Description

. 12

The invention relates to the brewing industry, in particular to installations for grinding malt in the process of preparing a mash.

The aim of the invention is to increase plant capacity.

FIG. I depicts a setup for crushing the malt; in fig. FIG. 2 is a section A-A in FIG. 1; FIG. 3 is a section BB in FIG. one,

The malt crushing unit contains a hopper 1, a feeder 2, a crushing unit 3, a pump 4. The feeder is equipped with an actuator 5, and in the feeder itself is installed vertically conical. screw 6, the screw surface of which has a variable pitch. The lower part of the side surface of the feeder body is made of a team of profiled Rods 7, arranged with a gap, the value of which is determined by the allowable thickness of malt particles in the gate, while some of the rods have channels 8 for supplying pressurized malt to clean the gaps, . ,

The screw 6 has a hollow shaft 9; The crushing device consists of two cones - a rigidly fixed cone 10 and a cone 11, installed with the possibility of movement along the axis of the hollow shaft 9, and equipped with a mechanism 12 for adjusting the annular gap between the cones 10 and II,

The drive 5 of the feeder rotates the hollow shaft 9 by means of the worm gear 13 from the electric motor (not shown). The shaft 9 is mounted in bearings 14 and 15, which accept radial and axial loads.

The movable cone 11 is mounted on the shaft 9 by means of the movable spline connection 16, which provides the movement of the cone 11 along the axis of the shaft 9 and the transmission of torque from the shaft to the cone. In the lower part of the cone 11, the base plate is fixed

17 with a central hole for ti gi

18 and holes 19. At the bottom of the rod 18, with a nut 20 with a washer 2I, the support plate 17, sleeve 22, paddle stirrer are fixed

23, the T of ha 18 passes inside the hollow shaft 9 and is centered relative to it from below by the support plate 17, and over the top by the sleeve 24. In the upper part of the ha ha 18 is connected with the mechanism 12 for adjusting the annular gap between the cones

10 and II through the spherical washers 25, the thrust bearing 26 and the nut 27. The lever 28 is mounted to rotate around the axis 29 of the rack 30. The other end of the lever 28 rests on the nut 31 moved by the screw 32 by means of the steering wheel 33. The screw 32 rotates in the supports 34 and 35. The installation is equipped with cHCTBHai iH pipelines 36 and 37 for supplying water and a receiving bin 38.

The installation works as follows.

Pre-moistened malt from the hopper 1 enters the feeder 2, the screw 6 of which forcibly moves the malt to the bottom of the feeder. In this case, malt is crushed between the turns of the screw and the feeder body and the pasty endosperm of malt is squeezed out through the longitudinal gaps between the rods 7 in the lower part of the feeder. The unsalted portion of the malt is forcibly fed between the cones 10 and 11, where it is ground. In the zone of the annular gap to press the working surfaces and increase the intensity of the malt crushing process, pressurized water is supplied through the pipeline 36. The mechanism 12 adjusts the size of the annular gap between the crushing cones by means of the pull 18. When crushing, the annular gap filled with malt fulfills the purpose of the lower shaft bearing 9. The ground malt flows by gravity into the receiving hopper 38, where it is stirred with water by the stirrer 23 and then fed into the mash tank. The pump 4 pumps out of the hopper 38 a portion of the water through the pipeline 36 to flush the gaps between the rods 7 and the working surfaces of the cones 10 and 11. The crushed malt particles that fell inside the cone 11 through the gaps in the spline joint are removed through the hole in the I7 slab

shaft 9 with a cone 11.

In the installation of malt repeatedly

crushed. First, between the turns and the feeder bodies, then it is forced through the gaps between the core rods installed in the lower part of the feeder body, and is crushed when pressed through an annular gap between the crushing cones. The annular gap between the crushing KOHycat-sh has a greater length, which allows for high performance crushing of malt.
