Abstract
The invention discloses a kind of disposable instant fructus lycii systems to do new method, fresh fructus lycii after picking breaks wax through 1-3% sodium carbonate, it is rinsed again through clear water, it is put into microwave drying oven, under condition of negative pressure, successively through being dehydrated under 35 DEG C, 45 DEG C, 60 DEG C of microwave irradiations to fructus lycii moisture content≤8%, it is then naturally cooling to room temperature, can be packed.The present invention carries out microwave drying to fructus lycii using 35 DEG C, 45 DEG C, 60 DEG C of temperature gradients, most of moisture is first removed under cryogenic, temperature is stepped up again to be further dehydrated, substantially reduce dewatering time, dewatering time is substantially reduced, fructus lycii is constant in microwave action following table, inner temperature, uniform drying, condition is uniform, prevented from caking.Drying efficiency is greatly improved, while also ensuring the sanitary condition of product, also improves product quality.
Description
Technical field
The invention belongs to field of agricultural products processing more particularly to a kind of fresh fructus lycii drying methods.
Background technique
It is main and important one of measure during fructus lycii is long time stored that fructus lycii system is dry.For many years, traditional fructus lycii system
Drying method dries system under natural environment and does, and natural drying takes a long time（6-10 days）, and be easily contaminated by dust, in addition,
Naturally the dry fructus lycii coloration of system deepens, meat is hardened and fold is irregular, and moisture content height is different, stores easily knot to long-time
Block has great risk, has seriously affected the quality of fructus lycii, can not be directly edible as instant fructus lycii.At present also some
It is dry that system is processed by therrmodynamic system, though heating power system is dry to do efficiency and quality-improving much compared with natural drying system, in heating power system
During dry, fructus lycii need to be stirred, fructus lycii broken skin is easily caused, the sugar in heating power dry wolfberry fresh fruit is easy to overflow, and leads to fruit
Bonding, influences quality.Both above method cannot all guarantee Lycium barbarum. L Quality very well, during instant, also need to reprocess.
Summary of the invention
The purpose of the present invention is overcome the deficiencies of the prior art and provide a kind of dry new method of disposable instant fructus lycii system.
To achieve the goals above, the technical solution adopted by the present invention is：
A kind of disposable instant fructus lycii system does new method, it is characterised in that step is：Fresh fructus lycii after picking is broken through 1-3% sodium carbonate
Wax, then rinsed through clear water, it is put into microwave drying oven, under condition of negative pressure, successively through taking off under 35 DEG C, 45 DEG C, 60 DEG C of microwave irradiations
Then water is naturally cooling to room temperature, can pack to fructus lycii moisture content≤8%.
35 DEG C of microwave irradiating times are 30-40min, can slough about 55% moisture.
45 DEG C of microwave irradiating times are 20-30min, can slough about 30% moisture.
60 DEG C of microwave irradiating times are 10-20min, can slough about 10% moisture.
The drying method processed of disposable instant dry wolfberry of the invention, in microwave drying process, using 35 DEG C, 45 DEG C, 60 DEG C
Temperature gradient carries out microwave drying to fructus lycii, first removes most of moisture under cryogenic, then to step up temperature further
Dehydration, substantially reduces dewatering time, fructus lycii is constant in microwave action following table, inner temperature, and glass does not occur in uniform drying, endoplasm
Matter, condition is uniform, and active constituent is not destroyed, prevented from caking.Drying efficiency is greatly improved, while also ensuring defending for product
Carded sliver part, also improves product quality.
Specific embodiment
Embodiment 1

After point, fructus lycii is put into microwave drying oven, microwave drying oven installs an air inlet and a venthole additional, and connecting one can
The asepwirator pump of tune revolving speed makes microwave drying oven drying process have certain negative pressure, by disengaging air capacity adjust room temperature and
Moisture is discharged.Microwave irradiation dries 40min at 35 DEG C respectively, and the dry 20min of microwave irradiation, then micro- at 60 DEG C at 45 DEG C
Wave irradiates dry 15min, removes 55%, 29%, 10% moisture respectively, obtains the dry wolfberry that water content is 6%, after Temperature fall 2h,
The dry wolfberry that water content is 8% is finally obtained, can be packed.
Embodiment 3
By the fresh fructus lycii after picking, with pulling out after 3% soaking in sodium carbonate solution 1 minute, rinsed with clear water, sunning drains surface water
After point, fructus lycii is put into microwave drying oven, microwave drying oven installs an air inlet and a venthole additional, and connecting one can
The asepwirator pump of tune revolving speed makes microwave drying oven drying process have certain negative pressure, by disengaging air capacity adjust room temperature and
Moisture is discharged.Microwave irradiation dries 35min at 35 DEG C respectively, and the dry 30min of microwave irradiation, then micro- at 60 DEG C at 45 DEG C
Wave irradiates dry 10min, removes 57%, 31%, 10% moisture respectively, obtains the dry wolfberry that water content is 6%, after Temperature fall 2h,
The dry wolfberry that water content is 7% is finally obtained, can be packed.
