Film coating storage method and equipment for low-moisture seeds

Abstract

The invention discloses a coating storage method and equipment for low-moisture seeds, and the method comprises the following steps: step 1, putting a parylene material into an evaporation chamber, connecting the evaporation chamber with a cracking chamber through a pipeline, and putting the seeds to be coated into a deposition chamber; 2, vacuumizing the evaporation chamber and the cracking chamber through a first pipeline; 3, the evaporation chamber, the cracking chamber and the deposition chamber are controlled to reach the preset temperature; 4, when the temperature and the air pressure of the evaporation chamber and the cracking chamber reach preset values, vacuumizing the deposition chamber to a preset pressure value through a second pipeline; and 5, closing the first pipeline and the second pipeline, and enabling the cracked parylene gas to enter the deposition chamber through a third pipeline to start coating. According to the invention, the time for exposing seeds in a vacuum environment for a long time can be reduced, and excessive dehydration is avoided.

Description

technical field [0001] The invention belongs to the field of seed storage, and in particular relates to a coating storage method and equipment for low-moisture seeds. Background technique [0002] Good quality seeds are the first condition for a strong plant. Generally, the seeds of crops will go through a period of storage from harvest to sowing. During this period, storage conditions and management levels will directly affect the viability and germination of seeds. Scientific storage methods can prolong the life of the seeds, make them vigorous, and ensure that the crops emerge early, neatly, and robustly; however, if the storage methods are unreasonable, the seeds are prone to mildew, deterioration, and reduced vitality. Monopoly has brought heavy losses to farmers. Therefore, seed storage is an important link in agricultural development. The storage of seeds with low water content mainly adopts dry storage methods, which are divided into ordinary dry storage methods,...

AI Technical Summary

Problems solved by technology

For the coating of dry seeds, vacuum pre-pumping, cryogenic cold trap cooling, and cracking furnace temperature are ready in the pre-pumping and material evaporation stages. It takes a long time until the parylene material evaporates, which causes problems such as excessive water loss when living seeds are exposed to vacuum environments. Affects seed preservation and viability
