VK 981 Curing Computer is the most advanced
Fully Programmable Curing Computer in the market.
It is based on microcontroller's latest technology, equipped
with all necessary safety devices and software to ensure its
safe operation under difficult conditions.
VK 981 can be installed on any barn or retrofit Heat Exchange
supplied with 12 Volts AC or DC from transformer or battery
to control the Burner and fresh air damper's servomotor (
220V or 120V or 24V AC) through 10 Amps relays .
VK 981 is designed to precisely control.
Burner's operation &
Fresh air (Intake) Damper's operation
· In Manual Mode, where Operator changes the
Temp. settings
· Semi Automatic mode where Operator changes
only the Curing phase
· Or Fully Automatic mode where Computer advances
the whole Curing automatically.
VK 981 is built in a plastic casing (7" high x 5,5"
wide x 3,5" deep) and can be mounted on the front or
top of barn's electrical panel or directly on a barn's furnace
room wall protected from rain, water drops from condensation
and vibrations.
Computer's Front consists of :
a) Four displays that indicate the following temperature :
· DRY BULB Temperature
· WET BULB Temperature
· T.A. Temperature Advance (Rate of D.B. Temperature
Increase)
· DT (DELTA T) TEMPERATURE DIFFERENCE between
Lower & Upper tobacco tiers (between Incoming - Outcoming
air from tobacco mass in the barn).
b) One Selector (0-9)
To Select the desired Curing Phase or Operating Mode (by
pressing lower (+) or upper (-) button)
· No.0 for MANUAL OPERATION
· No.1 for COLOURING
· No.2 for WILTING
· No.3 for LEAF DRYING
· No.4 for STEM DRYING
· No.5 for CONDITIONING
· No.6 for AUTOMATIC OPERATION
