Abstract
The invention, belonging to the technical field of energy sources, particularly relates to an extraction technology of seed oil. The extraction technology has the advantages of simpleness and high extraction rate. The extraction technology disclosed herein comprises the following steps: breaking shells of the seeds of shinyleaf yellowhorn, then taking the nuts, drying the nuts at 80 DEG C, then crushing the dried nuts into powder with the particle size of 0.5-5mm, filtering, then using petroleum ether with the ratio of material to solvent being 1:5-1:9 to extract in thermostat water bath for 4-12 h at 70-90 DEG C, and then using a rotary evaporimeter to recover the solvent.
Description
Technical field:
The invention belongs to energy technology field, more particularly, relate to a kind of extraction process of seed oil.
Background technology:
Wood of Shinyleaf Yellowhorn (Xanthoceras sorbifolia Bunge.) has another name called pawpaw, Wendeng City's pavilion, monk's lamp hair road, is under the jurisdiction of the Sapindaceae Wood of Shinyleaf Yellowhorn and belongs to, and is autogenus, deciduous tree or shrub.Originate in northern China, be distributed in 33 °～460 ° of north latitude, 100 °～125 ° of east longitudes, the Qinling Mountains, North of Huai River on the south the Inner Mongol, from the east of Liaoning, are taught to green grass or young crops, reach Henan and Along North Jiangsu in the south.Wood of Shinyleaf Yellowhorn is good woody oil tree species, have bear fruit early, output is high, oil yield is high, oil product is good characteristics.The seed oil length is up to more than 60%, contain protein 25.75%, robust fibre 1.6%, 3.739 maos of non-nitrogen materials, contain multiple lipid acid in its oil content, mainly contain linolic acid 42.9%, oleic acid 30.4%, palmitinic acid 5.0%, stearic acid 2.0%0 Wood of Shinyleaf Yellowhorn are not only and have been contained by the large woody oil tree species of amount, also be greening, beautify the ornamental plantation seeds, the bright Na of its tree performance, blade profile is graceful, pattern is magnificent, evening at florescence and length, seed oil have again pharmaceutical use, classify again at present national woody oil fuel energy Main tree as.
At present, the Global Oil resource reduces gradually, faces exhausted crisis, thereby, greatly develop the renewable energy source that comprises biomass energy and have important strategic importance.The production of biofuel has become the focus that countries in the world are paid close attention to.Biofuel is a kind of high-quality petroleum supplements of cleaning, has that air pollutant emission is few, oilness good, biological degradation waits advantage fully, is restricting its development but equipment requirements is high, extraction yield is low always.
Summary of the invention:
The present invention is exactly for the problems referred to above, and a kind of seed oil extraction process easy, that extraction yield is high for preparing is provided.
In order to realize above-mentioned purpose of the present invention, processing step of the present invention is: after the broken shell of Wood of Shinyleaf Yellowhorn seed, get kernel and after 80 ℃ of oven dry, be ground into the powder that particle diameter is 0.5～5mm, filter, then take sherwood oil in thermostat water bath the extracting of solid-liquid ratio as 1: 5～1: 9, extracting temperature is 70～90 ℃, and extraction time is 4～12h, reclaims solvent with Rotary Evaporators after the extracting.
Beneficial effect of the present invention:
1. extraction yield of the present invention wants high than traditional method, and average oil yield reaches 62.49%;
2. the present invention can be used as the new source of biodiesel raw material, for the production of the alternative fuel of petrifaction diesel take the Wood of Shinyleaf Yellowhorn seed as raw material.
Description of drawings:
Fig. 1, Fig. 2, Fig. 3, Fig. 4 are that four factors are on the impact of seed oil extraction yield.
Embodiment:
Processing step of the present invention is: after the broken shell of Wood of Shinyleaf Yellowhorn seed, get kernel and after 80 ℃ of oven dry, be ground into the powder that particle diameter is 0.5～5mm, filter, then take sherwood oil in thermostat water bath the extracting of solid-liquid ratio as 1: 5～1: 9, extracting temperature is 70～90 ℃, extraction time is 4～12h, reclaims solvent with Rotary Evaporators after the extracting.
Embodiment 1: extracting temperature is 80 ℃, and solid-liquid ratio is 1: 5, and extraction time is 6h, and planting the benevolence particle diameter is 5mm.
Embodiment 2: extracting temperature is 80 ℃, and solid-liquid ratio is 1: 7, and extraction time is 8h, and planting the benevolence particle diameter is 2mm.
Embodiment 3: extracting temperature is 95 ℃, and solid-liquid ratio is 1: 9, and extraction time is 10h, and planting the benevolence particle diameter is 1mm.
Selective extraction kind benevolence particle diameter of the present invention, extraction temperature, solid-liquid ratio, extraction time, conduct affect the influence factor of seed oil extraction yield, and they are on the visible Fig. 1 of the impact of extraction yield, Fig. 2, Fig. 3, Fig. 4.
As seen from Figure 1, in particle diameter 0.5～5mm scope, extraction yield reduces and increases with particle diameter.This is that particle diameter is less because generally speaking, and oil extraction is easier, but considers that particle diameter is too little, can increase the difficulty of broken and subsequent disposal, increases loss amount, and therefore selecting particle diameter is 2mm.
As seen from Figure 2, between 70～90 ℃, along with the raising of temperature, extraction rate increases very fast, and oil extracting rate also has certain increase.But when temperature surpassed 85 ℃, oil extracting rate tended towards stability.This is owing to originally extract the raising of temperature, can increase the kinetic energy of Lip river agent molecule and grease molecule, has accelerated molecular motion, has promoted diffusion, so the raising of temperature can increase extraction rate, makes oil extracting rate that to a certain degree increase also be arranged.But when temperature during near the boiling point of banyan agent, because the vaporization of solvent can reduce the effective contact area between the solid-liquid, oil extracting rate is descended, oil extracting rate is difficult to further raising, and when extraction rate was too fast, the solvent evaporates amount increased, and the rate of recovery descends thereupon.Therefore, 85 ℃ of preferred temperature for extraction Wood of Shinyleaf Yellowhorn seed kernel oil.
As seen from Figure 3, along with reducing of solid-liquid ratio, the increase of namely banyan agent consumption, oil extracting rate is significantly improved when beginning.This is because for the Wood of Shinyleaf Yellowhorn kind benevolence of certain mass, and the increase of solvent load can reduce the concentration of shinyleaf yellowhorn oil in the solvent, has increased the concentration difference of planting benevolence and solvent contact interface place, thereby has improved rate of mass transfer, within a certain period of time oil extracting rate increase.After solvent load increases to a certain degree, because the oily major part in the Wood of Shinyleaf Yellowhorn kind benevolence is extracted, increase again solvent load, oil extracting rate remains unchanged substantially.Therefore, optimum solid-liquid ratio is 1: 70.
As seen from Figure 4, oil extracting rate increases along with the prolongation of extraction time during beginning, but after the time reaches about 10h, extracts section and reach balance, and oil extracting rate increases not obvious, and therefore, the more suitable time is 10h.
