Abstract

FIELD: food-processing industry, in particular, meat and fish fine grinding equipment.

SUBSTANCE: cutter has bowl, shaft with set of knives, cover, sealant, and drive. Cutter is further provided with device for splitting and suppressing turbulence of liquid farce flow, said device being rigidly attached to horizontal strip of knife cover. Said device has at least two vertical guides arranged along concentric bowl circles and extending to distance less than or equal to one quarter the length of its circle and overlapped at the top with plates. Guide of larger diameter is spaced from terminating knife of said set by distance corresponding to thickness of knife set, and each subsequent guide is positioned in offset relation with respect to previous one by value equal to doubled thickness of knife set.

EFFECT: increased efficiency by eliminating the possibility of farce losses owing to splitting and suppressing of farce flow turbulence.

Description

The invention relates to the food industry and can be used for fine grinding meat and fish to obtain pasty minced meat.

Known cutter, comprising a housing with a bowl placed in it, a knife head, a cover of a knife head and its fixation unit. A fluoroplastic ring is placed on the edge of the bowl (USSR AS No. 1688921, В02С 18/06, dated September 19, 89)

The disadvantage of this cutter is that when cooking pasty and liquid minced meat, the minced meat leaks through the knife cover.

Closest to the claimed device is a cutter containing a bed, a base with a lid, a bowl with an O-ring, a knife shaft with a lid and a seal, and a drive. The blade shaft cover is equipped with an arcuate scraper with a protrusion (AS No. 1629097, В02С 18/08, dated December 26, 88).

A scraper with a protrusion does not eliminate leaks for the preparation of pasty and liquid minced meat.

The technical task of the inventive cutter is to dissect and suppress the turbulence of the flow generated during the preparation of liquid and pasty minced meat in the grinding zone.

The specified technical result is achieved by the fact that the known cutter comprising a base, a bowl, a shaft with knife packages, a cover and a seal and a drive is equipped with a device for dissecting and suppressing turbulence in the flow of minced meat, rigidly attached to a horizontal shelf of the knife cover, containing at least two vertical guides located on concentric circles of the bowl with a length less than or equal to a quarter of the circumference of the bowl, and overlapped by plates on top, while the guide is larger diameter spaced from the last of the knife at a distance corresponding to the thickness of the knife package, and each subsequent guide is mounted to be offset from the previous one by two thicknesses of knife package.

Vertical guides installed with an offset relative to each other cut through the entire turbulent flow of minced meat, and the overlap from above suppresses flows, in addition, the guides with overlap form channels for free passage of minced meat.

Figure 1 shows the cutter, a General view, figure 2 is the same, a top view, figure 3 is a device for cutting and suppressing the flow, top view.

The cutter contains a base 1 with a bowl 2 placed on it, a shaft 3 with knife packages 4, a hinged lid 5 and a seal 6, a drive 7. A device 9 for dissecting and suppressing the turbulence of the liquid mincemeat is rigidly attached to the horizontal shelf 8 of the lid 5 vertical guides 10 and 11 located on the concentric circles of the bowl 2 with a length of less than one quarter of its circumference. The guides 10 and 11 are covered from above by the plates 12, forming channels for the free passage of the forcemeat stream. The guide 10 is spaced from the last knife of the knife package 4 by a distance L equal to the thickness of the knife package, and the guide 11 is offset from the guide 10 by a distance equal to 2L. This arrangement of the guides ensures the normal operation of the knife package and the complete suppression of turbulence in the flow of meat.

For high-performance cutters and large bowl volumes (≥250 liters), fixture 9 may contain three or more vertical guides.

Cutter works as follows.

When the lid 5 is closed, the components of the crushed raw materials are loaded into the bowl 2, the cutter is turned on, the bowl 2 and the knife package 4 are rotated, as a result of which the minced meat is ground and mixed. In the preparation of paste mincemeats, which are semi-liquid in structure, a turbulent swirl of the exit stream occurs at the exit from under the knife package, which is dissected by the guides 10 and 11, and suppressed by the plates 12 from above, then the dissected stream freely passes through the channels formed by the guides 10, 11 and ceilings 12, excluding the discharge of minced meat from the bowl of the cutter.

Using the proposed technical solution will eliminate losses in the preparation of semi-liquid and liquid minced meat.

Claims (1)

A cutter containing a base, a bowl, a shaft with a knife package, a cover and a seal and a drive, characterized in that it is equipped with a device for dissecting and suppressing turbulence in the flow of minced meat, rigidly attached to a horizontal shelf of the knife cover, containing at least two vertical guides located along concentric circles of a bowl with a length of less than or equal to one quarter of its circumference and overlapped by plates on top, while a larger diameter guide is spaced from the last knife the package at a distance corresponding to the thickness of the knife package, and each subsequent guide is installed with an offset relative to the previous two thicknesses of the knife package.
