Quick cleaning equipment and method of gracilaria gigas harvey sodium hypochlorite solution

Abstract

Disclosed is a fast gracilaria sodium hypochlorite solution washing device and the method. The method includes the following steps: blanch the gracilaria in a bleacher which can be fed with water and drain water quickly, keep the water draining and feeding for 40-60 seconds each time, then drain the sodium hypochlorite solution immediately and feed water to the bleacher through a water storage tank in the way of bounce-back and clean the bleacher from above the bleacher in the way of spraying. In this way, the gracilaria at the lower part of the bleacher, which is greatly exposed to sodium hypochlorite solution, can be effectively washed away, so that the gracilaria can be totally and smoothly washed away, ensuring the blanching effect of the gracilaria so as to improve the extraction yield and the gel strength of the product agar. After blanching, the gracilaria is increased in intact rate, and the extraction yield and the geling strength are respectively increased by 7% and 11%. Forone thing, the fast washing shortens the time of the blanching procedure in which the gelling strength is most easy to be damaged, thus ensuring quality stability of the product; for another thing, the invention improves enterprise economic benefits, thus the invention is easy to be popularized for application.

Description

technical field [0001] The invention belongs to the field of aquatic product processing, in particular to a quick cleaning device and method for Gracilaria bleaching solution. Background technique [0002] Bleaching of Gracilaria is an important link in the production process of extracting agar from Gracilaria. Agar production enterprises generally have the problem of not being able to effectively wash off the bleaching solution in a short period of time after bleaching Gracilaria. The bleaching solution composed of chemical substances such as acids and bleaching agents used has great damage to the agarose macromolecules due to its strong acidity and strong oxidative properties. The extraction rate and gel strength of different degrees of decline, seriously affecting the extraction rate and quality of agar products. This problem has become a difficult problem that has not been solved for a long time in the processing technology of Gracilaria, which affects the economic ben...
