about vo

The invention relates to the food industry and can be used in everyday life and in public catering enterprises for preparing beverages from food products.

A device is known for ultrasonic extraction of medicinal substances from plant materials 1. The device increases the yield of active substances due to the action of ultrasound in a liquid medium on the raw material.

A well-known mini-cafe machine 2, which provides the brewing of coffee beverage and tea by express technology.

A device for preparing a coffee drink 3 using the expresso technology is known, which provides water preparation, extraction of active substances from raw materials when water flows through coffee, however, due to the short-term contact of water with coffee powder, a large amount of raw materials is necessary to achieve high taste qualities of the beverage, t .e. large losses of coffee when brewing in this device.

The purpose of the invention is to increase the extraction efficiency.

To achieve this goal, a beverage preparation unit comprising a water supply tank in series, a pump, a boiler with a heater, a thermal switch with water and steam valves and a brewing unit connected to one of the latter with a percolator to place the crushed product to be extracted into it and a control unit for the pump and the boiler is further provided with an ultrasonic generator and a piezoceramic transducer for acoustic impact on the extracted product, moreover an ultrasonic generator connected to a control unit and a piezoceramic transducer.

In FIG. 1 is a functional diagram of a beverage preparation plant; in FIG. 2 - functional diagram of the boiler.

The device consists; 1 - nutrient tank; 2 - pump; 3 - boiler; A - brewing unit; 5 - percol trp; 6 - control unit; 7

ultrasonic generator; 8 - piezoelectric transducer.

The boiler consists of: 9 - boiler boiler; 10 - inlet valve; 11 - inlet pipe; 12 - exhaust pipe; 13 - exhaust valve; 14 - electric thermal water heater; 15 - temperature relays.

The installation contains a nutrient tank 1 with drinking water, connected by a pipe through a pump 2 to a boiler 3 connected to a brewing unit 4, in which

a percolator 5 with crushed product is inserted, as well as a control unit 6 for pump 2, a boiler 3 and an ultrasonic generator 7 connected to a piezoceramic transducer 8, which is acoustically contacted with the product in a percolator 5, which is immersed, connected to the AC mains in prepared water, poured into the inner cavity of the brewing unit 4.

Installation works as follows.

The supply tank 1 is filled with water, the control unit 6 is connected to the AC mains and to the ground terminals. After starting up the control unit b, including a pressure 2, which fills with water from the tank 1 via the boiler 3 pipeline, the equipment of the latter is turned on: a water heater 14 and

thermal relay 15, which raise the water temperature to 92 ° C, the on state of the heater is indicated on the front panel of the control unit 6. Filling the percolator 5 with a portion of the crushed product and installing it in the brewing unit 4, the latter is closed with the outlet valve 13 of the boiler 3. The water prepared in the boiler 3 is poured into the internal cavity of the brewing unit 4, after this 0 the control unit 6 includes an ultrasonic generator 7, which feeds the ultrasonic frequency voltage to the piezoceramic transducer 8. The transducer 8 creates an acoustic field in a liquid, mixing the crushed product and extracting the active substances from the grains. The solution, filtered through a percolator 5, is poured from the brewing unit 4, through a drain pipe, into a cup or receiving thermos. After

stopping the supply of Portions of water from the boiler 3, the control unit 6 turns off the ultrasonic generator 7, replenishes the supply of drinking water in the boiler 3 from the tank 1 with the pump 2 and maintains its temperature at a predetermined level.
