The invention relates to the technical field of fruit and vegetable drying and processing, in particular to a heat pump drying device.

Background technique

In recent years, with the implementation of the poverty alleviation policy, it is the goal of the majority of cadres and farmers to make farmers in poor areas get rid of poverty and become rich. In order to further expand poverty alleviation efforts, give full play to the advantages of local resources, and realize poverty alleviation of farmers' industries, the scale and output of agricultural products planting industry are increasing year by year. The concentrated listing of a large number of agricultural products has brought great difficulties to sales. Drying is an effective method for post-production processing of most agricultural products. In order to solve the prominent problems in traditional natural drying, such as long drying time, great influence by climate, poor sanitary conditions, and difficulty in guaranteeing product quality, fruit and vegetable drying rooms have been widely used in Xinjiang, especially southern Xinjiang. However, the drying room volume and loading capacity of the popular fruit and vegetable drying room are large, and in actual use, there are problems such as uneven drying and high artificial assistance intensity. For this reason, the high-quality rate of dried fruit and vegetable products is not high, and the market competitiveness is weak, which greatly inhibits the enthusiasm of farmers for planting.

The control system is composed of a temperature and humidity sensor, an electric control box and a wind speed sensor. The temperature and humidity sensor is fixed in the middle of the adjacent small fans to monitor and control the temperature and humidity in the drying room. The wind speed sensor is fixed at the lower part of the windshield. It is used to monitor and control the wind speed in the drying room. The control system controls the closing and opening of the heat pump host, the moisture exhaust port and the air inlet according to the temperature and humidity sensor. The control system controls the rotation speed of the large fan and the small fan according to the wind speed sensor.

The feeding cart is located in the middle of the drying chamber, the distance between the feeding cart and the baffle is 20cm-80cm, and the distance between the feeding cart and the door is 20cm-150cm.

The distance between the large fan and the end of the windshield is 50cm-150cm.

The beneficial effects of the invention are as follows: using a heat pump as a heat source and using the internal circulation heat pump drying technology, the heat energy in the air can be converted into the energy required for heating the material, and the zero emission of pollutants is realized, and there is no hidden danger of drying with an open flame. To achieve the purpose of reducing energy consumption, environmental protection and sanitation. A number of small fans are evenly distributed on the windshield, and there is a certain space between the feeding car and the small fan and between the feeding car and the door to ensure that the air in the drying room is fully mixed and uniform, and the hot air can evenly blow through each Layer the surface of the dried material to achieve the purpose of improving the uniformity of the temperature, humidity and wind speed distribution of the whole machine. The distribution mode of multiple small fans and large fans is adopted to ensure smooth air speed in the drying room and achieve the purpose of improving drying speed. Therefore, the materials dried by the drying equipment of the invention have the characteristics of uniform color, strong fragrance, uniform shrinkage and high yield, which greatly improves the commerciality of the dried materials and has broad application prospects.

Detailed ways

As shown in Figures 1, 2, and 3, a heat pump drying equipment consists of a control system, a heat pump host 2, an air inlet 3, a small fan 4, a material truck 5, a moisture exhaust port 6, a wind baffle 7, a large fan 8, and a fan. Road 9, room 11 and other components. The air baffle 7 divides the drying chamber 10 into upper and lower parts; the small fan 4 and the feeder 5 are located at the lower part of the air baffle 7; the small fans 4 are evenly distributed on the baffle 15, and the number of the small fans 4 is 6 or 9 Or 12; the feeder 5 is located in the middle of the drying chamber 10, the distance between the feeder 5 and the baffle 15 is 20cm-80cm, and the distance between the feeder 5 and the door 12 is 20cm-150cm; the large fan 8 is fixed on the upper part of the windshield 7 , the distance between the large fan 8 and the end of the windshield 7 is 50cm-150cm; the heat pump host 2 is connected to the room body 11 through the air duct 9 and the air inlet 3; the moisture exhaust port 6 is located on the top of the room body 11; The sensor 14, the electric control box 1 and the wind speed sensor 13 are composed. The temperature and humidity sensor 14 is fixed in the middle of the adjacent small fans 4 to monitor and control the temperature and humidity in the drying room 10. The wind speed sensor 13 is fixed on the windshield 7. The central position of the lower part is used to monitor and control the wind speed in the drying chamber 10. The control system controls the closing and opening of the heat pump host 2, the moisture exhaust port 6 and the air inlet 3 according to the temperature and humidity sensor 14. The control system controls the air speed sensor 13. The speed of the large fan 7 and the small fan 4.

Working principle: evenly place the dried materials on the feeder 5, turn on the heat pump drying equipment, and set the drying process according to the material characteristics. When the temperature in the drying chamber 10 is higher than the set temperature, the heat pump host 2 stops working, and When the temperature in the drying chamber 10 is lower than the set temperature, the heat pump host 2 continues to heat, and so on until the drying ends. When the humidity value in the drying chamber 10 is higher than the set humidity value, the moisture exhaust port 6 and the air inlet 3 are opened at the same time, the hot and humid air in the drying chamber 10 is discharged from the moisture exhaust port 6, and the fresh air enters the drying chamber through the air intake port 3. In the chamber 10, when the humidity value in the drying chamber 10 is lower than the set humidity value, the moisture exhaust port 6 and the air inlet port 3 are closed at the same time until the drying ends. Similarly, when the wind speed value in the drying room 10 is lower than the set wind speed value, increase the rotational speed of the small fan 4 and the large fan 8; when the wind speed value in the drying room 10 is higher than the set wind speed value, reduce the small fan 4 and the large fan 8 The speed of the large fan 8 until the end of drying.

The specific drying process is as follows: the heat pump host 2 absorbs the air in the natural environment, turns into higher temperature air after running through the compressor, and sucks it into the drying chamber 10 through the air inlet 3 under the action of the small fan 4, and enters the drying chamber 10. After the air in the chamber 10 is evenly blown through the feeder 5 under the action of the small fan 4, it returns to the heat pump host 2 through the air duct 9 under the suction of the large fan 8, and thus circulates to form a circulating air until the end of drying. When drying is completed, turn off the heat pump drying equipment, take out the tray and collect, bag and store the dried materials.

The specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or modifications derived from the present invention are still within the protection scope of the present invention.
