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

Embodiment 1

[0029] The cleaning of the fruit of snow lotus bracts:

[0030] 1. Put the yacon fruit order collected from the field in a drying room with environmental conditions of 15°C and 15% RH to dry to 14% to 16% RH. Prevent aging, decline in vigor level, early germination and other conditions; on the other hand, it helps to improve the processing resistance of the fruit, and makes the bud-leaf snow lotus fruit easy to fall off from the involucral bud, and the pappus at the top is easy to fall off from the fruit. .

[0031] 2. Under the condition of room temperature, thinly lay the fruit order of snow lotus bracts on a stainless steel screen with a diameter of 21.1-21.5cm, a depth of 5.5cm, and a hole diameter of 1.4-2.36mm under the vacuum hood, and gently use a rubber stopper. By rubbing, the fruit is detached from the involucre, separated from the pappus, and falls into the lower stainless steel chassis, while most of the inflorescence residue and pappus remain in the stainless st...

Embodiment 2

[0036] The cleaning of the fruit of other species of Asteraceae (such as snow lotus blunt bud and snow lotus cone):

[0037] 1. Put the fruit order of other species of Asteraceae (such as snow lotus blunt bud and snow lotus ball) collected from the field in a drying room for drying, and the environmental conditions in the drying room are 15 ° C and 15% RH. The fruit order should be dried to 14% ~ 16% RH.

[0038] 2. Under the condition of room temperature, thinly lay the fruit sequence of snow lotus blunt bud or snow lotus ball on a stainless steel screen with a diameter of 21.1-21.5cm, a depth of 5.5cm and an aperture of 1.4-2.36mm under the vacuum hood. The rubber stopper is gently rubbed to dislodge the fruit from the involucre and separate from the pappus into the lower stainless steel chassis.

[0039] 3. Put the fruit with the pappus removed from the chassis, a small amount of the pappus and the residue of the fruit sequence into the seed separator. According to the spe...

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 fruit. Background technique [0002] Saussurea obvallata is a perennial herb of Compositae, 16-60cm high, containing protein, amino acids, flavonoids, alkaloids, etc. It can effectively treat rheumatoid arthritis, altitude sickness, and irregular menstruation. However, the natural resources of snow lotus are very limited. They are only distributed in Gansu, Qinghai, Sichuan, Yunnan and Tibet in China, and only grow in alpine grasslands, rocky hillsides, crevices by streams, and flowing rocks at an altitude of 3200-4700m. In addition, in recent years, it has been indiscriminately excavated by medicinal farmers, and artificial cultivation is more difficult, so it is in urgent need of protection, and it is an important object for major seed (quality) banks to save. [0003] The inflorescence of snow lotus bracts is a capitulum,...
