Problems solved by technology

Therefore, although the oil produced by the oil pressing method is welcomed by people; but the disadvantage is that the oil yield is low, and the added value of the pressed cake is low; especially for oil extraction enterprises with small production scales, it is difficult to overcome the traditional process of oil extraction. The above shortcomings, it is not easy to occupy the market

Embodiment 1

[0043] Embodiment 1: For the production of small-scale output (30 tons / day to 50 tons / day) of oil-extracting rice bran with low oil content, adopt the technology of one-time pressing after puffing, and the steps in turn are:

[0044] 1) Cleaning: After the rice bran passes through the vibrating sieve and the bran and rice separator, the impurity content is less than 1%;

[0045] 2) Tempering: adjust the temperature and moisture of the cleaned rice bran, the temperature is 50°C, and the moisture content is 11%;

[0046] 3) Extrusion and puffing: carried out on YJP16 oil extrusion puffing machine, the moisture content of the flakes entering the puffing machine is 11%, the moisture content of the puffed material exiting the puffing machine is 13%, the puffing outlet temperature is 105°C, the puffing coefficient is 1.30; the steam pressure is 0.6 MPa.

[0047] 4) Enzyme killing and drying: Enzyme killing and drying are carried out in a layered evaporator at a temperature of 120°C...

Embodiment 2

[0048] 5) Pressing: use a press to press the dried puffed material to obtain crude oil, the temperature of entering the pressing is 105°C, the moisture is 6% when entering the pressing, and the residual oil in the pressed cake is 7%. The crude oil is extracted and filtered to become pressed clear oil. Embodiment 2: use the method of the present invention to the oil production of soybean small-scale output (50 tons / day~150 tons / day), adopt the technology of squeezing once after expanding, and the steps in turn are:

[0049] 1) Cleaning: After the soybeans pass through vibrating sieves, stone removers, magnetic separators, and winnowing, the impurity content is less than 1%;

[0050] 1A) Crushing: After the soybeans are crushed by a toothed roller crusher, the crushed particle size is 4 to 6 petals, and the powder degree of the crushed beans is no more than 10% of the powder passing through a 20 mesh / inch sieve.

[0051] 2) Tempering: the tempering temperature is 60° C., and th...

Embodiment 3

[0056] Embodiment 3: use the method of the present invention to the oil-making production of soybean small-scale output (50 tons / day~150 tons / day), adopt the technology of one time squeezing after puffing, successive steps are:

[0057] 1) Cleaning: After the soybeans are subjected to vibrating sieves, stone removers, magnetic separators, and winnowing, the impurity content is less than 1%;

[0058] 1A) Crushing: After the soybeans are crushed by a toothed roller crusher, the crushed particle size is 4 to 6 petals, and the powder degree of the crushed beans is controlled to be no more than 10% of the powder passing through a 20 mesh / inch sieve.

[0059] 2) Tempering: the tempering temperature is 70° C., and the moisture content of the material after conditioning is 9%.

[0060] 2A) Billet rolling: the thickness of the billet is 0.5mm;

[0061] 3) Expansion: carried out on a YJP16 oil extrusion extruder, the moisture content of the flakes entering the extruder is 9%, the moist...

Abstract

The invention relates to a method for extracting oil by swelling and pressing low oil content oil seeds and is characterized by comprising the following steps: 1) clearing: impurities are removed from the oil seeds; 2) quality-adjusting: the temperatures and water contents are adjusted for the oil seeds; 3) the oil seeds are pressed and swelled; 4) enzyme killing and drying are carried out for the pressed and swelled oil seeds; 5) most of the oil is pressed from the dried oil seeds; the oil seeds can be crushed and then the quality adjusting can be done after the clearing of the step 1); after the step 2) of quality-adjusting, the bloom rolling can be done to the oil seeds and then the pressing and swelling can be done. The method adds the procedures of pressing and swelling before the traditional one time pressing and obtains pure physical pressed oil with high quality and pressed cakes which can be directly used for feed processing, which increases the processing amount of a press and reduces the power consumption and wearing. The method is mainly used for producing small-scale pressed oil and pressed cakes with good qualities and raw materials of low oil content oil seeds such as soybeans and rice bran.

Description

technical field [0001] The invention relates to a method for producing oil by pressing oily materials, in particular to a method for producing oil by extruding oil materials with low oil content. Background technique [0002] In the oil industry that extracts oil from oily oilseeds, oily vegetable oilseeds are generally divided into low oily and high oily plants according to their oil content. Peanuts, rapeseeds, cottonseeds, sunflower seeds, etc. have an oily content of more than 25%. For high oil content, the pre-pressing-extraction method is usually used to produce oil; for oil content less than 25%, such as soybeans and rice bran, which are called low oil content oil plants, usually pretreatment and direct extraction are used to produce oil. [0003] The pressing method is to apply physical pressure to separate the oil from the oil without adding any chemical substances. The various components in the squeezed oil remain relatively intact, but the disadvantage is that the...
