Automated Extraction Process of Carrageenan

Abstract

The invention discloses an automatic extracting method of carrageenan. According to the automatic extracting method, carrageenan is obtained via smashing, alkali treatment, water washing, gum cooking, filtering, salting out precipitating, press filtering, strip cutting, and crushing of seaweed. The automatic method comprises following steps: seaweed raw material is delivered into a raw material tank, and is delivered through a material smashing device, an alkali treatment device, a gum cooking device, a first frame and plate filtration machine, a second frame and plate filtration machine, a filter press, a strip cutting device, and a pulverizer successively. In a production line, the material smashing device is arranged on the upper part of the alkali treatment device, so that the raw material obtained via smashing in the material smashing device is delivered into the alkali treatment device under gravity effect, energy consumption and labor intensity are reduced, and high efficiency production and environment protection are realized.

Description

technical field [0001] The invention relates to the technical field of separation and extraction of active ingredients of natural products, in particular to an automatic extraction process of carrageenan, the entire preparation process of which realizes automatic production and greatly improves production efficiency. Background technique [0002] Carrageenan is one of the three types of alginate, also known as carrageenan, staghorn alginate, and Irish vegetable gum. Obtained; its yield is second only to alginate, and it has attracted much attention due to its excellent properties and wide application. [0003] The reactivity of carrageenan mainly comes from the half ester sulfate group on the galactose residue, which has strong anionic activity and is a typical anionic polysaccharide. Food-grade carrageenan is white or light yellow, wrinkled, slightly glossy, translucent flakes or powder, odorless or slightly smelly, tasteless, sticky and slippery, soluble in hot water abov...

AI Technical Summary

Problems solved by technology

[0006] In the current carrageenan production process, the existing production equipment is mostly small-scale equipment, its production efficiency is low, the degree of automation is low, it requires a large labor intensity to cooperate with equipment production, and it cannot effectively treat the waste water generated in the production process, resulting in production Difficult to scale up and difficult to guarantee product quality
