Producing dry products from plant sprouts and/or seedlings and/or plants in early growth phase and/or its parts e.g. stem by applying selectively transformed infrared radiation, comprises heating and then cooling plant material to be dried

摘要

The method for producing dry products from plant sprouts and/or seedlings and/or plants in early growth phase and/or its parts e.g. stems by applying a selectively transformed infrared radiation (4), comprises heating a plant material to be dried at 50-70[deg] C, cooling the plant material in specified temperature region, and drying the plant material in vacuum at -15[deg] C to 40[deg] C with pressure of 10-500 mbar. An inert gas is guided over the plant material. The plant material attains maximum temperature of 40[deg] C, which is increased in dependent of the removal of residual moisture of the material. An independent claim is included for an arrangement for producing dry products from plant sprouts and/or seedlings and/or plants in early growth phase and/or its parts by applying a selectively transformed infrared radiation.
