Description

Technical Field

[0001] The invention relates to the technical field of seed processing, in particular to a high-pressure air seed processing device. Background Art

[0002] Cruciferous vegetables, such as greens, mustard greens, cabbage, radish, etc., are widely loved by consumers because of their rich nutrition and delicious taste, and occupy an important position in my country's vegetable industry.

[0003] Seed dormancy refers to the phenomenon that viable seeds cannot germinate under suitable environmental conditions due to factors of the embryo or seed coat. Dormancy is common in cruciferous vegetable seeds. Newly harvested cruciferous vegetable seeds need to be placed for a period of time to break dormancy before they can be sown to ensure a normal germination rate. The dormancy problem of cruciferous vegetable seeds has resulted in seed companies being unable to sell seeds in a timely manner, and seedling workers and breeders being unable to sow on time. At present, seed companies need to store seeds for a long time in order to break the dormancy of cruciferous vegetable seeds; this method is time-consuming and labor-intensive and requires a large amount of storage space, increasing storage costs. There are differences in the dormancy degree of seeds in different batches, and the uniformity of dormancy breaking is poor, making it difficult to predict the time when they can be sold.

[0004] Seed vigor, or seed robustness, is a key factor in determining seed germination rate, germination speed and stress resistance, and has a vital impact on the yield and quality of cruciferous vegetables. Low seed vigor can lead to problems such as reduced germination rate, weak seedlings and slow growth, which in turn increases agricultural production costs and risks. In actual production, seed companies mostly use traditional seed pretreatment technologies such as chemical treatment to improve the vitality of cruciferous vegetable seeds, but there are often problems such as unstable effects, complicated operations or the possible introduction of chemical residues. Summary of the invention

The airflow control system can control the rate of filling the second gas tank from the first gas tank and the pressure in the second gas tank; the above equipment is used to quickly break the seed dormancy and improve the seed vitality. The maximum germination rate of the seeds treated with high-pressure gas is significantly higher than that of the control seeds, and the germination uniformity and germination rate of the seeds treated with high-pressure air are significantly higher than those of the control, and the germination is faster and more uniform, which is convenient for unified sowing. By adjusting the pressure and treatment time of the high-pressure air, the dormancy breaking and seed vitality improvement effects can be accurately controlled to meet the needs of different seeds and agricultural production. The seeds are dried during the high-pressure treatment, which does not affect the quality of the seeds.
