Description

technical field [0001] The invention relates to the field of new energy agricultural product drying equipment, in particular to a high-temperature solar air energy heat pump heating device for an agricultural product drying box. Background technique [0002] Since the reform and opening up, especially since the new century, my country's agricultural product processing industry has developed rapidly, and the agricultural product processing industry has become one of the most dynamic industries in the national economy. When the drying of agricultural products is not complete, it is easy to produce mildew in the process of storage and transportation, resulting in losses. In my country, the annual post-harvest loss of grain due to mildew reaches 25-33 billion catties, and the annual post-harvest loss of agricultural products due to mildew reaches 8000. tons, with a total loss value of nearly 80 billion yuan. All use of electric drying or coal heating will result in high energy c...

AI Technical Summary

Problems solved by technology

All use of electric drying or coal heating will result in high energy consumption and a substantial increase in cost. Some of them use new energy for heating and drying, but the technology is not mature enough. First, the temperature is not high enough to result in insufficient drying of agricultural products. Second, The reason is that the utilization of heat energy by new energy is not high enough, resulting in a small scale and low drying capacity; the third is the problem of poor drying uniformity

Long drying time increases energy consumption, leading to higher processing costs of agricultural products
