Process of soybean extruder

Soybean extruder is the main technological equipment for rice bran stabilizing treatment and bean extruding in cereal and oil industry, and also can be used to manufacture different expanded feeds in oil mills, rice mills, and soybean protein factories and feed mills.
This extruder is composed of a driving system, a feeding device, an extruding device, an electric control cabinet and so on
The working principle of the extruder is to transfer mechanical energy to thermal energy by extrusion, friction and shearing function of non-equidistance screw extrusion system, and form a certain pressure and temperature in the extruding chamber, so material is sprayed out from the discharging die head to be expanded and formed.
Crude oil manufactured by extruding and extracting technology is of light color and low acid value, it is easy to make advanced cooking oil in different levels; and bulk weight of material increases after being expanded, so that production capacity of extruder can be greatly improved and residual oil rate of dry cakes is lower than 1%. Raw material is naturally heated to about 110℃ after entering the soybean extruder, and then sprayed out through die head (that is to say it is expanded and formed). During the extruding process, temperature of mechanical friction heat can inhibit activity of active teichomycin and can kill some fungi and microorganism, so that material will not deteriorate in a longer period.
Before using the extruder, the soybean also can be cleaned, grinded, flaked etc, which used to improve the capacity of the machine and reduce the toxin in the final product.
This extruder should be installed on a flat foundation, it is better to install foundation screw, and a proper space around it should be remained in convenience for discharging, conveying and packing, and a certain space shall be remained for easy removal and maintenance. Incoming line of electric control cabinet shall be reasonably equipped based on motor power. Installation of connector of speed control gauge: align connector keyways with protuberant rib, insert the connector, and then tighten the fastening helicoids.
