Effect of Air Drying, Solar-Assisted Air Drying and Sticker Thickness on Mahogany (Khaya senegalensis) Wood

For Khaya Senegalensis ( Australian Mahogany ) Bark Extract

The bitter tasting bark is used for a variety of medical purposes. An extract of the bark of Khaya senegalensis is commonly used in African traditional medicine for pain and inflammation, against fever caused by malaria, stomach complaints and headaches. It is widely used in the treatment of fever, malaria, to cure skin rashes, wounds, mucous diarrhea, as an anti-microbial agent in venereal dis...

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...

Ultrasound-Assisted Vacuum Drying of Wood: Effects on Drying Time and Product Quality

Ultrasonic energy was applied to assist the wood vacuum drying process. At a drying temperature of 60°C, the absolute pressure was either 0.05 MPa or 0.08 MPa; the ultrasonic power and frequency were 100 W and 28 kHz, respectively. The results showed that the effective water diffusivity of the specimens dried by the ultrasonic assisted vacuum drying at 0.05 MPa or 0.08 MPa were higher than that...

Comparative study of three drying methods: freeze, hot air- assisted freeze and infrared-assisted freeze modes

The dehydration tests were conducted at three drying methods to evaluate the drying curves and the energy uptake. Apple (Malus domestica L.) cubes were dried under different processing conditions applying freeze drying (FD), freeze drying assisted by hot air and freeze drying assisted by infrared radiation. Control samples were produced using regular freeze drying without the pre-drying. Hot ai...
