Zeodration by confinement

Zeodration is a dehydration technique using zeolites.

It revolutionizes the field of drying due to the great flexibility of the process, which makes it possible to adapt the treatment, in terms of pressure and temperature, to meet the quality criteria of the chosen products.

Zeodration is carried out at a “product” temperature between −20°C and +60°C. This makes it possible to operate without deterioration of the organoleptic qualities, while respecting the structure of the products.

Preserved aromas

Better quality

Zeodration by confinement ensures better quality since it fully preserves the aromas, colors, vitamins and antioxidants. this works between 5 and 40°C in order to protect the vitamins.

This technique is based on the use of vacuum, with the addition of energy, to extract water more quickly from a product for dehydration.

The process

The different stages of the process take place as follows :

The product is loaded into the enclosure (tank, churn, tunnel).
The enclosure is placed under vacuum and can reach pressures below 100 Pa.
The product is then treated at a positive or negative temperature depending on its sensitivity as well as the type of drying envisaged.
The duration of the cycle depends on the ability of the product to release water.
Once the desired residual humidity has been reached (it can be reduced to a value below 1%), dehydration is complete.
The vacuum is then “broken” and the product is discharged.
