Three-in-one Desiccant Dryer
·3‑in‑1 compact dehumidifying dryer is auxiliary equipment for injection and extrusion production. It integrates dehumidifying, drying and auto‑conveying functions in one unit, adopting honeycomb rotor to generate stable‑40℃ low‑dew‑point dry air.
Ordinary hopper dryer only works for low‑moisture‑absorbing material such as PP and PE. For hygroscopic engineering plastics like PA, PC, PET, PBT, normal hot‑air drying cannot remove internal moisture, which will cause silver streaks, bubbles and cracking defects. This 3‑in‑1 unit can reduce material moisture to very low level for stable product quality. Closed‑loop design prevents re‑moisture absorption during material transfer. Compact footprint, easy installation, built‑in auto feeding to injection machine hopper, no separate auto‑loader required.

·Main Features
English
1. All‑in‑one integrated design: dehumidifier host, insulated drying hopper and two‑stage conveying system combined, save workshop space.
2. Honeycomb rotor provides stable‑40℃ low dew‑point air, reduce defects such as silver mark and bubble for hygroscopic plastics.
3. Double‑wall insulated down‑blow hopper, low heat loss and energy‑saving.
4. Closed circulation loop, avoid raw material re‑absorbing moisture from ambient air.
5. HMI touch screen control, parameter memory, fault alarm and multi‑safety protection.
6. Built‑in vacuum conveying, feed dried pellets directly to injection machine, separate auto‑loader is not needed.
