The double-screw extruder of is a novel extruding machine designed and manufactured by the company to adapt to the demands for increasingly-developing food and related industries by relying upon years of experience in puffing process research. The extruder complies with international quality standard and their key parts and components are imported from abroad. Computer program and automation design are applied in the extruder control system to achieve optimal parameter setting according to different formulas, water contents, pressure, temperature and the like of the processed products, it has simpler and more reliable working process, rewarded national major new product, and it was recommended as famous and excellent food machinery by China Food and Packaging Association of Electrical and Mechanical Department.

The double-screw extruder is composed of a feeding system, an extruding system, a cutting system, a heating system, a cooling system, a drive system and a control system; it is possible to realize automatic continuous production without manual adjustment by setting production parameters.

The extruder can process a variety of raw materials, including corn powder, rice powder, wheat powder, mungbean powder, sweet potato powder, meat powder, fish powder and various starches. Users may adjust texture and puffing conditions of products by adjusting production process parameters; and output products of various shapes by replacing screws or moulds to satisfy customers requirements for products to the largest extent.

The complete extrusion line is developed with the 1990s advanced technology of west europe by our company. The main machine is single screw extruder with cossponding downstream equipment.

Mini/Small/Lab Twin Screw Plastic Sheet Extruder
 Machine features of Mini/Small/Lab Twin Screw Plastic Sheet Extruder:

The main extruder adopts the principle of building block design, combined with the requirements of product process characteristics, the length-to-diameter ratio of the screw, the structure of the barrel, the changing of the mesh, the form of pelletizing, and the automatic control mode can be flexibly matched. With the rich experience and software technology of screw configuration research and development, the screw configuration can be designed as needed to realize material transportation, mixing and homogenization, shear dispersion, exhaust devolatilization, and pressure extrusion.

Optimized design combined with CNC machining methods to improve product accuracy and achieve a new level of manufacturing precision for key components, enabling better control of the host process, high consistency and flexibility. Interchangeability enables higher precision of the three-dimensional surface of the screw element and superior self-cleaning.

  The realization of the precision and quality of conventional and high-torque hard-toothed gearboxes has been improved. The overall reliability and quality stability have reached the domestic leading level. Combined with strong design experience, the special prayer structure and screw components have Processing and manufacturing platform.
