Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for cleaning and sterilizing food manufacturing machines, filling and packaging containers, etc., and an apparatus for producing cleaning and sterilizing water used in the method.

Bottling Machine 2 Conventionally, clean water or water containing a small amount of disinfectant such as chlorine has been used to clean and sterilize canning machines, liquid processing machines, various other food manufacturing machines, food filling and packaging containers, etc. However, when only clean water is used, it is possible to wash away stubborn dirt and bacteria with a certain probability, but it cannot be sterilized, and when chlorine etc. is added, the sterilization properties increase, but If chlorine-containing water corrodes the processing equipment or gets mixed into the product liquid, there is a risk that the flavor, color, aroma, etc. of the product will be impaired. It had such problems.

The present invention has been proposed in view of the above-mentioned points, and its purpose is to provide a food manufacturing machine and filling machine that has a cleaning and sterilizing effect, is harmless, and has no risk of impairing product quality or corroding the machine. An object of the present invention is to provide a method for cleaning and sterilizing packaging containers, etc., and an apparatus for producing cleaning and sterilizing water used in the method.

The present invention is a machine for producing water-filled foods by mixing clean air containing ozone or oxygen with clean water.

The gist is a food manufacturing machine that cleans and sterilizes filling packaging containers, etc., and a method for cleaning and sterilizing filling packaging containers, etc., which can significantly improve the cleaning and sterilizing effect compared to clean water. At the same time, since the ozone can be sterilized by harmless ozone, there is no risk of damaging the quality of the product or corroding the machinery.

The present invention relates to a clean water pumping means that pumps a predetermined amount of clean water, and an ozone generator that generates ozone using the supplied clean air or oxygen.

Cleaning sterilizing water characterized by comprising a lid and a lid, which suck clean air containing ozone or oxygen sent out from the ozone generator, mix it with the clean water pumped out from the clean water pumping means, and send it out. This production apparatus is capable of efficiently producing cleaning and sterilizing water containing ozone that has a high cleaning and sterilizing effect.

The present invention will be explained below based on two examples.

Figure 1 is a configuration diagram of a washing sterilization water production device.

1 is a water inlet, 2 is an on-off valve 23 is a water supply pipe, and 4 is a water tank.The on-off valve 2 controls the water supply according to the level of clean water supplied from the water inlet 1 and the water tank 4. The amount of water in the tank 4 is maintained at a predetermined amount.

5 is a water outlet pipe, 6 is a pressure pump, 7 is a flow rate control valve, 8
is a pressure gauge, which sucks clean water from the water tank 4 and water outlet piping 5 into the pressure pump 6, monitors it with the two pressure gauges 8, adjusts the flow rate control valve 7, and sends clean water at a predetermined flow rate to the ejector 9. It is designed to be pumped to 10 is a pressurized air or oxygen supply port, 11 is a filter, and 12 is a pressure reducing valve.

13 is a pressure gauge, 14 is an on-off valve, 15 is an ozone generator,
The pressurized air or oxygen supplied from the supply port 10 is made into sufficient clean air by the filter 10, and the pressure reducing valve 12 is used to maintain a predetermined pressure. It opens and closes in response to an operation signal, and is open only when the pressure pump 6 is in operation. The ozone generator 15 is.

Ozone is generated using supplied clean air or oxygen. 16 is a gas flow meter.

] 7 is a pressure gauge, 18 is a flow rate control valve, and 19 is a check valve. Clean air or oxygen containing ozone generated by the ozone generator 15 is supplied to the gas 1ti116 by adjusting the flow rate control valve 18.
The ejector 9 is configured to suction a predetermined flow rate while monitoring the flow rate.

The pressure gauge 17 is used to correct the flow rate of the gas flow meter 1d, and the check valve 19 prevents backflow of clean water. Note that the gas flow rate ratio 16 can also detect a difference in flow rate. Also.

The ejector 9 sucks a measured amount of clean air or oxygen containing ozone into the clean water pumped by the pressure pump 6,
This is a device that creates sufficiently fine air bubbles and measures their incorporation, and exit 2
0 to the next process, which is a bottle washing machine (not shown), a rinser for empty cans, empty bottles, plastic containers, 2 paper containers, or composite containers, and an external cleaning device for food manufacturing machines such as bottling machines. ing.

As mentioned above, a predetermined amount of clean air or oxygen containing sufficient ozone is sucked into the clean water using the ejector 9, and the bubbles are mixed in as stable fine bubbles that are difficult to coalesce. By supplying water to the rinser of various containers, the final rinse device of bottle washing machines, and the external cleaning device of food manufacturing machines such as bottling machines, it is possible to wash and sterilize various containers or externally wash and sterilize food manufacturing machines. Harmless ozone can also sterilize and deodorize the atmosphere in the workplace.

Mix ozone into clean water as described above.

Fill and package food. By using the water for rinsing containers such as one can of a bottle, one plastic container, one paper container, or a Vi composite container, it is possible to sterilize and deodorize the containers at the same time as rinsing, and to prevent corrosion of the equipment used for rinsing. can be prevented and the atmosphere can be kept in a state with few bacteria.

However, by using the above-mentioned cleaning and sterilizing water mixed with ozone as the external cleaning and sterilizing water for food manufacturing machines such as bottling machines, canning machines, capping machines, and 7-mers (cans and caps), It is possible to clean the product liquid during manufacture to prevent stains from adhering to it, and to sterilize it to a nearly sterile state without corroding the outside.

Further, the above-mentioned cleaning sterilizing water can be efficiently produced by mixing ozone-containing clean air or oxygen into the pressure-fed clean water using an ejector as fine bubbles that have a high cleaning and sterilizing effect.
