Special high-purity sodium diacetate production line device and operation method

Abstract

The invention relates to the field of chemical industry production automation, and particularly relates to a special high-purity sodium diacetate production line device and an operation method. According to the device and the method, a reaction kettle, a stirring refrigerator and a dry product material bin are connected with one another by a connecting pipe; the main production steps are carried out in the reaction kettle; the production method is simple; the device automation degree is high; the production efficiency is improved effectively; a manpower resource is reduced so as to reduce the safety hazard; moreover, an obtained crystallized product is uniform in particle, and is good in dispersibility; the production method is simple; raw materials are available; the production cost is low; 'three wastes' (waste gas, waste water and industrial residue) are not discharged in the reaction process, and the operation is simple. The reaction has favorable reaction selectivity and safety, and the produced sodium diacetate has the pure white appearance, is ordered in crystallization, is high product purity, and is stable in quality.

Description

technical field [0001] The invention relates to the field of chemical production automation, in particular to a special production line device and operation method for high-purity sodium diacetate. Background technique [0002] Sodium diacetate is a multifunctional edible chemical, mainly used as preservative, antifungal agent, chelating agent, flavoring agent, PH regulator, meat product preservative in food and feed industry, and it is also a compound antifungal agent. main ingreadient. It has the functions of high-efficiency anti-mold, fresh-keeping, and increasing nutritional value. It is not only suitable for safe storage of grain seeds, but also suitable for anti-mold and fresh-keeping of feed, increasing nutritional value, and improving palatability. It is especially suitable for fresh-keeping of corn and grains. At present, the large-scale production of sodium diacetate at home and abroad mainly includes sodium acetate-acetic acid method, acetic acid-acetic anh...

AI Technical Summary

Problems solved by technology

[0003] In the traditional sodium diacetate preparation process, the degree of automation is low, and operators need to control it in real time. In order to completely increase the purity of the product, it is often necessary to use a large number of human resources to be responsible for repeated purification, equipment control and product inspection. This reduces the production profit margin of the enterprise and increases the safety hazard
