High-use-ratio manufacturing technology of extracting highly-active agarose product from red algae

Abstract

The invention discloses a high-use-ratio manufacturing technology of extracting a highly-active agarose product from red algae. The low-alkali pressurizing method is adopted to pretreat the algae, so that the agaropectin extraction rate is effectively increased, and the high-alkali consumption is reduced; a multi-stage vibrating screen secondary agaropectin extraction technology is developed to increase the agaropectin extraction rate, and the residue is modified and processed to form manure or a feed additive, so that the comprehensive use rate of the red algae is greatly increased; a filter system, a novel band drying system, a full-automatic strip drying system for strip agar, a high temperature dry heat sterilization system and other novel integrated large-scale manufacturing devices are developed, so that the problems of high energy-consumption and lag in production technique in the actual production process are solved accordingly.

Description

technical field [0001] The invention relates to a production process of agar, in particular to a high-utilization production process for extracting high-activity agarose products from red algae. Background technique [0002] Agar, scientific name agar, also known as agar, jelly powder, agar, etc., is a polysaccharide colloid extracted from red algae, a marine resource. It is widely used in biotechnology, medicine, food, daily chemical and other industries. The use of agar in food can significantly change the quality of food and improve the grade of food. It is characterized by coagulation, stability, and the ability to form complexes with some substances and other physical and chemical properties. It can be used as a thickener, coagulant, suspending agent, emulsifier, preservative and stabilizer. Agar can be used as culture medium, ointment base and other purposes in chemical industry and medical scientific research. [0003] At present, there are many manufacturers of aga...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many manufacturers of agar in China, and they generally use traditional processing methods. Most of them use the traditional process of soaking in alkali→bleaching→acidification→boiling gelatin to process. The strong alkali, strong acid and chloride ions that need to be used are serious. "Triple" pollution, high cost of sewage treatment, high environmental cost

At the same time, small workshops are produced on a large scale, and the production equipment is backward. For example, the conventional filter box and the traditional hot air drying system have problems such as large energy consumption, low production capacity, and low degree of integration.

Although the agar industry generally presents a situation of considerable profits and short supply, the development of my country's agar processing industry is restricted by various aspects such as backward production technology, serious environmental pollution discharge, and low comprehensive utilization rate.
