Problems solved by technology

[0003] Compared with other vegetable oil raw materials, the cellulose content of safflower seed material is as high as 33%, and the shell hardness is relatively high. During the oil pressing process, the high crude fiber content of the seed coat is too high, resulting in an excessively large friction factor, which is not conducive to the pressing process of the pressed material. The conveying in the bore may easily cause accidents such as bursting of the press chamber
In addition, in the traditional pressing process, due to the

Embodiment Construction

[0012] The present invention is described in further detail below in conjunction with embodiment.

[0013] The process of the safflower seed cold pressing method for oil production of the present invention is as follows:

[0014] Impurities removal: The safflower seed raw material is sent to the flat rotary screen by the scraper elevator, and then sent to the specific gravity destoner after screening to remove the side stones (sandstones similar in shape and size to the safflower seeds) in the safflower seeds.

[0015] Crushing: The safflower seeds after removing impurities are sent to the double-roller crusher, crushed and crushed under the extrusion action of a pair of oppositely rotating round rollers, mainly to break the shell of the safflower seeds, and the crushed safflower seeds should not be larger than 5 mm, preferably The control is around 0.5 mm.

[0016] Conditioning: The broken and qualified safflower seeds are sent to the conditioning pot, water is atomized and ...

Abstract

The invention discloses a method for producing oil from safflower seeds through cold pressing. The method comprises the following steps: (1) crushing: crushing the safflower seeds until the safflower seeds are no greater than 5 mm; (2) modification: a step of wetting the safflower seeds crushed in the step (1) with water to allow the moisture of the safflower seeds to be 7.5 to 8.5 wt%; and (3) pressing: a step of feeding the modified safflower seeds into an oil press and carrying out pressing so as to obtain safflower seed oil. According to the invention, explosion of a press chamber caused by too high cellulose content and hard shells of the safflower seeds is prevented, the problem of deterioration caused by high temperature since temperature rapidly rises due to accumulation of frictional heat during pressing is avoided, loss of oil and nutritional components in a safflower seed cake during processing is reduced, and the content of protein in the safflower seed cake is increased.

Description

technical field [0001] The invention belongs to the field of vegetable oil extraction, and in particular relates to a method for producing oil by cold pressing of safflower seeds. Background technique [0002] The cold pressing process is an oil production process with less impact on the environment. Due to the ultra-low temperature cold pressing technology used in the cold pressing process, the obtained cold pressed oil meets the requirements of direct consumption without further oil refining. After filtering, the finished cold-pressed oil has pure natural characteristics, which avoids the adverse effects of traditional leaching oil processing plants. The cold-pressed finished oil retains the natural flavor and color of the oil, and completely preserves the physiologically active substances in the oil ( Such as vitamin E, sterols), the by-products of oil pressing cold-pressed cake can be pressed twice or used as an important raw material for the production of feed.
