The invention relates to the food industry, namely to its brewing industry, and can be used in the process of grinding malt in preparing mash.

The aim of the invention is to increase the productivity and quality of the product obtained.

FIG. 1 is a diagram of an installation for crushing malt; in FIG. 2, section A-A in FIG. one; FIG. 3 is a section BB in FIG. 2

The proposed installation consists of a screw feeder 1, in which a conical screw 2 is vertically installed, the screw surface of which has a variable pitch, a hopper 3 for malt locking, a crushing device 4, the Auger 2 rotates in bearings 5 and 6 from the drive 7.

The lower part of the lateral surface of the feeder housing 1 is made of a team of rods 8, which are spaced apart by a gap, while some of the rods have channels for supplying pressurized water to the malt by means of a pump 9.

Crushing device 4 is located under the feeder and consists of parallel guides 10 and profiled rods 11 perpendicularly located on them, the ends of which are interconnected by axes 12 with flanges providing free relative movement of rods 11. In this case, one of the extreme rods is fixed rigidly on the guides, and the other one has a rod 13 with an eccentric drive 14 for communicating the possibility of relative movement. One of the extreme rods is rigidly fixed on the guides, and the other has a connecting rod 13 with a drive 14 for communicating reciprocating movement. The malt is compressed by screw 2, pounded through the gaps between the rods 8 and crushed by crushing in the PD. Productivity is increased by increasing the length of the working slot, and quality is improved due to the low rate of plastic deformation at the site.

reciprocating motion.

The proposed installation works as follows.

Wet malt from the hopper 3 enters the continuous feeder 1. The screw 2 with a continuous screw surface of variable pitch, moving the malt to the bottom of the feeder 1, forces it through the gaps between the rods 8 and 11. At the same time, the malt is ground in the gap between the feeder body and the screw, as well as a result of intensive mixing and full compression by the screw 2. With a warning chain, the value of clogging the cracks with malt in the area of their location is supplied with pressurized water by means of tox 9. Large and hard particles of malt that have not passed through the cracks between the rods 8 are fed to the crushing device 4, where they are crushed by coiling between the rods 11, and fed into the mash tun.

The invention improves the plant performance by increasing the length of the working gap between the rods during crushing. In addition, the quality of the obtained product is improved, because crushing the malt occurs HF resulting in flattening at a relatively low rate of plastic deformation of particles, which prevents the destruction of more durable shells when intensive separation from them endosperm.
