CHAMBER DRYERS

B&T White chamber dryer guarantee:

a)      High flexibility

The programming software allows the storage of several drying cycles studied according to the characteristics and the shape of the pieces.

b)      Reduction of drying cycles

The control and management of temperature, relative humidity and air velocity of the process, allow to reduce the times of the different phases of the drying process.

During the different phases, the dryer will manage the parameters according to the needs set:

a)         evaporation and shrinkage.

At this stage is possible:

1)   increasing the temperature according to gradients programmed and operate two different air process speeds

2)   maintain a very high relative humidity in the drying chamber

b)         stabilization

At this stage is possible:

1)   to fix drying temperature and  manage two different process air speeds

2)   to decrease the relative humidity in the drying chamber, according to the programmed values

c)         final evaporation

At this stage is possible:

1)   increasing the temperature according to the set gradients until maximum value is reached, maintaining it for the programmed time and manage two different process air speed

2)   reduce the relative humidity in the drying chamber up to 1% and maintain it for the programmed time

The relative humidity in the drying chamber, is kept high with the complete air recirculation process.

The process air speed will be programmed to ensure a homogeneous shrinkage of the piece.

The control of temperature, relative humidity and the speed of the process is controlled and obtained by the programmer and by different regulators. In the execution of each cycle, control and security alarms are activated at each stage to evaluate the immediate process of any irregularities. The immediate control ensures the correct execution of the loop and allows any technical intervention by the staff in charge.
