Product Details:

The extrusion portion of the system includes a live bin/feeder, extrusion cooker, and die / knife assembly. The design of each of these components is engineered to accomplish a specific function in the process of extruded rice. Within the design features, the operating conditions are adjusted to vary the properties of the finished product.
A. Live-bottom holding bin / feederThe live bin/feeder provides a means of uniformly metering the raw materials (typically floury in nature) into the preconditioner and subsequently into the extruder. This flow of raw material must be uninterrupted and rate controllable. The live bin/feeder controls the product rate or throughput of the entire system. The live bin/feeder system can be controlled in a volumetric or gravimetric manner. In a volumetric setup, the feeder delivers a constant volume of feed to the preconditioner. When operating under gravimetric, or loss-inweight (LIW), conditions the feeder delivers a set mass flow rate of raw material to the preconditioner.
B. ExtruderExtruders used for the manufacture of extruded rice are twin screw in design. The impact on final product characteristics such as texture, rehydration, density, etc. is produced by screw and barrel profile, screw speed, processing conditions (temperature, moisture, retention time), raw material characteristics and die selection.
The initial section of the extruder barrel is designed to act as a feeding or metering zone to simply convey the preconditioned rice away from the inlet zone of the barrel and into the extruder. The material then enters a processing zone where the amorphous, free flowing rice flour is worked into a colloidal dough. The compression ratio of the screw profile is increased in this stage to assist in blending water or steam with the raw material. The temperature of the moist dough is increased slightly though the addition of mechanical energy via the extruder screws. The temperature rise in the extruder barrel is from mechanical energy dissipated through the rotating screw.C. DieThe extrusion chamber must be capped with a die apparatus. The die offers restriction to product flow and shapes the extrudate. Dies for extruded rice are typically face dies. The die is fitted with a variable speed cutting device to size the kernel.D.
