Abstract

The invention relates to a high oil-content oil material expanding prepressing leaching oil preparation method, which is characterized in that the method comprises the following steps, firstly, cleaning, cleaning oiling to remove impurities, secondly, tempering, adjusting the water content of oiling whose impurities are removed, thirdly, rolling slab, rolling oiling whose water content is adjusted into material slab, fourthly, squeezing and swelling, squeezing and swelling, the material slab, fifthly, drying, drying the material slab which is squeezed and swelled, sixthly, prepressing, prepressing the material slab which is dried to press one portion of oil, seventhly, leaching, leaching prepressed cake of the oil which is prepressed to get another portion of oil and meal from solvent extraction. A squeezing and swelling step in the invention is utilized to replace a cooking step in the existing method, which improves the quality and amounts of prepressing crude palm oil, increases handling capacity of a prepress expeller, and reduces power consumption and abrasion of a prepress expeller. The method of the invention is mainly applicable for oil preparation enterprises which utilize high oil-content oiling such as rapeseed and the like to be raw material.

Description

technical field [0001] The invention relates to a method for preparing oil from oil-containing oil, in particular to a method for producing oil by puffing, pre-pressing, and leaching of high-oil-containing oil. Background technique [0002] Vegetable oils can be divided into high oil content and low oil content according to oil content; high oil content includes rapeseed, cottonseed, linseed, sunflower seed, etc., and high oil content generally contains more than 25% oil; low oil content includes soybean, rice bran, etc. , Generally, the oil content is below 25%. The oil-making process of the above-mentioned high oil content oil and low oil content oil is different. [0003] In the current method of producing oil from high-oil-containing oil, the traditional process is generally followed, that is, the oil-containing oil is cleaned, rolled, steamed, pre-pressed, and then leached. However, the traditional processing method has the following deficiencies. Take the method of p...
