Industrial scale food processing can take place on continuous moving food drying belts. These are large scale ovens that are designed to efficiently remove moisture from various food stuffs they often utilise a PTFE mesh belt to convey the product through the process.
We make PTFE mesh food oven drying belts in apertures ranging from 1mm square up to 6mm square depending on the size of product being conveyed.
Smaller cereal products would tend to use 1mm or 2mm square belts where as some larger animal treat products would benefit from a larger mesh providing ample support as well as sufficient airflow to dry the product.
PTFE mesh conveyor belts usually have 25mm wide edge reinforcements or hems that bind and protect the edges and prevent the mesh from fraying.
PTFE films are most common and cost effective and in a large number of applications provide ample protection. Some ovens have automatic tracking systems that have pedals that tell the tracking roller to alter when the edge of the food dryer belt comes in to contact with it.
PTFE films are too thin and unstable for this so Techbelt applied more arduous PTFE glass cloth types of it specialist CF series.
A number of joints can be offered to be made to food drying belts however as airflow is something that is often crucial a joint that can also allow air to pass is preferred. Techbelt offers two main styles of joint that do this being the peek or Inox spiral type of Kevlar loop type used in food drying belts.
