Description

Technical Field

[0001] The invention relates to the technical field of seed drying, in particular to a method and equipment for drying beet seeds. Background Art

[0002] Generally, the moisture content of newly harvested seeds is as high as 25%-45%, and the respiration intensity is high, which releases a lot of heat and moisture. The seeds are prone to heat and mildew, or poisoned by alcohol produced by anaerobic respiration, or die from freezing damage at sub-zero temperatures. When the moisture content of seeds is above 40%-60%, the seeds will germinate. High-moisture seeds are conducive to the activity and reproduction of pests in warehouses, which endangers the storage of seeds. Therefore, it is necessary to dry the seeds in time to reduce the moisture content of seeds to a safe level for safe packaging and storage to ensure the stability of seed storage.

[0003] Unlike the seeds of other crops, the calyx and pericarp on the outside of beet seeds are composed of thick-walled dead cells, which are hard, lignified, and rough. This results in slow germination of beet seeds, poor uniformity of emergence, and the need to absorb a large amount of water. Seed priming is a new seed pre-sowing treatment technology that can repair damage to subcellular structures caused by deterioration and promote the development of immature seeds to physiological maturity, thereby improving the germination rate and stress resistance of seeds and uniformity of emergence. However, liquid priming is often used in beet production, and the seeds need to be dried after priming. Different drying times have a significant effect on the priming effect of beet seeds. Therefore, it is necessary to develop a special drying equipment for beet seeds to improve the priming effect. Summary of the invention
