Embodiment 1

[0036] A kind of preparation of compound enzyme clarifying agent for sugar industry:

[0037] By weight percentage, raw material formula is as follows:

[0038] α-glucanase 35%, pectinase 20%, amylase 35%, cellulase 10%.

[0039] The preparation method is as follows: the raw material enzymes are respectively filtered through a microfiltration membrane, then mixed in an automatic mixer in proportion, filtered through a fine filtration membrane, quantitatively filled, and become a product.

Embodiment 2

[0041] In terms of weight percentage, the raw material formula is as follows: α-glucanase 40%, pectinase 30%, amylase 10%, cellulase 5%, water 15%. The preparation method is the same as Example 1.

Embodiment 3

[0043] In terms of weight percentage, the raw material formula is as follows α-glucanase 60%, pectinase 23%, amylase 12%, cellulase 5%. The preparation method is the same as Example 1.

Abstract

The invention discloses a compound enzymatic clarifying agent for the sugar industry and a preparation method and application for the compound enzymatic clarifying agent. The compound enzymatic clarifying agent comprises, by weight, from 35% to 60% of alpha-glucanase, from 20% to 30% of pectinase, from 10% to 35% of amylases, from 5% to 10% of cellulase and from 0% to 15% of water. The preparation method includes proportionally mixing the alpha-glucanase, the pectinase, the amylases and the cellulase which are raw materials to obtain a mixture; and filtering the mixture via a fine filter membrane to obtain the compound enzymatic clarifying agent. The compound enzymatic clarifying agent is added during a working section for extracting juice from sugar crops, the feeding quantity of compound enzymatic clarifying agents added into 1kg of the sugar juice ranges from 10mg to 30mg, the sugar juice clarifying efficiency can be effectively improved, the viscosity of sugar liquor is reduced, the filtering speed and the settling speed are increased, the quality of sugar products is improved, the sugar yield is increased, an original sugar production process is unchanged, and operation is simple and feasible.

Description

technical field [0001] The invention belongs to the technical field of clarifiers used in the sugar industry, in particular, the invention relates to a compound enzyme clarifier. At the same time, the invention also relates to the application of the compound enzyme clarifier in strengthening the cleaning of sugar juice. Background technique [0002] When extracting sucrose from sugar crops such as sugarcane or sugar beet, the sugar solution is a typical colloidal solution containing various chemical components, the main components are: sucrose, reducing sugar, polysaccharide, protein, amino acid, organic salt, and various natural pigments, etc. . The composition and properties of the sugar solution are very complex, and the components are not stable. Various chemical changes often occur during the sugar production process, forming a highly viscous colloidal system, which makes the clarification and filtration of the sugar solution quite difficult. [0003] The formation of...
