TH3202A - How to remove wax from edible vegetable oil - Google Patents

Abstract

The process for combining the bleaching and de-waxing methods of vegetable oils consists of a sufficient amount of the vegetable oil bleaching process with bleaching soil and easy filtering agents. It is done at a temperature of 80-130 c. For about 15-60 minutes, followed by bleaching vegetable oil. The bleached clay is rapidly cooled to a temperature of about 0-15 c. For about 15 minutes to 4 hours to remove the wax from the vegetable oil. The used bleaching soil, wax materials and other impurities contained in the vegetable oil were separated at a low temperature of 0-20 C by filter method. To recover the bleached and waxed vegetable oils

Claims (3)

1. A method for bleaching and removing plant wax, which is performed in the same process that includes (a) removing the viscose from vegetable oil by cooling down to a temperature of 0-20 then mixing the oil. With sufficient amount of cold water while a person is present to hydrate the sticky rubber contained in the vegetable oil. This will make the hydrated sticky rubber insoluble (b) separate such oil from the hydrated sticky rubber contained in the oil by centrifuge and make it free of water. Therefore, the water level contained in the oil is reduced to approximately 0.1% less (c). The oil is bleached with sufficient bleaching clay and a phosphate-free easy-filtering agent. Foric acid at a concentration of approximately 75-85% is also present in 0.04 to approx. 0.12% by weight of the said oils under vacuum and reheated at 100-110 ํ for approximately 30 min. (D) Cooled the bleached oil containing the bleached clay. Rapidly while manpower at a lower temperature On average, 10-20 r / min to 0-15 ํ and maintain this temperature for 15 minutes to 4 hours to remove the wax from the oil (e). use The wax-like material and other impurities are removed from the oil by re-filtration at a temperature of approximately 0-20 ° C and (f) recovered the bleached and waxed vegetable oil. For bleaching and removing wax from vegetable oils in a single process consisting of (a) removing viscose from vegetable oil by cooling down to 10-20 repeatedly and mixing the oil with 3% cold water. While manpower to hydrate the sticky rubber contained in the vegetable oil (B) separates the oil from the hydrated sticky rubber which is contained in the oil by centrifuging and keeps it free of water. Thus, the water level in the oil is reduced by approximately 0.1% (c). The oil is bleached with sufficient amount of bleach clay and a simple filter aid with phosphoric acid. Which has a concentration of 85% with approximately 0.08 to 0.10% by weight of the said oil. Repeatedly for 20-30 minutes (d) the bleached oil, which contains the bleached clay, cools quickly while the bleached person is in a vacuum 100-105 for 20-30 minutes. At an average temperature reduction rate of 10-2 ํ per minute to 7-10 ํ and maintain this temperature for 1-2 hours, thus removing the wax from the said oil (e). Used bleaching Wax-like materials and other impurities It is removed from the oil by filtration at a temperature of 10-15 ํ and (f) recovers the bleached and waxed vegetable oil. 3. Method for bleaching and removing corn oil wax. Easy to do in the same step. This consists of (a) removing the viscose from corn oil by cooling it down to approximately 10 ํ and mixing the oil with approximately 3% cold water while stirring for approximately 30 minutes to stabilize the existing rubber. In the corn oil it is hydrated to (B) To separate the oil from the hydrated sticky rubber contained in it by centrifuging and dehydrating the oil. To reduce the water level in the oil to less than approximately 0.1% (c) bleach the oil with sufficient bleaching clay and an easy-to-filter compound with phosphoric. Acid concentration of about 85% with about 0.08-0.10% by weight of the oil. Under vacuum and repeated stirring at a temperature of 100-105 for approximately 20 minutes (d) quickly cools the bleached oil, which contains the bleached clay. While the person at the rate of lowering the temperature On average, about 15 ํ per minute, reach a temperature of about 10 ํ and maintain this temperature for about 1 hour to remove the wax from The oil (e) separates the bleached clay that has been used. Wax-like materials and other impurities (F) the bleached and waxed corn oil is recovered. 4. Method according to claim 1 of the said vegetable oil. It was selected from a group containing corn oil, milo oil, rapeseed oil (canola), rice bran oil, sunflower oil. And safflower. 5. Method according to claim 1. The vegetable oil was purified in the alkali before the bleaching process. 6. Method according to claim No. 5. The vegetable oil was made free of water. Until the water level is less than approximately 0.1% by weight after being purified in the alkali. 7. Method according to claim No. 1, the soil used for bleaching will change from approximately 0.5-5% by weight of that vegetable oil 8. Method according to claim 1, which the amount of easy filtering agent is changed from approximately 5-50 parts by weight per 100 parts bleached soil by weight 9. Method according to Clause 8. The ratio of the leaching agent to the bleached soil is approximately 1: 3, respectively 1 0. Method according to claim 1, such bleaching step was performed in a vacuum and Stir for 15-60 minutes 1 1. Method according to claim 1, which cools the bleached oil with a temperature reduction rate. 15 cycles per minute on average 1 2. Method according to claim 1: use the bleached soil as a crystalline agent to crystallize the wax 1 3. Method according to claim 1, such easy filtering agent is used to remove the bleach used soil and the wax-like material at the same time.
