Description

Technical field

The claimed technical solution relates to equipment for servicing food spill points, and in particular to systems for cooling the beverage supply line.

State of the art

The prior art known selected as the closest analogue device for cooling a liquid [1].

The device taken for the closest analogue contains a thermally insulated tank, for example, with a capacity of 22.5 liters, filled with a coolant, for example, water, in which an evaporator pipeline with a frozen ice supply is placed on the periphery. The device for cooling the liquid contains a series-connected compressor, a condenser blown by a fan, a filter dryer and a capillary tube.

The spiral part of the pipeline of the beverage supply line intended for transporting liquid, in particular beer, from an airtight container (keg, barrel) to the dispenser is immersed in a tank filled with coolant.

The agitator pump is installed in the tank inside the spiral part of the piping of the beverage supply line. The external recirculation loop is made in the form of a pipe folded in two by a loop and placed inside a thermally insulated tubular collector, where it adjoins the pipeline with an already cooled drink, while the supply and return pipes of the external coolant recirculation loop are located inside the coolant reservoir.

The piping of the beverage supply line is connected to an autonomous external source of supply of liquid under pressure.

A thermal relay is mounted in the coolant tank, which is electrically connected to the compressor and the condenser fan motor, which, when the coolant in the tank is cooled to a predetermined temperature, turns off the compressor and the condenser fan motor.

The agitator pump provides intensive heat exchange between the heat carrier in the tank and the heat exchanger piping, and also pumps water in the python (insulated pipelines that connect the cooler to the dispenser) to maintain the temperature of the drink in the pipelines and cool the dispenser.

The disadvantages of the closest analogue is the constant operation of the agitator pump, regardless of changes in product temperature in the beverage supply line.

A task

To optimize the supply of electricity for the operation of the agitator pump depending on the temperature parameters of the beverage in the beverage supply line.

Technical result:

- reducing the energy consumption of the cooling system of the beverage supply line by turning the agitator pump on and off, depending on the temperature of the liquid in the pipe of the heat exchanger of the beverage supply line;

- increase the service life of the pump-mixer due to reduced wear of its parts, due to the occurrence of periods of disconnection of its power supply;

- improving the geometry of the ice field and, as a consequence, increasing the bank of ice that is frozen and maintained during operation, by reducing the areas of eroded ice in places of rapid movement of water, due to periods of power outage of the agitator pump.

Disclosure of a technical solution

In the cooling system of the beverage supply line, which contains a refrigerant circulation line (2a), an external recirculation circuit (5c) of coolant (10) hydraulically connected to the coolant reservoir (1), into which the evaporator pipe (2) of the coolant circulation line is immersed (2a), at least one pipe of the heat exchanger (6) of the beverage supply line (6a), the agitator pump (5), it is proposed, in addition to the system, to introduce a relay control unit (7), which interacts with at least one sensor (7a) installed in the system to remove Ia physical parameters of the fluid in the beverage supply line (6a), the relay control unit (7) is adapted to periodically activate and deactivate the pump-mixer (5).

Industrial applicability

The agitator pump (5) is, made in one housing, a pump for transferring the heat carrier (10) to the external recirculation circuit (5c) and a mixer for intensifying heat transfer between the heat carrier (10) and the heat exchanger pipes (6) in the tank (1) . The external recirculation loop (5c) is used to cool the beverage supply line (6a) in the area between the heat exchanger (6) and the casting column (13), as well as the casting column (13) itself. It is allowed to operate the cooling system of the beverage supply line with a pump and mixer made as separate components.

The sensor (7a) for recording the physical parameters of the liquid in the beverage supply line (6a) is a device for reading and transmitting the state parameters of the beverage to the relay control unit (7), which can be either temperature values or the presence of movement of the beverage in the beverage supply line ( 6a).

The relay control unit (7), designed to activate and deactivate the agitator pump (5), is represented by the example of a thermostat (7b) with a sensor (7a) for measuring liquid temperature (Fig. 1) and by the example of a microprocessor (7c), which through the power switching module (7e) controls the electric relay (7d) (Fig. 2) and receives the readings of the sensors (7a) to record the movement of liquid in the beverage supply line (Fig. 2).

The implementation of the relay control unit (7) with a microprocessor (7c) and the power switching module (7e) can also be implemented in a circuit with a sensor (7a) for measuring liquid temperature, however, in FIG. 1 not shown.

The heat rail (9) is made of a material with high thermal conductivity and consists of two parts (9a) fixed by fastening (9b) on the pipelines of the heat exchangers (6). A mounting hole (9c) is made in the thermal bus (9) for mounting the sensor (7a), for taking temperature readings (Fig. 3). The heat bus (9) is installed at the inlet of the pipelines of the heat exchangers (6) into the tank (1) to create thermal contact between the pipelines of the heat exchangers (6) and the sensor (7a) to take temperature readings. The use of a heat bus allows the use of one sensor (7a) for two or more pipelines of heat exchangers (6).

If only one pipe of the heat exchanger (6) is used, the heat bus (9) may not be installed, and the sensor (7a) is mounted in the tank (1) of the coolant (10) directly to the inlet section of the pipe of the heat exchanger (6) to measure the temperature of the liquid.

It is possible that instead of a heat bus (9), a separate sensor (7a) is connected to each pipeline of the heat exchanger (6) to take temperature readings. When using the embodiment of the system of FIG. 2 - a sensor (7a) for detecting the movement of liquid is installed on any part of the beverage supply line (6a).

The technical solution is presented by the example of a cooling system for a beverage supply line, in which the refrigerant circulation line (2a) contains a hydraulically coupled and sequentially installed compressor (3), a condenser unit (4), a filter drier (11), an expansion device (11a) immersed in coolant reservoir (1) (10) evaporator (2); an agitator pump (5) immersed in the coolant reservoir (1) (10), interfaced with the supply and return pipelines (5a and 5b) of the external recirculation loop (5 s) of the coolant (10); a relay control unit (8) with a sensor (8a) for controlling the compressor (3) and the condenser unit (4); relay control unit (7) with sensor (7a).

Each of the two shown in FIG. 1 and FIG. The 2 beverage supply lines (6a) contain a hydraulically connected and connected in series beverage source (12), a heat exchanger pipe (6) immersed in a coolant reservoir (1), a tapping column (13) with a tapping tap (14), and a beverage reservoir (fifteen).

After filling the tank (1) with coolant (10), electricity is supplied through the contact of the power line in the relay control unit (8) to the compressor (3) of the refrigerant circuit (2a) and the fan motor (4a), and through the contact of the power line in the relay block control (7) to the agitator pump (5).

The coolant (10) (water) in the tank (1) begins to cool, reaches the phase transition temperature and ice begins to freeze on the evaporator. After cooling the coolant (10) in the tank (1) or freezing a predetermined ice bank on the evaporator pipe (2), the cooling system for the beverage supply line is ready for operation (bottling). The thermal sensor (8a) detects the temperature below the threshold temperature set in the relay control unit (8), as a result of which, the thermostat (8b) opens the contact of the compressor power line (3) and the fan (4a) of the condenser unit (4). Blowing of the condenser pipe (4b) stops.

In the relay control unit (7), in the case of using a sensor (7a) to measure liquid temperature (Fig. 1), a threshold temperature value is set, below which the agitator pump (5) turns off, and a temperature threshold value is set above which the agitator pump is switched on (5). After the start of the spill due to the arrival of a warm drink, the temperature of the heat exchanger pipe (6) increases, which is sensed by the sensor (7a) directly in contact with the heat exchanger pipe (6) or through the heat bus (9). When the temperature at the installation location of the sensor (7a) reaches the switch-on temperature of the agitator pump (5), the thermostat (7b) closes the contact of the supply line of the agitator pump (5) and the agitator pump (5) is activated. The mixer pump (5) continues to operate both during and after the spill, until the temperature at the sensor installation site (7a) reaches the set temperature at which the thermostat (7b) opens the contact of the supply line of the mixer pump (5) and the agitator pump (5) is deactivated.

In the case of using a sensor (7a) to detect the movement of liquid in the beverage supply line (6a), the command to turn on the agitator pump (5) by the microprocessor (7 s) is sent to the power switching module (7e) after the spill starts, and to turn it off after stopping spill.

During operation of the mixing pump (5), the coolant (10) is supplied to the external recirculation circuit (5c) through the supply pipe (5a) and discharged into the tank (1) through the return pipe (5b) to cool the beverage supply line (6a) in the area between the heat exchanger (6) and the casting column (13), as well as the column itself (13).

In order to avoid heating the chilled beverage in the beverage supply line (6a) during the absence of spills when the agitator pump (5) does not work and, as a result, the coolant (10) from the tank (1) is not supplied to the external recirculation loop (5c) , the relay control unit (7) can activate the agitator pump (5) for a period specified by the setpoint, if the idle time of the agitator pump (5) reaches the value of the response setting of the relay control unit (7). The operating mode of the relay control unit (7) is also possible when the activation and deactivation of the agitator pump (5) is performed according to the set operating time and parking time without taking into account the readings of the sensor (7a).
