Embodiment 1

[0011] Example 1 Take rubber seeds and dry them until the moisture content of the shells is about 6%, then crush them, and winnow the rubber seed kernels containing 35% of the rubber seed shells. Oil and rubber seed cake. The rubber seed cake was puffed at 110°C, and the rubber seed cake obtained after pressing and puffing was put into a 1000mL extractor, and cyclohexane was added according to the weight ratio of the puffed cake to the extraction solvent of 1:2. Insulated at 55° C., soaked for 20 minutes, and extracted three times in this way, the residual oil rate in the rubber seed cake was measured to be 0.83%. The obtained mixed oil is evaporated and precipitated under vacuum condition to obtain the extracted rubber seed oil. The extracted rubber seed oil is light yellow in color, less impurity, and has the unique flavor of rubber seeds.

Embodiment 2

[0012] Example 2, the rubber seeds were dehydrated until the moisture content of the shell was about 8%, then crushed, and the rubber seed kernels containing 38% of the rubber seed shells were obtained by winnowing, and then the rubber kernels were tempered to 60°C, and then squeezed to collect the rubber seeds. Oil and rubber seed cake. The rubber seed cake is puffed at 130°C, and the pressed and expanded rubber seed cake is put into a 1000mL extractor, and n-hexane is added according to the weight ratio of the puffed cake to the extraction solvent of 1:1.5. Insulated at 50° C., soaked for 20 minutes, and extracted three times in this way, the residual oil rate in the rubber seed cake was measured to be 0.88%. The mixed oil is precipitated under vacuum conditions to obtain rubber seed oil. The extracted rubber seed oil is light yellow in color, less impurity, and has the unique flavor of rubber seeds.

Embodiment 3

[0013] Example 3, the rubber seeds were dehydrated until the moisture content of the shells was about 10%, then crushed, air-selected to obtain rubber seed kernels containing 41% of the rubber seed shells, and then the rubber seeds were tempered to 80°C, and then squeezed and collected Crude oil and rubber seed cake. The rubber seed cake was puffed at 150°C, and the pressed and puffed rubber seed cake was put into a 1000mL extractor, and diethyl ether was added according to the weight ratio of puffed cake to extraction solvent of 1:1.5. Insulated at 50° C., soaked for 30 minutes, and extracted three times in this way, the residual oil rate in the rubber seed cake was measured to be 0.9%. The mixed oil is precipitated under vacuum conditions to obtain rubber seed oil. The extracted rubber seed oil is light yellow in color, less impurity, and has the unique flavor of rubber seeds.

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 [0001] The invention relates to a method for extracting rubber seed oil, belonging to the technical field of oil processing. Background technique [0002] The oil content in the rubber seed kernel is relatively high, and the composition of fatty acids in the oil is mainly unsaturated fatty acids such as oleic acid, linoleic acid, and linolenic acid. It has high nutritional value and is a new oil species with edible value. However, the current rubber seed oil production technology is backward, and the industrialization scale is small, which seriously hinders the development and utilization of rubber seed resources. At present, most of the production adopts the pressing process, which has a high residual oil rate and poor economic benefits. If the pre-pressing leaching process is used, the rubber, resin, colloid and other substances in the rubber seed cake will be extracted during the leaching process, which will increase the viscosity of the oil, and it will...
