SU1565399A1 - Device for disintegrating and drying raw materials in producing meat and bone meal - Google Patents

Abstract

The invention relates to the production of feed meal and can be used in the meat, food and feed industry. The purpose of the invention is to increase productivity, improve the quality of the finished product and increase the service life of working bodies. The device comprises a housing 1 with inlet pipes 2 and 3, respectively, for feeding material and a drying agent, an outlet pipe 4. The housing 1 is divided into coarse and fine grinding sections by a partition 5, which are connected via pipe 6 for material supply and have pipe 7 for additional drying agent. In case 1 a shaft 8 is placed, on which disks 9 with fingers 10 pivotally mounted along a helical line are fixed. The baffle elements are fixed on case 1 and made in the form of a comb, the height of each tooth of which increases in the radial direction. When the material is moved by the screw 13 to the coarse grinding and drying zone, it is crushed in the gaps between the crushing edges of the fingers 10 and the teeth of the comb. The material is dried, giving away its moisture to the drying agent entering through the nozzle 7. The finally crushed and dried product is carried away through the outlet 4 to the precipitation system. 1 hp f-ly.

Description

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

The purpose of the invention is to increase productivity, improve the quality of the finished product and increase the service life of working bodies.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows the node I in FIG. 2

The device for drying and grinding the raw material in the production of m flour flour consists of a body 1 with inlet pipes 2 and 3, respectively, for raw materials and a drying agent and an outlet pipe 4 divided by partitions 5 into sections communicating with pipe 6 for the passage of material, and have a pipe 7 for additional supply of drying agent. In the housing 1 there is a shaft 8 on which disks 9 with hinged fingers 10 are fixedly mounted. Fingers 10 on disks 9 are arranged one after the other along a helical line and form a single-phase auger of oncoming movement with respect to the product flow and drying agent. On the inner surface of the housing 1, on the opposite sides, there are baffle elements made in the form of a comb 11, the height of each tooth of which increases in the radial direction. On both sides of the comb 11, adjusting bolts 12 are installed to adjust the coaxiality of the pitch of the teeth of the fender elements 11 relative to the fingers 10. The distance between the crushing faces of the teeth of the comb 11 and the fingers 10 provides the necessary clearance corresponding to the desired grinding. The crushing faces of the comb 11 and the fingers 10 are coated with a protective wear-resistant material made of heat-treated steel grade ZOH GSA. In the receiving part of the housing 1 against the inlet nozzle 2, a single-step auger coil 13 is installed on the shaft 8, which provides the feed to the crushing and drying zone.

The device works as follows.

Juice raw materials dried in vacuum-horizontal boilers m with a water content of up to 55% to the total mass flow from the dispenser to the nozzle 2 and through the nozzle 3

A drying agent-hot air is supplied with a temperature of 190-220 ° C. The raw material of the auger coil is moved continuously to the zone of coarse crushing and drying, crushed in the gaps between the crushing edges of the fingers 10 and the teeth of the comb 11, and during the course of the Material and the drying agent, the grinding occurs more intensely by increasing the surface of the grinding edges. The raw material is dried, having given up its moisture to the drying agent, and is carried along pipe 6 to the zone of small

grinding and drying, then the material is crushed and dried, giving up its moisture to the drying agent entering through the additional pipe 7. The finally crushed and dried product is carried away through the outlet 4 to the system
