Review Article FOOD SECURITY: SOLAR DRYERS AND EFFECTIVE

The review identified that drying methods affect sensory characters and nutritive attributes of dried products For nutrient preservation of dried products and superior drying speed the indirect forced convection type solar dryers are preferred but power requirement increase the cost of drying as well as limit their use in the rural areas Natural-circulation type solar tunnel dryers wind

drying methods (Chen 2003) Some common secondary methods rely on the electrical characteristics of the grain such as capacitance and conductance Near-infrared spec-troscopy can also be used but is generally more expensive although it can also measure compositional parameters The need for a low-cost moisture meter in developing countries has been advocated for several years to help

Sludge Drying Bed

Sludge drying bed (SDB) is the most widely used method for sludge dewatering Sludge drying involves natural ways of drying to mechanical ways of removing water content SDB is generally used for small and medium sized communities (TCHOBANOGLOUS et al 2003) The selection of the technology will depend upon land availability climatic factors the quantity and composition of the sludge

Development of Stable Lyophilized Protein Drug Products

Freeze drying or lyophilization is widely used for biopharmaceuticals to improve the long term storage stability of labile molecules This review examines general theory and practice of rational lyophilization of biopharmaceuticals Formulation development involving the selection of appropriate excipients their associated physical properties and mechanism of action in achieving a stable

Framing access to medicines in developing countries: an

In September 2003 the Canadian government committed to developing legislation that would facilitate greater access to affordable medicines for developing countries Over the course of eight months the legislation now known as Canada's Access to Medicines Regime (CAMR) went through a controversial policy development process and the newspaper media was one of the major venues in which the

SOLAR DRYING

Sun drying is a low-cost drying method but the final quality is variable while mechanical dehydration is an energy intensive process and contributes substantially to energy use and greenhouse gas emissions Many products however must be dried at relatively low temperatures i e less than 100 0C to ensure the desired product quality and solar dryers can often be used instead of sun drying

Natural drying or sun drying is the traditional and economical practice for drying the harvested crop and is the most popular method in developing countries Sometimes whole crop without threshing is left in the field only for drying For example after wheat harvesting stacks are made of 10–15 bundles of tied crop and left in the field for drying Sun drying is weather dependent
