Abstract

The invention discloses a making process of semi-dried and semi-humid longan, which includes the steps of firstly, using scissors to cut off fresh longan from clusters picked on the day one by one, and selecting longan fruits which are large and mature with rich pulp, secondly, pouring the longan fruits into a cleaner to clean dust and sundries on the surfaces of the longan fruits; thirdly, placing the cleaned longan fruits in an oven with kept temperature of 65-70 DEGC for primary baking, and taking out the fruits for heat dissipation when the fruits are 60% fried; fourthly, placing the longan fruits primarily baked and cooled in a cold store at 3-4 DEG C for storage for 1-2 days; fifthly, placing the longan fruits kept in cold storage for a period of time in the oven at 55-60 DEG C for re-baking for 16 hours, and obtaining the finished longan. The semi-dried and semi-humid longan has proper water content, the pulp of the longan is golden yellow, semitransparent and crystal, and the flavor of the fresh longan is kept well.

Description

A kind of manufacture craft of half-dried wet type dried longan

Technical field

The present invention relates to a kind of production technology, particularly relate to a kind of manufacture craft of half-dried wet type dried longan.

Background technology

Dried longan is claimed dried longan again, and flavor warm in nature is sweet, heart-spleen boosting; Fill blood, have the nourishing benefiting action is well arranged, current social work, life stress are big; Make us be in sub-health state often; And often edible dried longan can be used for the insomnia due to the insufficiency of the spleen damage of the heart, the insufficiency of vital energy and blood, forgetful, palpitation with fear, disease such as dizzy, so the market of dried longan is very broad; The dried longan of traditional handicraft processing because its processing is extensive, thereby causes the bad change of dried longan color and luster that processes, and nutritive loss is serious, and pulp is shrivelled, and edible quality is low.

Summary of the invention

In order to address the above problem, overcome the deficiency of prior art, the present invention proposes a kind of manufacture craft that makes the half-dried wet type dried longan that the dried longan moisture is moderate, pulp is golden yellow translucent sparkling and crystal-clear shape, mouthfeel is good.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of manufacture craft of half-dried wet type dried longan comprises following processing step:

1), choosing fruit: select the bright longan of plucking the same day for use and cut the fruit grain from fruit ear by grain, choose from the fruit grain that fruit shape is big, meat is thick, mellow fruit with scissors;

2), clean: pour garbled longan fruit into fruit grain cleaning machine, the dust and the foreign material of wash clean longan fruit epidermis;

3), baking just: the longan fruit of wash clean is put into the baker that temperature remains 65-70 ℃ cure, treat that the fruit sixty percent dried back that completes just can take out and dispel the heat;

4), refrigeration: will just drying by the fire longan fruit after the heat radiation, to put into temperature be that 3-4 ℃ freezer stores 1-2 day;

5), baking again: the longan fruit that will refrigerate a period of time is put into the baker that temperature remains 55-60 ℃ and is cured, and cures after at least 16 hours and just can make finished product.

Further, above-mentioned steps 3) longan fruit in turns over fruit once after curing 8 hours, at a distance from 5 hours after, turn over fruit more once, turns over baking through 1 to 2 time, cures round the clock, after 24 hours, treats that longan fruit sixty percent dried completing then just can take out and dispel the heat.

Further, above-mentioned steps 5) in longan fruit in baking process again, need at least whenever to stir 1 time at a distance from 2 hours.

The invention has the beneficial effects as follows: the half-dried wet type dried longan moisture of utilizing technology of the present invention to cure out is moderate, and pulp separates with shell, and base of fruit links to each other; Pulp is golden yellow translucent sparkling and crystal-clear shape; Simultaneously can more intactly keep the local flavor of former bright longan, a refrigeration step has been arranged in the manufacturing process steps of the present invention in addition, longan abound with unsalable in; The orchard worker can just dry by the fire the back stored refrigerated that completes with bright longan; Longan fruit is taken out reprocessing and sell in certain suitable time period, avoid causing price too low and infringement orchard worker's economic interests have been protected the orchard worker better because longan is abounded with.

The specific embodiment

For ease of the present invention is further understood, combine specific embodiment to describe the present invention at present.

1), choosing fruit: select for use the same day from setting the fresh longan fruit ear of plucking; Longan fruit is cut by grain from fruit ear through the manual mode of scissors of using then; Then the longan fruit of cutting being put into fruit grain screening machine again screens; Therefrom filter out the fruit longan fruit that shape is big, meat is thick, ripe, remove the fruit that those shells have damage at the longan fruit that filters out again at last, and throw away those decayed fruits and hypogenetic fruitlet; Above-mentioned fruit grain screening machine is preferentially selected the grader of one-level for use, selects for use other graders also passable certainly;

2), clean: garbled longan fruit is poured in the fruit grain cleaning machine cleaned; The dust and the foreign material of wash clean longan epidermis; Above-mentioned steps 1) choosing fruit and step 2) cleaning preferentially be arranged on the production line; Help to enhance productivity, it is also passable separately to be arranged on other places certainly;

3), baking just: the longan fruit of wash clean is poured on the sieve and flattens, then longan fruit is put into baker and kept the temperature of baker between 65-70 ℃, longan fruit to be cured with vigorous fire, after curing 8 hours; To turn over fruit to longan fruit 1 time; After 5 hours, turn over fruit again 1 time, cure, cure round the clock through 1 to 2 time the fruit that turns over; After 24 hours, treat that the moisture of longan fruit removes 40%, the back that completes just can take out and let longan fruit lower the temperature at circulation of air place natural heat dissipation;

4), refrigeration: will just dry by the fire longan fruit behind the radiating and cooling and put into the freezer storage 1-2 that temperature remains 3-4 ℃ and just can take out after day;

5), baking again: will refrigerate the longan fruit of 1-2 after day and put into baker and cure; At this moment then baker is heated and its temperature is remained between 55-60 ℃ with slow fire; Longan fruit cured just can make finished product after at least 16 hours, above-mentioned curing needs in the process whenever just longan fruit to be overturn 1 time at a distance from 2 hours at least.

The dried longan moisture that adopts half-dried wet type dried longan manufacture craft of the present invention to process is moderate; Face shaping and color are basic similar with bright longan, and pulp separates with shell, and base of fruit links to each other; Pulp is golden yellow translucent sparkling and crystal-clear shape, keeps bright longan that local flavor was arranged originally basically.

The above is merely preferential embodiment of the present invention, as long as realize that with basic identical means the technical scheme of the object of the invention all belongs within protection scope of the present invention.
