Using Superheated Steam in Drying and Sterilization

Botanicals are received in whole, non-sterile form. BI Nutraceuticals sterilizes, mills, and packages the ingredient in sturdy, safe containers before shipping to customers. Photo courtesy of BI Nutraceuticals Using Superheated Steam in Drying and Sterilization It seems counterintuitive to use water vapor in a process to remove water or to heat materials that can be damaged by moisture, but suc...

Superheated Steam Drying at Atmospheric Pressure

A MEMS Steam Generator

Previous work [1] has shown that MEMS technology has significant potential to create more compact, higherperforming hardware for chemical oxygen iodine lasers (COIL). In COILs, the laser medium is a flowing gas that must be pumped through the system at high mass flow rates to ensure proper system operation. As a result, compact pumps with high pumping rates are a key element of the COIL system....

Cascade control of superheated steam temperature with neuro-PID controller.

In this paper, an improved cascade control methodology for superheated processes is developed, in which the primary PID controller is implemented by neural networks trained by minimizing error entropy criterion. The entropy of the tracking error can be estimated recursively by utilizing receding horizon window technique. The measurable disturbances in superheated processes are input to the neur...

Modelling the Drying of Porous Coal Particles in Superheated Steam

The modelling and simulation of drying porous coal particles in superheated steam was investigated in this paper. Improved transport and kinetic parameters as well as particle shrinkage were considered in arriving at the results. The resulting partial differential equation describing the drying process was solved numerically using the finite element analysis in addition to other useful equation...
