Natural plant pigment extraction process

Abstract

The invention discloses a natural plant pigment extraction process, which comprises the steps of soaking, crushing, rolling, filtering, concentrating, drying, and powder making to finally obtain pigment powder, wherein soaking, crushing, rolling and filtering are all completed in a pigment extraction all-in-one machine so as to greatly improve the production efficiency and achieve automatic operation and continuous production, the pigment extraction all-in-one machine is soaked before cleaning to effectively separate and remove harmful residual substances on natural plants so as to greatly improve the cleaning effect and efficiency of the natural plants, multiple times of cyclic crushing treatment can be achieved in a crushing area so as to completely extract the pigment, a rolling and discharging area can continuously conduct rolling and juice discharging in a conveying and moving process so as to achieve complete extraction, and an impurity filtering area can achieve the filtering effect while can further crush substances which cannot be filtered, so that the substances can be completely utilized, and the utilization rate is maximized.

Description

technical field [0001] The invention belongs to the technical field of pigment extraction, in particular to a natural plant pigment extraction process. Background technique [0002] A pigment is a raw material that imparts a certain color. People often choose products by sight, touch, smell and other senses, and pigment is an important part of vision, so whether the pigment is used properly also plays a decisive role in the quality of the product. Synthetic pigment food coloring pigments made from chemical synthesis are called synthetic pigments. Inorganic pigments Commonly used inorganic pigments include iron oxide, carbon black, chromium oxide green, etc. They have good light resistance and are insoluble in water. Natural pigments Commonly used natural pigments include annatto, cochineal, chlorophyll, curcumin, and carmine. [0003] With the improvement of people's quality of life, people pay more attention to pure natural and harmless while pursuing aesthetic feeling. ...

AI Technical Summary

Problems solved by technology

[0003] With the improvement of people's quality of life, people pay more attention to pure natural and harmless while pursuing aesthetic feeling. The equipment cost involved in the existing natural plant pigment extraction process is high, manual extraction is time-consuming, laborious, inefficient, and the extraction is not enough complete, serious waste of raw materials, in order to solve the above problems, a natural plant pigment extraction process is proposed
