Problems solved by technology

The current beer bottle cleaning agent is mainly composed of alkali, surfactant and other components. The system has poor anti-dirt redeposition ability and mainly has the following disadvantages:
[0003] 1. After the dirt is peeled off, due to the fast sedimentation speed, it attaches to the beer bottle for the second time, which not only affects the cleaning ability of the dirt, but also easily makes the equipment scale
[0004] 2. The performance of the cleaning agent is single, it can only descale and clean, but cannot eliminate the adverse effects of bacteria and molds that grow inside the beer bottle on the hygiene of the beer bottle, and the cleaned beer bottle is poor in hygiene

Abstract

The invention discloses a preparation method of a beer bottle sterilizing detergent based on a microcrystalline cellulose / silver composite material. A nanocrystalline cellulose suspension prepared byan enzymatic method is mixed with silver nitrate and then a hydrothermal synthesis reaction is carried out to obtain a nano-silver loaded nano microcrystalline cellulose suspension, a biological surfactant, alkali and other raw materials are added and uniform mixing is carried out to obtain the beer bottle sterilizing detergent. The beer bottle sterilizing detergent prepared by the preparation method not only has the advantages of strong detergency, good anti-dirt redeposition ability, easiness for rinsing and removing dirt, and good cleaning effect on beer bottles, and can reduce scaling of equipment and is favorable for smooth running of a whole system, but also synchronously achieves sterilization and disinfection of the beer bottles with good bactericidal effect, and effectively improves the hygiene performance of the cleaned beer bottles.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a method for preparing a beer bottle sterilizing cleaning agent based on microcrystalline cellulose / silver composite material. Background technique [0002] As the output of beer continues to rise, in order to save production costs, many companies have begun to use recycled beer bottles. In order not to affect the internal quality of beer products, the cleaning of beer bottles is a key process for recycling beer bottles. The dirt composition of beer bottles is quite complex, mainly including: dust, grease, protein, wine scale, gum, mold spots, adhesives and so on. The current beer bottle cleaning agent is mainly composed of alkali, surfactant and other components. The system has poor anti-dirt redeposition ability and mainly has the following disadvantages: [0003] 1. After the dirt is stripped off, due to the rapid settling speed, it adheres to the beer bottle body fo...
