Description
Technical field
The invention mainly relates to wrapping paper processing technique field more particularly to a kind of antibacterial egg trays.
Background technique
Egg tray can play the role of fixed and protect egg, and egg tray currently on the market is generally papery and plastics
Two kinds, the egg tray of plastic components can only play simple fixed function, and the egg tray hardness of papery is larger, can be to avoid egg
Mutual extrusion, but while jolting, is easy to generate collision to egg, it is damaged to make egg shell, and the egg tray of papery is simultaneously
Not having antibacterial action, the nutritional ingredient of egg liquid is high, corruption will most probably occur after eggshell crack during transportation, and
And corruption can also occur by other eggs that egg liquid is infected with, cause unnecessary economic loss.
Summary of the invention
In order to make up the defect of prior art, the object of the present invention is to provide a kind of antibacterial egg trays.
A kind of antibacterial egg tray, is made of raw material from the following weight: wheat stalk 47 ~ 49, corn stover 36 ~ 38, pine
Needle 12 ~ 14, nano zine oxide 4 ~ 6, chitosan 1.3 ~ 1.5, dandelion extract 0.6 ~ 0.8, complex enzyme 0.02 ~ 0.03.
The pine needle, for the pine needle to fall off naturally from pine tree, being dried up naturally to water content is 10 ~ 12%.
The dandelion extract, dandelion is cleaned, and crushes, and the volume point of 60 ~ 70 times of dandelion weight amounts is added
3 ~ 4h is extracted in the alcoholic solution that number is 66 ~ 68%, concussion, and the water of 40 ~ 50 times of filter residue weight amounts is added into filter residue, boils for filtering
Being decocted afterwards to volume is original 1/10, and filtering merges all filtrates, and being dried to water content is 8 ~ 10%, obtains dandelion extraction
Object.
The complex enzyme is made of the raw material of following parts by weight: hemicellulase 18 ~ 20, lignoenzyme 15 ~ 17, rouge
Fat enzyme 13 ~ 15, amylase 2 ~ 4.
A kind of preparation method of antibacterial egg tray, comprising the following steps:
(1) wheat stalk, corn stover and pine needle being crushed to 4 ~ 6mm, are added to the water, solid-liquid ratio is 1:2 ~ 3, it is uniformly mixed,
Complex enzyme is added, digests 2 ~ 3h in 43 ~ 45 DEG C of heat preservations, material must be digested；
(2) whiterot fungi is accessed into enzymatic hydrolysis material, access amount be the 6 ~ 8% of enzymatic hydrolysis material weight, is uniformly mixed, in 31 ~ 33 DEG C of fermentations 15
~ 17d, obtains fermentation material；
(3) nano zine oxide, chitosan and dandelion extract are added in fermentation material, are placed in 70 ~ 80 DEG C, 42 ~ 46r/min stirs
50 ~ 60min is mixed, egg tray mixing slurry is obtained；
(4) egg tray mixing slurry is divided into upper layer slurry and lower layer starches, upper layer slurry is the 1/3 of egg tray mixing slurry weight, lower layer's slurry
It is the 2/3 of egg tray mixing slurry weight, upper layer slurry and lower layer's slurry is beaten respectively, is conventionally formed, is obtained
Just at egg tray；
(5) heating zone that will be just 70 ~ 80 DEG C by temperature at egg tray, the residence time is 15 ~ 20s, then is arranged and wrapped
Dress, obtains antibacterial egg tray.
The mashing of the step (4), upper layer slurry beating degree be 30 ~ 32 ° of SR, beating consistency 6.4 ~ 6.6%, lower layer slurry
Beating degree is 35 ~ 37 ° of SR, beating consistency 13 ~ 15%.
The molding of the step (4) first forms lower layer's slurry, and upper layer slurry is then laid on molding lower layer's slurry table
Face, upper layer density are 0.7 ~ 0.9g/m3, lower layer density is 5.1 ~ 5.3g/m3。
The application method of the antibacterial egg tray, upper layer slurry is directly contacted with egg when use.
The invention has the advantages that antibacterial egg tray provided by the invention, upper layer is soft, and lower layer is hard, can effectively avoid transporting
Eggshell crack caused by process moderately gusty air, bearing capacity is strong, indeformable, and bacteriostasis rate reaches 92.7%, and the corruption of egg is effectively avoided to become
Matter reduces a large amount of economic loss；It is primary raw material by wheat stalk, corn stover and pine needle, it is from a wealth of sources, turn waste into wealth,
Natural antibacterial action can be played, is digested after crushing, the impurity in raw material is decomposed, improves the purity of cellulose；Enzymatic hydrolysis
Enter whiterot fungi afterwards to ferment, further decomposes lignin, improve the purity and yield of cellulose, it is environmentally protective；After fermentation
Nano zine oxide, chitosan and dandelion extract are added, it is safe and non-toxic, it is green and healthy, the antibacterial action of slurry is improved, is made
Egg tray intensity with higher after molding, bearing capacity is strong, indeformable, is easy to the transport of egg；Again by egg tray mixing slurry
Be divided into upper layer slurry and lower layer slurry, to upper layer slurry and lower layer slurry be beaten respectively, control upper layer slurry and lower layer slurry beating degree and
Beating consistency keeps egg tray upper layer after molding soft, and lower layer is hard, avoids transport from jolting and causes eggshell crack, enhances to chicken
The defencive function of egg；It is finally dried by heating zone, while chitosan can be promoted to melt, cellulose is made to be combined with each other tightly
It is close, improve the intensity of egg tray；The soft layer on upper layer is directly contacted with egg when use, improves egg tray to egg
Protecting effect.
