Description

Subcritical continuous extraction desolventizing equipment

Technical field

This utility model is related to extraction equipment, more particularly to subcritical continuous extraction desolventizing equipment.

Background technology

In recent years, subcritical abstraction technology has obtained very big development, and initially this technology is mainly used in Vegetable oil lipoprotein Extraction.With the development of this technology, current subcritical abstraction technology main application fields have:1st, with Semen sojae atricolor, Semen arachidis hypogaeae, The vegetable oil extraction field for representative such as Semen Juglandiss, Fructus Tritici aestivi, Semen Vitis viniferae, Semen Armeniacae Amarum, seed of Flos Moutan, Semen Lini;2nd, with Folium Tagetis Erectae Flavin, capsicum red pigment are that the plant pigment of representative extracts field;3rd, with Flos Rosae Rugosae, ten Herba Coriandris, Lignum Aquilariae Resinatum, Lignum Santali Albi, Fructus Foeniculi, Bulbus Allii etc. Plants essential oil to represent extracts field;4th, Ganoderma spore oil, microbial oil extract field;5th, Nicotiana tabacum L. extracts nicotine and tar Precursor field;6th, raw wool removing lanoline field;7th, the removing pesticide residues neck with Folium Camelliae sinensis, Nicotiana tabacum L., Chinese herbal medicine as representative Domain;8th, the Chinese herbal medicine effective ingredientses with Fructus Schisandrae Chinensis, Semen Cucurbitae, Folium Artemisiae Argyi etc. as representative extract field;9th, with tenebrio molitor, Pupa bombycises as generation The removing of the insecticide lipoids of table;10th, removing of fish and shrimp lubricant component with Acipenser Sinensis, squid as representative etc..Under normal circumstances, Subcritical solvent has propane, butane, iso-butane, dimethyl ether, R134a(HFA 134a)With liquefied ammonia etc..

Higher than solvent boiling point temperature but less than the temperature range of solvent critical temperature, it is defined as the subcritical shape of solvent State, this is also the liquefaction of solvent gas, material is extracted with the solvent of this state, is referred to as subcritical abstraction.Specially Profit number is the prior art of ZL90108660.6, discloses one kind《Technology for extraction of grease from liquefied petroleum gas》, belong to earliest Asia Critical extraction patent.As subcritical abstraction solvent has certain pressure, the extracting pressure of such as butane extractor is usually 5 The extraction equipment that solid material under atmospheric environment continuously loads high-pressure work is had certain difficulty by individual atmospheric pressure, so, The subcritical abstraction Processes and apparatus of current practical application in the industry, is all the batch process of pot group type, is by material After loading open extractor, closing charging aperture, then squeeze into solvent carries out subcritical abstraction, and molten in material removing in tank After agent, could discharge when pressure reaches below 0MPa.The tank group of one group of 6 tank will install more than 70 valve, operate very complicated, pole Easily maloperation, yield is little, production is unstable.In order to realize the serialization of subcritical abstraction, application number 201310197516.5《One Plant continuous dipping leaching grease equipment and technique》Disclose a kind of subcritical continuous extration method, the method two-stage feeding cylinder Material is continuously added to into infusion chamber, feed operation is loaded down with trivial details;Infusion chamber and the structure of chain-bucket infuser UNICOM, it is impossible to realize higher Miscella concentration, reduce the utilization rate of extractant;Wet dregs of rice storage tank and dregs of rice decompression precipitation tank and dregs of rice vacuum desolvation tank it Between to block pressure differential between three tanks with airlock really difficult to realize, still do not have at present to block 0.2MPa pressure reduction Airlock, also propane solvent reaches 0.9MPa with vacuum pressure reduction, in addition, in material, solvent evaporation needs are a large amount of absorb heat, dregs of rice decompression Precipitation tank and dregs of rice vacuum desolvation tank all do not design heat supply establishment, and the final finished product dregs of rice can be with very low temperature and very high Containing molten discharge.Application number 201320359608.4《Subcritical fluids continuous extraction apparatus》In disclosed scheme, material is from air Space has used two-stage rotatory sealing inlet valve, but the material between two-stage into the extractor that pressure is more than 5 atmospheric pressure In have the gaseous mixture of solvent gas that the air that upper valve brings into brought into lower valve, gaseous mixture Jing vacuum pumps enter system, in the same manner, two-stage Rotatory sealing continuous discharge valve can also bring large quantity of air into, can gather air in system quickly, and system pressure rises quickly, and arranges Have a large amount of solvent gas again to discharge when going out air in system together, not only dangerous but also waste solvent;Extractor reality in scheme It is that a kind of vegetable oil materials such as Semen sojae atricolor leach conventional crawler type infuser structure, but subcritical abstraction is completed under stress, This caterpillar belt structure to be used the shell of pressure vessel just to seem the unreasonable of device structure;One-level desolventizing device and two grades of desolventizing devices Continuous desolventizing method, make the pressure differential of two desolventizing devices very big, it is difficult to ensure that the vacuum of two grades of desolventizing devices, and it is also difficult to ensure Go out the dregs of rice dissolvent residual it is qualified.Application number 201510853263.1《A kind of low temperature subcritical fluid extraction device》Disclosed skill In art scheme, the subcritical high pressure solvent leakage of the feed auger blocking extractor of material plug closure is taken, and this structure is wayward Charging, material setier pine have escape, and subcritical solvent is inflammable and explosive liquefied gas, it is necessary to assure sealing safety, no There can be any hidden danger, this is that this structure is difficult to accomplish;Material setier is tightly readily formed smooth bore, makes spiral together with material in cylinder Middle rotation, material do not readvance, and in actual production, the Character change of material is very big, and this material plug sealing structure is it is difficult to ensure that steady Fixed production;Extractor in the program is excessively simple, and after material continuously enters extractor, not up to effect of extracting is lowered by To discharging opening, the concentration of extract also can be too low, it is impossible to realizes counter-current extraction, and solvent utilization rate is low;In the precipitation tank of the program Contain molten material continuously into high, in tank, can persistently there are elevated pressures, solvent strength can be very big, discharges the extraction slag of precipitation tank It is difficult to purify solvent, has not only wasted solvent but also produced very big potential safety hazard.
