摘要:
A low-temperature drying apparatus 10 includes a furnace body 12, a sheet 20, an infrared light transmitting plate 30, a supply device 40, a discharge device 45, and infrared heaters 50. The sheet 20 holds a coating film 22, which is an object to be dried, so that the coating film 22 is placed in the furnace body 12. The infrared light transmitting plate 30 is provided on a surface of the furnace body 12 that faces the sheet 20. The supply device 40 and the discharge device 45 generate a cooling flow in a space between the coating film 22 and the infrared light transmitting plate 30. The infrared heaters 50 are disposed to face the infrared light transmitting plate 30 in the open space OP outside the furnace body 12.
摘要:
The subject matter of the invention is a method for drying and thermal stabilization of biological material, including plant material seeds, sesame especially, in which purified material is placed in a drier chamber and subject to drying in a fluidized bed and subject to an infrared radiation, characterized by that the drying process is conducted in temperatures from 110 to 200°C with a gas stream velocity in the fluidized bed from 0.8 to 8 m/s above the sieve and in two stages lasting from 5 to 25 minutes. The gas used in the first stage is returned in 75% of the volume of entire portion of the gas used in this stage and moreover the infrared radiation of 0.8 to 6 µm wave length and adjustable electric power of an infrared illuminator (2) in range from 0.02 to 0.15 kW/kg of the material input is used. Whereas in the second stage drying is conducted with the total gas exchange and after the drying process the material is subject to immediate cooling to temperatures from 40 to 50°C and subject to thermo-biological stabilization. The subject matter of the invention is also an installation for drying and thermal stabilization of biological material, including plant material seeds, sesame especially, allowing for realization of drying according to the presented method.

摘要:
Device for drying seeds, in order to reduce their moisture content and, thus, improve their preservation conditions, wherein said reduction is based on the application of electromagnetic energy originating from the far-infrared region. The device comprises a hollow drum (1), with a horizontal axis (2) and an essentially cylindrical geometry, which rotates around said axis (2), with legs (3) and an opening (4) covered by an openable lid (5). The hollow interior of the drum (1) incorporates a horizontal support structure (7), which, in turn, comprises an upper side (8), with an essentially pyramidal geometry, and a flat lower side, wherein an emitter (9) that emits electromagnetic energy in the far-infrared region is placed.
