The vegetable and fruit dehydrator can remove the moisture of vegetables and fruits, and can play a drying role. Invest in the deep processing industry of vegetable dehydration, which is profitable. The proportion of dehydrated vegetables in China's vegetable exports is increasing. Although the output of dehydrated vegetables in China is increasing rapidly every year, and has accounted for a considerable portion of the world's total output, it is estimated that the annual demand gap for dehydrated vegetables in the international and domestic markets is more than 50000 tons. Therefore, the dehydrated vegetables industry is an export industry with rich profits and relatively growth potential. In terms of the current situation, there are six factors that restrict the development of the dehydrated vegetables industry.

　　First of all, although China's output of major agricultural products such as grain, fruit, meat, poultry, eggs, aquatic products and vegetables ranks first in the world, there is still a gap between China and the world in terms of total processing volume and processing level. The ratio of agricultural product processing industry output value to agricultural output value in developed countries is mostly 31, while that in China is only 0. 61； The degree of processing of agricultural products in developed countries has reached 80, while that in China is only 45, of which more than two deep processing accounts for only 20.

　　Secondly, the imperfect management system lacks unified planning, classification guidance and coordination for the guidance and management of the vegetable processing industry, resulting in the problem of separation before, during and after production, and affecting the development of the dehydrated vegetable industry.

　　Third, most of the dehydrated vegetable enterprises are small and weak. There are few large enterprises or enterprise groups with strong competitiveness, high production and operation costs, and unstable product quality.

　　Fourth, the innovation and breeding technology system of dehydrated vegetables is backward, and the variety is single. At present, there are only more than 20 categories and more than 30 varieties of dehydrated vegetables, which is too narrow compared with thousands of vegetable varieties.

　　The fifth is that the processing standards and quality control system are not perfect. The quality and safety indicators such as pesticide residue and veterinary drug residue limit in the product standards are few, which are far from the actual needs of agricultural production and development, and cannot meet the needs of the people for consumption safety.

　　The sixth is that the policy support is not enough in terms of credit, tax, investment, etc. The national support policy for dehydrated vegetable processing industry is relatively small, affecting the enthusiasm of investors and the development of agricultural product processing industry.
