Producing food is a demanding science. All industrial products and equipment used to make food must meet stringent quality and hygiene requirements. In industrial bearings, the food industry must consider unique options. For example, do you want lubricants to contaminate food on the production line? Or what if the bacteria grow in the outer casing of the machine? Consumers can at least postpone speaking.
Although industrial bearings must be carefully selected for cleanliness and hygiene, they must also be evaluated for strength, hardness, durability and cost. It requires a special set of materials to meet all of these standards.
Choose industrial bearings and plug-ins
The ball and ring itself must be made of high performance materials; ordinary iron does not meet FDA and USDA standards. A common choice in the industry is to use stainless steel balls and rings. They have high tensile strength and good corrosion resistance and do not contaminate food. However, they are one of the most expensive options, so other materials are also designed as balls.
The plastic mixture can be used alone or in combination with stainless steel, especially in plain or non-rolled industrial bearings. Coated iron is also a cheaper option. A chrome coating will improve the shape of the ball. Hardness and corrosion resistance increase its durability. Zinc coatings are also commonly used to improve corrosion resistance and prevent contamination.
Housing materials
Industrial products, such as machine casings, are also subject to strict standards because they come into contact with food during the production process. Typically, the outer shell must be a smooth surface to facilitate cleaning and help prevent the accumulation of bacteria and bacteria that may occur in rough or porous materials. Polished casings are very common, and antimicrobial coatings help protect industrial products and casings.
When considering structural materials, the outer casing is usually also stainless steel. A combination of strength, durability and corrosion resistance is required. Industrial products in the food industry will be subject to acidic and corrosive rinsing and cleaning, as well as oils and other organic materials from the ingredients themselves.
Again, the available options are cheaper. The plastic and polymer blends are also chemically inert and resistant to cleaning solutions and foods. Plastics with high tensile strength and a smooth surface can be produced. Coated iron is also suitable for the outer casing. Nickel or Teflon coatings will greatly help prevent corrosion and contamination.
Industrial bearings and lubrication
The use of traditional oils and lubricants is clearly hidden in the food processing industry. Lubricant contamination can damage food, produce a terrible taste, and be toxic if consumed. Always use FDA and USDA approved greases for the food industry. These lubricants are called "H1' and have no odor and taste. They are non-toxic if they are contaminated with processed foods. H1 is also carefully formulated to withstand common food-grade chemical cleaning and for cleaning industrial supplies. Program.
Always maintain good lubrication of industrial bearings; this rule has not changed for the food industry. Cleaning and refilling the oil tank also helps prevent cross-contamination. If a particular machine is difficult to repair, a solid polymer lubricant can be used. These solid strips slowly release grease during industrial bearing operation to keep the system lubricated. This way, when there is more time to maintain a particular machine, the lubricant can be refilled during shutdown and turnaround.
Finish assembly and other supplies
There are also some applications in food processing that require special seals. When high or low temperatures are used, such as during cooking or freezing, the silicone material will remain tightly sealed during these temperature changes.
Stainless steel is still common for other components of the assembly. In particular, the cage is usually stainless steel or nylon to save money. Fixing screws and grease fittings should also be stainless steel. Flingers can be stainless steel or iron, and all collars should also be corrosion resistant.
Industrial bearings with graphite spacers are also ideal for high or low temperature applications. At temperatures at which other greases fail, the graphite material will act as an additional lubricant. This type will extend service life while reducing maintenance costs in extreme temperature applications.
In general, choosing the right industrial bearings and other supplies for the food industry requires only a little extra effort, but it still has a long way to go to ensure a clean meal for consumers.
