Description

  TECHNICAL FIELD The present invention relates to a refining apparatus for refining oil that removes minute impurities contained in the crude oil.

  Conventionally, edible or cosmetic oils such as coconut oil, corn oil, sesame oil and the like have to reduce the acid value for beauty, health, etc., and this causes an increase in acid value. It is desired to remove minute impurities. As a method for removing such minute impurities, active hydrogen is generated by decomposing water by adding water to the crude oil in the processing tank, pressurizing and heating, and the action of this active hydrogen. Is used to burn and remove minute impurities in the crude oil and to refine the crude oil to reduce its acid value.

  However, when the crude oil is pressurized and heated as described above, the crude oil is denatured and converted to trans fatty acids. For this reason, when used for edible oil, cosmetic oil, etc., it is said that it binds to active oxygen in the body and is not good for beauty and health.

  For this reason, conventionally, crude impurities are passed through a plurality of stacked filters, and fine impurities in the crude oil are filtered and removed. However, in such a method of passing through a plurality of laminated filters, very minute impurities cannot be filtered. Therefore, it is impossible to obtain pure purified oil, so-called pure virgin oil, having high acid value. .

  In view of such a situation, the present invention removes the minute impurities to reduce the acid value without degrading the crude oil of camellia oil into a trans-type fatty acid which is said to be not good for beauty and health. An object of the present invention is to provide a refining device for camellia oil that can obtain a refined oil.

The present invention has been made in order to achieve the above-described problems and objects in the prior art, and the refined apparatus of the present invention has laminated special filters (64, 66, 68). With
An activated carbon electrode (70, 72) made of fibrous activated carbon is disposed between the laminated special filters (64, 66, 68),
A special filter part (60) in which a mesh filter (74) made of stainless steel is arranged below the lowermost laminated special filter (68),
It is characterized in that when the crude oil of kerosene is passed through the special filter section (60) and impurities contained in the crude oil of kerosene are removed, the impurities are removed from the crude oil of kerosene.

  By configuring in this way, the impurities in the crude oil are adsorbed and removed by the filter by passing through a plurality of stacked filters, but a voltage is applied between the electrodes arranged between the filters. However, since impurities are removed, fine impurities are removed by the action of electrodeposition, adsorption, and electrophoresis, and a pure refined oil having a reduced acid value can be obtained. Moreover, since the oil refined in this way is not pressurized or heated, it is a toliglyceride oleate that has not been modified into trans fatty acids, so even when used for edible oils, cosmetic oils, etc. Since it does not bind to active oxygen in the body, it is extremely good for beauty and health.

  In addition, by passing through the activated carbon electrode the oil with reduced acid value from which impurities have been removed by passing through the filter, impurities can be further adsorbed and removed. Refined oil can be obtained.

Moreover, the refiner | purifier of the coconut oil of this invention is characterized by the voltage applied between the said electrodes being 5-20KV.
By setting the applied voltage in such a range, the minute impurities contained in the crude oil are efficiently collected by the action of electrophoresis, and are adsorbed and removed by the filter and activated carbon electrode, resulting in pure purification with reduced acid value. Oil can be obtained.

Moreover, the refiner | purifier of the coconut oil of this invention is characterized by the said lamination | stacking special filter (64, 66, 68) laminating | stacking Japanese paper and a filter paper.
By configuring in this way, the minute impurities contained in the crude oil of cocoon oil are efficiently collected by the action of electrophoresis, and are adsorbed and removed by the filter and activated carbon electrode to obtain a pure refined oil with reduced acid value. be able to. In addition, it is said that camellia oil is particularly effective for beauty and health, and refined camellia oil is not pressurized and heated, so it is not modified to trans fatty acids and is oleic acid triglyceride. Even when used in edible oils, cosmetic oils, etc., it does not bind to active oxygen in the body, so it is very good for beauty and health.

  According to the present invention, fine impurities contained in crude oil are accumulated on the activated carbon electrode side which is one electrode by the action of electrophoresis, and the oil from which impurities accumulated in the vicinity of the other electrode side are removed is activated carbon. By passing the electrode, impurities in the crude oil can be further adsorbed and filtered to obtain a pure refined oil having a reduced acid value.

  Moreover, since the oil refined in this way is not pressurized or heated, it is a toliglyceride oleate that has not been modified into trans fatty acids, so even when used for edible oils, cosmetic oils, etc. Since it does not bind to active oxygen in the body, it is extremely good for beauty and health. Further, in the present invention, since the crude oil is cocoon oil, minute impurities contained in the crude oil of cocoon oil are efficiently accumulated on the activated carbon electrode side which is one electrode by the action of electrophoresis, and in the vicinity of the other electrode side. By passing through the activated carbon electrode the oil from which the impurities accumulated are removed, the impurities in the crude oil can be further adsorbed and filtered to obtain a pure refined oil having a reduced acid value.

  In addition, it is said that salmon oil is particularly effective for beauty and health, and the refined salmon oil is not pressurized or heated, so it is not modified to trans fatty acid and is oleic acid triglyceride. Even when used in edible oils, cosmetic oils, etc., it does not bind to active oxygen in the body, so it is extremely excellent in beauty and health, and has many outstanding and unique effects.
