Modern Freeze Drying Design for More Efficient Processes

Dear Colleagues,

Chemical process design, simulation, and optimization constitute the core of the activity of chemical process engineers, process developers and designers, process economic evaluators, energy engineers and researchers implicated in chemical engineering.

The aim of this Special Issue is to collect the actual knowledge on the freeze-drying process in food and pharmaceutical downstream processing as well as in new fields of applications. Both experimental and modelling approaches to design a more efficient freeze-drying process are accepted.

The paths to a more efficient freeze-drying process include controlling ice nucleation by a designed freezing process, a better in situ measurement technology for endpoint detection, and a better freeze dryer design such as rotating drums or novel heating technologies such as microwaves. New technologies like spray freeze-drying, modelling the sublimation process on a pore scale level, and new methods for in situ observations of the freeze-drying process are welcomed.

Topics include, but are not limited to, applications in the following areas:

• Novel processes (especially spray freeze drying, combined drying processes)
• Novel Equipment (rotating drums, microwave heating)
• Modelling of freeze drying including pore scale modelling of freeze drying process
• Controlling freezing for defined microstructure
• Impact of pore structure on freeze drying process including collapse
• Measurement technology for endpoint detection including design space
• Novel imaging methods for in situ observation of freezing and the freeze-drying process.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the Special Issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Processes is an international peer-reviewed open access semimonthly journal published by MDPI.
