Next, the present invention will be explained in detail based on the above configuration. First, with power applied to the entire system, turn on the pump device (
17) is activated, the mix in the mix tank (1) is sucked in through the suction pipe (18), and at this time the air introduction pipe (2
1) Mix supply pipe (
19) and is supplied to the cooling chamber (5) from the rear inlet (5A) of the cooling chamber (5). When a predetermined amount of the mix is completely supplied to the cooling chamber (5), the pump device (17) is stopped to end the supply of the mix.

Thereafter, when the mix supplied to the cooling chamber (5) is cooled by circulating low-temperature refrigerant gas through the evaporation pipes (31) and (39), the mix gradually increases its viscosity and becomes semi-frozen. Finished as an ice cream shake.

Next, the operation of taking out the ice cream shake that is finally made by mixing the shake base finished in the cooling chamber (5) as described above and the syrup will be explained below. If you want a cream shake, for example, press the switch labeled "Chocolate" and the solenoid device (9) as shown in Fig.
1) is fully excited, the plunger (91A) is attracted, and the operating pin (90) pulls the lever (89) forward. Then, the lever (89) rotates about the fulcrum (88) and moves the operating rod (87) toward the cooling chamber (5). This movement of the operating rod (87) pushes the valve (83) backward against the coil spring (85) to open the side hole (80). As a result, the shake base in the cooling chamber (5) is moved from the outlet (81) to the side hole (80) by the stirrer (68).
) to the mixing chamber (93). At the same time,
When the syrup supply solenoid valve (15A) opens, the gas phase pipe (9)
, syrup tank (3) via syrup suppression pipe (12A)
A) The pressure of the compressed gas applied to the tank (
The chocolate syrup in 3A) is fed to the syrup supply pipe (1
4A), the nozzle (14A2) via the transparent tube (14A1)
) to the mixing chamber (93).

In this way, the shake base and chocolate syrup supplied to the mixing chamber (93) are stirred and mixed at an extremely high speed by the stirring blade (94) linked to the drive motor to form a chocolate-flavored ice cream shake, which is then taken out. It can be extracted continuously from the spout (93A) to the cup (69).

Therefore, the extraction of ice cream shake can be stopped due to switch operation, measurement, time, etc., but in any case, when stop No. 2 is issued, first the syrup supply solenoid valve (15A) is closed and the mixing chamber (15A) is closed. Stop feeding chocolate syrup to 93). Subsequently, the excitation to the solenoid device (91) is completely released and the lever (89) returns to its normal position as shown in Fig. 3 by the action of the return spring (92), and the operating rod (87) follows this. Return to forward position. As a result, the valve (83) is completely pressed against the step (86) of the side hole (80) by the coil spring (85), closing the side hole (80).

The above describes the operation for taking out a chocolate-flavored ice cream shake, but if you want a strawberry-flavored ice cream shake, the syrup supply solenoid valve (15B) is opened and a vanilla-flavored ice cream shake is produced. Syrup supply solenoid valve (15C) if desired
is opened, and if a yogurt-flavored ice cream shake is desired, the syrup supply solenoid valve (15D) can be opened by operating the corresponding switch.

In the above-described take-out operation, when the shake base in the cooling chamber (5) is sent to the mixing chamber (93), the pressure detection device (20) detects the pressure drop in the cooling chamber (5), and the pump device detects the pressure drop in the cooling chamber (5). (17) to supply the mix to the cooling chamber (5).

Next, the cleaning work and operation of the present invention will be explained. First, the syrup supply pipe (1
4A), transparent tube (14A1>, syrup supply tube (14B)
) and the transparent tube (14B1), the syrup supply tube (14C) and the transparent tube (14C1), and the syrup supply tube (14D) and the transparent tube (14D1). Also, remove the rotating shaft (96) and install the stirring blade (94) into the mixing chamber (93).
) and then remove the sliding bearing (95). These removed parts are cleaned and stored separately.

After that, as shown in Fig. 9 and No. 101m, the transparent tube (
Connectors (14A1) to (14D1> prepared with self-sealing couplings (14A3) to (14D3) at the ends
Self-sealing coupling (23A2) provided on the outlet side of 23)
) to (23D2), and further connect to the connector (23D2).
Connect the self-sealing coupling (112A) provided at the end of the connecting pipe (112) extending from the inlet side of the hot water supply pipe (2) to the hot water supply pipe (2).
Self-sealing coupling (22A1>) provided at the end of 2A)
Connect to. At the outlet of the mixing chamber (93), there is a small-diameter hot water discharge passage (2) that communicates the inside and outside of the mixing chamber (93).
Attach the cap (235) formed with 34).

After completing the above operations, when the switch (113) is pressed, an output pulse is generated from the switch circuit (114) and input to the input port (Do) of the latch circuit (117).
From the output port (Q,) of the latch circuit (117) to “H4
can be output. As a result, the r L J level signal is input to the timer circuits (119) and (135), and the timer circuits (119) and (135) start low.
The timer circuit <135) repeatedly outputs 'HJ for 14 hours (30 seconds) and T1 time (3 minutes) as described above. The output of this timer circuit (135) and the latch circuit (117)
The output of the AND circuit (136) which inputs the outputs of the output ports (Q,) respectively becomes an output synchronized with the timer circuit (135). Therefore, now from the AND circuit (136) rH
, is output, the transistor (13B> is ONL, , the first relay (139) is energized via the OR circuit (137), the normally open contact (139A) is closed, and the hot water supply solenoid valve (
24) opens.

This allows the heating vibrator (10
3) The tap water passes through the flow switch <108) is ON.
A sheathed heater (102
), then passes through the hot water supply pipe (22A), through the connecting pipe (112), through the connector (23), and through the transparent pipes <14A1), (14B1), (14C1) and (14D1>). Through each nozzle (14A2), (14
B2), (14C2) and (14D2) to the mixing chamber (9
3) released within. The hot water completely discharged into the mixing chamber (93) cleans and sterilizes the mixing chamber (93), and then closes the cap (2).
The hot water is drained from the drainage passageway (234) of 35) to a suitable drain means, but because this passageway (234) is narrow, the hot water is sufficiently grooved into the mixing chamber (93) and is drained from the upper end opening of the vertical hole (79). Also, the mixing chamber (93), the vertical hole (79), and even the valve (83) will overflow.
The horizontal hole (80) up to the side hole (80) is thoroughly cleaned and sterilized.

On the other hand, the hot water supply temperature is controlled to be constant based on the hot water temperature sensor (109), and the hot water temperature setting temperature (in the example is 75
℃ setting), the output voltage of the amplifier (140> becomes lower than the negative input voltage of the comparator (141), and the output of the comparator (141> becomes "L"). This output and the time at T1 are outputted as H. AND circuit (136
The output of the AND circuit (142) which inputs the outputs of
The light receiving element (143B) is 0FFt.

This turns on the transistor (144), which turns the SIRISK (145) and further the TRIAC (147) to 0FFL, and turns off the sheathed heater (102). When the water temperature drops slightly below the set temperature again, the amplifier (140)
The output voltage of the comparator (141) becomes higher than the negative input voltage of the comparator (141), and the output of the comparator (141) becomes “H”.
”. Since the output of the AND circuit (142) which inputs this output and the output of the AND circuit (136) becomes "H", the light emitting element <143A) emits light and the light receiving element (143A) emits light.
3B> turns on and turns off the transistor (144),
As a result, Cyrisk (145), Triac (14)
7) is turned on in sequence, and the sheathed heater (102> is turned on.) In this way, the hot water supply temperature can be controlled to a substantially constant temperature suitable for cleaning and sterilization.

Then, when 12 hours have passed and the output of the AND circuit (136) becomes rL at time T, the output of the AND circuit (14
2) output becomes rL, and at this point the sheathed heater (
102) is 0FFt, this heater (102) is OFF
lasts for 18 hours. Also, the output of the OR circuit (137) is r
L, turning off the transistor (138), thereby de-energizing the first relay (139), opening the normally open contact (139A), and closing the hot water supply solenoid valve (24). Such a delay in the hot water supply solenoid valve (24) is caused by the heater (
The water heated by the residual heat of the mixing chamber (9) turns into steam.
It is effective in preventing the danger of being sent to 3).

The cleaning time is controlled by a timer circuit (119), and when a predetermined time elapses after the timer circuit (119) starts, the timer circuit (119) starts r
It generates the output of H, and inputs it to the input capo-1-(D,). As a result, the output of the output boat (Q,) becomes rL, the timer circuit (119) is reset, and the cleaning circuit ends its operation. Strictly speaking, the output boat (Q6)
When the delay time by the integrating circuit (149) in the cleaning circuit has elapsed after the output of the cleaning circuit becomes r L , the cleaning circuit completely ends its operation.

Therefore, it is desirable that the user can confirm the completion of the cleaning operation using an LED, a buzzer, etc. When the cleaning operation is completed, the state of piping connections for cleaning shown in Figures 9 and 10 should be changed. Perform the work to return to the normal piping connection state shown in Figures 2 and 3. First, disconnect the connecting pipe (112) and hot water supply pipe (22A), and then
), (14B1), (14C1), and (14D1) and the connector (23), then remove the transparent tube (14A1) from the connector (23).
) to (14D1) again to the syrup supply pipe (14A),
Connect to (14B), (14C) and (14D). Furthermore, the cap (235) was removed and the previously stored plain bearing (95) was attached, and the stirring blade (94) was inserted into the mixing chamber (93).
) and insert the rotary shaft (96) into the cable (9
8).

By completing the work to the north, it will be possible to take out the ice cream shake again, but the mix in the cooling chamber (5) will be notified by means such as an LED or a buzzer that the temperature has dropped to the ideal takeout temperature due to the cooling operation. It is desirable that the user be able to confirm this by

The hot water supply device of the present invention may be of a hot water storage type in addition to the instant water heating type described in the embodiments.

The above-described cleaning device for a frozen dessert manufacturing device of the present invention has been explained using an ice cream shake manufacturing device as an example, but the present invention can also be applied to a cleaning device similar to an ice cream shake, such as a soft ice cream shaker, without departing from the spirit of the present invention. It can also be applied to equipment for producing creams and the like.

(G) Effects of the Invention As described above, the present invention is advantageous in that hot water is supplied from the water heater through the passage in the take-out device from the opening/closing means to the take-out port without recovering the mix that has been cooled in the cooling chamber. This provides an excellent advantage in that it can be cleaned and sterilized quickly, and the take-out section of the take-out device, which is most important in terms of hygiene management, can be hygienically managed.

In addition, the present invention can effectively clean and sterilize the semi-frozen mix and syrup mixing chamber defined in a part of the passage, and furthermore, from the syrup supply pipe to the nozzle tip. This has the advantage of preventing clogging of syrup with high sugar content.
