2, the influence that packs pair of weight loss
Pack appropriately can reduce a product to dehydrate, the function that these packing is in the product all around place content of a protective screen to be in in order to reduce air the flow of product surface, reduce thereby dehydrate. The simplest way is to use repellent lid to pile in the product, or product sack, box or carton inside. The concentrated accumulation of the product also can control air to be all round product of one by one flow, although enter the product in net bag to also can have a few profit, because be inside bag,each individual product gather together are together, form a concentrated accumulation, interiorly is protected outerly and so more product is avoided it is at be being exposed directly in dry air.
The ooze sex that packs pair of vapor and those who enclose is concentrated degree can decide the product dehydrates rate can fall the degree of paper. It is certain that the commonly used material that pack is had to vapor osmotic, get together of second thin film osmotic low, can better land controls a product to dehydrate, of carton and paper bag osmotic taller, but with compare without the bulk product photograph that pack, also can decrease greatly dehydrate quantity. Consequently, people often uses plastic film and stencil to wait osmotic low stuff packages a product. Basic method has the following kinds: (1) will single product or a certain number of the course of study since product package, reentry enters container inside; (2) in putting the product in the bag that these material make; (3) entire line is added on the wall of container with these material; (4) besmear to avoid inside carton a candle or become the recycle after beaverboard dip candle the case that pack first.
Return the ability that should notice to pack material imbibe. All sorts of paper products, gunny-bag and other and natural fiber, just give naked eye to look those who come out is wetly after drawing a lot of water shares. Because there often is a vapor to press difference between product and packing, then, water portion evaporates to be absorbed what come out to package data from the product. In the discovery in the cold storage of apple and pear, a water that 4 kilograms of serious dry wood cases can absorb about 500 grams below 0 ℃ , using so osmotic should notice to raise its humidity before tall container. When weather is dry, can be in conciously go up of easy the wooden case of dehydrated fruit vegetables product, attrib wattle one's store of valuables or basket sprinkle a bit water, direct and wet pack what also can use extra water share to evaporate help product is cooling.
3, the refrigeration of the product inside container
Significant to another when pack demand is to must be helpful for a product cooling quickly. The pad that uses inside the box that pack, mount and other Xiaobao are installed, the respiration heat that the model of shade cropland track that produces size to differ circularly to air affects product place to arise sends out go out to want product respiration only actually exuberant, no matter the product is,in single bag case still is in the package that piles up thick and fast, natural metropolis becomes serious.
