Abstract

The invention relates to the technical field of fruit deep processing, and particularly relates to a preparation method of dried longan. The method specifically comprises the steps of material selection, particle cutting, water soaking, excess shaking, primary baking, secondary baking, base cutting, classification and packaging to obtain the finished product. According to the method provided by the invention, by adding clean fine sand in the excess shaking process and in combination with the shake, the shell is thin and smooth and convenient to dry. Meanwhile, the processing process of the longan has short period and high efficiency, and the yield is very high. By adopting the method provided by the invention, the production cost of longan in the processing process is low, and the method is very suitable for the factory-like, large-scale and intensive production of the dried longan.

Description

A kind of processing method of dried longan
Technical field
The present invention relates to a kind of fruit deep process technology field, be specifically related to a kind of processing method of dried longan.
Technical background
Longan is the ground such as southern china fruit, distribution Fujian, Taiwan, Guangdong, Guangxi, Yunnan, Guizhou, Sichuan.Dry longan claims again dried longan, and dried longan has another name called intelligence development, arillus longan, is the ripening fruits of longan.Property is put down, and taste is sweet, contains the chemical analysis such as thiamine, riboflavin, niacin, ascorbic acid, has blood-enrich, tranquilizing the mind, the effect of nourishing blood and preventing abortion.Be applicable to insomnia forgetfulness, insufficiency of the spleen diarrhoea, the diseases such as lassitude.Dried longan function cures mainly: heart-spleen boosting, fill blood, and the will of calming the nerves.Cure mainly consumptive disease thin and weak, palpitaition is appointed sad, insomnia forgetfulness, insufficiency of the spleen diarrhoea, postpartum edema, lassitude, the illnesss such as spontaneous sweating.Deeply to be subject to tonic food , China various places that consumers in general welcome all to have very large consumption market.Moisture in longan fruit is growth of microorganism breeding conditio sune qua non.Do not having under the condition of moisture, microorganism can not growth and breeding.The moisture that contains 50%-70% in longan fruit, contains again various nutriments, and as sugar, protein, vitamin etc., this is the natural high-quality culture medium of microorganism.The roasting of dried longan, is, by thermodynamic activity, the moisture in fruit is reduced to certain limit, makes the concentration of its solable matter bring up to the degree that microorganism is difficult to utilization.Because dried longan reduces through thermodynamic activity moisture, the active of enzyme is also suppressed simultaneously, so can carry out the preservation of long period.
At present, mostly the processing method of dry longan is fresh longan to obtain through manually drying finished product.This method process-cycle is long, efficiency is low, yield rate is not high, causes production cost high.
Summary of the invention
Object of the present invention is exactly to overcome the deficiency of above-mentioned technology and processing method that brand-new a kind of dried longan is provided.Specifically comprise: shake → just roasting of the grain → immersion of selecting materials → cut → cross → roast again → the cut base of a fruit → classification → packing, and finished product.By implementing the present invention, can make that shell is thin to polish crossing to add clean fine sand to coordinate in shaking process to shake, be convenient to dry.Meanwhile, not only the cycle is short, efficiency is high in process for longan, and yield rate is very high.Implement the present invention, longan is low at process production cost, is applicable to very much dry longan batch production, scale, intensive production.
Invention is achieved through the following technical solutions:
A processing method for dried longan, comprises the steps: in technical scheme
1, select materials: select abundant maturation, a fruit complete longan fruit.
2, cut grain: fruit grain is cut from fruit ear, and staying stalk length is 1.5 millimeters, rejects broken fruit.
3, immersion: fruit is put into bamboo square-bottomed bamboo basket, then connect bamboo square-bottomed bamboo basket and be put into soak in clear water and dust cleaned in 5~10 minutes.
4, cross and shake: the fruit of soaking is poured into and shaken in cage, 35~40 kilograms of every cage mounteds are sprinkled into 500~600 grams of clean fine sands in shaking cage, then will shake cage and sway rapidly 10~12 minutes, make fruit constantly rolling friction in cage, treat that shell transfers the brown and dry cage that can stop shaking to.
5, just roasting: fruit is layered on roasting kitchen range equably, is 15~18 centimetres along paving thickness, and rear edge is 10~12 centimetres, and then heating is cured, and stirs once for 6~8 hours, can play roasting again after stirring for the second time after 3~5 hours cure.
6, roast again: through the dried longan of just roasting processing, place after 2~3 days, fruit stone and pulp moisture are gradually to external diffusion, pulp surface water content increases while going out to roast than just, need again cure, palpus slow fire while curing again heating, the time is 10~12 hours, centre is stirred for several times, when pressing fruit to flow out, cut rear fruit stone open and be Chestnut without fruit juice with finger, can go out roasting, need to dispel the heat 20~24 hours after going out roasting.
7, cut the base of a fruit: the carpopodium that cuts off dried longan with scissors.
8, classification: the longan fruit grain drying is sieved, carry out by size classification.
9, packing: the longan fruit grain that classification is good is sub-packed in polybag according to quantity, finally plastic bag mouth sealing is obtained to finished product.
Tool of the present invention has the following advantages:
1, dried longan processing method technique proposed by the invention is simple, easily implements.
2, by implementing the present invention, can make that shell is thin to polish crossing to add clean fine sand to coordinate in shaking process to shake, be convenient to dry.
3, by implementing the present invention, not only the cycle is short, efficiency is high in process for longan, and yield rate is very high.
4, by implementing the present invention, longan is low at process production cost, is applicable to very much dry longan batch production, scale, intensive production.
The specific embodiment
Below in conjunction with embodiment, method of the present invention is further illustrated.
A processing method for dried longan, the specific embodiment is as follows:
1, select materials: select abundant maturation, a fruit complete longan fruit.
2, cut grain: fruit grain is cut from fruit ear, and staying stalk length is 1.5 millimeters, rejects broken fruit.
3, immersion: fruit is put into bamboo square-bottomed bamboo basket, then connect bamboo square-bottomed bamboo basket and be put into soak in clear water and dust cleaned in 5~10 minutes.
4, cross and shake: the fruit of soaking is poured into and shaken in cage, 35~40 kilograms of every cage mounteds are sprinkled into 500~600 grams of clean fine sands in shaking cage, then will shake cage and sway rapidly 10~12 minutes, make fruit constantly rolling friction in cage, treat that shell transfers the brown and dry cage that can stop shaking to.
5, just roasting: fruit is layered on roasting kitchen range equably, is 15~18 centimetres along paving thickness, and rear edge is 10~12 centimetres, and then heating is cured, and stirs once for 6~8 hours, can play roasting again after stirring for the second time after 3~5 hours cure.
6, roast again: through the dried longan of just roasting processing, place after 2~3 days, fruit stone and pulp moisture are gradually to external diffusion, pulp surface water content increases while going out to roast than just, need again cure, palpus slow fire while curing again heating, the time is 10~12 hours, centre is stirred for several times, when pressing fruit to flow out, cut rear fruit stone open and be Chestnut without fruit juice with finger, can go out roasting, need to dispel the heat 20~24 hours after going out roasting.
7, cut the base of a fruit: the carpopodium that cuts off dried longan with scissors.
8, classification: the longan fruit grain drying is sieved, carry out by size classification.
