Technical field
The present invention relates to the method that a kind of grease extracts, relate in particular to a kind of liquid dimethyl ether and extract greasy method.
Background technology
At present, can low-cost industrialization extracting greasy main method is that milling process and lixiviate are followed the example of
Above method exists following defective and deficiency:
The de-oiling efficient of milling process is low, normal residual grease more than 4% in cake, even up to 10%, loss is bigger, and required equipment is more, and product is impure many, product subsequent disposal complex procedures, and be confined to contain the material of innage.
Lixiviate is followed the example of, and extraction time is long, and efficient is low, and solvent loss is big, difficult solvent recovery, and be confined to oil cake or the less material of oil-containing.
Summary of the invention
The inventive method has overcome the deficiency of above method, provide a kind of technology simple, the extraction yield height, product is impure few, it is little to consume energy, and solvent loss is little, and required equipment is few, production cost is low, can be extensive from material seed, kind benevolence, kind shell, the greasy method of extraction through the seed oil cake that squeezing was handled under the low-cost condition.
The inventive method may further comprise the steps:
1) material is crushed to 10～40 orders;
2) adopting liquid dimethyl ether is extraction solvent, press material: in the weight ratio feeding material of solvent=1: 2～1: 24, be 5～30 kilograms at pressure, extraction temperature is under 30～90 ℃ the condition, to extract 30～120 minutes;
3) be 1～5 kilogram at pressure, temperature is under 20～60 ℃ the condition, to isolate grease.
Above-described material can be in cream paulownia, castor-oil plant, seal chinaberry, rape, the cotton any.
Above-described material can be a seed, plant benevolence, plant shell, in the seed oil cake that squeezing was handled any.
Beneficial effect of the present invention is because to have adopted the liquid dimethyl ether with strong dissolving power and diffusibility be extraction solvent, by temperature, the pressure of control extraction solvent, alternative from material seed, kind benevolence, kind shell, oil and grease extracting through the seed oil cake that squeezing was handled.Concrete beneficial effect is as follows:
1, selective extraction of the present invention is effective, comprehensive extraction yield height.
2, technology is simple, fixed capital input-output ratio height such as factory building, equipment, and the energy and solvent consumption are little, production cost is low, favourable industrialized production.
3, solvent easily gasifies when lower temperature, compressed, cooling back recycle and reuse, and slag (oil cake) can utilize fully, and production process is water not, no waste gas, waste sludge discharge, thereby environmentally safe.
4, product subsequent disposal difficulty is little, favourable in-depth processing.
