In FIG. depicts an installation for the production of short pasta.

The installation consists of a flour sifter I, a hopper for flour 2, a flour agitator 3, a gate 4, a batcher 5, a water dispenser 6, a dough mixer 7 with a humidifier tube 8, with a heating jacket 9, consisting of the first chamber 10 and the second chamber II, a screw the press 12 in the housing 13, the vacuum chamber 14 with the washer 15 and the bypass channel 16, as well as a vacuum gauge. .17 and a cooling jacket 18 and a three-auger screw 19 fixed to the output of the screw press shaft, pre-chamber chamber 20, pressure gauge 21, screw support in the form of a cone 22, a round matrix 23,

a cutting device 24 with interchangeable knives 25, a mechanism for adjusting the truncated cutting 26, combined with a blowing device 27. All nodes and. the elements are placed on the frame 28,

The flour sifter, installed at the beginning of the device, cuts through the flour and feeds it through the screw into the flour hopper.

Drum type flour dispenser provides accurate supply of flour of various grades (from grains to grade II). The plunger type water dispenser provides accurate and smooth adjustment of the flow rate of water supplied to the dough mixer. To improve the quality of the structure of the test massey dough mixer with a heating jacket. The design of the dough mixer, consisting of two chambers, reduces the dimensions of the installation, while ensuring continuous mixing of the dough required by the technology. The evacuation of the dough in the vacuum chamber increases the strength of pasta and gives them a yellowness. All this improves the quality of products, increases its shelf life.

A three-auger screw located at the exit of the screw press increases pressure, evens out the speed of the dough and reduces ripple in it.

An additional support at the exit of the screw press in the form of a cone, fixed in the center of the matrix and located in the pre-jacket chamber reduces the runout of the screw and thus increases its reliability and service life. In the pre-premix chamber, the test mass accumulates throughout the whole cross section, acquires uniform pressure and flow rate through the holes of the matrix.

The location of the pre-chamber chamber and the matrix along the axis of the screw simplifies the design of the installation and reduces its metal consumption compared to the prototype.

For pasta cuttings, a cutting device was used in the installation, on which one to four knives can be installed, depending on the type of product being manufactured. In addition, the cutting device is equipped with a mechanism for adjusting the cutting force over the entire area of the matrix. All this allows you to put pasta of different types in length and configuration.

The pressure head blowing device, combined with a cutting one and consisting of a fan with an engine and an air duct, makes drying the surface of pasta to prevent them from sticking together, as well as transporting the products to the table.

Installation works as follows. AtemoK with flour is mechanically tipped into the sifter I, passing through its sieve, the flour is fed with the screw into the flour bin 2. It is mixed with flour flour agitator 3, After filling the bin with flour, the jug 4 is opened, and it enters the drum-type museeh 5 batcher, which allows you to work on flour from grains to flour grade P. Dosed flour at the same time as water from the water dispenser 6 enters the dough mixer 7 through a humidifying tube 8, the water dispenser provides a smooth adjustment of water flow. To improve the quality of the structure of the test mass, the dough mixer is equipped with a heating jacket 9. Passing through the first chamber 10 only a portion of the incoming vyauki and water forms a tiny test mass. After passing through the second stone II, the entire volume of n water turns into a mass homogeneous in structure. Then the test mass enters the screw press 12 in the housing 13, where it is molded by the pressure created by the screw. After passing a third of the way along the screw, the mass enters the vacuum chamber 14, in the area of which the washer 15 is installed. A test tube is formed in front of the washer, which is pushed through the gap around the washer perimeter and the bypass channel 16 into the vacuum chamber. From the vacuum chamber, the air is pumped out by a vacuum pump, the degree of vacuum is measured by a vacuum gauge 17.

As the dough passes through the screw press, it is further pressurized and the temperature of the dough rises. The working temperature of the dough is maintained by means of a cooling jacket 18. The three-way outgoing screw 19, located on the end of the screw press shaft, increases pressure, evens out the speed of movement and reduces pulsations in the test.

Then the test mass enters the pre-chamber 20, where the movement speed still drops, and the pressure rises to the working one, which is measured by gauge 21. The airspace accumulates in the pre-chamber, bypassing the support in the form of a cone 22, which is fixed along the center of the circular matrix 23.

Then the test mass is pressed under pressure through the holes of the matrix for. the formation of pasta.

After that, the pasta is cut using a cutting device 24, equipped with interchangeable knives 25. The force of pressing the knives to the matrix is carried out by the mechanism for regulating the cutting force 26. The pasta pressed out through the matrix and cut by the device is subjected to preliminary drying and transportation in a pressure air stream using a blower 27 on the table in the cassette,

Compared with the prototype, the proposed installation has much smaller dimensions and weight. The width of the prototype is 2940 mm, utility model - 1720 mm; prototype length - 2920 mm, utility model - 2450; prototype height - 2940 mm, utility model 2100 mi; prototype weight - 3250 kg, utility model - S20 kg.
