Problems solved by technology

However, due to the clarification process of sulfite method, the pH value is controlled in the neutral range, and sugarcane juice is a complex system, and the colloidal substances contained in it will hinder SO 2 with Ca 2+ Generate CaSO 3 Precipitation reaction, so unavoidable SO 2 Residues in clear juice, in the subsequent cooking process, will be absorbed by sucrose crystals, wrapped into the inside of sugar crystals, resulting in sugar containing SO 2

Embodiment 1

[0024] A sugar cane sugar production process, comprising the following steps:

[0025] Step 1, cleaning, chopping, squeezing and filtering the sugarcane to obtain bagasse and sugarcane juice;

[0026] Step 2. Transfer the bagasse to a temperature of 100°C and a steam pressure of 1-2 MPa for steam explosion. The steam explosion time is less than 0.01s, and the pressure holding time is 1min. After that, the pressure is released to normal pressure every 15s. The total weight of the bagasse released to normal pressure for the first time is 25%, and the bagasse after steam explosion is collected;

[0027] Step 3: Spray the compound enzyme solution on the surface of the bagasse after steam explosion, soak the surface until dripping, keep it for 10 minutes, then mix the sugarcane juice, squeeze and filter to obtain the enzymatic solution, wherein the quality of the compound enzyme solution Fraction 0.8%, the compound enzyme is a mixture of glucosidase, trypsin, amylase, and pectinas...

Abstract

The invention discloses a process for preparing sugar from sugarcane. The process comprises the following steps: step 1, subjecting sugarcane to cleaning, chopping, squeezing and filtering successively so as to obtain bagasse and sugarcane juice; step 2, carrying out steam explosion on the bagasse and collecting bagasse having undergone steam explosion; step 3, sprinkling a compound enzyme solution onto the surface of the bagasse having undergone steam explosion so as to obtain enzymatic hydrolysate; step 4, heating the enzymatic hydrolysate, carrying out preliming, introducing nitrogen and carrying out settling separation so as to obtain first clear liquid; step 5, heating the first clear liquid, carrying out preliming, introducing ozone and carrying out settling separation so as to obtain second clear liquid; and step 6, heating the second clear liquid to a boiling state, removing impurities through filtering, carrying out cooling to room temperature and then successively carrying out ultrafiltration, evaporative concentration, crystallization and purging. Sugar prepared in the invention does not contain SO2, so the chromatic value and turbidity value of the prepared sugar are effectively reduced, and the purity and concentration of the prepared sugar are improved.

Description

technical field [0001] The invention relates to the technical field of refined sugar. More specifically, the present invention relates to a sugar cane sugar production process. Background technique [0002] More than 95% of my country's sugarcane sugar production is suitable for the sulfite clarification process, that is, using SO 2 As the main clarifying agent, with the Ca of milk of lime 2+ The reaction produces CaSO with strong adsorption capacity 3 Precipitation, the colloids, pigments and other non-sugar components in the sugarcane juice are adsorbed and precipitated together, and the SO 2 It also has the effect of good bleaching and inhibiting pigment production. However, due to the clarification process of sulfite method, the pH value is controlled in the neutral range, and sugarcane juice is a complex system, and the colloidal substances contained in it will hinder SO 2 with Ca 2+ Generate CaSO 3 Precipitation reaction, so unavoidable SO 2 Residues in clear j...
