Embodiment 1

[0032] The concrete steps of the cold-pressed oil method provided by the invention are as follows:

[0033] 1) Put the oil raw material cottonseed into the wind seed cleaning machine to clean light impurities, heavy impurities and short fibers;

[0034] 2) Use a double pair of gear peeling machine for shelling, and then use a stepped shell-kernel separator to separate the shell kernels;

[0035] 3) The shell kernel mixture obtained in step 2) is flaked with a flaking machine, so that the shell kernel mixture becomes a material embryo suitable for oil production;

[0036] 4) Put the raw material into the RHGN softening pot (airflow softening pot: Henan Zhengzhou Lide Grain and Oil Technology Co., Ltd.) for softening, softening for 30 minutes, the discharge temperature is 60°C, and the moisture content in the raw material is 6-10% when discharging ;Adopt the above softening conditions, will not change the nutrients in the material, retain the nutrients to the greatest extent, a...

Embodiment 2

[0049] The concrete steps of the cold-pressed oil method provided by the invention are as follows:

[0050] 1) Put the oil raw material sunflower seeds into the wind seed cleaning machine to clean light impurities, heavy impurities and short fluff;

[0051] 2) Use a double pair of gear peeling machine for shelling, and then use a stepped shell-kernel separator to separate the shell kernels;

[0052] 3) The shell kernel mixture obtained in step 2) is flaked with a flaking machine, so that the shell kernel mixture becomes a material embryo suitable for oil production;

[0053] 4) Put the raw material into the RHGN softening pot (airflow softening pot: Henan Zhengzhou Lide Grain and Oil Technology Co., Ltd.) for softening, softening for 30 minutes, the discharge temperature is 60°C, and the moisture content in the raw material is 6-10% when discharging ;Adopt the above softening conditions, will not change the nutrients in the material, retain the nutrients to the greatest exten...

Embodiment 3

[0067] The concrete steps of the cold-pressed oil method provided by the invention are as follows:

[0068] 1) Put the oil raw material peanuts into the wind seed cleaning machine to clean light impurities, heavy impurities and short fluff;

[0069] 2) Use a double pair of gear peeling machine for shelling, and then use a stepped shell-kernel separator to separate the shell kernels;

[0070] 3) The shell kernel mixture obtained in step 2) is flaked with a flaking machine, so that the shell kernel mixture becomes a material embryo suitable for oil production;

[0071] 4) Put the raw material into the RHGN softening pot (airflow softening pot: Henan Zhengzhou Lide Grain and Oil Technology Co., Ltd.) for softening, softening for 30 minutes, the discharge temperature is 60°C, and the moisture content in the raw material is 6-10% when discharging ;Adopt the above softening conditions, will not change the nutrients in the material, retain the nutrients to the greatest extent, and m...

Abstract

The invention provides a cold oil pressing method. The method comprises the following steps: (1) cleaning raw oil; (2) husking the raw oil to separate husks from kernels; (3) performing flaking to obtain a material blank; (4) softening the material blank; (5) performing cold pressing on the material blank; (6) precipitating the material blank, filtering oil, and collecting a leach liquor to obtain crude oil; and collecting a precipitate to obtain a filter cake; (7) adjusting the acid value of the crude oil till the pH value is less than or equal to 3; (8) centrifuging the crude oil obtained in the step (7), and stopping centrifuging after an index is reached; and (9) deodorizing the centrifuged crude oil, and performing inspection to obtain a refined oil product after the inspection is passed. The refined oil product prepared by using the cold oil pressing method provided by the invention can well keep nutrient substances in the raw oil, the oil and the oil cake do not change color, and meanwhile energy is saved; obtained protein meal is golden yellow; and compared with the conventional process, the cold oil pressing method has the advantages that the protein digestibility of low-temperature cottonseed meal is increased greatly, the gossypol content is lowered greatly, and damages to animal health are reduced while nutrients are increased.

Description

technical field [0001] The invention relates to a method for cold pressing oil. Background technique [0002] At present, most enterprises use the hot pressing method to extract vegetable oil, which will destroy the active ingredients of the oil during the hot pressing process, and due to the high temperature in the hot pressing process, the energy consumption is very large. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a method for cold pressing oil, the method will not destroy the effective components of the oil, and the cold pressing process has low energy consumption and saves energy. [0004] In order to realize the foregoing invention object, the technical scheme that the present invention adopts is as follows: [0005] The invention provides a method for cold pressing oil, the steps are as follows: [0006] (1) Clean up oil raw materials; [0007] (2) Peel off the shell and separate the shell an...
