    摘要: The invention relates to a method and a feeder for increasing the efficiency of the expanding and drying process of organic plant materials, particularly in a jet dryer used for comminuted organic plant materials, particularly tobacco materials. The dryer works with the use of a gaseous expanding and/or drying agent under an absolute working pressure in the range from 2.5 kPa to 10 MPa. Preferably, overheated steam is used as the gaseous working, expanding and/or drying agent, and during transporting the material (1) from the feeding zone (6) to the zone (9) of the contact with the expanding and/or drying agent, a feeder, preferably a rotary vane feeder (4) is flushed, preferably in a continuous manner, with a gaseous medium (11, 12) which is capable of absorbing moisture, under an absolute pressure from 2.5 kPa to 10 MPa, the temperature of the gaseous medium (11, 12), preferably air, is from 50 to 200°C, and residues of the process gas are removed from the rotary vane feeder (4). Openings (5, 7) are formed in the housing of the feeder according to the invention, delivering the gaseous medium to the moving spaces between the vanes (3), as well as openings (5A, 7A) leading out the gaseous medium from the moving spaces between the vanes (3), the openings (5, 7, 5A, 7A) being arranged respectively in the walls of the housing of the feeder (4).

    摘要: A pulveriser (10) is disclosed which comprises a fan (12) which sucks air through a pipe (28). A hopper (42) receives material which is to be pulverised, the hopper (42) having an open lower end which communicates with the pipe (28). Between the hopper (42) and the fan (12) there is a venturi (36). Air flows through the venturi (36) at a speed of Mach 1 or above. Pieces of frangible material dropped into the hopper (42) are sucked to the venturi (36) where they are blown apart and reduced to powder.

    摘要: The apparatus embodies a feeding device (1), which conveys the paste/fibrous feeding material into a rotating disintegrator (4). In the under part of the apparatus the drying gasses (6) are being introduced and passed upwards through the slot (8) and into the disintegrator housing (4). The drying chamber has a conical shape with the point towards the outlet for the drying gasses (14), where the symmetrical rotating layer of powder (16), because of the rotation of the disintegrator (4), is being pressed by the wall of the cone (12) away from the the outlet for the drying air (14) with a resulting accelerating force (13) which is greater than the force of gravity. The symmetrical rotating layer of powder (16) is being held in position during the stay in the drying/floating zone (5). The finally dried material and the spent drying air is being discharged through the product outlet (17) and (18) in the upper part of the drying chamber.
    A step 2 air volume (9), which has a for the particles moderate temperature, is being blown from the ring chamber (10) through slots or nozzles (11) into the drying/floating zone and can for this reason gently after dry the symmetrical rotating layer of powder (16) as in a fluid bed.

    摘要: An improved two-stage comminuting and dehydrating system is efficient, environmentally sound, and may be employed to process sticky materials. The system includes a pair of cyclone structures (303,305) for comminuting and dehydrating. Injection ports (329) are positioned for injection of viscid substances directly into the low pressure region of each cone. The secondary cyclone structure (305) is equipped with a lower exit port. A single blower (307) is coupled with the cyclone structures to form an air flow loop (331,333) from the primary cone bottom to the secondary cone top and from the secondary cone top to the primary cone top. Airflow for cycling material between the cones is controlled by feedback from moisture and particle size monitoring devices in a collection unit coupled with the secondary cone.
