TH24339B - Purification of edible oils containing high amounts of natural carotene and vitamin E. - Google Patents

Abstract

This invention reveals a process for producing purified oils. And eliminates odors which are high in natural carotene by applying pressure to oil less than 0.060 mbar and temperature less than 200 ํ and where the process includes the process of oil refining in the distillation machine with Short path at temperature range 160 ํ to 290 ํ and at pressure of 0.003 m bar to 0.08 m bar, and free fatty acid removal (FFA) in oil by condensation inside the FFA distiller is eliminated by means of a mixture. The oil and FFA pass into an internal condenser system, which - operating at a temperature higher than the FFA's melting point in the oil. Deodorization, especially palm oil, while the carotene and vitamin E contained in the fed oil are well preserved in the processed oil.

Claims (1)

1.Processing of purified and deodorized oils with carotene Natural content by passing crude oil or pre-treated oil Pressure less than 0.060 mbar and a temperature less than 200 ํ C, which gives the appearance It is special that the process includes the following steps: a) pre-distillation of crude or pretreated oil at a commercial rate of approximately 1000 kg / h in a short-path distillation apparatus at a temperature range of 160 ° C to 200 ° C. C and at a pressure of 0.003 mbar to 0.08 mbar and b) removal of free fatty acids (FFA) in oil by condensation inside the distillation unit, whereby the FFA removal process consists of the condensation of the oil-FFA mixture through a condenser. Inside operating at temperatures in between FFA melting point and temperatures below the FFA condensation point to immediately condense the FFA vapor when oil and FFA are introduced into the smear. To produce oil It contains a high content of natural carotene, with the lowest carotene and vitamin E content of 90% in the pre-treated oil before being treated. It is fed to the distillation apparatus and contains less than 0.1% FFA. 2. The purified and deodorized oil production process with carotene. Natural content by passing crude oil or pre-treated oil Pressure less than 0.060 mbar and temperature less than 200 ํ C, which gives the effect that the process includes the following steps: a) the distillation of crude or pretreated oil before the rate at the commercial level is estimated. 2000 kg / cm in a short-path distillation apparatus at a temperature range of 160 ° C to 200 ° C and at pressure of 0.003 mbar to 0.08 mbar and b) Free fatty acid removal (FFA) in oil by condensation inside the distiller. The FFA elimination procedure consists of the introduction of a mixture. Between oil and FFA goes through an internal condenser operating at a It is between the FFA melting point and the temperature below the FFA condensation point to condense the FFA vapor immediately when the oil and FFA are introduced into the smoker. To produce purified and deodorized oils with a high content of natural carotene. Which contains 90% of the lowest carotene and vitamin E in the pre-treated oil Before being fed to the distillation machine and less than 0.1% FFA. 3. The process of purifying and deodorizing oils with natural carotene. It is characterized by high volumes of crude or pre-treated oil through pressures of less than 0.060 mbar and temperatures of less than 200 ํ C, which gives it a special effect. That process includes the following steps: a) pre-distillation of crude oil or pre-treated oil at commercial scale rates of 1000 kg / h to 2000 kg / h in short-path distillation machines at temperature ranges. 160 ° C to 200 ° C and at pressure of 0.003 mbar to 0.08 mbar and at pressure 0.003 mbar to 0.08 mbar and b) Free fatty acid removal (FFA) in oil by condensation inside the distiller. This FFA consists of the transfer of an oil-FFA mixture through an internal condenser operating at temperatures between the FFA melting point and below the FFA condensation point to condense the FFA vapor immediately when oil and FFA are introduced. Into the suppressor To produce oil It contains a high content of natural carotene, 90% of the lowest carotene and vitamin E content in pre-treated oil before being fed. It enters the distillation apparatus and it has less than 0.1% FFA. 4. Process as stated in claim 1 or 2 or 3 where the oil is The gas is prepared to be heated to 160 ํ C and the gas is removed 5. Process as outlined in claim 4, where the oil is gassed in A gas removal unit with a condenser with return distillation 6. Process as described in claim 1 or 2 or 3 where the condenser Inside will work with the flow through the casting. And where the temperature of the coolant is high Slightly higher than the melting point of the FFA. 7. Process as stated in Claim 1 or 2 or 3, where oil is Rubber removed and bleached oil 8. Process as stated in claim 1 or 2 or 3 where the oil is Crude or pre-treated palm oil 9. The process outlined in claim 8, which selects oil from oil. Rubber removal and bleaching, Palm oil that has been removed and bleached, Palm olein With rubber removal and bleaching, palm stearin from rubber removal and bleaching, crude olein from palm, crude palm stearin, mid-distilled part from rubber removal palm And bleached, crude super olein from palm that removes rubber and bleach, distilled part In the middle, from crude palm, super olein from palm, crude palm oil or hybrid palm oil 1 0. The purification process according to claim 1 or 2 or 3 where the process is also performed under vacuum. Vacuum system, where the vacuum system is protected by multiple coolant filters with cooling coils. Different Temperature can be varied independently from -15 ํ C to +5 ํ C during operation and up to 60 ํ C during defrost 1. 1. Process as stated in claim 1 or 2 or 3, where temperature The internal condenser operating is approximately 57 ํ C.
