Abstract

The invention is in the technical field of particles; more particularly, the invention relates to large agglomerate particles obtainable by spray-drying agglomeration.

First claim

1 - 13 . (canceled)

14 . A method for producing agglomerate particles having a mean size of greater than 200 μm, said method comprising the steps of:
(i) producing pulverulent particles by means of a spray-drying process, in a spray-drying agglomeration device having a spray-drying segment (A) in the upper region of a chamber for drying feed liquid sprayed by a feed liquid atomizer (Z 1 ),
(ii) spraying the pulverulent particles with a binder liquid, in an integrated fluidized bed (B) in the spray-drying agglomeration device, which bed is situated in the lower region of a chamber, in which region the powder of the spray-drying segment from step (i) is sprayed with a binder liquid by means of a nozzle or atomizer construction (Z 2 ) mounted at the bottom of the fluidized bed (B),
the particles being constantly kept in motion and whirled up during production.

15 . The method of claim 14 , wherein the spray-drying agglomeration device comprises a dam construction (G) which is integrated in the fluidized bed (B) and which is placed in front of the escape opening (H) to the zigzag classifier or an external fluidized bed.

16 . The method of claim 14 , wherein the nozzle or atomizer construction (Z 2 ) in the internal fluidized bed (B) consists of a ring line, the nozzles or atomizers being evenly spaced along the ring line, the nozzle or atomizerconstruction (Z 2 ) comprising at least 3 nozzles or atomizers and the nozzle or atomizer being a twin-fluid spray nozzle and the binder liquid from the nozzle or atomizer construction (Z 2 ) in the internal fluidized bed being sprayed from the bottom to the top.

17 . The method of claim 14 , wherein the spray-drying agglomeration device comprises a darn construction (G) which is integrated in the fluidized bed (B) and is placed in front of the escape opening (H) to the zigzag classifier,

18 . The method of claim 14 wherein the fine dust in the device that arises as a result of abrasion is returned to the headspace of the spray tower by the zigzag classifier or an external fluidized bed.

19 . The method of claim 14 , wherein the agglomerate particles are larger than 200 μm.

20 . The method of claim 14 , wherein the agglomerate particles are between 300 μm and 1000 μm in size.

21 . The method of claim 14 , wherein the dust value of the particles is less than 3, preferably less than 2.

22 . The method of claim 14 , wherein the bulk weight of the agglomerate particles is greater than 300 g/l.

23 . The method of claim 14 , wherein the flowability of the particles is less than 14.

24 . The method of claim 14 , wherein the agglomerate particles are present in a freeflowing, non-dust-raising form.

25 . The method of claim 14 , wherein the agglomerate particles are an intermediate product which is later incorporated into a feedstuff, food or foodstuff.

26 . The method of claim 14 wherein the particles are flavouring particles.
