Quality assessment of the drying process for Eucalyptus delegatensis timber using greenhouse solar drying technology

Solar Drying Technology for Food Preservation

Food losses in the developing world are thought to be 50% of the fruits and vegetables grown and 25% of harvested food grain (Burden, 1989). Food preservation can reduce wastage of a harvest surplus, allow storage for food shortages, and in some cases facilitate export to high-value markets. Drying is one of the oldest methods of food preservation. Drying makes produce lighter, smaller, and les...

Microwave Preconditioning to Accelerate Solar Drying of Timber

Wood drying is essential for preparation of this natural resource for practical applications. Solar drying can reduce drying costs and energy consumption. There are many potential models to describe the drying process. However, most models confirm that the tortuosity of the moisture transport path is an important control parameter during the diffusion-controlled drying process. Microwave heatin...

Temperature Control in the Technology Process Drying

There is described a control system for the new technology in this paper. That technology, makes it possible to process chromium tannery wastes with the help of enzymatic hydrolysis and was created at the Department of Automatic Control Faculty of Technology UTB in Zlín. The enzymatic hydrolysis process is composed from three parts: fermentation, filtration and drying. In this paper there are d...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
