The rotation shaft 10 </ b> A of the beater 10 is connected to the speed reducer 13 at the rear, and the rotation shaft 10 </ b> A of the beater 10 is coaxial with the central axis of the cooling cylinder 8.

  On the other hand, the freezer door 14 constituting the frozen dessert take-out portion 56 is detachably attached to the main body 1 with nuts 57... In the form of closing the front opening of the cooling cylinder 8. An extraction passage 59 extending vertically is formed through the freezer door 14, and the plunger 16 is inserted into the extraction passage 59 so as to be freely movable up and down.

  And the star-shaped nozzle 58 which comprises the nozzle for shape | molding frozen confectionery (soft cream) is attached to the lower end of this extraction channel | path 59. FIG. In the present embodiment, the star-shaped passage in the star nozzle 58 has a star-shaped cross section that constitutes the take-out passage 59 together with the take-out passage 59 in the freezer door 14.

  In the present embodiment, the frozen dessert portion 56 is constituted by the freezer door 14, the extraction lever 15, and the plunger 16 in which the extraction passage 59 and the extraction passage 61 are formed.

  Next, with reference to FIG.2 and FIG.4, the cooling device R of frozen dessert manufacturing apparatus SM is demonstrated. In FIG. 4, R is a reversible cooling device. Hereinafter, the cooling device R will be described. 18 is a compressor, 19 is a refrigerant discharged from the compressor 18, and the flow direction is different depending on whether a cooling cycle (solid arrow) or a heating cycle (broken arrow) is configured. On the contrary, the four-way valve 20 for switching is a water-cooled condenser.

  The capacitor 20 has a double pipe structure including an outer refrigerant pipe 67 and an inner water passage pipe 68, and the double pipe is spirally wound. The refrigerant flowing in the refrigerant pipe 67 is cooled by exchanging heat with the cooling water (tap water) that is always circulated in the water flow pipe 68 through the water-saving valve 63. That is, when the four-way valve 19 constitutes a cooling cycle, the high-temperature and high-pressure gas refrigerant discharged from the compressor 18 flows into the refrigerant pipe 67 of the condenser 20 via the check valve 21, where it is condensed and liquefied. It becomes a liquid refrigerant.

  When this liquid refrigerant exits from the check valve 22 through the dry core (dryer) 23, it is divided into two directions, one of which is depressurized through the cylinder cooling valve 24 and the cooling cylinder capillary tube 25 and flows into the cylinder cooler 11. Here, it evaporates and cools the cooling cylinder 8. The other is depressurized via the hopper cooling valve 26 and the preceding hopper capillary tube 27, flows into the hopper cooler 4, where it is also evaporated and cools the hopper 2, and then flows out through the subsequent capillary tube 28. To do.

  Then, the refrigerant gas after cooling the cooling cylinder 8 and the hopper 2 joins in the accumulator 30, and then forms a cooling cycle that returns to the compressor 18 through the four-way valve 19, and the cooling operation in which the refrigerant flows in the solid line direction is performed. Done. A hopper sensor (not shown) for detecting the temperature of the hopper 2 is attached to the hopper 2, and the temperature of the mix in the cooling cylinder 8 is substantially equal to the cooling cylinder 8 due to the temperature of the cooling cylinder 8. A cylinder sensor (not shown) for detecting the above is attached.

  By the way, in the cooling operation, it is necessary to keep the cooling cylinder 8 and the hopper 2 cooled to a predetermined temperature in order to obtain a high-quality frozen dessert (soft cream). Therefore, the above cylinder sensor for detecting the temperature of the cooling cylinder 8 is provided, and this cylinder sensor turns on the cylinder cooling valve 24 (ON), turns on the compressor 18 to perform cooling, and turns off the cylinder cooling valve 24 (closed). During this time, the hopper cooling valve 26 is opened / closed and the compressor 18 is turned on / off. That is, the cooling of the cooling cylinder 8 is prioritized and the hopper cooling valve 26 is turned on under the condition that the cylinder cooling valve 24 is turned off.

  After the sale is made under the above-described cooling operation, the mix is sterilized by the heating method when the store is closed. In this case, the cooling device R is switched from the cooling cycle to the heating cycle operation. That is, the four-way valve 19 is operated to cause the refrigerant to flow as indicated by a dotted arrow. Then, the high-temperature and high-pressure refrigerant gas from the compressor 18, that is, the hot gas, is divided into two hands through the four-way valve 19 and the accumulator 30, one directly to the cylinder cooler 11 and the other to the hopper cooling via the check valve 33. Each of them flows into the vessel 4 to generate a heat dissipation action, and the cooling cylinder 8 and the hopper 2 are heated at a predetermined sterilization temperature for a predetermined time.

  The liquefied refrigerant after heat dissipation joins via the cylinder hot gas valve 34 and the hopper hot gas valve 35, respectively, and then flows into the refrigerant pipe 67 of the capacitor 20 via the check valve 40, where it is separated into gas and liquid. Thereafter, the refrigerant gas exits from the refrigerant pipe 67 of the capacitor 20 and flows into the reverse solenoid valve (open / close valve) 36 and the reverse capillary tube 37 connected in parallel via the refrigerant pipe 69 connected to the downstream side of the check valve 21. The The refrigerant gas that has passed through the reverse electromagnetic valve 36 or the reverse capillary tube 37 forms a heating cycle that returns to the compressor 18 via the four-way valve 19 via the branch pipe 60 connected to the upstream side of the check valve 21.

  In FIG. 1 or 2, 50 is a control panel, 44 is an electrical box, and 45 is a drain receiver attached to the front surface of the main body 1 corresponding to the lower part of the freezer door 14. A water tap 55 is used to supply water to the hopper 2 and the cooling cylinder 8 during the mix cleaning. Furthermore, reference numeral 43 denotes a bypass valve, which plays a role of preventing overload of the compressor 18.

  With the above configuration, the operation of the soft ice cream manufacturing apparatus SM of the present invention will be described. Now, it is assumed that a predetermined amount of mix is introduced into the hopper 2 of the soft ice cream manufacturing apparatus SM, and the mix is also supplied from the mix supplier 9 into the cooling cylinder 8. In this state, when the cooling switch of the control panel 50 is operated, the control device starts operation, and executes each operation of cooling operation (cooling process, defrost process) and sterilization / cooling operation (sterilization process, cooling process). To do.

  First, the cooling operation will be described. In the pull-down (operation start), the control device determines whether or not the current mix temperature in the cooling cylinder 8 is equal to or higher than the cooling end temperature, for example, + 0.5 ° C. And since the temperature of the mix at the time of pull-down is high, a control apparatus performs a cooling process.

  In this cooling process, the control device operates the compressor 18 and sets the four-way valve 19 to the cooling cycle (non-energized). Then, the cylinder cooling valve 24 is turned on (opened), the hopper cooling valve 26 is turned off (closed), and the cylinder hot gas valve 34 and the hopper hot gas valve 35 are turned off. Further, the beater 10 is rotated by the beater motor 12.

  Thereby, the mix in the cooling cylinder 8 is cooled by the cylinder cooler 11 and the temperature rapidly decreases, and the mix in the cooling cylinder 8 is stirred by the beater 10.

  As the cooling process proceeds, the temperature of the mix in the cooling cylinder 8 decreases, and when the temperature approaches the freezing point unique to the mix, the temperature effect gradually slows down. Has hardness. And since the load of the beater 10 which is stirring it increases with the hardness of frozen confectionery (soft cream), the energization current of the bitter motor 12 rises.

  When the energizing current of the beater motor 12 exceeds the threshold value, the control device sets the current mix temperature to the cooling end temperature (OFF point temperature) and stops cooling. That is, in this cooling stop, the control device turns off the cylinder cooling valve 24 and turns on the hopper cooling valve 26 instead. As a result, the cooling of the cooling cylinder 8 is stopped, and the hopper 2 is now cooled by turning on the hopper cooling valve 26. This ends the pull-down.

  Thereafter, the control device determines whether or not the current mix temperature in the cooling cylinder 8 has risen to the cooling end temperature (OFF point temperature) + 0.5 ° C. or higher. When the temperature in the hopper 2 is also cooled below a predetermined temperature, the control device turns off the hopper cooling valve 26 and also stops the compressor 18 in this case. In the embodiment, the hopper cooling valve 26 is turned on at 10 ° C. and turned off at 8 ° C.

  When the temperature of the frozen dessert in the cooling cylinder 8 rises to the cooling end temperature (OFF point temperature) + 0.5 ° C. or higher, the control device starts cooling the cooling cylinder 8 again, and thereafter repeats this. Is.

  In this way, the frozen dessert is manufactured in the cooling cylinder 8. When selling frozen dessert, the plunger 16 is pulled up by pulling the take-out lever 15 forward, and the outlet 61A of the extraction path 61 is opened. In the cooling cylinder 8, the pressure is applied in the direction of pushing forward while rotating the frozen dessert by the rotation of the beater 10, so that the frozen dessert in the cooling cylinder 8 exits from the outlet 61 </ b> A of the extraction path 61 and enters the extraction passage 59. Then, it is extracted through the star nozzle 58 at the lower end.

  Next, the sterilization / cooling operation (sterilization process, cooling process) will be described. When the sterilization switch of the control panel 50 is operated, the control device performs the sterilization process after determining that the condition is that the mix does not run out.

  In this case, the control device switches from the cooling cycle to the heating cycle by the four-way valve 19. Thereby, hot gas is supplied to the cooling cylinder 8 and the hopper 2 and heated (sterilization temperature rise). When the sterilization temperature rise is completed, the control device controls the compressor 18, the cylinder hot gas valve 34, and the hopper hot gas valve 35 to be turned on and off based on the mix temperature in the hopper, and the cooling cylinder 8. The hopper 2 is sterilized and held so as to satisfy a total heating time of about 30 minutes at a heating temperature of + 68 ° C. or higher.

  When this sterilization temperature rise and sterilization holding is completed, the control device shifts to a cold pull-down. In this cold insulation pull-down, the temperature of the cooling cylinder 8 and the hopper 2 is cooled to a temperature of + 10 ° C. or lower under the condition that the temperature is lower than the predetermined temperature within a predetermined time. And if it falls to +10 degrees C or less, a control apparatus will transfer to a cold preservation process.

  Next, the cover 46 according to the present invention will be described in detail with reference to FIGS. 3, 5, and 6. FIG. 5 is an enlarged perspective view of the frozen dessert take-out portion 56, and FIG. 6 is a perspective view of the cover 46. The cover 46 is a see-through cover member that is provided from the front of at least the frozen dessert outlet 58A (the lower end opening of the star nozzle 58) to the front lower side of the outlet 58A. In this embodiment, the material is a colorless and transparent material, and is made of, for example, polyethylene terephthalate (PET) in order to ensure a predetermined strength.

  In this embodiment, the freezer door 14 in which the frozen dessert outlet 58A is formed (provided) is provided in close contact with the front surface of the main body 1, and the attachment portion 14A in which the extraction path 61 is formed, and the attachment The extraction portion 14B is located on the front side of the portion 14A and has an extraction passage 59 formed therein, and the extraction portion 14B is formed with a width dimension smaller than the mounting portion 14A by a predetermined dimension. The extraction part 14B has a stepped shape protruding forward.

  Therefore, the cover 46 in this embodiment includes a front plate 47 that covers the front surface of the take-out portion 14B of the freezer door 14 and the front lower portion of the frozen dessert outlet 58A by extending a predetermined dimension downward, and both sides of the front plate 47. Side plates 48, 48 that are bent rearward along both side surfaces of the extraction portion 14B, and attachment pieces 49, 49 formed at the rear ends of the side plates 48 across the front surface and side surfaces of the attachment portion 14A, Consists of

  As shown in FIG. 3, the lower end of the front plate 47 is also formed in the freezer door 14 at least from the lower end (point A) of the extraction path 61 formed in the freezer door 14. The point where the front plate 47 of the cover 46 intersects with the lower edge front end of the take-out passage 59 located on the front side, that is, the line connecting the lower edge front end (point B) of the frozen dessert outlet 58A (star nozzle 58). (Point C) Located at the following height.

  Further, as the lower end of the front plate 47 extends to a lower position, it becomes possible to suppress the scattering of the frozen dessert from the frozen dessert outlet 58A. Since the container or the operator's hand hits the front plate 47 at the time of serving, it is desirable that the height satisfies the above conditions and does not cause the inconvenience. In the soft ice cream manufacturing apparatus SM in the present embodiment, the size satisfying each condition is set to a position extending about 5 cm downward from the lower end of the frozen dessert outlet 58A, that is, the star nozzle 58.

  Further, a reinforcing flange 51 is formed on the upper edge of the front plate 47 by bending it to the freezer door 14 side. Thereby, the strength of the cover 46 in the longitudinal direction can be improved.

  The attachment piece 49 in the present embodiment is formed to extend from the upper end of the side plate 48 to a position corresponding to the lower end of the freezer door 14, and the front face 49 </ b> A of the attachment piece 49 is directed upward from the lower end. A notch 49B is formed. Both cutouts 49B are removably supported from above by nuts 57, 57 at the lower corners used for fixing to the main body 1 at the attachment portion 14A of the freezer door 14.

  Further, the rear end of the side surface 49 </ b> C of the mounting piece 49 is configured to abut on the front surface of the main body 1 while being supported by the nuts 57 and 57.

  With the cover 46 having such a structure, the left and right attachment pieces 49, 49 are engaged with the nuts 57, 57 on the main body 1 side, and the extraction operation in the frozen dessert extraction portion 56 is allowed. Covers the front and lower front.

  Here, when the operation of taking out the frozen dessert is performed continuously by the operation of the takeout lever 15, there arises a disadvantage that the frozen dessert in the extraction path 61 in the freezer door 14 is melted by heat conduction from the outside. However, for example, when a relatively long time elapses from the previous frozen confection removal to the current frozen confection removal, the frozen confection in the extraction passage 61 formed in the frozen confection removal unit 56, that is, the freezer door 14, is externally exposed. It becomes easy to dissolve by heat conduction. In such a case, if the soft ice cream is taken out by operating the take-out lever 15 as described above, the liquid mix in the extraction path 61 is caused by the rotation of the beater 10 in the cooling cylinder 8 and the atmospheric pressure. In relation, it blows out vigorously from the frozen dessert outlet 58A.

  At this time, since the frozen dessert blown toward the lower side of the freezer door 14 is received by the drain receiver 45, there is no inconvenience that the frozen dessert adheres to the surrounding area or the operator, but the pressure due to the rotation of the beater 10 is In particular, when the plunger 16 ascends and the lower edge of the frozen dessert outlet 58A begins to open into the take-out passage 59, the liquid frozen dessert blows out vigorously toward the front and the front lower side.

  In the present embodiment, as described above, since the cover 46 is provided from the front of the frozen dessert outlet 58A to the front and lower side in a state in which the removed operation at the frozen dessert extraction unit 56 is permitted, the liquid mix is blown out. Even in this case, it is possible to prevent inconveniences that are scattered in the vicinity of the worker who is extracting the frozen dessert and located around the front or lower front of the frozen dessert outlet 58A and contaminating them.

  In particular, since the cover 46 can be seen through, it is possible to take out the frozen dessert while visually checking the state of the frozen dessert taken out from the frozen dessert outlet 58A when performing the operation of taking out the frozen dessert. It is possible to avoid inconvenience that the operability is deteriorated.

  Further, as described above, in the cover 46 in this embodiment, the lower end of the front plate 47 is connected to the line connecting the lower end 61A of the extraction path 61 in the freezer door 14 and the lower edge front end of the frozen dessert outlet 58A. 47 is located below the point where it intersects with 47, the front plate 47 of the cover 46 can receive the frozen dessert blown forward or forward and downward from the frozen dessert outlet 58A, and in front of the device SM. Thus, it is possible to effectively avoid the inconvenience that the frozen dessert is scattered and contaminated by an operator who performs the frozen dessert removal operation.

  Furthermore, the cover 46 in the present embodiment is easily freezer by engaging the locking pieces 49, 49 formed at both ends with nuts 57, 57 for detachably attaching the freezer door 14 to the main body 1. It can be attached to the door 14. Therefore, by using the nut 57 for attaching the cover 46 without providing any special means for attaching the cover 46 to the main body 1 (freezer door 14), the number of parts can be reduced and the cover 46 can be reduced. Thus, it is possible to prevent the inconvenience that the liquid frozen dessert blown out from the frozen dessert outlet 58A formed at the lower end of the freezer door 14 scatters forward or forward and downward and contaminates the operator and the surrounding area.

  In particular, since the cover 46 is detachably supported by a nut 57 that protrudes forward from the freezer door 14, the cover 46 can be attached and detached even with one hand. Can be improved. Moreover, since it can be easily removed, the cover 46 can be separately cleaned, which is advantageous in terms of hygiene.

  Further, in a state where the cover 46 is supported by the nuts 57, 57, the rear end of both sides of the cover 46, that is, the rear end 49C of the locking piece 49 abuts the front surface of the main body 1, so that it is attached in a stable state. It becomes possible. Therefore, it is possible to avoid the disadvantage that the frozen dessert comes into contact with the cover 46 during the extraction operation and the commercial value is lost by the unstable mounting of the cover 46.

  The cover 46 is not limited to the above-described embodiment. For example, like the cover 64 shown in FIG. 7, these covers 46 may be provided on the inside or outside of the front plate 47 or the front plate 47 and the side plates 48 and 48. It is good also as a structure which is equipped with the slide board 53 which superposes and slides to an up-down direction, and can expand-contract the up-down dimension of the cover 64. FIG. Specifically, elongated holes 52 and 52 extending in the vertical direction are formed in the front plate 47, and the locking member 54 provided on the upper portion of the slide plate 53 is slidable up and down in the elongated hole 52. It can be moved.

  By adopting such a configuration, in a situation where the liquid frozen confectionery at the beginning of extraction is likely to scatter, the use of the cover 64 with the slide plate 53 lowered to the lower side avoids the inconvenience that the confectionery scatters further to the operator and the surrounding area. can do. On the other hand, in the situation where the extraction of the frozen confectionery is stable and the liquid frozen confectionary is almost absent, the use of the cover 64 with the slide plate 53 of the cover 64 contracted to the upper side can improve the workability of extracting the frozen confectionery. .

  Thereby, even if the cover 64 is not removed, it is possible to improve the arrangement (extraction) workability while avoiding the scattering of the liquid frozen dessert without trouble.

  In each of the above-described embodiments, the extraction of the frozen dessert from the cooling cylinder 8 employs a structure using the plunger 16, but is not limited to this. For example, a motor or solenoid is operated by a button operation or the like. The same effect can be obtained even if the frozen dessert is taken out by using an electrical take-out device such as operating and opening the frozen dessert outlet 58A.
