 This biomass drying equipment, now available on the market, enables the continuous dewatering of various agricultural and forestry biomass feedstocks—such as sawdust, wood chips, rice husks, straw, fruit pomace, and palm shells. It effectively addresses key industry challenges, including the tendency of high-moisture biomass to mold, its low calorific value, and the difficulties associated with its storage, transport, and further processing.

The equipment operates on the core principle of rotary hot-air heat exchange. The integrated system comprises a feeding mechanism, a heat source, an inclined rotary drying drum, internal lifting flights, an induced-draft dust collection system, and a discharge unit. High-moisture biomass is fed uniformly into the drying drum, which rotates continuously at a low speed. Inside, specialized lifting flights repeatedly scoop up and disperse the material, creating a uniform "curtain" that ensures thorough contact with the clean, heated air—facilitating stable convective heat exchange. The drying process occurs in two stages: the evaporation of surface (free) moisture, followed by the migration and release of internal moisture. The hot air continuously carries away the moisture released from the material. Driven by the negative pressure from an induced-draft fan, the moisture-laden exhaust gas is directed into a dust collection system for purification, ensuring emissions meet environmental standards and preventing dust leakage. Operators can adjust the hot-air temperature, drum rotation speed, and feed rate based on the specific characteristics of the raw material, allowing for precise control over the final moisture content to meet the requirements of downstream processes such as carbonization, briquetting, or pelletizing.

Raw biomass typically exhibits significant moisture fluctuations; when piled up, it is highly prone to decay and spoilage, and its direct combustion yields a low calorific value. Processing the material through this dryer allows for controlled moisture reduction, significantly increasing its calorific value and stabilizing its volume, which substantially lowers storage and transportation costs. The equipment is highly versatile, capable of handling a wide range of loose biomass materials—including wood and bamboo chips, peanut shells, sugarcane bagasse, and distillers' grains. It supports stable, 24-hour continuous operation, offering high thermal efficiency and superior energy consumption control. The industry for the resource utilization of biomass is currently developing rapidly, with a sustained rise in demand for the recovery and processing of solid waste from agriculture and forestry. As a core piece of equipment for front-end pre-processing, biomass dryers serve as a critical link in transforming waste into renewable raw materials; consequently, they hold significant market potential—both domestically and internationally—within the sectors of energy conservation, environmental protection, and the circular utilization of solid waste.
