Description

The method and the centrifugal separator that separate the apple seed in the cider process

One. technical field: the present invention relates to the separation method and the equipment of fruit seed in a kind of fruit process, particularly relate to a kind of method and centrifugal separator that in the cider process, separates the apple seed.

Two. background technology: China is apple cultivation big country, and annual apple production accounts for more than 60% of the whole world, and the apple resource is very abundant, ton surplus the only annual apple that is used for cider processing just has 4,500,000, in Jia Gong the apple, contain the apple seed of 0.125% weight approximately in this section, the apple seed is a kind of very important raw material of industry, can press into essential oil, help firm fat first, activate the active component in the fat, shine cell viability, makeup energy is alleviated skin fatigue.The apple seed also has a wonderful effect for anti-aging, and the sisleya of sisley has extremely strong palingenesis, and main component is extract edeline-L in the apple seed.The outstanding effect of apple seed progressively is familiar with by people, has many companies the apple seed to be applied on bio-pharmaceuticals, cosmetics and the health products market demand is widely arranged abroad.

The purchasing price of present domestic apple seed is at 1200～2000 dollars/ton, and the present domestic apple seed technology of in the process of cider, not separating, most apple seeds enter the feed processing industry with pomace, be equivalent to annual in the cider processing industry, there is 6000 tons apple seed to be wasted, the high value utilization of apple seed is familiar with by the stakeholder of domestic fruit juice processing industry, Liu Tong a part of apple seed product is that pomace after people will squeeze the juice is by hand slowly eluriated in water and separates in the market, labour intensity is big, effect is low, water consumption is big, the rotten also contaminated environment of waste water, influence environmentally-friendly sanitary, therefore, be badly in need of a kind of method and centrifugal separator that in the cider process, separates the apple seed and come out.

Three. summary of the invention:

The objective of the invention is: change the manual at present present situation of separating apple seed method of eluriating, relevant device is transformed, be implemented in the method and the centrifugal separator that separate the apple seed in the cider process.

Technical scheme of the present invention is:

The method of separating the apple seed in a kind of cider process, in the cider process, with the granularity of fragmentation is in the apple pulp introducing centrifugal separator of 2～5mm, isolate 85～95% pulp, wet mixture with remaining pericarp, apple seed and a small amount of pulp, or after wet mixture adds a certain amount of water, introduce the mechanical dehydration device and take off juice and dehydration, the pericarp that to be extracted, apple seed and a small amount of pulp mixture are introduced in the proportion seperator then, under vibratory sieve and certain wind speed effect, isolate the mixture of apple seed and a small amount of pulp and pericarp.

The method of separating the apple seed in a kind of cider process, in the cider process, the pomace after the belt press squeezing for the first time, after adding a certain amount of water, introduce in the centrifugal separator and isolate 85～95% pulp, remaining pericarp, apple seed and a small amount of pulp are introduced the mechanical dehydration device and are taken off juice and dehydration, the a small amount of pericarp that to be extracted, pulp and apple seed mixture are introduced in the proportion seperator then, under vibratory sieve and certain wind speed effect, isolate the mixture of apple seed and a small amount of pulp and pericarp.

The method of separating the apple seed in a kind of cider process, with the industrial waste pomace after the cider processing, introduce in the first-stage centrifugal seperator and isolate 70%～80% pulp, remaining 20%～30% pulp, pericarp and apple seed add a certain amount of water again, introduce in the secondary centrifugal separator and isolate 20%～30% pulp, remaining pericarp and apple seed enter the mechanical dehydration device and take off juice and dehydration, the pericarp that to be extracted and apple seed mixture are introduced in the proportion seperator then, under vibratory sieve and certain wind speed effect, realize separating of pericarp and apple seed.

The aperture of centrifugal separator sieve aperture is Φ 4mm～Φ 5mm, pitch-row is 6～9mm, evenly arrange, the rotating speed of screen cloth is 10～20 rev/mins, the mechanical dehydration device is a fruits and vegetables mechanical dehydration device, or be the horizontal spiral squeezer, or be oil press, or be the vertical helical pressing device, work as pericarp, after a small amount of pulp and apple seed mixture enter the pressing mechanism of screw press device or oil press, fruit juice and moisture constantly flow out from the hole of extrusion chamber or crushing chamber or seam, between the spiral wheel blade of auger, scraping mechanism is housed, constantly material is scraped to bottom from the top of squeezing cavity, assurance press dewatering process is normally carried out, the mixed material that to be extracted is introduced in the proportion seperator, under the first road vibratory sieve effect, sieve aperture is Φ 5.5mm～Φ 6.5mm, the bulky grain material is separated from the top discharge mouth of proportion seperator, remaining mixed material falls into the second road vibratory sieve equably, the second road vibratory sieve is the cloth screen cloth, two ends do not have mesh, the sieve aperture at center is 6 * 8mm or 8 * 10mm, guarantee that apple seed and apple skin in the material can fall into the 3rd road vibratory sieve by sieve aperture, the 3rd road vibratory sieve is the stainless steel material, the aperture is less than Φ 1mm, good permeability, pericarp that proportion is lighter and pulp move down under the effect of vibratory sieve and certain wind speed, flow out from lower discharge port, the apple seed that proportion is bigger constantly moves up on the inclined plane of vibratory sieve effect lower edge sieve nest, therefrom discharging opening flows out, inwall at middle discharging opening is mounted with a suspended wall deep bead, to guarantee the constantly therefrom discharging opening outflow of apple seed.

The ratio of wet mixture weight and water, or the ratio of pomace weight and water for the first time all are 1: 0.8～1.2, and the pomace of separating from the first-stage centrifugal seperator and the weight ratio of water also are 1: 0.8～1.2.

A kind of and the above-mentioned matching used centrifugal separator of method that separates the apple seed, the centrifugation cavity that contains closed at both ends, the rotating shaft of slurrying percussion device is fixed in the centrifugation cavity two end plates by bearing and axle sleeve, outside the slurrying percussion device, be mounted with filter screen, one end plate spout place is mounted with feeder at cavity, cavity bottom is provided with grout outlet, be communicated with by in through hole or groove and the cavity, the centrifugation cavity is fixed on the support, main power machines is connected by the rotating shaft of transmission mechanism with the slurrying percussion device, on another end plate top of centrifugation cavity engine is installed and is connected with filter screen with the transmission speed reducer structure, screen cloth and slurrying percussion device relatively rotate.
