Problems solved by technology

However, in the pomegranate oil produced by the extraction method, there are many residues of organic solvents that cannot be completely removed, which destroys the natural, environmentally friendly and safe characteristics of pomegranate seed oil. It is not accepted by high-end products and can only be used for low-end products; Pressing method, the antioxidant components in pomegranate oil are destroyed, losing a lot of health benefits
However, although the low-temperature cold pressing method does not have the above-mentioned defects, it is actually useless because of the low oil yield.
Is there a better way to make pomegranate seed oil? Extensive searches have been carried out for the above problems, but no ideal technical solutions have been found

Embodiment 1

[0008] Embodiment 1: Get dry coarse pomegranate seeds 1200g, through winnowing, cleaning, dehydration, drying pretreatment steps, remove pomegranate skin debris, shriveled seeds, magazines, ash etc., get refined pomegranate seeds 1100g, moisture content 9 %. 1100 g of the above-mentioned refined pomegranate seeds were all put into a high-frequency electromagnetic oscillator (general industrial equipment) for high-frequency oscillation treatment, the oscillation frequency was 1800 times / min, and the time was 9 minutes. The pomegranate seeds after the vibration treatment were continuously added (10 kg / hour) into a screw press (universal oil extraction equipment) to be squeezed under a pressure of 2 kg and a temperature of 65° C. Finally, the net weight of the crude oil was 60g, and the oil yield was 5.45%. Put the pomegranate seed residue after pressing into a centrifuge for centrifugal deoiling to obtain a crude oil with a net weight of 20 g and an oil yield of 1.82%. The abo...

Embodiment 2

[0009] Example 2: 3000 g of dried coarse pomegranate seeds were taken, and 2700 g of refined pomegranate seeds were obtained with a water content of 8.5% through the pretreatment steps of winnowing, cleaning, dehydration and drying. Put 2700 g of the above-mentioned refined pomegranate seeds into a high-frequency electromagnetic oscillator for high-frequency oscillation treatment, the oscillation frequency is 1500 times / min, and the time is 8 minutes. The pomegranate seeds after the vibration treatment were continuously added (10 kg / hour) into a cold-pressing screw press and squeezed with a pressure of 2.2 kg and a temperature of 70° C. Finally, the net weight of the crude oil was 162g, and the oil yield was 6%. Put the pomegranate seed residue after pressing into a centrifuge for centrifugal deoiling to obtain a crude oil with a net weight of 51 g and an oil yield of 1.9%. The above two crude oils obtained were combined to obtain 213g of crude oil, which was left to stand fo...

Abstract

The cold squeezing process of producing pomegranate seed oil includes the following steps: pre-treating pomegranate seed through wind selecting, washing, air drying and stoving to result in water content of 6-10 %; vibration treating pomegranate seed in a HF electromagnetic vibrator at frequency of 500-3000/min for 5-10 min; squeezing pomegranate seed in an oil press at 50-80 deg.c to obtain the first crude oil; centrifugally oil extraction with the squeezed residue to obtain the second crude oil; merging the crude oil, stilling for 2-5 days and final filtering to obtain finished pomegranate seed oil product. The process has oil extracting rate up to 7-11 %, and is simple, clean, environment friendly and high in oil extracting rate. The produced pomegranate seed oil has the nutritious components of pomegranate seed well maintained.

Description

Technical field: [0001] The invention relates to a method for preparing vegetable oil, in particular to a method for pressing pomegranate seeds to obtain pomegranate seed oil. Background technique: [0002] Because pomegranate seeds contain polyunsaturated oil, which contains punicic acid, linolenic acid, oleic acid, palmitic acid, stearic acid, etc., of which the content of punicic acid is more than 80%, it has a strong antioxidant capacity and can be used for It resists human inflammation and the destructive effects of oxygen free radicals, and helps to improve joint elasticity and skin elasticity, strengthen arteries, veins and capillaries, and also has a positive adjuvant therapeutic effect on eye diseases, such as retinal inflammation caused by diabetes. Because the oil content of pomegranate seeds is low (14-18%), it is difficult to peel the kernels, and the process of extracting pomegranate seed oil is relatively difficult. Therefore, the development and utilization o...
