Case Studies
Real projects, real materials, real results
A selection of engineering projects showing how our equipment was specified and configured to solve a specific drying or mixing challenge.
Vacuum Rake Drying for an Oxidation-Sensitive Chemical Intermediate
Fine chemical intermediate paste, moderate solvent content
A specialty chemical producer needed to dry a paste-form intermediate that was prone to oxidation and discoloration when exposed to air at elevated temperature. Conventional oven drying produced inconsistent color and required a lengthy secondary solvent-recovery step, adding cost and processing time to each batch.
Low-Temperature Conical Vacuum Drying for a Pharmaceutical Intermediate
Heat-sensitive pharmaceutical intermediate powder
A pharmaceutical intermediate producer required a drying process that would not expose the product to temperatures that risked degrading its active content, while still achieving the residual moisture target needed for the next processing step. The customer also required a design compatible with cleaning and inspection procedures common in GMP-oriented environments.
Filter Cake Volume Reduction with a Hollow Blade Dryer
Industrial filter cake / sludge
An industrial facility needed to reduce the volume and weight of filter cake generated by its wastewater treatment process to lower disposal costs and transport frequency. The material had a variable moisture content and needed continuous processing to keep pace with the treatment line.
Converting a Liquid Extract to Powder with Centrifugal Spray Drying
Food-grade liquid extract
A food ingredient manufacturer wanted to convert a liquid extract into a stable, free-flowing powder suitable for packaging and long-term storage, without a separate crushing or screening step, and while limiting thermal exposure during the brief drying period.
Drying Pigment Filter Cake in a Vacuum Rake Dryer
Pigment filter cake, water-wet, paste consistency
Pigment filter cake arrives from the filter press as a dense, water-wet paste. Drying it in a tray oven drives surface water off quickly but leaves the cake case-hardened, so the last of the moisture has to diffuse through a crust and the batch takes far longer than the first hour suggests. Colour shift is the other risk: pigment pastes that sit on a hot surface discolour at the contact layer.
Continuous Plate Drying for a Solvent-Wet Chemical Powder
Solvent-wet granular chemical powder, free-flowing once dried
Granular chemical powder leaves the centrifuge wet with solvent, and the moisture has to come off without pushing the product past its temperature limit. A single-zone tray oven cannot do both jobs. The trays nearest the heat source dry first and keep taking heat while the rest of the batch is still wet, so one batch ends up over-dried and under-dried at the same time. Operators compensate by extending the cycle, which lengthens thermal exposure for the whole batch and raises the solvent load in the exhaust. Solvent recovery adds a second constraint: the drying chamber has to stay closed and the vapour has to leave through one controlled outlet instead of an open door.
