In addition, the granular particles in different processing chambers 1a, 1b, and 1c are not mixed.
  • the scraping plate 13a comes into contact with the surface 11 on the one end side in the axial direction of the rotary drum 1 (one end side of the processing chambers 1a, 1b, 1c) and reaches the initial position P1a.
  • the scraping plate 13a is moved along the axial direction of the rotary drum 1 until it is done.
  • the granular particles in the processing chamber 1a pass through the opening 13a1 of the scraping plate 13a.
  • the openings 12a1 and 12b1 of the separator plates 12a and 12b are disposed above, the granular particles in the processing chambers 1a, 1b and 1c are moved by the separator plates 12a and 12b and the slide plate 14. It is regulated and powder particles in different processing chambers 1a, 1b, 1c are not mixed.
  • the scraping plates 13a, 13b, and 13c in the processing chambers 1a, 1b, and 1c are moved from the one end side predetermined positions P1a, P1b, and P1c to the other end side predetermined positions P2a, P2b, and P2c.
  • the powder particles in all the processing chambers 1a, 1b, and 1c can be transferred in parallel.
  • the granular particles in the processing chambers 1a, 1b, 1c Passes through the openings 13a1, 13b1, 13c1 of the scraping plates 13a, 13b, 13c.
  • the return operation of the scraping plates 13a, 13b, and 13c is facilitated.
  • the particles in the processing chambers 1a, 1b, 1c are separated by the separator plates 12a, 12b and the slide plate 14.
  • the body particles are restricted from moving, and the powder particles in the different processing chambers 1a, 1b, and 1c are not mixed.
  • the above-described coating treatment by the coating apparatus of this reference example may be performed in a batch type (batch type) or a continuous type.
  • the coating apparatus of this reference example uses the scraping plates 13a, 13b, and 13c as boundaries, and the granular particles being supplied to the processing chamber and the processing chamber when the granular particles are transferred. Since it is not mixed with the granular particles being discharged from, it is suitable for continuous coating treatment.
  • the rotary drum has a circular cross-sectional shape, but the rotary drum may have a polygonal cross-sectional shape.
  • the scraping plates 13a, 13b, and 13c are restricted in relative rotation with respect to the rotating drum 1, but these are rotatable relative to the rotating drum 1 and the rotation drive mechanism 1k.
  • the openings 13a1, 13b1, and 13c1 are fixed at the upper predetermined positions H4a, H4b, and H4c except when returning to the initial positions P1a, P1b, and P1c.
  • the opening portions 13a1, 13b1, and 13c1 may be switched to the lower predetermined positions L4a, L4b, and L4c and fixed when returning to the initial positions P1a, P1b, and P1c.
  • the rotating drum 1 can be divided into processing chambers 1a, 1b, and 1c, and each can be individually rotated. Further, by providing the separation plates 12a and 12b to be rotatable relative to the rotary drum 1 and providing separation member switching means different from the rotation drive mechanism 1k, the opening 12a1 is used except when the granular particles are transferred. 12b1 may be fixed at the upper predetermined positions H3a and H3b, and the openings 12a1 and 12b1 may be switched and fixed to the lower predetermined positions L3a and L3b when the granular particles are transferred.
  • the diameter of the rotating drum corresponding to each processing chamber is different, but the diameter of the rotating drum corresponding to each processing chamber may be the same.

Abstract

Dispositif d'enrobage comprenant un tambour rotatif (1) doté d'une pluralité de compartiments de traitement (1a, 1b, 1c), et pourvu de plaques d'évacuation (6a, 6b, 6c) qui transportent des particules granulaires dans les compartiments de traitement (1a, 1b, 1c), vers les compartiments de traitement (1b, 1c) ou vers une zone d'évacuation (1g). Ce dispositif d'enrobage est en outre doté d'un moyen de commutation d'éléments de transport (10) qui commute la position des plaques d'évacuation (6a, 6b, 6c) entre une position de consigne au-dessus d'une couche granulaire (M) comprenant les particules granulaires, et une autre position de consigne située sous la position de consigne supérieure.
