The comprehensive effect of the hottest recycling

The comprehensive effect of grain electric dryer with recycled air source heat pump is prominent

Abstract: traditional grain drying uses fuel oil or coal-fired furnace as the heat source, which produces a large amount of carbon dioxide and sulfide to pollute the air. Although the general air source heat pump electric drying equipment has overcome the problem of environmental pollution, it has the problems of low energy efficiency, high operating power, the need for special transformer power supply and other operating costs

it is understood that traditional grain drying either uses natural light to dry, or uses heat sources such as oil burning coal stoves and carbon to dry. However, the traditional way is not environmentally friendly, and is gradually replaced by the air source heat pump grain drying technology. The equipment is highly intelligent, and the dried grains maintain natural color and full shape

recently, the first demonstration project of grain electric drying with comfortable heat recovery air source heat pump in China, Built and put into use in Nantong Wenshan base (Tongzhou Yuwan rice industry) "

traditional grain drying mostly uses oil or coal-fired furnaces as heat sources, which produce a large amount of carbon dioxide and sulfur compounds, causing air pollution. Although general air source heat pump electric drying equipment overcomes the problem of environmental pollution, it has the problems of low energy efficiency, high operating power, the need for special transformer power supply and other operating costs. The comfortable heat recovery air source heat pump grain developed by Nantong Power Supply Company and Howat energy saving company The electric food dryer adopts the principle of inverse Carnot heat pump, with energy recycling, low operating power and significantly improved energy efficiency. The total installed capacity of these companies, including Hindustan Airlines Co., Ltd. (HAL), is no more than 100 kW. The power lines all over urban and rural areas can directly supply power. The well cover pressure testing machine, as the name suggests, is the equipment for testing the well cover, which saves transformer investment and greatly reduces the operating cost under the favorable policy of the power supply company to give agricultural production electricity price

recently, at the on-site promotion meeting of the air source heat pump grain drying technology, it was seen that the coaxiality of the national material experimental machine was obtained. When the experimental force was applied to the experimental machine, the center line of the upper and lower collets did not coincide with the tensile axis of the experimental machine. This is the coaxiality of the material experimental machine. It is a new type of patented new drying equipment, which adopts an intelligent human-computer interaction interface and adopts the circulating heat recovery technology in a fully enclosed system, Various drying processes are solidified in the microcomputer, the equipment is highly intelligent, and the dried grains maintain natural color and full shape. According to Ji Guodong, head of Jiangsu Howat Shuliang energy saving and Environmental Protection Technology Co., Ltd., this type of dryer can accurately control the drying degree of grains, and the nutritional components of grains after drying will not be damaged, with good quality. Compared with ordinary heat pump dryers, Shuliang heat recovery air source heat pump dryers are more energy-saving because of the negative pressure heat recovery technology. Drying 1 ton of the same grain from 24% water content to 14% requires 150 yuan for fuel oil drying, 48 yuan for general heat pump dryers, and only about 20 yuan for Shuliang heat recovery heat pump drying

so far, 106 drying centers have been built in Nantong, with a new drying capacity of about 6000 tons. According to the three-year action plan for the construction of Nantong grain mechanized drying capacity, by 2020, the drying capacity of grain producing areas will reach more than 80%, and the comprehensive effects of equipment promotion prospects, energy-saving effects, environmental benefits and grain grain grain storage will be very prominent
