Operation of Soybean and Powdery Extrusion

Even Muyang's extruder can solve all your matters, but you should still know what should be done when you face different materials in extruding. Generally, you may choose two materials with both soybean and powdery feed. Following is two ways for extruding:

Operation of soybean extrusion

Main process: preheat → install discharging chamber → adjust discharging screw plug → start the main motor → install the protective hood (without water add device → start feed motor, set the feeding frequency at about 10~12HZ, raise the feed rate gradually after the main motor current is decreased to ensure the stable and continuous producing.

Explanation:
——Screw down the screw plug by use of special wrench, loosen back for 3~4 circles;
——Screw down the screw upper the discharging chamber, fix the discharging screw plug;
——Start the main motor and feeding device of the extruding machine, increase feeding gradually, then install the protective hood;
——Replace the screw plug with different aperture(Φ 8, Φ 10) and adjust the position of discharging screw plug so as to get the different soybean flour output;
——The operation above mentioned should be done quickly to ensure the preheat effect.



Main controls parameters under normal running (for reference)
Current of main motor 95~100A
Temperature at the discharging part 125~135℃

Operation of powdery feed extrusion

Main process: preheat → install cutting device → start main motor → start feeding device → start cutting device → adjust feeding device to normal operation state → install protective hood

Explanation:
——Fix the machine frame to avoid forward and backward movement after install the cutting device;
——Install different die and adjust cutting speed to get the material in different length and size;
——The add water volume can be set before Preheat.

Main controls parameters under normal running (for reference)
Current of main motor 90~100A
Temperature at the discharging part 110~125℃
Water pressure (select) 0.20~0.35Mpa

It is necessary to know how to operate the extruding machines, and it is also important to manage how to operate for shutdown. Close the water inlet valve first and stop feeding, and then stop the cutting device and principal machine. Remove the discharging device immediately after shutdown, clean the discharging device, after that restart the main motor, add a certain amount of soybean flour to clean away the rest material in the extruding chamber and lubricate it, so as to facilitate the next startup.

Muyang Brand MY 90×2S Twin-Screw Extruder

MY90×2S Type Twin-Screw Extruder is mainly applicable for production of floating aqua feed, sinking aqua feed, expanded rich noodle and expanded foods.

The extrusion provides for production of many products with great superiority in comparison with other technologies. Because it integrates functions of different equipments in a single process when extruding in most cases, the procedures of mixing, extruding, cutting, cooking, forming and drying process in a certain degree can be carried out at the same time.

In comparison with single screw one, twin screw extruder has a great superiority in a series of performance indexes such as curing degree of product, pellet uniformity, pellet surface roughness, ingredient scopes applicable for processing and so on.

Special assembly screw structure is applied, so that various products can be produced if only simply changing screw arrangement or changing manufacturing and processing parameters. Other technologies are difficult to or can hardly produce products and products in certain shapes which were produced by this extruding operation.

This extruding machine operation is extremely effective for high-temperature and short-period processing, it is provided with a better nutrition improvement while effectively reducing different anti-nutritional factor s in products and sterilizing. The cooking process of this extruding operation can cure material in a great degree, sufficiently use steam and reduce power consumption, and thus process cost can be saved. Flow and flow ratio of all materials can accurately controlled by an auto control system, and different processing parameters can be recorded, so as to provide a basis for future production or adjustment of processing parameters.

This extruding machinery operation can effectively avoid industrial wastewater; this is an outstanding advantage for feed manufacturers bearing the increasing pressure for reducing influences of production activities on surrounding environment.
