Roller Type Veneer Dryer
The roller type veneer dryer is the standard solution for drying 1-3mm core veneer at high throughput. Veneer sheets travel between heated roller decks while hot air jet boxes dry both surfaces evenly, so boards come out flat and crack-free. Choose 2, 3 or 4 decks and 5-15 heating sections to match your capacity: a 4-deck configuration reaches about 4 m3/h drying output at 0-15 m/min line speed. Steam or thermal oil heating, large-area radiators and a unique jet box design keep moisture even across the sheet while cutting energy use by up to 25%. Optional automatic feeder, moisture detection and sorting integrate the dryer into a fully automatic line.

Frequently Asked Questions
Q:What wood species are suitable for this machine?
Hanvy machinery is engineered for both hardwoods and softwoods, including Eucalyptus, Birch, Radiata Pine, Poplar, Rubberwood, and tropical timber. The Siemens control system includes pre-configured recipes for various wood densities.
Q:What is the delivery lead time and export packaging standard?
Standard machines ship within 30-45 days; complete turnkey production lines require 60-90 days. All machined surfaces are treated with marine-grade anti-rust coating, plastic film wrapped, and steel-wire braced in standard 40ft HQ shipping containers.
Q:Do you provide on-site overseas installation and commissioning?
Yes. Hanvy has dedicated overseas engineering teams available to travel worldwide to your job site for foundation verification, machine erection, electrical cabling, and live trial peeling/pressing until full target capacity is achieved.
Q:What is the warranty policy and spare parts availability?
We provide a 12-month full machine warranty. Critical wear parts are stocked in our central warehouse and can be dispatched worldwide via DHL/FedEx within 24-48 hours. Lifetime 24/7 remote video and PLC diagnostic support is included.
