Description

The LDT50/5D air drying tunnel was developed specifically for drying delicate salad leaves and for creating a low moisture percentage on the surface of the leaf.Before reaching the drying tunnel, the product goes through a preliminary de-watering step by means of a de-watering belt.

In the drying tunnel, the product is dried in an air stream that is oriented upwards, at a temperature of 25 to 30 ºC. The air speed is such that the product will float, causing as much moisture as possible to be released.

The air stream that is in circulation is cooled down in a heat exchanger to a temperature of approx. 5 ºC. Some of the water vapour is removed from the air stream because it condenses on the cold fins of the heat exchanger.

To enable the air to absorb moisture again, it is passed through a second heat exchanger where it is warmed up to a temperature of 25 to 30 ºC, lowering its relative humidity.While drying the product, the air cools down due to the evaporation of the surface water on the product. This effect keeps the product much cooler than the drying air.

The air is cooled down and warmed up by using a refrigerant of approx. 0 ºC and, respectively, 33 ºC.

The air drying tunnel enables moisture values of less than 2% on the surface of the product to be reached.

The LDT-50/5D air drying tunnel is equipped with it’s own cooling installation. No additional refrigeration is required.

Capacity – Up to 600 kg/h .
