Description

  The present invention relates to a frozen dessert manufacturing apparatus that manufactures a semi-solid frozen dessert represented by soft cream and shakes, and particularly relates to a frozen dessert manufacturing apparatus in which a plurality of pairs of tanks and cylinders are housed in one casing.

  In response to a request from a user to produce a plurality of types of frozen confectionery using a single frozen confectionery manufacturing apparatus, there has conventionally been a frozen confectionery manufacturing apparatus having two pairs of a mix tank and a cylinder.

  FIG. 10 shows a configuration of a conventional frozen dessert manufacturing apparatus 500. The frozen dessert manufacturing apparatus 500 includes a unit 510, a unit 520, a control unit 530, and an operation / display unit 540. The unit 510 has a mix tank 511, a cylinder 512, and a compressor 513, and the unit 520 has a mix tank 521, a cylinder 522, and a compressor 523.

  For example, in the unit 510, the mix that is the raw material for the frozen dessert is stored in the mix tank 511, and the mix is supplied from the mix tank 511 to the cylinder 512. In the cylinder 512, the mix is stirred and cooled, and the frozen dessert is taken out from the take-out port. The compressor 513 adjusts the cooling temperature of the cylinder 512 and the heating temperature during heat sterilization. The unit 520 is substantially the same as the unit 510. Furthermore, the control unit 530 controls the units 510 and 520 by the operation of the user of the frozen confectionery manufacturing apparatus 500 on the operation / display unit 540.

  In the mix tank 511 and the mix tank 521, raw materials having different tastes are stored. Thereby, a plurality of types of frozen desserts (for example, vanilla-flavored and strawberry-flavored) can be manufactured from one frozen dessert manufacturing apparatus 500. Moreover, it can also comprise so that soft cream may be provided from one of the mix tank 511 and the mix tank 521, and frozen confections other than soft creams, such as a shake, may be provided from the other.

  Moreover, the frozen confectionery manufacturing apparatus 500 is used in a place where two power distribution systems are installed. The rated power consumption of the compressor 513 and the compressor 523 is equal to each other, for example, 900 W. The compressor 513 is supplied with electric power from the power distribution system 601, and the compressor 523 is supplied with electric power from the power distribution system 602. Furthermore, the power distribution systems 601 and 602 are respectively provided with external breakers 611 and 612. For example, the external breakers 611 and 612 are supplied with a maximum of 1500 W, respectively.

  However, the conventional configuration uses an unnecessarily high-cooling capacity compressor for the following reasons. Since a large and expensive compressor is used because of its high cooling capacity, there are problems that the frozen dessert manufacturing apparatus itself becomes unnecessarily large and the manufacturing cost is high.

  Usually, the preference of a frozen dessert purchaser is not uniform with respect to the frozen desserts having different tastes. Therefore, when a plurality of types of frozen desserts are provided, the demand varies depending on the type of the frozen dessert. Therefore, in the frozen confectionery manufacturing apparatus 500, the amount of the frozen confection taken out from the cylinder 512 and the frozen confection taken out from the cylinder 522 may differ.

  For example, if the unit 510 provides a vanilla-flavored frozen dessert and the unit 520 provides a strawberry-flavored frozen dessert that is less in demand than the vanilla-flavored frozen dessert, the amount of mix supplied to the cylinder 512 per unit time is , More than the amount of mix supplied to the cylinder 522. Since the temperature of the mix supplied to the cylinder is higher than that of the frozen dessert that has already been cooled in the cylinder, the internal temperature of the cylinder 512 is likely to increase compared to the cylinder 522. In the frozen confectionery manufacturing apparatus 500, both the compressors 513 and 523 are configured to have a cooling capacity capable of cooling the raw material of the frozen confection supplied to the cylinder 512 of the unit 510 to a desired temperature within a desired time.

  However, since the amount of the frozen dessert material supplied to the cylinder 522 is smaller than the amount of the frozen dessert material supplied to the cylinder 512, the compressor 523 has a cooling capacity that exceeds the required cooling capacity. It will be. That is, the compressor 523 becomes unnecessarily large due to unnecessary high cooling capacity, and the frozen dessert manufacturing apparatus 500 itself becomes large, resulting in a high product cost.

  The present invention has been made in view of the above-described problems, and its purpose is to reduce the manufacturing cost of the frozen confectionery manufacturing apparatus, suppress the enlargement of the apparatus, and improve the efficiency according to the amount of the frozen confectionery provided. It is to realize a frozen confectionery manufacturing apparatus capable of adjusting the temperature.

  In order to solve the above problems, a frozen confection producing apparatus according to the present invention includes a container for storing a frozen confectionery raw material, a cylinder for producing the frozen confectionery by stirring and cooling the frozen confectionery raw material supplied from the container, and the cylinder And a temperature control device for adjusting the temperature of each of the frozen desserts, each of which is supplied from a first container and a second container for storing the raw material of the frozen dessert, and the first container and the second container, respectively. The first and second cylinders for producing frozen confectionery by stirring and cooling the raw material of the frozen confectionery, the first temperature adjusting device for adjusting the cooling temperature of the first container and the first cylinder, the second container and the second cylinder A second temperature control device that adjusts the cooling temperature of the two cylinders, and the cooling capacity of the first temperature control device is set higher than the cooling capacity of the second temperature control device. It is characterized in that.

  According to said structure, the cooling capacity of the said 1st temperature control apparatus is set higher than the cooling capacity of the said 2nd temperature control apparatus. For this reason, among the frozen desserts supplied from the first cylinder and the second cylinder, the frozen dessert with the larger supply amount (for example, the frozen dessert with vanilla flavor) is provided from the first cylinder, and the frozen dessert with the smaller provision amount ( For example, if the strawberry-flavored frozen dessert is provided from the second cylinder, the raw material of the frozen dessert with a large supply amount is stably cooled to a desired cooling temperature by the first temperature control device having a high cooling capacity. Can do. On the other hand, while reducing the manufacturing cost of the frozen confectionery manufacturing device by using the cooling target of the demand for the second temperature adjusting device, which has a lower cooling capacity and lower cost than the first temperature adjusting device, as the raw material for the frozen confectionery with a small amount of provision. Thus, an unnecessary size increase of the apparatus can be suppressed, and a frozen confection manufacturing apparatus capable of efficiently adjusting the temperature according to the amount of frozen confection can be realized.

  In the frozen confectionery manufacturing apparatus according to the present invention, the capacity of the first container is preferably larger than the capacity of the second container.

  According to said structure, the capacity | capacitance of the 1st container which stores the raw material of the cold confectionery of the 1st temperature control apparatus whose cooling capacity is higher than a 2nd temperature control apparatus is used as the cooling confectionery of the 2nd temperature control apparatus. The capacity of the second container for storing the raw material is larger. For this reason, when the frozen confection with the larger amount of supply (for example, vanilla-flavored frozen confectionery) is put in the second container, the material of the frozen confection must be replenished frequently, but it is stored in the first container with a large capacity. By doing so, the number of times the frozen confectionery material is replenished to the first container can be reduced, and the replenishment work can be reduced.

  In the frozen confectionery manufacturing apparatus according to the present invention, the capacity of the first cylinder is preferably larger than the capacity of the second cylinder.

  According to said structure, a 1st cylinder can store a lot of frozen desserts than a 2nd cylinder. The amount of frozen dessert that can be continuously taken out is determined mainly by the capacity of the cylinder, so that the first cylinder can take out more frozen dessert continuously than the second cylinder, and a large amount of frozen dessert needs to be taken out in a short time. Can be easily handled.

  In the frozen dessert manufacturing apparatus according to the present invention, a first power cable for supplying power from the first power distribution system to the first temperature control device and power supply from the second power distribution system to the second temperature control device are further provided. The second power cable is provided with first overcurrent protection means, and the maximum allowable current in the first overcurrent protection means flows through the first power cable. It is preferable to set the current smaller than the current.

  Since the cooling capacity of the second temperature control device is lower than the cooling capacity of the first temperature control device, the rated power consumption of the second temperature control device is lower than the rated power consumption of the first temperature control device. In order to avoid the occurrence of problems such as overheating if the first temperature control device fails and the current flowing through the first power cable becomes excessive and if left unattended, the first power cable is generally connected to the outside of the frozen confectionery manufacturing device. Is connected to the overcurrent protection means installed in the, and current is supplied from the overcurrent protection means. That is, when the current passing through the overcurrent protection unit exceeds a predetermined current due to the failure, the overcurrent protection unit cuts off the power supply and stops the first temperature control device and the like. On the other hand, the overcurrent value due to the failure in the second temperature control device is lower than that in the first temperature control device. For this reason, if the same overcurrent protection means as that of the first power supply cable is connected to the second power supply cable, even if an overcurrent flows through the second power supply cable, the current value is low. The means does not cut off the energization, and there is a risk of causing an accident due to overheating of the second temperature control device. However, according to the above configuration, since the first power supply cable is provided with the first overcurrent protection means, the first overcurrent protection means cuts off the energization current due to the excessive current flowing through the second temperature control device. Thereby, the risk that the second temperature controller is overheated due to overcurrent can be reduced.

  The frozen dessert manufacturing apparatus according to the present invention further includes a third container for storing frozen confectionery raw materials, a third cylinder for producing frozen confectionery by stirring and cooling the frozen confectionery raw materials supplied from the third container, And a third temperature adjusting device for adjusting the cooling temperature of the three containers and the third cylinder, wherein the cooling capacity of the first temperature adjusting device is set higher than the cooling capacity of the third temperature adjusting device. Also good.

  According to said structure, the cooling capacity of the said 1st temperature control apparatus is set higher than the cooling capacity of the said 3rd temperature control apparatus. For this reason, among the frozen desserts supplied from the first cylinder and the third cylinder, the frozen dessert with the larger supply amount (for example, vanilla-flavored frozen dessert) is provided from the first cylinder, and the frozen dessert with the smaller provision amount ( For example, if the third flavor of chocolate-flavored frozen dessert is provided from the third cylinder, the raw material of frozen dessert with a large supply amount is stably cooled to a desired cooling temperature by the first temperature control device having a high cooling capacity. Can do. On the other hand, by making the cooling target of the third temperature control device, which has a lower cooling capacity and lower cost than the first temperature control device, as the raw material of the frozen dessert with a small amount of provision, An unnecessary size increase of the apparatus can be suppressed, and a frozen dessert manufacturing apparatus capable of efficiently adjusting the temperature according to the amount of frozen dessert provided can be realized.

  In the frozen confectionery manufacturing apparatus according to the present invention, the capacity of the first container is preferably larger than the capacity of the third container.

  According to said structure, the capacity | capacitance of the 1st container which stores the raw material of the cold confectionery of the 1st temperature control apparatus whose cooling capacity is higher than a 3rd temperature control apparatus is set as the cold confectionery of the 3rd temperature control apparatus. It is larger than the capacity of the third container for storing the raw material. For this reason, when the frozen confection with the larger amount of supply (for example, vanilla-flavored frozen confectionery) is put in the second container, the material of the frozen confection must be replenished frequently, but it is stored in the first container with a large capacity. By doing so, the number of times the frozen confectionery material is replenished to the first container can be reduced, and the replenishment work can be reduced.

  In the frozen dessert manufacturing apparatus according to the present invention, the capacity of the first cylinder is preferably larger than the capacity of the third cylinder.

  According to the above configuration, the first cylinder can store a larger amount of frozen dessert than the third cylinder. The amount of frozen confectionery that can be taken out continuously is mainly determined by the capacity of the cylinder, so that the first cylinder can continuously take out more frozen confectionery than the third cylinder, and it is necessary to take out a large amount of frozen confectionery in a short time. Can be easily handled.

  In the frozen confectionery manufacturing apparatus according to the present invention, the first cylinder is preferably provided so as to be adjacent to the two cylinders.

  Here, generally, when providing mixed frozen confectionery from two cylinders, frozen confectionery (for example, vanilla) with higher demand than frozen confectionery (for example, strawberry flavor and chocolate flavor mixed) with less demanded confectionery. There is more demand for mixed frozen desserts containing flavored ones. According to said structure, when a frozen dessert manufacturing apparatus has three cylinders, for example, a 1st cylinder is provided so that it may adjoin a 2nd cylinder and a 3rd cylinder. Thus, when mixing the frozen desserts in the adjacent cylinders, the frozen dessert in the first cylinder and the frozen dessert in the second cylinder, the frozen dessert in the first cylinder and the third cylinder, The mixed frozen confectionery can be taken out. Furthermore, since the cooling capacity of the first temperature control device is set higher than the cooling capacity of the third temperature control device, if it is configured so that frozen dessert with much demand is taken out from the first cylinder, as described above. In addition, it is possible to realize a frozen dessert manufacturing apparatus capable of efficiently adjusting the temperature according to the amount of frozen dessert provided, and to provide a mixed frozen dessert that meets the demand from the frozen dessert manufacturing apparatus.

  In the frozen dessert manufacturing apparatus according to the present invention, the second power supply via the first power supply cable for supplying power from the first power distribution system to the first temperature control device, and the second power supply system via the shared power cable. It is preferable to include a second power cable and a third power cable for supplying power to the temperature control device and the third temperature control device, respectively.

  According to said structure, the said 2nd temperature control apparatus and said 3rd temperature control apparatus with small cooling capability compared with the said 1st temperature control apparatus share a power supply. For this reason, the power supply environment of the two power distribution systems used for the frozen dessert manufacturing apparatus provided with two cylinders can be applied to the frozen dessert manufacturing apparatus provided with three cylinders. For this reason, the power distribution system of the frozen confectionery manufacturing apparatus provided with the three cylinders can be realized without requiring a large facility change from the power supply environment of the existing two power distribution systems.

  In the above configuration, the second power cable and the third power cable are provided with second overcurrent protection means and third overcurrent protection means, respectively. It is preferable that each maximum allowable current in the overcurrent protection means is set smaller than the maximum current flowing through the first power cable.

  Since the cooling capacity of the second temperature control device and the third temperature control device is lower than that of the first temperature control device, the rated power consumption of the second temperature control device and the third temperature control device is the first temperature control device. Lower than the rated power consumption. In order to avoid the occurrence of problems such as overheating if the first temperature control device fails and the current flowing through the first power cable becomes excessive and if left unattended, the first power cable is generally connected to the outside of the frozen confectionery manufacturing device. Is connected to the overcurrent protection means installed in the, and current is supplied from the overcurrent protection means. That is, when the current passing through the overcurrent protection unit exceeds a predetermined current due to the failure, the overcurrent protection unit cuts off the power supply and stops the first temperature control device and the like. On the other hand, the overcurrent value due to failure in the second temperature control device and the third temperature control device is lower than that in the case of the first temperature control device. For this reason, if the same overcurrent protection means as that for the first power cable is connected to the second power cable or the third power cable, even if an overcurrent flows to the second power cable or the third power cable, Since the current value is low, the overcurrent protection means does not cut off the current supply, which may cause an accident due to overheating of the second or third temperature control device. However, according to the above configuration, the second overcurrent protection unit and the third overcurrent protection unit are provided in the second power supply cable and the third power supply cable. The second or third overcurrent protection means cuts off the energization current due to the flowing excessive current. Thereby, the risk that the second temperature adjusting device and the third temperature adjusting device may overheat due to overcurrent can be reduced.

  The frozen dessert manufacturing apparatus according to the present invention further includes control means for controlling each of the temperature control devices, and the temperature control devices adjust the heating temperature of the cylinders when the cylinders are sterilized by heating. The control means controls the temperature adjustments so that when the cylinders are sterilized by heating, all of the cylinders are simultaneously kept at a predetermined temperature or higher for a predetermined time. It is preferable to control the apparatus.

  According to said structure, even if it is a case where the frozen confection manufacturing apparatus is provided with the extraction port which mixes and takes out the raw material of each frozen confectionery in an adjacent cylinder, all the cylinders are predetermined in heat sterilization operation. Therefore, the outlet that receives the supply of the frozen dessert material heated from the cylinder can be heated to a sufficient sterilization temperature. Therefore, when the cylinder is sterilized by heating, the outlet can be sterilized reliably.

  In the frozen confectionery manufacturing apparatus according to the present invention, when the control means heat sterilizes the cylinders, time measuring means for measuring the elapsed time from the start of heating, and when the elapsed time reaches a predetermined time. A temperature comparing means for comparing each temperature of each cylinder with the predetermined temperature; and a temperature for adjusting the heating temperature of the cylinder when at least one heating temperature of each cylinder is less than the predetermined temperature. It is preferable to include a determination unit that determines that the adjusting device is out of order.

  According to said structure, the temperature control apparatus which requires the time for heating a cylinder to sterilization temperature more than predetermined time is detectable. Therefore, it can be determined whether or not the frozen dessert manufacturing apparatus has any hindrance to normal use.

  In the frozen confectionery manufacturing apparatus according to the present invention, it is preferable that the temperature adjusting device is configured to heat sterilize the containers when the cylinders are heat sterilized.

  According to said structure, since the raw material in a container is also heat-sterilized, a more hygienic frozen dessert manufacturing apparatus is realizable.

  According to the frozen confectionery manufacturing apparatus according to the present invention, while reducing the manufacturing cost of the frozen confectionery manufacturing apparatus, an unnecessary increase in the size of the apparatus can be suppressed, and the temperature can be efficiently adjusted according to the amount of the frozen confectionery provided. There is an effect that can be realized.

[Embodiment 1]
An embodiment of the present invention will be described below with reference to FIGS.

  FIG. 1 is a block diagram showing a configuration of a frozen dessert manufacturing apparatus 100 according to the present embodiment. The frozen dessert manufacturing apparatus 100 includes units 101 and 102, a control unit 110, an operation / display unit 120, and a breaker 130. The unit 101 has a mix tank 1a, a cylinder 2a, and a compressor 3a, and the unit 102 has a mix tank 1b, a cylinder 2b, and a compressor 3b. The control unit 110 controls the units 101 and 102 by the operation of the user of the frozen confectionery manufacturing apparatus 100 on the operation / display unit 120.

  The unit 101 provides, for example, a vanilla-flavored frozen dessert, and the unit 102 provides, for example, a strawberry-flavored frozen dessert. In general, vanilla-flavored frozen desserts are more demanding than strawberry-flavored frozen desserts, so there are more frozen desserts provided from unit 101 than frozen desserts provided from unit 102.

  FIG. 2 is a circuit diagram showing a detailed configuration of the unit 101 shown in FIG. The unit 101 is provided with a mix tank 1a, a cylinder 2a, and a compressor 3a. The mix tank 1a cools and stores the mix that is the raw material of the frozen dessert. The cylinder 2a is connected to the mix tank 1a via the spout 15 and cools the kneaded mix supplied from the mix tank 1a to produce a frozen dessert. The compressor 3a cools the mix tank 1a and the cylinder 2a and heats them for sterilization. High-temperature and high-pressure gas refrigerant is discharged from the compressor 3a, and heat exchange is performed between the gas refrigerant and the mix tank 1a and the cylinder 2a through a path described later.

  An impeller 16 for stirring the mix is provided in the mix tank 1a, and the impeller 16 is rotated by a tank stirring motor 17 provided in the vicinity of the mix tank 1a. A duster motor 26 for stirring the inside of the cylinder 2a is provided in the vicinity of the cylinder 2a. ON / OFF control of the tank agitation motor 17 and the duster motor 26 is performed by the control unit 110 based on the user's operation in the operation / display unit 120 and the conditions such as the temperature in the cylinder 2a. Furthermore, five solenoid valves, a first solenoid valve SV1 to a fifth solenoid valve SV5, are provided in the refrigerant circuit connecting the mix tank 1a, the cylinder 2a, and the compressor 3a.

  Further, although not shown, the temperature sensor is provided in the mix tank 1a, the cylinder 2a, and the spout 15, and the temperature in the mix tank 1a and the cylinder 2a is shown in FIG. Displayed on the operation / display unit 120 shown.

  FIG. 3 is a circuit diagram showing a detailed configuration of the unit 102 shown in FIG. The unit 102 is provided with a mix tank 1b, a cylinder 2b, and a compressor 3b. The configuration of the unit 102 is the same as that of the unit 101 shown in FIG. 2 in which the mix tank 1a, cylinder 2a, and compressor 3a are replaced with the mix tank 1b, cylinder 2b, and compressor 3b, respectively. Further, the use / function of each member of the unit 102 is the same as that of each member of the unit 101, and therefore detailed description of the unit 102 is omitted.

  Thus, in the frozen dessert manufacturing apparatus 100 having a plurality of cylinders 2a and 2b, the amount of heat required for cooling the cylinders 2a and 2b is different from each other. Therefore, a compressor which is an independent cooling means for each cylinder 2a and 2b. 3a and 3b are provided, respectively.

  Here, the unit 101 and the unit 102 are compared as follows. First, the rated power consumption of the compressor 3a is higher than the rated power consumption of the compressor 3b. As a result, the cooling capacity of the compressor 3a is set higher than the cooling capacity of the compressor 3b. Thereby, the mix tank 1a in which the internal temperature is more likely to rise than the mix tank 1b can be kept at a low temperature.

  In addition, what is necessary is just to set the cooling capacity of the compressor 3a and the compressor 3b according to the quantity of the frozen dessert provided from the unit 101 and the unit 102. FIG. For example, it is assumed that a maximum of about 20 frozen desserts per 5 minutes are provided per unit of soft ice from unit 101 to 140 cc, and a maximum of about 15 frozen desserts are provided per unit of water from 140 units of 140 cc. The rated power consumption of the compressor 3a is set to about 1100W, and the rated power consumption of the compressor 3b is set to about 750W.

  In this way, by setting the cooling capacity of the compressors 3a and 3b according to the amount of frozen confectionery provided, the size of the frozen confectionery manufacturing apparatus 100 can be suppressed, and the product cost of the frozen confectionery manufacturing apparatus 100 itself can be suppressed. Note that the greater the rated power consumption of the compressor, the higher the cooling capacity of the compressor.

  Moreover, what is necessary is just to set the capacity | capacitance of the mix tank 1a and the mix tank 1b according to the quantity of the frozen dessert provided from the unit 101 and the unit 102. FIG. In the present embodiment, the capacity of the mix tank 1a is larger than the capacity of the mix tank 1b. Thereby, the number of mix replenishments in the mix tank 1a in which the amount of mix to be replenished is larger than that of the mix tank 1b can be reduced.

  Further, in the cylinders 2a and 2b, the capacity of the cylinder 2a is configured to be larger than the capacity of the cylinder 2b, whereby the cylinder 2a can store a larger amount of frozen dessert than the cylinder 2b. Therefore, the cylinder 2a can continuously take out more frozen desserts than the cylinder 2b.

  Then, with reference to FIG. 1, the breaker 130 provided in the frozen dessert manufacturing apparatus 100 is demonstrated. The frozen dessert manufacturing apparatus 100 is supplied with power from the two distribution systems 601 and 602 provided at the installation site, and the power cable 141 and the power cable 142 are connected to the distribution system 601 and the distribution system 602, respectively. ing. Here, the power consumed by the unit 101 is supplied by the power cable 141, and the power consumed by the unit 102 is supplied by the power cable 142.

  The power distribution system 601 and the power distribution system 602 are provided with an external breaker 611 and an external breaker 612, respectively. The external breakers 611 and 612 are overcurrent protection devices for cutting off the power supply when the current flowing from the distribution systems 601 and 602 exceeds a predetermined rated current (maximum allowable current). The maximum allowable current in the external breaker 611 is larger than the current flowing through the power cable 141 when the unit 101 is in a normal state, and smaller than the overcurrent flowing through the power cable 141 due to a failure of the compressor 3a. For example, in the unit 101, when the consumption current rises due to the failure of the compressor 3a and the current flowing through the power cable 141 exceeds, for example, 20A, the power supply is cut off by the external breaker 611, and the temperature due to the overcurrent of the compressor 3a The ascent stops and accidents due to overheating are prevented.

  On the other hand, in the unit 102, the rated power consumption of the compressor 3b is smaller than that of the compressor 3a. Therefore, even if the current flowing through the unit 102 is less than or equal to the rated current of the external breaker 612, there is a risk of abnormal heat generation due to a failure of the compressor 3b. is there. Therefore, in the frozen dessert manufacturing apparatus 100, the breaker 130 is provided in the power distribution system 602. The breaker 130 cuts off the power supply from the power distribution system 602 to the unit 102 when a current exceeding a predetermined rated current flows through the power cable 142 due to a failure of the compressor 3b or the like. The maximum allowable current in the breaker 130 is set smaller than the maximum current that flows through the power cable 141 when the frozen dessert manufacturing apparatus 100 is abnormal. That is, the rated current of the breaker 130 is set to be lower than the rated current value of the external breakers 611 and 612 and higher than the normal consumption current of the unit 102, for example, 10A.

  Thus, when a current exceeding 10 A flows through the power cable 142 and there is a risk of abnormal heat generation or the like, safety is maintained by operating the breaker 130 even if the external breaker 612 does not operate. The breaker 130 may be provided inside the casing of the frozen dessert manufacturing apparatus 100 or may be provided outside the casing of the frozen dessert manufacturing apparatus 100. Further, instead of the breaker 130, a fuse may be provided as overcurrent protection means.

  Next, a specific configuration for cooling and heating the mix tank 1a and the cylinder 2a of the unit 101 will be described with reference to FIG. The inside of the cylinder 2a is normally kept at a low temperature at which bacteria and the like are difficult to grow. However, for food hygiene reasons, according to the ministerial ordinance concerning the component standards of milk and dairy products, at least once a day, It is necessary to perform heat sterilization. The heat sterilization is performed by heating the inside of the cylinder to a predetermined temperature (68 ° C.) or higher and maintaining it for a predetermined time (30 minutes) or longer. The function of cooling and heating the mix tank 1a and the cylinder 2a is realized as follows.

The tank heat exchanger 5 performs heat exchange between the mix tank 1a and the refrigerant, and the cylinder heat exchanger 6 performs heat exchange between the cylinder 2a and the refrigerant. The four-way valve 7 switches the flow direction of the discharge gas refrigerant from the compressor 3a.

  The four-way valve 7 is provided with an inflow port D, a relay port S, a first switching port C, and a second switching port E. A discharge pipe 8 of the compressor 3a is connected to the inflow port D. The relay port S is connected to a relay pipe 24 that communicates with the suction pipe 9 of the compressor 3a. A first gas pipe 10, a water condenser 11, and a liquid pipe 12 are sequentially connected to the first switching port C. Further, the distal end side of the liquid pipe 12 is branched into a first branch pipe 12a, a second branch pipe 12b, and a third branch pipe 12c through a dryer 25.

  The water condenser 11 is configured as a water heat exchanger. Inside the water condenser 11, a heat exchange refrigerant pipe 11 a and a water pipe 13 are arranged in parallel, and heat exchange is performed between the refrigerant flowing through the heat exchange refrigerant pipe 11 a and the cooling water flowing through the water pipe 13. Is called.

  A first check valve CV1 is provided in the first gas pipe 10, and the first check valve CV1 blocks the flow of refrigerant from the water condenser 11 side toward the first switching port C. A high cut switch 22 is provided between the compressor 3 a and the four-way valve 7. The high cut switch 22 detects the discharge gas pressure of the compressor 3a. When the pressure becomes too high, the high cut switch 22 sends a signal to the control unit 110. The control unit 110 stops the operation of the compressor 3a, and the pressure is excessive. To prevent becoming.

  A branch pipe 10a is provided between the first check valve CV1 and the heat exchange refrigerant pipe 11a, and the branch pipe 10a is connected to the water valve 13a. Thereby, when a certain pressure or more is applied to the first gas pipe 10, the valve of the water valve 13 a is opened and the cooling water flows into the water pipe 13.

  The first branch pipe 12a is provided with a first electromagnetic valve SV1 and a first capillary tube 20a. The first capillary tube 20a is connected to a portion between the tank heat exchanger 5 and the fifth electromagnetic valve SV5. The second branch pipe 12b is provided with a second solenoid valve SV2 and a second capillary tube 20b, and the second capillary tube 20b is connected to a cylinder suction pipe 9c communicating with the cylinder 2a. The third branch pipe 12c is provided with a third electromagnetic valve SV3 and a constant pressure expansion valve 21.

  Further, the suction pipe 9 is provided with an accumulator 23 for performing gas-liquid separation of the refrigerant. The refrigerant inflow side of the suction pipe 9 is branched into a second heat exchange pipe 9 d and a relay pipe 24. The second heat exchange pipe 9d is connected to the constant pressure expansion valve 21 through the auxiliary heat exchanger 14. The suction pipe 9a is connected to the tank heat exchanger 5 of the mix tank 1a. The relay pipe 24 is connected to the relay port S of the four-way valve 7.

  A suction pipe 9a is connected to the second switching port E of the four-way valve 7, and the suction pipe 9a is connected to the heat exchanger 6 for the cylinder of the mix tank 1a and the cylinder 2a.

  On the other hand, in the auxiliary heat exchanger 14, a second heat exchange pipe 9d and a first heat exchange pipe 14a are provided side by side, and heat exchange is performed between the refrigerants respectively flowing in the pipes 14a and 9d. Is called.

  One end of the first bypass pipe 31 and one end of the second bypass pipe 32 are connected to both ends of the first heat exchange pipe 14a, respectively. The other end of the first bypass pipe 31 is connected to the fourth solenoid valve SV4, and the fourth solenoid valve SV4 is connected to the cylinder heat exchanger 6 via the cylinder suction pipe 9c. The second bypass pipe 32 has a second check valve CV2, and the other end of the second bypass pipe 32 is connected to a portion between the first check valve CV1 and the water condenser 11. Yes. The second check valve CV2 blocks the refrigerant flow from the water condenser 11 side toward the auxiliary heat exchanger 14.

  In the above configuration, first, a cooling operation for cooling both the mix tank 1a and the cylinder 2a, that is, an operation during normal frozen dessert production will be described.

  First, in the four-way valve 7, switching is performed so that the inflow port D communicates with the first switching port C and the relay port S communicates with the second switching port E. Subsequently, the first electromagnetic valve SV1 and the second electromagnetic valve SV2 are opened, the third electromagnetic valve SV3, the fourth electromagnetic valve SV4, and the fifth electromagnetic valve SV5 are closed, and the compressor 3a is operated. As a result, the refrigerant circulates along the cooling and refrigeration circulation path indicated by the solid line arrow in FIG. 2, and the mix tank 1a and the cylinder 2a are cooled.

  In the cooling and refrigeration operation, about 100 ° C. high-temperature and high-pressure gas refrigerant discharged from the compressor 3 a is led to the water condenser 11 through the discharge pipe 8, the four-way valve 7 and the first gas pipe 10, and water is discharged by the water condenser 11. It condenses by heat exchange with the cooling water flowing through the pipe 13. The liquid refrigerant condensed here flows out into the liquid pipe 12 and is divided into the first branch pipe 12a and the second branch pipe 12b through the dryer 25.

  The diverted liquid refrigerant is depressurized when passing through the first capillary tube 20a and the second capillary tube 20b, and changes to a low-pressure liquid refrigerant. When the liquid refrigerant flows into the tank heat exchanger 5 and the cylinder heat exchanger 6 respectively, the liquid refrigerant is further depressurized, rapidly adiabatically expands, absorbs heat from the surroundings, and evaporates. Thereby, the mix tank 1a is cooled to about 0 to 4 ° C., and the cylinder 2a is frozen to about −2 to −7 ° C.

  The flow rate of the refrigerant passing through the first branch pipe 12a and the second branch pipe 12b is adjusted by opening / closing the first solenoid valve SV1 and the second solenoid valve SV2, thereby keeping the mix tank 1a at the cooling temperature and the cylinder. Temperature control is performed to bring 2a to the freezing temperature.

  The low-temperature and low-pressure gas refrigerant evaporated in the tank heat exchanger 5 and the cylinder heat exchanger 6 flows into the accumulator 23 through the suction pipe 9a, the relay pipe 24 and the suction pipe 9, and the liquid component is removed. It is returned to the compressor 3a.

  The gas refrigerant returned to the compressor 3a is pressurized again to become a high-temperature and high-pressure gas refrigerant, discharged to the water condenser 11, and circulates in the cooling circulation path.

  Next, a heating operation for heating the mix tank 1a and the cylinder 2a will be described.

  First, in the four-way valve 7, switching is performed so that the inflow port D communicates with the second switching port E and the relay port S communicates with the first switching port C. Note that the refrigerant does not flow to the relay port S and the first switching port C by the first check valve CV1. Subsequently, the third solenoid valve SV3, the fourth solenoid valve SV4, and the fifth solenoid valve SV5 are opened, the first solenoid valve SV1 and the second solenoid valve SV2 are closed, and the compressor 3a is operated. Thereby, a refrigerant | coolant circulates along the heating circulation path | route shown by (triangle | delta) arrow, and switches to heating operation.

  In the heating operation, about 100 ° C. high-temperature and high-pressure gas refrigerant discharged from the compressor 3 a passes through the discharge pipe 8, the four-way valve 7, and the suction pipe 9 a to the tank heat exchanger 5 and the cylinder heat exchanger 6. Inflow. Here, the gas refrigerant becomes a high-temperature and high-pressure gas refrigerant of about 70 to 80 ° C. after heating the mix tank 1a and the cylinder 2a by heat radiation to the surroundings.

  The gas refrigerant discharged from the mix tank 1a flows into the auxiliary heat exchanger 14 through the tank suction pipe 9b, the fifth electromagnetic valve SV5, and the first bypass pipe 31. Further, the gas refrigerant discharged from the cylinder 2a flows into the auxiliary heat exchanger 14 through the cylinder suction pipe 9c, the fourth electromagnetic valve SV4, and the first bypass pipe 31.

  In the auxiliary heat exchanger 14, the gas refrigerant is heat-exchanged with a low-temperature and low-pressure gas-liquid mixed refrigerant, which will be described later, and then flows into the water condenser 11 through the second bypass pipe 32 to condense, and is liquid at about 40 ° C. Becomes a refrigerant. Subsequently, the liquid refrigerant flows out to the liquid pipe 12 and flows into the third branch pipe 12c.

  The liquid refrigerant that has flowed into the third branch pipe 12c undergoes adiabatic expansion when passing through the constant pressure expansion valve 21, and changes to a low-temperature low-pressure gas-liquid mixed refrigerant. Thereafter, the gas-liquid mixed refrigerant flows into the auxiliary heat exchanger 14 through the second heat exchange pipe 9d, and evaporates by exchanging heat with the high-temperature gas refrigerant flowing through the first heat exchange pipe 14a. Thereafter, the evaporated gas refrigerant is returned to the compressor 3a through the suction pipe 9 and the accumulator 23, and is pressurized again in the compressor 3a to become a high-temperature and high-pressure gas refrigerant and circulates in the heating circulation path.

  As described above, the mix tank 1a and the cylinder 2a of the unit 101 are cooled and heated. Similarly, in the unit 102 shown in FIG. 3, the mix tank 1b and the cylinder 2b are cooled and heated.

  In the heating operation, the configuration may be such that only the cylinder 2a is heated while keeping the mix tank 1a at a low temperature. This configuration is disclosed in Japanese Patent No. 2869407 (Dec. 1998) related to the previous patent application by the present applicant. Month 25 registration). The cooling and heating method is not limited to the above method, and the cylinder and the mix tank may be heated with a heater or the like.

  FIG. 4 shows a part of the front of the frozen dessert manufacturing apparatus 100. Mix tanks 1a and 1b are provided at the top of the frozen dessert manufacturing apparatus 100, and cylinders 2a and 2b are attached to the front of the frozen dessert manufacturing apparatus 100. Lids 18a and 18b are attached to the mix tanks 1a and 1b. An outlet 27a is provided in front of the cylinder 2a, and an outlet 27c is provided in front of the cylinder 2b. The frozen dessert in the cylinder 2a is taken out from the outlet 27a, and the frozen dessert in the cylinder 2b is taken out from the outlet 27c.

  Further, an outlet 27b is provided between the outlet 27a and the outlet 27c. The outlet 27a and the outlet 27b are connected by a pipe 28a, and the outlet 27b and the outlet 27c are connected by a pipe 28b. Thereby, the frozen dessert which mixed the frozen dessert in the cylinder 2a and the frozen dessert in the cylinder 2b is taken out from the take-out port 27b.

  In addition, an operation / display unit 120 is provided above the outlets 27a to 27c, and the operation / display unit 120 is provided with a plurality of switches for the user to control the frozen confectionery manufacturing apparatus 100. Yes.

  Here, when the inside of the cylinder 2a and the cylinder 2b is sterilized by heating by the above-described heating operation, even if the compressor 3a and the compressor 3b shown in FIG. 1 start the operation at the same time, the degree of heating of the cylinder 2a and the cylinder 2b is different. There is. Specifically, when the heat capacities of the mix in the cylinder 2a and the mix in the cylinder 2b are different, or the heating capacity of the compressor 3a and the heating capacity of the compressor 3b are different, the cylinders 2a and 2b are moved from a low temperature state. The time taken to heat to the temperature required for sterilization varies.

  Here, the inside of the outlet 27a and the outlet 27c is heated and sterilized by heat transmitted from the cylinder 2a and the cylinder 2b through the mix, respectively. However, if the timings at which the insides of the cylinders 2a and 2b reach the temperature necessary for sterilization are different, there is a possibility that sufficient heat may not be transmitted to the inside of the outlet 27b.

  Therefore, in the frozen dessert manufacturing apparatus 100, the control unit 110 shown in FIG. 1 continues the state in which the temperature in the cylinder 2a and the temperature in the cylinder 2b are both equal to or higher than a predetermined temperature required for sterilization for a predetermined time. Thus, the compressors 3a and 3b are controlled. Hereinafter, the heat sterilization operation of the frozen confectionery manufacturing apparatus 100 will be described.

  FIG. 5 is a block diagram showing the configuration of the control unit 110 shown in FIG. The control unit 110 includes an operation switching unit 111, a time measurement unit 112, a temperature comparison unit 113, and a determination unit 114. The operation switching unit 111 performs valve opening / closing control of the first electromagnetic valve SV1 to the fifth electromagnetic valve SV5. The time measuring unit 112 measures an elapsed time from the start of the heating operation and an elapsed time after the cylinders 2a and 2b reach a predetermined sterilization temperature. The temperature comparison unit compares the temperature in the cylinders 2a and 2b with a predetermined sterilization temperature. A determination part determines the quality of the heating function of compressor 3a * 3b.

  FIG. 6 is a flowchart showing the procedure of the heating operation in the frozen confectionery manufacturing apparatus 100. When the operation switching unit 111 switches from the cooling / freezing operation to the heating operation and the heating operation is started (step S1), the temperature comparison unit 113 determines whether both the cylinders 2a and 2b have reached a predetermined sterilization temperature. Determine (step S2). When both of the cylinders 2a and 2b have reached the predetermined sterilization temperature ("YES" in step S2), the time measured by the time measuring unit 112 after both of the cylinders 2a and 2b have reached the predetermined sterilization temperature Is measured, and it is determined whether or not a predetermined time (for example, 30 minutes) has passed (step S3). When the predetermined time has elapsed (“YES” in step S3), the operation switching unit 111 switches from the heating operation to the cooling refrigeration operation, and causes the compressor 3a to start cooling the cylinders 2a and 2b.

  Moreover, the frozen dessert manufacturing apparatus 100 has a function of detecting a failure of the compressors 3a and 3b. Hereinafter, the detection function will be described with reference to FIGS. 1 and 7.

  FIG. 7 is a flowchart showing a failure detection procedure of the compressors 3a and 3b in the frozen confectionery manufacturing apparatus 100. When the operation switching unit 111 switches from the cooling / freezing operation to the heating operation and the heating operation is started (step S11), the time measuring unit 112 starts measuring the time elapsed from the start of heating the cylinders 2a and 2b. (Step S12). When a predetermined time has elapsed from the start of the measurement by the time measuring unit 112 (“YES” in step S13), the temperature comparison unit 113 changes the temperature in the cylinders 2a and 2b to a predetermined sterilization based on a signal from the temperature sensor. The temperature is compared (step S14). When the temperatures in the cylinders 2a and 2b are both equal to or higher than the predetermined sterilization temperature ("YES" in step S15), the determination unit 114 determines that the compressors 3a and 3b are normal (step S16).

  On the other hand, if at least one of the cylinders 2a and 2b has an internal temperature lower than the predetermined sterilization temperature ("NO" in step S15), the determination unit 114 must ensure that the temperature in the cylinder 2a does not reach the predetermined sterilization temperature. If it is determined that the compressor 3a is malfunctioning, and the temperature in the cylinder 2b is less than the predetermined sterilization temperature, it is determined that the compressor 3b is malfunctioning (step S17). In this case, the fact that the compressor 3a and / or the compressor 3b has failed is displayed on the operation / display unit 120 (step S18). Thereby, the user of the frozen confectionery manufacturing apparatus 100 can easily know the failure of the apparatus.

  Further, in the frozen dessert manufacturing apparatus 100, identification indications 19a and 19b are provided in the vicinity of the lids 18a and 18b, respectively. The identification indications 19a and 19b are indications for distinguishing between the mix tank 1a and the mix tank 1b. For example, the identification indication 19a indicates that the product is used for frozen desserts, and the identification indication 19b indicates The fact that it is for frozen desserts with little demand is displayed.

  Thereby, the user of the frozen dessert manufacturing apparatus 100 can surely put the raw mix of the frozen dessert that is frequently taken out into the mix tank 1a.

[Embodiment 2]
Another embodiment of the present invention will be described below with reference to FIGS.

Note that the sum of the rated power consumption of the unit 202 and the rated power consumption of the unit 203 needs to be less than or equal to the power that can be supplied by the power distribution system 602.

  The power distribution system 601 and the power distribution system 602 are connected to the external breaker 611 and the external breaker 612, respectively, and the rated current value of the external breakers 611 and 612 is, for example, 20A. Further, the power cable 242a and the power cable 242b are provided with a breaker 230a and a breaker 230b, respectively. The installation purpose of the breakers 230a and 230b is the same as the installation purpose of the breaker 130 (see FIG. 1) in the first embodiment, and the maximum allowable current in each of the breakers 230a and 230b is the power cable 241 when the frozen dessert manufacturing apparatus 200 is abnormal. Is set to be smaller than the maximum current flowing through the. That is, the rated current value of the breakers 230a and 230b is lower than the rated current value of the external breaker 612, for example, 10A.

  As a result, even when the current consumption is increased due to a failure in the unit 202 or the unit 203, even when the external breaker 612 is not activated, the breaker 230a or the breaker 230b is activated to cut off the power supply, so that safety is maintained. It is. The breakers 230a and 230b may be provided inside the casing of the frozen dessert manufacturing apparatus 200, or may be provided outside the casing of the frozen dessert manufacturing apparatus 200. Further, instead of the breakers 230a and 230b, a fuse may be provided as overcurrent protection means.
