Perry Belt Drier Logo

The Perry Belt Drier is ideally suited to drying almost any non-flowing product or more granular products that require a lower throughput capacity. Dependant on the exact nature of the product to be dried you can expect to reduce it by 20-30% of its original weight.* 

The Perry Belt Drier can significantly reduce the weight of almost any product that you currently send to landfill by reducing the moisture content within packaging and food waste and with it your costs.

Why Dry SRF?

  • Produce a high calorific fuel from waste which would have been sent to landfill
  • Burn dry SRF to produce heat & electricity
  • An increased demand in SRF sees a growing market

This happens in an automated process which passes the product along a drying belt.  These drying belts can be installed in your processing plants and give you a significant competitive edge by reducing your waste disposal costs.  That competitive edge could either improve your profit margin or help you reduce your prices so you win more bids.


The Perry Belt Drier can be adjoined to a variety of in house manufactured handling equipment to feed and discharge the driers, including: store conveyors, belt and bucket elevators, augers and screw conveyors, in addition to many more handling solutions.

General Design

Modular galvanised steel construction available in 1.5m, 2.2m and 3m widths. The drier can be increased in length in 1m increments from 8.5m to 38.5m (including drive and tail). The overal height of the drier is dependant on the heat source chosen.



Belt Drier Fuel Options

Heat Sources Available

These are commonly used for application where a biomass heat source is available such as woodchip boilers to produce hot water or if there is a steam heat source available.
The drier can be tailored to accept a customer’s existing heat exchangers if required.

If a separate heat source is required a direct fired furnace with diesel, kerosene, LPG or natural gas burner can be used. Alternatively a heat exchanger with the same burner can be used for indirect heating if required.

Belt Information

Polymer Woven Belt

  • An anti-static synthetic/bronze weave mesh which is well suited to low temperature driers. Temperatures of up to 130°C.
  • Best suited for smaller/finer products, or products which have a wide range of particle sizes such as woodchip.
  • The woven in bronze wires permanently prevent electro-static charging of the belt. 
  • The mesh has a high level of air permeability. 
  • Two Separate tracking rollers & two rotary cleaning brushes (one at the drive end & one at the tail end).

Perry Belt DrierOptions

  • Feeding hopper that can be used as a buffer hopper to help feed the product evenly over the belt. This feeding hopper will have a number of screw feeders dependent on the width of drier chosen. The hopper can be fed via dump loading, elevators, conveyors or screw conveyors.
  • Drier panels can be insulated along the drying section to improve heat retention.
  • A false floor option is available for a fully enclosed drier base. 
  • Perry Belt DrierA complete enclosure can be built around the drier to house the heat exchangers and the fans. This is built with insulated wall panels and two access doors (one in the hot & one in the cold plenum)
