Production capacity

The performance range of the facility is approximately 400kg of water evaporation per hour. Production capacity amounts to between 150 and 400 kg/h, depending on the properties of the product to be processed.

Flexibility and the wishes of the customer are a priority for us. Production campaigns from less than 100kg up to many tonnes can be handled without any problems.

The principle of spray drying

Drying is one of the oldest methods of conservation for foodstuffs. Spray drying effectively uses the principle of surface area enlargement. As a result of the atomisation of liquids, fine droplets are quickly and gently dried in the hot air stream.

The temperature of the hot air stream is between 150 and 230°C. It acts on the product for the duration of just a fraction of a second. As a result of the water evaporation, the powder particles cool off again almost immediately. Therefore, gentle drying of your products with no product-damaging effects is guaranteed.

Please read here for a detailed description of the spray drying method.

Advantages of spray drying

The advantages of spray drying are:

  • Drying and shaping of the particle in one step
  • Gentle drying of temperature sensitive products
  • Large product throughput
  • Continual process
