Drying Energy Efficiency Through Partial Air-Drying: A Case Study

The green lumber products tend towards a state of equilibrium with the surrounding environment. The final target is the equilibrium moisture content (EMC). Whether is natural convection in the lumberyard or forced convection in the kiln drier, the road towards the final EMC consumes time and energy. The air drying operations (natural convection) are not an easy task for the drying management. T...

Anciently asexual bdelloid rotifers escape lethal fungal parasites by drying up and blowing away.

Asexuality has major theoretical advantages over sexual reproduction. An important evolutionary puzzle, therefore, is why exclusively asexual metazoan lineages rarely endure. The Red Queen hypothesis posits that asexuality is rapidly extinguished by relentlessly coevolving parasites and pathogens. If so, any long-lasting asexual lineage must have unusual alternative mechanisms to deal with thes...

Drying kinetics and mathematical modeling of hot air drying of coconut coir pith

Drying kinetics of coir pith was studied and the properties of compressed coir pith discs were analyzed. Coir pith particles were oven dried in the range of temperatures from 100 to 240 °C and the rehydration ability of compressed coir pith was evaluated by finding the volume expansion. The optimum drying temperature was found to be 140 °C. Hot air drying was carried out to examine the drying k...

Foot-and-mouth disease virus: stability of neutralizing antibody after freeze-drying and air-drying.

It is possible to stabilize foot-and-mouth disease antiserum by either freeze-drying in bottles or air-drying on paper for periods of 7 months.
