The plants are dried in the drug house by the so-called condensation process. In this process the warm, moisture-laden drying air is cooled to below dew point. This leads to condensation of the moisture which can then be removed in liquid form. Some of the energy generated during this process can be returned to the air current. The average room temperature during the process is 25-35°C. The condensation process allows us to dry the plants as quickly as possible. This is very important for a high product quality.
