Problems solved by technology

[0005] The existing pre-liming process is relatively short, the reaction between lime milk and organic acid in cane juice is not complete, and the instantaneous over-alkali causes a large amount of reducing sugar to decompose and increase the pigment

Embodiment Construction

[0033] The present invention presents many applicable inventive concepts that can be embodied in numerous specific contexts. The specific examples described in the following embodiments of the present invention are only used as illustrations of specific embodiments of the present invention, and are not intended to limit the scope of the present invention.

[0034] The invention provides a sugarcane preash pressing process, such as figure 1 The following steps are shown: 1100) crushing: crushing sugarcane raw materials to obtain crushed sugarcane material; 1200) adding ash to the sugarcane material: spraying lime milk into the crushed sugarcane material to adjust the pH value of the sugarcane material, and mixing evenly to obtain The crushed cane material mixed with lime milk, the amount of lime milk sprayed on the crushed cane material makes the PH of the initial pressed juice of the cane material 8-8.5; The juice is produced, and milk of lime is added to the cane juice to ad...

Abstract

The invention provides a sugar cane preliming pressing technique which comprises the following steps: a) crushing: crushing the sugar cane raw material to obtain a crushed sugar cane material; b) sugar cane material liming: spraying lime milk into the crushed sugar cane material to regulate the pH value of the sugar cane material, and uniformly mixing to obtain a lime-milk-mixed crushed sugar cane material, wherein the quantity of the lime milk sprayed into the crushed sugar cane material enables the pH value of the initially pressed juice to be 8-8.5; and c) cane juice liming: pressing the lime-milk-mixed crushed sugar cane material to obtain juice, and adding lime milk into the cane juice to regulate the pH value to 10.5-11. The progressive liming technique can enhance the pressing liming reaction effect, and also gives consideration to the disinfection and sterilization in the pressing stage. The technique promotes the improvement of the product quality, lowers the microbial transformation loss, and enhances the recovery of sugar.

Description

technical field [0001] The invention relates to a sugar cane sugar making process, in particular to a sugar cane preash pressing process. Background technique [0002] In the process of sugar cane sugar production, it is generally necessary to crush the sugarcane material into cane shreds, and then use a press to squeeze out the juice for many times, and mix the cane juice obtained by multiple pressing, and clean the mixed juice. Through the solid-liquid separation method, as much as possible Various non-sugar substances that affect the crystallization of sucrose in the mixed juice are removed, and a clear and purer clear juice with a lower color value is obtained. [0003] The lime method can be used in the cleaning treatment of sugarcane juice, which uses lime as the main cleaning agent. Pre-ash the mixed juice to pH 6.4, heat to 60°C, then add lime to neutralize to pH 7.6-8.0, then heat to 100-102°C, and separate the clean juice and mud juice in a settler. The filtered ...
