Description

Technical Field

[0001] The present invention relates to the technical field of drying equipment, and more specifically, to a corn seed dehydration device. Background Art

[0002] In the prior art, corn is divided into common corn and fresh corn, and fresh corn is further divided into sweet corn, waxy corn, and sweet plus waxy corn. A reasonable drying process can reduce seed fission and improve the germination rate and vitality of seeds. After the corn seeds mature, they need to be dehydrated to about 13% moisture for storage. Common corn seeds often contain a relatively high moisture content (25%-45%) when harvested, and the moisture content of fresh corn seeds can reach 60-70% when harvested. Through drying, the safe moisture content can be quickly reached, which is convenient for long-term storage. Corn seed dehydration is a key process in corn seed production.

[0003] Currently, the main dehydration methods for corn seeds are natural sun drying and heating drying. Although natural sun drying saves energy, it sometimes rains, especially in the south where the weather is changeable, and sun drying of seeds is often not guaranteed. Moreover, it takes a large amount of labor to collect and dry seeds every day, and the vitality and germination rate of the seeds cannot be guaranteed. Although the germination rate and seed vitality can be guaranteed by using a dryer for heating drying, it consumes a large amount of energy and the equipment is relatively expensive.

[0004] Therefore, how to provide a new corn seed dehydration device that can dry quickly at high temperature and continuously at low temperature while having the characteristics of low energy consumption is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a corn seed dehydration device, aiming to solve the technical problems of high energy consumption and high cost of traditional dryers.

[0006] A corn seed dehydration device includes:

[0007] A drying room, with an air inlet and an air outlet opened on both sides of the drying room;

[0008] A heating chamber, the outlet of the heating chamber is connected to the air inlet through pipeline one;

[0009] A drying chamber, the outlet of the drying chamber is connected to the inlet of the heating chamber through pipeline two;

[0010] A first fan, the suction port of the first fan is connected to the air outlet through pipeline three, and the blowing port of the first fan is connected to the inlet of the drying chamber through pipeline four;

[0011] A drying and cooling system, which includes a condensation part, a compressor, a heat dissipation part and an expansion valve connected in series by copper pipes and in a closed-loop connection. A refrigerant medium flows in the copper pipes. The heat dissipation part is installed in the heating chamber and the refrigerant medium inside it is at high temperature and high pressure. The condensation part is installed in the drying chamber and the refrigerant medium inside it is at low temperature and low pressure. The compressor compresses the refrigerant medium at low temperature and low pressure in the condensation part into a refrigerant medium at high temperature and high pressure and discharges it into the heat dissipation part. The expansion valve is used to convert the refrigerant medium at high temperature and high pressure in the heat dissipation part into a refrigerant medium at low temperature and low pressure in the condensation part.

[0012] Through the above technical solution, the present invention connects the drying room, the first fan, the drying chamber and the heating chamber in sequence through pipelines. The air in the drying room is extracted by the first fan and then processed through the drying chamber and the heating chamber in sequence and then discharged back into the drying room. The air in the drying room is circulated and dried and heated to dehydrate the corn seeds in the drying room. During this air circulation process, in the drying step, the moisture in the air will condense on the surface of the low-temperature condensation part. In the heating step, the heat emitted by the high-temperature and high-pressure refrigerant medium itself after the low-temperature and low-pressure refrigerant medium is compressed by the compressor is used to heat the dried air. The heat generated after the compression of the refrigerant medium is fully utilized, energy waste is avoided, power consumption is reduced, and at the same time, the dehydration effect of the corn seeds is improved.

[0013] Preferably, it further includes a first valve, and the first valve is installed on pipeline one.

[0014] Preferably, it further includes a second valve. The outlet of the drying chamber is communicated with the air inlet through pipeline five, and the second valve is installed on pipeline five.

[0015] Preferably, it further includes a shelf. The shelf is placed in the drying room, and the corn seeds to be dried are placed on the shelf.

[0016] Preferably, the air inlet is located at the bottom position of the wall of the drying room, and the air outlet is located at the top position of the wall of the drying room to form an air circulation path from low to high in the drying room.

[0017] Preferably, a condensate outflow pipe is arranged at the bottom end of the drying chamber.

[0018] Preferably, the condensation part has two groups of condensation fins.

[0019] Preferably, the heat dissipation part has two groups of heat dissipation fins.

[0020] Preferably, the drying room is a closed and heat-insulated room with a volume of 60 - 90 cubic meters.

[0021] Preferably, the number of shelves is multiple and they are evenly distributed in the drying room.

[0022] As can be seen from the above technical solutions, compared with the prior art, the present invention discloses a corn seed dehydration device, which has the following beneficial effects: through the mutual cooperation of components such as a drying room, a heating chamber, a drying chamber, a fan, and a drying and cooling system, a closed-loop air circulation system is formed. Utilizing the compression and expansion characteristics of the refrigerant medium, energy is efficiently utilized, enabling both high-temperature rapid drying and low-temperature continuous drying. It solves the problems of high energy consumption and high equipment cost in the existing corn seed dehydration devices, effectively reducing energy consumption, improving the drying effect, reducing seed fission, and increasing the germination rate and vitality of the seeds.
