Description
As part of our full systems’ line – ABC Hansen has developed a full fat soy bean extrusion line, with capacities between 500kg and 1000kg/hr
The plant flow is as follows:
-Soy beans are received into a triangular reception bin Reception bin – Triangular – 3m
-The soy beans are then conveyed to a Quaill eccentric cleaner (Cleaner eccentric – Quaill I. 0.5-1.5T) via an auger (Augers 165mm).
-From the cleaner the soy beans are conveyed to the destoner (Destoner) to remove stones and heavier material, and to also aspirate the product before milling.
-The cleaned soy beans are then fed into a Hippo Hammer mill, either a Size 1 (Hippo Hammer Mill Size 1) or a size 47 (Hippo Hammer Mill Size 47) depending on capacity of the plant – to mill down the soy beans to a size that the extruder is able to handle – usually particle sizes no larger than 3mm each.
-The hammer mill then mills the soy beans down, and blows them directly into a buffer silo (Hopper bin – 1.2m³) with a capacity of 1200liters. The buffer bin is fitted with a vibration motor, to prevent bridging in the silo when unloading.
– The hopper bin is unloaded by speed controlled augers – fitted with variable speed drives (Variable Frequency Drive (VFD)) into the extruders.
– The extruders (Extruder) then receive the milled soy beans, and extrude them, by forcing them into a confined space with a screw mechanism, thereby creating high pressure and high pressure in the extrusion chamber, resulting in the breakdown of the trypsin inhibitors in the soy beans – improving the digestibility of the product, resulting in what is known as full fat soy (FFS)
– The extruder then discharges the extruded soy beans into a vented screw conveyor with a 12m length fitted with a 1,1KW blower (Blowers & Fans), where an initial cooling happens as well as most of the steam being removed from the product, before being introduced to the cooler.
– The vented trough auger then discharges to the Pellet cooler and grader, where the extruded full fat soy is then cooled to ambient temperature, before being discharged to further processing, or to bagging/storage.
All processes are controlled from an included Motor control centre
