Syrup clarification method

Abstract

The invention relates to a syrup clarification method, belonging to the technical field of syrup clarification of the sugar industry. The syrup clarification method is used for clarifying the syrup by use of a syrup air flotation clarification and membrane separation coupling technology and comprises major processes of treating in a syrup air flotation clarification pretreatment system, a syrup air flotation clarification system and a syrup membrane separation system, and specifically comprises the following steps: performing air flotation clarification pretreatment on the syrup first, namely filtering the syrup with a filter screen, adding lime and phosphoric acid to adjust the pH value, and performing primary heating treatment; after the treatment, treating the syrup in the air flotation clarification system, and removing the non-sugar components of the network in the syrup; treating the syrup obtained by the air flotation clarification with a syrup filtering system; and clarifying in the efficient syrup membrane separation system to obtain clear syrup of which the clarification quality is not lower than that of the traditional sugar production technology to finish the syrup clarification process. The process provided by the invention mainly adopts the air flotation clarification and membrane separation coupling technology; the method is simple and advanced, the retention time of the syrup is short, the sucrose loss is little, the clarification is stable and controllable, the clarification efficiency is high, and the method is an effective measure of a sugar refinery for realizing energy-saving and clean production and implementing sustainable development and has a relatively good application prospect.

Description
