Background
With the rapid increase of the demand and supply requirements of the market and the increase of the planting scale of agricultural products, the yield of the agricultural products is continuously improved. For agricultural products such as potatoes, sweet potatoes and the like which grow in the ground, after the agricultural products are dug out, corresponding matched treatment procedures such as cleaning, impurity removal, disinfection, drying, packaging and the like are needed, and then the agricultural products can flow into the market for people to purchase. At present, the large-scale picking process of a plurality of agricultural products is basically automated, and the agricultural products with large workload and heavy tasks can be treated by a machine instead of manpower, so that the workload of people is reduced to a certain extent, the labor cost is saved, and the efficiency is improved. However, the machine picking only completes the primary treatment process of the agricultural products, and the subsequent related processes still need manual support to be carried out. Taking crops such as sweet potatoes, potatoes and the like as an example, a large amount of dust can be attached to the crops during picking, and then manual cleaning and impurity removal are needed, but because the crops are required to be in a low-temperature drying environment as much as possible during storage, the crops need to be further subjected to moisture removal and drying, and finally products with good selling quality are obtained through relevant processes and are distributed in the market.
At present, for the soil crops such as potatoes and sweet potatoes, the common cleaning process is to manually wash the soil crops by water or to directly dry the soil crops by a brush, the water is not involved, the soil crops directly flow into the market after being treated to a certain degree, and the agricultural products are prevented from going bad and rotten in the washing process. For the rest of the agricultural products, many also require water washing to remove the insect eggs and pesticide residues on the surface. The washed agricultural products are generally selected to be dried, and can flow into the market after the moisture is dissipated to a certain degree, and meanwhile, the moisture can play a certain role in keeping fresh. Certainly, some automatic agricultural product cleaning devices are also available in the market at present, the internal principle and structure of the automatic agricultural product cleaning devices are similar to those of common washing machines, and the automatic agricultural product cleaning devices are stirred by a machine to generate friction so as to remove dirt on the surfaces of agricultural products, or high-pressure spray water or high-pressure air and the like are added into the automatic agricultural product cleaning devices to clean the agricultural products. Admittedly, the above-described method has certain advantages in cleaning and treating agricultural products. However, the method only aims at a single step of cleaning and impurity removal in the agricultural product treatment process, and meanwhile, most of water brought to the surfaces of the crops by washing is more harmful than beneficial, and the quality of the agricultural products is influenced because the surface water cannot be dried in time.

Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
Referring to fig. 1-12, the present invention provides a technical solution:
the invention utilizes the cold energy provided by the heat pump to prepare the ice sand, the ice cone and the dry hot air, which are used for cleaning agricultural products and drying the agricultural products, and is mainly based on the following principle:
(1) the heat pump technology comprises the following steps: the principle diagram is shown in fig. 1, the heat pump unit mainly comprises a compressor 1, a condenser 5, a throttle valve 14 and an evaporator 62, the compressor 1 is a main work-doing component, and the throttle valve 14 is a throttling pressure-reducing device. The main working flow of the heat pump unit is as follows: in the compressor 1, low-temperature and low-pressure gaseous refrigerant is compressed, the temperature and the pressure are increased, the refrigerant is changed into high-temperature and high-pressure gaseous refrigerant, the high-temperature and high-pressure gaseous refrigerant flows into the condenser 5, the condenser 5 is a heat exchanger, the inside of the condenser is mainly coiled by an S-shaped copper pipe, and fins are generally attached to the outer wall of the copper pipe so as to strengthen the heat exchange capacity of the condenser 5. After the high-temperature high-pressure gaseous refrigerant flows through the condenser 5 with lower temperature, the phase state transformation can occur, the high-temperature high-pressure gaseous refrigerant is changed into a high-pressure low-temperature liquid refrigerant (the low temperature of the high-pressure low-temperature liquid refrigerant is relative to the temperature of the refrigerant when the refrigerant leaves the compressor 1), heat is released after the high-temperature high-pressure gaseous refrigerant is liquefied, so that the outer wall of a copper pipe of the condenser 5 generates heat, the temperature is increased, the heat is dissipated in time through fins and a fan arranged in the condenser 5, and the heat. After passing through the condenser 5, the refrigerant becomes a high-pressure low-temperature liquid refrigerant, and is throttled and depressurized through the throttle valve 14, and the phase state of the refrigerant is not changed at this time, but the pressure is reduced, so that the gasification pressure is reduced, and the gasification process is facilitated to occur inside the evaporator 62. The low-temperature and low-pressure liquid refrigerant flowing through the throttle valve 14 flows into the evaporator 62, absorbs heat of the evaporator 62, and is gasified to become a low-temperature and low-pressure gaseous refrigerant. The evaporator 62 is also a heat exchanger, and the inside thereof is also an S-shaped copper pipe coiled structure, so that after the refrigerant absorbs the heat of the evaporator 62, the temperature of the evaporator 62 is reduced, and the cold of the evaporator 62 is taken away by a fan inside the evaporator 62 or an external cooling water, and the cold is the refrigerating capacity of the evaporator 62 of the heat pump unit. The refrigerant flowing through the evaporator 62 is changed into a low-temperature low-pressure gaseous refrigerant from a low-temperature low-pressure liquid refrigerant, then enters the compressor 1 again for compression, is changed into a high-temperature high-pressure gaseous refrigerant, and is subjected to the next refrigerant circulation flow, so that the heat pump unit forms continuous refrigeration and heating, continuous ice making sand and dry hot air are realized, and a series of functions of the equipment are realized.
(2) Hot air drying and circulating dehumidification technology: after the agricultural products are washed by the ice sand, moisture is attached to the surfaces of the agricultural products, and the agricultural products are deteriorated in advance due to excessive moisture, so that the transportation and the storage are influenced, and therefore, the agricultural products need to be dried. The heat pump technology can be used for preparing hot air with higher temperature, the hot air is conveyed to the agricultural products to be dried in an even airflow mode, and moisture on the surfaces of the agricultural products is promoted to be transmitted into the hot air flow through sensible heat exchange and latent heat exchange, so that the drying purpose is achieved. The temperature of the hot air after drying may be reduced, but its relative humidity may be increased, thereby limiting its ability to be further dried, i.e., the resistance to mass transfer of moisture to the air increases. At this moment, fresh hot dry air is needed for supplement, and the hot humid air with lower drying capacity is exhausted. Because the hot and humid air has a certain sensible heat recovery potential, the hot and humid air can be liquefied and dehumidified after passing through the low-temperature ice sand cleaning equipment, and then can be recycled, so that the cyclic drying and dehumidifying processes of the hot and dry air and the hot and humid air are realized. The process is very important for drying the agricultural products, and the drying efficiency is higher than that of the conventional natural drying, so that the operation is more facilitated.
(3) The multi-point balance heat exchanger sensible heat recovery technology comprises the following steps: the principle schematic diagram is shown in fig. 2, after the agricultural products are dried, hot and humid air with higher temperature can be discharged from the drying box, the hot and humid air still has a certain sensible heat recovery value, and sensible heat can be effectively recovered by utilizing the multipoint balance heat exchanger. The multipoint balance heat exchanger is of a sandwich structure, a thin pipe is nested in the multipoint balance heat exchanger, a cavity is formed outside the thin pipe, and a relatively thick pipeline is arranged on the periphery of the cavity. The hot and wet air with higher temperature passes through the tube pass, the dry air with lower temperature passes through the shell pass, the counter-flow heat exchange is formed, under certain heat exchange time, namely under an ideal condition, the temperature at the outlet of the high-temperature dry air 117 is considered to be equal to or very close to the temperature at the inlet of the high-temperature hot and wet air 118, so that the purpose of transferring the sensible heat of the high-temperature hot and wet air 118 to the high-temperature dry air 117 is achieved, and the dry air with higher temperature is utilized and further heated by the condenser, so that the dry and hot air meeting the drying requirement of agricultural products can be obtained. After the dry hot air dries the agricultural products, the high-temperature hot humid air 118 is obtained continuously, so that the heat of the fresh supplemented low-temperature dry air 116 can be taken away through the multipoint balance heat exchanger, sensible heat exchange is completed, a series of processes such as multipoint balance heat exchange and drying of the next process are carried out, and the low-temperature hot humid air 119 is discharged finally. The main purpose of introducing the multipoint balance heat exchanger is to recover sensible heat, thereby ensuring the maximum energy utilization efficiency of the equipment and simultaneously achieving the optimal operation state.
(4) The technology for cleaning the ice sand and recycling ice water resources comprises the following steps: by utilizing the refrigerating capacity of the evaporator section, when the power consumption of the heat pump unit is larger, lower temperature can be obtained, and more cold energy can be prepared. The copper tubes of the evaporator are placed on the peripheral wall surfaces of the ice making groove, so that the water in the ice making groove fully absorbs the cold energy of the water and the temperature of the water is reduced to reach the ice water phase change temperature point, and the function of preparing the ice sand and the ice cone is formed. Compared with conventional cleaning equipment, the equipment mainly utilizes the ice sand, the ice cone and the added part of water, so that the friction force is larger, and the cleaning effect is better. Meanwhile, after the ice cone is cleaned, water resources can be reused through measures such as filtering and precipitation. The cleaning of agricultural products is realized by utilizing the phase change process of water, other pollutants can not be generated, the effect can be better, and the deep treatment of attachments on the surfaces of the agricultural products such as silt can be achieved.
