Drying

Both a heat pump and solar dryer were designed and manufactured. They were experimentally analyzed by drying apples, and a comparison was made between the two. Apples were sliced 4 mm thick, and dried from 4.8 (g water/g dry matter) moisture content to 0.18 (g water/g dry matter) at 3.3 kg/m2s–2.4 k

There are a great many drying processes and types of equipment, such as dryers with immersed channels; the main advantage of this type of dryer, and the reason why it is chosen by manufacturers, is the homogeneous distribution of the drying air, made possible by dihedrons. In our work, we have inves

The AQUASOL-Enhanced Zero Discharge Seawater Desalination using Hybrid Solar Technology (EVK1CT2001-00102) project is one more attempt at using solar energy for water desalination, improving the economics and the environmental performance of a MED desalination plant. Within the project, an advanced

The management of residual sludge is an important subject. New environmental laws require the elimination of this waste by only two ways: incineration and agricultural use. In order to reach this goal, mechanical dewatering can be used as a first step due to its low energy cost. However, the final m
