Abstract
The invention relates to a preparation technology for making fruit residue paper for marc fiber, which is characterized in that: firstly, the dry fruit residue or wet fruit residue is untwined; and then the wood pulp or the reed pulp is implemented with pulping processing by a pulping machine; finally, the fruit residue is mixed with the wood pulp or the reed pulp, and then which is added with rosin size, aluminium sulphate and PAM, and is made in the method of shaping in one time. The preparation technology is that the making is implemented by mixing fruit residue fiber with plant fiber. The fruit residue fiber is implemented with the pretreatment of sugar washing, light untwining, filtering and purifying, and which is untwined and mixed with the processed plant fiber in sequence, and then which is added with chemical additives, so the fruit residue paper is made in a conventional way. The product has the advantages that: the used product is easy to be decomposed without environment pollution; simultaneously the environment pollution caused by waste residue is reduced; the waste residue can be burnt or taken as compost, which also can be recycled for paper making; thereby the product can be used in general food packaging.
Description
Technical field
The invention belongs to the crossing domain of paper industry and food industry, be specifically related to a kind of pomace fiber be used to manufacture paper with pulp preparation technology of pomace paper.
Background technology
China be fruit tree origin the earliest, one of country that types of fruits is the abundantest, also be fruit big producing country in the world, total output occupies first place, the world.Wherein produce more than 2,000 ten thousand tons of apples per year, about 20% are used for fruit juice processing, produce about 1,000,000 tons of pomace per year.Fruit juice factory all is used as pomace as refuse and abandons for a long time.Because the pomace moisture is up to more than 70%~80%, and contain the rich soluble nutriment, created suitable condition for the breeding of growing of microorganism, the pomace of abandoning can be rotted at short notice, souring is fouled, and has caused the very big pollution of environment and the huge waste of resource.
Pomace is made up of pericarp, fruit stone and remaining pulp, contains multiple materials such as soluble sugar, vitamin, mineral matter, cellulose, utilizes pomace can extract pectin, dietary fiber, production jam, alcohol, citric acid, compound sugar, enzyme preparation etc.But domestic present great majority well do not utilize.According to investigations, Shaanxi Province accounts for 15%~20% with what pomace was made fertilizer, fuel at present, used as fodder be about 10%, when garbage disposal account for 70%, annual so nearly 100,000 tons~150,000 tons pomaces waste, but also serious environment pollution.Making full use of the discarded resource of this class is the problem of a reality.
Summary of the invention
The object of the present invention is to provide a kind of this class waste resource of pomace that makes full use of as the papermaking raw material, preparation technology is simple, and the pomace fiber that can give the better solubility property of paper when guaranteeing paper physical property again be used to the to manufacture paper with pulp preparation technology of pomace paper.
For achieving the above object, the technical solution used in the present invention is: at first the dry fruit slag is soaked more than the 24h, discongest revolution and be the 500r pomace that maybe will wet and directly discongest revolution 300r; Then wood pulp making beating 1000 in PFI mill is changeed, the making beating gap is 0.2mm, the mass concentration 10% of making beating, beating degree≤48 ° SR or get reed pulp and carry out in the Valley beater, reed pulp beating degree≤35 ° SR; To the wood pulp or the reed pulp of 50%~60% pomace and 40%~50% be mixed by mass ratio at last, the gum rosin that adds mixture quality 2.0% then, 2.0% aluminum sulfate, 0.08%~0.10% PAM, the online mass concentration of regulating mixed slurry is 0.3%, manufactures paper with pulp according to the mode of once-forming.
The present invention manufactures paper with pulp by the pomace fiber is mixed with string.The pomace fiber is carried out sugar part washing, slightly discongests and screen the purification preliminary treatment, discongest sequentially with treated string and mix, add chemical assistant, adopt conventional forming mode to manufacture paper with pulp into paper.Product uses the back to decompose easily, is difficult for contaminated environment, reduces the pollution of pomace discarded object to environment simultaneously, can burn or do compost, and also recyclable papermaking again can be used for the bread and cheese packing.
