一、太阳能干燥技术研究意义能源是人类社会发展的重要基础资源,生态环境是人类赖以生存的基本条件。节约资源和保护生态环境是我国基本国策,解决“三农”问题是全党和全国人民的工作重心。农产品加工不仅延长农业产业链,也是解决“三农”问题的重要途径;具有增加农民收入、壮大县域经济、转移农民就业三大功能,是国民经济的第一大支柱产业和最具成长活力的产业之一。干燥是农产品加工过程中的一个重要工艺过程,目的是除去农产品中多余的水分,提高原料可溶性物质的浓度,阻碍微生物繁殖,抑制农产品中所含酶的活性,从而使脱水后的农产品便于加工、运输、储藏和使用。
First, the significance of research on solar drying technology Energy is an important foundation for the development of human society resources, ecological environment is the basic conditions for human survival. To save resources and protect the ecological environment is China’s basic national policy. Solving the issue of “agriculture, rural areas and farmers” is the center of gravity for the entire party and the people throughout the country. The processing of agricultural products not only prolongs the agricultural industrial chain, but also serves as an important way to solve the “three rural issues.” It has the three major functions of increasing peasants ’income, expanding the county economy and transferring peasants’ employment. It is the first pillar industry and the most growth of the national economy One of the energetic industries. Drying is an important process in the processing of agricultural products. The purpose is to remove excess water from agricultural products, increase the concentration of soluble substances in raw materials, hinder the multiplication of microorganisms and inhibit the activity of enzymes contained in agricultural products, so that the dehydrated agricultural products are easy to process, Transport, storage and use.
