Description

The utility model proposed for patenting relates to the production of food products from dough with filling, specifically dumplings.

A device for the manufacture of dumplings from a dough tube with minced meat (see patent RU No. 2042328, 1992). There is also known a line for the production of ravioli, where a blank is cut from a dough tape, into which the filling is then introduced using a minced syringe (see patent RU No. 2134969, 1999). The disadvantages of these analogues include their complexity and bulkiness.

The closest, in our opinion, to the proposed utility model is a dumpling machine according to patent RU No. 50759, 2005 - a prototype. In this machine, dumplings are stamped using a pair of paired drums with cells. Dough tapes are passed between the drums, which are rolled out using rollers. The dough on the rollers slides on top of the tray. The filling for dumplings is served in the joint between the dough ribbons (hereinafter referred to as the ribbons) with the help of a stuffing pump, which pumps the stuffing through the feed tubes at a constant speed.

The disadvantages of this device include the fact that when the stuffing pump is operated at a constant speed, the dough shells are filled with minced meat unevenly, as a result of which the dumplings have a dented appearance. If you simply increase the feed rate of the stuffing, then it begins to accumulate at the junction of the tapes with a slide, which then falls off. This leads to loss of stuffing and contamination of the machine. This effect is explained by the fact that the cells during the rotation of the drums move relative to the supply tubes with a variable speed: first with deceleration, then with acceleration (according to the sine law). It follows that at a constant speed of the stuffing pump, the supply of meat is not synchronized with the movement of the cells. At the beginning of the formation of dumplings, when the speed of the cells is high, the filling is not enough,

and at the end, when the speed is zero, but the cells are already docked, the stuffing goes past the shells, forming a hill. In addition, as practice shows, when a stuffing pump is operated at a constant speed, the filling in the feed tubes is often pressed into traffic jams. To clean the tubes, it is necessary to stop the machine, which reduces productivity.

Another disadvantage of the prototype is the imperfection of the dough feeder, made in the form of an open tray. If the capacity of the tray is small, you often have to add dough. If there is a gap between the additive and the rest of the dough on the tray, the feed of the dough on the rollers and the break of the dough belts may fail. In this case, the machine has to be stopped, since the filling begins to flow into the cells without dough. If the tray area is increased, then when a certain volume is reached, the dough mass begins to slide past the rollers, which leads to loss of dough.

The technical task is to improve the quality of dumplings and performance by combining a pulsed feed of minced meat with a continuous supply of dough.

The technical result is achieved by the fact that in a device for the production of ravioli, including tubes for supplying minced meat, a dough feeder communicated with rollers for rolling out the dough belts and feeding them to stamping drums with forming cells arranged in staggered cylindrical surfaces, tubes for supplying minced meat made of elastic material, while the device is equipped with a forcemeat flow chopper, made with the possibility of periodic, partial or complete, crushing tubes.

The device is characterized in that the mincemeat flow interrupter contains electromagnets connected to a pulse voltage source, whose anchors have pins that are capable of interacting with minced meat supply tubes. The device is also characterized in that the pulse voltage source is configured to separately supply voltage pulses in sequence, synchronized

with the sequence of interfacing cells on stamping drums. The device is characterized in that the pins are made with a bevel facing the minced meat.

The device is characterized in that the test feeder is made in the form of a hopper equipped with a funnel for dispensing the test, inside of which feed and sealing rollers for the test connected with the drive are installed. The device is also characterized in that the feed rollers have fins with a rib height of 3 to 8 mm.

The proposed utility model is illustrated by drawings. Figure 1 schematically shows a section of the device in a vertical plane; figure 2 - chopper stuffing; figure 3 is a section aa in figure 2 (rotated).

In an example of a specific embodiment, the device comprises a test feeder 1, including a hopper 2 with a mechanism including feed 3 and sealing rollers 4, connected by gears 5. On the rollers 3 there are fins in the form of blades 6. The height of the blades can be from 3 to 8 mm, depending on type of dough (soft, hard, etc.). At the bottom of the hopper there is a window with a funnel 7 of rectangular cross section. The funnel is mounted above the rollers 8, 9 for rolling the dough strips 10, 11. Under the rollers, stamping drums 12, 13 are installed. On the cylindrical surfaces of the drums there are two rows of forming cells that are staggered (not shown). The adjacent rows of cells, for a sample with 10 cells in a row, are offset by an angle of 18 °.

Tubes for supplying minced meat 14 connected to a stuffing pump (not shown) are installed in the interface plane of drums 12, 13. The number of tubes 14 is equal to the number of rows of cells on the drum. Tubes made of an elastic material (for example, polyethylene) are laid through a breaker 15. The breaker contains electromagnets 16, 17 with anchors 18, 19. The anchors have shanks in the form of elastic plates 20, the ends of which are attached to the electromagnets using struts 21, and pins 22, on which

bevels 23 are made, facing the side of minced meat delivery from the tubes 14 (i.e., down).

The windings of the electromagnets 16, 17 are independently connected to the source of the pulse voltage IIN (not shown). The operation of the INN is synchronized with the rotation speed of the stamping drums 12, 13 so that the supply voltage pulses are supplied to the electromagnets 16, 17 separately in turn with a time shift corresponding to the shift between the moments of passage of cells of adjacent rows through the drum coupling line. Positions 24, 25 and 26 indicate the finished dumplings, conveyor and container for dumplings, respectively.

With the device for the production of ravioli work in the following order. Pre-kneaded dough is laid in the required quantity in the hopper 2 and turn on the device drive (not shown). The dough falls between the rotating rollers 3, 4, which compact it to the desired consistency. Then the rollers 4 direct the dough into the funnel 7, from where it comes out in the form of a continuous plate of rectangular cross section. The dough plate is fed to the rollers 8, 9, which are rolled onto strips 10, 11. For stamping dumplings, the ends of the strips 10, 11 are inserted between the stamping drums 12, 13, after which the stuffing pump and the power supply of the IIN are turned on.

When the rolls rotate, the rolled tapes 10, 11 are continuously fed to the mating line of the drums 12, 13, which can be conditionally divided into the first and second zones (for the first and second rows of stamping cells). The automation equipment provides that at the moment of coupling of the first pair of cells in the first zone, the IIN delivers the first voltage pulse to the electromagnet 16. When the current passes through the electromagnet 16, a magnetic field arises around it, which attracts the armature 18. In this case, the pin 22 presses on the tube 14 Acting as a press, the pin creates an overpressure pulse in the tube, which at a higher speed throws a portion of the meat into the joint of the tapes in the first zone. A portion

minced meat (its volume depends on the area of the bevel of the pin), presses the dough into the cells, forming dumplings shells, and fills them. The duration of the voltage pulse is designed so that at the time of closure of the cells, the current in electromagnet 16 drops to zero and the magnetic field disappears. The pin due to the elasticity of the plate 20 is returned to its original position and the tube 14 restores its shape. The pressure in the tube drops sharply for an instant, and the minced meat practically stops. At this point, the conjugate cells compress the edges of the dough shells, forming a dumpling with a filling.

After the drums rotate by 18 °, the first pair of cells of the second rows begins approaching. At this moment, the TIN delivers a voltage pulse to the electromagnet 17, creating a magnetic field around it. The electromagnet 17 attracts the anchor 19, which presses with its pin on the second tube 14, sharply increasing the forcemeat pressure in it. As described above, under the influence of a pressure pulse, a portion of the stuffing is injected between the tapes in the second zone and presses the dough into the first pair of cells of the second row. With a further rotation of the drums, the second pair of cells closes, blinding the edges of the shells, forming a second dumpling. At this moment, the IIN disconnects the voltage from the electromagnet 17. The magnetic field disappears, the armature 19 returns to its original position. The pressure in the second tube 14 drops sharply and the supply of minced meat to the second zone is stopped for a while. With further rotation of the drums, the first pair of cells of the first row diverges completely and the first finished dumpling 24 is pushed onto the conveyor 25, which will deliver it to the container 26. At this time, the second pair of cells of the first rows approaches the first zone. At the calculated moment, the IIN delivers another voltage pulse again to the electromagnet 16, after which a portion of the stuffing is injected from the first tube into the first zone, as described above. Subsequently, the cycle repeats. It is easy to calculate that for one revolution of the stamping drums the device produces about 20 dumplings (one average portion).

According to the scheme described above, a prototype device for the production of ravioli with four rows of cells on each drum was manufactured at the applicant’s enterprise. For this device, a breaker with four electromagnets for four discharge tubes was developed. The power of the electromagnets is turned on according to the following scheme: first for the first and third electromagnets, then, after a period of time, necessary for the rotation of the stamping drums by 18 °, for the second and fourth, etc. Testing the device showed a good result.

The proposed device for the production of ravioli has several advantages compared to the prototype. Firstly, during a pulsed ejection of minced meat, the dumplings shells have time to fill up with the filling. Secondly, pressure pulses break through the stuffing plugs in the tubes. Thirdly, the pulse chopper automatically reduces the consumption of minced meat at the moment when the cells are closed and the filling is not needed. Finally, a dough feeder in the form of a hopper with press and feed rollers provides a continuous supply of high-quality dough. Thus, the combination of continuous feeding of dough with pulse injection of minced meat increases the productivity of the device and the quality of ravioli.

The device described above meets the criteria of novelty and industrial applicability, in connection with which it is proposed to legal protection with a patent for a utility model.
