In mechanical equipment, grease is required for every running part, and so is food machinery. However, due to the particularity of the food industry demand, in the process of food production and operation, some grease and inadvertently come into contact with food, you need to use food grade grease, food-grade grease NSFH1 certification and FDA standards to meet the specified requirements, can to the lubrication of mechanical equipment at the same time reduce the pollution to food.
Food grade greases are mainly prepared from base oils and additives. Because food-grade grease is mainly used in the food industry, the requirements for lubricating oil are very strict, not only to meet the lubrication requirements of machinery, but also do not pollute products and affect food safety. The lubricant should have very good oxidation resistance, high and low temperature resistance and demulsification performance. For food processing machinery that is easy to breed bacteria and microbial reproduction, lubricants should also have good anti-microbial reproduction characteristics.
Selection of food grade grease:
1) Replace the same type of grease or grease with similar performance as far as possible;
Different kinds of food-grade greases, due to their different base oil and additives, mixing may react, so that the additives fail, precipitation, flocculation and other situations are more likely to occur, seriously affecting the performance of the grease.
2) The viscosity should be equal
The viscosity of substitute grease should not exceed ±15% of crude oil. Grease with slightly greater viscosity should be preferred;
3) High quality instead of low;
At present, the mainstream grease optimization initially used mineral food grade grease, but now the use of synthetic food grade grease, can greatly improve the service life of grease, prolong the cycle of grease replacement, and improve the lubrication effect.
4) The environment and working temperature of mechanical equipment should also be considered
No matter when, food grade grease needs to pay attention to the working condition of mechanical equipment. The newly selected food-grade grease also needs to meet the working conditions of mechanical equipment to avoid lubrication failure.
Application of food grade grease:
Used for lubrication of bearings, gears, chains, bushings, slideways, valves, etc. of food filling, sealing, packaging and washing equipment in wet environment or in wet environment.
Used for the lubrication of pharmaceutical, cosmetic production equipment, cleaning equipment, filling equipment, packaging equipment, steam equipment.
Used for noise reduction, lubrication and sealing of bearings, gears and guide rails of canning machine, canning machine, conveyor, juicer, grinder, blender, bread machine, etc.
