Embodiment 1

[0042] Take 60kg of sunflower seeds, dry them to a moisture content of 4%, and then shell them to obtain sunflower kernels; use a flaking machine to process the sunflower kernels to obtain sunflower embryos with a particle size of 1mm, and heat them at 70°C Steam the sunflower seed embryos for 5 minutes to soften the sunflower seed embryos;

[0043] The softened sunflower seed embryo is pre-pressed for 20 minutes with an automatic cake-removing hydraulic oil press under the condition of a maximum pressure of 25 MPa to obtain a sunflower seed cake, and the oil content of the sunflower seed cake is 16%;

[0044] Sunflower seed cake is pulverized into particle diameter and is the broken cake granule of 4mm, then the broken cake granule is sent into screw oil press and pressed for 5 minutes to obtain primary sunflower seed oil (crude oil), and then the primary sunflower seed oil is Refining is carried out to obtain finished sunflower seed oil.

Embodiment 2

[0047] Take 80kg of sunflower seeds, dry them to a moisture content of 8%, and then shell them to obtain sunflower kernels; use a flaking machine to process the sunflower kernels to obtain sunflower embryos with a particle size of 2mm, and heat them at 90°C Steam the sunflower seed embryos for 4 minutes to soften the sunflower seed embryos;

[0048] The softened sunflower seed embryos were pre-pressed for 30 minutes with an automatic cake-removing hydraulic oil press under the condition of a maximum pressure of 20 MPa to obtain a sunflower seed cake, and the oil content of the sunflower seed cake was 6%;

[0049] The sunflower seed cake was crushed into broken cake particles with a particle size of 6 mm, and then the broken cake particles were sent to a screw oil press for pressing for 10 minutes to obtain primary sunflower seed oil.

Abstract

The invention provides a method for squeezing sunflower seed oil. The method comprises the steps: (1) drying sunflower seeds, and hulling the dried sunflower seeds so as to obtain sunflower seed kernels; (2) performing germ flattening on the sunflower seed kernels so as to obtain sunflower seed cakes, and steaming the sunflower seed cakes with water vapor so as to obtain softened sunflower seed cakes; and (3) performing pre-squeezing and second squeezing sequentially on the softened sunflower seed cakes so as to obtain the sunflower seed oil. The method for squeezing the sunflower seed oil hasthe advantages of simple and convenient operation and a high oil yield.

Description

technical field [0001] The invention relates to the field of edible oil, in particular to a method for squeezing sunflower oil. Background technique [0002] Sunflower oil does not contain erucic acid, cholesterol, aflatoxins and other additives. The unsaturated fatty acid in sunflower seed oil is as high as more than 90%, oleic acid reaches 80-83%, linoleic acid reaches 7-13%, and is rich in protein and vitamins A, B, D, E, etc., especially it contains The rich linolenic acid is necessary but cannot be synthesized by the human body. The content of oleic acid and linoleic acid in sunflower seed oil is higher than that of olive oil, so it has the reputation of "Oriental olive oil". Sunflower seed oil contains a variety of functional ingredients. Long-term consumption has obvious effects of preventing cardiovascular sclerosis, lowering blood pressure, lowering blood fat, etc., and has special effects of preventing and fighting cancer. [0003] With the improvement of people...
