With the nation’s emphasis on energy-saving and environmentally-friendly products and its promotion, China’s air-energy industry has continued to expand rapidly with the help of national policies in just over ten years, and the industry is maturing. Nowadays, besides being widely used in life and industry, air-energy heat pump technology has gradually been applied in agriculture, such as drying of agricultural products. It is understood that, compared with the traditional drying equipment, the air heat pump drying equipment has the advantages of energy saving and emission reduction, safety and environmental protection, good drying effect, high efficiency and energy saving, low operating cost, saving labor costs, wide range of use, etc. To a certain extent, it solves the traditional problems of low drying efficiency and high drying cost, so it is well received by users. At the same time, the air energy heat pump drying equipment can be widely used in tobacco drying, fruit and vegetable drying, medicinal drying, seafood drying, drying of wax products, betelnut drying, etc., and the results are significant. Good policy is frequent to promote the development of air energy heat pump drying industry In order to improve the initial processing conditions of China's agricultural production areas and improve the quality and safety level of agricultural products, the Ministry of Agriculture and the Ministry of Finance have jointly issued a number of drying support policies, such as the “Notice on Doing Good Job in the Initial Processing of Agricultural Products in 2014â€. The subsidy standard for drying facilities is 30%; the “Guidelines for the Implementation of Agricultural Machinery Purchase Subsidies in 2014†pointed out that the milking machine and dryer can be used to increase the subsidy limit to 120,000 yuan. At the same time, local governments have also issued relevant drying subsidy policies based on local market characteristics, such as drying subsidies for luohanguo in Longsheng County, subsidies for drying facilities in Ningxia Hui Autonomous Region, new betel nuts drying in Hainan Provincial Department of Agriculture and the Ministry of Finance. Subsidies for the construction of drying facilities, such as equipment construction subsidies and dryer subsidies for the State Administration of Production Safety Supervision and Administration, have been introduced. These favorable policies have greatly promoted the application and expansion of heat pump drying. As the demand for agricultural and sideline products in our country becomes increasingly clear, the role of dryer equipment in the industry will also grow. Leading brands in the air energy industry led by Tongyi Air Energy will seize the opportunity and innovative technologies to further promote the rapid development of the air energy drying industry. 3 Wheel Electric Cargo Tricycle Xuzhou Hengshang Mechanical and Electrical Co., Ltd. , https://www.hengshangtricycle.com
