Abstract
The present invention discloses a juice extracting method for preparing pineapple juice and a device. The existing pineapple juice extracting methods have the disadvantages of low juice extraction rate and low sarcocarp content because the particle diameter of pineapple sarcocarp for extracting juice is not suitable for juice extraction of the juice. Practice shows that the juice is suitably extracted and the content of the sarcocarp is suitably increased when the pineapple sarcocarp is pulverized into a sliver shape and the particle diameter of the pineapple sarcocarp is from 3 to 5MM. The present invention has the technical scheme that the pineapple sarcocarp is crushed by a crushing machine; the action of a sliver-shaped mesh screen makes the pineapple sarcocarp come out of the crushing machine, and fruit particles with the particle diameter smaller than 10MM and in a sliver shape or irregular shapes are formed; the actions of the grinding of a colloid mill and the sieving of a pulping machine make the particle diameter of the sarcocarp reach 3 to 5MM uniformly; the pineapple juice with the juice extraction rate of over 65% and the sarcocarp content of 6 to 14% is obtained after squeezing.

The invention belongs to the fruit juice production field, what be specifically related to is exactly a kind of juice extracting method for preparing pineapple fruit juice.
(2) background technology
It is poly-that the preparation of pineapple fruit juice approximately can be divided into four steps, is respectively extraction of the juice, the enzyme that goes out, concentrates and the sterilization can.Extraction of the juice is a relatively critical step, because what of the height of crushing juice rate and flesh-content have directly influenced juice quality and cost.At present, juice extracting method commonly used has two kinds, and a kind of is cold formulation, and another kind is hot formulation.The sequence of steps of cold formulation is: pineapple fruit-cleaning-meat planing machine plane meat-beater making beating-centrifugation-enter concentrated.The sequence of steps of hot formulation is: pineapple fruit-cleaning-blanching-screw rod squeeze-is added with heat-worm gear extraction of the juice-enter concentrated.The crushing juice rate of cold formulation is lower, generally is no more than 42%, and flesh-content is no more than 8%.The crushing juice rate of hot formulation is higher, but also is no more than 54%, and flesh-content is no more than 5%.The pineapple pulp particle particle diameter that the pulp surfacer that the lower reason of cold formulation crushing juice rate is to adopt in the method is dug is bigger, and usually greater than 20 millimeters, big like this pulp particle particle diameter is unfavorable for the raising of crushing juice rate and flesh-content.And the lower reason of hot formulation crushing juice rate is equally because pulp particle particle diameter problem, juice extracting method will be put in order fruit by screw press and squeeze pulp extraction of the juice again in hot formulation, with whole process of really squeezing pulp, the pulp layer is thickened, fruit juice is heavily inhaled serious, fruit juice just is difficult to carry drawn, so just caused crushing juice rate low.Facts have proved,, when particle diameter is the 3-5 millimeter, help the proposition of fruit juice most, also help most improving the content of pulp when pineapple pulp is fractured into strip.
In addition, used juice extracting method because the restriction of equipment is less to the day output of pineapple fruit, if strengthen day output, then must add the cost of investment of large equipment at present.
(3) summary of the invention
The object of the present invention is to provide a kind of juice extracting method for preparing pineapple fruit juice, crushing juice rate in the time of can improving the preparation pineapple fruit juice with the inventive method and raising flesh-content.
For achieving the above object, the present invention has taked such measure: a kind of juice extracting method for preparing pineapple fruit juice has comprised following step:
(1) clean pineapple is really dropped into fragmentation in the disintegrating machine, obtained particle diameter less than 10 millimeters the strip or the fruit grain of irregular bulk;
(2) after the fruit grain process colloid mill grinding with above-mentioned strip or irregular bulk, obtaining particle diameter is the fruit grain of 3-5 millimeter;
(3) be that the fruit grain of 3-5 millimeter drops in the beater and sieves with above-mentioned particle diameter, obtain fruit grain of uniform size, through the belt press squeezing, then can obtain the fruit juice that flesh-content is 6-14% again;
(4) above-mentioned fruit juice passes through centrifugation again, and the impurity in the fruit juice is separated, and fruit juice can enter next process;
Wherein said disintegrating machine mainly is made up of cabinet and the main shaft that is installed in the drive hammer leaf rotation in the cabinet, the 16-24 that thickness is installed is 5-12mm on the main shaft is hammer leaf, bottom at main shaft also is mounted with screen cloth, and the sieve aperture on the screen cloth is that elongate in shape, sieve aperture spacing are 8-10mm.
Take the present invention of above-mentioned measure, with crusher in crushing pineapple pulp, and the effect of the screen cloth by elongate in shape, make when pulp comes out from disintegrating machine, become elongate in shape or erose particle diameter less than 10 millimeters fruit grain, again by the grinding of colloid mill and the sieving actoion of beater, make the pulp particle particle diameter reach the 3-5 millimeter equably, press through the pulp book lamination of belt press so again with the 1-2 cm thick, because pulp layer book, fruit juice is heavily inhaled few, and fruit juice crushing juice rate height just can obtain crushing juice rate and reach more than 65% after this squeezing, flesh-content reaches the fruit juice of 6-14%.Because the operation principle of disintegrating machine is comparatively simple, and effect is highly desirable, compare with employed extraction of the juice equipment in the existing pineapple fruit juice production, handling day under the identical situation of fresh fruit amount, cost reduces greatly, existing and the pineapple really similar equipment of disintegrating machine have pulp surfacer, pressafiner, and these equipment generally all will be counted and pick up ten thousand even up to a million yuans, and disintegrating machine of the present invention to be the number of the required capital quantity of the said equipment pick up/one.Thereby behind employing the present invention, the cost of producing pineapple fruit juice can reduce significantly.
