Problems solved by technology

However, when these basic compounds are directly contacted with oil, not only the specific surface area is low, the intrinsic adsorption and reaction energy are small, but also the metal soaps generated by the reaction with free fatty acids are dissolved and transferred to the oil after treatment. May impair the flavor of the oil
[0005] In the device for regenerating used edible fats and oils, in the type of device that transfers the oil from the fryer to a dedicated receiving container, it is necessary to stop the operation of the fryer when performing the regeneration of used edible oils and fats , especially inconvenient when trying to keep the fryer running continuously
In addition, the regeneration treatment operation and the cleaning operation after the operation become new burdens

Embodiment 1

[0098] 1900ml of an aqueous suspension containing 70g of magnesium carbonate (produced by Kamijima Chemical Industry Co., Ltd.) was stirred at room temperature while titrating 76% formic acid until the aqueous suspension became transparent to obtain an aqueous solution containing magnesium ions. Then, 1000g of silicon dioxide (produced by Mizusawa Chemical Industry Co., Ltd., trade name MIZUKASORB C-6) was immersed in the above-mentioned aqueous solution containing magnesium ions, dried at 120°C overnight, and then fired at 450°C for 6 hours, a silica cake carrying about 3 wt% of MgO was thus obtained, and the above cake was pulverized and passed through a sieve, and the material with a particle size of 150-300 μm was used as the treatment agent A-1.

Embodiment 2

[0100] According to the same method as in Example 1, a silica cake carrying about 15 wt% of MgO was obtained. The cake was pulverized and sieved to obtain a material with a particle size of 150-300 μm as the treatment agent A-2.

Embodiment 3

[0102] (Preparation of Treatment Agent B-1)

[0103] According to the same method as in Example 1, a silica cake carrying about 27.5 wt% of MgO was obtained. The cake was pulverized and sieved to obtain a material with a particle size of 150-300 μm as the treatment agent A-3.

Abstract

The reproduction filter of the used edible oil is obtained by processing the mixture of a treating agent A (powder obtained by supporting a basic compound of such as magnesium oxide, calcium oxide, magnesium hydroxide, potassium hydroxide to silicon oxide) which can adsorb free fatty acid selectively or can convert it to a compound which is hardly melted in oil and a treatment agent B (powder of the silicon oxide, active carbon and activated clay) which can adsorb colored matter selectively to be a replenishing filter or a paper-blended rolled filter. The regeneration apparatus consists of a sucking tube for taking out the used oil in a fryer oil tub; a reproduction apparatus consisting of the reproduction processing filter and a container for housing the reproduction processing filter; aliquid-feeding pump or a suction pump; and a return tube for returning reproduced oil to the fryer oil tub.

Description

technical field [0001] The present invention relates to a filter for refining used edible oils and fats whose quality values, such as acid value, chroma, and peroxide value, exceed the quality standards of edible oils and fats, and a regeneration treatment device using the filter. Processed and reprocessed until edible quality levels are achieved. Background technique [0002] Used edible fats and oils produced in households, the dining out industry, and food manufacturing, etc., contain free fatty acids generated by hydrolysis of fats and oils, peroxides generated by thermal deterioration reactions, odorous substances, polymers, coloring substances, etc. Trace metals leached from the inner wall of the fryer and various non-greasy substances transformed from the materials used for meals. These deterioration products tend to accumulate with use, and become harmful substances harmful to health if they are used for a certain period of time. Various non-greasy substances conve...
