Primary Driving Force in Wood Vacuum Drying
… is the primary driving force during the vacuum drying. The theoretical drying rates of diffusion, free water bulk flow and water vapor bulk flow were calculated and compared. The concept of equilibrium moisture content under the vacuum was developed. The theoretical maximum moisture …

The Impact of Vacuum-Drying on Efficiency of Hardwood Products Manufacturing
… like lean manufacturing. However, the lumber drying process where lumber is kiln-dried in large batches, can significantly increase manufacturing and inventory lead-time; and is a process that tends to limit how lean the remaining process can become. Vacuum drying has the potential to reduce …

Thermal Behavior of the TN-32B Spent Nuclear Fuel Cask under Storage and Vacuum Drying Conditions
… in a spent fuel cask under storage and vacuum drying conditions. In particular, the TN-32 spent nuclear fuel cask was modeled because it is one of the few demonstration casks with publicly available experimental data to validate computational models for storage and vacuum drying …

Process-morphology-property Relationships in Strut-like Poly(ether ether ketone) Aerogels Prepared through Thermally Induced Phase Separation
… resist the forces imposed on the gel during drying. Monolithic strut-like PEEK or PPS aerogels were prepared with vacuum-drying, freeze-drying, and supercritical CO2 extraction with minimal shrinkage and deformation. The weaker globular PEEK aerogel morphologies suffered from considerable …

Solvatochromic pyrogallarenes and pyrogallarene crystals
… 1 possessed a visible chromophore, but upon vacuum drying the color was quenched. PXRD of the colorless solid proved that vacuum drying resulted in removal of solvent molecules in the crystal structure, a hallmark of solvatochromism. Titration of C-propyl pyrogallol[4]arene over the entire pH …

Untersuchungen zur Gefriertrocknung biologischer Zellen am Beispiel menschlicher Erythrozyten
Freeze-drying is a state of the art process for stabilization of pharmaceutical or biotechnological products. However, a successful preservation of living cells by freeze-drying is still a big challenge. This is mainly due to increased requirements on the product quality, since even smallest …

Adhesion Fundamentals in Spotted Gum (Corymbia citriodora)
… Gympie messmate. This suggests conventional kiln drying appears unsuitable for spotted gum while amenable for Gympie messmate. Spotted gum likely requires non-aqueous, low surface tension adhesives or aqueous adhesives formulated with surface active wetting agents. Water-saturation (followed by …

Design and automated operation of a condensation-induced depressurization system
Typical examples of the use of the vacuum environments in industry include vacuum coating, vacuum drying, vacuum packing, vacuum casting, vacuum heat treatment, vacuum cooling for food storage and leakage detection. Most of these applications require a comparatively small volume of vacuum …

CHICKPEA AQUAFABA AS AN EMULSIFIER IN FOOD-OIL SYSTEMS
… of optimum conditions for preparing AQ, five drying methods (freeze drying, spray drying, oven drying, rotary evaporation drying, and vacuum drying) were compared. Dried AQ was rehydrated with distilled water, and its emulsion capacity and stability were measured. AQ from CDC Leader had the …

Investigation of drying conditions for dental practice loads
This thesis investigates different drying techniques for dental practice loads experimentally and numerically. Several experiments are carried out by changing both top and bottom wall temperatures while changing the ranges of the pressure pulses during the drying phase. The studies show that both …

Präadipozyten auf neuartigen Textilmatrizes
… by a surface cleaning procedure followed by vacuum drying and gamma sterilisation. Preadipocytes were isolated out of human subcutaneous adipose tissue of healthy patients who had undergone elective operations. After the isolation procedure, preadipocytes were cultivated in culture dishes and …

Fabrication of tissue engineering scaffolds with spatial control over architecture and cell-matrix interactions in 3D
… of chloroform (-5 wt%) after conventional vacuum drying. Liquid C02 extraction was demonstrated to be capable of reducing chloroform in these devices to levels below 50 ppm. Drying was modeled as a diffusion process and diffusion coefficients were estimated for both a batch and a …

Rational Design of Poly(phenylene sulfide) Aerogels Through Precision Processing
… manufacturing), dissolution temperature, and drying method. The ultimate goal was to elucidate key process-morphology-property relationships in PPS aerogels, to ultimately improve aerogel performance and applicability. The phase diagram of PPS/DPA was first elucidated to determine the phase …

Prozessorientierte Untersuchungen zur Schmierstoffsynthese basierend auf Ölsäuremethylester und Glycerintrioleat
… catalyst cleaning process using scCO2 and vacuum drying afterwards the catalyst could be recycled at least three times in reaction without any remarkable losses in selectivity and conversion. But with recycling the catalyst it starts to leach H2SO4 and aryl-sulphuric acid groups in the …

Layered graphene nanomaterials for gas separation membrane applications
… the completely stacked graphene-oxide chain by vacuum-drying, heating, or partial reduction of the graphene-oxide. The effect of moisture content in the structural integrity of the membrane is also realized with several controlled drying approaches of the ultra-thin membranes. Finally, the …

Investigating casein-polymer interactions as a platform technology for cheese for Asian consumers
… Cheese puffs (manufactured using microwave vacuum drying: MVD) produced from Cheddar curds with or without polysaccharide addition at dry salting were characterised. MVD was shown to be a promising technology to produce dried cheese snacks with minimal changes in properties such as colour …
