The aim of this study was to develop a freeze-drying protocol facilitating successful processing of plant material containing the small surface antigen of hepatitis B virus (S-HBsAg) while preserving its VLP structure and immunogenicity. Freeze-drying of the antigen in lettuce leaf tissue, without any isolation or purification step, was investigated. Each process step was consecutively evaluate...

Superheated steam drying technique has been known for a long time, but its application to food drying has received little attention. In this work, superheated steam was applied to dry fresh parsley (Petroselinum Cripsum). A mathematical model to simulate this drying process was developed by using mass and energy conservation equations for solid and steam phases. The resulting partial differenti...

In this paper, the results of an experimental study on textile thermal drying after wet processing pretreatments are presented. The mass variation of the studied samples as a function of drying time was determined using the gravimetric method at three different temperatures: 100°C, 110°C and 120°C. A polynomial model was found and established to follow the drying phenomenon of wet textile fabri...

The nickel(ii)–chloranilato complex shows reversible vapochromism with changes in dimensionality upon exposure to various vapours and subsequent drying by heating.

Drying is a common pharmaceutical process, whose potential to modify the final drug and/or dosage form properties is often underestimated. In the present study, pellets consisting of the matrix former calcium stearate (CaSt) incorporating the active pharmaceutical ingredient ibuprofen were prepared via wet extrusion and spheronization. Subsequent drying was performed by either desiccation, flui...

The paper describes the detailed techno-commercial analysis done on a 46 m2 solar air heating system developed in a food processing industry. The solar air heating system was connected to an indoor drier through a duct. A detailed performance analysis was undertaken on the system by loading with 75 kg of ripe mango flake. The product loaded was uniform in size having a thickness of 4mm. On a cl...
