To expedite the settlement of post-harvest losses of farm produce serious problems, the beginning of the full implementation of the state to subsidize agricultural products processing facilities. Recently, the Ministry of Agriculture and Ministry of Finance jointly issued "on efforts to early 2014 the implementation of the agricultural produce processing notice" was promulgated. Among them, the subsidy standard drying facilities is 30%, which is applied to the heat pump drying and expansion will play a great role in promoting, but also will promote the development of air heat pump industry. It is understood that, in order to improve the conditions of primary processing of agricultural produce, reduce post-harvest losses, a balanced market supply and stabilize prices, increase farmers' income, improve the quality and safety of agricultural products, the central government allocated "Agricultural Science and Technology Extension and Service achievements grant funds" support for agricultural production and processing facilities beginning. "About to do primary processing of agricultural produce in 2014 the implementation of the notice" requirement, this year the central government will arrange 600 million yuan subsidy origin of agricultural products processing facilities beginning subsidy standard is 30%, ranging from subsidies for each of the new potato storage cellar, fruit and vegetable preservation library and drying facilities and other three categories 19 kinds of specifications of primary processing of agricultural production facilities. In recent years, as China's growing demand for agricultural clarified the role of the drying equipment in the industry is also growing. Air can be used as a new, energy-efficient new technologies, in large measure to solve the problem of low efficiency of conventional drying and high drying costs problems. To send Ottawa research and development of high temperature heat pump air dryer, for example, which has energy conservation, safety and environmental protection, drying effect, high efficiency, low operating costs, labor costs and other savings and wide range of advantages, by industry praise. In addition, high temperature heat pump dryer used in the drying process, the main principle is to use a heat pump evaporator absorbs ambient heat in the air, or recovering exhaust heat drying process, acting through the compressor, the energy transport (transfer) to drying oven, hot air drying chamber through repeated cycles of heating, the absorption material in the water, its own cooling humidification, humidity or condensation process after hot water removal, the material in the water is discharged away and ultimately Continuous dry materials. And widely used in tobacco drying, drying agricultural products, dried herbs, crafts drying, plating drying, dried seafood, dried fruits and vegetables, dry cured products, and other fields. As an energy efficient products, compared with conventional drying equipment, energy-saving effect of significantly higher quality of materials drying out.
