Description

[Detailed description of the invention] Industrial application field This invention relates to a sherbet-like food dispenser, and more specifically, it manufactures sherbet-like foods by stirring various beverages stored in a raw material tank while cooling them in a cooling chamber. The present invention relates to a dispenser for a sherbet-like food that can continuously extract the sherbet-like food in a cooling chamber in a good condition without melting it.

Prior Art Generally, various beverages are consumed in a liquid state, but this is processed into a sherbet-like food.
BACKGROUND ART Frozen luxury foods that can be scooped out and eaten with a spoon or the like are sold. Since the present invention relates to an improvement of a dispenser for processing this beverage into a sherbet-like favorite food, the basic structure of a typical dispenser will be explained before explaining the present invention to be described later.

FIG. 5 is an explanatory diagram showing the schematic structure of a conventionally known dispenser for shearbet-like food, in which an evaporation tube 12 led out from a refrigeration system (not shown) is wound around the outer periphery of a cylindrical cooling chamber 10. A stirring blade 16 is rotatably disposed inside the cooling chamber 10 via a rotating shaft 18, and is rotationally driven in a predetermined direction by a drive device (not shown). A pouring pot 14 is disposed at one end of the cooling chamber 10, and a pipe body 20 is led out from the other end and is connected to a raw material tank 22. A solenoid valve 24 is disposed in this pipe body 20, and this solenoid valve 24 is controlled to be open while the dispenser is in operation so that the cooling chamber 10 and the raw material tank 22 communicate with each other.

In addition, the raw material tank 22 and the gas cylinder 26 filled with compressed gas such as carbon dioxide are connected to the regulator 29.
They are connected to each other by a pipe body 28 having a pipe in the middle thereof. A desired beverage is stored in the raw material tank 22, and the internal pressure inside the tank 22 is increased by compressed gas supplied from the cylinder 26, and the beverage is transferred to the tube body 2.
0 to the cooling chamber 10.

Since the cooling chamber 10 is cooled by the operation of a refrigeration system, the beverage arriving through the pipe 20 is cooled to below freezing point in the cooling chamber 10, and the agitating blade 1
The beverage is then mixed with the beverage in a cooling chamber 10, and the mixture is processed into a shear vat of food. The gas pressure from which the beverage is pressurized is constantly applied to the cooling chamber 10, so that when a customer requests it, the shear vat of food can be poured out by opening a bucket 14.

Note that the cooling chamber 10 and raw material tank 22 are
Balance is maintained with constant pressure (approximately 1 Kg/cm ² ) applied at all times. Therefore, when the sherbet-like food is dispensed from the cooling chamber 10, the inside of the cooling chamber 10 becomes negative pressure, the pressure balance is disrupted, and the cooling chamber 10 is replenished with alcoholic beverage from the raw material tank 22.

However, in the above-mentioned dispenser, since the pressure of carbon dioxide gas is also used to extract the sherbet-like food from the cooling chamber 10, this carbon dioxide gas mixes into the obtained sherbet-like food, which may affect the taste when eating. It has a significant impact. In particular, when an alcoholic beverage such as Japanese sake is used as a raw material, it is empirically known that if carbon dioxide gas is mixed into the beverage, it becomes bitter and causes an undesirable change in taste. Therefore, attempts have been made to use nitrogen gas, which causes less change in flavor, in place of the carbon dioxide gas, but nitrogen gas is generally difficult to obtain and is expensive.

For this reason, as shown in FIG. 4, a soap dispenser-like food dispenser has been proposed that uses an air pump as a pressure source instead of using gas pressure such as carbon dioxide or nitrogen gas. In this system, a pipe body 20 connected to the discharge side of an air pump 32 is connected to the raw material tank 22 via a check valve 34, and the pressurized air from this air pump 32 is used to pump air into the raw material tank. 22 alcoholic beverages in cooling room 1
It is designed to force feed to 0. In addition, the pump 32
A sterilizer 36 consisting of a sterilization filter, an ultraviolet sterilizer, etc. is installed in the air suction pipe 32a, and after sterilizing and cleaning the air to be inhaled,
It is now being sent to 2.

Problems to be Solved by the Invention In the type of dispenser using the air pump described above, the pressurized air from the pump is used only for the purpose of pumping the beverage in the ingredient tank 22 into the cooling chamber 10. When the sherbet-like food is extracted from the cooling chamber 10, the amount of beverage reduced by the extraction is pumped from the raw material tank 22. At this time, the beverage in the raw material tank 22 is maintained at room temperature, so when the beverage is newly supplied to the cooling chamber 10, the temperature of the beverage replenished with the sherbet-like food stored in the cooling chamber 10 increases. It has the disadvantage of rapidly melting. Therefore, if the sherbet-like food produced in the cooling chamber 10 is
Even if it could be extracted several times, it could actually be extracted only about 10 times in good condition because it would melt due to the added drink. Therefore, when the solenoid valve 24 is closed to stop the supply of beverage to the cooling chamber 10, the pressure to extract the sherbet-like food in the cooling chamber 10 from the pot 14 is insufficient, and the extraction is interrupted midway. There is a problem with this.

Purpose of the invention The present invention was proposed in order to suitably solve the above-mentioned various drawbacks.It is an object of the present invention to continuously store sherbet-like food stored in a cooling chamber in a good condition without melting it. The purpose of the present invention is to provide a novel soap dispenser capable of dispensing food.

Means for Solving the Problems In order to overcome the above-mentioned problems and suitably achieve the intended purpose, the present invention provides a solution to the beverage stored in the raw material tank using pressurized gas supplied from a gas pressurization source. In a dispenser that is in pressure contact with a cooling chamber and processes the beverage into a sherbet-like food by cooling and stirring the beverage in the cooling chamber, pressurized gas from the gas pressurization source is transferred between the raw material tank and the cooling chamber. It is characterized in that it is configured so that it can be selectively switched and supplied to either one.

Embodiments Next, preferred embodiments of the soap dispenser-like food dispenser according to the present invention will be described below with reference to the accompanying drawings. Regarding the same members already shown in the conventional example explained in connection with FIG. 4,
They will be designated by the same reference numerals and detailed description thereof will be omitted.

FIG. 1 is an explanatory diagram showing a preferred embodiment of the soap dispenser-like food dispenser according to the present invention,
The basic arrangement members and their piping system are the same as shown in FIG. This dispenser uses an alcoholic beverage such as Japanese sake or whiskey as a beverage, and uses the aforementioned air pump 32 as a gas pressurization source. The pressurized gas from the air pump 32 can be selectively supplied to either the raw material tank 22 or the cooling chamber 10 using a switching valve. That is, the pipe body 3 that communicates and connects the air pump 32 and the raw material tank 22
A bypass pipe 38 is branched out from 0, and this bypass pipe 38 is connected to the pipe body 20 that connects the raw material tank 22 and the cooling chamber 10 in communication at a connecting portion 39 shown in the figure. At this time, an electromagnetically driven on-off valve 40 is interposed in the bypass pipe 38, and an electromagnetically driven on-off valve 24 is interposed between the connecting portion 39 of the pipe body 20 and the raw material tank 22. There is. Both on-off valves 40 and 24 are selectively switched so that their open and close states are reversed, thereby making it possible to selectively supply alcoholic beverages or pressurized air to the cooling chamber 10. There is. The reference numeral 41 indicates the cooling chamber 10 during cleaning work.
This shows the discharge valve used to completely discharge residual soapy food, alcoholic beverages, etc. from the machine.

FIG. 2 is a schematic diagram showing a soap dispenser according to another embodiment of the present invention, in which an air pump 32 is used as the gas pressurization source. A bypass pipe 38 is branched out from the pipe body 30 that communicates and connects the air pump 32 and the raw material tank 22.
The cooling chamber 10 is connected to a pipe body 20 that communicates with the cooling chamber 10 . At this time, an electromagnetically driven three-way switching valve 42 is provided at the connection between the bypass pipe 38 and the pipe body 20, and this three-way switching valve 42 is connected to the air pump 32.
The pressurized air from the raw material tank 22 and the cooling chamber 10
The switching operation is performed so that it can be selectively supplied to either one of the two.

Furthermore, in the basic configuration shown in FIG. 1, as shown in FIG. 3, a gas cylinder 26 filled with compressed gas such as carbon dioxide gas may be used instead of the air pump as the pressurized gas supply source.

Next, the operation of the shearbet-like food dispenser according to the present invention constructed as above will be explained. In the dispenser having the configuration shown in FIG.
When the dispenser is started, the solenoid valve 24 opens and the solenoid valve 40 closes, supplying pressurized air to the raw material tank 22 under the rotation of the air pump 32. Since the raw material tank 22 has a sealed structure, the pressurized air supplied to the tank 2
The internal pressure inside 2 increases. Therefore, the alcoholic beverage stored in the tank 22 is pumped into the cooling chamber 10 via the pipe body 20. Since a sterilization filter 36 is attached to the air suction pipe 32a of the air pump 32, clean pressurized air is always supplied to the raw material tank 22, and the raw material is not contaminated with bacteria, making it extremely hygienic. be.

Next, the alcoholic beverage supplied to the cooling chamber 10 is cooled in the cooling chamber 10 and stirred by a stirring blade 16 to be processed into a sherbet-like food product, which is stored in the cooling chamber 10 until it reaches its full capacity.

When extracting the sherbet-shaped food stored in the cooling chamber 10 from the container 14, in the embodiment shown in FIG.
The solenoid valve 24 provided in the bypass pipe 38 is closed, and the solenoid valve 40 provided in the bypass pipe 38 is opened. As a result, the pressurized air supplied from the air pump 32 is delivered to the cooling chamber 10 without passing through the raw material tank 22.
supplied directly to Therefore, the internal pressure of the cooling chamber 10 does not decrease, and even if the sherbet-like food is stored in the cooling chamber 10 at its maximum capacity, all of it can be extracted continuously. Moreover, when the food is extracted, the solenoid valve 24 closes to stop the supply of alcoholic beverage from the raw material tank 22, so the sherbet-like food stored in the cooling chamber 10 is not melted, and the best cooling is always achieved. extraction in the state can be achieved.

When the brewing is finished, the pot 14 is closed, but if you do not want to resume brewing the beverage immediately, reverse the switch mechanism (not shown) to close the solenoid valve 24.
At the same time, the solenoid valve 40 is closed. As a result, the alcoholic beverage reduced by the extraction is supplied to the cooling chamber 10, where it is cooled and stirred, and processed into a sherbet-like food again.
It is stored in 0.

Further, in the embodiment shown in FIG. 3, only the gas cylinder 26 is used as the gas pressurization source, and other configurations and switching operations of the valve bodies 24 and 40 are the same as in the first embodiment. Furthermore, in the embodiment shown in FIG. 2, by switching the three-way switching valve 42, alcoholic beverages or pressurized air can be selectively supplied to the cooling chamber 10 as required. Although a solenoid valve is used in the embodiment, it goes without saying that a manually operated on-off valve may also be used.

Effects of the Invention According to the shearbet-like food dispenser of the present invention configured as described above, pressurized gas can be directly supplied to the cooling chamber without passing through the raw material tank by providing a bypass pipe, so that the pressurized gas is stored in the cooling chamber. It is possible to extract all the products continuously. Furthermore, since the beverage is not replenished from the raw material tank during extraction, the sherbet-like food in the cooling chamber does not melt, and the beverage can always be extracted in the best condition.
Furthermore, when cleaning the inside of the cooling chamber, pressurized gas can be directly supplied to the cooling chamber via the bypass pipe, so
This provides beneficial effects such as the ability to quickly discharge products remaining in the cooling chamber to the outside of the machine.
