Description

A kind of method of processing naked walhut

Technical field:

The present invention relates to a kind of production method of processing walnut, particularly a kind of production method of batch machining of naked walhut.

Background technology:

" naked walhut and the processing method " of inventor's application discloses a kind of walnut fabricated product and processing method, processing method wherein has: the step of second in the specification specific implementation method among the embodiment one " is pressed into adhesive solvent in the walnut shell from the umbilical region of walnut with the mode that pin injection or Needleless injection are arranged " one by one, in the 3rd step " walnut that will inject the capacity adhesive solvent really is placed in the centrifuge and rotates; adhesive solvent is flowed evenly coat the inwall of walnut shell ", the 4th go on foot " will inject the capacity adhesive solvent and put into clear water and be dipped to the walnut kernel imbibition benevolence skin is got final product with contacting as far as possible greatly of walnut shell " through the walnut of centrifugal treating in walnut shell.

Though this processing method is simple, there are the following problems

Adhesive solvent is depressed in the walnut shell from walnut umbilical region notes, carries out one by one, bring the low problem of production efficiency.

Annotate the pressure process and be subjected to factor affecting such as adhesive solvent concentration, viscosity and walnut shell internal pore size, make enter in the walnut shell adhesive solvent whether capacity be difficult to control and determine.

The clear water immersion process may make the adhesive of original injection deficiency run off once again influences adhesive strength.

It is possible make the open texture of walnut umbilical region become chip to be brought in the walnut shell that adhesive solvent enters in the walnut shell from walnut umbilical region pressure injection, directly influences adhesive strength.

More than four kinds of factors directly influence the final effect of processing, the threshing performance of walnut kernel skin is played pendulum is difficult to control, and then influence the harmony of manufactured goods quality.

Therefore, improve above-mentioned processing method and become the necessary ways that improve the quality with efficient.

Summary of the invention:

The above-mentioned processing method that develops into of vacuum technique provides the improvement approach, the present invention is exactly a mode of background technology being injected adhesive solvent from the walnut umbilical region, changing the creation vacuum environment into utilizes atmospheric pressure adhesive solvent to be sucked and fills the gap of walnut shell inwall and walnut kernel formation from any passage on the walnut shell, any passage on this walnut shell comprises that the walnut umbilical region is not limited to the passage of the liquid permeable that the walnut umbilical region generates naturally, and one step of three step process in the background technology is finished.

The present invention realizes that the mode of such scheme is, the ready processing object of the first step among the background technology embodiment one put into take out jar in advance and vacuumize, wait to deflate reach more than 90% after, add prewired adhesive solvent that contains adhesive and other flavor enhancement and the walnut that submergence is processed, and then discharge negative pressure of vacuum to normal barometric pressure, and allow walnut " being dipped to the walnut kernel imbibition makes the benevolence skin get final product with contacting as far as possible greatly of walnut shell " in prewired adhesive solvent, this mode that one step of three step process is finished has effectively overcome the existing four kinds of defectives of background technology, making one by one, processing becomes batch machining, can ensure that the adhesive solvent pack completeness is more than 90%, save centrifugal processing, soak is changed into adhesive solvent by clear water, can make the consumption of filling adhesive solvent be convenient to measure repeated use with surplus, its chip has been taken out of when vacuumizing outside the walnut shell, has been suspended in the adhesive solvent liquid level when the submergence walnut; Owing to insert adhesive solvent and be same as immersion simultaneously, can adding flavor enhancement, that the kernel of the walnut of processing is pickled in immersion is spoiled, makes seasoning be operated in also solution in the lump in this operation.

Further specify the production method of this processing naked walhut below in conjunction with embodiment

Specific implementation method

Embodiment one:

The first step:

Rascal has been taken off in selection, the complete cleaning of shell, make the fresh walnut fruit that has produced the slit between shell and the kernel as processing object through preliminarily dried, simultaneously being equipped with water-soluble glue such as amylan etc. in advance is main solute, flavor enhancements such as edible salt sugar are that less important solute, water are solvent, and concentration is the adhesive solvent more than 2%.

Second step:

Processing object put into take out jar in advance and vacuumize, wait to deflate reach more than 90% after, add the walnut that prewired adhesive solvent and submergence are processed, and then discharge negative pressure of vacuum, and allow walnut in prewired adhesive solvent, be dipped to the walnut kernel imbibition benevolence skin is got final product with contacting as far as possible greatly of walnut shell to normal barometric pressure.

The 3rd step:

Walnut after the immersion treatment is really carried out aeration-drying, remove the moisture content on the shell fast, and adhesive solvent is concentrated until curing in drying.

The 4th step:

Further carrying out drying so that the moisture content of kernel is reduced to below 5% with known method behind the adhesive solidification, kernel breaks away from dry contraction process by adhesive and has been solidificated in benevolence skin on the shell; Naked walhut is made.

The 5th step:

With the naked walhut processing of peeling off, the naked benevolence of walnut that can be sloughed part benevolence skin through the letter sorting classification, can obtain the naked benevolence of other walnut of different size classes, and the walnut kernel of not sloughing the benevolence skin is handled by prior art.

The 6th step:

The naked benevolence of walnut is packaged into commodity to circulate.

Embodiment two:

Embodiment one preceding four is gone on foot the naked walhut of being processed, the process program maturations in current four steps reach more than 50% even when higher to benevolence skin clearance in the 5th step card, and when benevolence skin clearance is comparatively stablized, can directly naked walhut be come into the market to circulate as commodity.

Embodiment three:

The walnut of embodiment one first three step processing is directly entered the manufacturing procedure of peeling off behind adhesive solidification, peelled off the benevolence skin of part walnut kernel when peeling off, all the other benevolence skins are under the not further dry situation of walnut kernel, can be by hand continue to tear decorticating and become the higher naked benevolence of bright walnut of moisture content, make commodity through conventional technology sterilization packaging and circulate by taking the photograph the subclass instrument.

Embodiment four:

With the walnut of the technology in one first three step of embodiment in the processing of embodiment three, when current three step process scheme maturation needn't just can all be removed on the walnut kernel benevolence skin by instrument in embodiment three, then can peel off circulated its direct quick-frozen as bright naked walhut commodity.

More than narrated such production process with the processing method of four embodiment:

To adopt vacuum technique to suck adhesive solvent and immersion through the walnut that selection is share, drying be produced four kinds of walnut goods through seasoning respectively after solidifying again, the bright naked walhut of multi-flavor, and the naked benevolence of the bright walnut of multi-flavor, dried naked walhut of multi-flavor and the naked benevolence of the dried walnut of multi-flavor,
