中共中央办公厅、国务院办公厅近日印发《关于加快构建政策体系培育新型农业经营主体的意见》，第一次明确提出了支持新型农业经营主体发展的政策框架。近年来，虽然新型农业主体发展迅猛，但与此同时也面临前所未有的困难。一方面，由于大宗农产品价格下行，经营主体收入下降；由于成本刚性上涨，经营主体负担较重；由于农业基础设施欠账多，靠经营主体自身投入难以承担；特别是信贷保险、设施用地、人才引进等方面面临的问题较为突出。另一方面，有的新型农业经营主体带农助农能力不够强，与农民的利益联结不够紧，自身运作不够规范等问题也还存在。

The demand for more energy-efficient dryers (for fruits, vegetables, nuts, and herbs) that can handle a variable load, are multi-purpose, automated, smart, and integrated with multi-functionality like peeling, grating, or cutting, is increasing. Additionally, for drying heat-sensitive raw materials, the focus is shifting from freeze-drying to more economical technologies. To achieve this, players operating in this space are coming up with hybrid or combination technologies that can help reduce cycle time and increase energy efficiency, while still maintaining a high quality of the dried products. However, the industry is highly fragmented with the top five players comprising less than 10% of the market share globally in terms of value, and they compete on the basis of technological innovation and advancements. Players leverage highly on their distribution network, contract relationships, and location advantage to supply heavy and large equipment. Players continue to look for more avenues and additional revenue streams to remain profitable in the market.
