In a process, the humidity of at least the exhaust air is measured and used for the regulation of the product humidity of water activity during a treatment process. Therefore, it is possible to directly register the humidity taken on by the inlet air or charged onto it, and to draw a conclusion about the humidity content of the product. To register the humidity value, a measuring device with moisture testers in the inlet air channel and in the exhaust air channel is provided. Especially the moisture tester for the exhaust air is constructed as a bypass flow moisture tester in an intrinsically safe manner, so that it can be used even under ex-conditions. During drying procedures, the possible measuring of the humidity charge of the exhaust air from the drying process, the course can be exactly controlled. The moisture testers can be constructed as dew point testers, especially with capacitive measuring probes.

A method for supervising and/or guiding of physical treatment processes and bioreactions in ventilation systems, in which inlet air or gas is fed in and exhaust air or gas is expelled, and in which a product is being processed, said method comprising the steps of: establishing a fluidized bed in which the product to be treated is suspended by a flow of fluidizing inlet air supplied to a vessel; spraying an aqueous solution on the product while it is in the fluidized bed; measuring the humidity of the inlet air; measuring the humidity of the exhaust air; comparing the humidity of the exhaust air with the humidity of the inlet air; and altering certain process conditions, including at least one of the quantity of spraying solution, the temperature of the inlet air, and the volume of inlet air, the alteration of process conditions based on the humidity comparison to regulate the humidity of the product being processed, wherein the altering step is carried out to first alter the quantity of spraying solution, then the temperature of the inlet air, if necessary, and then the volume of inlet air, if necessary in that sequence, to regulate the humidity of the product being processed.
