Description

one

This invention relates to the food processing and food industry.

A device for cutting the fillet into rectangular pieces is known, which includes a loading chamber, with internal frames with plate knives, a shaft with a crescent-shaped cutting knife fixed on it, and a fat feeding mechanism for flat-blades, steel, and a drive.

In order to increase productivity in the proposed device, the lard feed mechanism is located in the lower part of the casing and is made in the form of a corrugated drum installed with the possibility of rotation, iBO cavities of which are flexible elements for clamping the spur strips and reinforced on the shaft opposite to the Crescent-shaped cutting knife Additional po, in a form similar to the Basic.

For cutting Spits' layers of any size, the device is equipped with a cylindrical chamber for returning the fat layer to the loading zone, on the inner surface of which the spiral guide edges are fixed. Inside the cylindrical chamber, a rotary drum formed by bushings and elastic sprockets is installed. Corrugated and slewing drum mounted on the same axis, and between them is a knife with a concave cutting edge.

In order to enable the cutting of bacon layers of various thicknesses, the grooved baraba is installed with the possibility of swinging by means of a lever suspension connected

with a drive. In this case, the boot chamber is inclined.

FIG. 1 schematically shows the proposed device; in fig. 2 - lard feed mechanism to lamellar “ojam”; na

FIG. 3 - frames with plate-blades, side zid in the section; in fig. 4 - sickle knife; pas figs. 5 is a section along A-A in FIG. four.

The device includes a loading chamber 1, a casing 2 with located inside it

frames 3 with plate-blades 4, shaft 5 with a sickle-shaped cutting knife 6 fixed on it and a lard-feed mechanism for plate-blades, frame 7 and drive 8.

The lard feed mechanism is located in the lower part of the casing 2 and is made in the form of a rotatably mounted drum 9 that can be rotated. In the cavities 10 of the corrugated drum are flexible elements, such as springs And, for clamping

streamers On shaft 5 from the opposite

from the knife 6 side reinforced additional

knife 12, in a form similar to the main.

For cutting pork fat in any size

the device has a cylindrical chamber

13 for Returning the seam to the loading area. Spiral guide ribs 14 are fastened on the inner surface of this chamber. Inside the chamber 13 there is a rotary drum 15, formed by bushings and elastic sprockets.

The corrugated drum 9 and the rotary drum 15 are mounted on the same shaft, and between them is located the knife 16 with a concave cutting edge. In order to ensure the possibility of cutting fatty logs of various thicknesses, the corrugated drum 9 is mounted for swinging in the direction of arrow B by means of a lever suspension 17 around a fixed axis 18 connected to the drive 8 (see Fig. 1). In order to supply the cut pnc in the direction of arrow B to the cutting zone in the device between the lower part of the casing 2, the side plate 19 and the pnya part of the fixed knife 16 formed the channel a. The knife 6 closes with its rotation with a small gap the opening of the outlet channel a, which reduces the drag from the selection of the product being cut.

The cutting knife 6 and the corrugated drum 9 are rotated by hydraulic motors (not shown in the drawing), allowing the rotation speed to be varied over a wide range and thereby adjusting the degree of grinding of the product in accordance with the work of the production line.

The loading chamber 1 is inclined. To remove the finished sliced lard in the casing, there is an outlet nozzle 20.

The device works as follows.

The fat layer (scaffold) is loaded into the chamber I and under the action of its own weight slides along the inclined section of the channel and in the direction of the arrow G. Thanks to the jamming, the fat layer is tightened under the drum 9 and 15, meeting on its own way the sickle-shaped knife 16, which cuts off from him a strip of a given width.

The cut strip of lard under the action of the rotating corrugated drum 9, pressed by the flexible elements 11 TO to the bottom of the channel a, is fed further along arrow B for cutting into frames 3 plate knives 4, while the strip of fat is cut last into rectangular pieces, and the section The pieces depend on the set of blade knives in frame 3. Then the lard pieces are cut in the transverse direction with sickle-shaped cutting knives 6 and 12, and the length of the pieces is adjusted by changing the rotation speed or the number of the latter.

The fat cut into size rectangular pieces is unloaded with the help of a manipulating device (not shown in the drawing) in the direction of arrow D through the outlet nozzle 20 into the container or onto the conveyor belt (not shown in the drawing). In the following, the cycle repeats. To make it possible to cut rectangular-shaped lard pieces with relatively narrow strips of lard size equal to or less than the width of the channel a, the device eliminates the turning drum 15, the cylindrical chamber 13 with the ribs 14 and the knife 16 replaced by a rigid solid plate - without a hole in it shaft of corrugated drum 9.
