Description

The invention relates to the confectionery industry, namely to the equipment for the production of flour confectionery and whipped sweets.

The aim of the invention is to expand the technological capabilities and improve the quality of aerated fat.

The drawing shows schematically the proposed installation, a general view.

The installation for producing aerated fat contains a receiving tank 1 for receiving molten fat, a scale 2, a pump .3 for pumping fat, a tank 4 for tempering, a fat dispenser 5, a device 6 for saturating fat with air, an air-fat compressor 7, an expansion diffuser 8, a fat cooler 9, a U-shaped nozzle 10, aerated fat dispenser 11, plasticizer 12, as well as pipelines for transporting fat. A flexible element 13 is installed on the pipeline between the tank 1 and the pump 3, and the pipeline between the pump 3 and the tank 4 has a spool 14. In addition, the tank 4 is equipped with a level sensor 15.

The device 6 for saturating the fat with air is made in the form of a cylinder with three inlet nozzles for introducing air 16, molten fat 17 and plasticized fat 18 and one outlet nozzle 19, made in the form of a conical nozzle, and on pipelines connected to the nozzles 17 and 18 , valves 20 and 21 are installed respectively. To, the air inlet nozzle 16 is connected, including a filter 22, a control valve 23 and a rotameter 24.

Paci c diffuser 8 contains a discharge nozzle 25, a cone-shaped channel 26 and a discharge nozzle 27.

In the fat cooler 9, a working space is formed between the outer cylinder 28 and the displacement drum 29 equipped with knives 30. At the outlet of the cooler 9 there is a spool 31 installed by a U-shaped branch pipe 10. The aerated fat dispenser 11 has a level sensor 32.

The plasticator 12 contains a system of screws 33 for kneading the blocks of solid fat 34 and is equipped with a loading conveyor 35.

The plant for producing aero fat provides aerated fat based on melted anhydrous fat and based on blocks of solid hydrous fat.

Upon receipt of aerated fat from molten anhydrous fat installation works as follows.

Molten anhydrous fat is loaded into receiving tank 1 from storage at 40 ± 3 ° С. With the help of scales 2 register the amount of incoming fat. For normal operation of the balance 2, the pipeline between the tank and the pump 3 has a flexible

element 13. Then from tank 1 pump 3 fat is pumped into tank 4 to temper the fat. Upon reaching a predetermined level of fat in the tank 4, the sensor 15 gives

a signal to switch the spool 14 to return the fat to the tank 4. When the fat level in the tank 4 is lowered, the sensor 15 switches the spool 14 to feed the product again to the tank 4. The maintenance of the fat level is necessary for stable operation of the dispenser 5.

The tamped to 42 ± 1 ° C fat from the tank 4 is continuously dosed with the dosing unit 5 into the unit 6 to evaluate the fat with air. At that, the valve 20 is open for passage, and the valve 21 is closed by the pipeline from the plasticizer 12. From the device 6 for saturating the fat with air, the fat is carried through the outlet 19 by the supercharger 7. Due to the fact that the capacity of the supercharger 7 is 10-20 times more performance

0 a fat dispenser 5, in an installation 6 for saturating the fat with air, a vacuum of 0.065-0-075 MPa is created. This ensures that air flows from the atmosphere into the installation to saturate the fat with air through

5 filter 22, a control valve 23, a rotameter 24 and an inlet 16.

By means of the filter 22, the atmospheric air is cleaned from dust, the valve 23 regulates the amount of air drawn in, and the rotameter 24 measures the amount of air in this air.

The mixture of fat with air from the pipe 19 passes through the compressor 7 and is fed into the expanding diffuser 8. The cross-sectional area of the discharge pipe 25 is 2-3 times less than the cross-sectional area

5 sections of the discharge port 27. Therefore, the kinetic energy of the fat-air mixture is converted into an increase in static pressure of up to 0.3 MPa, which is necessary for the mixture to pass through cooler 9, and when the mixture moves in a cone-shaped channel 26, a turbulent flow is formed, which increases the dispersion of air bubbles and uniformity Fatty mixture.

From the diffuser 8 fat-air mixture

g under pressure enters the working space of cooler 9. Here the mixture moves in a thin layer between the outer cylinder 28 and the displacing drum 29. At the same time, the mixture is cooled by the walls of the cylinder 28, intensively mixed but 30 from the inlet to the outlet of the cooler with temperature .

Next, aerated fat through the spool

31 and the U-shaped port 10 enters the dispenser 11, from which it is dosed to

5 issue for subsequent technological operations. In case of a break in the release of fat when raising its level in the dispenser, the sensor

32 signals to switch the spool

31dl return the fat in the tank 1. When the level of fat in the dispenser is lowered 11 sensor

32 gives the signal to switch the spool 31 to supply the fat to the dispenser.

Upon receipt of aerated fat from blocks of water-containing (or anhydrous) solid fat installation works as follows.

With conveyor 35, fat blocks 34 are loaded into plasticizer 12. In the latter, using a system of screws 33, solid fat is kneaded and tempered to 26 ± 1 ° C. Fat acquires a fluid consistency and with screws 33 is continuously metered into unit 6 for saturating fat with air. In this case, the valve 21 is open to the passage, and the valve 20 is closed to the pipeline from the dispenser 5. The subsequent technological operations are carried out similarly to the above described operation of the installation when receiving aerated fat from molten fat. Upon completion of work or in case of overflow of the receiving tank 1, returning the aerated fat to the plasticizer 12 stops loading the blocks of solid fat 34, releases the plasticizer from the product, then the valve 20 is opened to the passage and the pipeline 21 closes the pipeline from the plasticizer. Further, all the equipment, prior to the release of the receiving tank 1 from the product, acts in the same way as the installation described above in obtaining aerated fat from molten fat.

The invention makes it possible to provide conditions for the treatment of solid water-containing fats, to reduce the density of fat by 1.3–2 times, to increase the specific surface of fat by 1.5–2 times, and, consequently, to improve the physical and technical indicators of the quality of fat.
