In order to create a suitable environment and improve the quality of life people, country has paid more attention problem environmental pollution. The drying process materials accounts for large part total energy consumption. Air source heat pump is an energy-saving device that consumes small amount high low through thermal cycle, been widely used in many fields. air-source unit can provide eff...

Structural concrete exposed to marine environment deserves special attention as the diffused sea salts chemically react with harden cement matrix and forms various expansive/leachable compounds leading to loss of material, strength, cracking, spalling etc. This study cover the effect of sea water on the specimens cast from two grades of concrete exposed to simulated marine environment over a ye...

Lyophilization (freeze-drying) is one of the most suitable methods used for a long term peservation of pathogens. The aim of this paper was the application of lyophilization for storage of three significant plant pathogens: Fusarium graminearum, Helminthosporium gramineum, and Pseudomonas syringae pv. gylicinea, respectively. The plant material was collected continuously (during a four year per...

This method for determining aluminum in human serum involves electrothermal atomic absorption spectrophotometry. A longer drying time allows less pre-dilution of the sample, and the method also includes a flush cycle after atomization. Standard-addition methodology is used to eliminate matrix effects and the need for a standard curve. We used this method on serum from 50 normal persons and from...

Saving of energy and time in drying of laundry directly depends upon the residual water content of the fabric at the end of the spinning cycle. If the amount of water left in the fabric is significantly reduced then the time and energy required to dry the fabric is less. Both these factors benefit the consumer and the national energy consumption. For the USA alone, the 30 % reduction in the res...

simulation of rough rice drying is one of the proper methods for predicting moisture distribution in the product, and throughout the process of drying. the drying process must be well understood and controlled so that design guidelines which reduce or minimize drying damage to rough rice can be established and improved. therefore, an accurate understanding and description of the drying mechanis...

Doñana National Park marshes, in South West Spain, extents over 27,000 ha of the Gualdalquivir River estuary, on the Atlantic Ocean coast. The site undergoes a yearly cycle of inundation in autumn and drying out during the spring season. While flooded, Doñana wetlands create a crucial passage, breeding and wintering site for more than half million waterfowl each year, including about 150 bird s...

Variation of colour and selected physical and mechanical properties related to artificial drying of sawn silver birch (Betula pendula Roth) timber from plantations. ...

A new advanced microwave drying technology has been developed using a continuous dryer combined with an air cooler. Principle of the new technology consist in using microwave absorption filters made from special porous ceramics which act as both absorbent and transparent material for microwaves. Ceramic slabs reduce intensity of microwave radiation to such a extent which prevents overheating or...

The conventional methods of drying Chinese wolfberry fruits cause loss of active ingredients and the drying time is very long. In order to explore and investigate the new method of drying Chinese wolfberry fruits, electrohydrodynamic (EHD) drying system was used to drying for Chinese wolfberry fruits with a multiple needle-to-plate electrode on five levels alternating voltage at 0, 20, 24, 28 a...
