Description

[Detailed description of the invention] This invention is designed to appropriately supply the mix stored in a mix tank into a freezing cylinder connected to a freezing system, and take out the soft serve ice cream produced in the freezing cylinder to the outside by operating a takeout device. In particular, the present invention provides a soft serve ice cream making machine equipped with a device for early detection of insufficient mix and a device for notifying a user of the insufficient mix state.

An embodiment of the present invention will be described below based on the drawings.

1 is a mix tank that stores the so-called mix that is the raw material for soft-serve ice cream; 2 is a refrigeration cylinder that is a chamber for producing soft-serve ice cream; A cylinder cooling vibro is wound around the mix tank 1 through a cooling valve 5, and a tank cooling pipe 8 is wound around the mix tank 1 through an electric compressor 3, a condenser 4, and a second cooling pulp 7. .

9 is a thermostatic type first sensor in which a temperature sensing part 9A is arranged to detect the state (temperature) of the soft serve ice cream by the temperature of the freezing cylinder 2, which is separated from the cylinder cooling vibro so as not to be affected by the evaporation temperature. The cooling device controls the first cooling pulp 5 to control ON-OFF of the cooling operation of the freezing cylinder 2.

Reference numeral 10 denotes a second temperature sensing device of a thermostatic type that detects the evaporation temperature by bringing the temperature sensing portion 10A into contact with the outlet portion of the cylinder cooling vibro, and is set at a lower temperature than the first temperature sensing device 9.

11 is a hopper thermostat that detects the temperature of the □Tx tank 1 and controls the second cooling valve 7;
Set the temperature sensing device 9 to a high temperature and peel.

In addition, 12 is a refrigeration cylinder 2 containing air.
Mix feeder I3 is the refrigeration cylinder 2.
I4 is the stirring device 1 which appropriately stirs the mix cooled in the interior and serves as a delivery mechanism when supplying the product.
This is the driving electric motor of No. 3.

Further, on the front surface of the freezing cylinder 2, there is a plunger 1 for communicating and cutting off the inside of the freezing cylinder 2 and the supply port 15.
6A and a lever 16B for operating the plunger 16A.

Next, the electric circuit of the present invention will be explained.

17 is an operation switch, 9 is the first temperature sensing device having a high temperature side contact 9a and a low temperature side contact 9b, and the second temperature sensing device having a high temperature side contact 10a and a low temperature side contact 10b on the power supply side
temperature sensing device 10 is connected.

Further, a mix insufficient alarm lamp 18 is connected to the low temperature side contact 10b of the second temperature sensing device port 0.

3 is the electric compressor, I9 is an air cooling fan for the condenser 4,
5 is the first cooling valve, If is the hopper thermostat, and 7 is the second cooling valve.

Further, reference numeral 14 denotes a supply switch whose contact point can be switched by operating the lever 16B of the take-out device 16, and the electric motor 20 for driving the stirring device 13 is operated.

Next, the operation of the present invention will be explained based on the above configuration and electric circuit.

First, a description will be given of the operation starting state in which the mix is filled in the freezing cylinder 2 and the mix is sufficiently stored in the mix tank 1.

In this state, when the - switch 17 is turned on, the electric compressor 3 and the 1 cooling valve 5, fan 19, and Horaparther Mostara [
1, the second cooling valve 7 is operated, and cooling operation of the freezing cylinder 2 and the mix tank 1 is started.

The stirring device 13 also operates.

Thus, the mix in the freezing cylinder 2 is cooled and stirred to produce soft serve ice cream.

As this cooling operation progresses, the i-th temperature sensing device 9, which detects the state of the soft serve ice cream based on the temperature of the freezing cylinder 2, detects a predetermined temperature at which the cooling operation is turned off, and switches its contact from the high temperature side contact 9a to the low temperature side contact 9a. In order to switch to the side contact 9b, the electric compressor 3, fan 19, first cooling valve 5, and second cooling valve 7 are made inoperable.

Button Even when the first temperature sensing device 9 is located at the high temperature side contact 9a, the second cooling valve 7
ON-OFF control is performed as appropriate by l.

By the way, if there is no shortage of mix in the refrigeration cylinder 2, the refrigeration load is sufficient, so the evaporation temperature does not drop at the predetermined temperature 1, and the second temperature sensing device 10 moves from the high temperature side contact 10a to the low temperature side contact 10b. It never switches to .

Therefore, the normal cooling operation is controlled by the i-th temperature sensing device 9 to maintain the temperature of the soft serve ice cream well within a predetermined range.

However, as the external supply of soft-serve ice cream is repeated over and over again, the mix in the mix tank gradually decreases and eventually becomes empty.

If soft serve ice cream is further supplied externally in this state, the mix will be completely insufficient.

Then, as the refrigeration load, that is, the amount of soft-serve ice cream, decreases, the temperature of the soft-serve ice cream decreases, and as a result, the evaporation pressure decreases, and the evaporation temperature suddenly decreases, unlike in the normal case, and the first temperature-sensing device 9 detects the temperature at which FF is to be turned on during cooling operation (1), the second temperature sensing device 10 detects a predetermined decrease in the evaporation temperature, and switches its contact from the high temperature side contact 10a to the low temperature side contact 10b.

As a result of this switching, the insufficient mix notification lamp 18 lights up to notify the user of the insufficient mix.

Then, if the user replenishes the mix based on this notification, normal operation will be resumed.

FIG. 3 shows the temperature-sensing characteristics of the first and second temperature-sensing devices 9 and 10 in the regressive state and in the □x shortage state described above.

As described above, the present invention includes a first temperature-sensing device that detects the state of the soft-serve ice cream based on the temperature of the freezing cylinder and controls ON/OFF of the cooling operation, and a temperature-sensing device that detects the state of the soft-serve ice cream based on the temperature of the freezing cylinder.
The second temperature sensing device detects the evaporation temperature of the refrigeration system at a temperature lower than that of the temperature sensing device, and the mix shortage alarm device, and the second temperature sensing device detects the low temperature side setting value. Since the notification device is activated when this happens, the user does not have to pay attention to the state of remaining mix in the mix tank, and can use the operation of the notification device as a guide for replenishing the mix. There is no need to continue operation, and the mix can be replenished before machine trouble occurs, which is an extremely advantageous advantage.

1 detects a lack of mix by temperature, but normally the notification device will not operate if there is enough mix.When there is a lack of mix, the second temperature sensing device can detect this early and reliably. Playing with multiple advantages.
