Abstract

PURPOSE:To make washing of a transit tank possible arbitrarily even during preparation of product, letting the first discharge valve be in a closed state and the second discharge valve in an open state in a washing condition, spraying water supplied from a water feed pipe upon the float face in the transit tank. CONSTITUTION:A dispenser is equipped with the syrup feed pipe 7a attached to the top plate 5d of the transit tank 5, the carbonic acid feed pipe 1a, the water feed pipe 13a, the mixed solution feed pipe 16 to communicate the transit tank 5 to transport the mixed solution with a cooling chamber, the first and the second discharge valves 17 and 21 connected to the feed pipe 16. Namely, the valve 17 is in open state and the valve 21 is in closed state in a condition of product preparation, water sent from the water feed pipe 1a is sprayed upon the face of float 5b, and the interior of the transit tank 5 is washed. Even during product preparation, the transit tank can be thus washed arbitrarily and easily.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to frozen carbonated beverage dispensers, and more particularly to cleaning of relay tanks.

In conventionally used dispensers of this type, the relay tank contains a mixture of syrup, water and carbon dioxide gas.

For hygiene reasons, it was necessary to wash it arbitrarily.

It was impossible to clean the relay tank during product manufacturing.

It is an object of the present invention to provide extremely effective means for quickly eliminating the above-mentioned drawbacks. In particular, it is an object of the present invention to provide a first In the product manufacturing state, the first discharge valve is open and the second discharge valve is closed, and in the cleaning state, the first discharge valve is closed and the second discharge valve is open. In addition, it is characterized by a structure in which the inside of the relay tank is cleaned by spraying water supplied from the water supply pipe 1 onto the float surface inside the relay tank.

Hereinafter, preferred embodiments of the frozen carbonated beverage dispenser according to the present invention will be described in detail with reference to the drawings.

FIG. 7 shows a schematic system diagram of the entire frozen carbonated beverage dispenser according to the present invention, in which carbon dioxide gas from the carbon dioxide pump l is supplied to a carbon dioxide gas supply pipe/a including a first regulation valve, a first t magnetic valve 3, and a first regulation valve. At the same time, the carbon dioxide gas supply pipe /a is connected to the syrup tank S via the branch pipe A1 at the first branch part 6.

The syrup in the syrup tank is pumped through the second solenoid valve g and the first check valve 9 by the pressure of the carbon dioxide gas supplied as described above.
Syrup supply pipe with? The water in the water storage tank 13 is supplied to the relay tank S via a water supply pipe/3FL having a third check valve/Q, a third reginulator// and a pump motor saw. is supplied.

A pressure switch /4t is connected to the carbon dioxide gas supply pipe 〆a, and a mixed liquid supply pipe 16 is connected to the discharge port IS opened in the bottom plate ia of the relay tank S, and the mixed liquid supply pipe /A is connected to the 1 discharge valve l? It is connected to the bottom plate /q of cooling chamber /1 via. Further, a second discharge valve 2/ is connected to the second branch part λθ of the mixed liquid supply pipe /A, and an outlet 0.2/a of the first discharge valve / is open to the atmosphere, and the cooling chamber /
A spout valve 2.2 for taking out the product is provided on the side of g.

Furthermore, Fig. 2 is an enlarged sectional view of the relay tank j, and there is a flow inside the relay tank S with a diameter slightly smaller than its inner diameter.
yb is built-in in a state floating on the mixed liquid sC, and the tip of the water supply pipe /Ja protrudes into the upper plate ya of the relay tank 5, and the injection port /? b, and the first check valve 9 is disposed between the syrup supply pipe a and the upper plate 5d.

In the above configuration, when operating the frozen carbonated beverage dispenser according to the present invention, first, in the product manufacturing state, the first
When the discharge valve 17 is kept open and the first discharge valve /2/ is kept closed, the mixed liquid in the relay tank S is supplied to the cooling chamber /g by the carbon dioxide gas pressure from the carbon dioxide gas cylinder 1.

When switching to the cleaning state, the first discharge valve is kept closed and the first discharge valve is opened, the first solenoid valve 3 is closed to stop the supply of syrup, and the water storage tank is opened. After supplying water to 3, when the pump motor 2 is operated, the water in the water storage tank 3 is injected as cleaning water onto the surface of the flow 1-sb section from the injection port 3a through the water supply pipe 3eL,
The water is reflected on the upper surface of the float and splashed on the upper inner surface of the relay tank 5.

The inside of the relay tank j is cleaned, and the water after cleaning is sent to the first discharge valve/
1 and then discharged to the outside. in this case.

1st discharge valve/? is in a closed state, no washing water is supplied into the product in the cooling chamber 1g, and the first check valve 9 prevents washing water from flowing back into the syrup supply pipe ta.

Further, since the carbon dioxide gas supply pipe /a is supplied with carbon dioxide gas from the carbon dioxide gas cylinder 1 under pressure, cleaning water will not flow back into the carbon dioxide gas cylinder 1.

A frozen carbonated beverage dispenser according to the invention.

With the above configuration and operation, the relay tank can be easily cleaned at any time even during product manufacturing. Furthermore, the interior of the relay tank can be cleaned by stopping the supply of syrup and supplying water from the water storage tank as cleaning water. Furthermore, the first check valve installed in the syrup supply pipe allows the relay tank to be cleaned without discharging the syrup in the syrup supply pipe, and the cleaning operation is controlled only by the first and second discharge valves. This has the advantage of being easy to perform.
