Problems solved by technology

The safety risk of the chemical composition of ordinary lubricants and the dangerous ingredients contained in them are real hidden dangers of lubricant pollution
In the food and beverage industry, the storage tank, filling valve and head of the liquid filling machine are the most prone to lubricant contamination. If ordinary lubricants are used or the lubricant is not selected properly, it will bring safety hazards to the product
Other common pollution sources include: dripping and splashing of lubricant (oil) in open lubrication, leakage of lubricant in hydraulic pipes, gearboxes, gear transmissions, oil-filled heat exchange systems, etc., compression caused by oil mist in oil-filled compression pumps air pollution

Abstract

The invention discloses a lubricant for food machinery and a preparation method thereof. The lubricant for food machinery comprises the following components in parts by mass: 50-80 parts of vegetable oil, 5-20 parts of sucrose, 1-8 parts of sodium chloride, 1-2 parts of amino acid, 2-6 parts of sodium aliphatate, 1-3 parts of sorbitol, 1-3 parts of citric acid, 3-8 parts of methyl aspartyl phenylpropionate and 0.5-2.5 parts of emulsifier. The amino acid is leucine or isoleucine. The emulsifier is oil-base amino acid sodium. All the components in the lubricant are food-grade materials which are safe and nontoxic, and the components are precisely proportioned to prepare the lubricant with excellent frictional property.

Description

technical field [0001] The invention belongs to the technical field of lubricants, and in particular relates to a lubricant for food machinery and a preparation method thereof. Background technique [0002] The food industry production line is composed of a series of food machinery and parts. The friction between mechanical parts will inevitably cause equipment wear and energy loss. Therefore, lubricants must be used for the operation of food machinery. Lubricant forms a lubricating film on the friction surfaces to reduce friction loss, heat dissipation, rust removal, vibration reduction and noise reduction. At present, the degree of mechanization of the food industry is getting higher and higher, and lubricants have been widely used in various food machinery, such as crushers, mixers, pumps, can sealing machines, conveyors, bread ovens, gearboxes, hydraulic systems, etc. Contamination of food by lubricants has always been a concern. In the process of food production, hos...
