The Superheated Steam Vacuum Dryer was first introduced to the North American market by Vacutherm in 1980. This system utilized a discontinuous vacuum, which includes a conditioning cycle for hard to dry species. In this process a vacuum would be drawn on the chamber and then periodically brought back to atmospheric pressure, during which point fans would begin circulating hot air between the piles. This method is able to dry 3 – 5 times faster than conventional methods and requires that the lumber be stickered and loaded similarly to a conventional kiln. Today Vacutherm produces the AirVac dryer as a continuous vacuum kiln which may be built with up to a 40,000 Board Foot Capacity.
All Vacutherm kilns now use the new TOUCHDRY® kiln control system. This system integrates a wireless moisture meter, EMC and a 8.4″ color touch screen for simple to use and accurate controls, made for any operator to use with very little training.
Easy To Use
Kiln operators will wonder why is took this long to get a kiln control that just works and doesn’t take a computer programmer to run.
