Abstract
The present invention relates to a method for preparing natural oil by peeling and cold pressing rapeseeds, which comprises technical processes of cleaning rapeseeds, squeezing rapeseeds, etc. The rapeseeds are dried at the low temperature below 50 DEG C to make the moisture content of the rapeseeds be from 3% to 8%(W/W); the moisture content of nuts obtained by peeling the rapeseeds is from 3% to 9%(W/W), and the temperature of the nuts is from 5 DEG C to 35 DEG C by moisture content regulation and temperature regulation. The cold pressing temperature for the rapeseed nuts is below 60 DEG C, the compression ratio of a cold pressing machine is from 14 to 35, and the pressing rime is from 4 to 12 min.
Description
The invention belongs to the Vegetable oil lipoprotein processing technique field, be applicable to the processing of decortication oil plant, particularly be suitable for the preparation method of the decortication cold press rapeseed oil of double-low rapeseed seed.
Double-low rapeseed seed (content of erucic acid＜5%, sulphur glycosides content＜40 μ mol/g) is the fine vegetable oil material.Rapeseed oil preparation method as prior art is; Vegetable seed is made rapeseed oil through clearing up, soften, roll embryo, steaming stir-fry, pre-press for extracting juice, leaching and refining.It is low that this method has a dregs of rice Residual oil, the oil yield advantages of higher.But also exist complex process, equipment used is many, does not slough the kind skin of vegetable seed.Particularly can produce some to the disadvantageous material of human body, but also the natural active matter in the grease is run off at refining process.
Purpose of the present invention just is to provide a kind of: technology is simple, and used processing units is few, and finished product have kept the preparation method of the decortication cold press rapeseed oil of pure natural oil property.
Purpose of the present invention can realize by following technique measures.Semen Brassicae campestris is after the cleaning removal of impurities, use the drying plant warm air drying, vegetable seed temperature＜50 ℃, vegetable seed moisture is 3%-5%, sloughs kind of a skin with dejacketer then, benevolence after the decortication is carried out moisture and temperature regulation through quality controling machine, make that moisture is at 3%-9% in the benevolence, temperature is 5 ℃-35 ℃, goes into the oil press zhai squeezing subsequently and gets oil, oil press zhai has bigger compression ratio and squeezing time, can adopt the way of lengthening oil extruder thorax or adopt the way of twice pressing to realize.The oil that squeezes out promptly makes the natural edible rapeseed oil through precipitation, fine filtering.
The advantage that the present invention had:
1, adopts decortication, cold pressing process, can make natural high-quality edible rapeseed oil.
2, simple, scientific and reasonable, the non-environmental-pollution of technology.
3, owing to do not need refining, the natural active matter in the oil keeps.Do not produce harmful material.
4, protein unchangeability in the cold pressed cake can further develop.
Embodiment further describes the present invention below in conjunction with accompanying drawing.
Accompanying drawing is technical process of the present invention.
Accompanying drawing and subordinate list are embodiments of the invention.
Semen Brassicae campestris is removed various impurity through cleaning equipment, and cleaning back raw material does not contain stone and irony material, and foreign matter content is less than 0.5%.Use the drying plant warm air drying, the vegetable seed temperature is removed the moisture in the vegetable seed less than 50 ℃ when dry, makes moisture content reduce to 3%-5%.Through dejacketer the benevolence skin is separated then, dejacketer selects machine to form by a pair of discaling roll and vibratory screening apparatus and two typhoons, and dried vegetable seed carries out the benevolence skin by vibratory screening apparatus and winnowing machine and separates through the discaling roll fragmentation, reach and contain skin in the benevolence, contain benevolence in the skin less than 4% effect less than 5%.Benevolence after the decortication is carried out the adjusting of moisture and temperature through quality controling machine, make that moisture reaches 3%-9% in the benevolence, 5 ℃-35 ℃ of temperature, carry out expeller subsequently and get oil, the structural principle of oil press zhai and general oil press zhai are basic identical, but ideal theoretical compression ratio is bigger, in the scope of 14-35, the squeezing time is longer, the scope at 4-12 minute.The oil that squeezes out is natural edible oil through sedimentation, fine filtering.The cake that squeezes out and isolated kind of skin are sent to leaching.
Subordinate list is the optimal processing parameter of embodiment
