The drive of the mixing unit (gear motor) 6 is installed permanently in the casing 2 of the machine.

Milk tank 4 (Fig. 3, 4) is a cylindrical tank 22 with mounted on it a hydraulic system 5 for dispensing and dispensing milk. On the lid 23, which has a tight seal 24 with a tank, an electric motor 25 with a pump 26 and a flow meter 27 is installed, there are hydraulic tubes 28 with a dispenser nose (usually food-grade silicone with a conditional passage of 8-10 mm) for collecting milk from the tank and feeding it into the zone dosing. At the inlet of the pump 26 in the immediate vicinity of the hydraulic tube is installed a mechanical check valve 29.

The lid has a filler neck 30 for filling with milk, a spherical washing head 31 with a spray angle of 360 degrees to connect the milk tank to the CIP sink.

In the center of the lid 23 of the milk tank there is a sealing element 32 (Fig. 5), made in the form of a plug 33 with an opening through which the rod 34 of the mixer passes. At the upper end of the rod, a quick-detachable connection 35 (Fig. 6), for example, a bayonet mount, is installed to connect the stirrer rod 34 to the drive of the mixing unit 6, which has a corresponding pin on the output shaft of the gear motor.

Milk tanks are washed centrally at a sanitization unit, which is a small-sized CIP-sink with a volume of washing liquid tanks calculated based on the requirement of simultaneous washing of several milk tanks.

Machine for the sale of milk works as follows.

Sanitized, refilled milk tank 4 is installed in the vending machine 1. For this, it slides into the thermostatic housing 2 of the machine 1 along the slideways 20 to the stops 21 installed in the bottom of the housing, with the help of which it is centered relative to the drive unit (gear motor) of the assembly mixing 6. The sealing element (plug) 33, made of an elastic material and located in the cover 23 of the milk tank 4, is removed, the stirrer rod 34 is lifted up and by means of a quick coupling, for example a bayo net 35, is connected to the drive of the mixer 6, which is permanently mounted in the machine case 2 above the milk tank 4. At the same time, the sealing element 33 remains hanging on the rod 34, and the rod 34 can rotate, mixing milk, but not in contact with the lid 23 of the milk tank. Thus, the errors of installation and centering of the milk tank 4 relative to the drive of the mixing unit 6 are compensated.

The dosing and dispensing system of milk 5 is connected to the dispensing window 7 and to the electronic control unit 15.

Bottle dispenser 12 is filled with an empty container.

The device for maintaining the microclimate 10 provides a certain fixed temperature in the compartments of the thermostatic housing 3.

The buyer who wishes to purchase milk on bottling makes the necessary payment using cash and / or electronic identifiers. The windows for dispensing milk and empty bottles automatically open, the sound module for interactive assistance to the buyer 19 prompts the procedure.

According to his desire, the buyer can first purchase a bottle by pressing the “Bottle” key on the remote control 16, after which the bottle dispenser 12 issues an empty bottle to the bottle dispensing window 13. Then he installs the bottle he bought or has his own in the milk dispensing window, presses the “ Milk".

After the payment is received, the electronic control unit 15 transmits a signal to the milk dispensing system of the milk tank 4, the electric motor 25 of the pump 26 is turned on, and milk from the milk tank 4 through the milk dispensing system 5 starts to flow into the dispensing window 7 and then to the consumer’s packaging. The control of the filling of the container is carried out through the milk dispensing system of the milk tank 4 by the electronic control unit 15.

After the signal about the receipt of the paid amount of milk in the customer’s packaging, the electronic control unit 15 receives a signal in the milk delivery system of the milk tank 4, the electric motor 25 of the pump 26 is turned off, and the milk supply to the consumer’s packaging is stopped. In the case of cash payment, the machine will issue the required change after pressing the "Change" button on the remote control 16.

After the end of the milk dispensing session and a voice warning, the milk dispensing windows and empty bottles are automatically closed, a signal is received from the electronic control unit 15 and the dispensing window 7 is flushed using the intermediate water flushing system 8 with clean water. The use of a spherical spray washing head 9 with a spray angle of 360 degrees ensures high-quality washing of the entire internal volume of the dispensing window 7, due to pulsed spraying of washing water in all directions.

In order to prevent the formation of ice on the dispensing window 7 in winter and to prevent the automatic closing of the window from failing, the microclimate maintenance device 10 is provided with an additional heater for the dispensing window, made for example in the form of a heat gun 11 installed under the dispensing window 7.

Issuing and stopping the dispensing of milk in the machine is carried out by turning on and off the electric motor 25 of the pump 26 of the dosing and dispensing system of milk 5, which simplifies the design of the machine, because the use of various kinds of solenoid valves is not required. When the tank of the milk tank 4 is full, it is not difficult to start the pump 26 of the dosing system, however, as the milk is sold, the level in the tank decreases, and starting the suction pump 26 causes certain difficulties. To prevent spontaneous discharge of milk from the pump 26, after it is stopped, through the tubes 28 back to the milk tank 4 and to facilitate starting during the next cycle of milk delivery, a mechanical check valve 29 is installed in the immediate vicinity, ensuring constant filling of the working cavities of the pump 26 with milk . The optimal location of the check valve 29 is established experimentally.

After emptying the milk tank 4 or in case of expiration of the storage of milk in the machine 1 (in practice - 2 ... 3 days), the milk tank 4 is transported to the sanitization unit. The remaining milk is drained from the tank, the milk tank itself is connected to the supply and return circuits of the CIP-sink, and the supply circuit is connected to a spherical spray head 31 with a spray angle of 360 degrees installed in the cover 23 of the milk tank 4, and the discharge circuit to the nozzle of the milk dispenser .

Compared with the prototype, the proposed utility model has a simpler design, in particular of a milk tank; a simpler milk dosing system that does not require the use of various types of electromagnetic valves, thereby reducing the level of unit costs for manufacturing, maintenance and repair; greater sanitary safety due to better washing of the dosing window and the possibility of connecting the milk tank to the CIP sink; simpler and more reliable protection of the automatic dosing window from the formation of ice in the winter; the ease of installation and centering of the milk tank in the machine increases the ease of maintenance.
