Description

[Detailed Description of the Invention] a. Field of Industrial Application The invention relates to a frozen carbonated beverage dispenser, particularly for cooling a mixed liquid in a relay tank to improve carbonation and reduce product manufacturing time in a cooling chamber. This relates to improvements to shorten the time.

b. Conventional technology This type of dispenser that has been used in the past has two methods: supplying syrup, water, and carbon dioxide directly into a relay tank and making a mixture in the relay tank, and one method that supplies syrup and water directly to a relay tank. A typical configuration was one in which the mixed liquid and carbon dioxide gas were mixed immediately before being fed into a relay tank.

C0 Problems to be Solved by the Invention In the conventional configuration described above, when the temperature of the water supplied to the relay tank rises, due to the characteristics of carbon dioxide gas, the amount of water dissolved decreases, that is, force-ponation occurs. becomes worse,
It was necessary to change the carbon dioxide pressure in response to changes in water temperature. In addition, water temperature is generally 25°C in the summer for water supplies, but these days, water storage tanks are often installed on the roofs of buildings, and the temperature can rise to 10°C to 25°C in the summer. Furthermore, in some areas in the southern region, the temperature of the supplied water rises to nearly θ℃.

As mentioned above, when the carbonation deteriorates, the finished product lacks the refreshing feeling of carbonic acid and has little buildup, resulting in a heavy and damp product that is otherwise undesirable.

Furthermore, as the water temperature rises, the temperature of the replenishment liquid mixture to the cooling chamber also rises, which takes an extremely long time to cool the products in the cooling chamber, resulting in a reduction in manufacturing capacity.

d. Means for solving the problems The purpose of the present invention is to provide extremely effective means for quickly eliminating the above-mentioned drawbacks.
The gist of this is that syrup, water, and carbon dioxide gas are supplied to a relay tank, and a mixed liquid of these is supplied to a cooling room to produce a frozen carbonated drink. 1 evaporation tube.

a second evaporation tube provided in the cooling chamber; a refrigeration device connected to the evaporation tube; first and second control valves provided between the refrigeration device and each evaporation tube; Frozen carbonic acid comprising: a temperature detection device provided in the relay tank; a refrigeration control device provided in the cooling chamber; and a refrigeration control circuit connected to each of the temperature detection devices, the refrigeration device, and each control valve. A beverage dispenser.

00 action The refrigeration control device and temperature detection device installed in the cooling room and relay tank detect the temperature or torque of the mixed liquid in the cooling room and relay tank, and each evaporator installed in the cooling room and relay tank In addition to controlling the supply of refrigerant to the pipes, the flow of refrigerant is also controlled to keep the mixed liquid in the relay tank cool at about 7θ° C. or below so that it does not freeze.

In addition, since the mixed liquid in the relay tank is kept cool in the above-mentioned state, the cooling time of the product in the cooling room is shortened, and the carbonation can be polished well and stably.

F. EXAMPLES A preferred embodiment of the frozen carbonated beverage dispenser according to the invention will now be described in detail with reference to the drawings.

What is indicated by the symbol / in FIG. 1 is a carbon dioxide gas cylinder filled with carbon dioxide gas. is connected to the carbon dioxide gas port 6a of the relay tank B, and the first connecting means 7 provided at the first branch portion 5a provided at the first connecting means is connected to the syrup tank g.

A third connecting means // provided in the syrup tank g and having a third regulator and a second solenoid valve /θ is connected to the syrup port 6b of the relay tank B, is connected to the water storage tank saw, and is connected to the pump /, 3. Connection means/6 having M'l regulator/41 and reversal valve/2
is connected to the water inlet 6C of the relay tank B.

A pressure switch /7 as a safety device is connected to the first branch part 5b of the first connection means 5 connected to the relay tank B, and a cooling chamber co0 having a pouring cock /g and a valve /9 is connected. The communication pipe 2/ connected to the bottom 20h is connected to the bottom 4d of the relay tank B.

Next, the configuration shown in FIG. 1 is such that the relay tank 6 and cooling chamber 3 in FIG. , the first evaporation tube 22 is provided in a wound manner, and a heat insulating material 23 is formed over the entire surface thereof. Inside the relay tanker, a float for gas-liquid separation is provided floating above the mixed liquid 6e, and a temperature detection device 25 is attached to the bottom of the float to detect the temperature of the mixed liquid 6e. Temperature is detected indirectly. A second evaporation tube roller is wound around the outside of the cooling chamber 20, and the bottom 2
A refrigeration control device 27 is attached to 9IL and indirectly detects the temperature of the product to be frozen. It should be noted that, although a temperature sensing type is most suitable for this refrigeration control device =7, the same effect can be obtained even if it is of a torque sensing type or the like.

Further, the discharge section 28a of the refrigeration system, which is made up of a compressor or the like indicated by the symbol -g, is connected to the input section of the evaporator f2 by a fifth connecting means 3o having a first control valve 9. The sixth connecting means 31 connected to the third branch JOa of the fifth connecting means 3θ is connected to the inlet part of the first evaporation pipe 22 via the second control box JltL. There is.

The first connecting means 32 connected to the outlet section b of the first evaporator tube B is connected to the suction section col lb of the refrigeration device 28, and is connected to the outlet section 22b of the first evaporator tube λ. The g-th connecting means J, 7 is connected to the second branch 32a of the three first connecting means ε. , which returns to the 2nd floor. In other words, the refrigerant condensed in the refrigeration system -g is branched by the third branch part, )OeL, and the refrigerant that has passed through the first control valve λ9 is evaporated in the second evaporation pipe 26, and the mixed liquid in the cooling chamber co0 is is frozen. Further, the refrigerant 1 that has passed through the first control valve 31a is evaporated in the first evaporation pipe 22, cooling the mixed liquid in the relay tank 6, and the temperature detection device 2 prevents the mixed liquid 6e in the relay tank 6 from freezing. As such, the second control valve JI& and the refrigeration device 28 are controlled by the refrigeration control circuit section j4t, which will be described later.

The refrigeration control circuit section 3da is configured as shown in FIG.
The temperature sensing device S is connected in series to the second relay X2, and the normally open contacts x1 and xH are connected in series to the first and first control valves 9 and 3ih, respectively. Normally open contacts x13 and x,3 are connected in series to the refrigeration device λg.

Next, a case will be described in which the frozen carbonated beverage dispenser according to the present invention configured as described above is operated.

In the state shown in FIG. 3, the mixed liquid at room temperature is supplied to the cooling chamber 20 and the relay tank 6. By turning on the power, the temperature detection device 25 and the refrigeration control device 27 are activated. Each relay xI +X2 is energized through the relay, the normally open contact XII r
1 valve 29.31PL is opened, and at the same time each normally open contact X1
3 * X23 is turned on and the refrigeration device 28 is activated,
Cooling operation is started.

In this case, since the heat load is larger in the cooling chamber 2o than in the relay tank 6, even if the cooling chamber SO is being cooled, the mixed liquid in the relay tank 6 is cooled down faster, and the temperature detection device 2
j- contact is turned off, the No. 1 Corrilay x2 is demagnetized, the normally open contact 41 is turned off, and the second control valve 31a is closed, and the supply of refrigerant to the first evaporation pipe 22 of the relay tank B is stopped. be done.

At this point, the normally open contact XtS is also turned off, but since one of the normally open contacts XtS is on, the refrigeration device 28 continues to operate.

When the temperature inside the relay tank 6 rises again while the cooling chamber λ0 is being cooled by the above operation, the temperature detection device 25 is turned on, and the second control valve 31IL is turned on.
When the valve is opened, refrigerant is again supplied to the first evaporation pipe 2-, and the relay tank 6 is cooled.

Therefore, when the cooling chamber B is being cooled, the temperature detection device 2 of the relay tank B! Due to the action of r, cooling and stopping are repeated.

When the cooling chamber -0 is sufficiently cooled and the frozen carbonated beverage is completed, the contact of the refrigeration control device 27 is turned off,
The first relay X is demagnetized, the first control valve 29 is closed by the normally open contact X11, and the supply of refrigerant is stopped. At the same time, if the contact of the temperature detection device 25 is off, the first relay X2 is also demagnetized, so the normally open contact
Since I3 and XtS are also in the off state, the refrigeration device λg
stops.

Further, as time passes and the temperature in the cooling chamber λθ rises, the contact point of the refrigeration control device 27 turns on, and the first control valve 2
The cooling chamber 20 is cooled again by opening the valve 9 and starting operation of the refrigeration unit g.

Therefore, the cooling chamber 2o and the relay tank 6 are connected to the temperature detection device UT, the refrigeration control device 27, and each control valve 9. ,1l
Cooling is performed individually by the refrigeration control circuit section 3da having tL, and the interiors of the cooling chamber 2o and the relay tank B can be maintained in an optimal cooling state.

In addition, in the case of non-implementation, cooling room -〇 and relay tank B are each dedicated to 〇. Although we have described the case in which the four valves λf and 3/IL are provided, the refrigeration control device λ7 is configured to operate the refrigeration device 28 only while cooling the cooling chamber KO without using the first control valve 2D. The first control valve 31 cools the relay tank B only when the refrigeration system 28 is in operation.
It is also possible to control the refrigerant by opening and closing 1L.

g1 Effects of the Invention Since the present invention has the above-described configuration and operation, by cooling the relay tank, the mixed liquid is kept cold without freezing at below io℃, and is always stored in a hygienically favorable condition. can. Since the product is sufficiently kept cool in the relay tank, the cooling time required to complete product manufacturing in the cooling room is shortened.
1. Also, because the mixed liquid in the relay tank is at a low temperature, carbonation is carried out well, and there is very little need to change the carbon dioxide pressure due to changes in water temperature, resulting in a product with a refreshing sensation and a good rise. I can do it.
