Double screw extruder(Twin screw extruder)

Product Description
It can produce various fallow foods, snacks, core-filled foods, grain gruel, nutrient powder (such as breakfast foods, nutrient foods, baby's foods, health foods). Furthermore, this equipment is widely utilized in the fields of fodder making, chemical industry, wine making, and pharmacy.  
Production capacity: 120-600kg/h 
  Main features:
Rich raw materials: such as rice, corn, millet, wheat, oats, buckwheat, bean, and starch
Diverse products: such as various fallow foods, core-filled foods, grain gruel, nutrient powder, and bread crumbs
Stable performance: adopting imported frequency or electromagnetic controlling system, high automation and smooth operation Permanent working life: with special material and technology, the screw and nut involved can work continuously for one year under conditions of high wear and pressure

Feeding system:
Spiral feeding, forced conveying, full mixing, unnecessary for moisture adjustment to ingredients, and adjustable speed of conveying

Extruding system:
The working principle is forcing the ingredients forward to be conveyed and extruded in the sealed charging barrel by making use of the engaged twin screws, at the same time, heating the ingredients through heating-cycles, the ingredients are mixed, melt and sheared step by step under the conditions of high temperature and pressure. At last the ingredients are inflated at the point of being extruded out. This system possesses self-cleaning function.

Rotary-cutting system:
The ingredients are cut by high-speed rotary cutting-off knife when they are extruded and inflated. The length of cut-off is adjustable through step-less speed regulating electrical machine.

Heating system:
The heating system is divided into several heating areas by means of far-infrared heating-cycles. The temperature of each area is automatically adjusted through separate temperature controller.

Driving system:
This system is composed of primary electric motor, reductor, distribution box, and lubrication system. Adopting imported frequency controller, it assures large regulating range, efficient power distribution, accurate adjustment, steady working as well as prolonging the working life of the components.

Controlling system:
Adopting centralized controlling, the whole process, from starting, rotary cutting, lubricating, switching off to output adjustment can be automatically operated. Automatic defender and status display device are also allocated in this system Digital display for pressure control in extruding system and temperature in heating
