Embodiment
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with specific embodiment, the present invention is described in further detail.
Below in conjunction with embodiment, the specific embodiment of the present invention is further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
A production method for lemon quintessence oil, its concrete steps are as follows:
Select raw material fruit: the lemon fresh fruit selecting 7-8 maturation, lemon plucks the time 24-48 hour to delivering to source mill and carrying out processing from tree, remove rot to go mouldy, disease and pest really, Lemon fruit transverse diameter requirement >=40mm.
Pressure pulse cleaning: former fruit carries out bubbling flushing in Xi Guochi, remove silt and the foreign material of its surface attachment, Xi Guo pond, underground length, width and height are of a size of 3mx2mx3m, wash fruit pond median water level and remain on 3/4ths high places of pond, the thickness of lemon in Chi Guochi keeps 20 centimetres high, add before lemon and open surfing water pump, allow water rolling in pond.
Cleaning showers is sterilized: Lemon fruit in fruit pond is sent into ozone pond by the board-like lift with three sections of sprays, synchronous spray irrigation removes fruit telogenesis sewage, spray hydraulic pressure keeps 0.2-0.3MPa, water surface distance 40-60cm in lift outlet distance tank, consistency of ozone water 2-3mg/L, PH:5.0-5.5,2-3 minute during ozone water process, reduce fruit face heavy metal and agriculture residual, and by rolling bar lift send into grading machine.
Size classification process: carry out classification by three kinds of specifications, be respectively the fruitlet of 40-50mm, the middle fruit of 50-65mm, be greater than the large fruit of 65mm, wherein fruitlet enters the little oil grinding machine of a passage, and middle fruit enters oil grinding machine in the second to the 7th passage, and the fruit of large fruit 65mm enters the and enters the large oil grinding machine of eight passages.
Wipe skin centrifuging and taking oil: enter by the fruitlet of size classifier, middle fruit, large fruit lemon the oil grinding machine that diameter is 800mm, 1000mm, 1200mm respectively, grind oily controling parameters: every each inlet amount 50-60 kilogram of platform, spray water flow 1.2-1.5 ton/hour, hydraulic pressure keeps 0.5-0.6MPa, and spray water recycles; Fruitlet mill fruit machine revolution 100-140 rev/min, mill oil time 60-65 second, middle fruit mill fruit machine rotating speed 140-160 rev/min, mill oil time 65-70 second, large fruit mill fruit machine rotating speed 160-200 rev/min, mill oil time 70-75 second.Due to the twirl of mill, Lemon fruit is constantly rolled on mill, simultaneously, due to the effect of centrifugal force, Lemon fruit also constantly collides with surrounding machine wall, Lemon fruit epidermis is clashed into by the mill that rotates that pericarp oil vacuole is fully ruptured is broken fuel-displaced, and essential oil punching to oil grinding machine bottom recovery unit is formed oil-water emulsion by HP shower and enter next process and filter, and puies forward the Lemon fruit external form after oil complete.
Refinement treatment: first filtered by vibratory screening apparatus from oil grinding machine oil-water residue mixture out and remove thick slag, mesh size 200 order, amplitude 5-9mm, the dregs of fat of gained carry out refinement treatment through spiral finishing machine, contained oil grain slag in pomace is separated further, and after twice initial filter, the oil-water residue mixture of gained carries out oil refining by being pumped into butterfly separating machine.
Butterfly centrifugal is refined: when lemon oil grain slag mixture flows through the gap between video disc, solid particulate is deposited on video disc and forms sediment under whizzer effect.Sediment slides along disc surface and departs from video disc and accumulate in the maximum position of rotary drum interior diameter, because lemon oil proportion is lighter than water, in whizzer high-speed rotation, under centrifugal action, be collected at upper strata flow out from light liquid relief outlet, the water after separation enters cyclic water tank from the discharge of bottom heavy-fluid and makes spray water by being pumped into oil grinding machine.Butterfly separating machine rotating speed 7000 revs/min, profit feed rate control 1.2-1.5 ton/hour.
Low temperature stores sedimentation in advance: by the moisture content of lemon oil also containing minute quantity of butterfly separating machine gained, lemon oil can be made to produce producing microbial ruin and be oxidized, lemon oil sealing is temporary in bottom to be had in the cone-shaped stainless steel bucket of discharge outlet, in the storehouse of 0-10 DEG C, leave standstill 48 hours, discharge a small amount of moisture and micro-slag that are deposited on bottom.
Temperature control stores: be sub-packed in 100 liters of stainless steel casks by the sealing of the lemon oil of gained, store in the storehouse of 0-10 DEG C.Product uncap use before need to move to outdoor exercise use again after temperature return to room temperature, prevent the moisture in air from meeting and coldly condense in lemon oil surface.Packaging vessel can not use metal bucket and plastic tank, Liquid level bung 2-3cm place, avoids the oxygen in bucket in residual air to cause oil oxidation.
Get compared with oil process with horizontal oil grinding machine with cup type squeezing the juice, the extraction yield of vertical mill oil machine of the present invention is the highest, because first carried out Lemon fruit classification before mill oil, according to the oil grinding machine that Lemon fruit transverse diameter selects diameter different, be that the quartz sand of 3mm makes the equipment surface contacted with lemon be uneven by all scribbling diameter at rotating grinding board wall and machine surrounding inwall, due to the twirl of mill, Lemon fruit is constantly rolled on mill, simultaneously, due to the effect of centrifugal force, Lemon fruit also constantly collides with surrounding machine wall, operation scheme is irregular operation shape, include rolling, collision, the modes such as friction, achieve comprehensive without dead angle mill oil, Lemon fruit epidermis is clashed into by the mill that rotates and inwall that pericarp oil vacuole is fully ruptured is broken fuel-displaced, and extracted under the top-down flushing of HP shower, enter next process in oil-water residue mixture to filter.Mill fruit time arrival trailing flank door is automatically knocked at the door and is opened, and the lemon after mill oil throws away at the reactive force of mill centrifugal force and enters lower step operation.Grind speed of grinding plate and mill oil time in oily process simultaneously and all can do corresponding adjustment according to the characteristic of lemon fresh fruit.Its another principal feature is that single short run is concentrated and got oil (unit single enters lemon 40-60 kilogram), and simultaneously quartz sand quality is hard, wear-resisting acidproof, can not by lemon acid damage.
Horizontal oil grinding machine is (as Wuxi section peace, Jiangsu section prestige etc.) be by installing friction plane or screw rod in casing additional, rubbing in plane or screw rod is arranging jagged thorniness metal strip or draw point formation friction plane, friction integral plane is undertaken rhythmically rocking and vibrating or under the propelling of screw rod by the device that mounting spring device principal oscillation motor forms similar shaking table, Lemon fruit is in upper surface jitter and rolling, the oil vacuole of exocarp is punctured by draw point and gets oil, it is one of foot point not: due to lemon fruit be in the middle part of ellipse circular large two little, it is beated and concentrates on middle part with the primary friction face in roll procedure and cause the oil vacuole at lemon two ends place to be not easily punctured, not foot point two: because thick and comparatively hard and by lemon the peracidity of lemonade pericarp affects, the draw point easy passivation of needle point in use for some time, lemon oil vacuole is caused to puncture not thorough, not foot point three: Lemon fruit is in the oily process of mill, lemon leans on the promotion naturally of rocking of grinding machine or screw rod to move ahead, and adopt and enter fruit continuously, the mode of mill oil, the fruit after the fruit that newly enters and mill is easily made to mix, there is the phenomenon that part fruit excessively grinds oil and part fruit mill shortage of oil, because lemon is continuous advance, grinding machine length is fixing, then lemon mill fruit residence time in a device and the fltting speed of shaking table or screw rod are inverse relation, corresponding adjustment can not be done according to the size of Lemon fruit and fresh new degree, thus cause lemon oil extraction yield not enough, slow down speed, although the mill fruit time lengthens, but grind oily intensity to reduce, the not broken oil vacuole of thorn, tune up speed, though intensity increases, the mill oil time reduces, and does not reach the object of fully mill fruit.
Another kind is cup type (bowl formula) juice extractor (as U.S. JBT, poplar state Fu Er like), this machine is lemon is got to oil, squeezes the juice, the lower cup of single lemon access arrangement one by one, and oil obtains when being cup and lower cutter under fruit is placed, upper cup is anti-to come, and after extruding, fruit juice enters recycling machine.Meanwhile, pericarp shreds, and passes through at upper strata cup, and oil vacuole fracture is fuel-displaced.Though achieve get oil, squeeze the juice synchronously carry out and be separated, but its central principle of getting oily mode still extrudes, the middle part mainly concentrating on fruit of main stress point, the oil vacuole at base of fruit two ends place is not easily extruded to, from causing, oily extraction yield is on the low side, simultaneously because the cup size of every platform machine is fixing, lemon can only carry out classification by relative dimension scope, and therefore lemon can not coordinate completely with the size of cup and affect squeezing effect; In addition due to through cup type squeezing machine out after lemon peel shredded, the following process form of skin is single, after drying, obtained lemon peel slag is sold, and the lemon external form after this law processing remains unchanged substantially, except squeezing skin slag processed, also can be processed into the goods such as carbohydrate freeze-dried lemon slices, fruit fourth, following process utilizes channel more wide.
Below be only the preferred embodiment of the present invention, it should be pointed out that above-mentioned preferred implementation should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with claim limited range.For those skilled in the art, without departing from the spirit and scope of the present invention, some improvements and modifications can also be made and also should be considered as protection scope of the present invention.
