Description

The invention relates to an operation to improve the quality of a meat or fish product before cooking. The main task for preparing a meat or fish product before cooking is to perform an operation due to which it is necessary to reliably cut the veins and hard fibers along the entire height of the meat or fish product with the established step of introducing vertically arranged cutting inserts into it with acute-angled or rounded cutting edges of the blades and multi-row alternating with each other, which introduces a certain character in the structural separation of parts of the meat product, regardless of possible accumulations veins of fibers and hard fibers in the processed medium.

The search for analogues did not lead to positive results due to the lack of such structures of the cutting tool.

The aim of the invention is to expand the technological capabilities of a manual cutting tool associated with improving the quality of preparation of a meat or fish product based on a statically determined depth of cutting of veins and hard fibers, which ultimately helps to achieve the ultimate goal.

The task is achieved in that the manual cutting tool (1) with cutting inserts of an acute-angled shape of the cutting blades (2 and 3), which are set in the static dependence of a certain step of the first row of vertices of the cutting blades and are successively shifted by half the vertices of the cutting blades (2) of the second a number of cutting inserts, determined for each subsequent pair of rows of the installed position of the cutting blades, with a statically defined distance between the rows of cutting blades, characterized in that the number of cutting inserts (2 or 3) They are made in the form of a flat comb insert (4), and this row is completed by performing the negative rear angles of the protrusions of the blades, which limit the total width of the comb insert (5) and weld into the groove of the holder (1) containing carbochain, heterochain, or organoelement polymers, which, with a decrease in the cooling rate of the welded joint, regulate the structure and properties of the weld joint, which is especially important for plastics that are used for contact with meat products, and the second holder (1) is made They are similar to the initial form of placing the vertices of the cutting blades on a flat cutting insert-comb with a constant thickness of the sheet profile in which the position of the vertices of the blades is shifted by half the set step, the lateral protrusions with negative rear angles of the second conditional row of protruding vertices of the cutting blades remain unchanged, and limit the size of the cutting insert -combs (5), at the same time repeat the execution of pairs of rows of holders (1) with cutting inserts-combs (4 and 5), adjust the distance between the rows of blades d (2) and (2-3) within the plane-parallel placement of the thicknesses of the holders, and the step of the arrangement of the acute-angled protrusions of the cutting inserts (2 or 3) is determined by fixing the holders (1) with threaded rods (8 and 9) and fix them with the bearing head area bolts (24) and the supporting surfaces of the wing nuts (10), resting on the surface of the holder (1), while the shape of the holders provide rounding profile handles (17-22), as well as shaped semicircular decorative grooves (13-16), while the number of holders (1) with cutting inserts (2) or (2 and 3) take from two up to ten or more, and the number of through holes overlapped by the surface of the comb-cutting insert (4 and 5) visually separating them is equal to two.

Manual Cutting Tool Description

Manual cutting tool (1) with sharp-shaped cutting inserts of cutting blades (2 and 3), which are statically dependent on a certain step of the first row of tops of cutting blades and sequentially offset by half of the tops of the cutting blades (2) of the second row of cutting blades, determined for each subsequent pair of rows of the installed position of the cutting blades with a statically defined distance between the rows of cutting blades, characterized in that:

- a number of cutting inserts (2 or 3) are made in the form of a flat comb insert (4) and this row is completed by performing negative rear angles of the ledges of the blades, which limit the total width of the comb insert (5) and weld into the groove of the holder (1) containing carbochain, heterochain or organoelement polymers, which, with a decrease in the cooling rate of the welded joint, regulate the structure and properties of the weld joint, which is especially important for plastics that are used for contact with meat products;

- the second holder (1) is performed similarly to the initial form of placing the vertices of the cutting blades on a flat cutting insert-comb with a constant thickness of the sheet profile, in which the position of the vertices of the blades is shifted by half the set step, the lateral protrusions with negative rear angles of the second conditional row of protruding cutting vertices remain unchanged blades and limit the size of the comb insert (5);

- repeat the execution of pairs of rows of holders (1) with cutting inserts (4 and 5), adjust the distance between the rows of blades (2) and (2-3) within the plane-parallel placement of the thicknesses of the holders;

- the location step of the acute-angled protrusions of the cutting inserts (2 or 3) is determined by fixing the holders (1) with threaded rods (8 and 9) and fix them with the supporting area of the bolt heads (24) and the supporting surfaces of the wing nuts (10) resting on the surface of the holder (one);

- the shape of the holders is provided with roundings of the handle profile (17-22), as well as shaped semicircular decorative grooves (13-16);

- the number of holders (1) with cutting inserts (2) or (2 and 3) is taken from two or more, and the number of through holes overlapped by the surface of the comb cutting insert (4 or 5) visually separating them is equal to two.

An example of a manual cutting tool.

Manual cutting tool (1) with sharp-shaped cutting inserts of cutting blades (2 and 3), which are statically dependent on a certain step of the first row of tops of cutting blades and sequentially mixed at half step of the tops of cutting blades (2) of the second row of cutting blades, determined for each subsequent pair of rows of the installed position of the cutting blades with a statically defined distance between the rows of cutting blades is performed in such a way that:

1) a row of cutting inserts (2 or 3) is made in the form of a flat comb insert (4) and this row is completed by performing negative rear angles of the protrusions of the blades, which limit the total width of the comb insert (5) and weld into the groove of the holder (1) ) containing carbochain, heterochain or organoelement polymers, which, with a decrease in the cooling rate of the welded joint, regulate the structure and properties of the weld joint, which is especially important for plastics that are used for contact with meat products;

2) the second holder (1) is performed similarly to the initial form of placing the vertices of the cutting blades on a flat cutting comb-plate with a constant thickness of the sheet profile, in which the position of the vertices of the blades is offset by half the set step, the lateral protrusions with negative rear angles of the second conditional row of protruding vertices remain unchanged cutting blades and limit the size of the comb insert (5);

3) repeat the execution of pairs of rows of holders (1) with cutting inserts (4 and 5), adjust the distance between the rows of blades (2) and (2-3) within the plane-parallel placement of the thicknesses of the holders;

4) the pitch of the acute-angled protrusions of the cutting inserts (2 or 3) is determined by fixing the holders (1) with threaded rods (8 and 9) and fix them with the supporting area of the bolt heads (24) and the supporting surfaces of the wing nuts (10) resting on the surface holders (1);

5) the shape of the holders is provided with roundings of the handle profile (17-22), as well as shaped semicircular decorative grooves (13-16);

6) the number of holders (1) with cutting inserts (2) or (2 and 3) is taken from six to seven, and the number of through holes overlapped by the surface of the cutting comb plate visually separating them (4 or 5) is two.

Economic advantages of a technical solution

An important factor in saving time is the autonomous separation of the holders when washing and sanitizing the blade tool after use, which allows access to each blade separately.
