Abstract
The present invention relates to a kind of rice bran oil degreasing cooling means, include the following steps：One, oil temperature controls the speed cooling of 1 DEG C of the reduction at every 4 hours when between 20 DEG C to 8 DEG C；Two, oil temperature controls the speed cooling of 1 DEG C of the reduction at every 6 hours when between 8 DEG C to 3 DEG C；Three, it keeps oil temperature at 3 DEG C and continuously stirs crystallization growing the grain 12 hours；Four, by the rice bran oil degreasing of advantages of good crystallization, temperature is controlled at 5 DEG C~8 DEG C；Five, filter pressure 0.1MPA is controlled, filtering is recrystallized after first oil strain, obtains first-grade rice bran oil.The present invention can solve the disadvantage of rice bran oil degreasing difficulty, be conducive to the crystallization of fat, and grease interest rate is high, and oil-containing is few in rice bran fat, effectively grease is avoided to be wrapped in rice bran oil, facilitates filtering, is conducive to detect by refrigeration test.
Description
Technical field
The present invention relates to rice bran oil degreasing cooling technology field, specifically a kind of rice bran oil degreasing cooling means.
Background technology
Rice bran oil is rice bran deep-processing products, rich in abundant linoleic acid, oleic acid, vitamin E, oryzanol, sterol, simultaneously
Also contain a small amount of saturated acid fat in rice bran oil so that can become muddy in storing process and there is floating material, seriously affect
Appearance, quality and the mouthfeel of product, it is therefore desirable to rice bran oil ungrease treatment.But the degreasing of rice bran oil is a difficult point, fat
Bad, the case where just will appear grease package is crystallized, and is inconvenient to filter, it is difficult to detect by refrigeration test.
Invention content
In order to avoid with solve above-mentioned technical problem, the present invention proposes a kind of rice bran oil degreasing cooling means.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of rice bran oil degreasing cooling means, includes the following steps：
Step 1：Oil temperature controls the speed cooling of 1 DEG C of the reduction at every 4 hours when between 20 DEG C to 8 DEG C.
Step 2：Oil temperature controls the speed cooling of 1 DEG C of the reduction at every 6 hours when between 8 DEG C to 3 DEG C.
Step 3：It keeps oil temperature at 3 DEG C and continuously stirs crystallization growing the grain 12 hours.
Step 4：By the rice bran oil degreasing of advantages of good crystallization, temperature is controlled at 5 DEG C~8 DEG C.
Step 5：Filter pressure 0.1MPA is controlled, filtering is recrystallized after first oil strain, obtains first-grade rice bran oil.
Preferably, the control of oil temperature cooling velocity is realized by handpiece Water Chilling Units in the step 1 and step 2.
Preferably, the degreasing in the step 4 carries out in pressure balancing tank.
Preferably, the filtering in the step 5 carries out in plate and frame filter press.
The beneficial effects of the invention are as follows：
The present invention can solve the disadvantage of rice bran oil degreasing difficulty, be conducive to the crystallization of fat, and grease interest rate is high, in rice bran fat
Oil-containing is few, effectively grease is avoided to be wrapped in rice bran oil, facilitates filtering, is conducive to detect by refrigeration test.
Specific implementation mode
In order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, below it is right
The present invention is expanded on further.
A kind of rice bran oil degreasing cooling means, includes the following steps：
Step 1：When oil temperature naturally cools to 20 DEG C or less, is adjusted within every 4 hours once by handpiece Water Chilling Units, every time will
Oil temperature closes cold water after reducing by 1 DEG C, allows its natural cooling crystallization, until oil temperature is down to 8 DEG C.
Step 2：After oil temperature is at 8 DEG C, is adjusted within every 6 hours once by handpiece Water Chilling Units, oil temperature is reduced by 1 DEG C every time, directly
Oil temperature is extremely cooled to 3 DEG C.
Step 3：Oil temperature is continually maintained in 3 DEG C, then continuously stirs crystallization growing the grain 12 hours.
Step 4：The rice bran oil degreasing obtained after growing the grain is sent to pressure balancing tank, during which temperature control 5 DEG C~8 DEG C into
Row degreasing.
Step 5：Rice bran oil after degreasing is placed into plate and frame filter press and is filtered, while controlling filter pressure and existing
0.1MPA goes out grease separating and filtering, is recrystallized again after first oil strain and first-grade rice bran oil is obtained by filtration.
Following watch test data：
| Degreasing method | Rice bran fat oil content % | Degreasing oil yield % | 0 DEG C/5h of refrigeration test |
| Room temperature cools down | 25 | 95 | It is unqualified |
| Freezing liquid does not control 0 DEG C cooling | 45 | 87 | It is qualified |
| 0 DEG C of crystallisation by cooling of cooling water control | 40 | 91 | It is qualified |
| 3 DEG C of crystallisation by cooling of cooling water control | 30 | 95 | It is qualified |
| - 3 DEG C of crystallisation by cooling of cooling water control | 55 | 88 | It is qualified |
In conclusion the present invention can solve the disadvantage of rice bran oil degreasing difficulty, be conducive to the crystallization of fat, grease interest rate
Height, oil-containing is few in rice bran fat, effectively grease is avoided to be wrapped in rice bran oil, facilitates filtering, is conducive to detect by refrigeration test.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention
Principle, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these variation and
Improvement is both fallen in claimed invention.The claimed scope of the invention is by appended claims and its equivalent circle
It is fixed.
