Preparation method of pure natural plant extracts

Abstract

The invention relates to a preparation method of pure natural plant extracts, and a plant extract preparation device is adopted and comprises a bottom rack, a preparation box, a partition plate, a cleaning mechanism, a drying mechanism, a sewage collection frame and a material collection frame. The preparation method can solve the following problems in the extraction and preparation process of pure natural plant extracts: a, in the traditional preparation process of the plant extracts, since impurities such as bird droppings, dust and the like usually exist on the surfaces of picked mulberry leaves, the mulberry leaves need to be cleaned before the drying and preparation process of the mulberry leaves, and the traditional methods such as hand washing and soaking have low efficiency and affect subsequent drying operations; and b, in the traditional preparation process of the plant extracts, as water drops are attached to the surfaces of cleaned mulberry leaves, if the mulberry leaves are directly dried, the drying time is prolonged, the drying efficiency is low, the water drops among the leaves are not easy to volatilize, and the drying effect of the mulberry leaves is influenced.

Description

technical field [0001] The invention relates to the field of pure natural plant extracts, in particular to a preparation method of pure natural plant extracts. Background technique [0002] Pure natural plant extracts use plants as raw materials. According to the needs of the final product of extraction, through the process of physical and chemical extraction and separation, one or more active ingredients in plants are directional obtained and concentrated without changing The products formed by the structure of its active ingredients usually obtain pure natural plant extracts by drying, soaking in ethanol, refining and filtering the stamens, leaves and rhizomes of plants. It is used in traditional Chinese medicine products. With the gradual increase of people's trust and dependence on natural products, a large part of plant extracts has been used in health care products and food ingredients. In addition, plant extracts have been used in cosmetics and feed in recent years. ...

AI Technical Summary

Problems solved by technology

[0003] At present, the following problems exist in the extraction and preparation process of pure natural plant extracts: a. During the preparation process of traditional plant extracts, since there are usually sundries such as bird droppings and dust on the surface after the mulberry leaves are picked, It is necessary to clean the mulberry leaves before the drying and preparation process of the mulberry leaves. The traditional methods such as washing by hand and soaking are less efficient and affect the subsequent drying operations. b. During the preparation process of traditional plant extracts, Since there are water droplets attached to the surface of the cleaned mulberry leaves, if they are dried directly, the drying time will increase, the drying efficiency will be low, and the water droplets between the leaves are not easy to volatilize, which will affect the drying effect of the mulberry leaves.
