STHT Processor
Description of the STHT processor:

- Expander is a machine similar to an extruder, combining temperature and pressure to treat and condition raw materials to provide a crumb with improved nutritional value to that of conventional feeds.
- Expander is supplied with:
• drive/power transmission
• charging hopper
• screw for compression and homogenizing
• independent head section with fully adjustable flat die arrangement
• multiblade, variable speed knife arrangement cuts the material into uniform crumb
- Main drive has a hydraulic coupling, with built in torque overload and v-belt drive transfer
- The heavy duty compression screw is constructed out of several sections on a single shaft, increasing shear action
- The die assembly can be hydraulically turned/disconnected from the machine for easy access
- The die aperture is hydraulically controlled allowing operator to increase/reduce compression/shear action and the extrusion/molding of final product remotely
- Variable speed knife arrangement, with independent drive, to determine crumb size and ensures uniform product size
- Through the length of the expander we can add steam under high pressure. It’s possible due to many special injectors
- Numerous injection points allow high-pressure steam, and additional liquids, to be added along the length of the expander
- Automatic control - allows operator to preset parameters and system can fine tune accordingly
- Flexibility due to the number of inlet points and short build up time allows system to stop/start without problems.
