TDA/TDB Double Hopper 3 in 1 Compact Dehumidifying Dryer
The TDA/TDB double hopper 3 in 1 compact dehumidifying dryer is an integrated system with two hoppers, capable of drying two different plastic materials simultaneously at different temperature settings. It retains all the core functions of a standard three-in-one system—dehumidification, drying, and conveying—while saving energy and space. This design is particularly suitable for multi-material injection molding, color changes, or small-batch production, offering advantages such as flexibility, high efficiency, and low operating costs.
Features
- 1. Double hopper 3-in-1 compact dehumidifying dryer.
- 2. Has all function of 3 in1 compact dehumidifying dryer.
- 3. Saves energy, saves space.
Dual Temperature Drying With Integrated Dehumidification
The TDA/TDB double hopper dehumidifying dryer features dual-temperature drying capabilities and utilizes a shared dehumidification and control system alongside intelligent temperature management technology. It efficiently processes different materials while preventing cross-contamination, delivering precise, stable, and energy-efficient drying and conveying.
Four Key Technologies For Efficient Drying
Designed for multi-material production requirements, the double hopper dehumidifying dryer Series delivers independent temperature control, stable dehumidification and intelligent process management.
Independent Two-Temperature Drying
Two independent hopper temperatures allow different materials to be dried simultaneously without cross-contamination, maximizing production flexibility and space utilization.
Integrated Dehumidification Structure
The dehumidification unit, drying fan and control system are shared, reducing equipment footprint while maintaining stable drying performance.
Smart Monitoring & Safety Protection
Touchscreen operation, scheduled power management, RS485 MODBUS communication and multi-level protection functions ensure stable operation and remote production management.
Uniform Airflow & Accurate Temperature Control
Lantern-style air outlets increase airflow coverage, while third-generation PID control and solid-state relay drive provide precise temperature regulation.
Wide Industrial Applications
Suitable for raw material drying and conveying in injection molding, extrusion, medical, food, optics, electronics and automotive industries.
Integrated Material Processing
Integrates drying, dehumidification, conveying and control functions with three-stage feeding capability for continuous production processes.
