Example Embodiment

[0023] Example 1

[0024] The first step is to remove the red skin of the peanuts, then dry them at 85°C until the moisture content is less than 5%, and then crush them;

[0025] In the second step, the obtained crushed material is sent to a low-temperature press for pressing, the pressing temperature is 45°C, and the press chamber pressure is 3.0Mpa to obtain crude oil;

[0026] The third step is to filter the crude oil with a 100-mesh screen at low temperature to remove particles;

[0027] In step 4, add bentonite and diatomaceous earth to the filtered crude oil obtained in step 3, and then send it to the ceramic membrane for filtering and degumming. The added amount of bentonite and diatomite are respectively the weight of the filtered crude oil 3%; the molecular weight cut-off of the ceramic membrane is 20000Da, the filtration temperature is 30℃, the filtration pressure is 0.3Mpa, and the average operating flux of the ceramic membrane within 4 hours of operation is 25L / m 2 ·H;

Example Embodiment

[0032] Example 2

[0033] The first step is to remove the red skin of the peanuts, then dry them at 90°C until the moisture content is less than 5%, and then crush them;

[0034] In the second step, the obtained crushed material is sent to a low-temperature press for pressing, the pressing temperature is 60°C, and the press chamber pressure is 3.5Mpa to obtain crude oil;

[0035] The third step is to filter the crude oil with a 120-mesh screen at low temperature to remove particles;

[0036] In step 4, add bentonite and diatomaceous earth to the filtered crude oil obtained in step 3, and then send it to the ceramic membrane for filtering and degumming. The added amount of bentonite and diatomite are respectively the weight of the filtered crude oil 6%; the molecular weight cut-off of the ceramic membrane is 40000Da, the filtration temperature is 30℃, the filtration pressure is 0.5Mpa, and the average operating flux of the ceramic membrane within 4 hours of operation is 22L / m 2 ·H;

[0041] Example 3

[0042] The first step is to remove the red skin of the peanuts, then dry them at 85°C until the moisture content is less than 5%, and then crush them;

[0043] In the second step, the obtained crushed material is sent to a low-temperature press for pressing, the pressing temperature is 50°C, and the press chamber pressure is 3.2Mpa to obtain crude oil;

[0044] The third step is to filter the crude oil with a 110-mesh screen at low temperature to remove particles;

[0045] In step 4, add bentonite and diatomaceous earth to the filtered crude oil obtained in step 3, and then send it to the ceramic membrane for filtering and degumming. The added amount of bentonite and diatomite are respectively the weight of the filtered crude oil 5%; The molecular weight cut-off of the ceramic membrane is 30000Da, the filtration temperature is 30℃, the filtration pressure is 0.4Mpa, and the average operating flux of the ceramic membrane within 4 hours of operation is 28L / m 2 ·H;

Abstract

The invention relates to a fine finishing method for high-quality peanut oil, and belongs to the technical field of peanut oil production. The fine finishing method comprises the steps of removing red skins of peanuts and performing smashing treatment; pressing the processed peanuts by a low-temperature presser to obtain rough oil; filtering the rough oil by a screen, and then performing filtering and de-gumming processing in a ceramic film; adding active carclazyte to obtained ceramic film filtering liquid, performing de-coloration processing, and filtering to obtain de-colored peanut oil; performing vacuum deodorization on the de-colored peanut oil; and cooling the de-odorized peanut oil, adding an adsorbent, and performing hydraulic filtering to remove solid body to obtain the fine finished peanut oil. By performing fine finishing on the low-temperature pressing process of the peanuts, de-gumming, deodorization and oil fat removal are realized, so that the quality of the peanut oil is improved and fine finishing of the peanut oil is realized.

Description

technical field [0001] The invention relates to a high-quality peanut oil finishing method, belonging to the technical field of peanut oil production. Background technique [0002] Traditional peanut oil is generally produced by high-temperature pressing. With the continuous improvement of people's living standards, higher requirements for dietary health are put forward, and low-temperature pressing peanut oil has entered people's field of vision. Ordinary peanut oil is extracted at a high temperature of 120°C. It has a deep color, high content of saturated fatty acids, and relatively large damage to nutrients. Therefore, long-term consumption of traditional vegetable oil will cause great harm to human health. The low-temperature pressing peanut oil adopts the low-temperature pressing technology at 60°C. The peanut oil produced is pure and clear, with a natural and delicate flavor, and can better retain peanut protein powder, which is conducive to the full utilization of pea...
