Advanced roller dryer veneer MC control using EUNIAN's proprietary MC3168 capacitance sensor — calibrated to the ASTM-D4442-20 international standard. Three intelligent speed modes deliver perfect moisture balance every time.
Drying is a critical process in plywood manufacturing, where inconsistent moisture levels compromise bonding strength, product quality, and on-grade ratio. The GENUS-306i is EUNIAN's roller dryer MC control system — combining the proprietary MC3168 non-contact capacitance sensor, in-house developed control hardware, and intelligent speed control software.
The MC3168 sensor measures the dielectric properties (ε) of each veneer sheet — a physical property directly proportional to moisture content. This capacitance-based, non-destructive, contactless measurement method is calibrated to the ASTM-D4442-20 international standard, ensuring factory results that are not merely theoretical.
The result is uniform drying, reduced energy consumption, and improved roller dryer throughput — with up to 15% increase in usable output reported by clients within the first three months.
Five integrated measurement and control stages running simultaneously — from veneer entry to marked wet-sheet output.
The proprietary MC3168 capacitance sensor measures each veneer sheet's dielectric constant (ε) as it exits the roller dryer — a non-contact, non-destructive read at full production speed.
The control card converts the 0–5.0Vdc analogue sensor output into accurate MC% readings — calibrated to ASTM-D4442-20 and verified against the Laboratory Validation Module for factory-grade accuracy.
Using the selected speed intelligence mode (Average, Calculated, or Smart Advanced), the system automatically adjusts roller dryer conveyor speed to maintain target MC output continuously.
When a veneer sheet is detected as under-dried, the GENUS-306i triggers the high-speed Veejet spray nozzle in milliseconds — physically marking the wet area for immediate visual identification and re-routing.
Full production data is logged — incoming MC, output MC per sheet, dryer speed, and wet-sheet rate — enabling management reporting, energy efficiency analysis, and continuous process improvement.
EUNIAN's proprietary sensing technology bridges the gap between laboratory precision and factory performance — certified and proven on the shop floor.
The MC3168 operates on capacitance-based sensing, measuring the dielectric properties (ε) of veneer. Because dielectric values are directly proportional to moisture content, this method offers a non-destructive, contactless solution — essential for maintaining the physical integrity of premium veneers.
The MC3168 capacitance sensor detects moisture levels with industrial accuracy — ensuring veneer never leaves the roller dryer too wet or too dry, regardless of species or thickness.
Average, Calculated, and Smart Advanced modes give operators the flexibility to choose their level of automation — from stable fixed-window averaging to full AI self-optimisation.
By optimising the drying curve and eliminating over-drying, the GENUS-306i reduces unnecessary thermal energy loss — clients report significant fuel savings alongside the 15%+ output improvement.
When under-dried sheets are detected, high-speed Veejet nozzles mark the problem area in milliseconds — enabling downstream operators to visually sort wet sheets without moisture meters.
The same MC3168 hardware used in the factory is replicated in a lab-grade validation unit — enabling quality managers to independently verify production MC readings against ASTM-D4442-20.
EUNIAN provides complete on-site installation, commissioning, and operator training in 22 countries — ensuring your team is running at full confidence from day one.

GENUS-306i controls your roller dryer — pair it with these systems for full-line veneer quality intelligence from drying through to stacking.
GENUS-306i controls roller dryers; EN-303 controls net/continuous dryers. Use both to cover every dryer type in your mill with the same AI precision and unified reporting.
Deploy the VMA-312 at dryer output for dual-head MC profiling and auto wet/dry sorting — complementing GENUS-306i's Veejet marking with automated stacker routing for complete sheet segregation.
After GENUS-306i ensures correct MC, deploy iPAWS-3 downstream to grade dry veneer surface quality — combining moisture and surface defect data for complete quality-by-grade stacking.
