Abstract

The invention discloses a production method of sunflower seed oil and the edible sunflower seed oil. The production method of the sunflower seed oil comprises the following steps: shelling collected sunflower seeds by a shelling machine to obtain sunflower kernels; airing the sunflower kernels to obtain dried sunflower kernels; adding the dried sunflower kernels to a hydraulic press, regulating pressure of the hydraulic press to 80-100 MPa at the first stage, regulating pressure of the hydraulic press to 140-160 MPa at the second stage, regulating pressure of the hydraulic press to 280-300 MPaat the third stage, and pr essing the dried sunflower kernels under three kinds of pressure to obtain crude oil; feeding the crude oil into a crude oil filter for physical filtration to obtain finished product oil, heating the finished product oil to 40-60 DEG C, cooling the finished product oil to 8-12 DEG C at a cooling rate of 0.5-1 DEG C/h, keeping the temperature at 8-12 DEG C for a period of time, and then performing filtering by a plate filter to obtain the edible sunflower seed oil. The provided production method of sunflower seed oil has the advantages that the oil yield can be increased, and the wax content of the edible sunflower seed oil is reduced.

Example Embodiment

[0047] Example 1

[0048] (1) Use a peeling machine to peel the collected sunflower seeds to obtain sunflower kernels;

[0049] (2) Dry the sunflower kernels for 40 minutes to obtain dried sunflower kernels;

[0050] (3) Press the dried sunflower kernels into sunflower kernel cakes of about 5kg, and put 20 pieces of sunflower kernel cakes into the hydraulic press for each pressing, and press the hydraulic press at a uniform speed through three stages. The first stage The pressure of the hydraulic press is adjusted to 80MPa and maintained for 30min. In the second stage, the pressure of the hydraulic press is adjusted to 140MPa and maintained for 80min. In the third stage, the pressure of the hydraulic press is adjusted to 280MPa and maintained for 40min. Press dried sunflower kernels to obtain crude oil;

[0051] (4) Input the crude oil into the crude oil filter for physical filtration to obtain product oil;

[0052] (5) Heat the product oil to 50°C, then cool it to 10°C at a cooling rate that drops 0.5°C per hour, keep it at 10°C for 15 hours, and filter through a plate filter to obtain edible sunflower seeds oil.

Example Embodiment

[0053] Example 2

[0054] (1) Use a peeling machine to peel the collected sunflower seeds to obtain sunflower kernels;

[0055] (2) Dry the sunflower kernels for 40 minutes to obtain dried sunflower kernels;

[0056] (3) Press the dried sunflower kernels into sunflower kernel cakes of about 5kg, and put 20 pieces of sunflower kernel cakes into the hydraulic press for each pressing, and press the hydraulic press at a uniform speed through three stages. The first stage The pressure of the hydraulic press is adjusted to 90MPa and maintained for 30min. In the second stage, the pressure of the hydraulic press is adjusted to 150MPa and maintained for 80min. In the third stage, the pressure of the hydraulic press is adjusted to 290MPa and maintained for 40min. Press dried sunflower kernels to obtain crude oil;

[0057] (4) Input the crude oil into the crude oil filter for physical filtration to obtain product oil;

[0058] (5) Heat the product oil to 50°C, then cool it to 10°C at a cooling rate that drops 0.5°C per hour, keep it at 10°C for 15 hours, and filter through a plate filter to obtain edible sunflower seeds oil.

[0062] (3) Press the dried sunflower kernels into sunflower kernel cakes of about 5kg, and put 20 pieces of sunflower kernel cakes into the hydraulic press for each pressing, and press the hydraulic press at a uniform speed through three stages. The first stage The pressure of the hydraulic press is adjusted to 100MPa and maintained for 30min. In the second stage, the pressure of the hydraulic press is adjusted to 160MPa and maintained for 80min. In the third stage, the pressure of the hydraulic press is adjusted to 300MPa and maintained for 40min. Press dried sunflower kernels to obtain crude oil;

[0063] (4) Input the crude oil into the crude oil filter for physical filtration to obtain product oil;

[0064] (5) Heat the product oil to 50°C, then cool it to 10°C at a cooling rate that drops 0.5°C per hour, keep it at 10°C for 15 hours, and filter through a plate filter to obtain edible sunflower seeds oil.
