“…Thus the total air flowrate is 29532 m 3 ·h -1 . If the efficiency from coal to electricity is 40%, compared with literature [2], the energy consumption of proposed system is only 28% of traditional system using coal as energy source. Table. 1 lists the operation parameters of 5 heat pump units which have very different operation conditions.…”

“…According to the work of DI Kun [3], the energy consumption for corn drying using coal reaches 7535~8370 kJ/kgH 2 O. Besides, during the combustion of coal, a large number of harmful gases like CO, SO 2 and NO x emit into the atmosphere, causing serious smog, acid rain, and toxic air pollution.…”

Abstract.A multi-stage series heat pump drying system with dehumidification is proposed to meet the demand of corn drying in Northeast China. The mathematical model of the system is developed in EES (Engineering Equation Solver). After building the model, the system's performance under stable conditions is simulated. The result shows that a 5-stage system has a dehumidification rate of 400 kg·h -1 and a SMER (specific moisture extraction rate) of 4 kg/kW·h. The primary air flowrate, air inlet temperature and air inlet relative humidity are the main parameters influencing the system performance. The dehumidification rate and SMER of the system have positive correlations with them. The air inlet temperature and air inlet relative humidity have more significant influence. An experiment of 4-stage system is conducted and the result is consistent with simulation. Currently, coal is the main energy source for drying corn in Northeast China, not only wasting a lot of energy, but also causing serious pollution. Compared with burning coal, the proposed system has great potential for energy saving and environmental protection.

Drying Mechanism of Unutilized Cedar Logs as a Source of Heating Fuel

-In Japan, small, forested areas are often destroyed because neglect due to a slump in wood prices and a shortage of labor. Promotion of forest maintenance along with the use of unused woody biomass is desired. In this study, the drying mechanism of Cedar (Cryptomeria japonica) logs destined to be used as heating was examined. The experimental results show that cedar samples reached the fiber saturation point after 4-5 months of drying on site. The water in the wood moved to the cut ends and evaporated because of the high pressure differences on the surfaces of the cut ends. The water content in the center of the logs was higher than that at the cut ends because closed pits in the vessel structures prevented the passage of water.

“…A number of drying methods have been employed and studied, such as air drying (Chua et al, 2001;Nguyen and Price 2007;Prachayawarakorn et al, 2008;Leite et al, 2007), microwave drying (Maskan 2000), osmotic dehydration (Krokida et al, 2000a;, and solar drying (Phoungchandang and Woods 2000); those studies have focused on modelling the drying process, or determining the effects of various parameters on the final product.…”

Traditionally prepared sun-dried bananas were evaluated for textural and rheological properties. Assessment of how those properties changed over a storage period of two months was also carried out. The texture analysis results that relate to large deformations of the product show that the samples were not significantly affected by storage for one month, but subsequent storage for an extra month did result in softer samples. Rheological characterisation shows that upon heating samples become more elastic, however, this behaviour was reversed upon cooling. The rheological behaviour did not change significantly over the two month storage period. Overall results indicate that textural changes are not the limiting factor in the shelf life of this product. Further work is recommended in order to improve our understanding and maximise the stability of the product over the anticipated shelf life.
