(5) DEVICE FOR PREPARATION OF FEED

one

FIELD OF THE INVENTION The invention relates to fodder production, in particular, to devices for preparing feed.

There are known devices for the preparation of food, including a vertical chamber having a loading and unloading neck with a mixing device 1.2 installed therein.

However, the operation of such devices does not provide effective treatment of the liquid fraction of the feed, which reduces the quality of the prepared feed.

The aim of the invention is to improve the quality of mixing feed.

This goal is achieved by the fact that the mixing tool is made in the form of parallel-mounted one above the other and mounted with the possibility of counter-rotation of the rods with perforated blades.

In this case, the pinwheel is attached to the blade adjacent to it by m partitions, and the holes on the blade are made outside the partitions and have a diameter increasing towards the periphery of the blade.

FIG. 1 shows a device for preparing food, a general view; in fig. 2 - turntable, front view; in fig. 3 - the same, side view.

The feed preparation device comprises a vertical chamber 1,

. 10 in which a mixing working body is arranged, made in the form of turntables 2 with blades 3 fixed on the shafts. The latter are parallel to each other.

IS

The drive of these shafts (not shown in the figures) is configured to rotate adjacent turntables in opposite directions. Adjacent blades of each turntable are connected by singing with pendant partitions 5, which together with the blades form a container. 6 holes are made on each blade, located outside

these baffles, and the diameter of the holes increases as they approach the outer edge of the blade. ) „

The device works as follows

During the rotation of the turntables, the raw materials are continuously loaded through the loading device and additional feed components are introduced through the device to introduce the components into the chamber. Until the first batch is reached, the feed of the unloading device does not work and ensures the tightness of the chamber. Steam with a temperature of 10011 and pressure 0,, 0 MPa is supplied to the device chamber through the steam system. When loaded, the raw material enters the space between the blades and moves in the capacity of the turntables at a speed of 0.10, 2 rpm. Upon reaching a certain angle of inclination of the blade, the raw material releases the upper turntable and lands on the blade of the lower turntable, which rotates in the opposite direction relative to the upper turntable. Such a rotational nature of the adjacent turntables allows an increase in the path of movement of the raw material and, thus, the effect of steam on the raw material without increasing the number of turntables, without increasing the height of the vertical chamber.

At each transfer of a portion of the raw material from the upper turntable to the lower one, its mixing and agitating occurs, as well as the interaction of the raw material with steam throughout the entire portion of this portion.

The presence of containers formed by adjacent blades of the turntables and transverse partitions contributes to the retention of the liquid fraction of the raw material, which increases the processing time. The holes in the blades of different diameters disperse the liquid into thin jets when the container is rotated, and then as the angle of inclination of the blade increases, the fluid is quickly released from the liquid.

also in the form of jets.

The number of turntables in the device and the number of revolutions is chosen so that when the first loaded portion of the raw material is reached

unloading devices, the processing of raw materials is over. This device is then put into operation, after which the feed preparation process proceeds continuously.

When using the device, the processing efficiency is improved due to better mixing and agitating of the raw material and its intensive contact with steam, as a result of

This increases the amount of feed units in the final product while reducing processing time. .
