Title: Innovations by David Debo in Freeze Drying Technology
Introduction
David Debo is an accomplished inventor based in Batavia, NY (US). He has made significant contributions to the field of freeze drying technology, holding 2 patents that showcase his innovative approaches to processing aseptic bulk powder products.
Latest Patents
One of his latest patents is titled "Bulk freeze drying using spray freezing and agitated drying with dielectric heating." This invention describes a freeze dryer that processes aseptic bulk powder products by mixing an atomized spray of the product with sterile liquid nitrogen to produce a frozen powder. The frozen powder is then freeze dried in a vessel by dielectrically heating it using electromagnetic radiation, such as microwave or infrared radiation. Continuous agitation is maintained using a sterilizable apparatus, such as a series of vibrating shelves, to ensure even heating and prevent agglomeration.
Another notable patent is "Monitoring freeze drying with gas measurement on vacuum pump exhaust." This patent outlines a method for monitoring parameters of the freeze drying process by measuring trace materials in the vacuum pump exhaust. Techniques such as acousto-optic spectrometry, multipass cavity-enhanced absorption spectrometry (CEAS), and cavity ring-down spectrometry (CRDS) are employed to diagnose potential issues, such as leakage in the freeze drying shelves and condensation coils. This technique also aids in monitoring the presence of water vapor during the secondary drying process.
