Description
Technical field
The present invention relates to a kind of preparation technology of eucommia ulmoides male flower tea.
Background technology
Enhancing and going deep into bark of eucommia understanding along with health of people consciousness, the eucommia ulmoides male flower tea of doing raw material with eucommia Bark male flower more and more is subjected to people's high praise and favor, the deficiency of like product on production technology in the market, seriously restrict output and the quality of eucommia ulmoides male flower tea, thereby be difficult to satisfy people to the consumption demand of eucommia Bark male flower tea product.The production technology of like product is development and evolution from the production technology of Xinyangmaojian tea in the market, production technology is specific as follows: harvesting → fractionation → airing → fried green → toast → pick screening → minute grade packaged, this production technology is immature, has caused following problem: male flower bud utilization rate is low; In the split process because human factor so that the effective ingredient of male flower pistil partly run off, thereby affected the quality of whole product; The stirring work that the airing area is crossed in ambassador's airing process is difficult to carry out thoroughly cause a part of raw material to generate heat in the airing process, turns black even goes bad, and then affected the quality of whole product; Promoted the amount of labour used, the cost of stepping up its investment.
In the patent document of publication No. CN102178007A, a kind of comparatively preparation method of ripe eucommia ulmoides male flower tea is provided, but the harvesting step of eucommia Bark male flower has not been carried out effective technological improvement.Existing eucommia Bark male flower is plucked technology and can only be taked one to stay one or the pattern of plucking the branch bud of suitably pruning with averruncator to bud on the wall scroll branch on the gutta-percha tree.These two kinds of harvesting patterns cause male flower bud utilization rate can only remain between the 30%--50%, cause to a great extent the existing resource waste; Adopted the airing step, the amount of labour used, the occupation of land amount improves greatly, has increased the cost input; Knead into the step of aciculiform, no matter adopt artificial or mechanically actuated, bud has been caused mechanical damage to a certain degree, and so that nutritional labeling has certain loss.
Summary of the invention
It is high to the purpose of this invention is to provide a kind of natural resource utilizing rate, the preparation technology of eucommia ulmoides male flower tea with low cost
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of preparation technology of eucommia ulmoides male flower tea is characterized in that, may further comprise the steps:
A: when not having dew in the tree, stay one principle according to adopting five, pluck the full flower bud of male flower bud, be placed in the bamboo basket;
B: with the full flower bud of male flower bud 0-5 ℃ lower fresh-keeping, until be positioned in-20 ℃--18 ℃ the cold storage environment;
C: with the full flower bud of male flower bud of B step gained under-40 ℃--30 ℃ temperature, freezing 4-6 hour;
D: the full flower bud of male flower bud of C step gained be not higher than under-45 ℃ the environment freeze drying 25-35h;
E: behind the full flower bud vibrosieve of male flower bud with D step gained, under 140-150 ℃ temperature, constant temperature baking 3-5 minutes;
F: with the sealing of E step products therefrom, in 0-5 ℃ environment, leave standstill moisture regain 40-60 days;
G: under 110-130 ℃ temperature, constant temperature baking 2-5 minutes is down to 40 ℃ with the temperature of the product after the baking with F step products therefrom, again crosses the vibratory sieve removal of impurities, and with the products therefrom packing, eucommia ulmoides male flower tea gets product.
Adopt five and stay one principle, the utilization rate that makes existing resource is brought up to about 80% by original 30%-50%.Save the step of airing, saved and taken up an area the airing input of taking a lot of work, and avoided because the material waste that artificial factor causes in the airing process.Fresh-keeping measure, quick-frozen, cryogenic temperature freezing drying technology combine, through practical proof, and the nutritional labeling of having preserved to greatest extent the eucommia Bark male flower raw material.
Preferably, among the step C, with the full flower bud of described male flower bud under-38 ℃--35 ℃ temperature, freezing 5 hours.
Preferably, among the step D, the full flower bud of described male flower bud under-60--50 ℃ temperature, freezing 30h in freeze dryer.
Preferably, in the step e, during vibrosieve, the full flower bud of described male flower bud crosses 8 orders, 14 orders, 45 mesh sieves successively, and screen cloth products therefroms at different levels are collected respectively.The screening from large to small of different meshes and screen cloth can be sieved out the impurity of carrying secretly in the raw material to greatest extent, simultaneously thick tea bar, thin tea bar and pollen is sieved out, class wrapping, and make the product that does not become and sell, improved resource utilization, the value of the product of also having made rational planning for.
Preferably, the sieve afterproduct collected under 143 ℃, was toasted 4 minutes.
Preferably, among the step G, the product after the described moisture regain was toasted 4 minutes at 118 ℃ of constant temperature.
Preferably, the product after the baking is crossed 12 orders, 14 orders, 60 order vibratory sieves successively, and with after the screen cloth products therefrom at different levels removal of impurities, pack respectively.Again screening, removal of impurities and product classification work are more careful.
The present invention compared with prior art has following advantage: technology maturation, the nutritional labeling of having preserved to greatest extent the eucommia Bark male flower raw material; Efficient harvesting technology has improved the utilization rate of male flower resource; Whole production technology work consuming amount reduces greatly, has reduced the cost input; Effectively the product classification of removal of impurities measure and different brackets is packed, and has reasonably planned the value of product, has promoted the positive image of enterprise.
