Embodiment 1

[0016] A cold pressing process of compound flax oil, comprising the following process steps:

[0017] (1) Screening: flax seeds and rapeseed are used as raw materials, and the raw materials are screened, that is, impurities such as weeds, soil, stones and broken iron are removed from the raw materials by using vibrating screens, stone removers and magnetic separators.

[0018] (2) Drying: Spread the screened raw materials into a layer to be dried with a thickness of 7cm, and dry them at 35°C for 4 to 5 days. At the same time, during the drying process, the raw materials are constantly turned to make them The drying is more fully, comprehensively and evenly.

[0019] (3) Mixing: mix the dried flax seeds and rapeseed according to the mass ratio of 1:1 and stir evenly to obtain a mixture.

[0020] (4) Pulverization: the mixture is pulverized into powder in a high-speed pulverizer, and the particle size of the powder is 10 μm˜15 μm.

[0021] (5) Add brine: add brine with a conce...

Embodiment 2

[0026] A cold pressing process of compound flax oil, comprising the following process steps:

[0027] (1) Screening: Use flax seeds and sunflower seeds as raw materials, and screen the raw materials, that is, use vibrating screens, stone removers and magnetic separators to remove impurities such as weeds, soil, stones and broken iron in the raw materials.

[0028] (2) Drying: Spread the screened raw materials into a layer to be dried with a thickness of 5cm, and dry them at 40°C for 3 to 4 days. At the same time, during the drying process, the raw materials are constantly turned to make them The drying is more fully, comprehensively and evenly.

[0029] (3) Mixing: mix the dried flax seeds and sunflower seeds according to the mass ratio of 1:1 and stir evenly to obtain a mixture.

[0030] (4) Pulverization: the mixture is pulverized into powder in a high-speed pulverizer, and the particle size of the powder is 10 μm˜15 μm.

[0031] (5) Add brine: add brine with a concentrati...

Embodiment 3

[0036] A cold pressing process of compound flax oil, comprising the following process steps:

[0037] (1) Screening: Use flax seeds and sunflower seeds as raw materials, and screen the raw materials, that is, use vibrating screens, stone removers and magnetic separators to remove impurities such as weeds, soil, stones and broken iron in the raw materials.

[0038] (2) Drying: Spread the screened raw materials into a layer to be dried with a thickness of 15cm, and dry them at 40°C for 5 days. At the same time, during the drying process, the raw materials are continuously turned to make them dry more fully and evenly.

[0039] (3) Mixing: mix the dried flax seeds and sunflower seeds according to the mass ratio of 3:7 and stir evenly to obtain a mixture.

[0040] (4) Pulverization: the mixture is pulverized into powder in a high-speed pulverizer, and the particle size of the powder is 15 μm to 20 μm.

[0041] (5) Add brine: add brine with a concentration of 12% to the pulverize...

Abstract

The invention belongs to the technical field of edible oil processing, and relates to a cold pressing technology for composite flaxseed oil. The cold pressing technology includes the following steps:1, using and screening of flax seeds and composite plant seeds as raw materials; 2, drying; 3, mixing of the raw materials in proportion; 4, crushing using a high speed crusher; 5, addition of brine,and standing; 6, pressing using a hydraulic oil press; and 7, separation using a high speed centrifuge to obtain the composite flaxseed oil. The cold pressing technology for composite flaxseed oil hasthe advantages of safety, no pollution, low operation cost and high oil yield, and the pressed product oil has the advantages of effectiveness in maintaining of the nutritional values of the flax seeds, good taste, good quality and wide suitable public range.

Description

technical field [0001] The invention belongs to the technical field of edible oil processing, and relates to a cold pressing process of compound flax oil. Background technique [0002] Flax oil is a fatty oil extracted from the linseed seeds of cucurbita. It is rich in α-linolenic acid and various unsaturated fatty acids, which can be directly converted into DHA and EPA in the human body. It is an economical "deep-sea fish oil". It has the functions of strengthening the brain, promoting intelligence, lowering blood fat and preventing thrombosis. Because flax is cold-loving and resistant to cold, it is suitable for survival in cold regions. Therefore, residents living in the north have a higher acceptance of flax oil. With the gradual development of information communication and transportation, the nutritional value and health care function of flax oil have gradually received more and more attention. However, the α-linolenic acid in flax oil has a pungent taste, and the oil...
