How a GIRBAU dryer works

As a basic principle, air enters the dryer through a heating element which heats it to the desired temperature. The air is heated using various calorie-providing methods: steam, electricity or direct gas.

Inside the drum the linen moves as a result of the joint action of the rotation and the blades. In these movements the linen is suspended in the stream of hot air created.

The movement of the air generated causes the air to flow into the moisture-laden fibres.

Lastly, the moisture-saturated air passes through a filter system to capture the remnants of fibres and is extracted to the outside.

1 . Axial air flow movement 

Dry air enters through the rear of the machine where it is heated, entering the machine’s drum transversally and leaving at the front loaded with moisture. It then passes through the lint filter and is extracted to the outside.

Dryers with an axial flow system are equipped with a basket that has no perforations, since all the air flow enters through the bottom of the basket.

2 . Radial air flow movement 

Dry air enters through the bottom, passes through the heater and enters the basket through the space between the perforated basket and the drum.

3 . Diagonal radial-axial air flow movement 

There are dryers with different combinations of air flow, depending on the location of the heating element, the hole through which air enters and leaves the drum, etc. Basically they are no different from the types described above, being mostly construction variations of the dryer itself.
