Abstract

The invention provides a food-grade vacuum pump oil composition mainly composed of synthetic oil, which includes the following components in weight percentage: 0.1-4.0% of food-grade high-temperature antioxidant, 0.2-4.0% of food-grade high-temperature detergent and dispersant %, food grade extreme pressure antiwear agent 0.05~4.0%, food grade anticorrosion inhibitor 0.01~2.0%, food grade rust inhibitor 0.01~5%, food grade antifoaming agent 0.01~2%, food grade base oil 30~ 95%, the balance of ester oil; the ester oil is a mixture of one or more of saturated polyol esters and complex esters. The food-grade ester oil is preferably polyol ester or complex ester with suitable viscosity. The food-grade high-temperature chain oil composition of the present invention meets the approval requirements of the National Sanitation Foundation H1, and has the advantages of excellent extreme pressure and anti-wear properties, oxidation stability, and corrosion resistance. In addition, it has a lower limit Pressure, lower pour point and higher viscosity index, can be used in vacuum pump equipment in food processing and other fields.

Description

technical field [0001] The invention relates to a food grade vacuum pump oil composition, in particular to a food grade synthetic oil type vacuum pump oil composition. Background technique [0002] Food processing equipment is mainly used in food processing such as meat products, dairy products, etc., in addition to food packaging, pharmaceuticals, tobacco, animal feed, and daily chemical products and other industries. Various components of food processing equipment, such as hydraulic systems, bearings, gears, chains, compressors, vacuum pumps, etc., require the use of special lubricants. In addition to ensuring the effective lubrication of the equipment, such lubricants must meet more stringent standards. Ensure that food safety can still be guaranteed in case of occasional contact with food, etc. [0003] The National Sanitation Foundation (NSF) is currently recognized as an authoritative organization in the field of food industry safety worldwide. It continues the work o...
