The BST Hopper Dryer provides uniform hot-air drying for plastic granules before molding. Its stainless-steel material-contact construction, precise P.I.D. control and broad capacity range support clean, stable and efficient production.
Standard Configuration
Product Configuration
Equipped with a high-performance hot-air diffusion system to ensure even drying temperature and improve drying efficiency.
Curved hot-air pipe design prevents dust and material fines from accumulating around the heating elements and causing burning.
The hopper and all internal parts are made of stainless steel to prevent material contamination.
The hopper is separated from the material bin for easy cleaning and quick material changeover.
All models are equipped with an externally mounted power switch.
For BST-25 to BST-150 models, the heating elements use aluminum-fin connections. Other models are equipped with temperature protection devices to prevent heater burnout caused by blower failure.
Equipped with over-temperature protection. When the drying temperature exceeds the preset deviation limit, the main power supply is automatically cut off.
Uses a heat-insulated blower to extend machine service life.
All models are equipped with a standard 24-hour timer.
All models use a P.I.D. controller for intuitive and convenient operation.
