Abstract
The invention discloses a method of extracting castor oil from castor seed meal, belonging to technology field of producing fatty oil out of raw materials. Cold processed castor seed meal and industrial alcohol are mixed together according to a proportion of 1:1 to 1:5 and are disposed in a recycling extraction tank, extracting for 30 to 120 minutes at a temperature of 90 to 110 DEG; then filtering with a roller filter; the mixed oil is proceeded by vacuum removing and dissolving to obtain the extracted castor oil; the wet castor seed meal can be made as fertilizer or used for further manufacture after the solvent is separated through evaporation; The solvent is rectified through a rectifying tower and recycled into the solvent tanker for recycle use. Comparing with the prior art, the invention has advantages of high efficiency, low residual oil content and good effect.
Description
(1) technical field:
The present invention relates to the extraction of Viscotrol C, particularly use the method for ethanol lixiviate Viscotrol C.
(2) background technology:
Castor-oil plant (Ricinuscommunis) is for being the annual or per nnial herb of Euphorbiaceae (EuphoribiaL), barren-resistant, adaptability is strong, cultivation management is convenient, farming is comparatively extensive, comprehensive utilization value is high, the industry chain length, it is the gentle time of region-by-region not, anti-necessarily saline and alkaline, few disease and pest, resistance is very strong, and well developed root system helps soil conservation.Castor seeds oil length height, its contained Viscotrol C is unique natural acid that contains hydroxyl, has special physico-chemical property, and is of many uses.Because plantation castor-oil plant has purposes and higher economic value widely; in national economy, occupy an important position; particularly oil faces to consume and treats most crisis in the world today; as the castor-oil plant of plant-sourced oil plant because it has the advantage of Sustainable Production and the important value that can not be substituted; be subjected to the attention of countries in the world just day by day, its industrial prospect is boundless.
Existing Viscotrol C processing technology mainly contains two kinds: mechanical expression method and solvent extraction method.Mechanical expression method method commonly used has cold press (hydraulic pressure milling process) and hot moulding method (screw press method), all has the high problem of oil cake residual oil content.
Industrial commonly used be the solvent extraction method, be with castor seeds select seed, strip plate, steaming fry, press in advance and solvent extraction after, through refining and processed oil.The solvent extraction method has characteristics such as cost is low, Residual oil is few, oil yield height.At present, the most frequently used solvent is a normal hexane in the grease leaching process.
Normal hexane can dissolve grease with any ratio, and is also smaller to the solubleness of water, and has volatility and chemical stability preferably, and it is atomic to contain hazardous substance, and is a kind of reasonable grease leaching agent.Hexane is as the existing semicentennial history of grease leaching agent, but the U.S. has issued the decree that purifies air (CAA) nineteen ninety, hazardous gas pollution (HAP) and volatile organic matter federal regulations such as (VOC) have been set up subsequently again, normal hexane is classified as one of 189 atmospheric pollution objectionable impuritiess, and this has caused the query of people to existing solvent practicality.Thereby, reselect new solvent, develop new technology, become one of focus of oil prodution industry technical renovation.EPA (EPA), U.S. food medicine office (FDA), USDA (USDA), U.S. oil chemistry association (AOCS) very payes attention to this.Problems such as in addition, also there are some shortcomings in solvent extraction method itself such as extraction time is long, leaching efficiency is low.Can't satisfy needs of society.
(3) summary of the invention:
1, goal of the invention: the objective of the invention is to select for use industrial alcohol as the leaching solvent, and improve extraction temperature, to shorten extraction time in order to solve the deficiency in the existing Viscotrol C production method.Provide a kind of efficient height, the production method of the Viscotrol C that residual oil content is low.
2, technical scheme: technical scheme of the present invention is: a kind of method of extracting Viscotrol C from castor seed meal, comprise the steps: the castor-oil plant dregs of rice after the cold press and industrial alcohol are put in the circulation leaching can with 1: 1～5 mixed, under 90～110 ℃ of temperature, leached 30～120 minutes; Filter through the spinning roller filter again; Mixing oil must leach the castor-oil plant crude oil through the vacuum precipitation; The wet dregs of rice of castor-oil plant can be made fertilizer or do further processing after solvent is isolated in evaporation; Solvent is recovered into solvent tanker through rectifying tower rectifying and recycles.
3, beneficial effect: the present invention is solvent with the industrial alcohol, and improves temperature, strengthens solvent ratios, can reduce extraction time significantly, reduces production costs.
(4) description of drawings:
Figure of description is a process flow sheet of the present invention
(5) embodiment:
Castor seeds through the cleaning after carry out routine select seed, shell the back cold press, most of Viscotrol C; With the castor-oil plant dregs of rice of cold press and industrial alcohol mixed, under 110 ℃ of temperature, leach with 1: 2; The partial solvent of evaporation flows into circulation leaching can internal recycle and uses after condensation; Leached 60 minutes, and filtered through the spinning roller filter; Mixing oil carries out the vacuum precipitation, must leach the castor-oil plant crude oil; The wet dregs of rice of castor-oil plant can be made fertilizer or do further processing after solvent is isolated in evaporation; Solvent is recovered into solvent tanker through rectifying tower rectifying and recycles.Circulation leaching can that the present invention is used and spinning roller filter are commercially available common equipment, and type selecting is supporting very convenient; The ethanol of lixiviate preferably both can reduce cost with industrial alcohol, also enhanced productivity because of industrial alcohol concentration Gao Erke.
Claims (6)
