Abstract
The invention discloses a constant-temperature control system used for a drying layer of a grain dryer. The constant-temperature control system comprises an air inlet valve for introducing air, which is arranged on a branch pipeline of a hot air pipeline of the drying layer, a control circuit and a valve motor driven by the control circuit, wherein the control circuit comprises a micro processor as well as a temperature sensor and a drive circuit connected to the micro processor; and the temperature sensor is arranged in a drying room. According to the constant-temperature control system, when the temperature of the drying room exceeds a set drying temperature, the temperature of the drying room can be quickly reduced to a needed temperature, so that the temperature of the drying room is guaranteed to be always kept at a constant temperature in a drying process, and the quality of the grains is guaranteed in the drying process.
Description
Technical field
The present invention relates to foodstuff drying device technical field of temperature control, be specifically related to a kind of thermostatic control system for 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, a kind of device that can quickly reduce hot blast temperature of exploitation is needed badly.
Summary of the invention
The purpose of the present invention is aiming at above-mentioned deficiency, it is provided that a kind of can quickly reduce the thermostatic control system for foodstuff drying device drying layer of hot blast temperature in drying course.
Technical scheme is as follows:
A kind of thermostatic control system for 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.Air inlet valve that described thermostatic control system includes being arranged on lateral, control circuit and the valve driving machine driven by control circuit, wherein control circuit includes microprocessor and the temperature sensor being attached thereto and drive circuit；Described temperature sensor is arranged in hothouse.
Further, it is provided with A/D converter between described temperature sensor and microprocessor.
Further, described temperature sensor has at least one.
Beneficial effects 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, temperature is made to be quickly reduced to temperature required, it is effectively ensured hothouse temperature in drying course, remains at steady temperature, be effectively ensured corn quality in dry run.
Accompanying drawing explanation
Fig. 1 is the structural representation that the embodiment of the present invention is applied to foodstuff drying device drying layer；
Fig. 2 is the module connection figure of the thermostatic control system of the embodiment of the present invention；
Fig. 3 is another example structure schematic diagram that the present invention is applied to foodstuff drying device drying layer.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technical scheme is clearly and completely described.
Embodiment 1
The present embodiment provides a kind of thermostatic control system for foodstuff drying device drying layer.The foodstuff drying device drying layer structure of the present embodiment is as shown in Figure 1.Wherein, drying layer includes air inlet, hothouse and exhaust outlet, and described air inlet is connected with hot air duct, and the other end of hot air duct is connected with hot air generator.Hot air duct is provided with the branch line being connected with air, and the air inlet valve 1 that thermostatic control system described in the present embodiment comprises just is arranged on lateral.
Accompanying drawing 2 is the module connection figure of the thermostatic control system of the present embodiment.By accompanying drawing 2 it can be seen that the control system of the present invention is except being included into air-valve 2, also including by control circuit 2 and the valve driving machine 3 that driven by control circuit 2, wherein control circuit 2 includes microprocessor 21 and the temperature sensor 22 being attached thereto and drive circuit 23；Described temperature sensor is arranged in hothouse (see accompanying drawing 1).A/D converter 24 it is additionally provided with between temperature sensor 22 and microprocessor 21.
In the present embodiment, the operation principle of thermostatic control system is as follows: temperature sensor 22 gathers the temperature of hothouse, the temperature information collected is transferred to microprocessor 21 after being converted to digital quantity by A/D converter 24, and the microprocessor 21 temperature data to collecting and preset temperature range contrast；When hothouse temperature is higher than the preset temperature upper limit, microprocessor 21 controls valve driving machine 3 and drives air inlet valve 1 to open, thus natural wind relatively low for ambient temperature is introduced hothouse, makes hothouse temperature be quickly reduced to temperature required.
The thermostatic control system of the present embodiment can be effectively ensured hothouse temperature and remain at steady temperature in drying course, is effectively ensured corn quality in dry run, it is prevented that corn receives the impact of high temperature and produces quick-fried waist.
Embodiment 2
The control system of the present embodiment is with embodiment 1, but is provided with multiple temperature sensor in hothouse, sees accompanying drawing 3.Multiple temperature sensors the accuracy that can be effectively improved temperature data acquisition is set.
Above example is only the preferred embodiments of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.Simultaneously, the explanation of above example is only intended to help to understand method and the core concept thereof of the present invention, for one of ordinary skill in the art, thought according to the present invention, all will change in specific embodiments and applications, in sum, this specification content should not be construed as limitation of the present invention.
