Liquorice seed automatic processing method

Abstract

The invention discloses a liquorice seed automatic processing method, which comprises the steps of seed pretreatment, clean selection and fine selection, foam sulfuric acid preparation, seed stirring,seed drying and seed coating. The method has the beneficial effects that the liquorice seeds are treated by an automatic processing flow line; the work efficiency is improved by 600 percent; the labor and material investment is greatly reduced; the production cost is reduced. The liquorice seeds are treated by the automatic processing flow line; the seed purity degree reaches 99 percent; the spread of invasive insect weeds can be effectively prevented; the prevention and removal cost of insect and weeds can be reduced; after the liquorice seeds are treated by the automatic processing flow line, the treated seeds are regular and uniform; the commodity is good; in the hard core eliminating link of the liquorice seeds, foam acid is used for treating the seeds; after the liquorice seeds are treated by foam acid, the seed activity is improved; the liquorice seeds treated by sulfuric acid uses a high-pressure water gun in a seed cleaning machine for fast flushing; the seed processing imbibition, imbibition damage and mechanical imbibition can be effectively prevented; the seed activity is maintained to the maximum degree.

Description

technical field [0001] The invention relates to the technical field of medicinal seed processing, in particular to an automatic processing method for licorice seeds. Background technique [0002] Glycyrrhiza licorice is extremely wild. Under natural wild growth, licorice will bloom and set seeds in the third year, and the hardening rate of the seeds can reach 85%. At present, licorice seeds have not been cultivated for production. Seeds are sown in a natural state, and the emergence rate is quite difficult. It takes 3-5 years to germinate in the soil, and the emergence rate is less than 15%. Therefore, wanting to develop artificial cultivation of licorice, researching licorice seed treatment technology is the first major difficulty. The licorice pods are collected in the natural environment, and the seeds are collected by tapping with wooden sticks or rolling with stones. The seeds are of low purity and mixed with various living or non-living impurities, which is not conduc...

AI Technical Summary

Problems solved by technology

Seeds are sown in a natural state, and the emergence rate is quite difficult. It takes 3-5 years to germinate after being buried in the soil, and the emergence rate is less than 15%.

In recent years, with the implementation of the project of returning farmland to forest and grassland and the urgent demand for commercial licorice in the market, the artificial planting area of ​​licorice has continued to increase, the market demand for high-quality licorice seeds has increased, and the price has soared all the way. Those who lack licorice seed processing machinery and mature treatment technology lead to the death or waste of most high-energy licorice seeds. Therefore, it is an important task to study the automatic processing technology of licorice seeds and improve the efficiency of seed processing to ensure the safety of processing machinery and operators. very important task
