Cleaning method of saussurea obvallata fruits

Abstract

The invention discloses a cleaning method of saussurea obvallata fruits. The cleaning method includes steps: drying the saussurea obvallata infructescence; using a rubber plug to slightly rub the infructescence on a stainless steel screen net of 1.4-2.36mm in mesh size to enable fruits to shed out from involucre and to be separated from pappus; putting fruits and a small part of pappus mixture in an underframe into a seed separator, selecting to use wind power when rotating speed of a fan is 12-25.46Hz to enable full fruits to be separated from empty fruits, fruits damaged by insects and pappus; manually picking out remaining residue and mixed fruits; using paper bags to pack fruits after being cleaned. The cleaning method is simple and easy to implement and short in needed cleaning time; each of fullness ratio and purity of the fruits after being cleaned can reach 100%, storage space of the fruits in a refrigeratory can be reduced effectively, and convenience is brought to subsequent fetching and using of the fruits. The cleaning method is suitable for cleaning other fruits of the Saussurea DC. and can be used for cleaning other seeds of asteraceae on the condition of changing mesh size of the stainless steel screen net and the rotating speed of the seed separator.

Description

technical field [0001] The invention belongs to the technical field of plant protection, and in particular relates to a method for cleaning snow lotus fruits. Background technique [0002] Saussurea obvallata (Saussurea obvallata) is a perennial herb of Compositae, 16-60cm high, containing protein, amino acid, flavonoids, alkaloids, etc. It can effectively treat rheumatoid arthritis, maladaptation to high mountains, and irregular menstruation. It is a rare and precious Chinese herbal medicine in my country and has a very broad application prospect. However, the natural resources of Saussurea baculata are very limited. In my country, they are only distributed in Gansu, Qinghai, Sichuan, Yunnan and Tibet, and only grow in alpine grasslands at an altitude of 3200-4700m, on rocky hillsides, crevices by creeks, and flowing stones. In addition, it has been randomly excavated by drug farmers in recent years, and artificial cultivation is relatively difficult, so it is in urgent need...

AI Technical Summary

Problems solved by technology

It is difficult to clean Compositae fruit, because the fruit needs to be taken out from the involucre when cleaning, and the ring-shaped pappus at the top will gradually expand as the fruit is taken out, so the volume of the fruit will increase seriously, and a little breeze will It will cause the fruits on the surface to fly around, and the inner fruits are intertwined with each other to form a large group; in addition, the peel of the saussurea saustriae is grassy and thin. If it is not cleaned properly, it will damage the fruit and affect its storage. lifespan, so some seed (plasma) banks adopt the method of directly preserving infructescence without cleaning

However, this method will take up a large storage space in the cold storage; in addition, the bracts of the infructome, hollow and moth-eaten fruits may contain some insect eggs and harmful fungi, which will affect the storage life and preservation quality of the whole yacon fruit , increase the chance of fruit infection with bacteria, and is not conducive to the later use of fruit
