Weathering Process Physical Weathering Processes Freeze Thaw (Frost Shattering) Temperatures need to fluctuate above and below freezing. When the temperature drops below 0 degrees‚ water collected in rock cracks freezes and expands. When temperatures rise again the ice melts. Pressure created by expansion results in progressive weakening of the rock. At high altitudes frost-shattered material forms scree slopes. Heating & Cooling Thermal expansion & contraction of rock in response

dehydration. Usually‚ foods‚ which are concentrated‚ remain in the liquid state; while drying produces solid or semisolid foods with significantly lower water content. The concentration of liquid foods has three different methods; evaporation‚ membrane concentration‚ and freeze concentration. Evaporation usages gas liquid phase separation. It has the lowest capital cost and the maximum concentration for freeze concentration is more than 50 Brix. Membrane concentration can be used for separating components

Saraf Foods Investment (A) In August 1999‚ Vishnu Varshney‚ head of Gujarat Venture Finance Ltd. (GVFL)‚ a venture capital firm in the state of Gujarat‚ India‚ was assessing the investment of GVFL in Saraf Foods Ltd. Saraf Foods was a producer of freeze dried vegetables for export. The latest monitoring report showed the financial projections for Saraf Foods for FY 1999-2000. 1998 had been a particularly bad year as a huge increase in the price of raw materials and restrictions on exports had increased

Fish products are preserved using almost every food processing technique that has ever been develop(drying‚ smoking‚ freezing‚ canning‚ fermenting‚ high pressure processing)‚ and of course‚ there is the increasing trend towards the consumption of high quality raw fish in the form of sushi. All of this variety does of course mean that the microbiology of

Instant coffee‚ or soluble coffee‚ which is a beverage in liquid form made from coffee and can be soon reconstituted by adding water‚ has been a popular product for decades (Allwords‚ n.d.). People has gradually become so used to drinking instant coffee that some even did not know what the fresh-brewed coffee tastes like which was found as a result of tastes tests made by at least one manufacturer (Stacey‚ Blachford & Cengage‚ 2002). It would seem that the innovation of instant coffee could make

and thawing. A concrete with low permeability resists ingress of water and is not as susceptible to freezing and thawing. Water enters pores in the cement paste and even in the aggregate. Absorption For concrete pavers‚ the test procedure involves drying a specimen to a constant weight‚ weighing it‚ immersing it in water for specified amount of time‚ and weighing it again. The increase in weight as a percentage of the original weight is expressed as its absorption (in percent). The average absorption
