Description
The present invention relates to fresh coffee beans processing method and dejacketer.
In the past, the operation of curing of coffee bean was generally carried out in enormous quantities by the operator, and then the coffee bean that will cure is sold individual consumer or other people.In this case, use day often will pass through some fates from curing day to reality taking-up coffee liquid, so exist the problem that the coffee liquid taste is partly lost.
Therefore, such tendency is arranged recently, promptly make the state before coffee bean keeps curing as much as possible, before the moment of taking out coffee liquid, just cure.
In being called the device of automatic coffee making machine, owing to be before the moment of taking out coffee liquid, just coffee bean to be cured, so, must preserve without the coffee bean that cures.
Yet, the coffee bean that does not cure is used as commodity or for actual, must remove the foreign material (things beyond the beans) of sneaking into, and the skin of coffee bean is sloughed.
The skin of above-mentioned coffee bean, its innermost layer skin is called parchment covering, and giving elder generation's this parchment covering of removal has two benefits, and the one, saved the trouble of removing the parchment covering under when curing, separating, the 2nd, can reduce undesirable constituents such as astringent taste that coffee takes out liquid, peculiar smell, can obtain espresso liquid.
Remove the method for above-mentioned parchment covering, can roughly be divided into two operations, the one, from the band parchment covering fresh coffee beans of import, the operation of the foreign material that removal is sneaked into (thing beyond the coffee bean), dust, dirt, another operation are to remove the operation of parchment covering after removing foreign material from the beans of band parchment covering.
In the past, in the operation of removing foreign material, often adopt the measure of washing and heat drying; Or the operation of desilverization skin from the beans of band parchment covering, make water, or in the operation of removing parchment covering, also make water.
Coffee bean dejacketer in the past is to having removed the band parchment covering coffee bean of foreign material, removes parchment covering on the beans with friction mode, has adopted the form that resembles the fine finishining rice device.
But the inventor finds that when handling the fresh coffee beans of band parchment covering, in case used water, if do not make it dry rapidly, then coffee bean can absorb water and expand, and causes and can not use.So,, make it dry rapidly in the past all to the beans heating.But, heated after the beans, even it does not have blackening, organizing of beans is also downright bad, no longer is to give birth to beans, the tissue of beans, one-tenth grade can be very fast in time rotten, and no longer can preserve coffee bean with " life " such kilter.Its result can not get the coffee liquid of aromatic flavour.
In addition, coffee bean has various kind as preference, must strictly separate by kind, but in above-mentioned coffee bean dejacketer in the past, when wanting conversion coffee bean kind time-like, can not remove the processed beans that remain in the device quickly and easily, and these beans and the new another kind of beans that drop into are mixed.
The present invention proposes for the shortcoming that overcomes in the above-mentioned conventional art, and its purpose is to provide a kind of fresh coffee beans processing method that can make the fresh coffee beans of being with parchment covering still can keep " giving birth to beans " state after sloughing parchment covering.
Another object of the present invention provides the kind time-like of beans that a kind of conversion in processing procedure is handled, and can remove residual processed beans rapidly, newly drops into the fresh coffee beans dejacketer that beans are handled.
For achieving the above object, the feature of fresh coffee beans processing method of the present invention is the living beans that his-and-hers watches are worn the parchment covering state, does not wash with water and heat drying, and removes foreign material with the dry-type separation method, then, carries out some times grinding step repeatedly, does not remove parchment covering with not adding water.
Fresh coffee beans dejacketer of the present invention has at least: the hopper portion that the surface is fallen input with the living beans of parchment covering, the band parchment covering that falls input is given birth to the spiral that beans push forward transports portion, with spiral transport portion the coaxial rotation of feed spiral abrasive roller and constitute the mesh tube that grinds the gap in the whole periphery of this abrasive roller; Beans when mobile, ground and are removed parchment covering in grinding the space, behind the grinding space, are discharged to the outside from the outlet that is located at the pre-position; It also is provided with the compressed air blowoff, and the foot space that this air blowoff can transport portion from the above-mentioned spiral of hopper subordinate side is jet to outlet through grinding the space.
According to fresh coffee beans processing method of the present invention, can give birth to the beans from the band parchment covering that is mixed with foreign material, remove foreign material and further remove the coffee bean that parchment covering is processed into no skin,, can not produce because of absorbing the adverse consequences that moisture causes owing to do not make water in this course.And, owing to do not make water, also just need not carry out heat drying, thereby can make beans maintain " giving birth to beans " state.Therefore can prevent rotten (by long-term maintenance, become old coffee powder, taste is better) of beans for a long time, can carry out the meticulous coffee liquid of curing and take out at any time.
In the manufacture method of the present invention, owing to, be to carry out some times grinding step repeatedly, so can not add water for removing parchment covering, do not make the beans breakage, and grind bit by bit, remove parchment covering at last fully, and beans to grind the amount of cutting few, thereby less wastage, yield rate height.The no skin in bean or pea surface that is processed into is smooth, very clean.
