CalAg LLC commissioned Siempelkamp with the supply of a production plant for fiberboard made of rice straw.
CalAg LCC is investing more than $315 million for the new location in Willows, California. This order requests Siempelkamp’s complete range of services. From a single source Siempelkamp will plan, build, supply, install, and startup the entire machine technology for the Willows location amounting to an order value of Euro 75 million.
The order includes the complete preparation technology for rice straw bales with bale twine remover and shredder by Pallmann, a 100 % daughter company of Siempelkamp, as well as a cleaning system for the straw to remove coarse materials and dust.
Pallmann also supplies two refiners for the fiberizing of the rice straw. These refiners are equipped with horizontal digesters, a design typical for annual plants, to prevent material bridging. The cleaning system for separating silicate components from the fibers is a design specially developed by Siempelkamp and designed to process rice straw.
The natural gas fiber dryer designed for a material throughput of up to 32 metric tons/h bone-dry is supplied by Siempelkamp’s subsidiary Büttner.
The core component of the future production plant for rice straw fiberboards will be a 9th Generation ContiRoll ® press with its numerous innovations including, for example, the highly efficient drive motor ContiRoll Ecodrive.
With the new Siempelkamp plant, CalAg will produce 200,000 cubic metres of fiberboards annually following the startup of the plant scheduled for the end of 2018.
