Pilot Plant Testing Leads to Better Results from a Fluid Bed Dryer

Posted by H&P Blog on Wed, Jul 08, 2015 @ 09:46 AM

A pilot plant is a small-scale industrial plant in which problems can be identified and solved before the corresponding full-scale facility is built. In terms of thermal processing, such a testing ground is a basic laboratory that uses stock process equipment to provide valuable data for the design of a larger version, so that any anomalies in the process can be worked out before the full-scale plant is constructed. Scientific data about reactions, material properties and even corrosiveness may be gathered, and it helps to predict the behavior of a process. Plant designers use data from the pilot facility to refine their design of the production scale facility. When bulk materials must be dried as a part of the process, a fluid bed dryer is often a key component.

Rotary Dryers: Direct Drying vs. Indirect Drying

Posted by H&P Blog on Wed, Dec 28, 2011 @ 09:22 AM

One of the most important factors in determining what type of Rotary Dryer is right for a certain process is the usage of direct or indirect heat.  Rotary Dryers are capable of utilizing either direct convection style heat transfer or indirect heat transfer, in which hot surfaces within the dryer provide heat by conduction and radiation.  The determination of direct or indirect drying is contingent on the properties of the material to be dried, the process conditions and the desired end product.

Determining Specifications for a Rotary Dryer

Posted by H&P Blog on Wed, Dec 21, 2011 @ 11:00 AM

Rotary Dryers are the most versatile dryers available.  For continuous drying of bulk solids, they excel in their ability to handle a very broad range of materials regardless of their conveying and handling characteristics.  Whether a process requires the drying of fine dusty powders, lumpy solids, sticky semi-plastics, pellets, agglomerates or even a mixture of all of those, there is a Rotary Dryer that will accomplish the task successfully.

Wood Torrefaction to be a Hot Topic at Northeast Biomass

Posted by H&P Blog on Wed, Sep 14, 2011 @ 09:03 AM

One of the latest biomass techniques in use today is torrefaction, a thermochemical treatment of wood biomass at 500-600° F (260-320° C) which is carried out under certain atmospheric conditions without oxygen.  During the process, the wood's internal water and low boiling-point organics are removed, and the cellulose, hemicellulose and lignin partially decompose and give off various types of volatiles. The final product is a dry, blackened material referred to as "torrefied biomass" or "bio-coal."
