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
The invention belongs to plant oil expression field, be specifically related to Semen Flos Carthami cold pressing oil method.
Background technology
Cold pressing process is a kind of oil-producing technique having fewer environmental impacts, and owing to having adopted very low temperature cold press technology in cold pressing process, the pressed oil obtaining meets directly edible requirement, and does not need further oil and fat refining.After filtering, obtain finished product pressed oil and there is pure natural characteristic, avoid the disadvantageous effect of traditional leaching oil expression process plants, in cold press processed oil, retain the natural flavour mountaineous and color and luster of oil plant, complete preservation physiologically active substance (as vitamin-E, sterol) in oil, the byproduct cold pressed cake of oil expression can twice pressing or as the important source material of producing feed.
Compared with other vegetable oil raw materials, Semen Flos Carthami material content of cellulose is up to 33%, and shell hardness is larger, high crude fiber content squeezing grease process mesosperm is too high, cause rubbing factor excessive, be unfavorable for squeezing material in the conveying of squeezing in thorax, easily cause accidents such as squeezing thorax explosion.In addition, in traditional expressing process due to squeeze material volume compression and distortion, squeezing material inside particles friction, squeeze material particle at the volley with the friction of crusher parts etc., can make heat accumulation cause squeezing material temperature degree raises, cause Semen Flos Carthami crude oil color and luster to deepen, nutritive ingredient in grease and the protein volatility in cake under high temperature, reduce the feeding value of grouts greatly simultaneously.
Summary of the invention
The object of the invention is to overcome the problem in existing Semen Flos Carthami oil expression, a kind of Semen Flos Carthami cold pressing oil method is provided.
It is as follows that the present invention realizes the technical scheme that above-mentioned purpose adopts:
Semen Flos Carthami cold pressing oil method, comprises,
(1) break process: Semen Flos Carthami is crushed to and is not more than 5 millimeters;
(2) modified: the Semen Flos Carthami with water-wet after step (1) fragmentation, makes Semen Flos Carthami moisture to 7.5-8.5wt%;
(3) Semen Flos Carthami after modified enters oil press zhai, and squeezing obtains safflower oil.
Further, step (1) adopts two rod crushers to carry out fragmentation to Semen Flos Carthami.
In the present invention, after Semen Flos Carthami fragmentation, make Semen Flos Carthami cell walls considerable damage, weaken intermolecular avidity, change the physical property of material, as rubbing factor, great changes will take place for perviousness etc., soaking by water again, utilize the strong polarity effect of water, further weaken the bonding force between differing molecular in cell walls, the particularly avidity of lipid and protein, because cell produces swollen through water infiltration, seed benevolence is more easily cohered agglomerating, pressure can be shaped a little, make false plastic deformation in advance, be conducive to the foundation as early as possible of oil extruder gun pressure power, avoid the explosion of squeezing thorax, because cell walls is destroyed in advance, simultaneously under the humidification of water, seed benevolence inside and the mutual friction of seed benevolence are reduced, while avoiding squeezing, gathering of heat of friction causes temperature to raise fast, the spoilage problems of having avoided high temperature to bring, the loss of grease and grouts nutritive ingredient in favourable minimizing processing, improve protein content in grouts.
Embodiment
Below in conjunction with embodiment, the present invention is described in further details.
Semen Flos Carthami cold pressing oil procedure of the present invention is as follows:
Impurity elimination: Semen Flos Carthami prepared using scraper lifting machine is sent into rotary flat sieve, sends into specific-gravity stoner again after screening, remove the stone shoulder to shoulder (sandstone approximate with Semen Flos Carthami shape size) in Semen Flos Carthami.
Broken: the Semen Flos Carthami after impurity elimination is sent into two rod crushers, attrition crushing under a pair of round roller squeezing action rotating in opposite directions, is mainly to make Semen Flos Carthami outer casing rupture, should be not more than 5 millimeters after fragmentation, is preferably controlled at 0.5 millimeter.
Modified: broken qualified Semen Flos Carthami particle is delivered to modified pot, water on Semen Flos Carthami particle, is controlled Semen Flos Carthami pellet moisture to 7.5-8.5wt% through atomized spray, in pot, overturn about 20min simultaneously, Semen Flos Carthami is soaked fully, blowing, drop temperature control is not higher than 40 DEG C.
Squeezing: the Semen Flos Carthami after modified is sent into duplex cold pressing expeller (XYZX24).Squeezing requires: cake is thick >=and 8 millimeters, cake oil length >=12%, squeezes fuel-displaced time≤30 second, and oil outlet temperature is less than 40 DEG C.The crude oil that squeezing obtains removes by filter large granular impurity through dragging for slag bath, the cake end of containing 2-4wt% in crude oil after filtering.
Upgrading: the crude oil after filtration is again through horizontal screw centrifuge centrifugal treating, and in centrifugal rear oil, solid formation granularity is less than 0.005mm, obtains finished product safflower oil.
Claims (2)
1. Semen Flos Carthami cold pressing oil method, comprises,
(1) break process: Semen Flos Carthami is crushed to and is not more than 5 millimeters;
(2) modified: the Semen Flos Carthami with water-wet after step (1) fragmentation, makes Semen Flos Carthami moisture to 7.5-8.5wt%;
(3) Semen Flos Carthami after modified enters oil press zhai, and squeezing obtains safflower oil.
2. Semen Flos Carthami cold pressing oil method according to claim 1, is characterized in that, step (1) adopts two rod crushers to carry out fragmentation to Semen Flos Carthami.
