Vacuum extractor of the present invention is mainly led threeway 29 etc. by vavuum pump 30, vacuum tube and is formed.Vavuum pump 30 is connected with distillate collection tank body 25, the amount of heating up in a steamer watch-dog canister body 20 respectively by threeway on the pipeline 29, guarantees that negative pressure equates in two tank bodies, and it is free dirty unimpeded to keep distillate.
Operation principle of the present invention:
The present invention is placed on spices such as ginger, green onion, garlic, capsicum in the shelf 5, and shelf 5 are placed on the rotary-tray 4, and rotary-tray 4 adopts the little material of high frequency dielectric losses such as four fluorine ethylenes, polypropylene to make with shelf 5.Cover negative-pressure sealing storehouse lid 2, utilize the lid deadweight, compress silicone rubber O-ring 3, close vent valve 14, close bleeder valve 28 simultaneously, start vavuum pump 30, total system is vacuumized, when vacuum meter 13 pointers arrive setting value (general setting value for-0.09Mpa), open microwave power generator 7, in the negative-pressure sealing storehouse, launch HIGH-POWERED MICROWAVES, material heats up on the shelf 5, and the discharge steam, steam has also comprised the volatile essential oil steam based on steam.Steam by vavuum pump 30 aspirates through condenser coil 15, forms condensate liquid at the coil pipe inwall, flows into downwards within the amount of the heating up in a steamer watch-dog canister body 20.Coil pipe is outward a low-temperature cooling water 17.Water temperature is low more, and distilling effect is good more, generally controls water temperature: the 3-5 degree.With water supply pump and cooling water refrigeration, recycle.
Regulate the critical adjustable valve 24 that heats up in a steamer, set the critical amount of heating up in a steamer.When material water ratio was higher, distillate was to the influx of canister body 20 discharge greater than valve 24, made that liquid level rises in the monitoring canister, overflow when putting the mouth of pipe of pipe 23 when rising to, and put pipe 23 through overflowing and flowed into distillate collecting tanks 25.When the approaching drying of material, distillate reduces, and the influx of the amount of heating up in a steamer watch-dog canister body 20 is less than the discharge of valve 24, and liquid level descends, and the dress monitoring and controlling liquid level of flux pops one's head in 21 in the amount of heating up in a steamer watch-dog.The suitable switch of popping one's head in tank skin.When liquid level surpasses probe, make switch logical by water, when liquid level is lower than probe, be equivalent to switch and break.This switching signal by control signal output line 22, goes control to close microwave power generator 7.Material utilizes waste heat, and after continuing dry several minutes under vacuum condition, material is all dry.Close vavuum pump 30, open vent valve 14, the deactivation system vacuum is opened seal cover 2, takes out dry material.Open bleeder valve 28, obtain distillate.Distillate is injected in the large-scale storage tank that is provided with in addition, stored for several days, profit separates automatically, and oil is frivolous last, and water focuses on down.Oil water surface is clear, gets oil on interface, discharges water under interface, and this is the water-oil separating method of most economical practicality.Water-oil separating can also be used from the core method and separate, and will note airtight, low temperature when oil-water mixture stores, and prevents from or reduce essential oil to volatilize.
Distillate 26 can be observed by distillation liquid level observation window 27, can see distillation liquid level height.Account in addition and can also penetrate the function situation of shrinking when viewing glass 10 is watched dry materials in the gas-tight silo by the anti-width of cloth on the negative-pressure sealing storehouse.
By above-mentioned rationale, solid material can not volatile component, under the condition of low temperature non-oxidation, taken off moisture content fast, can not can be retained in good condition in the dried base material by volatile component.Obtain volatile essential oil in addition, dumped moisture content.If base material is worn into powder, and essential oil is distributed in the base material in proportion, can obtains powdery flavouring such as full price ginger, green onion, garlic, capsicum, its quality excellent can surpass the like product that other any methods are at present produced.Become the elaboration of outshining othersOne branch of the tree is particularly thriving.Particularly garlic not only can keep original fragrant pungent in good condition, and can take off the stink of garlic.Because stink is a sulfur-containing compound, the part sulfur-containing compound is difficult for being reverse into liquid, can be aspirated venting by vavuum pump.The part water soluble be reduced into solution with the water distillation, but essential oil is water insoluble, has further separated sulfur-containing compound during water-oil separating again, so can obtain odorless full price garlic seasoning elaboration.
The present invention is under vacuum condition, and moisture content gasification boiling temperature is: 40 degree.Volatile essential oil in the spices such as ginger, green onion, garlic, capsicum, the gasification boiling temperature is more much lower than moisture content, and therefore in the vacuum microwave system, when dehydrating under the cryogenic conditions, volatile essential oil also gasification is simultaneously volatilized in steam.Form condensate liquid when these steams, when the condenser coil, be distilled into the oil-water mixture body, pass through conventional water-oil separating again after, extract essential oil.Can obtain simultaneously the dewatering drying product of spices such as ginger, green onion, garlic.Spice is microwave distillation under vacuum condition, there is not oxidation, temperature is low, the time is short, when not decomposition, sex change, the present invention have overcome boiling way of distillation extraction essential oil, destroyed the thermal sensitivity composition, overcome being decomposed of in high temperature, having, what have is oxidized, and sex change is spoiled, and also some protein, carbohydrate, compound also have been overcome by the problem of the assorted gas of pyrolytic generation.
For garlic, garlicky delicate fragrance, pungent be the seasoning good merchantable brand.But after the food, stink is offensive, and the main cause that produces stink is that the sulfur-containing compound in the garlic is abundant, and sulfur-containing compound is easy to gasification with water evaporates, and the part sulfur-containing compound is to be difficult for condensation to be reduced into liquid, is taken off by the vavuum pump suction and has arranged.The also reducible one-tenth of part sulfur-containing compound is liquid, but it is water-soluble, and essential oil is water insoluble, and distilled water accounts for more than 97%, and essential oil only accounts for about 2%.Further got rid of sulfur-containing compound during water-oil separating again.So with the big garlic spice of full price that the present invention produces, sloughed the stink of garlic, kept the elite of garlic in good condition.Can be made into senior odorless, easily preserve, refining garlic products easy to use.
