Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for filling beverage fluids such as milk from a surge tank into sales containers via a filling machine.

To fill beverage containers with a beverage fluid, such as milk, the milk is temporarily stored in a surge tank, which supplies the milk through a filler tank to a filling machine, which then pours the milk into the containers. However, conventionally, the method of supplying this milk to the filler tank has been a head system or a pump pressure system. Here, the head method is a method in which the surge tank is placed at a high place and the milk is sent to the filler tank by the drop, and the pump pressure feed method is a method in which a pressure pump is interposed between the surge tank and the filler tank. The pump pressure is used to send the liquid to the filler tank.

By the way, in the above-mentioned head method, the surge tank must be installed at a high place, which makes the building equipment very expensive. Furthermore, when the milk flows down and the amount in the surge tank decreases, the inside of the tank becomes under negative pressure, making it difficult for the milk to flow out, so it becomes necessary to provide an air hole in the surge tank. Therefore, the air enters through the air holes, resulting in air pollution of the milk and accelerated deterioration and spoilage.

On the other hand, in the case of the pump pressure feeding method, it is difficult to clean and sterilize the pump, so there is an extremely high possibility that secondary contamination will occur due to the pump.Furthermore, as with the above-mentioned head method, there is a risk of secondary contamination caused by the surge tank breathing. There was a problem of air pollution.

As described above, the present invention provides a method for filling containers with a beverage fluid, such as milk, without installing a surge tank at a high location and without using a pressure pump. be.

An embodiment of the present invention will be described below with reference to the drawings.

1 is an air compressor and the general atmosphere is 5 k&
/ cm. 2, since the air compressed by the compressor 1 rises to about 70°C, an aftercooler is used to cool the compressed air to cool the air temperature to 37°C or less. 3 is a dryer that removes the humidity of the compressed air cooled by the nuclear cooler 2. 4 is dust removal filter 4
a.

The filter device consists of an oil removal filter 4b and a deodorizing filter 4c, and the dust removal filter 4a removes only relatively large dust. 5 is a pressure reducing device that reduces the pressure of the compressed air that has passed through the filter device 4 to compressed air of about 2 to 0°2 kll/am, regulates the pressure within the withstand pressure limit of the surge tank to be described later, and protects the surge tank. This is provided to protect a high-performance filter, which will be described later, from high-pressure air flow. 6 is a dust removal and sterilization filter that combines a medium-performance filter that removes very small dust contained in reduced pressure compressed air and a high-performance filter that also removes bacteria, and the air that passes through it is filtered. is hot, humid, oil-free, odorless, dust-free, and sterile. 7 is a surge tank, and the 2 to 0- that has passed through the dust removal and sterilization filter 6 is
Compressed air of 2 klil/cm is supplied from the air supply lower a, and is always in a pressurized state. Note that 7b is a supply port for drinking fluid such as milk, 8 is a filler tank for storing drinking fluid from the surge tank 7, and 9 is a sales container 1.
This is a filling machine that injects beverage fluid into a container and seals it.

Figure 2 shows how each of the devices 1 to 6 described above is made into a unit.
By being integrated in this way, it can be easily connected to the existing surge tank 7, and installation and management are also very easy.

Accordingly, in the method according to the present invention, the compressor 1
The compressed air is made hot and humid by a dryer, large dust is removed by a filter device 4, and it is made oil-free and odor-free, and the pressure is further reduced by a pressure reducing device to 2 to 0.2 kllaa.
of compressed air, and then filtered with dust removal and sterilization filter 6 to 0.3
Since dust and bacteria larger than μ have been removed to make it dust-free and sterile, if this compressed air is sent to the surge tank 7, the inside of the surge tank 7 will always be in a pressurized state, and the beverage fluid inside will be kept in a pressurized state. can be flowed out under pressure and supplied to the filler tank 8,
Via the filling machine 9, the sales containers 10 can thus be filled with beverage fluid.

Moreover, since the drinking fluid will not be contaminated even if it comes into contact with compressed air, it is possible to suppress the deterioration and spoilage of the drinking fluid without using conventional chemical methods that use preservatives or sterilizers. It is possible to maintain the flavor of natural foods.

As described above, the present invention sends compressed air into the surge tank and uses the pressure to cause drinking fluids such as milk to flow out. Therefore, the number of building equipment can be reduced, and the compressed air is heated and humid. Since the air is oil-free, odorless, dust-free, and sterile, it can be protected from deterioration and spoilage without using traditional chemical methods, and it also protects the natural flavor.
In addition to this, if it is made into a unit, it has the advantage that it can be easily connected to an existing surge tank for use.

Claims (1)

[Claims] The air compressed by the compressor is cooled and dehumidified, then passed through a filter device to remove dust, oil, and odor, and then passed through a high-performance filter to become sterile and dust-free compressed air. This compressed air is sent into the surge tank. 1. A method for filling a container with a beverage fluid, characterized in that the beverage fluid in the surge tank is filled into the container via a filling machine.
