Research ArticleOpen accessIn the author namesCassava Chip Drying by Using a Small-Scale Hot-Air Microwave OvenPatomsok WilaiponCharacteristics of cassava microwave hot-air drying were investigated in a 2-planes microwave hot-air dryer. The drying experiments were carried out at two levels of sample surface temperature set-points viz. 70 and 80°C respectively. Cassava (Rayong-9) with 2.5 kg weight and 61% moisture content on wet basis was dried in the dryer for about 5-5.3 h. It was found that the … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 2 · 6 Jun 2013 · 7,573 accessesView PDFCite
Research ArticleOpen accessIn the author namesDurian Husk Properties and its Heating Value EquationPatomsok WilaiponProblem statement: Agricultural residue seems to be one of the most promising energy resources for developing countries. Among the other fruits, durian is a popular one for Thai people. Therefore, a large amount of durian husk is left at the shops or factories. This study was aimed to investigate the characteristics and heating value of durian husk and to develop … …American Journal of Applied Sciences, Vol. 8, Issue 9 · 1 Aug 2011 · 7,865 accessesView PDFCite
Research ArticleOpen accessIn the author namesDensity Equation of Cassava-Stalk Briquettes Under Moderate Die-PressurePatomsok WilaiponProblem statement: Agricultural residues seem to be the most promising energy resources for developing countries. However, the majority of them have low energy density. One of the favorable technologies for enhancing that property is briquetting. For the case of Phitsanulok, a province in Northern Thailand, cassava is one of the most important crops. Therefore, a large amount of cassava stalk … …American Journal of Applied Sciences, Vol. 7, Issue 5 · 31 May 2010 · 7,288 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Effects of Briquetting Pressure on Banana-Peel Briquette and the Banana Waste in Northern ThailandPatomsok WilaiponBanana is considered as one of the most important agricultural products of Northern Thailand. A large amount of banana peel has been left as garbage after industrial processes. The raw material is plentiful and has low economic value. Therefore, the characteristics of banana-peel briquettes including banana peel properties were investigated. The briquettes were produced with pressures ranging from 3 to … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 11,915 accessesView PDFCite
Research ArticleOpen accessIn the author namesDensity Equation of Bio-Coal Briquettes and Quantity of Maize Cob in Phitsanulok, ThailandPatomsok WilaiponOne of the most important crops in Phitsanulok, a province in Northern Thailand, is maize. Base on the calculation, the quantity of maize cob produced in this region was approximately 220 kton year-1. The net heating value of maize cob was found to be 14.2 MJ kg-1. Therefore, the total energy over 874 TJ year-1 can be obtained from this … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,896 accessesView PDFCite
Research ArticleOpen accessIn the author namesPhysical Characteristics of Maize Cob Briquette under Moderate Die PressurePatomsok WilaiponThe potential energy content of maize cob available in Thailand was calculated based on maize productivity, the residue-to-product ratio and the heating value of maize cob. It was found that the computed value was about 74.2 PJ/year. Besides, the potential energy value exceed 1,000 TJ/year was also reported for the case of five provinces of Thailand. Concerning with maize cob … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 8,091 accessesView PDFCite
