Description
Technical field
The present invention relates to deoxidizing antistaling agent, be specifically related to the moistureproof deoxidizing antistaling agent of a kind of spherical tealeaves.
Background technology
Tealeaves is easy to moisture absorption and absorbs peculiar smell, accelerates the speed of oxidation, destroys nutritional labeling and original local flavor of tealeaves, need note anti-oxidation, moistureproof and prevents the pollution of peculiar smell at lay up period, to guarantee tea leaf quality.
The tealeaves optimum is stored at itself water content condition lower seal below 5%, the moisture of national Specification tealeaves≤7.5%, tealeaves when its water content 8% when above, store and just had old tea smell in 6 months; When its water content 10% the time, just be easy to occur the smell that goes mouldy; When its water content surpassed 12%, mould was easy to grow in a large number, and the smell that goes mouldy can be strengthened, even mouldy caking, can't continue to drink.
The moistureproof deoxidation preservation method of tealeaves mainly contains at present: lime dehumidifying fresh-keeping method, the nitrogen-filled packaging fresh-keeping method of bleeding, vacuum-packing fresh-keeping method, Deoxygen Packaging fresh-keeping method and damp-prrof packing fresh-keeping method; Said method cuts both ways, but all can not reach the fresh-keeping effect of moistureproof deoxidation simultaneously.
Chinese patent Granted publication CN 1181767C; On December 29 2004 Granted publication day, name is called " a kind of deoxidier of bicomponent system ", disclose " a kind of deoxidier of bicomponent system; except containing iron, sodium chloride, active carbon, water-absorbing resin; it is characterized in that: contain the zinc that matches with iron, said zinc has the oxygen uptake function with the main body of iron as deoxidier; Contain ferrous sulfate with the sodium chloride pairing; Contain active soil with the active carbon pairing; Also contain urea with the water-absorbing resin pairing; Wherein zinc-iron antithetical phrase component, sodium chloride-ferrous sulfate antithetical phrase component, active carbon-active soil antithetical phrase component and water-absorbing resin-urea antithetical phrase component, its weight proportion is respectively 50-90%, 0.1-5%, 0.5-30% and 0.1-25%.Deoxidier of the present invention can be applied to different conditions, different moisture content, different oil-containing and grade and variously do, go in the bright article, thereby obtains out and out effect ".
Sodium chloride in the above-mentioned patent, ferrous sulfate and urea all are the very strong materials of wettability power; In air, be prone to deliquescence; The finished product water content of dispatching from the factory of active carbon and active soil allows≤10.0%, these materials in the process of pulverizing and mixing, will absorbed air in a large amount of moisture content; Fast zinc, iron, active carbon, active soil and water-absorbing resin are wrapped up; Reduced the effect of deoxidier, the only fast effect of suction of competence exertion in the aqueous solution of water-absorbing resin can not effectively be adsorbed sodium chloride, ferrous sulfate, urea, variously does, the moisture content in the bright article; Therefore, the weak point of above-mentioned patent is that this technology is produced the practical effect that " a kind of deoxidier of bicomponent system " directly has influence on deoxidier.
Summary of the invention
The objective of the invention is to overcome weak point in the prior art, a kind of have protection against the tide, deoxidation, absorption peculiar smell and the fresh-keeping moistureproof deoxidizing antistaling agent of multifunctional sphere tealeaves are provided.
The moistureproof deoxidizing antistaling agent of spherical tealeaves is made up of red bentonite, dolomite Concave-convex clay rod, bauxite, sulfuric acid, high sticking Concave-convex clay rod powder and reduced iron powder.
The production method of the moistureproof deoxidizing antistaling agent of spherical tealeaves: with the batching input mixer mixing stirring of the moistureproof deoxidizing antistaling agent of spherical tealeaves, packing after stirring is spherical tealeaves protection against the tide deoxidizing antistaling agent.
Iron oxide content >=14% in the red bentonite, alundum (Al content >=10%; The content of calcium oxide >=24% in the dolomite Concave-convex clay rod, magnesian content >=12%; Alundum (Al content >=55% in the bauxite; Red bentonite, dolomite Concave-convex clay rod and bauxite are mixed into mineral intermixture; The acidified processing of mineral intermixture back generates sulfate mixtures such as part of sulfuric acid calcium, magnesium sulfate, ferrous sulfate and aluminum sulfate; Calcium sulfate, magnesium sulfate, ferrous sulfate and aluminum sulfate all have higher wettability power; Mineral intermixture with acidification carries out activation heat treatment again, has improved the moisture sorption effect of the mineral intermixture of acidification greatly.
Red bentonite originates in horse race mining area, mountain, Gui Wu town, Xuyi County, Jiangsu Province, and main component has quartz, montmorillonite, kaolinite, bloodstone and feldspar, iron oxide content >=14%; The mining area reserves have more than 1,000,000 tons; Be an opencut,, still fail the large tracts of land exploitation at present because purposes is not extensive.
The Concave-convex clay rod soil property is fine and smooth, and water imbibition is strong, and tool viscosity and plasticity help the bonding between the raw material when wet, improve the adsorption capacity and the granule strength of spherical anti-blushing agent.
High sticking Concave-convex clay rod powder is meant gets 28.0g Concave-convex clay rod powder sample; Add in the suspension cup of homogenizer, add 372g water again, the suspension cup is placed on the homogenizer; Under 11000 rev/mins of rotating speeds, stirred 20 minutes; To pass through the high-speed stirred sample suspension again and pour in the beaker of 250ml, the viscosity of using NDJ-1 type rotation viscometer to test its suspension, the Concave-convex clay rod powder of tested viscosity value >=2200 mPas is high sticking Concave-convex clay rod powder.
Reduced iron powder can absorb airborne oxygen, and 1 gram reduced iron powder deoxygenation ability is 300mL, amounts to air 1500mL, and deaerating effect is good, reduced iron powder grain fineness≤0.42 that the present invention selects for use millimeter.
Dolomite Concave-convex clay rod, bauxite and reduced iron powder are common commodity.
The present invention is achieved through following technical proposals:
1, the batching of the moistureproof deoxidizing antistaling agent of spherical tealeaves is made up of following component by weight percentage: spherical anti-blushing agent 30～70% and reduced iron powder 30～70%;
The production method of the moistureproof deoxidizing antistaling agent of spherical tealeaves: with the batching input mixer mixing stirring of the moistureproof deoxidizing antistaling agent of spherical tealeaves, packing after stirring is spherical tealeaves protection against the tide deoxidizing antistaling agent;
