Abstract
The rubber seed oil extracting process with high oil yield includes the following steps: stoving rubber seed to water content of 5-15 %, crushing and wind selecting to obtain rubber seed kernel with rubber seed hull content of 20-50 %, heating to 30-120 deg.c, squeezing in squeezer to obtain coarse oil and seed cake, refining coarse oil, puffing the seed cake, leaching the puffed seed cake to obtain mixed oil, evaporating the mixed oil to eliminate solvent and obtain rubber seed oil. The present invention combines oil squeezing and oil leaching, and has high oil yield.
Description
Technical field
The present invention relates to a kind of extracting method of rubber seed oil, belong to the oil plant processing technique field.
Background technology
Oil length is higher in the rubber seed benevolence, and the composition of lipid acid is based on unsaturated fatty acidss such as oleic acid, linolic acid, linolenic acid in the oil.Being of high nutritive value, is a kind of new oil species with edibleness.But the rubber seed oil-producing technique is backward in technique at present, and industrialized scale is little, has seriously hindered the development and use of rubber seed resource.Produce squeezing reparation technology, residual oil content height, the deficiencies in economic performance of adopting at present more.If adopt pre-the press for extracting juice to leach reparation technology, in leaching process, materials such as the rubber in the rubber seedcake, resin, colloid can be extracted, oil viscosity is increased, and be easy to stop up sieve plate, make lixiviate to carry out.
Summary of the invention
The object of the present invention is to provide a kind of extracting method of rubber seed oil, this method is easy to lixiviate and refining, and Residual oil is lower in the dregs of rice, and the oil yield of rubber seed is higher, and the rubber seed oil color and luster that extracts is good, impurity is few.
For achieving the above object, technical scheme provided by the invention is: the extracting method of rubber seed oil, rubber seed is dried earlier, and make moisture reach 5%-15%, after fragmentation, selection by winnowing, obtain to contain the rubber seed benevolence of rubber seed hull 20%-50%; Send in the squeezing machine after rubber seed benevolence being heated to 30 ℃-120 ℃ again and squeeze; Obtain crude oil and rubber seedcake after the squeezing, crude oil is collected the back refining.Rubber seedcake is carried out puffing at 80 ℃-180 ℃ obtain expanded cake, then expanded cake is carried out lixiviate, the mixing oil that lixiviate obtains gets rubber seed oil behind the evaporation precipitation.
The used extraction solvent of above-mentioned lixiviate is hexanaphthene, normal hexane, ether or No. six solvents; The consumption weight ratio of expanded cake and extraction solvent is 1: 1～6, and extraction time is 10～300 minutes, and extraction temperature is 10 ℃～80 ℃.
The present invention adopts the processing method of the expanded leaching of rubber seed cold press, and cold press obtains a part of crude oil after handling, and its phospholipids content and impurity all seldom are easy to refining.Cake after the cold press is through after the puffing, and the cake quality is loose, is well suited for the solvent lixiviate.After handling through high temperature puffing, colloid material such as part phosphatide in the rubber seed and rubber and harmful prussiate have decomposed, and when having avoided the lixiviate of rubber seedcake, colloid materials such as rubber are extracted out the phenomenon of stopping up sieve plate, and have removed objectionable impurities well.
The used extraction solvent of lixiviate of the present invention adopts non-polar solvent, and the prussiate in the rubber seed benevolence dregs of rice after the lixiviate is removed, can directly adopt for feed.
The present invention drops to about 1% the residual oil content in the rubber seed dregs of rice.
The invention solves that crude oil is difficult to the purified problem in the single pressing reparation technology; Also avoided pre-press for extracting juice to leach that materials such as the rubber in the rubber seedcake, resin, colloid are extracted out the phenomenon of stopping up sieve plate in the reparation technology; Reduce Residual oil in the dregs of rice, improved the oil yield of rubber seed.The present invention can make that a kind of color and luster is yellowish, impurity is few, has the grease of rubber seed peculiar taste.
