Food Processing Conveyors

Reliable, Hygienic & Easy to Clean Food Grade Conveyor Belt Systems 

Food processing conveyor belts face must withstand a variety of unique and extreme stresses, from high-heat baking and drying conveyor systems to steam applications to cooling and freezing conveyor belts. Food grade conveyor belt systems must handle these and other stresses repeatedly and often continuously, without sacrificing efficiency or product quality.

Stainless steel and carbon steel food grade conveyor belt systems from Berndorf Belt Technology USA, designed in partnership with our partner companies and are specially engineered to resist production stresses and provide unparalleled conveyor belt flatness and straightness.

Benefits of Berndorf Food Grade Conveyor Belt Systems

Belts are manufactured in “endless” condition between two drums. This ensures belt straightness and flatness, as well as precise tracking, and results in less downtime and longer belt life.

For baking applications, belts feature a dark, uniform heat-absorbent surface area. This improves product quality and increases energy efficiency.

Belts are designed and manufactured for superior flatness, which results in improved product quality and reduced scrap/waste.

Installation and maintenance by certified Berndorf Service Technicians are available to guarantee top quality workmanship, reduce your downtime, and increase your profitability.

Special Features of Berndorf Food Processing Conveyor Belts

Berndorf’s freezing conveyor belts, cooling conveyor belts, baking and drying conveyor belts, and other food grade conveyor belt systems are designed with special attention to key components, such as tension terminals and belt tracking devices. This makes our machines especially well-suited to the severe working conditions they encounter, including temperatures from -76° to 212°F (-60° to 100°C) and constant, 24/7 production.

Steel Belt Freezing Conveyor

Our freezing conveyor belts feature advanced cooling systems to provide fast and efficient product cooling. The steel belt itself provides the platform on which products are frozen, while the specially engineered freezing plant produces the low temperatures required. Our continuous steel belt freezing conveyor systems are used in the production of coffee, diced/dried fruit, candy bars, chewing gum, sauces, meats, cheeses, and many other products.

We offer two freezing systems, air, and fluid. In our air freezer systems, the steel belt machine is installed inside a tunnel enclosure, where loop circulation of -22° to -58°F (-30° to -50°C) air blasts the product to freezing temperatures while it is conveyed along the moving steel belt.

In our fluid-cooled freezing conveyor systems, the inferior side (bottom track) of the belt is sprayed with a low-temperature (14° to -4°F; -10° to -20°C) thermal solution. This lowers the belt’s temperature enough that product freezes on contact.

Cooling Conveyor Belts for Chocolate

When used in chocolate production, Berndorf’s food grade conveyor belt systems are typically contained in a special tunnel enclosure that maintains the ideal temperature for cooling chocolates into their solid form.

Product is distributed onto the steel belt surface at one end of the conveyor (feed end) and travels the length of the conveyor. As it travels along the conveyor, the product cools, and as it becomes fully cooled, it falls onto a separate transfer conveyor located below. Product scrapers ensure proper product transfer between belts. Belt speed is adjustable to accommodate the ideal retention time needed for the product to fully cool on the chilled steel belt.

Double Belt Cooling Conveyor Belts for Gum Base

Our double belt cooling conveyors are essentially comprised of one food grade cooling conveyor system, flipped upside-down and stacked on another, normally-aligned cooling conveyor. While the bottom belt holds the product’s film in place to be cooled down, the top belt lays on the product’s film and cools its top face.

Double cooling conveyor belts are especially useful in applications where:

  • the product tends to curl or rise during the cooling process, thus losing contact with the cooling surface
  • the product is a poor heat conductor and/or must be fed through at high thickness
  • the available floor space is not sufficient to install a longer, single-belt system

Single Cooling Conveyor Belts for Nougat

These Berndorf single belt cooling conveyors can be used for a wide range of food products. The system’s feeder is selected in respect to the characteristics of the product being processed in order to achieve the proper thickness and consistent distribution across the conveyor belts full width. Downstream, a variety of equipment can be installed to break, cut, pile, and/or wrap the product.

Our cooling conveyor belts are manufactured using only food grade components and raw materials.

Specialty Conveyor Belts for Meat Handling & Pet Food Processing

Because of the extremely high levels of cleanliness required, stainless steel conveyor belts are essential for meat handling and pet food processing. Frequent cleaning and sterilization are required to remove the bacteria, blood, and other potential pathogens encountered in these applications. Studies have shown that stainless steel conveyor belts are easier to clean, and get cleaner overall, than plastic or other belt materials; this is especially true of belts that exhibit wear and tear from daily operations.

Berndorf uses food grade components and materials to help you meet industry standards for cleanliness and to make cleaning and sterilization fast and easy. Our stainless conveyor systems are durable and dependable. The belts won’t be damaged by cutting operations, and the entire system is designed to stand up to repeated deep cleaning and the day-to-day rigors of meat and pet food processing applications.
