Manufacturing a pure product can be critically important to the next steps in the manufacture of a powder-based product. As a result the removal of residual moisture and solvents from the crystallization, filtration and drying steps can be crucial to producing a stable product.
This application note describes two technology solutionscontinuous weight information using loadcell systems or level information using ultrasonic systemsto the problems faced by day bins supplying downstream operations.
In this article, Kumar Dhanasekharan, Ph.D., technical specialist with the computational fluid dynamics (CFD) specialist Fluent, Inc., shows how modelling crystallizers using CFD can help improve process understanding, control crystal size distribution (CSD) and improve pharmaceutical crystallization results.
Capacitance-type magnetic flowmeters have traditionally offered the advantage of having non-wetted electrodes and the ability to measure low conductivity fluids. However, they suffered from a sensitivity to flow noise and zero instability. Innovative technology overcomes these limitations and drives magnetic flowmeters into new areas of application, while reducing installed costs.
Specifying a hygienic bulk solids feeder is not a simple task. The wide variety of requirements needed
for specific applications are similar in scope to explosion proof environmental requirement variations.
Fine powders present problems that bulk solids do not when they are contained in a bin, hopper or processing vessel. The primary problem is the powder's flow pattern. This 10-page PDF whitepaper discusses solutions to this problem.
This 26-page white paper from Monitor Technologies discusses the difficulties in measuring bulk solids and powders in bins, silos and hoppers. Download this document to learn which technologies are out there that can make this job easier.
This white paper from Delta Controls outlines a range of selection and installation criteria for using admittance probes to monitor the level of powders, liquids and other materials. Dielectric constants of more than 200 common industrial materials are included.
