A belt conveyor transfers wet biomass from a ground-level hopper to the rotary screen. Equipped with a magnetic separator, this conveyor effectively isolates magnetic material such as iron pieces from the biomass.

To ensure optimal drying results and prevent blockages in the system, it's crucial to pre-screen wet biomass before introducing it to dryer equipment. In our process, we utilize a rotary screen with an opening diameter of 8mm and a hexagonal shape that promotes tumbling motion during operation - facilitating separation of oversized particles.

Augers are thoughtfully placed in the screen to facilitate the smooth movement of biomass across it. This measure affords enough residence time for complete separation of oversized matter with minimal biomass loss.

At the base of the rotary screen lies a screw conveyor, which facilitates the entry of biomass into the dryer system while decreasing any chance of cold air getting in. A receptacle called the "stone catcher box" is strategically positioned within the dryer piping, perching just below the point where the screw conveyor expels its contents. Only items that are of substantial weight such as stones and non-magnetic metals will deposit themselves within this designated container.

Our advanced biomass preparation system operates in three stages to guarantee that only pure, suitably-sized materials are conveyed into the drying section. This approach helps maintain optimal processing conditions and yields high-quality results.

Efficiently burning solid biomass fuels such as wood and briquettes, the hot air generator is crafted in a circular shape accompanied by refractory lining. The outer insulation lining limits heat loss, making it incredibly efficient. Heavy cast iron grating and feeding doors offer sturdiness to this already robust machine.

As it leaves the furnace, the flue gas passes through a refectory-lined duct and commingles with fresh atmospheric air. By cooling down to roughly 350-400 degrees Celsius, this thermal combination facilitates efficient flash drying processes.

The drying section consists of:

Cage mill: A machine called the cage mill has the ability to break down biomass into small particles. This device also ensures that there is enough turbulence to thoroughly mix the hot gas/air mixture with wet biomass.

Uniform Mix:Through a solid fuel fired furnace, a uniform mixture carries the wet biomass pneumatically through vertical pipes referred to as drying columns. By means of the hot carrying flue/air mixture and close interaction with the wet biomass, an intimate mixing process is facilitated that achieves effective drying.

Cyclone separator: A cyclone separator with high efficiency is employed to separate the biomass flow from the exhaust flow.

Rotary airlock: To efficiently remove dry biomass from the cyclone, a rotary air lock is employed. This equipment also serves to prevent any unwanted infiltration of air into the system.

ID Fan: To effectively remove the exhaust from the cyclone, an ID fan is utilized to draw it out and then discharge it into the atmosphere via a stack that stands 20 feet tall.
