SWISS COMBI - Waste Heat Utilization Belt Dryer
The SWISS COMBI Belt Dryer stands out as a solution tailored for efficient drying using waste heat, harnessing this energy in a sustainable manner by employing hot water, condensate, or steam to heat air up to 110°C. This process effectively lowers the moisture content in organic materials to as low as 2%, supporting industries such as particle board and pellet production, alongside applications in the sugar, feed, and biomass combustion sectors. Available in single or double-layer configurations based on moisture reduction targets, the belt dryer features a modular design and compact form for flexible installation. Its engineering emphasizes low emissions, minimized power usage, and cost-effective maintenance. With a portfolio of over 200 installations, SWISS COMBI offers custom drying solutions for varying material properties, addressing challenging requirements with bespoke systems worldwide.

The SWISS COMBI belt dryer utilizes waste heat, making it an excellent fit for the current era of intelligent energy utilization. With over 200 installations worldwide, this drying technology satisfies our customers daily.
Our belt dryer, also known as a Low-Temperature Dryer (LTD), gently dries your product using hot air. Waste heat in the form of hot water, condensate, or saturated steam serves as the heat source, heating the ambient air up to 110°C. Depending on the product requirements, the drying process reduces the moisture content of the product to a range of 40% to 2%.
The SWISS COMBI belt dryer is suitable for organic bulk materials that are permeable to air and have low odor. It features a modular design, low emission values, low power
consumption, and low maintenance costs.
Depending on the desired moisture content of the dried product, a single-layer or a double-layer belt dryer is employed. For products with a required moisture content higher than 20% after drying, a single-layer belt dryer is suitable. If the residual moisture needs to be below 20%, a double-layer dryer is ideal.
Depending on the available space, multiple units can be built above or beside each other.
Pellet industry
Sawdust from the production of wooden boards or other sources is processed into wood pellets.
Sugar industry: Sugar beets
Sugar beet pulp is pre-dried or end-dried on the belt dryer after leaching and processed into a feed.
Sugar industry: Bagasse
After extracting the sugar juice from the sugar cane, bagasse remains, which can be used in the sugar factory as fuel to produce steam and electricity.
Feed industry
Belt dryers are used for drying grass or alfalfa (lucerne) into feed when product quality is very important.
Combustibles
Drying of wet biomass for subsequent combustion in a power plant or boiler, or as preparation for a pyrolysis process.
