Sodium glucoheptonate solid particle drying treatment process and system

Abstract

The invention discloses a sodium glucoheptonate solid particle drying treatment process and system, and the process comprises the following steps: 1, carrying out centrifugal separation on a sodium glucoheptonate mixture; step 2, placing the sodium glucoheptonate solid-liquid mixture on a filter screen; 3, placing the dried sodium glucoheptonate solid particles on at least one layer of screen, and 4, dissolving the sodium glucoheptonate solid particles with overlarge fineness in water for recrystallization, and repeating the steps after the step 1. The sodium glucoheptonate solid-liquid mixture is dried through high-temperature dry steam to form sodium glucoheptonate solid particles, meanwhile, a sodium glucoheptonate solution is screened out, and the sodium glucoheptonate particles with the fineness not reaching the standard are crystallized and refined again.

Description

technical field [0001] The invention relates to a subsequent treatment process of sodium glucoheptonate, in particular to a process and system for drying solid particles of sodium glucoheptonate. Background technique [0002] Sodium Glucoheptonate (sodium D-glycero-D-gulo-heptonate) is a sodium salt of heptanoic acid. Most of the sodium glucoheptonate products on the market are dark amber or brown-red with slight Ammonia-flavored transparent solution, solid content 35%-40%, also available in a small amount of yellow-white or light brown-yellow odorless fine crystalline sodium glucoheptonate dry powder. [0003] In the product of synthesizing sodium glucoheptonate, liquid sodium glucoheptonate and sodium glucoheptonate particles with higher water content are mixed in the product, and the solid-liquid separation is usually performed by centrifugation. The water content in sodium glucoheptonate is relatively high, and it cannot be sold as sodium glucoheptonate crystalline dry ...

Problems solved by technology

[0003] In the synthetic product of sodium glucoheptonate, liquid sodium glucoheptonate and sodium glucoheptonate particles with higher water content are mixed in the product, and the solid and liquid are usually separated by centrifugation, but the separated solid The water content in sodium glucoheptonate is relatively high, so it cannot be sold as sodium glucoheptonate crystalline dry powder, so sodium glucoheptonate needs to be dried
