Abstract

The invention relates to agriculture, in particular to feed production. The device comprises a cylindrical body in which a hollow shaft with discs and bills is placed. The disks are provided with channels communicating with the cavity of the shaft. Swirl blades are mounted on the disks, connecting pipes are mounted to move them in height. Zil.

Description

The invention relates to the production of feed flour and can be used in the meat, chemical, food and animal feed industry.

The aim of the invention is to eliminate the above disadvantages, namely: reducing energy loss and intensification of the drying and grinding process, as well as improving the quality of the dried product.

Figure 1 shows the proposed device; figure 2 - node B in figure 1; on figs - section aa in fig. 1.

The device for grinding and drying the raw materials in the production of moccum flour consists of a housing 1 with inlet pipes 2 and 3, respectively, the raw material and a drying agent and an output pipe 4.

The housing 1 is provided with transverse sealed partitions 5 dividing em into separate sections, additional nozzles b and connecting pipes 7 between the sections, which are adjustable in height, and also a nozzle 8 dl. supplying an additional drying agent to the drying zone.

A hollow shaft 9 with holes 10 is located in the housing 1; disks 11 with drills 12 are mounted on it and the disks have holes 13 for supplying a drying agent to the crushing zone, each disk having additional blades 14 for swirling. On each of the section's inner surfaces 1, baffle elements 15 are located, which correspond to rectangular profiles 12, whose height in the radial direction provides the necessary clearance to the crushing face 12 (in Fig. 3, section A-A).

In the receiving part of the housing 1 against the inlet pipe 2, a one-step turn 16 is installed on the shaft 9, which ensures the supply of raw materials to the crushing and drying zone.

At the exit from the last section, an iris diaphragm 17 is installed, changing its bore when turning the ring 18 with the handle 19. The inlet pipe 2 and the outlet pipe 4 are made in the shape of a cochlea.

The device operates as follows.

Dried raw materials in vacuum-horizontal boilers with a content of up to 55% humidity to the total mass are supplied from the batcher or directly from the grinder of the top (not shown) to pipe 2, and hot air with a temperature of 500 -600 ° C.

The raw material is conveyed by a screw coil 16 continuously into the crushing and drying zone, is crushed in the gap between the edge of the beat 12 and the chipping elements 15, is dried, passing its moisture to the drying agent, the transition of one section to the other (the drying speed decreases), and carried away through the holes the diaphragm 17 and the outlet pipe 4 into the deposition system.

To intensify the drying process, an additional drying agent is supplied through the hollow shaft 9 through the holes 13 in the disk into the crushing zone of each section, due to the blades 14 in the disks, the flow is twisted and swirled. To regulate the length of

The presence of particles of materials in the drying zone is additional. The connecting pipes 7 are height-adjustable and have nozzles 8 for supplying the drying agent to the drying zone.

The use of the device will increase the productivity of workshops for the production of m high-fat flour, improve the quality of the finished product.
