Definitions

• a device for desintegrating particulate material is provided.
• the object of the invention is to obtain a device suitable for desintegrating such particular material as oat-grains in such a way that the fluffy surface obtained by crushing and promoting growth of mite is eliminated. In this way, the food would maintain its nutritional valueand damages under storage would be reduced. Particularly important is to assure that the device will maintain its operational characteristic during prolonged periods.
• the shaft generally vertically so that not only the particles to be desintegrated but also the own weight of the disc will urge the same towards the cutting member. It would also be possible to arrange one or more springs to urge the disc towards the cutting members.
• Fig. 1 is a view of the device from above;
• Fig. 2 illustrates a vertical section of the device
• Fig. 3 is a plan view and a section of an apertured disc
• Fig. 4 is a plan view and a section of the cutting member
• Fig. 5 is a plan view and a section of an impeller for discharging the desintegrated oats from the device;
• Fig. 6 is a plan view and a section of an agitator; and Fig. 7 is a section and a side view of a drive shaft.
• a base plate 1 is rigidly connected to an upper frame plate 2 and a lower frame plate 3.
• the plates 2 and 3 are also rigidly interconnected by a vertical plate 4.
• the plates 2 and 3 have at portions spaced from the base plate 1 bea ⁇ rings 5a and 5b respectively in which the shaft 6 is rota- tably supported.
• a V-belt pulley 7 is rigidly connected to the shaft 6.
• the V-belt 8 surrounds pulley 7 and also a smaller pulley 9 which is rigidly con- nected to the drive shaft of a vertically disposed motor 10 on the vertical plate 4.
• the shaft (see Fig. 7) is provided with planar surfaces 11 and 12 located opposite each other.
• An agitator 13a is located axiallymovableon the shaft 6 near its upper end but locked against rotation to the shaft 6 in that the hub of agitator 13a has a center hole 13d (Fig. 6) corresponding to the shape of shaft 6 in this section.
• a disc 14 is located directly below agitator 13a and has a series of apertures 16 (Fig. 3) generally equally distri- ubbed over the surface and a center hole 15 allowing verti ⁇ cal movement as well as rotating movement relative to shaft 6.
• a star shaped cutting member or knife 17 (Fig. 4) is located immediately below disc 14.
• the knife has a center hole 18a, the form of which corresponds to the cross sec- tion of shaft 6. In this way, knife 17 may move axially on shaft 6 but is locked against rotation relative thereto.
• the knife 17 has long edges 18b and 18c moving closely adja ⁇ cent the lower side of the disc 14, which is preferable at low number or revolutions.
• an insert or shim not illustrated in the drawing and having a thickness of about 0,1 mm and shaped as a washer about shaft maybelocated between disc 14 and knife 17 to reduce friction.
• Another agitator 13a is located directly under knife 17 and under the agitator, another apertured disc 14 and knife 17 identical to those previously described are located.
• the agitator 13a, disc 14 and knife 17 form together a set which may be used singularlyortogether with other sets in a series in accordance with requirements.
• An impeller 19a is located beneath the last knife 17 and axially movable on shaft 6 like the discs 14 and knives 17 but locked against rotation to shaft 6 via the center hole 19b (Fig. 5).
• All agitators 13a, discs 14, knives 17 and the impeller 19a are enclosed in a vertical cylindrical drum 20 which is rigidly anchored to the upper side of the upper frame plate 2 , which at this location forms a bottom of the drum 20.
• an outlet tube 21 is tangentially fixed.
• a longitudinal vertical projection 22a is located, which is received in corresponding recesses 22b in the disc 14 so as to prevent the latter from rotating with the knive 17.
• a container 23 is located centrally above drum 20 and has in its lower portion a cylindrically formed part 24, in which a closure device 25 is located.
• the base plate 1 has at one of its vertical edges a hinge 30, one portion of which is anchored to e.g.
• a locking device 33 is arranged at the opposite edge of base plate 1 and this locking device is anchored to wall 31 by screws 34.
• the lock 33 is released so as to enable plate 1 to be rotated outwardly about its hinge 30.
• the outlet tube 21 will rotate from the position illustrated with full lines in Fig. 1 to the position illust rated with dashed lines and the upper part of drum 20 will be uncovered from container 23.
• the electrical connection of motor 10 is arranged so that the current connection 35 must be interrupted in order to open the lock 33 and release the frame for rotation so as to make discs and knives accessible
• the invention operates as follows: When the motor 10 is star ted, it rotates, through the V-belt transmission 7, 8, 9, the shaft 6 and the agitators 13a, knives 17 and impeller 19 in the same direction.
• the closure device 25 is open. Oat grains 26 will fall down and fill the open space at the top of drum 20. Due to rotation of shaft 6, the wings 13b, 13c of agitator 13a will rotate and feed the grains 26 through apertures 16 in disc 14 which is locked against rotation. When the oat grains 26 pass out of the apertures 16, they wil face the rotating knife 17 which by edges 18b or 18c will shear the oat grains 26 against the edges of apertures 16.
• the partially desintegrated grains 26 now enter the space below knife 17, wherein another agitator 13a with wings 13b, 13c agitates and mixes the material before it passes another disc 14 and knife 17 for additional desintegration.
• the grains 26 will subsequently fall down between the blades of the impeller 19a which rotates with shaft 6 and throws the oats out through tube 21 so that it in a gathered stream falls down into e.g. a receptacle 29.
• the number of discs and knives may be lower and higher than in the embodiment.
• the knives may be turned so that the direction of their shearing edges from the center towards the periphery alternatingly forms a positive and negative angle.
• agitators between apertured discs and knives may be eliminated dispite use of several sets of discs and knives.
• a spacer ring may be used if so desired.
• the device may also be used for desintegrating other particulate mate ⁇ rial than oat grain.
