[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a diluted dessert base using a liquid level detection sensor and a frozen dessert base supply mechanism operated by an output signal of the liquid level detection sensor. A frozen dessert manufacturing apparatus for storing a frozen dessert base in a tank while maintaining the liquid level, and for stirring the frozen dessert base in the freezing region while freezing the stored dessert base to supply solid dessert frozen dessert. The mechanism includes a control valve for supplying a confectionery base to the confectionery machine operated by the detection signal of the liquid level detection sensor, a syrup supply mechanism that operates in synchronization with the control valve, and a pressure fluctuation of the water supply piping system. A water supply mechanism that operates correspondingly, and a mixer that dilutes and adjusts the supplied syrup with water, and the mixer passes water from a small-diameter path to a large-diameter path. The syrup was extracted by vacuum phenomenon occurring during, the syrup is had adopted a configuration formed by employing a mechanism for dilution prepared above water.

In the present invention configured as described above,
The liquid level of the frozen dessert base stored in the tank is detected by a liquid level detection sensor, and based on the detection, syrup and water are automatically supplied, and they are mixed by a mixer.
The dilution is adjusted to a certain concentration, and the frozen dessert base is automatically supplied to the tank to maintain the liquid level. That is,
A frozen dessert base having a constant concentration can be obtained without the need for a metering pump, and the liquid level of the frozen dessert base is maintained.

[0007]

Next, a first embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a frozen dessert making machine, and a compressor and a condenser (not shown) are provided at a base portion thereof.
, And there is a frozen dessert-based tank 2 at the top.
In the lower part of the tank 2, a refrigeration zone 3 is formed by making the evaporator of the refrigeration cycle into a cylindrical shape. This frozen area 3
Inside and outside are internal stirring blades 4i as shown in FIGS.
And an external stirring blade 4o.

[0008] Behind the freezing area 3, the frozen dessert base stored in the tank 2 can flow into the freezing area 3. Inside the tank 2, a liquid level detection sensor 5 based on a frozen dessert and a water level detection sensor 6 which also performs level detection of an abnormal liquid level and a washing water level are installed. The detection level of the water level detection sensor 6 is based on the frozen dessert-based liquid level detection sensor 5.
In this embodiment, the supply port 24 (FIG. 5) of the frozen dessert base is opened between the installation levels of the two sensors. This is supply port 2
When the electromagnetic valve for opening / closing 4 is closed, the frozen dessert base remaining in the supply port 24 is taken into consideration so as not to freeze.
If a heater is attached to the supply port 24, the supply port 24 can be opened near the freezing area.

In front of the frozen dessert production machine 1, a dessert supply cock 7 is provided at the front end of the frozen area 3, and its handle 8
, The frozen dessert is supplied to the cup C. A connection port is provided on the back surface of the frozen dessert production machine 1, and a frozen dessert base supply pipe is connected by a pipe joint.

A portion surrounded by a two-dot chain line in the center of FIGS. 1 and 2 is a frozen dessert base supply mechanism 10 for supplying a syrup supply system 11, a water supply system 12, and a syrup with water at a predetermined concentration. It comprises a diluted dessert-based supply system 13.

The syrup supply system 11 includes a frozen dessert production device 1b.
A connection pipe 15 extending from a syrup tank 14 disposed outside the pipe is connected by a pipe joint 16, and reaches a dilution regulator 20 via a syrup solenoid valve 17, a pressure regulator 18 and a check valve 19. The syrup tank 14 is connected to a carbon dioxide gas cylinder b by a connection pipe 15b so that a constant pressure is applied to the syrup tank 14 to feed the syrup under pressure. A syrup sensor 26 is attached to the outlet of the syrup tank 14 (may be inside the frozen dessert production device 1b).

In the water supply system 12, a water purifier S is provided inside (or outside) the frozen dessert manufacturing apparatus 1b, a connecting pipe 15a extending therefrom is connected by a pipe joint 16a, a water solenoid valve 17a and a pressure reducing valve 21. , The demand pump 22, the pressure regulator 18a and the check valve 19a to reach the dilution regulator 20. In FIGS. 1 and 2, the position of the water solenoid valve 17a is back and forth, but there is no functional change.

The frozen dessert base supply system 13 includes a dilution adjuster 20.
, The dilution regulator 20 is provided with a water flow path on the same axis as shown in FIG. 3, the upstream flow path Q is reduced in diameter, The side q has a large diameter, and a connection (a so-called Venturi mechanism) is used in which a syrup pipe is opened at this position by utilizing a decompression phenomenon generated at a boundary between the small diameter flow path and the large diameter flow path.

The diluted dessert base is supplied to the dessert production mechanism 1 through the piping 23 of the dessert base supply system 13. A solenoid valve 25 is provided at the pipe connection portion 16b of the frozen dessert production mechanism 1.
Is provided, and is operated by an output signal of the liquid level detection sensor 5 of the tank 2.

Next, the operation of the present invention will be described.
When the liquid level of the frozen dessert base in the tank 2 drops, the liquid level detection sensor 5 operates, and the electromagnetic valve 25 provided at the connection port P on the back side of the body of the frozen dessert production mechanism 1 opens. At this time, the demand pump 22 is reduced in pressure at its discharge port, the demand pump 22 is started and water is supplied, and when the water passes through the venturi mechanism, the syrup is supplied at a fixed ratio and adjusted for dilution. It is supplied to the tank 2 as a frozen dessert base. At this time, the frozen dessert base may be supplied intermittently.

Conversely, when the liquid level rises and the liquid level detection sensor 5 detects this, the solenoid valve 25 of the connection port P closes and the supply of the frozen dessert base is cut off.
The pressure at the discharge port increases and stops, and the function of the syrup supply system 11 also stops.

On the other hand, when the syrup tank 14 becomes empty and syrup is not supplied, the syrup sensor (capacitive sensor) 26 is activated, and the solenoid valve 25 of the connection port P is operated.
Closes, preventing the supply of syrup-free frozen dessert base. When the replacement of the syrup cylinder 14 is completed, the transmission of the syrup sensor 26 stops (turns off), the electromagnetic valve of the connection port P opens, and the supply of the frozen dessert base is restarted.

[0018]

As described above, according to the present invention,
Since the frozen dessert base can be automatically replenished to the tank of the frozen dessert production department, labor can be saved, and the frozen dessert base having a predetermined concentration can be replenished.
