After containing the vegetable oil 2 and sealing the container 1 with the lid 3,
Oxygen is supplied from the raw material oxygen supply unit 4 into the ozone generator 5 to generate ozone by silent discharge, and the generated ozone is sent to the ozone diffuser 7 through the ozone supply pipe 6, and the ozone diffuser 7 forms bubbles. The ozone ejected from the container 1 is brought into contact with the vegetable oil 2 to produce ozonized vegetable oil.
From the wastewater to an ozone decomposer 9 where it is decomposed by a catalyst and released into the atmosphere.

However, in the conventional method as described above, the viscosity of the vegetable oil 2 gradually increases depending on the degree of ozonation, but the vegetable oil 2 precipitates insolubles at room temperature, making it difficult to inject ozone. There is a problem that the pressure of ozone rises, the ozone concentration becomes unstable, and ozonated vegetable oil cannot be produced stably.Moreover, depending on the type of vegetable oil, ozonation may be difficult. In this case, it is necessary to use an expensive ozone decomposition catalyst to decompose excess unreacted ozone, so that there is a problem that the production cost is increased.

Reference numeral 11 denotes an air diffuser provided at a lower portion in the ozone absorbing container 10, reference numeral 12 denotes an exhaust ozone supply pipe for supplying surplus ozone used for ozonization in the container 1 to the ozone absorbing container 10, and reference numeral 13 denotes the ozone A drain ozone exhaust pipe used in the absorption vessel 10 for discharging excess surplus ozone, the leading end of the ozone supply pipe 12 is connected to the diffuser pipe 11, and the excess ozone is ejected into the ozone absorption vessel 10. By contacting and absorbing the vegetable oil 2 to ozonize the vegetable oil 2, surplus ozone is released from the exhaust ozone discharge pipe 13 into the atmosphere. That is, in the conventional method, surplus ozone used for ozonization of vegetable oil in a container is sent to a waste ozone decomposer and decomposed by a catalyst to release ozone into the atmosphere. In the method of the present invention, surplus ozone in the container 1 is used again for ozonation of vegetable oil, so that ozone consumption can be reduced, and vegetable oil can be efficiently ozonated and expensive. Since no special catalyst is used, the cost of ozonizing vegetable oil can be reduced.
