Each grinding plate is equipped with an independent cavity to keep the liquid level above the material. Every time it is turned, the pigment leaching rate is improved.

Description

technical field [0001] The invention belongs to the field of pigment extraction, in particular to a multiple extraction device for biological pigments. Background technique [0002] Biochromes are a class of chemicals in living cells. Because of some special chemical structures, they can reflect, interfere, scatter or absorb light, so that biological tissues show different colors. There are many kinds of biological pigments and a wide range of sources. Many pigments in industrial production come from plants and microorganisms; several traditional extraction methods 1. Extraction process: raw material collection, screening, washing and drying, raw material processing, extraction, separation, purification, drying, concentration and productization 2 .Enzyme reaction method produces the desired color through an enzyme reaction. For example: the yellow pigment extracted from the fruit of gardenia is treated with enzymes in food processing to produce gardenia blue pigment and ga...

Problems solved by technology

[0003] However, the current extraction device is single and only relies on physical methods for extraction. The extraction efficiency is low, the production cost is high, and the investment in large-scale production is large; and the traditional grinding mechanism has a high material level and a large solvent penetration resistance. There are adverse effects; the previous extraction equipment lacked temperature control function, and the temperature played an important role in the leaching of pigments. However, in the previous control process, the extraction tank was basically heated directly, and the temperature was unstable, resulting in leaching of pigments. The efficiency varies from high to low, which affects the pigment extraction efficiency; and the extraction form in the existing extraction device is fixed, and the efficiency of repeated extraction is low. Most of the single extractions lead to incomplete extraction of plant pigments and reduce the extraction quality.
