Abstract
The invention provides a constant-temperature control method of a drying layer of a grain drying machine. According to the constant-temperature control method provided by the invention, a hot air pipeline of a drying chamber is additionally provided with an air inlet valve capable of introducing natural air, and the air inlet valve can be automatically opened and closed according to the temperatures so as to keep a constant temperature of the drying chamber; and when the temperature of the drying chamber exceeds a pre-set temperature upper limit, the air inlet valve is automatically opened and the natural air with the relatively low temperature on the outer side is introduced, so that the temperature of the drying chamber is reduced. With the adoption of the method provided by the invention, when the temperature of the drying chamber exceeds a pre-set drying temperature, the temperature of the drying chamber is rapidly reduced to a needed temperature, so that a condition that the temperature of the drying chamber keeps the constant temperature in a drying process all the time is effectively guaranteed, and the quality of grains in the drying process is ensured.
Description
Technical field
The present invention relates to foodstuff drying device technical field of temperature control, be specifically related to the constant-temperature control method of a kind of foodstuff drying device drying layer.
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.
Existing foodstuff drying device controls often to gather drying chamber Temperature Feedback for the temperature in drying course and controls the flow process of the hot blast temperature that hot air generator produces to control module control module, this feedback mechanism is relatively slow, too high longer to reducing hot blast temperature flow process from collecting drying temperature.Therefore, need exploitation badly and a kind of can quickly reduce hothouse temperature thus ensureing the control method of hothouse constant temperature.
Summary of the invention
The purpose of the present invention is aiming at above-mentioned deficiency, it is provided that a kind of quickly can reduce temperature when hothouse temperature is too high thus keeping the constant-temperature control method of the foodstuff drying device drying layer of hothouse constant temperature.
Technical scheme is as follows:
A kind of constant-temperature control method of foodstuff drying device drying layer, described drying layer includes air inlet, hothouse and exhaust outlet, described hothouse is connected with the shunting layer of foodstuff drying device, described air inlet is connected with hot air duct, the other end of hot air duct is connected with hot air generator, and hot air duct is provided with the branch line being connected with air.Described constant-temperature control method can according to the air inlet valve of temperature height automatically open and close to keep the constant temperature of hothouse by arranging on branch line；When hothouse temperature exceedes the design temperature upper limit, air inlet valve automatically opens up, and introduces the natural wind that ambient temperature is relatively low, and then reduces hothouse temperature.
Further, described air inlet valve accepts the control of valve driving machine, and described valve driving machine is driven by control circuit.
Further, described control circuit includes microprocessor and the temperature sensor being attached thereto and drive circuit.
Yet further, it is provided with A/D converter between described temperature sensor and microprocessor.
Yet further, described temperature sensor is located in hothouse.
The constant-temperature control method flow process of the present invention is as follows: temperature sensor gathers the temperature of hothouse, and the microprocessor temperature data to collecting and preset temperature range contrast；When hothouse temperature is higher than the preset temperature upper limit, microprocessor controls valve driving machine and drives air inlet valve to open, thus natural wind relatively low for ambient temperature is introduced hothouse, makes temperature be quickly reduced to temperature required；Once hothouse temperature is reduced to preset range, microprocessor controls valve driving machine and drives air inlet valve to cut out, and maintains the steady temperature of hothouse.
The present invention has the following technical effect that the switch by air inlet valve is effectively ensured hothouse temperature and maintains steady temperature in drying course all the time, it is ensured that corn quality in dry run, reduces owing to drying the too high quick-fried waist caused of temperature.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technical scheme is clearly and completely described.
The present invention provides the constant-temperature control method of a kind of foodstuff drying device drying layer, and described constant-temperature control method can according to temperature height automatically open and close to keep the constant temperature of hothouse by setting up the air inlet valve that can introduce natural wind and this air inlet valve on the hot air duct of hothouse；When hothouse temperature exceedes the design temperature upper limit, air inlet valve automatically opens up, and introduces the natural wind that ambient temperature is relatively low, and then reduces hothouse temperature.
The following is specific embodiments of the invention.
As shown in Figure 1, the constant-temperature control method flow process of the present embodiment is as follows: temperature sensor gathers the temperature of hothouse, the temperature information collected is transferred to microprocessor after being converted to digital quantity by A/D converter, the microprocessor temperature data to collecting and preset temperature range contrast；When hothouse temperature is higher than the preset temperature upper limit, microprocessor controls valve driving machine and drives air inlet valve to open, thus natural wind relatively low for ambient temperature is introduced hothouse, makes hothouse temperature 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 to cut out.
Accompanying drawing 2 is the system module schematic diagram that the constant-temperature control method of the embodiment of the present invention relates to.This control system is included into air-valve 1, also includes by control circuit 2 and the valve driving machine 3 that driven by control circuit 2, and wherein control circuit 2 includes microprocessor 21 and the temperature sensor 22 being attached thereto and drive circuit 23.A/D converter 24 it is additionally provided with between temperature sensor 22 and microprocessor 21.
Accompanying drawing 3 is the structural representation of the foodstuff drying device drying layer of application embodiment of the present invention constant-temperature control method.Described drying layer includes air inlet, hothouse and exhaust outlet, described hothouse is connected with the shunting layer of foodstuff drying device, described air inlet is connected with hot air duct, and the other end of hot air duct is connected with hot air generator, and hot air duct is provided with the branch line being connected with air；Branch line is provided with can according to the air inlet valve 1 of temperature height automatically open and close to keep the constant temperature of hothouse；Temperature sensor 22 it is provided with in hothouse.
The constant-temperature control method of the present embodiment can be effectively ensured hothouse temperature and remain at steady temperature in drying course, it is ensured that corn quality in dry run, it is prevented that corn receives the impact of high temperature and produces quick-fried waist.
