Preparation method of lubricant for food machinery

Abstract

The invention provides a preparation method of a lubricant for food machinery. 70-85 parts by weight of poly(ethylene glycol) distearate and 12-15 parts by weight of monoalkyl polyethylene glycol ether are heated to 100-120 DEG C and stirred to be dissolved for 30-40 min, then 1-3 parts by weight of sodium dodecyl sulfate and 2-4 parts by weight of sodium erythorbate are added and stirred for 40-50 min, and the lubricant for food machinery is obtained. According to the method, harmful substances are not brought to food due to avoidance of use of aromatic compounds; equipment corrosion is reduced due to no use of chlorine-containing compounds; unsaturated compounds are not used, so that food pollution caused by oxidation is avoided; the product performance is excellent with adoption of the scheme.

Description

Technical field [0001] The invention belongs to the technical field of lubricant preparation, and specifically relates to a preparation method of a food machinery lubricant. Background technique [0002] The operation of food machinery must use specific lubricants that can fully guarantee food hygiene and safety. With the continuous improvement of the industrial mechanization of food processing, the consumption of food machinery lubricants is also increasing, such as crushers, mixers, pumps, can sealing machines, conveyors, bread ovens, gear boxes, hydraulic systems, etc. use. Lubricant contamination of food has always been a concern. Once lubricant-contaminated food enters the market, it may cause a series of food safety issues. In addition, the specific operating environment of the food production line, such as high temperature, low temperature, high humidity, etc., all put forward safety and use performance requirements for lubricants, including lubricants that need to have ...
