Vegetables ready to be consumed with our desiccant dehumidifiers

Nowadays, it is very common to find that supermarkets offer vegetables that are ready to be consumed, with no washing and preparation necessary. This makes the packaging process of greater importance than ever. Desiccant dehumidifiers are used to supply dry air at low temperatures, after washing, and before packaging, to avoid the formation of a water film on the surface of the product. This provides the following advantages:

  • Increased productivity.
  • Colour retention.
  • More natural taste and texture.
  • Lower risk of mould and yeast formation.
  • Improved energy efficiency.

Humidity control for packaging frozen vegetables

Frozen vegetables are packaged by volumetric packaging equipment that dispenses the product in a container. Condensation can occur when frozen vegetables are transported to the packaging area, through areas that have a higher dew point than the product temperature, or when the packaging machinery is in a high dew point area. This condensation forms ice in the filling area, making it difficult to accurately fill containers with the correct weight. Desiccant dehumidification in this area has the following advantages:

  • Increased productivity.
  • Improved weighing accuracy.
  • Reduced maintenance of the packaging and transport system.

Proper drying of fruit and vegetable powder with desiccant dehumidifiers

Fruit and vegetables such as tomatoes are turned into powder for multiple uses in the food industry. They are converted into juice and then filtered to remove seeds and fibres. The juice is concentrated, until it becomes a paste, before being introduced into the atomization tower. Please refer to the specific section on drying in spray towers and fluid beds for more on the contribution of Fisair desiccant dehumidifiers.
