Polished SS Tray Dryer, Material OF Trolley : S.S 304

A tray dryer machine is an industrial, batch-processing oven that removes moisture from a wide range of products, including powders, granules, and pastes, by circulating hot air through stacked trays. It consists of an insulated cabinet containing trolleys with trays, a heating system (electric, steam, or fluid), a recirculating air system with a blower, and a control panel for setting temperature and time. The machine is known for its simplicity, cost-effectiveness, and ability to provide uniform, controlled drying for materials in industries like pharmaceuticals, food, chemicals, and cosmetics.  

Components and Design

Cabinet: A double-walled, insulated chamber designed to hold the heat and material trays. 

Trays: Stacked on trolleys inside the chamber, holding the material to be dried in a thin layer for efficient evaporation. 

Heating System: Sources of heat can include electric heaters, steam, or thermic fluid, with the heat transferred to the air circulating inside. 

Air Circulation: A fan system circulates heated air through the chamber and over the trays, promoting moisture evaporation and uniform drying. 

Control Panel: Features a digital temperature controller and timer to precisely set and monitor drying parameters. 

How it Works

Loading: Material is placed onto the trays, which are then arranged on trolleys and loaded into the dryer. 

Heating: The system heats the air to a set temperature, usually between 50 and 300°C. 

Drying: The heated air circulates around the trays, absorbing moisture from the product. The air is recirculated to maintain efficiency, with fresh air introduced only as needed. 

Unloading: Once the desired moisture content is reached, the trays are removed for the next batch or product handling. 

Key Features and Benefits

Batch Processing: The machine operates in batches, allowing for controlled and separate handling of each lot. 

Uniform Drying: The recirculating hot air system ensures even heat distribution, resulting in consistent drying across all trays and products. 

Wide Application: Versatile for various industries and materials, including pharmaceuticals, chemicals, food products, and cosmetics. 

Ease of Use: Simple to operate and maintain, making it an economical choice for drying needs.
