Abstract: A method for sanitizing biomass in which the biomass is fed to a shaft cooler, and the biomass is heated in the shaft cooler by supplying a heated heating medium to the shaft cooler.

Abstract: A process and plant for drying of wood shavings, wood chips or other solid materials of organic and/or mineral origin in small pieces, in which—the material is predried by means of a first preheated drying gas in a first drying step,—the dried material from the first drying step is dried by means of a second preheated drying gas in a second drying step,—ambient air is heated and supplied as second preheated drying gas to the second drying step,—the dried material from the second drying step is cooled by means of a cooling gas, and—the cooling gas heated by cooling of the material and/or the second drying gas cooled in the second drying step is supplied as first drying gas to the first drying step.

Abstract: A pellet cooling device featuring energy-efficient heat recovery in a plant for producing wood pellets or other solid granulates from small pieces of organic material, said plant comprising devices for feeding, processing, drying, compressing, cooling and discharging the material. At least some of said devices are arranged in containers that can be individually transported and can be modularly combined to form at least a substantial portion of the plant.
