through the automatic drying-layer constant-temperature control device, outside natural air which is low in temperature can be introduced into the hot blast pipeline when the temperature of the drying layer is too high and then can be further introduced into the drying layer, so that the temperature of the drying layer is quickly reduced; the effect that the temperature of the drying layer is kept constant all the time in the drying process is effectively guaranteed, and the quality of grains in the drying process is guaranteed.
Description
Technical field
The present invention relates to foodstuff drying device technical field, be specifically related to a kind of foodstuff drying device with drying layer automatic thermostatic controller.
Background technology
Grain crack rate is the important indicator of evaluation Oryza glutinosa technological quality. The Oryza glutinosa that percent cracked rice is high, particularly crackle many and deep time, add and be easily broken off man-hour, unsuitable machining high-precision rice, otherwise can make to crack rice increases, reduction rice milling yield, is uneconomic.
The factor producing quick-fried waist is a lot, drought, disease, white harvest excessively, machinery strike, hard hit, and Paddy With High Moisture Content Stored is subject to sharply dry and cooling sharply, or make moist moisture absorption time internal the expansion with surface shrinkage of the grain of rice uneven etc. all can make Cracked Rice. Wherein, in drying course, temperature is too high is one of common cause of causing percent cracked rice high. Therefore, a kind of foodstuff drying device with drying layer automatic thermostatic controller of exploitation is needed badly.
Summary of the invention

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technical scheme is clearly and completely described.
The following is specific embodiments of the invention.
As shown in figure 1 and 2, a kind of foodstuff drying device with drying layer automatic thermostatic controller, described foodstuff drying device includes base 1; Base is disposed with bottom 2, drying layer 3, shunting layer 4 and storage from down to up and stays layer 5, base 1 is also associated with lower screw feeder 8 and elevator 6; Side, elevator bottom is provided with feed hopper 61, and the top of elevator 6 is connected with upper screw feeder 9, and upper screw feeder 9 stays layer 5 to connect with storage; Drying layer 4 connects with dialling grain valve 7, dials grain valve 7 and connects with lower screw feeder 8, and lower screw feeder 8 connects with feed hopper 6a. Being provided with air inlet 3a on drying layer 3, air inlet 3a is connected with hot air duct 10, and the other end of hot air duct 10 connects air stove 11. The key component of the automatic thermostatic controller of the present invention is the air pipe line 12 being connected with hot air duct 10; Air pipe line 12 is provided with air inlet valve 12a, and this air inlet valve 12a, by the control of the valve driving machine driven by control circuit, can be automatically opened or closed according to drying layer 3 temperature height.
Control circuit in the present embodiment includes for processor and the temperature sensor being attached thereto and drive circuit, as shown in Figure 3; Wherein, temperature sensor is arranged on (accompanying drawing 1 is shown) near air inlet 3a. During work, temperature sensor gathers hot blast temperature, and it is transmitted to microprocessor, microprocessor contrast collecting temperature and preset temperature: if collecting temperature exceedes the preset temperature upper limit, microprocessor controls valve driving machine and drives air inlet valve 12a to open, thus natural wind relatively low for ambient temperature is introduced hothouse, hothouse temperature is made to be quickly reduced in preset temperature range; Temperature information is then through being gathered and be transferred to microprocessor by temperature sensor, and microprocessor controls valve driving machine and drives air inlet valve 12a to cut out.
In air pipe line 12, the rear end of air inlet valve 12a is additionally provided with air filter 12b, air filter 12b can be any one in dividing plate high efficiency particulate air filter, non-inductive windings high efficiency particulate air filter, the convolution filter of V-type.Air filter can filter the dust in the air entering hot air duct and solid impurity, keeps hot blast clean, it is to avoid grain to be dried in hothouse is polluted.
In sum, the natural wind that ambient temperature reduces can be introduced hot air duct when hothouse temperature is too high by the automatic thermostatic controller of the present embodiment, and then introducing hothouse, thus quickly reducing hothouse temperature, it is effectively ensured hothouse temperature in drying course, remains at steady temperature, it is ensured that corn quality in dry run.
