And the front-end | tip (other end) of this mix raw material tube 34 is detachably connected to one inlet 57A of the Y-type mixer 57 by the connection tool 67 of this invention.

  Next, the specific structure of the connector 67 and the operation of connecting the mix raw material tube 34 to the Y-type mixer 57 using the same will be described with reference to FIGS. Each of the connecting members 67 includes a pair of connecting members 91 and 92 (91 is a first connecting member and 92 is a second connecting member) made of a hard synthetic resin, and a C-shaped spring member 93 (attached). For example). Both connecting members 91 and 92 have connecting portions 91A and 92A formed to project outward (FIGS. 8 and 9), and the other shapes are substantially plane-symmetrical. And these connection parts 91A and 92A are connected with the pin 94 so that rotation is possible, and, thereby, both the connection members 91 and 92 are connected so that rotation is mutually possible. The connecting member 67 formed by connecting both connecting members 91 and 92 has a generally cylindrical shape with one end side (upper part in the figure) narrowed and both ends (upper and lower parts in the figure) open (see FIG. FIG. 7).

  Nipping portions 91B and 92B protrude from the inner surface one end side (upper inner surface in the drawing) of both connection members 91 and 92 at positions facing each other. Both sandwiching portions 91B and 92B have an arrowhead shape in cross section (FIG. 11), and in a direction (horizontal direction in the figure) perpendicular to the axis of the cylinder along the opposing surfaces (the inner surfaces thereof) of both connection members 91 and 92. It extends in a straight line. In addition, relief portions 91C and 92C are formed as recesses at both ends of the sandwiching portions 91B and 92B, respectively. Engaging portions 91D and 92D project from the inner surfaces of the other end portions of the connecting members 91 and 92 (the inner surfaces of the lower ends in the drawing) at positions facing each other. Both engaging portions 91D and 92D protrude along the curved inner surface shape of both connection members 91 and 92, and have a cross-sectional arrowhead shape inclined so that the inner surface expands toward one end (FIG. 8, 9 and 11).

  Grooves 91E and 92E are formed at the center of the outer surface of both connection members 91 and 92, and the spring member 93 can be attached to and detached from the grooves 91E and 92E from the outside in a state where both connection members 91 and 92 are connected. The connecting tool 67 is completed.

  Next, a procedure for connecting the mix raw material tube 34 to one inlet 57A of the Y-shaped mixer 57 using the connection tool 67 having the above configuration will be described. In this case, a flange 97 is formed around the inlets 57A and 57B of the Y-type mixer 57, and a circular through hole 96A is provided in the center on the tip side of the flange 57C of one inlet 57A. The formed sealing material 96 (made of soft rubber or the like) is detachably attached.

  First, the spring member 93 is not attached to the connection tool 67. In this state, both connecting members 91 and 92 are rotated around the pin 94 to separate the opposing surfaces and open them. Then, the mix raw material tube 34 whose tip is sealed by heat welding is sandwiched between the center of the connecting members 91 and 92. At this time, the mix raw material tube 34 is inserted from one end on the holding portion 91B, 92B side of the connection tool 67, and is sandwiched in a state protruding slightly from the other end on the engaging portion 91D, 92D side.

  Then, the spring member 93 is fitted in the grooves 91E and 92E from the outside so as to be detachable. The spring member 93 is constantly biased in the direction in which both the sandwiching portions 91B and 92B are close to each other, that is, the mix raw material tube 34 side, and the engaging portions 91D and 92D are always biased in the direction in which they are close to each other. Both clamping parts 91B and 92B face each other at a predetermined interval. At this time, the gap between the sandwiching portions 91B and 92B is smaller than twice the wall thickness of the mix raw material tube 34. As a result, the mix raw material tube 34 has both ends as shown in FIGS. The inner passage is sealed by being crushed by the sandwiching portions 91B and 92B. The crushed portion of the mix material tube 34 protrudes into the escape portions 91C and 92C.

  In this way, the connection tool 67 is attached to the mix raw material tube 34, and the mix raw material tube 34 is crushed by the clamping portions 91B and 92B of the connection tool 67 so as to seal the internal passage and protrude from the connection tool 67. The portion of the mix raw material tube 34 is cut and the tip is opened. At this time, since the passage in the mix raw material tube 34 is sealed by the sandwiching portions 91B and 92B, the mix in the bag body 21 does not leak out.

  Next, the tip of the mix raw material tube 34 is inserted into the through hole 96A of the sealing material 96 attached to one inlet 57A of the Y-shaped mixer 57 and inserted into the inlet 57A. In this process, the engaging portions 91D and 92D of both connecting members 91 and 92 of the connecting tool 67 abut against the opening 57A side of the flange portion 97, and resist the spring member 93 along the inclination of the engaging portions 91D and 92D. When the connecting members 91 and 92 are separated from each other, the engaging portions 91 </ b> D and 92 </ b> D get over the flange portion 97 and are detachably engaged on the opposite side by the urging force of the spring member 93. That is, the spring member 93 urges both the engaging portions 91 </ b> D and 92 </ b> D in a direction that always engages with the Y-type mixer 57.

  In a state where the engaging portions 91D and 92D are engaged with the flange portion 97 of the Y-type mixer 57, the flange portion 57 abuts against the inner surfaces of both connection members 91 and 92, and the engagement portions 91D and 92D are Y-shaped. By contacting the outer surface of the mixer 57, both the connecting members 91 and 92 are rotated in a direction slightly separated from the states shown in FIGS. 10 and 11 (FIGS. 12 and 13). As a result, the holding portions 91B and 92B are also slightly separated, so that the passage in the mix raw material tube 34 is opened as shown in FIGS. 16 and 17, but the holding portions 91B and 92B are still pressed against the outer surface of the mix raw material tube 34. And pinch. Therefore, the mix raw material tube 34 does not come out of the connection tool 67.

  As a result, the sealing of the mix raw material tube 34 is released, and the inside of the bag main body 21 of the mixed raw material bag 5 and the inside of the cooling cylinder 8 are communicated with each other via the mixed raw material tube 34 and the Y-type mixer 57. Further, since the inner surface of the through hole 96A of the sealing material 96 is in close contact with the outer surface of the mix material tube 34, the inside of the mix material tube 34 and the Y-type mixer 57 is sealed from the outside. Furthermore, the connection tool 67 is rotatable with respect to the mix raw material tube 34 in the state. Thereby, the twist of the mix raw material tube 34 can be corrected.

  On the other hand, the other end of the air circuit 51 is also detachably connected to the other inlet 57B of the Y-type mixer 57 by a connector 69. The outlet of the Y-type mixer 57 is detachably connected to the mix inlet 9 of the cooling cylinder 8 via an O-ring 71. By detachably connecting in this way, cleaning of the mix raw material tube 34, the Y-type mixer 57, etc. becomes easy.

  Next, in FIG. 4, reference numeral 73 denotes a general-purpose microcomputer constituting control means. The input of the microcomputer 73 is connected to the cool box open / close switch 33, the air circuit sensor 47, the proximity switch 38, and the reed switch 37. Has been. Further, a pull-down switch (operation switch) 76 and a cooling switch 77 provided on the control panel 74 of the main body 1 are further connected to the input of the microcomputer 73.

  Further, in addition to the compressors 18 and 18A of the cooling device R and the beater motor 12 described above, the exhaust solenoid valve 48 in the air circuit, the air pump 27, and the air circuit open / close solenoid valve 52 are connected to the output of the microcomputer 73. . Furthermore, a sold-out display lamp 78 provided on the operation panel 74 is connected to the output of the microcomputer 73.

  Next, the operation of the above configuration will be described. When a power plug (not shown) of the frozen dessert manufacturing apparatus SM is connected to the power source and turned on, the microcomputer 73 first determines whether or not the contact of the reed switch 37 is closed. Then, if the freezer door 14 is attached and the front opening of the cooling cylinder 8 is closed and the permanent magnet 36 closes the contact of the reed switch 37, the start of the subsequent operation is allowed, but the freezer door 14 is normally operated. If it is not attached and the contact of the reed switch 37 is open, the start of the subsequent operation is prohibited, for example, the sold-out display lamp 78 is blinked to display an alarm. As a result, forgetting to attach the freezer door 14 or preventing the operation from being started in a state where the freezer door 14 is not properly installed is prevented, and the user is prompted to install the freezer door 14.

  Next, with reference to the timing charts of FIGS. 5 and 6, the manufacture of frozen confectionery and the extraction operation of frozen confectionery will be described. In addition, the mix raw material bag 5 is set in the storage 2A of the cool box 2 in a state where it can be delivered in a state of being stored in the bag case 31 as described above. In this state, the bag pressurizing pipe 7, the mix raw material tube 34, and the Y-type mixer 57 are also connected as described above. However, the air circuit 51 is removed from the Y-type mixer 57 at this point when pull-down starts.

(1) Initial State In the initial state after the power is turned on in FIG. 5, the microcomputer 73 first opens the air circuit exhaust solenoid valve 48 for a predetermined period (5 seconds in the embodiment). After that, after setting the mixed material bag 5 in the inside 2A of the cool box 2 as described above and detecting that the heat insulating door 3 is closed based on the detection operation of the cool box opening / closing switch 33, the microcomputer 73 Operates the air pump 27. Thereafter, when the heat insulating door 3 of the cool box 2 is opened, the microcomputer 73 stops the air pump 27 based on the detection operation of the cool box opening / closing switch 33 and exhausts the electromagnetic valve in the air circuit for a predetermined period (5 seconds). 48 is opened and exhausted from the air circuit 51 and the bag pressurizing pipe 7.

  In other words, the microcomputer 73 stops the air pump 27 when the heat insulating door 3 of the cool box 2 is opened, and allows the operation of the air pump 27 only when the heat insulating door 3 is closed. Thereby, the safety | security at the time of attachment or detachment of the pipe etc. in the case of replacement | exchange of the mix raw material bag 5 improves. In particular, when the heat insulating door 3 is opened, the exhaust electromagnetic valve 48 in the air circuit is opened and the compressed air is discharged from the air circuit 51 or the bag pressurizing pipe 7, so that the compressed air blows out when the pipe is attached or detached. Can be reliably avoided.

  In this initial state, after the air pump 27 is operated, the sensor 47 in the air circuit communicates with the bag pressurizing pipe 7 (communication with the bag pressurizing pipe 7) even after 3 minutes have passed. If the pressure rise in the air circuit 51 is not detected), the air pump 27 is stopped, and the sold out display lamp 78 is blinked. Alarm.

(2) Pull-down mode Next, when the user turns on the pull-down switch 76 (presses for less than 2 seconds), the microcomputer 73 enters the pull-down mode and starts pull-down. In this pull-down mode, the microcomputer 73 operates the air pump 27, and the bag pressurizing pipe 7 communicated by the distributor 46 (the bag body 21 and the outer layer 23 of the mixed material bag 5 communicating with the bag pressurizing pipe 7). Compressed air is supplied into the air circuit 51 (in the pull-down mode, the air circuit opening / closing solenoid valve 52 is closed).

  When the air pressure detected by the air circuit sensor 47 rises to a set value, the microcomputer 73 stops the air pump 27 based on the output of the air circuit sensor 47. After that, the microcomputer 73 starts counting a 3-minute timer (a predetermined value not limited to 3 minutes) that is included in the microcomputer 73.

  Compressed air is sent from the bag pressurizing pipe 7 into the sealed space between the outer layer body 23 of the mixed material bag 5 and the bag body 21, whereby a constant pressure is applied to the bag body 21 from the outside. As a result, the volume of the sealed space between the outer layer body 23 and the bag body 21 is expanded, so that the mix in the bag body 21 is pushed out from the outlet member 22 to the mix material tube 34. The mix pushed out to the mix raw material tube 34 passes therethrough, and then flows into the cooling cylinder 8 from the mix inlet 9 through the Y-type mixer 57 and the check valve 54. At this time, since the air circuit 51 is disconnected, the air in the cooling cylinder 8 exits from the other outlet 57B of the Y-type mixer 57. As a result, the mix also smoothly flows into the cooling cylinder 8.

  Since the mix flows out from the mix raw material bag 5, the volume of the sealed space between the outer layer body 23 and the bag body 21 is expanded, so that the air pressure in the pipe from the bag pressurizing pipe 7 to the distributor 46 is also reduced. When the air circuit sensor 47 detects that the pressure has dropped to a predetermined lower limit value, the microcomputer 73 operates the air pump 27 to resume the supply of compressed air. By repeating this, the microcomputer 73 sets the air pressure (air pressure in the sealed space between the outer layer body 23 of the mixed material bag 5 and the bag body 21) detected by the air circuit sensor 47 between the set value and the lower limit value (set value). And a predetermined pressure in the range of the lower limit).

  Thereafter, this is continued until the count of the 3-minute timer is completed, and the mix is fed into the cooling cylinder 8. As a result, the mix is stored in the cooling cylinder 8. When the count of the 3-minute timer is completed, the microcomputer 73 stops the operation of the air pump 27, opens the exhaust electromagnetic valve 48 in the air circuit for 5 seconds, and discharges the compressed air once. The user checks the liquid level of the mix in the cooling cylinder 8 through the transparent freezer door 14, and when the liquid level does not reach the predetermined liquid level, the user continues to hold down the pull-down switch 76 (ON for 2 seconds or more).

  When the pull-down switch 76 is continuously turned on, the microcomputer 73 operates the air pump 27 to start supplying compressed air again. As described above, the air pressure detected by the sensor 47 in the air circuit (mixed material bag 5 The air pressure in the sealed space between the outer layer body 23 and the bag body 21 is maintained at a set value. As a result, the mix is again fed into the cooling cylinder 8 from the mix material bag 5. When the user visually confirms that the mix in the cooling cylinder 8 has been stored up to a predetermined liquid level and releases the pull-down switch 76 (OFF), the microcomputer 73 stops the air pump pump 27, The air solenoid exhaust valve 48 in the air circuit is opened to discharge the compressed air in the sealed space between the outer layer body 23 of the mixed material bag 5 and the bag body 21. As a result, the feeding of the mix is stopped, and the mix is stored in the cooling cylinder 8 to a predetermined liquid level.

  By providing such a pull-down mode in the microcomputer 73, the mix can be smoothly stored in the cooling cylinder 8 when the store is opened. In particular, since the pull-down switch 76 is provided and the pull-down can be started manually, the usability is also improved.

  After storing the mix up to a predetermined liquid level in the cooling cylinder 8 in this way, the heat insulating door 3 is opened, and the air circuit 51 is connected to the other inlet 57B of the Y-type mixer 57 in the inside 2A of the cool box 2. Close the heat insulating door 3. When the heat insulating door 3 is opened, the microcomputer 73 stops the air pump 27 and opens the exhaust electromagnetic valve 48 in the air circuit to discharge the compressed air as described above, but after the air circuit 51 is connected, the heat insulating door 3 is opened. Is closed, the air pump 27 is operated again to detect the air pressure detected by the air circuit sensor 47 (the bag pressurizing pipe 7 including the sealed space between the outer layer body 23 of the mixed material bag 5 and the bag body 21 and the distributor 46). And the air pressure to the air circuit opening / closing solenoid valve 52 in the air circuit 51) is increased to a set value.

  When the air pressure detected by the air circuit sensor 47 rises to the set value, the microcomputer 73 opens the air circuit opening / closing electromagnetic valve 52 for a predetermined period (for example, 5 seconds) and compresses the air circuit 51 to the Y-type mixer 57. Bring in air. The pressure of the compressed air flowing into the cooling cylinder 8 from the air circuit 51 through the Y-type mixer 57 prevents the mix from flowing into the cooling cylinder 8 from the mix material tube 34.

  At this time, an overrun of the frozen dessert (a state in which air is mixed in the frozen dessert and the volume increases) is obtained depending on the amount of compressed air flowing into the cooling cylinder 8. The liquid level of the mix to be performed can be defined at a predetermined liquid level by operating the pull-down switch 76 or the position of the liquid level sensor, so that the amount of air in the cooling cylinder 8 can also be defined. Will be able to be set.

  At this time, since the compressed air flowing into the cooling cylinder 8 has passed through the air filter 53, foreign matter and germs contained in the air are captured by the air filter 53. As a result, it is possible to avoid the inconvenience that foreign matters and various germs are mixed with the compressed air in the cooling cylinder 8, and hygiene management can be reliably performed.

  Furthermore, since the mix raw material tube 34 and the air circuit 51 are once merged in the Y-type mixer 57 as described above, they are communicated with the cooling cylinder 8 from the mix inlet 9. Both the supply of the mix and the supply of overrun air can be performed from the single mix inlet 9, and the structure of the cooling cylinder 8 can be simplified.

  This is the end of the pull-down mode. In this state, the operation of the cooling switch 77 is awaited. The microcomputer 73 counts and holds the pull-down time required to store the mix in the cooling cylinder 8 from the time when the pull-down switch 77 is first operated to the predetermined liquid level as described above. In this case, when the mix is stored up to a predetermined liquid level by visually operating the pull-down switch 77 as described above, the count of the pull-down time is finished when the pull-down switch 77 is finally released, and the liquid as described above. When the mix is stored up to a predetermined liquid level by the position sensor, the pull-down time is counted when the liquid level sensor detects the predetermined liquid level of the mix.

(3) Normal Sales Mode Next, moving to FIG. 6, when the cooling switch 77 is turned on (pressed) by the user, the microcomputer 73 confirms that the freezer door 14 is normally attached and closed as described above. As a condition, the compressor 18 of the cooling device R is operated to start the cooling operation. When the compressor 18 is operated, the refrigerant condensed in the condenser 20 is supplied to the cylinder cooler 11 through a decompression device (not shown), and evaporates there to exert a cooling action. Further, the compressor 18 is also operated, and the mix of the mix material bag 5 in the inside 2A of the cool box 2 is kept cold by the cool box cooler 4 as described above. Furthermore, the components (such as the portion surrounded by a two-dot chain line in FIG. 2) such as the mixed raw material tube 68 and the other end of the air circuit 51 in the interior 2A and the Y-type mixer 57 are also kept cold. In this way, the temperature of the mix and compressed air flowing into the cooling cylinder 8 does not rise in the process of passing through them.

  On the other hand, in the cooling cylinder 8, the mix is cooled to the freezing temperature by the cylinder cooler 11, and the microcomputer 73 rotates the beater 10 by the beater motor 12, so that the semi-cured frozen dessert ( Soft ice cream) is produced. After that, it becomes a sales standby state.

  In this state, for example, when the user takes out a cone (container), for example, below the take-out lever 15 and brings it close to the proximity switch 38, the proximity switch 38 detects the cone and turns on (sales detection). When the proximity switch 38 is turned on, the microcomputer 73 starts counting the timer for sales detection 3 seconds (a predetermined period not limited to 3 seconds) that the microcomputer 73 has as its function. When the timer continues counting for 3 seconds, that is, when the proximity switch 38 continuously detects the cone for 3 seconds, the microcomputer 73 rotates the beater 10. When the user operates the take-out lever 15, the plunger 16 is raised as described above, so that the frozen dessert (soft cream) is pushed out by the beater 10 into an extraction path (not shown) and extracted into a cone.

  As described above, since the rotation of the beater 10 is controlled using the proximity switch 38, there is no need to provide a take-off switch using an arm that interlocks with the vertical movement of the plunger 16 as in the prior art, and the number of parts can be reduced. Since the mechanism is simplified, failure is less likely to occur. In addition, since the beater 10 is rotated when a cone is detected continuously for a predetermined period (3 seconds), a malfunction that occurs when a hand is accidentally held near the proximity switch 8 is prevented. it can.

  If the extraction lever 15 is returned, the plunger 16 descends and the extraction path is blocked. If the cone is separated from the proximity switch 38, the microcomputer 73 stops the beater 10. Thereby, extraction of frozen dessert stops. Since the pressure is reduced by extracting the frozen dessert from the cooling cylinder 8, it is cooled from the bag main body 21 of the mix raw material bag 5 through the mix raw material tube 34, the check valve 54 and the Y-type mixer 57 from the mix inlet 9. The mix flows into the cylinder 8 and is replenished.

  In this case, since the air circuit 51 is provided with the check valve 56, the inconvenience of the mix entering the Y-type mixer 57 from the mix raw material tube 34 into the air circuit 51 at this time is avoided. Therefore, it is not necessary to clean the air circuit 51 upstream of the check valve 56.

  On the other hand, the microcomputer 73 opens the air circuit opening / closing solenoid valve 52 for b seconds (predetermined period) after a second (delay time) from the sales detection. When the air circuit 51 is opened by the air circuit opening / closing solenoid valve 52, the mix from the mix material tube 34 to the cooling cylinder 8 is performed by the pressure of the compressed air flowing from the air circuit 51 through the Y-type mixer 57 into the cooling cylinder 8. Inflow is blocked and stopped as before. That is, the mix can be supplemented from the mix material tube 34 into the cooling cylinder 8 by opening the air circuit opening / closing electromagnetic valve 52 with a delay from the start of extraction of the frozen dessert from the cooling cylinder 8.

  In the embodiment of FIG. 6, the air circuit opening / closing electromagnetic valve 52 is continuously opened for b seconds, but the air circuit opening / closing electromagnetic valve 52 may be opened / closed intermittently a plurality of times after a second.

  Here, the replenishment amount of the mix at this time is determined by the delay time of a seconds, and the amount of the mix flowing into the cooling cylinder 8 during this delay time varies depending on the viscosity of the mix. That is, when the viscosity of the mix is high at the same delay time, the replenishment amount decreases, and when the viscosity is low, the replenishment amount increases. On the other hand, when the viscosity of the mix is high, the time required for the pull-down described above (pull-down time) becomes long, and when the viscosity is low, the time becomes short.

  Therefore, based on the pull-down time counted and held as described above, the microcomputer 73 extends the delay time of a seconds when the pull-down time is long, and shortens it when the pull-down time is short. As a result, the amount of the mix replenished into the cooling cylinder 8 with the extraction of the frozen dessert can be made substantially constant regardless of the viscosity of the mix. And a lack of mixing in the cooling cylinder 8 can be avoided.

  Here, the microcomputer 73 performs ON / OFF control of the air pump 27 so as to maintain the pressure detected by the air circuit sensor 47 at the set value described above. With the extraction of the frozen dessert as described above, the mix flows out from the mix raw material bag 5, and the pressure detected by the air circuit sensor 47 gradually increases as air flows into the cooling cylinder 8 from the air circuit 51. Although the pressure decreases, the pressure drops to the lower limit after approximately five extractions, and the air pump 27 is operated.

  Therefore, in most cases except for an extremely rare situation where extraction is performed six times or more continuously, the air pump 27 is not operated while the air circuit opening / closing electromagnetic valve 52 is opened for b seconds as described above. Therefore, during this b seconds, the compressed air in the sealed space between the outer layer body 23 of the mixed material bag 5 and the bag body 21 enters the air circuit 51 via the bag pressurizing pipe 7 and the distributor 46, and the air It flows into the cooling cylinder 8 through the circuit opening / closing electromagnetic valve 52, the air filter 53 and the Y-type mixer 57.

  The compressed air in the sealed space between the outer layer body 23 of the mix raw material bag 5 and the bag main body 21 is air cooled in the interior 2 </ b> A of the cool box 2. That is, since the compressed air having a low temperature is supplied from the air circuit 51 into the cooling cylinder 8, the volume is not bulky, which is advantageous for overrun.

  Moreover, by sealing the air pressure in the sealed space between the outer layer body 23 of the mixed material bag 5 and the bag body 21 using the air pump 27 and the sensor 47 in the air circuit in this way, the sealed space between them is sealed. Since the volume is increased and the mix stored in the bag main body 21 is pushed out to the mix raw material tube 34, automatic supply of the mix from the bag main body 21 to the cooling cylinder 8 can be realized. This eliminates the gravity-dependent mix supply system that uses the mix supply pipe as in the prior art, and enables stable automatic supply of the mix. The mix is directly cooled from the mix material bag 5 to the cooling cylinder 8. By supplying to, hygiene problems can be solved.

  Further, the air pressure in the sealed space between the outer layer body 23 of the mixed material bag 5 and the bag body 21 is set to a predetermined pressure between the set value and the lower limit value by using the air pump 27 and the air circuit sensor 47 in this way. The mix is pushed out from the bag body 21 to the mix material tube 34 by the air pressure and supplied to the cooling cylinder 8 and the air circuit opening / closing solenoid valve 52 is opened to allow the compressed air from the air circuit 51 to flow in. Accordingly, the replenishment of the mix from the mix raw material tube 34 is stopped, so that it is not necessary to provide an electromagnetic valve or the like for controlling the supply of the mix on the mix raw material tube 34 side. This makes the cleaning operation extremely easy.

(4) When sold out When the above-described sales operation is performed and the mix in the bag body 21 of the mix raw material bag 5 is lost, there is no mix to be replenished even if the frozen dessert is extracted after the sale is detected. The change in pressure detected by the in-circuit sensor 47 does not occur or becomes extremely small. In the embodiment, when there is no change in pressure after the sales are detected, the microcomputer 73 determines that the selling is out and turns on the sold-out display lamp 78 continuously (ON). Further, the operation of the air pump 27 is also stopped.

(5) Bag replacement When the user confirms that the mix is sold out by turning on the sold-out display lamp 78 and opens the heat insulating door 3 for replacement, the microcomputer 73 sets the air circuit exhaust solenoid valve 48 for 5 seconds as described above. Open to discharge compressed air. Thereafter, the bag pressurizing pipe 7 and the mix raw material tube 34 are removed, and the mixed raw material bag 5 which is empty together with the bag case 31 is taken out. When the mix raw material tube 34 is removed from the Y-type mixer 57, the connection members 91 and 92 of the connection tool 67 are rotated in a direction away from the spring member 93, and the engagement portions 91D and 92D and the collar portion Release engagement with 97 and remove. Thereafter, the spring member 93 is removed from the connection tool 67, and the connection members 91 and 92 are rotated to remove the connection tool 67 from the mix raw material tube 34.

  And after taking out the mix raw material bag 5 from the bag case 31, the new mix raw material bag 5 is accommodated in the bag case 31, and it is set in the inside 2A similarly to the above, and the bag pressurizing pipe 7 and the mix raw material are used as described above. When the heat insulating door 3 is closed after the tube 34 is connected, the microcomputer 73 operates the air pump 27 again to increase the air pressure detected by the air circuit sensor 47 to the set value, To do.

  In addition, although the present Example demonstrates the case where two bag cases 31 which accommodated the mix raw material bag 5 in the cold storage 2 as mentioned above are arranged in parallel, in addition to this, the mix raw material is stored in the cold storage 2 The present invention can also be applied to the case where one bag case 31 containing the bag 5 is provided.

(6) Other Embodiments Related to Connector, etc. If the above-described connector 67 in the present invention is used, for example, a washer having a predetermined thickness between the Y-type mixer 57 and the engaging portions 91D and 92D of the connection members 91 and 92, etc. By interposing, the space between the sandwiching portions 91B and 92B can be expanded more than the above embodiment, and the passage area in the mix material tube 34 can be expanded. Thereby, since the passage area in the mix raw material tube 34 can be adjusted, the flow rate of the mix to the cooling cylinder 8 can be adjusted to be optimal in the frozen dessert manufacturing apparatus SM.

  Further, in the embodiment, the connecting device 67 is configured by the first and second connecting members 91 and 92 and the spring member 93 that are rotatably connected to each other. However, the first and second connecting members are not limited thereto. It is good also as a structure which separates and contacts in the state which 91 and 92 have faced. Also in this case, both connecting members are always urged toward the mixed material tube 34 by the spring member.

  Further, for example, the connector itself is made of a spring material (coil spring or the like), energized so as to sandwich the mixed material tube 34 at one end (becomes a sandwiching portion), and the Y-type mixer at the other end. It is good also as a structure engaged with 57 (it becomes an engaging part). With such a configuration, the structure can be significantly simplified. Furthermore, in the embodiment, the connector 67 is engaged with the Y-type mixer 57 that is a path component. For example, the air circuit 51 is connected to the cooling cylinder 8 at an inlet different from the mix material tube 34. In this case, the Y-type mixer 57 is not necessary. In that case, the mix inlet 9 of the embodiment is a path component, and the engaging portions 91D and 92D of the connector 67 are detachably engaged with the mix inlet 9 (in this case, a hook is formed). It will be.
