How does the double screw extruder machine work？
Twin screw extruders consist of two intermeshing, co-rotating screws mounted on splined shafts in barrel. Due to a wide range of screw and barrel designs, various screw profiles and process functions can be set up according to process requirements. Hence, a double screw extruder technology is able to ensure transporting, compressing, mixing, cooking, shearing, heating, cooling, pumping, shaping, etc. with high level of flexibility. The major advantage of intermeshing co-rotating twin screw extruders is their remarkable mixing capability which confers exceptional characteristics to extruded products .

INTRODUCTION OF twin screw extruder machine FROM food processing machinery manufacturers:
|
Main Features Of Twin Screw Food Extruder Machine |
|
|
1 |
Series of double-screw extruder mainly consist of feeding system, extruding system, cutting system, heating system, lubricating system and controlling system. |
|
2 |
Transfer mixed raw materials from Mixer to co rotating twin screw extrusion |
|
3 |
Automatic lubricating and forced cooling make sure that twin extruder machine performs safely and extends using life. Feeding system, extruding system and cutting system all adopt frequency conversion timing to gain powerful drive, stable perform, and electricity saving. |
|
4 |
Screw are made of alloy and processed by special technique to possess high intensity, abrasion resistant and longer using life. |
|
5 |
By means of designing different structures and slenderness ratios according to needs of products, screw extruding system can meet different technology demands. |

THE ADVANTAGES OF TWIN SCREW EXTRUSION
|
Extruders has become the standard over time in several industries because it offers numerous advantages |
|
--- More consistency in production and control of product quality |
|
-- Increased productivity due to continuous processing, faster start up and shut down between product changes, quick changeover and advanced automation |
|
--- Greater flexibility, with the capability to process a wide range of raw materials |
|
--- Optimized footprint thanks to energy and water savings |
|
--- Simple and easy to maintain and clean |

|
The screw is an integral screw and can’t be freely combined. Different products need to be replaced with different types of screws |
twin screw extruder design can also more effectively change the screw element combination and different accurate metering feeding hopper for various material compounding.
|
|
Mixing capability of ordinary twin- screw extruders is very limited, and any flow restrictions to enhance mixing through special screw designs lead to depress the extruder throughput. |
Remarkable mixing capability, due to the interpenetration of the screws and the broad diversity of specialized screw designs (such as reverse screw elements, kneading blocks, gear mixing elements, etc.) which allow the extent of shearing/mixing to be precisely adjusted; hence leading to control the degree of mixing in regards to mixing intensity and mixing quality (dispersive versus distributive). |
|
Button control
|
PLC control Better control of process parameters, that are: narrower residence time distribution, lower dispersion of shear rates and strain, higher convective heat transfer, accurate control of temperature profile; hence leading to much better control of shear-time-temperature histories in the extruder, to much wider range of mechanical energy inputs, and so to more consistency in regards to material conversion and product quality. |
|
The V-belt drives the cutter to run, and the wear rate is high |
– Cutter with lateral movement, Highly flexible cutter The cutter can be moved to one side for easier control, access and cleaning. |
|

- intelligent recipe memory In order to guarantee an end product of consistent quality, the extruder system is equipped with an intelligent recipe memory. This offers two significant benefits: the susceptibility to process errors decreases, and production can be quickly adapted to other recipes. |

Screw Elements:
1. Supper anti-abrasive and anti-corrosion
2.. Raw material is heating treatment and overall hardening, high wear-resistance and toughness.
3. Special heat treatment and high precision CNC machining. Make sure to get the best quality.
- Suitable for your high protein materials
Different screw elements combination use for different function material compounding, Our lists of screw elements are including the following:
--Conveying elements

Extruder Barrel:
Extruder barrel is made with bushing and cylinder, bimetallic treatment.
The screw and barrel of double screw extruder machine adopt segmented design. Different combination of barrel decide the extruder L/D; different combination of screw decide the extruder function.
