The difference between dry extruder machine and wet extruder machine
To achieve puffing technology brings many advantages, also need to understand two different ways in dog food puffing puffing process.Pet food puffing equipment was "dry" and "wet" in two puffing equipment, one is dry puffing method, the second method is wet puffing. Dry puffing in the production and processing of raw materials needed before puffing just add water directly, without adding steam. Raw materials before entering the pre-expanded warehouse without quenching, the heat generated during puffing all the squeezing action under mechanical and electrical adjustment from raw materials, through the screw, clipboard and puffing chamber produce. The main difference between wet and dry puffing law bulked raw materials are extruded in advance before entering the quenching, by steam or water to raise the temperature, pre-curing. The so-called quenching, is that by the action of heat and moisture vapor to feed pet dog food raw materials, the raw material in the pre-gelatinized starch, protein denaturation, softening raw material, in this way can improve the effectiveness and dog food puffing granulation expanded improve quality.
