Walnut oil content as high as 65 ~ 70%, and rarely fibrous substances, so the system of pressing oil is difficult.If you don't add other supplementary materials, squeezing squeezed oil cannot reach the required pressure in the chamber, walnut cake and walnut oil cannot be separated, and the jam squeezed out together, can't prepare in walnut oil, in order to overcome this problem,palm oil processing plantthe mechanism of screw press can be used in walnut oil, added in the walnut kernel part of the nuclear pick shells, walnut oil so it is easier to squeeze out, but will bring the impurities in the extract oil too much, more important is walnut cake can not be recycled.
The traditional system of hydraulic oil, walnut oil can be produced, but the intensity of labor is big, efficiency is low, unable to realize industrialization production.1995, Wu Biqin et al developed by using kernel separator for nuclear cut out after the raw materials for processing, then walnut walnut oil by two cold squeezing produced.The method processing route short, bucket elevatorsimple equipment is easy to operate, less investment, quick effect, walnut oil nutrients intact, oil quality, unique flavor, solvent residue.2004 ke-jian wang reports such as walnuts after peeling, drying, crushing treatment by using hydraulic extraction of walnut oil on craft is completely feasible.Walnut cake in residual oil rate below 8%, each index of the walnut oil obtained after refining in conformity with the relevant standards of the state: such as substrate don't need to add in the process of machining hard shell, by controlling the pressure, squeeze times and squeeze time to effectively control the extraction yield of walnut, make nonfat walnut cake conform to the needs of the specific processing.
