Description

A useful model of the invention relates to techniques for volumetric dosing and automatic filling of liquid food products in a variety of containers with a capacity of 1.2 and 3 liters, and more particularly to vending machines for filling and selling fresh milk, thereby conveniently satisfying human needs.

There are many types of vending machines made with the possibility of volumetric dosing and automatic bottling and sale of various liquids, for example, hot coffee or tea, drinks and juices in disposable cups described in the inventions for patents No. 2241364 A47j 31/40, No. 2134987 A23F 5 / 00, No.2253899 G07F 13/10, 13/00 and No.3138635 7G07F 13/06. / 1 /

According to their design, they differ in individual elements, but all have basic blocks and units, namely, small containers for liquids and containers for various components that communicate with metering devices, compartments for disposable cups, devices for heating or cooling, a compartment for accepting money, automatic control units for the dosing, bottling and sale of various liquids and drinks.

However, they are not intended for the storage, dosing, bottling and sale of fresh milk in the individual packaging of the buyer.

There are also known automated vending systems for selling fresh or pasteurized milk, for example, ROUO, LUX, BOX, BAITA, MALGA, PENSILINA, MOBILE and ProMete A milk machines, which are produced by various foreign companies.

To fulfill their functional capabilities, vending machines are structurally composed of separate units and systems, which, through electronic control units according to a given program, automatically and in a certain sequence turn them on or off.

Structurally, the automaton is divided into the following groups. The refrigeration box (machine case) is the main space of the machine where the milk tank is installed, where it is stored and cooled.

Ventilation-type refrigeration unit with a temperature control system inside the machine’s chamber.

System for intermediate flushing of hoses and milk dispensing tip with cold water

A milk tank with a capacity of 100-120-300 liters of milk (depending on the model of the machine), on the upper horizontal surface of which the following devices are mounted:

- filler neck for milk;

- flushing neck for pouring flushing and cleaning agents;

- an electromechanical device for a drive mounted inside a tank with a blade, during rotation of which the milk is mixed;

- a pump with a dosing system, a hose and a tip for dispensing a portion of milk into the customer’s tank.

On the front panel of the machine there is a window for dispensing milk, a programming keyboard with an information display, buttons for dialing the volume of milk purchased, for starting and stopping milk dispensing, and other devices, in particular, a payment acceptance system.

Although well-known vending machines perform their functions, however, they also have a number of disadvantages, due to which a change in the quality indicators of fresh milk and, above all, acidity and bacterial contamination can occur.

The first drawback is that milk tanks do not have thermal insulation and, after filling them on the farms with fresh milk cooled to + 4 ° C, they are transported to the installation site of the machines, as a result of which the milk temperature can increase to + 10 ° C or more, especially in the summer , which will lead to an increase in the permissible acidity limit of milk over 16-17 ° Turner, and, consequently, to the creation of favorable conditions for the multiplication of E. coli and other microorganisms.

Another and most significant drawback is that vending machines do not have a special device for the neutralization of milk from pathogenic forms of bacteria immediately before filling into consumer containers.

In addition, the process of mixing milk is technically complicated due to the use of an electromechanical device to drive the mixer installed inside the body of the milk tank.

A search by the applicant for patents and a scientific and technical source of information [2] made it possible to establish that the applicant did not find an analogue source characterized by features of a utility model.

The present invention proposes a vending machine that eliminates these disadvantages inherent in conventional machines and, therefore, in terms of the combination of essential distinguishing features, it meets the criteria of "novelty."

The purpose of the invention is the creation of a vending machine in which the temperature of chilled milk is kept in a removable container for a long time and the portions of milk safe for human health are neutralized from pathogenic bacteria.

To achieve this goal, the vending machine is equipped with a special device for the bactericidal processing of milk, and the removable milk tank is made in the form of a double-walled frame, between the walls of which a thermally insulating resin is poured, moreover, there are two necks on the upper part of the tank and an explosive coupling with shut-off valve.

The invention is illustrated by drawings, where figure 1 - schematically shows the General internal structure of the vending machine, figure 2 - General view of a removable milk tank with a heat-insulating shirt in section, shown in figure 1 and figure 5; figure 3 is a General view of a device for the bactericidal treatment of a portion of fresh milk in the section shown in figure 1 and figure 5; figure 4 is a cross section along aa, depicted in figure 3; figure 5 is a schematic illustration of the connection of the components of the machine for portioning fresh milk, mixing it inside the tank according to the new principle of "milk-milk" and rinsing with cold water system (except for the tank), shown in figure 1.

According to this invention, Fig. 1 schematically shows the overall internal structure of a vending machine for portioning and selling liquid dairy products, which comprises a housing 1 made in the form of a sealed chamber, inside of which a removable milk tank 2 is installed, and a ventilation refrigeration unit is fixed on the side walls type 3 with a temperature control system inside the chamber, a pump with a dosing system 4, a device for the bactericidal treatment of a portion of milk 5, containers for pure water and g fake 7.

On the front side of the panel (like conventional vending machines) there is a window for dispensing milk 8 and a control unit for the operation of the vending machine 9 with an information display, programming keyboard, other devices, in particular, payment acceptance systems.

To maintain a constant temperature of fresh milk to + 4 ° C during storage, sale, and especially during transportation from farms in the summer, the milk tank of figure 2 is made in the form of a thermos with two walls 9 and 10, moreover, the inner wall 9 and other details vending machines that are in direct contact with fresh milk are made of stainless steel or plastic used in the food industry, and the space between the walls is filled with insulating material 11.

On the upper surface of the tank there is a neck 12 for filling it with milk, which is hermetically sealed with a lid 13 equipped with a breather (not shown), moreover, during transportation the breather closes, and after installing the tank in the machine’s body, it opens to equalize atmospheric pressure. Another neck 14, into which the tube 15 is mounted, to the fitting of which a flexible hose is connected from the pump - dispenser for the operation of mixing milk according to the new principle of "milk-milk", which eliminates the need for an electromechanical drive with a stirrer, and, therefore, simplifies the design of the milk tank. The neck 14 is equipped with a stopper plug 16, which closes during transportation.

In the lower part of the body there is a drain neck 17 in which a shut-off valve 18 is mounted, made in such a way that when the tip of the flexible hose 20 is screwed into the fitting 19, the shut-off valve opens and milk flows to the dispensing pump, and when the tip is turned out, the shut-off valve 18 closes blocking the access of milk. After turning the tip of the flexible hose 20, a plug plug (not shown) is screwed into the fitting.

The device for the bactericidal treatment of a portion of milk, shown in figure 3, contains a special cylindrical flask 21 made of stainless steel, on which perpendicular to the axial line in the horizontal plane there is a pipe 23 (section AA in figure 4) for introducing milk and a pipe 22 for milk yield.

A glass tube 26 is installed inside the bulb, and a bactericidal lamp 27 is placed in it. Seals 24 and caps 25 are provided for hermetically sealing the ends of the glass tube and the housing. The bactericidal lamp is connected to the circuit of the vending machine through the electrical connectors.

The device for bactericidal treatment 3 is installed in the upper part of the housing 1 higher than the window for dispensing milk 8 and is mounted on a panel with a slope for the complete discharge of milk from the flask into the customer’s container.

Figure 5 presents the connection diagram of the components of the machine to perform various technological operations. So for batch dosing and pouring fresh milk, the drain neck of the milk tank 2 is connected by a pipe 20 to the inlet pipe of the metering pump 4, and its outlet pipe through the pipe 28 is connected to the inlet pipe of the bactericidal milk processing device 5, while its outlet pipe is connected rigidly to a drain pipe 29, the tip of which is brought out from above through a window for dispensing milk.

To mix the milk inside the milk tank 2 according to the new principle of "milk-milk", the pipe 28 from the outlet of the metering pump 4 is connected by a flexible hose 30 to the pipe fitting mounted in the neck 14.

Local cold washing of the metering device 4, pipe 28, the device for the bactericidal treatment of milk 5 and the drain pipe 29 is carried out by taking clean water from a container 6 connected by a pipe 31 to the inlet of the metering pump 4. Dirty water is collected in a container 7 through a flexible hose 32, which is connected to the nozzle of the funnel 33, mounted on the lower shelf for installation of customer containers in the window for dispensing milk.

To control the consistency in time of the switching sequence and the duration of operation of each system, electromagnetic valves are mounted in the piping lines connected to the electronic system of the control unit, namely, in the dosing and bottling line of fresh milk - valve 34 and valve 35; in the milk mixing line inside the milk tank - valve 36 and valve 37 and the flushing line - valve 38 and valve 39.

According to this invention, a description of the sequence of operation of a vending machine for portioning and selling liquid dairy products is given with reference to the positions indicated in figures 1-5.

Previously, a full washing and sanitization of the inner and outer surfaces of the removable milk tank 4, as well as caps with a breather and plugs, is carried out at the dairy farm, moreover, the plug-cap on the drain pipe is screwed in before milk is poured.

Fresh milk cooled to + 4 ° С is poured into a milk tank with a volume of at least 70 liters. through the filler neck 12, and the air is removed through an opening in the tube 15 of the neck 14.

After filling the milk tank, the neck 12 is tightly closed by a lid 13, while the opening of the breather is closed; and a stopper plug 16 is screwed onto the neck 14 and all three necks are sealed.

Since milk tanks are equipped with a heat-insulating jacket, the temperature of fresh milk at + 4 ° C will remain for a long time, and therefore they can be transported to the installation site of vending machines by cars that do not have refrigerated compartments and over long distances (up to 200 km) even summer time.

After installing the milk tank 2 in the chamber of the machine case, the seals are removed, the stopper plug 16 is removed from the neck 14 and the tip of the flexible hose 30 is connected to the pipe fitting 15, and then the stopper plug is turned out of the fitting 19 and the flexible tip is screwed into it hose 20, while the shut-off valve 18 opens and milk can flow to the metering pump 4 when it is turned on.

To equalize the atmospheric pressure inside the milk tank 2, the cover 13 on the filler neck 12 is turned 180 °, while the breather opens.

Having connected the milk tank to the machine’s systems, the doors of the case are hermetically closed, the “start-stop” button is pressed on the control unit panel, while the air temperature control and adjustment system within + 4 ° C inside the machine’s chamber automatically turns on or off the ventilation unit 3 , and the rest of the electronic systems are in standby mode for performing operations according to a pre-programmed sequence and time.

When the consumer selects the desired volume of milk to be purchased on the control panel of the machine, he opens the door of the milk dispensing window and sets his individual capacity on the shelf under the tip of the pipe 30. After entering a certain amount of money into the money compartment, the consumer presses the button for dispensing the required volume of milk - 1 2 or 3 liters, the executive elements of the portion batching and milk filling system are automatically switched on in a certain sequence, namely, electromagnets open on pipelines 20 and 28 valves 34 and 37, while the remaining valves are in the closed position, in the device for the bactericidal treatment of fresh milk 5, the bactericidal lamp 27 is turned on, and then the dispenser pump 4. The dosing device draws in milk from the milk tank 2, which enters through pipeline 28 into the inside of the flask 21, where the milk is subjected to bactericidal treatment and, neutralized from pathogenic microbes, is discharged through a pipe 29 into an individual consumer container.

At the end of the process of selling a predetermined volume of milk of 1, 2 or 3 liters, the dispensing of milk automatically stops and if the buyer has entered an excessive amount of money, then in the compartment for receiving money he receives change.

After selling a portion of milk, the machine automatically switches on the local flushing system with the programmed frequency, while the valve 34 closes, the valves 36, 37 and 39 on the pipelines open and the metering pump 4 draws in portions of clean water from the tank 6, which rinses the pipeline 28, the inner surfaces of the bactericidal devices 5 of pipelines 30 and 29, from the tip of which water flows into a funnel 33 on the lower shelf of the milk dispensing window and is drained through a pipe 32 into a container 7 for used water.

The same organoleptic properties of fresh milk inside the milk tank are maintained by periodically mixing it, for which, at certain intervals, the valve 34 on the pipe 20 automatically opens, the valves 36 and 37 on the pipe 30, while the remaining valves are closed, the metering pump 4 and milk from the milk tank 2 is sucked in by the metering device, and through the pipe 30 is poured again through the tube into the milk tank 2.

The proposed vending machine for portioning and selling liquid dairy products allows for a long time to maintain a constant temperature of fresh milk chilled to + 4 ° C inside a removable milk tank, especially when transported in the summer due to the use of a heat-insulating shirt in its design and neutralizes from pathogenic microbes servings of milk immediately before its sale, which guarantees the preservation of the quality indicators of fresh milk sold, and, therefore, b safety for human health.

In addition, the machine provides for the mixing of milk inside a removable milk tank with milk itself, therefore, the use of an electromechanical drive with a stirrer is not required, which simplifies the design of the milk tank and its maintenance. INFORMATION SOURCES
