Precision Indexing with Stainless Steel Conveyor Belts in Freezing Operating Environments

sample testing equipment

Belt Technologies has years of experience designing and producing custom conveyor systems for automated pharmaceutical equipment and medical manufacturing applications. Recently, a client approached us with a challenge. Their goal was to improve upon and modernize the design of a machine they have been producing for nearly a decade. 

Achieve Maximum Accuracy and Efficiency for Medical Applications

The equipment being updated was designed to sample vials as they are conveyed through the system for testing. In the original design, the vials were held in a tray system as they are moved through the machine. A needle is then lowered into each vial to take a sample for testing. The equipment was intended to allow producers of food, pharmaceuticals, chemical compounds, and more, to take samples of the materials being produced and perform quality testing directly on the production floor— instead of sending product samples to outside service providers for testing.

The customer wanted to increase the efficiency of the system and double product yield in a single batch. To do this, they needed to improve the positional accuracy of the vials as they were conveyed through the system. They recognized that a metal belt would be the best belt material option as the ambient temperature of the operating environment is kept below freezing.

Belt Technologies has provided metal belts for a variety of applications in freezing temperatures, including cryogenic processes. Stainless steel has a high resistance to extreme temperatures, and can easily handle refrigerated operating environments. Metal belts are also highly accurate and repeatable, providing precise positioning of the vials with virtually no slippage.

Additionally, solid metal conveyor belts do not outgas or require lubrication, so there is no risk of contamination to the sensitive products being conveyed. They also will not fray or generate particulates that could contaminate medical products and potentially skew testing results. The flat, nonporous surface of stainless steel does not absorb bacteria and is easy to clean with virtually any cleaning method required, making it the ideal choice for this application. 

Custom Solutions Guarantee Optimal Processing Results

After working with the client to finalize their design, Belt Technologies provided the customer with a seamless belt made of 301 full hardened steel. It features custom vial holder attachments that are firmly attached to the metal belt.  We also added a custom perforation pattern in the belt for tracking and precision indexing. With the metal belt, secure attachments and timing features, the new equipment will be able to sample vials at a faster rate of speed without risking product quality or testing accuracy.

Stainless Steel Heat Sealing Bands for Sustainable Paper Packaging in Food Processing Application

Belt Technologies is experienced with the unique needs and requirements of a variety of specialty packaging applications. One of our longstanding customers is an OEM specializing in the manufacture of heat sealers for the food processing industry. 

Stainless Steel is Ideal for High Heat Applications

For this specialty packaging application the heat sealer would be applied to a paper bag that is filled with the food product by a hopper, then moves through the heat sealing bands to close it. In previous models, Teflon sealing bands were used to seal plastic packaging materials. Plastic based packaging can be heated at low temperatures, however, it is not a sustainable material option. The newer product bags were made of paper which uses a stronger adhesive, necessitating the use of higher temperatures to properly seal the bags.

While a Teflon band would typically be the more cost-effective option, the seams of the Teflon bands would fall apart at the required 500°F. Stainless steel has the advantage of high thermal conductivity, allowing for a higher rate of heat transfer and even sealing. Our engineers advised the client on the specific grade of stainless steel that would be the most effective and supplied them with a seamless metal belt for their heat sealing equipment. 

Heat sealing bands by Belt Technologies are smooth, durable and accurate, making them the ideal choice to reliably handle the rate of production in a variety of specialty packaging applications. They are capable of sealing any thermoplastic material and apply heat evenly and efficiently.

Automated Food Processing With Stainless Steel Conveyor Belts



Stainless steel conveyor belt systems are ideal for the cooking, freezing, and handling of edible products. They are versatile and can easily be customized for any automated food processing system with exceptional results.

Metal conveyor belts do not outgas and do not require lubrication, which means there is no risk to the flavor or quality of the foods being processed. Unlike other conveyor materials, like wire mesh, fabric, or rubber, metal belts will not deteriorate or generate particulates that could contaminate food products.

Endless metal belts have a flat, nonporous surface and will not absorb bacteria. Conveyor systems from Belt Technologies are easy to sanitize between uses. They are resistant to chemical corrosion and can be sanitized with almost any standard cleaning method.

Metal belts can easily transition between hot and cold applications. They last longer and are more reliable than plastic conveyor belts in extreme temperatures. Stainless steel belts are excellent for cooking and handling raw materials because of their high thermal conductivity. Food is cooked thoroughly and evenly thanks to the quick, even transference of heat.
