Description

Technical Field

[0001] The utility model belongs to the technical field of drying devices, in particular to a far-infrared crop drying machine. Background Art

[0002] In the agricultural field, especially for crops with high water content such as rice, pepper, and Chinese medicinal materials, drying after harvesting or picking is a crucial step. If these crops are not dried in time, the excessive moisture content will easily lead to mold, which will seriously affect their quality and storage period. Therefore, efficient and uniform drying methods are essential to ensure the quality of crops and long-term storage.

[0003] At present, most of the crop dryers widely used in the market adopt the traditional air heating method. These dryers usually blow hot air directly upward from the bottom of the drying drum, trying to dry the crops through the convection of hot air. However, this method has many shortcomings: first, due to the rising characteristics of hot air, the crops at the bottom of the drying drum are often heated first, while the crops at the top may not be dried evenly due to insufficient heating; second, this heating method usually has a slow heating speed, low thermal efficiency, and requires a lot of energy and time; finally, in order to ensure that the crops are dried evenly, it is usually necessary to manually turn the crops many times, which increases the complexity and cost of the operation.

[0004] Therefore, there is an urgent need for a far-infrared crop dryer that can improve crop drying effect and reduce energy consumption and labor costs. Utility Model Content

[0034] See attached Figure 1 To Attachment Figure 5 , the figure shows a specific embodiment of a far-infrared crop drying machine provided by the utility model.

[0035] See attached Figure 2 and attached Figure 3 , far infrared crop drying machine includes:

[0036] The chassis 1 has an air inlet 110 on the side thereof and a drying port 120 on the top thereof;

[0037] An evaporator 2 and a condenser 3 are installed in the chassis 1, and the evaporator 2 and the condenser 3 are close to the air inlet 110;

[0038] A motor 4 installed in the chassis 1, the motor 4 is used to draw air from the air inlet 110 and pass through the evaporator 2 and the condenser 3 to generate heat energy;

[0039] A graphene far-infrared heating plate 5 is disposed on the motor 4, and the graphene far-infrared heating plate 5 is close to the drying port 120, and is used to radiate heat energy to the drying port 120;

[0040] A drying drum 6 is mounted on the housing 1 and covers a drying port 120 for placing crops to be dried.

[0041] See attached Figure 2 and attached Figure 3 In the above embodiment, a compressor 7 is further provided in the chassis 1. The compressor 7 is used to absorb low-temperature and low-pressure refrigerant gas from the evaporator 2 and compress it into high-temperature and high-pressure gas. In the above embodiment, a fan 410 is also provided on the motor 4. In the embodiment, the compressor 7 absorbs low-temperature and low-pressure refrigerant gas from the evaporator 2, and compresses the refrigerant into high-temperature and high-pressure gas by doing work. The high-temperature and high-pressure gas enters the condenser 3 and exchanges heat with the air through the action of the fan 410. It is condensed into high-pressure and low-temperature liquid in the condenser 3 and releases a large amount of heat. The air absorbs the released heat and the temperature continues to rise. After throttling and reducing the pressure, the high-pressure and low-temperature liquid absorbs heat from the surrounding air through the action of the fan 410 in the evaporator 2, thereby volatilizing into low-pressure gas, which is then sucked into the compressor 7 for compression. After repeated cycles, the air temperature is increased. See the attached figure. Figure 2 and attached Figure 3 In the above embodiment, when working, the motor 4 inhales air from the air inlet 110, reduces the moisture in the air through the evaporator 2, and then releases heat through the condenser 3 to increase the air temperature to form thermal energy. The graphene far-infrared heating plate 5 then transfers the heat energy to the drying drum 6 through the drying port 120 by far-infrared radiation to dry the crops to be dried in the drying drum 6. In the embodiment, the motor 4 is made of copper or stainless steel. This embodiment combines the cooling and heating functions of the evaporator 2 and the condenser 3 with the radiation heating technology of the graphene far-infrared heating plate 5 to achieve efficient and uniform drying of crops without manual turning, greatly improving the drying efficiency and the drying quality of crops, and has the advantages of fast heating speed and high thermal efficiency.

The heat energy passes through the connecting port 810 and enters the upper space 130.
