Problems solved by technology

At present, membrane separation technology has been successfully applied in the fruit juice industry, and the application research in the sugar production of sugarcane sugar factories has also been reported, but the existing membrane technology in the sugar industry has not got rid of the traditional production aids (phosphoric acid, lime milk, sulfur , polyacrylamide and other chemical agents), and the final product is still limited to white sugar, the membrane separation performance has not been fully utilized, and some membrane processes need to add additional auxiliary agents such as amylase. The current industrial application of membrane technology in sugar factories still difficult to achieve

Embodiment 1

[0025] Example 1 Using "ultrafiltration-reverse osmosis" to prepare nutritional sugar, flavor cane juice and feed materials in parallel

[0026] The first step is the pretreatment of raw material juice and the separation of feed raw materials

[0027] Pump the sugarcane squeezed juice or the initial sugar factory juice into the filter press, and use a filter cloth with a pore size of 74 μm (200 mesh) as the filter carrier to remove large particles of impurities such as cane chips and cane pith in the raw juice The retentate sent back from the primary membrane separation process (ultrafiltration) is filtered again, and the filter residue is regularly discharged for feed production, and the filtered juice is used for ultrafiltration treatment. The operating temperature is 25°C, and the raw material barrel and filter press are sterilized with steam after filtration.

Abstract

The invention relates to a method for parallel production of nutrient sugar, flavor cane juice and a feedstuff by multistage membranes. The method comprises: conducting pretreatment to raw juice for removing bagacillo, bagasse pith and other large granular impurities so as to obtain a filter residue or scum, which can be used as a feedstuff, pumping the obtained cane juice into a first stage membrane separation system so as to obtain clear cane juice, which is then subjected to a second membrane separation system for dehydration and concentration, using a permeated liquid for producing flavor cane juice or low-sugar beverages, and carrying out evaporation and spray drying treatment to a concentrated cane juice so as to obtain nutrient sugar. Based on the integration of membrane process separation, concentration, cold sterilization and other functions, the method of the invention carries out parallel production of nutrient sugar, flavor cane juice and a feedstuff, and has the advantages of no need for adding chemical agents, low production energy consumption, realization of maximum preservation of natural nutrition and flavor of finished sugar, simple and stable operation, basically no discharge of ''three wastes'', and broad adaptability, thus being in favor of optimization and upgrading of sugar products as well as comprehensive utilization of sugar resources.

Description

technical field [0001] The invention relates to a method for cleaning and concentrating cane juice by using multi-stage membrane separation technology, and producing nutritional sugar, flavor cane juice and feed raw materials in parallel. Background technique [0002] Sugarcane squeezed juice is used as the raw material for sugar production, and its main components are water, sucrose, organic non-sugars (proteins, polysaccharides, reducing sugars, phenols, etc.) Although organic non-sugar has high nutritional value, it will affect the production and quality of white granulated sugar. Therefore, removing "impurities" with nutritional value in cane juice is an important part of the traditional sugar making process. Cane sugar factories in my country mostly use phosphoric acid-sulfurous acid process to produce farmland white granulated sugar. The production process needs to consume a lot of chemicals (lime milk, phosphoric acid, sulfur, polyacrylamide, etc.) to absorb and remov...
