The triple-pass dryer for wood chips and biomass by Uzelac Industries has a number of unique advantages over similar dryers. Its bolt-on tire design reduces maintenance and increases tire life, while the overhead drive reduces wear on the rollers. Access doors on the outer and intermediate cylinders allow for easy inspection and cleaning of all three cylinders of the drum. Uzelac Industries also custom-designs and manufactures its own equipment, offers project management and 3D modeling, and supports hundreds of dryer installations in North America with parts and service.

Thompson Dryers
Thompson Dryers believes products should work like they are supposed to. Armed with this belief and more than 70 years of experience, Thompson designs industrial rotary dryer systems for the biomass, forest, ethanol, livestock feed, and fertilizer industries – primarily in North America and Europe. Proprietary technology ensures products are dried uniformly with minimal air pollution, little material degradation, and low fire risk. Thompson also offers a wide range of solutions to handle all dryer repair and maintenance needs including alignment and resurfacing, inspections, parts, drive, bearings, trunnions, drum crack repair and more.

Stela Laxhuber GmbH specializes in low temperature belt drying technology. Continuous developments and customizable optimization in various applications allows Stela to be called a technology leader in this expanding market. One of the greatest benefits using high efficiency belt dryers reflects by usage of waste heat or other low-temperature sources. The latest development of the Stela RecuDry system with heat recovery scores an energy savings of around 35-55 per cent compared to common standard drying systems.

The Wyssmont Turbo Dryer Thermal Processor has long been used in vapour recovery systems, heat recovery systems, and environmentally sealed systems specially designed with condensers for products such as biomass and biofuels. The processor recently produced one million pounds of torrefied wood for a test burn in a mixed coal power plant. It operates at 300°C to produce wood with a heating value equivalent to coal.  The Wyssmont Turbo Dryer Thermal Processor can be the best solution for your drying needs.

Dieffenbacher high-capacity drum dryers are well recognized for their efficiency and reliability. They are the ideal solution for drying wood particles for particleboard and pellet production, strands for OSB production, disintegrated seasonal annual crops and other biomass. The dryer internals are designed according to the material characteristics for high thermal efficiency and low moisture fluctuation. Dieffenbacher drum dryers meet high safety standards. The perfect integration of energy systems and drum dryers creates additional value for customers, from the planning phase through the complete lifecycle.

GEA has become the preferred supplier of drying technology in the bio-ethanol industry, providing distinguished product quality. To increase efficient energy usage, systems can be heated by turbine exhaust gases or utilize exhaust gas-recycle which also renders the system inherently safe. The Feed-Type Ring Dryer is designed for drying feed and fibrous materials where extended drying times are required without product damage. Features include a cold disintegrator for breaking up agglomerates and a manifold for recycling heavier and wetter particles back to the disintegrator. GEA also has experience drying other moist materials including corn fibre/gluten, wheat and corn feed, cellulose and lignin. This dryer is capable of evaporative capabilities of up to 30 tonnes per hour.  GEA will pair the Ring Dryer with a Fluid Bed Cooler for final powder conditioning.

Earth Care Products
ECP’s Z8 Rotary Dryer is a patented reverse flow, impinging-stream dryer design with increasing thermal-velocities providing maximum heat-transfer with multi-stage dehydration within drum embodiment. The material first passes through a single-pass section and then through a reverse-flow triple-pass section, and then repeats the process. This provides uniform dehydration of all particle sizes with no overheating of fines with increased production capacity and minimized VOC emissions. The Z8 Rotary Dryer can be designed as a drop-in replacement for Single-Pass and Conventional Triple-Pass Rotary Dryers.  ECP’s technology includes trunnion bases, saddle drives and high efficiency cyclone collectors.
