Compound viscosity reducer and application of compound viscosity reducer in molasses viscosity reduction

Abstract

The invention discloses compound viscosity reducer and application of the compound viscosity reducer in molasses viscosity reduction. The compound viscosity reducer is prepared from, by mass, 88-95% of ammonia water and 5-12% of compound surface active agent. The compound surface active agent is formed by compounding negative ion surface active agent and non-ion surface active agent according to the mass ratio of (0.5-3):1. The negative ion surface active agent is at least one of fatty acid methyl ester sulfonate and seconary alkane sulphonate sodium. The non-ion surface active agent is at least one of methyl glucoside ester, sucrose fatty acid ester and fatty acid monoglyceride. The compound viscosity reducer can effectively reduce molasses viscosity without molasses dilution and heating and acid-base addition. Operation is conducted under the normal-temperature condition, temperature parameters do not need to be strictly controlled, the production energy consumption can be greatly reduced, the viscosity reduction process can be conducted under the normal-temperature condition, and the process is green and causes no pollution to the environment.

Description

technical field [0001] The invention belongs to the technical field of biochemical industry, and in particular relates to a composite viscosity reducer and its application in molasses viscosity reduction. Background technique [0002] Molasses is a by-product of the sugar industry, and its composition varies with sugar raw materials and processing conditions. It mainly contains a large amount of fermentable sugar (mainly sucrose), so it is a good fermentation raw material and can be used as yeast, monosodium glutamate, Substrate or base material for fermented products such as organic acids. [0003] The concentration of dry matter in molasses is high, the sugar content is high, and there are many ash and colloidal substances. In current applications, molasses is often pretreated first. Commonly used molasses pretreatment procedures include processes such as dilution, acidification, sterilization, clarification, and addition of nutrient salts. The treatment process consumes...

Problems solved by technology

In the field of molasses viscosity reduction, non-ionic surfactants such as methyl glucoside esters, sucrose fatty acid esters, and glycerol monofatty acid esters are often used in the crystallization process of sucrose in molasses. to achieve the purpose of sucrose purification, but this crystallization process needs to be cooked at high temperature
