ABSTRACT:
The vacuum contact drying takes place in a device with a horizontally-arranged heated cylinder (1), a stirrer circulating with a very small wall separation, a blade (4) arranged on the stirrer and optionally an injection line (6), also arranged on the stirrer, for the introduction of liquid, gaseous, or vaporized media. According to the invention, the drying may be controlled whereby the value for the product temperature, the vacuum and the instantaneous evaporation power are continuously measured and regulated on the basis of the measured values.
