DRUM TYPE GRANULATOR Russian patent published in 2019 - IPC A01F15/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and is intended for the granulation of feed mixtures based on germinated grain. Granulator consists of receiving pipe (1), which is made removable and fixed to the side of conical matrix (2) with cone-shaped holes. Conical matrix (2) is made in the shape of a truncated cone. Pressing rollers (5) are made with the possibility of rotation around its axis and at the same time with the possibility of rolling along the inner surface of conical matrix (2). Granulator includes rotary knife (3), which is made in the shape of a truncated cone with holes. Rotary knife (3) is designed to allow the cutting of granules and is made with the possibility of rotation around the horizontal axis with the help of electric motor (4). Inner edge of the holes of rotary knife (3) is sharpened, gear (9) is provided to drive rotary knife (3). To drive knife (3), electric motor (4) and polyamide rim (8) are provided for rotation, which engages with gear wheel (9) mounted on motor shaft (4). Receiving hopper (13) is located below conical matrix (2). Pressing rolls (5) are mounted on carrier (6), which is fixed on shaft (12). Pressing rollers (5) with planet carrier (6) are made with the possibility of axial movement with the help of stepper motor (7). To allow pressing rollers (5) to move in the axial direction, shaft (10) is connected to shaft (12) by means of a spline connection. Rotary knife (3) is made with a gap 2…3 mm relative to conical matrix (2). To avoid blockage of granules at the exit from the hole of conical matrix (2), the diameter of the holes D of rotary knife (3) is larger than the diameter of the holes d of conical matrix (2) by 2…3 mm.

EFFECT: improving the performance of the granulation process of the feed mixture, controlling the density of the granules, reducing the cost of preparing raw materials for granulating.
