The claimed invention relates to the food industry. In particular, it can be used in meat and meat processing, as well as in the fish and fish processing industry.

Distinctive features of the claimed invention can be implemented in high-performance equipment of culinary and confectionery industries, catering facilities (in units of canteens, restaurants, cafes).

The claimed invention is intended to provide high-performance manufacturing of a composite semi-finished food product that allows deep freezing. At the same time, in the presented materials, semi-finished products are mainly meant blanks from the shell (mainly consisting of dough) with a viscous consistency filling (for example, with minced meat), such as sausages, dumplings, ravioli, dumplings, pies, tartlets, etc.

State of the art

A device is known for the manufacture of semi-finished products (RF Patent for Utility Model No. 39448), including: a) means for forming a dough piece - rolling made with the possibility of forming at least two ribbons from the sheath material using at least two mechanisms containing at least two rotating each other towards each other rollers, installed relative to each other with a given gap, b) a means for supplying the filling with a wedge-shaped fragment oriented with the apex towards the forming zone of the semi-finished products - f cherepitel, configured to supply portions of filling between the tapes, c) filling unit - dispenser (fillings), configured to dose (portion) injection of filling into the meat feeder, for example, through (otherwise, through) outlet (e) channels (s) , d) the zone for forming semi-finished products, into which ribbons and portion-cells (molding) are fed, located in close proximity to each other and having a given shape of internal surfaces corresponding to the shape of the obtained semi-finished products, or include inserts of the appropriate shape, for example, cup-shaped screen elements, e) a stamping mechanism — drums (with many cells) installed with the possibility of rotation towards each other in opposite directions, and e) ejector means — a pusher located in the cells and made with the possibility of reciprocating movement relative to the cell. Additionally, such a device contains various kinematic circuits, closed at least one power unit.

This device is selected as a prototype of the claimed object.

The prototype dispenser is arranged as follows. It contains storage cavities - cylindrical channels - with pistons, exhaust channels by the number of storage cavities, a pushing system made in the form of a cam and designed to act on the pistons, as well as a filling distributor configured to overlap the storage cavities and mounted on one shaft with a pushing system. In this case, the filling distributor has through holes passing through the filling from the storage cavities to the exhaust channels, as well as a pocket facing the storage cavities, which communicates with the shaft, which, in turn, is hollow for supplying the filling under pressure.

The prototype cells are arranged as follows. Their inlets are predominantly oval. At the same time, at least a part of such holes is surrounded by an annular ledge — a perimeter sample, the working surface of which is designed to form the edge part of semi-finished products. In addition, the placement of a device for forming a relief pattern on the surface of semi-finished products is provided in the forming cells.

A close analogue does not require highly qualified staff and ensures the production of semi-finished products with an attractive appearance.

At the same time, however, the close analogue has some disadvantages:

- when forming tapes, overheating and drying of the shell material occurs,

- it is difficult to adjust the rolling to various shell materials,

- the tape at the exit of the rolling is torn,

- it is difficult to configure the output from rolling the tape of a given thickness,

- there is a capture of the shell material by a roller or one of the rollers,

- due to uncontrolled tightening of the tape due to the heterogeneity of the shell material and the related heterogeneity of the heterogeneity, there is a high probability of marriage in the work of the extreme cells of the drum, associated, in particular, with the opening of the shell of the semi-finished products,

- it is difficult to remove excess shell material,

- not guaranteed guaranteed tape covering the working area of the drums,

- assembly and commissioning is difficult,

- different rolling mechanisms are loaded,

- difficult sanitization, in particular, it is difficult to disassemble the device,

- excess pressure in the zone of formation of the tapes, which leads to excessive stresses in the tapes themselves, leading to their defective deformations,

- not guaranteed guaranteed clamping of tapes to the drums,

- there is a splashing of the tapes with the filling,

- the constancy of the mass of portions of the filling is not ensured due to the presence in the filling of a large amount of elastically deformable air,

- does not ensure the constancy of the parameters of the pulsed filling,

- high energy consumption is assumed,

- dispenser parts wear out quickly,

- the filling supply stability is not ensured,

- the identity of the portions is not ensured with the simultaneous and sequential supply of the filling over different cells,

- reliable bonding of the tapes is not provided, or an excessively wide edge part of the semi-finished product is obtained,

- semi-finished products are obtained with defective surface shape deviations,

- semi-finished products are poorly separated from the cells and the pusher,

- the stamping mechanism (drums) wears out quickly,

- drums are difficult to manufacture,

- large waste tape

- great deformation of the shell of semi-finished products (in particular, its uneven thickening), which is associated with extrusion of the shell material from the working zone into the cells of the zone of molding of semi-finished products,

- great effort molding of semi-finished products associated with a large area of the outer surface of the drums outside the cells,

- the occurrence of a test fold,

- it is difficult to remove a flock of shell material,

- high demands are placed on the manufacture of drums with specified dimensions and tolerances,

- it is difficult to remove the drums, for example, for their replacement or sanitation,

- for the sanitation of the drums, a complete disassembly of the device with a violation of kinematic connections is required,

- rigidity and stability of the structure is ensured by increasing material consumption,

- the appearance of a “test loop” in front of the molding zone is likely, which requires interrupting the manufacturing of semi-finished products and eliminating excess shell material,

- likely to break the tapes.

SUMMARY OF THE INVENTION

The purpose of the invention, reflecting the overall technical result achieved by the implementation of the claimed objects, is the creation of a high-performance device for the production of ravioli with optimal appearance in terms of attractiveness (without burrs, burrs, defective surface shape deviations) and the ratio of sizes and parameters.

In this aspect, the claimed invention also allows: to simplify the design of equipment for the production of semi-finished products, to reduce their material consumption and increase compactness, transportability, reduce the qualification requirements of staff.

Including the claimed technical result from the use of the presented inventions is:

The achievement of the claimed technical result is facilitated by the inclusion in a known device containing: a) a means for forming a dough piece - rolling, made with the possibility of forming at least two tapes from the sheath material using at least two mechanisms containing at least two rolls rotating towards each other, installed b relative to each other with a given gap, b) a filler supply means with a wedge-shaped fragment oriented with the apex toward the forming zone of the semi-finished products atov - a stuffer, made with the possibility of feeding portions of the filling between the tapes, c) filling unit - dispenser "(fillings), made with the possibility of dosed (batch) injection of the filling into the farmer, for example, by means of (otherwise

- through) the outlet (e) channels (s), d) the zone for forming semi-finished products, into which ribbons and portions-cells (molding) are fed, located in close proximity to each other and having a given shape of the internal surfaces corresponding to the shape of the obtained semi-finished products, or including inserts of the corresponding form, for example, cup-shaped screen elements, e) a stamping mechanism - drums (with many cells) installed with the possibility of rotation towards each other in opposite directions, and e) ejection medium property - pusher - located in the cells and made with the possibility of reciprocating movement relative to the cell, and additionally - various kinematic circuits closed on at least one power unit, while the dispenser may contain storage cavities - cylindrical channels - with pistons, exhaust channels along the number of storage cavities, the pushing system made in the form of a cam and designed to act on the pistons, as well as the filling distributor configured to overlap cavities and mounted (placed) on the same shaft with the pushing system, while the filling distributor can have through holes passing through the filling from the storage cavities to the exhaust channels, as well as a pocket facing the storage cavities communicating with the shaft, which in turn can be made hollow for supplying it with filling under pressure, and the cells may have oval-shaped inlet openings, while at least part of such openings may be surrounded by an annular ledge - sampling according to calorimeter, the working surface which is intended for molding the semi-finished edge portion, and in addition to forming the cells can be provided forming means for placing a pattern on the surface of the semifinished following main and partial distinctive features.

The rolling may contain a pressure roller, made with the possibility of its location relative to one of the mentioned rollers with a minimum clearance of about 0.1 mm, and relative to the other with a large gap lying in the range from 10 · s to 100 · s, while the gap between the rollers themselves can lie in the range from s to 10 s.

A roller with a minimum clearance with the roller can be made with a radius greater than the radius of the roller, while a roller with a large gap with the roller can be made with a radius approximately equal to the radius of the roller. So, for example, a roller that has a minimum clearance with the roller may have a radius of about 100 mm, and one that has a large clearance with the roller may have a radius of about 25% less than that indicated.

The rollers and the roller can be kinematically connected, for example, by means of a gear train, and this connection should ensure equality of the linear velocities of their working surfaces during rotation of the rollers and the roller.

The roller mount can be adapted to change or adjust a large gap.

So, for example, the roller mount can be made with the possibility of moving the latter around the circumference relative to the roller, which has a minimum clearance with the drum, while the approximate constancy of the minimum clearance should be ensured.

The fastening of at least one of the rollers can be made with the possibility of changing or adjusting the gap between the rollers.

So, for example, the fastening of one of the rollers can be made with the possibility of its rotation relative to an axis spaced more than 0.1 mm from the axis of its working surface.

For this, such a roller can be planted on a sleeve or axis with an eccentricity of the inner and outer surfaces greater than 0.1 mm.

Each of the mechanisms can have an independent drive, for example, a separate electric motor.

Additionally, the device may include a preliminary rolling unit of the shell material, configured to receive a blank of shell material with a thickness exceeding a large gap.

The rolling may also include plates for removing tapes from the rollers.

If the width of the working zone, defined as the eventual separation zone of semi-finished products, for which the smallest possible distance between the surfaces of the drums outside the cells, on the outer surface of the drums in the direction of their axes is 1 (more than 33, but less than 333 mm), then the width of the working tapes surfaces of the rollers can be from 1.03 · 1 to 1.33 · 2.

The rollers by means of pressure plates can be assembled into a block configured to move approximately along the working surfaces of the rollers.

Guides for the rotational movement of the rollers in the form of sliding or rolling bearings, on which the axis of the rollers can be mounted, can be made in the pressure plates, while at least on one side of the block the axis of the rollers can protrude beyond the pressure plate.

The plates can be fastened by means of at least one hairpin, the ends of which can be rigidly fixed relative to the axis of rotation of the drums, for example, in a frame.

On the supporting surfaces of the plate may contain an anti-friction coating or anti-friction linings.

So, for example, a teflon coating can be applied to the supporting surfaces of the plate, or a fluoroplastic gasket can be installed.

The block may also include a roller.

Each of the rolling mechanisms can have an independent drive.

The device may further include a preliminary rolling unit of the shell material, configured to receive blanks of shell material with a width less than the width of the working surfaces of the rollers.

The relative orientation of the drums and the meat feeder can be such that the minimum distance between their surfaces will be more than 0.5, but less than 2 mm, and this will ensure a guaranteed design clearance between the meat feeder and the belts in excess of 0.1 mm.

Moreover, the height of the wedge-shaped fragment can be more than 10, but less than 100 mm, and the angle at its apex can exceed 10 °.

The rib at the top of the wedge-shaped fragment can be blunted and have a radius of curvature greater than 0.1 mm.

The meat feeder may have at least one outlet of elongated shape with a ratio of the largest to smallest, exceeding 1, 2.

The number of minced meat outlet openings may be greater than or equal to the number of cells located on the drums in the same way relative to their outer surfaces forming them.

The minimum radius of curvature of the outlet of the meat feeder can exceed 1 mm, while its largest size does not exceed 30 mm.

The device may further include a dispenser containing outlet channels in an amount equal to the number of outlet openings, and the dispenser may be connected to the meat feeder with a flexible or rigid pipe with a number of independent directions equal to the number of outlet channels, and such directions can have approximately the same length not exceeding 1.5 m each with approximately the same minimum area of passage openings greater than 100 mm ² .

The filling dispenser pocket can be connected to the cavity of the dispenser shaft through an opening made in the dispenser body, while the volumes of the storage tanks can be approximately equal and at the same time not exceed 30'000 mm ³ each.

The distributor can be integral with the metering shaft or can be rigidly mounted on the shaft and at the same time additionally fixed relative to the latter by means of a key.

The length along the axis of each of the through holes of the distributor, determined by the thickness of the corresponding part of the latter, can be at least 10 but not more than 60 mm, and the diameter of such holes can be less than the diameter of the inlets of the storage tanks in which the pistons are located.

The drive of the metering shaft, leading the latter into rotational motion, can be made in the form of gear or chain gears, and the final drive element can be fixed relative to the shaft by means of a key.

The mounting device on the shaft of the functional elements of the dispenser, such as: the final drive element and / or the pushing system, and / or the distributor, can be configured to adjust the angular position of the pushing system relative to the distributor.

So, for example, the final drive element can be pressed against the cam by means of a nut, and at the same time, a certain mutual orientation of the cam and said element can be ensured by the protruding pin of the cam, which is included in one of the positioning holes of the said element.

Distribute may include two or more through holes, while the angular distance between the axes of adjacent through holes, measured from the axis of the shaft, should not exceed 180 °.

The cam of the pushing system of the dispenser may have at least two protruding parts.

Additionally, the device may include a stamping mechanism and a meat feeder, while the distributor can be kinematically connected with the drums in such a way that the moment when the through hole of the distributor closes the inlet opening of the storage tank coincides with the moment of closest approach of the lower edges of the drum cells closest to each other with the inner contour the surface of the cells forming, during the rotation of one of the drums, the molding zone of semi-finished products, with a symmetric tolerance, satisfying the range of this condition

$$\Delta \le \frac{\mathrm{eleven}}{3}\tau ,\left(\mathrm{one}\right)$$

where A is the symmetric tolerance for the coincidence of the moment when the through-hole of the distributor closes the inlet of the storage tank with the moment of the closest approach of the lower edges of the most closely located drum cells, τ is the propagation time of the pulse received in the pipeline from the piston.

With the specified kinematic connection, the dimensions of the through-hole of the distributor and the inlet of the storage tank can be made so that, following the indicated overlap of the holes, they completely overlap, respectively, with the object in which the tanks are made, and with the dispenser, when the upper edges of the respective cells come closer together after molding at least 1/3 of the semi-finished product .

The dispenser can be connected to a stuffing pump forcing the filling into the cavity of the dispenser shaft.

At the output of the stuffing pump, an adjustable gate valve can be installed, made with the possibility of controlling the filling pressure in the cavity.

The stuffing pump can use a variable frequency drive. For this, the stuffing pump may include an induction motor and a centrifugal impeller pump.

The stuffer can be installed at a distance from the zone of forming semi-finished products, not exceeding the maximum radius of the outer surface of the drums, while the dispenser can be made in the form of a stuffer feeder structural element located above the top of the wedge-shaped fragment, while the pipeline, for example, can be brought to the last, connected to a stuffing pump.

The dispenser may include a valve, which is a cylinder, and the latter may include at least one transverse hole of a given diameter.

The valve can be kinematically connected to the actuator, from which it receives rotation around its axis, while a gear or chain transmission with a finite element in the form of an asterisk can be used.

The cylinder may include at least one group of intersecting transverse holes of a given diameter, the minimum angles between the axes of the nearest of which are approximately the same.

The cylinder may be surrounded by a sleeve with a through hole.

The cylinder may include several groups of intersecting transverse holes of a given diameter spaced apart by more than 5 mm, the minimum angles between the axes of the nearest of which are the same.

The cylinder may include at least one pair of groups, the axis of the openings of which are parallel in pairs.

The cylinder may include at least one pair of groups, the axes of all holes of which are not parallel.

The cylinder may be surrounded by a sleeve with through holes in an amount equal to the number of groups of holes on the cylinder.

The dispenser may include a nozzle, which may include holes in the number of groups of holes of the cylinder and valve, made in the form of screws and / or bolts, and / or threaded rods, one for each hole of the nozzle.

Valves can be screwed onto fluoroplastic seals.

The dispenser may contain a chamber for uniform filling with the filling at a given pressure, the volume of which exceeds 10,000 mm ³ .

A damper can be located in the chamber, which is a piston or membrane spring-loaded with an elastic element or elastic medium, into which air under pressure is pumped through the inlet valve.

The valve can be kinematically connected with the drums in such a way that the moment of overlapping the bore of the sleeve or nozzle with the transverse bore of the cylinder will approximately coincide with the moment of closest approximation of the lower edges of the cells of the drums closest to each other - the cells forming the forming zone of the semi-finished products.

With the specified kinematic connection, the dimensions of the transverse bore of the cylinder and the holes of the sleeve or nozzle can be made so that they can completely overlap the holes after the indicated overlap with the sleeve or nozzle and cylinder, respectively, when the upper edges of the respective cells come together after molding at least 1/3 of the semi-finished product.

At the output of the stuffing pump or at the inlet of the stuffer, an adjustable gate valve can be installed, which is configured to control the filling pressure in the chamber.

The stuffing pump can use a variable frequency drive.

The stuffing pump may include an induction motor and a centrifugal impeller pump.

The depth of sampling along the perimeter of the cells can be more than a quarter, but less than twice the average thickness of the tapes, while the area of its working surface must satisfy the condition

$$k_{\mathrm{one}}\cdot \left(\frac{0}{10\text{mm}}-\mathrm{one}\right)<S<{\mathrm{<figure-callout\; id="2"\; label="k"\; filenames="00000034.png"\; state="\{\{state\}\}">k</figure-callout>}}_2\cdot \left(\frac{0}{10\text{mm}}-\mathrm{one}\right),\left(2\right)$$

where k ₁ = 20 mm ² ,

about - the average perimeter of the contour of the inlet openings of the cells,

k ₂ = 50 mm ² ,

and at the same time, the width of such a sample, as well as the curvature of the contour of the inlet of the cells are not constant, and on average the width of the sample is greater in that part of the cells where the contour of the inlet has a large curvature, while the maximum width of the sample exceeds the minimum and the maximum size, covering the contour of the inlet of the cells exceeds the minimum by at least 10, but also by no more than 100%.

At least part of the cells may include a translational motion guide or dovetail lock on its lateral surface, configured to install devices for forming a relief pattern on the surface of the semi-finished products.

The cell may contain a device for forming a relief pattern on the surface of the semi-finished products, including at least one plate-shaped fragment and one cylindrical fragment located in the cell, while the maximum transverse size of such a fragment (the last mentioned) is more than a quarter of the average thickness of the tapes, but less than half the minimum size covering the contour of the cell inlet.

The device for forming a relief pattern may contain both cells of the pair constituting the semi-finished product molding zone, and in this case, the corresponding plate-shaped fragments can be arranged so that they are crossed in the semi-finished product molding zone, and the corresponding cylindrical fragments can be located so that in the semi-finished product molding zone they are located opposite one another.

The mentioned fragments of a cylindrical shape can be made with such longitudinal dimensions or installed in a cell in such a way that, at maximum approximation, the minimum distance between them is commensurate with the average thickness of the tapes (no more than twice the width of the tapes).

At least in part of the cells, membranes made of plastically deformable material, such as rubber, can be installed behind their inlet openings, the edges of which can be rigidly fixed near the contour of the inlet of the cells.

So, for example, the membrane can be installed through a threaded ring into a threaded sleeve, which can be screwed into the drum body from the side of its outer surface.

Membranes can have a variable thickness.

Membranes can be made easily removable.

The cells can be located on the drum in such a way that with a maximum size covering the contour of the inlet, they will be oriented mainly in the direction of their movement.

The cells can be located on the drum in such a way that with a maximum size covering the contour of the inlet, they will be oriented mainly across the direction of their movement, while the ratio of the average maximum size covering the contour of the inlet of the cells, measured in the direction of their movement, to the average minimum size , covered by the contour of the inlet openings of the cells will be larger or the device may contain a pusher including rods to which can be attached screens in the cells, with a minimum gap between the surfaces of the latter and the inner side surfaces of the cells exceeding 0.1, but less than 0.5 mm, and through holes can be made at the bottom of the cells for free penetration of such rods into them, with an additional device may include a mechanism for moving the rods, configured to provide translational movement of the screens relative to the respective cells, and such a mechanism can be configured to provide itelno slow smooth moving screens toward the inlet cells and compared it with the fast motion of screens in the opposite direction - to the bottom.

Screens can be made of a material that has little adhesion to the shell material, such as fluoroplastic / or can have, at least on its working surface, an appropriate coating, such as Teflon.

The rod movement mechanism may include a cam comprising a step whose height is greater than or equal to the maximum stroke of the screens in the cells.

The cam can be freely mounted on the same axis with the drum, for example, on the console, while the specified orientation of the cam relative to the frame or the housing of the device can be provided by means of a counterweight.

At the bottom of the cell may contain holes made with the possibility of supplying air or process gas to their cavity under relative atmospheric pressure, while the device may further include means for pumping air or process gas, for example, into the inner cavity of the drum and the corresponding pipeline, as well as a unit intermittent supply of air or process gas into the cells, depending on the position of the latter relative to the zone of forming semi-finished products.

So, for example, an axis can be attached to the inner surface of the drum on racks, on which a curved plate can be planted, at one end of which a load can be located, and on the other - a gasket.

A variety of exhaust systems can also be provided in the cells. So, for example, an outlet can be made in the cell membrane. Outlets can be made in the body of the drum. In this case, they can be connected to the cell cavity by means of a groove and outlet openings in the threaded sleeve.

The inlet of at least part of the cells can be made semicircular in shape with a fragment whose contour has variable curvature and contains repeating protruding elements with an angular repetition period Y greater than 10 but less than 45 °, while the inner surface of such cells can also have repeating protruding elements whose angular repetition period is also approximately equal to y, while the height of the profile of the elements mentioned by the first and the height of the elements mentioned by the second are approximately the same and more than 2, but less than 5 mm .

The number of cells on the reels may satisfy the following condition:

where j is the number of cells that can simultaneously be crossed by the generatrix of the drum, such that the condition

$$j\le \left[\frac{D_{\text{b}}}{{\text{d}}_{\text{z}}}\right],\left(5\right)$$

D ₆ - the diameter of the outer surface of the drum, and

$$\mathrm{one\; hundred}\text{mm}\le {\text{D}}_{\text{b}}\le 400mm,\left(6\right)$$

The number of cells that can simultaneously be crossed by a drum generatrix can be more than 1, and the cells can be staggered on the surface of the drum.

Neighboring cells can be made mirrored.

The diameter of the outer surface of the drum may be more than 200, but less than 250 mm.

The drums can be installed so that their outer surfaces in the area of the working areas will be in contact.

From both edges, both drums may include selections.

The width of the working area can be equal to 100 ± 30 mm.

The inlets of all the cells of the drums around their perimeter can be surrounded by samples.

The cells can be located on the drums in such a way that the minimum distance between the contour of the inlets of adjacent cells will not exceed 2 mm.

Drums with precision manufacturing errors can be made identical.

The drums can have a kinematic connection locked on the power drive, built on the basis of gear and / or chain gears, providing an approximate equality of the linear speeds of their outer surfaces - working areas, and the mentioned linear speed can be at least 3, but not more than 30% linear speed of the working surfaces of the rollers.

The device can be made with the possibility of changing the ratio of linear velocities of the outer surfaces of the drums and the working surfaces of the rollers.

In it, a frequency-controlled electric drive can be used to rotate the drums, while a drive independent of the variable-speed drive can be used to rotate the rolling rollers.

To rotate the drums, the device may include an induction motor.

The drums can be installed in such a way that the minimum distance between them will not exceed a quarter of the average thickness of the tapes, while the device may additionally contain an alignment unit for the relative position of the drums, including at least one eccentric support of at least one of the drums or its axis.

The alignment unit may include eccentric bearings of each drum or their axes.

The support of at least one of the drums can be made with the possibility of its movement during adjustment along the axis.

So, at least one of the drums can be seated on a sleeve that mates with the body of the device or with its bed or with the axis of the drum by thread.

The drums can have a kinematic connection locked on the power drive, built on the basis of gear and / or chain gears, while at least one of the drums or at least one of the drum attachment devices can be rotated with at least one of them while the other is stationary.

So, for example, one of the drums can be rigidly attached to its axis by means of a sleeve and a pair of nuts.

At least one of the drums can be mounted on a cantilevered axis.

Both drums can be mounted on cantilevered axes, while from the side opposite the indicated fixing, the axes can be connected to each other by means of a retainer having a rigid structure.

Information confirming the possibility of implementing the invention

The inventive device for the production of semi-finished products of food from a shell with a filling may contain the following functional elements: a) means of forming a dough piece - rolling made with the possibility of forming at least two strips of shell material using at least two mechanisms containing at least two rotating each towards each other rollers installed relative to each other with a given gap, b) means of filling with a wedge-shaped fragment oriented vertices в towards the forming zone of semi-finished products - a meat feeder made with the possibility of feeding portions of filling between the tapes, c) a filling injection unit - a dispenser (fillings) made with the possibility of dosed (portioned) injection of the filling into the meat feeder, for example, by means of (otherwise, through) exhaust (e) channels (s), d) a zone for forming semi-finished products into which tapes and portions are fed - cells (molding) located in close proximity to each other and having a given shape of the internal surfaces corresponding to the shape of the resulting semi-finished products, or including inserts of the corresponding shape, for example, cup-shaped elements - screens, e) a stamping mechanism - drums (with many cells) installed with the possibility of rotation towards each other - in opposite directions, and e) ejector means - pusher, located in the cells and configured to reciprocate relative to the cell. Additionally, such a device contains various kinematic circuits, closed at least one power unit.

The dispenser can be arranged as follows. It may contain storage cavities - cylindrical channels - with pistons, exhaust channels by the number of storage cavities, a pushing system made in the form of a cam and designed to act on the pistons, as well as a filling distributor configured to overlap the storage cavities and mounted (placed) on one shaft with a pushing system. At the same time, the filling distributor can have through holes passing the filling from the storage cavities to the exhaust channels, as well as a pocket facing the storage cavities, communicating with the shaft, which in turn can be made hollow for supplying the filling under pressure.

Cells can be arranged as follows. Their inlets may be oval. At the same time, at least a part of such holes can be surrounded by an annular ledge — a perimeter sample, the working surface of which is designed to form the edge part of semi-finished products. In addition, placement of devices for forming a relief pattern on the surface of semi-finished products may be provided in the forming cells.

Moreover, these elements may have the following features.

Additionally rolling (figure 1) contains a pressure roller 5, made with the possibility of its location relative to one of the mentioned rollers, for example, 8 with a minimum clearance of about 0.1 mm, and relative to the other, for example, 1 with a large clearance Z lying in the range from 10 · s to 100 · s, while the gap between the rollers themselves t lies in the range from s to 10 · s.

A roller with a minimum clearance with the roller can be made with a radius R greater than the radius of the roller, while a roller with a large gap with the roller can be made with a radius r approximately equal to the radius of the roller. So, for example, a roller that has a minimum clearance with the roller may have a radius of about 100 mm, and one that has a large clearance with the roller may have a radius about 25% smaller than that indicated (i.e., about 75 mm).

The rollers and the roller can be kinematically connected, for example, by means of a gear transmission, and this connection should ensure that the linear velocities of their working surfaces 2, 3 and 7 are equal when the rollers and the roller rotate along arrows A, B, C.

The roller mount can be adapted to change or adjust a large gap.

So, for example, the roller can be mounted with the possibility of moving the latter around a circle with a radius R _z relative to the roller, which has a minimum clearance with the roller, while ensuring an approximate constancy of the minimum clearance.

The fastening of at least one of the rollers can be made with the possibility of changing or adjusting the gap between the rollers.

So, for example, the fastening of one of the rollers can be made with the possibility of its rotation relative to the axis O ₂ , spaced more than 0.1 mm from the axis of its working surface O ₁ .

For this, such a roller can be fitted onto a sleeve or an axis with an eccentricity of the inner and outer surfaces e _t > 0.1 mm.

Each of the mechanisms can have an independent drive, for example, a separate electric motor.

Additionally, the device may include a preliminary rolling unit of the shell material, configured to receive a blank of shell material with a thickness exceeding a large gap.

The rolling may also include plates 4 and 6 for removing tapes from the rollers.

If the width of the working zone 11 (figure 2), defined as the eventual zone of separation of semi-finished products, for which the smallest possible distance between the surfaces of the drums outside the cells, on the outer surface of the drums in the direction of their axes is l (more than 33, but less than 333 mm), then the width of the working surfaces, determined by the exit region of the tapes 9, of the rollers can be from 1.03 · l to 1.33 · l.

The rollers (Fig. 3) by means of pressure plates 15 can be assembled into a block configured to move approximately along the working surfaces of the rollers in the direction of arrow D.

Guides for the rotational movement of the rollers in the form of sliding or rolling bearings, on which the axis of the rollers can be mounted, can be made in the pressure plates, while at least one side of the roller axis axis can protrude beyond the pressure plate (not shown in the figure).

The plates can be fastened by at least one hairpin, the ends of which, for example, 14 are rigidly fixed relative to the axis of rotation of the drums, for example, in the frame. The degree of tightening of the nuts 16 can be determined by sampling the gap between the plates and rollers.

On the supporting surfaces of the plate may contain an anti-friction coating or anti-friction linings.

So, for example, a teflon coating 13 can be applied to the supporting surfaces of the plate, or a fluoroplastic gasket 17 can be installed.

The block may also include a roller.

Each of the rolling mechanisms can have an independent drive.

The device may further include a preliminary rolling unit of the shell material, configured to receive blanks of shell material with a width less than the width of the working surfaces of the rollers.

The relative orientation of the drums and the meat feeder (figure 4) can be such that the minimum distance between their surfaces F _b more than 0.5, but less than 2 mm, and this ensures a guaranteed design clearance f between the meat feeder and the belts in excess of 0.1 mm

Moreover, the height h of the wedge-shaped fragment 21 may be greater than 10, but less than 100 mm, and the angle a at its apex may exceed 10 °.

The rib 26 at the apex of the wedge-shaped fragment can be blunted and have a radius of curvature greater than 0.1 mm.

The meat feeder may have at least one outlet 27 (FIG. 5) of an elongated shape with a ratio of the largest size p to the smallest q exceeding 1, 2.

The number of minced meat outlet openings may be greater than or equal to the number of cells located on the drums in the same way relative to their outer surfaces forming them.

The minimum radius of curvature p of the mince-feeder outlet may exceed 1 mm, while its largest size p does not exceed 30 mm.

The device may additionally include a dispenser 18, made with the possibility of metered injection of the filling into the meat feeder and containing outlet channels 31 (Fig.6) in an amount equal to the number of outlet openings, while the dispenser can be connected to the meat feeder with a flexible or rigid pipe with a number of independent directions ( pos. 20 one of the directions is indicated), equal to the number of exhaust channels, and such directions can have approximately equal length L not exceeding 1.5 m each with approximately the same minimum area di through holes 19, greater than 100 mm ² .

The pocket 38 (Fig. 6) of the dispenser of the filling 33 can be connected to the cavity 39 of the dispenser shaft via an opening 35 made in the dispenser body, while the volumes of the storage tanks can be approximately equal and do not exceed 30,000 mm ³ each.

The distributor can be integral with the metering shaft or can be rigidly mounted on the shaft and at the same time additionally fixed relative to the latter by means of a key.

The length along the axis of each of the through holes 30 of the distributor, determined by the thickness of the corresponding part of the latter, can be at least 10 but not more than 60 mm, and the diameter of such holes can be less than the diameter of the inlet openings 37 of the storage tanks in which the pistons 29 are placed.

The drive of the metering shaft, leading the latter into rotational motion, can be made in the form of gear or chain gears, and the final drive element can be fixed relative to the shaft by means of a key.

The mounting device on the shaft of the functional elements of the dispenser, such as: the final drive element and / or the pushing system, and / or the distributor, can be configured to adjust the angular position of the pushing system relative to the distributor.

So, for example, the final drive element can be pressed against the cam by means of a nut 34, and a certain mutual orientation of the cam and said element can be ensured by the protruding pin 32 of the cam, which is included in one of the positioning holes of the said element, such as 36.

Distribute may include two or more through holes, while the angular distance between the axes of adjacent through holes, measured from the axis of the shaft, should not exceed 180 °.

The cam of the pushing system of the dispenser may have at least two protruding parts 28.

Additionally, the device may include a stamping mechanism and a meat feeder, while the distributor can be kinematically connected with the drums in such a way that the moment of overlapping with the through hole of the distributor of the inlet opening of the storage tank coincides with the moment of closest approach of the lower edges 25 closest to each other (Fig. 4) the cells of the drums with the contour of the inner surface of 24 - cells, forming when rotating one of the drums in the direction of arrow E, and the other in the opposite direction, the zone of forms semifinished products 23, with a symmetric tolerance satisfying the condition

$$\Delta \le \frac{\mathrm{eleven}}{3}\tau ,\left(\mathrm{one}\right)$$

where Δ is the symmetric tolerance for the coincidence of the moment when the through-hole of the distributor closes the inlet of the storage tank with the moment of the closest approximation of the lower edges of the drum cells closest to each other, τ is the propagation time of the pulse received by it from the piston in the pipeline.

With the specified kinematic connection, the dimensions of the through-hole of the distributor and the inlet of the storage tank can be made so that, following the indicated overlap of the holes, they completely overlap, respectively, with the object in which the tanks are made, and with the dispenser, when the upper edges of the respective cells come closer together after molding at least 1/3 of the semi-finished product .

The dispenser can be connected to a stuffing pump forcing the filling into the cavity of the dispenser shaft.

At the output of the stuffing pump, an adjustable gate valve can be installed, made with the possibility of controlling the filling pressure in the cavity.

The stuffing pump can use a variable frequency drive. For this, the stuffing pump may include an induction motor and a centrifugal impeller pump.

The stuffer can be installed at a distance from the zone of forming semi-finished products, not exceeding the maximum radius of the outer surface of the drums, while the dispenser can be made in the form of a stuffer feeder structural element 22 located above the top of the wedge-shaped fragment, when, as with the latter, for example, through hole 40 (Fig. 7) a pipeline connected to a stuffing pump can be supplied.

The dispenser includes a valve 50, which is a cylinder, and the latter may include at least one transverse hole of a given diameter.

The valve can be kinematically connected to the actuator, from which it receives rotation around its axis, while a gear or chain transmission with a finite element in the form of an asterisk 49 can be used.

The cylinder may include at least one group of 51 intersecting transverse holes of a given diameter, the minimum angles between the axes of the nearest of which are approximately the same.

The cylinder may be surrounded by a sleeve with a through hole 53.

The dispenser may include a nozzle and a valve made in the form of a screw or bolt, or threaded rod 43.

The cylinder includes several groups spaced more than 5 mm apart, intersecting the transverse holes of a given diameter, the minimum angles between the axes of the nearest of which are the same.

The cylinder includes at least one pair of groups, the axis of the openings of which are parallel in pairs.

The cylinder may include at least one pair of groups, for example, 51 and 54, the axes of all holes of which are not parallel.

The cylinder may be surrounded by a sleeve 52 with through holes in an amount equal to the number of groups of holes on the cylinder.

The dispenser may include a nozzle 44, which may include holes 45 in the number of groups of cylinder and valve holes, made in the form of screws and / or bolts and / or threaded rods, one for each hole of the nozzle.

Valves can be screwed onto PTFE seals 42.

The dispenser may contain a chamber 41 for uniformly filling with a filling at a given pressure, the volume of which exceeds 10'000 mm ³ .

A damper may be located in the chamber, which is a piston or membrane 46 spring-loaded with an elastic element or elastic medium, into which space 47 is pumped under pressure through the inlet valve 48.

The valve can be kinematically connected with the drums in such a way that the moment of overlapping the bore of the sleeve or nozzle with the transverse bore of the cylinder approximately coincides with the moment of maximum closeness of the lower edges of the drum cells, the cells that form the semi-finished product forming zone, closest to each other.

With the specified kinematic connection, the dimensions of the transverse bore of the cylinder and the holes of the sleeve or nozzle can be made so that they can completely overlap the holes after the indicated overlap with the sleeve or nozzle and cylinder, respectively, when the upper edges of the respective cells come together after molding at least 1/3 of the semi-finished product.

At the output of the stuffing pump or at the inlet of the stuffer, an adjustable gate valve can be installed, which is configured to control the filling pressure in the chamber.

The stuffing pump can use a variable frequency drive.

The stuffing pump may include an induction motor and a centrifugal impeller pump.

The depth of sampling along the perimeter of the cells can be more than a quarter, but less than twice the average thickness of the tapes, while the area of its working surface 56 (Fig. 8) satisfies the condition

$$k_{\mathrm{one}}\cdot \left(\frac{0}{10\text{mm}}-\mathrm{one}\right)<S<{\mathrm{<figure-callout\; id="2"\; label="k"\; filenames="00000034.png"\; state="\{\{state\}\}">k</figure-callout>}}_2\cdot \left(\frac{0}{10\text{mm}}-\mathrm{one}\right),\left(2\right)$$

where k ₁ = 20 mm ² ,

about - the average perimeter of the contour of 55 inlet openings of the cells,

k = ₂ to 50 mm ^2,

and the width of such a sample, as well as the curvature of the contour of the inlet of the cells, are not constant, and on average the width of the sample is greater in that part of the cells where the contour of the inlet has a large curvature, while the maximum width H _{in the} sample exceeds the minimum h _in , and the maximum size D _i covering the contour of the inlet of the cells exceeds the minimum d _{i by} at least 10, but also by no more than 100%.

At least part of the cells may include on its lateral surface 57 a translational motion guide or dovetail lock 59 configured to install devices for forming a relief pattern on the surface of the semi-finished products.

The cell may contain a device for forming a relief pattern on the surface of the semi-finished products, including at least one fragment of the plate shape 60 and one fragment of the cylindrical shape 61 located in the cell, while the maximum transverse dimension D _n (Fig. 9) of such a fragment (the last mentioned) is larger a quarter of the average thickness of the tapes, but less than half of the minimum size, covering the contour of the cell inlet.

The device for forming a relief pattern may contain both cells of the pair constituting the semi-finished product molding zone, and in this case, the corresponding plate-shaped fragments can be arranged so that they are crossed in the semi-finished product molding zone, and the corresponding cylindrical fragments can be located so that in the semi-finished product molding zone they are located opposite one another.

The mentioned fragments of a cylindrical shape can be made with such longitudinal dimensions h _n or so installed in the cell that with a maximum approximation, the minimum distance h _l between them is commensurate with the average thickness of the tapes (not more than twice the width of the tapes).

At least in part of the cells beyond their inlet openings, membranes 68 (Fig. 12) of plastically deformable material, such as rubber, the edges of which can be rigidly fixed near the contour of the inlet of the cells can be installed.

So, for example, the membrane by means of a threaded ring 66 can be installed in the threaded sleeve 64, which can be screwed into the body of the drum 62 from the side of its outer surface.

Membranes can have a variable thickness. Membranes can be made easily removable. The cells can be located on the drum in such a way that with a maximum size covering the contour of the inlet, they will be oriented mainly in the direction of their movement (Fig. 8).

The cells can be located on the drum in such a way that the maximum size covering the contour of the inlet, they will be oriented mainly across the direction of their movement, while the ratio of the averaged maximum size T _I (figure 10), covering the contour of the inlet of the cells, measured in the direction their movement, to the average minimum size t _i covered by the contour of the inlet openings of the cells is greater than or equal to 1.1.

The device may include a pusher including rods 82 (Fig.13), to which screens 83 located in the cells can be attached, with a minimum clearance between the surfaces of the latter and the inner side surfaces of the cells exceeding 0.1, but less than 0.5 mm, and through holes 58 (Fig. 8) for free penetration of such rods into them can be made at the bottom of the cells, while the device can further include a rod movement mechanism configured to provide translational movement of the screens relative tionary respective cells, and such a mechanism can be configured to provide a relatively slow smooth moving screens toward the inlet cells and compared quick screens movement in the opposite direction - to the bottom.

Screens can be made of a material that has little adhesion to the sheath material, such as fluoroplastic, or can have, at least on its working surface, an appropriate coating, such as Teflon.

The rod movement mechanism may include a cam 80 (FIG. 13) containing a step whose height he is greater than or equal to the maximum stroke of the screens in the cells.

The cam can be freely mounted on the same axis with the drum, for example, on the console 79, while the specified orientation of the cam relative to the frame or the housing of the device can be provided by means of a counterweight 81.

At the bottom 74 (Fig. 12) of the cell, openings 71 can be arranged, which can supply air or process gas to their cavity 72 under atmospheric pressure, while the device can further include means for injecting air or process gas, for example, into the internal the cavity of the drum 78 and the corresponding pipeline, as well as the intermittent supply of air or process gas into the cell, depending on the position of the latter relative to the molding zone of the semi-finished products.

So, for example, an axis can be attached to the inner surface of the drum 73 on the uprights 67, on which a curved plate 65 can be fitted, at one end of which a load 63 can be located, and on the other - a gasket 69. When the drum rotates in the direction of arrow E, the load gravity will move toward the inner surface of the drum, and the inlet of the cell will be open - the gas will enter the cavity of the cell and, for example, will contribute to the straightening of the membrane, acting as a pusher, contributing to the separation of semi-finished products from the cell ki. The moments of opening and closing the inlet of the cell are determined by the position of the center of gravity of the load s _g relative to the axis on the uprights - the smaller s _g , the sooner after the cells exit the molding zone the inlet will open.

A variety of exhaust systems can also be provided in the cells. Thus, for example, an outlet 70 may be formed in the cell membrane. Outlets 75 may also be formed in the body of the drum. In this case, they can be connected to the cell cavity by means of a groove 77 and outlet holes in the threaded sleeve 76.

The inlet of at least part of the cells can be semicircular in shape (Fig. 11) with a fragment whose contour has variable curvature and contains repeating protruding elements with an angular repetition period of greater than 10 but less than 45 °, while the inner surface of such cells may also have repeating protruding elements, the angular period of which is also approximately equal to y, while the height H _{e of the} profile of the elements mentioned by the first and the height h _{e of the} elements mentioned by the second are approximately the same and greater than 2, but less than 5 mm.

The number of cells on the reels may satisfy the following condition:

$$2\cdot j\cdot \frac{D_{\text{b}}}{{\text{D}}_{\text{I am}}}\le n\le 2^2\cdot j\cdot \frac{D_{\text{b}}}{{\text{d}}_{\text{I am}}},\left(\mathrm{four}\right)$$

where j is the number of cells that can simultaneously be crossed by the generatrix of the drum, such that the condition

$$j\le \left[\frac{D_{\text{b}}}{{\text{d}}_{\text{z}}}\right],\left(5\right)$$

D ₆ - the diameter of the outer surface of the drum, and

$$\mathrm{one\; hundred}\text{mm}\le {\text{<figure-callout id="6" label="D" filenames="00000034.png" state="{{state}}">D</figure-callout>}}_{\text{6}}\le 400\text{mm}\text{,}\left(\text{6}\right)$$

D _i - the maximum size covering the contour of the cell inlet,

d _i - the minimum size covering the contour of the inlet of the cell,

while the drums can be installed so that the minimum distance between them will not exceed half the average thickness of the tapes, and at least one edge of at least one of them can have a sample of 10 (figure 2) depth, which can be defined as half the difference the diameter of the outer surface of the drum and the diameter d _{b of the} sample exceeding half the average thickness of the tapes, and a width of 5 to 25% of the width of the working area, defined as the eventual separation zone of semi-finished products, for which the smallest possible the distance between the surfaces of the drums outside the cells, on the outer surface of the drums in the direction of their axes, while such a width is from 30 to 300 mm.

The number of cells that can simultaneously be crossed by a drum generatrix can be more than 1, and the cells can be staggered on the surface of the drum.

At the same time, there can be two or more cells located relative to the generatrix of the outer surface of the drum in the same way (in Fig. 2, item 12, the lower edges of such cells approaching the forming zone of semi-finished products are indicated).

Neighboring cells can be made mirrored (11).

The diameter of the outer surface of the drum may be more than 200, but less than 250 mm.

The drums can be installed so that their outer surfaces in the area of the working areas will be in contact.

From both edges, both drums may include selections.

The width of the working area can be equal to 100 ± 30 mm. The inlets of all the cells of the drums around their perimeter can be surrounded by samples.

The cells can be located on the drums in such a way that the minimum distance between the contour of the inlets of adjacent cells will not exceed 2 mm.

Drums with precision manufacturing errors can be made identical.

The drums can have a kinematic connection locked on the power drive, built on the basis of gear and / or chain gears, providing an approximate equality of the linear speeds of their outer surfaces - working areas, and the mentioned linear speed can be at least 3, but not more than 30% linear speed of the working surfaces of the rollers.

The device can be made with the possibility of changing the ratio of linear velocities of the outer surfaces of the drums and the working surfaces of the rollers.

In it, a frequency-controlled electric drive can be used to rotate the drums, while a drive independent of the variable-speed drive can be used to rotate the rolling rollers.

To rotate the drums, the device may include an induction motor.

The drums can be installed in such a way that the minimum distance between them will not exceed a quarter of the average thickness of the tapes, while the device may further comprise an alignment unit for the drums, including at least one eccentric support 88 (Fig. 14) of at least one of the drums or its axis.

The alignment unit may include eccentric bearings of each drum or their axes.

The support of at least one of the drums can be made with the possibility of its movement during adjustment along the axis.

So, at least one of the drums can be seated on the sleeve 84, mating with the housing of the device or with its bed 89 or with the axis 86 of the drum by thread.

The drums can have a kinematic connection locked on the power drive, built on the basis of gear and / or chain gears, while at least one of the drums or at least one of the drum attachment devices can be rotated with at least one of them while the other is stationary.

So, for example, one of the drums can be rigidly attached to its axis by means of a sleeve and a pair of nuts 87.

At least one of the drums can be mounted on a cantilevered axis.

Both drums can be mounted on cantilevered axes, while from the side opposite the indicated fixing, the axes can be connected to each other by means of a retainer 85 having a rigid structure.

The inventive device operates as follows.

Between the rollers rotating in opposite directions and the upper roller, a dough pre-matured for at least 30 s is supplied in the form of a wide but low parallelepiped, which is captured by them and, falling on the lower roller, is sent to the tape forming zone.

The use of the described workpiece eliminates excess pressure in the zone of formation of the tapes, as well as excessive stresses in the tapes themselves and defective deformations.

The declared geometry of rolling provides an exception during the formation of tapes of overheating and drying of the shell material, as well as the capture of shell material by a roller or one of the rollers.

If necessary, the mutual positions of the rollers and rollers are changed, providing the adjustment of the rolling for various shell materials, in particular, with the aim of eliminating breaks in the tapes at the exit of the rolling or adjusting the rolling for the shaping of tapes of a given thickness.

In order to simplify the assembly of the device, each of its rolling mechanisms includes an independent electric drive, which also, on the one hand, provides the same load on the rolling mechanisms, and, on the other hand, makes it possible to obtain uniform tape thicknesses.

The tapes received in the rolling are fed to two drums. In this case, the width of the tapes at the exit of the rolling significantly exceeds the width of the working zone of the drums, which makes it possible to compensate for the uncontrolled tightening of the tapes arising due to the heterogeneity of the shell material and eliminate the marriage in the work of the extreme cells of the drum, which is expressed, in particular, in the opening of the shell of semi-finished products.

The indicated geometric parameters of the rollers and drums also provide a significant simplification of the removal of excess shell material from the zone of forming semi-finished products.

In this case, if necessary, the rolling blocks are moved relative to the drums, ensuring guaranteed coverage of the working areas with tapes.

The tapes captured by the rotating drums move to the forming zone of the semi-finished products and by means of a wedge-shaped fragment of the meat feeder are guaranteed to be pressed to the working area of the drums - the knife shape of the meat feeder serves as a guide for the intumescent dough.

Next, between the tapes from the outlet openings of the meat-feeder, portions of the filling are fed. The indicated geometrical parameters of the mince feeder outlet completely eliminate the splashing of the tapes with the filling.

The operation of the stuffer is provided by a dispenser into which the filling comes from a stuffing pump, preferably having an adjustable drive or adjustable gate valves. Adjusting the filling pressure is extremely necessary, in particular, to maintain a constant ratio of the mass of the shell material to the mass of the filling in the semi-finished products, regardless of the aging time of the filling. The fact is that the latter is a mixture of, for example, meat with air (in dumplings), as a result of which, when the filling pressure changes, its density changes, which means the mass of the filling in semi-finished products.

In the first described embodiment, the operation of the dispenser is based on the alternate loading and unloading of storage tanks by means of a filling distributor and a pushing system with pistons, respectively.

In the second embodiment, the operation of the dispenser is based on the operation of the valve, which alternately blocks the entry of the filling into the output openings of the meat feeder.

The design features of the dispensers presented ensure a constant mass of servings of the filling despite the presence of a large amount of elastically deformable air in it, stability of the filing supply and the constancy of the parameters of its pulsed supply, low power consumption, a long time between the dispensers for failure, the identity of the batches with simultaneous and sequential filling of the filling over different cells.

Portions of the filling slightly deform the ribbons in the area of the cell inlet openings, which, closing when the drums rotate towards each other, provide the final molding and separation of the semi-finished products.

The described coordination of the supply of portions of the filling with the entrance of the cells to the zone of formation of semi-finished products eliminates the formation in the shell of the last chips, as well as micro- and macrocracks.

The design features of the cells described in the application materials, including their location on the drum and the use of membranes, provide improved gluing of sheets, reliable gluing of tapes with a small edge part of the semi-finished product, uniform thickness of the shell, eliminate defective deviations in the shape of their surfaces, adhesion of the shell to parts devices.

The use of devices for forming a relief pattern on the surface of semi-finished products provides the opportunity to give semi-finished products the shape of hand-made products.

When the cells with finished semi-finished products begin to move away from the molding zone, an ejection system based on the operation of the cam mechanism or compressed air is included in the work.

The presented variants of such a system provide a guaranteed separation of semi-finished products from cells and screens, in particular, due to the inertial effect.

The parameters of the drums were chosen by the authors based on the requirements for low wear of the stamping mechanism, ease of manufacture, minimization of tape waste, minimization of the deformation of the shell of semi-finished products (in particular, its uneven thickening) associated with extrusion of the material of the shell from the working zone into the cells of the zone of forming semi-finished products.

The presented design of the drums provide a relatively low force forming the semi-finished products, in particular, in connection with the small area of the outer surface of the drums outside the cells.

The indicated ratio of the linear velocities of the outer surfaces of the drums and the working surfaces of the rollers ensures the exclusion of the test folds, as well as the breaking of the tapes.

Samples along the edges of the drums make it easy to remove the accumulating shell of shell material.

Semi-finished products separated from the cells enter a special container and are sent to the freezer.

When setting up the device, special attention is paid to aligning the drums. Preferred is their mutual arrangement in which they are in contact with their generators or between those there is a gap of the order of 0.02 mm when they are parallel. For this, an adjustment unit is used, which allows not to place high demands on the manufacture of drums and other parts and components of the device.

The angle between the generators of the drums is corrected using at least two eccentric bearings.

In another design, the parallelization of the forming drums is ensured constructively. In this case, eccentric supports are used to eliminate the gap between the generators in the zone of eventual contact.

The eccentric supports also allow you to part the drums to adjust their mutual rotation, which is necessary for the exact combination of the cells of the molding zone, as well as for disassembling the device and sanitation.

Using the console mounting of the drums greatly simplifies the sanitation of the drums, without requiring complete disassembly of the device and violation of kinematic relationships. The use of the described latch provides rigidity and stability of the structure with low material consumption.

The presented design features of the claimed device, in particular the mentioned adjustments, including the drives, provide for simple assembly-disassembly, in particular during sanitation and commissioning of the machine.

In general, the inventions make it possible to create high-performance devices for the production of ravioli with an optimal appearance from the point of view of attractiveness (without burrs, burrs, defective surface shape deviations) and the ratio of sizes and parameters. The total time spent in operation of the inventive device per unit of production, taking into account marriage, is more than two times lower in comparison with the prototype.

Using the distinguishing features of any of the independent claims allows us to simplify the design of equipment for the production of semi-finished products, reduce their material consumption and increase compactness, transportability, and reduce the requirements for the qualification of staff. The cost of relevant work in the implementation of these characteristics is almost two times lower compared to the prototype.

The service life of the main components of the claimed device is approximately three times higher in comparison with the prototype.
