Description

Beverage providing system having circulation characteristic

The present invention relates to a beverage supply system having circulation characteristics. In particular, the present invention relates to a beverage supply system for supplying a beverage to a plurality of tables using a circulation pipe.

In general, restaurants provide beverages such as drinking water, beverages, alcoholic beverages, etc., directly to the guest table, and the beverage provision method has the following disadvantages. First of all, hiring a sufficient number of employees in order to quickly and smoothly serve a drink ordered by a guest, thus hiring a sufficient number of employees, results in an increase in labor costs and raises the overall service cost. In addition, in the case of a beverage transported in a bottle such as a drink or alcohol, a safety accident may occur due to the breakage of the bottle. In addition, when calculating the cost to be paid by the guest based on the number of beverage bottles and the number of liquor bottles provided to the guest, an error in calculation may occur due to an incorrect number of bottles. To solve these shortcomings, a beverage automatic supply device that can automatically supply beverages to each table can be considered.

1 is a diagram illustrating an automatic beer supply device.

The central supply unit 110 is provided with a beer storage tank 120 for storing beer and a compressed gas tank 130 for providing compressed gas. Beer supplied by the central supply unit 110 is provided to the tables TAB1, TAB2, and TAB3 through piping. In each of the tables TAB1, TAB2 and TAB3, the valves VAL1, VAL2 and VAL3 are opened or closed according to the customer's order. Meanwhile, the counter 140 calculates how much beer is provided to which table and calculates a cost to be paid by the customer. By adopting this automatic beer supply system, beer can be automatically supplied to each table (TAB1, TAB2, TAB3), thus reducing the number of employees required, and eliminating the need for bottled beer. This cost to be paid is simply calculated by the counter 140.

However, in such beer automatic supply device, since beer flows from the central supply unit 110 to the respective tables TAB1, TAB2, and TAB3 in only one direction, it remains in the pipe when maintenance work is required or after the restaurant is closed. Beer can not be recovered to the central supply unit (110). Inevitably, after maintenance work is required or the business is closed, the beer remaining in the pipe is taken out to the tables TAB1, TAB2 and TAB3 and discarded. In general, about 30% of the total amount of beer supplied by the central supply unit 110 is considered to be discarded as the remaining beer. The larger the area of the restaurant, the greater the total length of the pipeline, so the problem of disposal of remaining beer will become more serious. In addition, in the beer automatic supply device as described above, it is not easy to clean the pipe due to the one-way characteristic, and it is expensive to carry out the washing operation, so that the washing operation is not frequently performed.

By sharing, the energy efficiency of a beverage supply system can be improved.

If the restaurant is closed or maintenance is required, compressed air can be used to effectively recover the remaining beverages in the circulation piping, even if the total length of the circulation piping is quite long.

Since the cleaning liquid can be easily washed by flowing the cleaning liquid into the circulation pipe and circulating the introduced cleaning liquid along the circulation pipe and the bypass pipe, the beverage supply system can be operated in a clean sanitary environment.

The apparatus may further include a central controller which controls the operation of the temperature controllers TCp and TCs through the temperature control signals STCp and STCs. Automatic valves shown in FIG. 2 (ILV, OLV, PVp1, PVp2, PVs1, PVs2, SV1 to SV5, BV1 to BV5, TVp1, TVp2, TVs1, TVs2, AV1, AV2, EVa, EVb, BPV, DVa to DVd) ) May be implemented as a solenoid valve whose opening and closing is controlled by a central control unit. In FIG. 2, the black filled automatic valves PVs1, PVs2, TVs1, TVs2, AV1, AV2, EVa, EVb, BPV, DVa to DVd represent the closed automatic valves and the white filled automatic valves (ILV). , OLV, PVp1, PVp2, SV1-SV5, BV1-BV5, TVp1, TVp2) represent the automatic valves in the open state. On the other hand, when the beverage supply system according to a preferred embodiment of the present invention is implemented as a manual system valves shown in Figure 2 (ILV, OLV, PVp1, PVp2, PVs1, PVs2, SV1 ~ SV5, BV1 ~ BV5, TVp1 Control of each of TVP2, TVs1, TVs2, AV1, AV2, EVa, EVb, BPV, DVa ~ DVd, operation of pressure pump (PCp, PCs) and operation of temperature controller (TCp, TCs) Can be.

In FIG. 2, the main circulation pipe disposed along the main circulation path from the outlet valve OLV to the inlet valve ILV includes a grinder SHT, pressure pump parts PCp and PCs and related valves PVp1, PVp2, CVp, PVs1, PVs2, CVs), equalization valve (UFV), maintenance automatic valves (SV1 to SV5), temperature control unit (TCp, TCs) and their associated valves (TVp1, TVp2, TVs1, TVs2), and Safety valve (SFV) is inserted. The main circulation pipe is connected to a compressed air pipe having air compressor units AC and AR and associated valves AV1 and AV2, and the cleaning liquid supply units DST and WTR and related valves. The cleaning pipes having EVa and EVb are connected, the drain pipes having respective drain valves DVa to DVc are connected, and the bypass pipes having a bypass valve BPV. Pass piping is connected, and a plurality of pressure sensors PSa to PSd and a plurality of temperature sensors TSa to TSd are connected.

The main circulation pipe supplies the beverage circulated along the main circulation path to the respective tables TAB1 to TAB5 through the respective table automatic valves BV1 to BV5. For example, in response to an order from a table (TAB1, TAB2, TAB3, TAB4 or TAB5), the central control opens the table automatic valve BV1, BV2, BV3, BV4 or BV5 and in that state the table (TAB1, When the customer of TAB2, TAB3, TAB4 or TAB5 opens the table manual valve (MV1, MV2, MV3, MV4 or MV5) of the table, a drink in the main circulation pipe is provided to the customer of the table. The flow meter (FQ1, FQ2, FQ3, FQ4 or FQ5) of the table measures how much beverage is provided to the table and transmits the measurement result to the central control unit. The central control unit calculates the cost to be paid by the guests of the table based on the measurement result.

The beverage storage tank BST stores the beverage injected through the beverage injection port Bin. The beverage storage tank BST receives the beverage from the main circulation pipe through the inlet valve ILV or sends the beverage out through the outlet valve OLV to the main circulation pipe. In addition, the beverage storage tank (BST) is a storage temperature controller (TCa) with a temperature control function (heat insulation function, cooling function, heating function) to maintain the temperature of the beverage stored in the beverage storage tank (BST) within a predetermined temperature range ) May be provided. For example, a beverage storage tank (BST) for storing cold beverages (drinks served cold, such as shochu) requires warm and cooling functions, and heated beverages (drinks served hot) In the case of a beverage storage tank (BST) for storage, a heat retention function and a heating function are required. The temperature of the beverage stored in the beverage storage tank BST is sensed by the temperature sensor TSc, and the temperature sensing data is transmitted to the central controller. The central control unit controls the operation of the temperature regulating units TCp and TCs via the temperature control signals STCp and STCs based on the temperature sensing data from the temperature sensors TSa, TSb and TSd [details of FIGS. 5A and 5B]. According to the preferred embodiment of the present invention in terms of controlling the operation of the storage temperature controller TCa provided in the beverage storage tank BST based on the temperature sensing data from the temperature sensor TSc. The beverage supply system can be considered to have dual temperature control functions (dual cooling or dual heating).

If a beverage storage tank (BST) stores cold beverages (coldly served beverages such as shochu) at low temperatures, if some of the frozen beverages are frozen, the ice fragments will prevent the beverages from circulating along the main circulation pipe. Can be. In order to prevent such a circulation disturbance, the agitator (AGT) first agitates the cooling beverage stored in the beverage storage tank (BST) to prevent the cooling beverage from freezing. (SHT) crushes the ice debris contained in the beverage flowing into the main circulation pipe through the outlet valve (OLV).

The level indicator LG connected to the beverage storage tank BST indicates how much beverage is left in the beverage storage tank BST. As the level of the beverage in the beverage storage tank BST is lowered by the consumption of the beverage, air enters the beverage storage tank BST through the check valve CVa. If it is necessary to drain the beverage stored in the beverage storage tank BST, the drain valve DVd can be opened to drain. The flanges F1 to F4 can be released to separate the beverage storage tank BST from the piping. Hereinafter, operation modes of the beverage supply system according to an exemplary embodiment of the present invention will be described with reference to FIGS. 3A to 3D.

FIG. 3A shows a mode of operation of the beverage supply system shown in FIG. 2, FIG. 3B shows a recovery operation mode of the drink supply system shown in FIG. 2, and FIGS. 3C and 3D show the drink supply system shown in FIG. 2. Indicates the cleaning operation mode.

In the operating mode as shown in FIG. 3A, the compressed air pipe associated with the air compressor units AC and AR, the cleaning pipe associated with the cleaning liquid supply units DST and WTR, and a bypass valve BPV are provided. The bypass line is closed and the main circulation line is open. Therefore, in the operating mode, the beverage supplied by the beverage storage tank BST is provided to the respective tables TAB1 to TAB5 via the pressure pump units PCp and PCs, and is not consumed in the tables TAB1 to TAB5. The undrinked beverage is returned to the beverage storage tank BST via the temperature controller TCp and TCs.

In Figures 2 and 3A the pressure pumps PCp, PCs provide pressure for circulating the beverage along the main circulation pipe. The larger the area of the restaurant where the beverage supply system is installed, the greater the total length of the main circulation line and the total number of tables will increase the pressure capacity required to circulate the beverage along the main circulation line. In view of this aspect, the pressure pump portion in the beverage supply system according to the preferred embodiment of the present invention is provided with one or more pressure pumps to ensure the required pressure capacity corresponding to the total number of tables and the total length of the main circulation pipe. . The pressure pump part in FIG. 2 has two pressure pumps PCp and PCs. For example, when the beverage consumption at the tables TAB1 to TAB5 is low, only the first pressure pump PCp is operated. When the beverage consumption at the tables TAB1 to TAB5 is high, the first pressure pump ( PCp) may be operated together with the second pressure pumps PCs. The central controller controls the operation of each of the pressure pumps PCp and PCs through the pressure control signals SPCp and SPCs based on the pressure sensing data from the pressure sensors PSa to PSd connected to the main circulation pipe.

4 illustrates a logic circuit CONTROLLER of the central control unit for controlling the operation of the pressure pumps PCp and PCs shown in FIG. 2.

The logic circuit CONTROLLER of FIG. 4 is responsible for maintaining the pressure for circulating the beverage within a predetermined pressure range L-H. For this purpose, the logic circuit (CONTROLLER) is the upper limit comparator (COMH) for comparing the pressure sensing data from the pressure sensor PSa with the upper pressure limit (H), and the lower limit comparator for comparing the pressure sensing data from the pressure sensor PSa with the pressure lower limit (L). (COML), the delay signal DEL for delaying and outputting the pressure control signal SPCp_PCp start indicating the start of operation of the first pressure pump PCp by 30 seconds, and the output signal and delay signal of the upper limit comparator COMH ( AND gate (A) for performing logical AND operation on the output signal of DEL), AND gate (B) for performing logical AND operation on the output signal of the lower limit comparator (COML), and the output signal of the delay unit (DEL), and upper limit comparator The output signal of COMH, the pressure control signal SPCp_PCp start indicating the start of the operation of the first pressure pump PCp, and the pressure control signal SPCs_PCs start indicating the start of the operation of the second pressure pump PCs are logic. AND gate (C) outputted by AND operation, and The output signal of the lower limit comparator COML, the pressure control signal SPCp_PCp start indicating the start of the operation of the first pressure pump PCp, and the pressure control signal SPCs_PCs start indicating the start of the operation of the second pressure pump PCs. And an AND gate D for outputting a logical AND operation.

The first pressure pump PCp and the second pressure pump PCs may share the total pressure capacity by 50%. When the pressure sensed by the pressure sensor PSa (or PSb, PSc, PSd) is lower than the lower pressure limit L, the logic circuit CONTROLLER of FIG. 4 firstly instructs the operation of the first pressure pump PCp. Outputs (SPCp_PCp run). If the pressure sensed by the pressure sensor PSa is lower than the lower pressure limit L even after 30 seconds have elapsed since the operation of the first pressure pump PCp starts, the logic circuit CONTROLLER of FIG. 4 controls the second through the AND gate B. The pressure control signal SPCs_PCs run instructing the operation of the pressure pump PCs is output. If both the first pressure pump PCp and the second pressure pump PCs are in operation but still the pressure sensed by the pressure sensor PSa is lower than the lower pressure limit L, the logic circuit CONTROLLER of FIG. Output a failure warning signal (fail) through D. On the other hand, when the pressure sensed by the pressure sensor PSa becomes higher than the upper pressure limit value H as both the first pressure pump PCp and the second pressure pump PCs are operated, the logic circuit CONTROLLER of FIG. The pressure control signal SPCs_PCs stop indicating the shutdown of the second pressure pump PCs is output through the AND gate C. When the pressure sensed by the pressure sensor PSa becomes higher than the upper pressure limit value H even when only the first pressure pump PCp is in operation, the logic circuit CONTROLLER of FIG. 4 passes through the AND gate A to the first pressure pump PCp. Outputs a pressure control signal (SPCp_PCp stop) indicating the stop of operation.

As the beverage consumption in the tables TAB1 to TAB5 varies, the pressure sensed by the pressure sensor PSa (or PSb, PSc, PSd) varies, and the pressure is applied in the above manner to reflect such a change in pressure. When the operation of the pumps PCp and PCs is controlled, the first pressure pump PCp and the second pressure pump PCs interlock to share the total pressure capacity by 50%. Therefore, the above method is advantageous in terms of energy efficiency compared to the method of applying a pressure capacity of 100% to one pressure pump at all times, thereby reducing the system operating cost.

On the other hand, the check valves (CVp and CVs in FIG. 2) provided in the pipes related to the pressure pump parts PCp and PCs are connected with the first pressure pump PCp and the second pressure pump PCs to operate the beverage. To prevent flow in the reverse direction. The equalization valve (UFV in FIG. 2) inserted into the main circulation pipe prevents the pressure in the main circulation pipe from changing rapidly. In addition, a safety valve (SFV in FIG. 2) inserted into the main circulation pipe radiates a part of the excessive pressure to the outside when the pressure in the main circulation pipe becomes excessively high.

In FIGS. 2 and 3A, the temperature controllers TCp and TCs cool or heat the beverage circulated along the main circulation pipe in response to the temperature control signals STCp and STCs. In the case of a beverage supply system for supplying a cooling beverage (coldly served beverages such as shochu), the temperature control unit is equipped with one or more coolers to ensure the required cooling capacity corresponding to the total number of tables and the total length of the main circulation pipe. And in the case of a beverage supply system for supplying heated beverages (drinks served hot, such as broth), the temperature control unit has at least one heater to ensure the required heating capacity corresponding to the total number of tables and the total length of the main circulation pipe. Equipped with. The temperature control in FIG. 2 has two coolers TCp and TCs (or two heaters TCp and TCs). The central controller controls the coolers TCp and TCs (or heaters TCp and TCs) through the temperature control signals STCp and STCs based on temperature sensing data from the temperature sensors TSa to TSd connected to the main circulation pipe. )] Controls each operation.

FIG. 5A illustrates the logic circuit CONTROLLER of the central control unit for controlling the operation of the coolers TCp and TCs when the temperature controller shown in FIG. 2 has two coolers TCp and TCs. .

The logic circuit CONTROLLER of FIG. 5A uses an output signal of an averager AVG and an averager AVG that averages the temperature sensing data from the temperature sensor TSa and the temperature sensing data from the temperature sensor TSd (or TSb). Temperature control signal for instructing the operation start of the upper limit comparator COMH and the first cooler TCp to compare the output signals of the lower limit comparator COML and the averager AVG to be compared with the temperature limit L. A delay (DEL) for delaying (STCp_TCp start) by 5 minutes and outputting, an AND gate (A) for performing logical AND operation on the output signal of the lower limit comparator (COML) and the output signal of the delay (DEL), and the upper limit comparator AND gate B for performing a logical AND operation on the output signal of COMH and the output signal of the delayer DEL, and outputting the output signal of the lower limit comparator COML and starting operation of the first cooler TCp. Temperature indicating the start of operation of the temperature control signal STCp_TCp and the second cooler TCs AND gate C for performing a logical AND operation on the control signal STCs_TCs start, and an output signal of the upper limit comparator COMH and a temperature control signal STCp_TCp start for instructing to start the operation of the first cooler TCp. The AND gate D which performs a logical AND operation on the temperature control signal STCs_TCs start for instructing the start of the operation of the two coolers TCs is provided.

In a beverage supply system for supplying a cold beverage (cold drink such as shochu), the logic circuit CONTROLLER configured as shown in FIG. 5A uses a predetermined temperature range (H to L) for the temperature of the beverage circulated along the main circulation pipe. Plays a role to keep me cool. The logic circuit CONTROLLER of FIG. 5A includes a temperature control signal STCp_TCp run for instructing the operation of the first cooler TCp as the average temperature sensed by the temperature sensors TSa, TSb, and TSd changes, and a second operation. Temperature control signal STCs_TCs run for instructing the operation of cooler TCs, failure warning signal fail, temperature control signal STCs_TCs stop for instructing operation of second cooler TCs or first cooler TCp. The temperature control signal (STCp_TCp stop) instructing to stop the operation is output, and thus, the first cooler TCp and the second cooler TCs may share the total cooling capacity by 50%. Similar to the case of FIG. 4, the method of controlling the operation of the two coolers TCp and TCs as shown in FIG. 5A is advantageous in terms of energy efficiency compared to the method of charging 100% of the cooling capacity at all times in one cooler. As a result, system operation costs can be reduced.

FIG. 5B illustrates a logic circuit CONTROLLER of the central control unit for controlling the operation of the heaters TCp and TCs when the temperature controller shown in FIG. 2 has two heaters TCp and TCs. .

In a beverage supply system for supplying heated beverages (drinks provided hot, such as broth), a logic circuit configured as shown in FIG. 5B uses a predetermined temperature range (L to H) for the temperature of the beverage circulated along the main circulation pipe. ) Plays a role to keep hot within. Similar to the case of FIG. 5A, the logic circuit CONTROLLER of FIG. 5B includes an averager AVG, an upper limit comparator COMH, a lower limit comparator COML, a delay DEL, an AND gate A, and an AND gate B. ), An AND gate (C), and an AND gate (D). However, the position of the upper limit comparator COMH and the position of the lower limit comparator COML differ from each other in the case of FIG. 5A. Those skilled in the art will appreciate that based on the description of FIG. 4 and the description of FIG. 5A, the logic circuit CONTROLLER of FIG. 5B starts the temperature sensing data from the temperature sensors TSa, TSd or TSb, starting the first heater TCp. The temperature control signal STCp_TCp start indicating the operation of the first heater TCp is input by receiving the temperature control signal STCp_TCp start indicating the operation and the temperature control signal STCs_TCs start indicating the start of the operation of the second heater TCs. ), A temperature control signal (STCs_TCs run) for instructing the operation of the second heater (TCs), a failure warning signal (fail), a temperature control signal (STCs_TCs stop) for instructing to stop the operation of the second heater (TCs) or the first It will be fully understood that a temperature control signal (STCp_TCp stop) is output to instruct the heater TCp to shut down.

After maintenance work is required or after closing of the restaurant, the beverage supply system of FIG. 2 may operate in the recovery operation mode shown in FIG. 3B. As shown in FIG. 3B, in the recovery operation mode, the main circulation pipe includes a pipe related to the pressure pump parts PCp and PCs, a cleaning pipe related to the cleaning liquid supply parts DST, and WTR, and a bypass valve BPV. The bypass pipe is closed, and the piping for the compressed air related to the air compressor parts AC and AR and the pipe not related to the pressure pump parts PCp and PCs are opened in the main circulation pipe. The air compressors (AC, AR) having an air compressor (AC in FIG. 2) for supplying compressed air and an air regulator (AR: air regulator in FIG. 2) for adjusting the amount of compressed air are operated in the recovery operation mode. Compressed air is introduced into the main circulation pipe so that the beverage remaining in the circulation pipe is recovered to the beverage storage tank (BST). Specifically, when the automatic valves AV1 and AV2 are opened by the central control unit, compressed air from the air compressor AC passes through the air volume regulator AR and flows into the main circulation pipe, and the beverage remaining in the main circulation pipe is compressed air. Is recovered to the beverage storage tank BST via the temperature controller TCp and TCs.

In the beverage supply system according to the preferred embodiment of the present invention, since the beverage remaining in the main circulation pipe can be effectively recovered using compressed air, the beverage remaining in the pipe after maintenance work or after closing of the restaurant is closed. The problem of discarding can be solved. Although the restaurant area is large and the total length of the main circulation pipe is quite long, compressed air can be used to effectively recover the remaining beverages in the main circulation pipe.

When it is necessary to clean the main circulation pipe or the like, the beverage supply system of FIG. 2 may operate in the cleaning operation mode shown in FIGS. 3C and 3D. In the cleaning operation mode as shown in FIG. 3C, the inlet valve (ILV in FIG. 2) and the outlet valve (OLV in FIG. 2) are closed, and the bypass valve (BPV in FIG. 2) is opened. The cleaning liquid supply units DST and WTR having a cleaning storage tank DST for storing the cleaning agent and a cleaning water supply WTR for supplying the cleaning water are used to clean the main circulation pipe and the like in the cleaning operation mode. Washing water, or a mixture of the cleaning agent and the washing water] is introduced into the main circulation pipe through the automatic valves EVa and EVb. As shown in FIG. 3C, the cleaning solution flowing from the cleaning solution providing units DST and WTR circulates through the main circulation pipe and the bypass pipe to wash away the waste in the pipe. In the cleaning operation mode, the inflow valve (ILV in FIG. 2) and the outflow valve are provided such that the cleaning liquid flowing from the cleaning liquid providing units DST and WTR passes the bypass pipe after bypassing the beverage storage tank BST after passing through the main circulation pipe. The OLV in FIG. 2 is closed and the bypass valve (BPV in FIG. 2) is opened.

Meanwhile, the cleaning liquid circulating in the main circulation pipe and the bypass pipe and cleaning the pipe may be discharged out through the drain pipes having the drain valves (DVa to DVc in FIG. 2) as shown in FIG. 3D. In addition, the cleaning liquid for cleaning the pipe may be discharged to the tables (TAB1 ~ TAB5) as shown in Figure 3d. The central controller may control the opening and closing of the drain valves DVa to DVc, the maintenance automatic valves SV1 to SV5, and the table automatic valves BV1 to BV5 to designate a discharge path of the cleaning liquid. For example, when the maintenance automatic valve SV4 is closed and the table automatic valve BV4 and the table manual valve MV4 are opened, the cleaning liquid which cleans the piping is discharged to the table TAB4 side.

As described above, according to the beverage supply system according to the preferred embodiment of the present invention, the cleaning liquid is introduced into the main circulation pipe and the introduced cleaning liquid is circulated along the main circulation pipe and the bypass pipe so that the pipe can be easily cleaned, and the valve By controlling the opening and closing of these, it is possible to specify the discharge path of the cleaning liquid. The cleaning operation of the pipes can be easily performed, so that the beverage supply system can be operated in a clean sanitary environment.

In the above described the present invention with reference to the specific embodiment shown in the drawings, but this is merely illustrative.
