Wood vacuum-drying plant | WTT Wood Treatment Technology

This plant is designed for using the super heated steam vacuum drying process (SSV). The SSV basic principle is to control the temperature and the pressure with the aid of steam pressure through which every desired relative humidity (balanced moisture) can be achieved. In order to control the process exactly, an absolute vacuum is necessary.

DSE: Lesson 6. Principle of drying
DSE: Lesson 6. Principle of drying

Water migration in foods is an important phenomenon in drying. During drying heat flows over the product and goes in to the product. This heat increases the temperature of product and moisture which converts the moisture in to water vapor which results in to increase in the vapour pressure that moves moisture towards the surface (Figure 6.5).
