Problems solved by technology

[0007] Usually, the filter and slag removal is carried out by using a pre-coating filter. The pre-coating filter aids are filter soils such as diatomite and perlite. Since the sugar residue in glucose production is some bonded protein flocs, after pre-coating and filtering and After drying, a lot of inorganic filter soil may be bonded and contained in the protein flocculation particles, and it is difficult to separate them even through a high-efficiency cyclone separator. The feed processed with sugar slag mixed with inorganic filter soil will greatly affect its quality. Commodity value and nutritional value of processed feed products

Abstract

The invention discloses a sugar liquid filtering method of lignin, which is characterized by the following: adopting lignin to replace filter soil as filter aid and sugar residual precoating; reaching low-adhesivity for sugar residual protein; filtering conveniently; avoiding utility value reduced by residual lignin.

Description

Technical field: [0001] The invention belongs to the field of comprehensive utilization of corn deep processing, and relates to a glucose production method, in particular to a slag removal and filtration method in glucose production. Background technique: [0002] my country is a large agricultural country with rich resources of agricultural products. The total output and commodity volume of major agricultural products rank among the top in the world. Therefore, deep processing of agricultural products is a promising industry. [0003] Corn is one of the most important food crops grown by humans, accounting for about a quarter of the world's total food crop production. Corn is also the main food crop variety in my country, and its total output is second only to rice and wheat, ranking second in the world. Its comprehensive processing is an economic field waiting to be developed urgently. [0004] Corn has the advantages of fast maturity, high yield, wide planting area, hig...
