Definitions
- the respective drying process with the cheapest energy consumption is selected automatically, whereby between Cold air mode and recirculation mode is switched. Combinations are also possible.
- the total amount of outside air passed through the dryer is reduced and set to that amount that is necessary with minimal consumption of electrical energy to promote the air flow and with minimal consumption of primary energy or waste heat to heat the outside or recirculated air flow is.
- the air volume flows are adjusted / reduced in every operating state to such an extent that only the maximum volume flow required to convey the water to be evaporated is conveyed.
- the total air volume is reduced in cold air mode.
- the amount of fresh air is adjusted and reduced to the necessary level by means of the dryer in order to return sufficient heat on the one hand and to maintain a sufficiently high flow rate on the other hand, so that the mass transfer processes are supported.
- the necessary measure relates to the goods to be dried and the drying task (quantity, input, accept content, output solids content).
