Description

Technical field

The utility model relates to machine tool industry for the food industry and can be used in the production of drum-type machines designed for the production of ravioli, dumplings and other similar products from dough with filling.

State of the art

Known drum dumpling machine (RU 2272410) comprising molding cells located at a predetermined distance from each other and facing the outer working cylindrical surface of the drum.

The disadvantage of such a drum is the dissimilarity of the conditions for forming dumplings for the external and internal cells of the drum.

The desire to place the cells as close to each other as possible (taking into account the requirement of additional filling with the test the place of impression of the test sheets, which ultimately determines the specified distance) leads to the fact that the cells are located on the drum in the form of honeycombs. In this case, the inner cell is surrounded on all sides by other cells, while on one side the outer cells do not have neighboring cells.

As a result: 1) the area of the working cylindrical surface of the drum surrounding the inner cell is smaller than that in relation to the outer cell and 2) the working cylindrical surface in the same way (symmetrically) surrounds the inner cell, while in relation to the outer one there is an imbalance, the result of which is excessive and uneven around the perimeter of the cell test pressure from the ends of the drum.

All this worsens the appearance of the finished product, eliminates the possibility of obtaining a symmetrical product, leads to a distortion of the shape of the impression site, in particular, “ears” are formed from the ends of the drum at the impression site.

Technical result

The purpose of the development of a utility model is to improve the appearance of products manufactured using the claimed drum, ensuring the possibility of manufacturing identical products.

The task of creating a useful model is to create the same conditions for forming dumplings with internal and external cells.

The technical result achieved by the implementation of the main distinguishing features of the utility model is the exclusion along the perimeter of the outer cells of the uneven pressure test displaced from the working cylindrical surfaces of the drums.

Utility Model Essence

The claimed technical result is achieved due to the fact that a number of main distinguishing features are introduced into the known device of the drum of the machine for the production of ravioli, including forming cells located at a predetermined distance from each other and facing the outer working cylindrical surface of the drum:

- cells are located on the drum in such a way that the minimum distance between the edges of adjacent cells lies in the range from 0.5 to 5 mm;

- at its edge near the cells, said surface has an edge whose width also lies within the same limits;

- the edge of the mentioned surface is made wavy - enveloping the outer cells of the drum near them (not exactly, but as if other cells are located on the outside);

- in front of the end surface of the drum, a step adjacent to said working surface is made, which has a cylindrical surface and a wavy surface corresponding to the shape of the edge of the said working surface;

- the height of the step is more than 0.5 mm.

The most effective use of the claimed drum can be obtained by implementing a number of particular distinguishing features:

- the minimum distance between the edges of adjacent cells, as well as the width of the edge, can lie in the range from 1 to 3 mm;

- the width of the edge can be equal to the minimum distance between the edges of adjacent cells ± 20% of the last;

- both edges of the said working surface can be made wavy, and at both ends of the drum may have a step;

- the depth of the step can be 3-7 mm;

- the wavy edge can be made like a wind wave, in which the radius of curvature on the crest is less than that on the sole (the orientation of the "wave" is the crest to a number of cells);

- the steps forming a wavy surface can make an angle equal to 90 ° ± 60 'with said working surface;

- said working surface can be made with a roughness not higher than Ra-1.25 (for example, Ra-0.63), and the wavy surface of the step is Ra-12.5 (for example, Ra-1.25).

g is the minimum distance between the edges of adjacent cells

h is the height of the step;

r is the radius of curvature of the wavy edge of the working cylindrical surface on the crest of the "wave";

t is the width of the edge (in general, as a rule, the edge should be of variable width).

Information about the feasibility of implementing a utility model

The claimed drum can be arranged as follows (the option of having wave-like surfaces and steps on both sides of the drum is considered).

Like the well-known drum, it includes forming cells 1 located at a predetermined distance from each other and facing the outer working cylindrical surface 2.

Unlike the known drum, the claimed cells are arranged in such a way that the minimum distance g between the edges of adjacent cells lies in the range from 0.5 to 5 mm and at its edge 5 near the cells (i.e. opposite the cells, and not between them) mentioned the surface has an edge 3, the width t of which also lies in the same range.

Those. the claimed drum interconnected minimum distance between cells and the width of the edge.

Moreover, the edge 4 of the mentioned surface itself is made wavy, enveloping the outer cells of the drum 11 in the region 8 - near them.

At the same time, in front of the end surface 10 of the drum, a step adjacent to said working surface is made with a height h of more than 0.5 mm (the best option is 3-6 mm).

The step has a cylindrical surface 7 and a wavy surface 9. The latter corresponds to the shape of the edge of the said working surface.

The minimum distance between the edges of adjacent cells, as well as the width of the edge, can range from 1 to 3 mm.

The width of the edge can be equal to the minimum distance between the edges of adjacent cells ± 20% of the latter - this is the best option.

The depth of the step can be 3-7 mm (the best option is 3-5 mm).

The wavy edge can be made like a wind wave, in which the radius of curvature r on the ridge is less than that (R) on the sole.

The steps forming a wavy surface can form an angle a equal to 90 ° ± 60 'with said working surface.

The mentioned working surface can be made with a roughness not higher than Ra-1.25 (for example, with a roughness Ra-0.63), and a wavy surface of the step - Ra-12.5 (for example, with a roughness Ra-1.25).

Drum operation

Drums are paired.

Each of them has its own test tape, between which the filling is fed into the zone of maximum approximation of the drums.

The filling, rushing into the cells, deforms the test strips - the final product is formed.

The working cylindrical surfaces of the drums crush the test tapes, forcing the dough into cells (in the region where the test tap molds were formed — not shown in FIG., Like the whole cell structure) —the individual items are separated.

The edges of the working surfaces cut off excess test tapes that fall into the space between the opposite steps at the ends of the drums.

The relationship of distinctive features with the claimed technical result

The exception of the non-uniformity of the test pressure displaced from the side of the working cylindrical surfaces of the drums around the perimeter of the outer cells is achieved due to the fact that the edge of the said working surface goes around the outer cell when all the other conditions specified in n.p.

Due to this, the same conditions for the formation of dumplings by internal and external cells are created.

This allows you to improve the appearance of products manufactured using the claimed drum - to provide the ability to produce identical products with a symmetrical configuration.

From this point of view, the uniformity of the molding conditions for the external and internal sides of the external cells is also important.
