Speed Control in Microwave Drying Of Apple

2010 Pittsburgh, Pennsylvania, June 20 - June 23, 2010, 2010
Microwave drying of apple at constant temperatures of 50 – 80 °C follows typical drying curves. The middle stage of the drying process shows a faster drying speed and accelerated moisture evaporation. Meanwhile, more flavors are lost, surface color is degraded, and charring often occurs.

High Speed 3D Milling by Dry EDM

CIRP Annals, 2003
Abstract This paper describes the high speed EDM milling of 3D cavities using gas as the working fluid. In this new process, the molten workpiece material is removed and flushed out of the working gap with the help of high-pressure gas flow. The advantages or this technique are the remarkably small tool electrode wear and the significantly high ...

High-speed dry compound machining of Ti6Al4V

Journal of Materials Processing Technology, 2015
Abstract Milling experiments on Ti6Al4V using high-speed compound machining with high-speed air dielectric were conducted in this study. The new and efficient compound machining combines arc machining and electrical discharge machining (EDM) together, both of them are working in parallel. Ti6Al4V can be quickly melted by significantly high processing

EFFECT OF DRYING SPEED ON THE DESATURATION OF SWELLING ROCK [PDF]

GEO-EXPO
The paper presents the results of a numerical study of the influence of drying speed and hydraulic conductivity of swelling rock on the development of the desaturated zone. Swelling rock refers to natural material in which montmorillonite is the predominant type of mineral.

Camera Speed Dry Silver Film.

1978
Abstract : In order to increase the photosensitivity of Dry Silver, knowledge of both the photosensitive and the thermographic aspect of Dry Silver had to be advanced. In order to increase the photosensitivity, silver halide crystals had to be prepared which were more prone to photolytic reduction.

Speed of crack propagation in dry aqueous foam

EPL (Europhysics Letters), 2010
Applying pressure driving to a single layer of aqueous foam bubbles induces a void propagation that is a surprisingly close analog of dynamic crack propagation. Depending on the rate of applied stress, both a ductile and a brittle mode of propagation are observed, the latter at much higher propagation speeds.

Speed effects on the dry and lubricated wear of polymers

Wear, 1986
Abstract The influence of speed on the friction and wear of polyphenylene oxide (PPO), polyetheretherketone (PEEK) and polytetrafluoroethylene (PTFE) has been determined in two sliding configurations under both dry and lubricated conditions. With a line-contact geometry, the effects of debris aggregation on wear play a more important role than with a

High-speed dry electrical discharge machining

International Journal of Machine Tools and Manufacture, 2015
Abstract A novel high-speed dry electrical discharge machining (EDM) method was proposed in this study. Using this method, the material can be rapidly melted by extremely high discharge energy and flushed out of the discharge gap by high-pressure and high-speed air flow.
