What Are Food Grade Conveyor Belts Made Of

As an important carrying tool in food production and processing, food conveyor belts are of relatively important significance to food safety in food production. Different processes, environments, and design requirements in food production also have different requirements for food conveyor belts. So, what are food-grade conveyor belts generally made of? Generally speaking, food-grade conveyor belts include PU conveyor belts, PVC belts, Teflon belts, silicone belts, etc. The following section introduces how these light conveyor belts used in food grades are made and describes their characteristics.

Food grade conveyor belt

The material used in a relatively large proportion of food conveyor belts is PU material. The characteristics of polyurethane are excellent wear resistance, excellent ozone resistance, high hardness, high strength, good elasticity, low-temperature resistance, good oil resistance, chemical resistance and environmental resistance. Such material characteristics make PU conveyor belts oil-resistant, corrosion-resistant, cold-resistant, and cut-resistant. It is a conveyor belt product with high strength, good flexibility, lightness, and wear resistance.

Compared with PU conveyor belts, PE conveyor belts, which are widely used in the tobacco industry, are made of polyethene polymer materials. Polyethene is tasteless, odourless, and non-toxic. PE conveyor belts have high tensile strength and good bending properties. They are thin, oil-resistant, non-toxic, and easy to clean. PE conveyor belts meet the FDA food hygiene standards of the United States. They have good wear resistance and physical aging resistance and are durable conveyor belt products.

In food processing, we will encounter some high-temperature resistant sections, and the conveyor belts need to have a certain high-temperature resistance. Then silicone belts and Teflon products have become one of the choices in these sections.

Silicone belts are made of high-temperature resistant materials, such as silicone and polyester cloth. Organic silicone has high thermal stability, and the chemical bonds of the molecules do not break or decompose at high temperatures. Organic silicone is not only resistant to high temperatures but also resistant to low temperatures and can be used in a wide temperature range. Due to the physical and chemical properties of silicone, silicone conveyor belts have good heat and cold resistance and good weather resistance. It is one of the special application options in the food industry.

Teflon conveyor belt is a product used in many baking and packaging sections. It is also called polytetrafluoroethylene conveyor belt, Teflon conveyor belt, etc. Polytetrafluoroethylene is called the “king of plastics.” The raw material can be used for a long time at -180-260℃. The surface friction coefficient is extremely low, so Teflon conveyor belt is also an anti-stick material.

In food transportation, light conveyor belts are commonly used, and PVC conveyor belts and PU conveyor belts are the more common types. Although they are both industrial conveyor belts, the difference lies in the different ingredients: the rubber surface material of PVC conveyor belt is polyvinyl chloride, which has a relatively low food grade and is relatively less used, while the raw material of PU conveyor belt is polyurethane, which meets food hygiene standards, can be in direct contact with food, has a moderate colour and no odor.

Conveyor belts that can be used in the food industry usually meet food safety standards (such as relevant certifications from the FDA and EU). SCplus Conveyor Belt has focused on the food industry for more than 15 years. Our food conveyor belts are food safe, easy to clean and disinfect, and are a trustworthy food conveyor belt supplier.
