March Adjustment and control of moisture levels in solid materials through drying is a critical process in the manufacture of many types of chemical products.
Selected Definitions Drying: It can be defmed as an process in which the liquid, generally water, present in a wet solid is removed by application of heat and fmally a liquid free solid product is obtained. Bound Water: It is the moisture content of a substance that exerts a equilibrium vapor pressure lower than that of the pure liquid at same temperature. Unbound water: It is the moisture content of a substance that exerts a equilibrium vapor pressure equal to that of the pure liquid at same temperature.

The rotary dryer also known as tumbling dryer is an equipment employed to minimize the moisture content of feed materials by bringing it in direct contact with a heated gas. The movement of the material is due to the combined effect of inclination of the shell to the horizontal and the internal tumbling action or mechanical turn over thus the name tumbling dryer. The nature of the feed determines the directions of gas flow through the cylinder and it is relative to the solid. This drying equipment can also perform batch or continuous processing of the wet feed. A rotary dryer is said to be of the direct type if, by virtue of its design, heat is added to or removed from the solids by direct exchange between the gas and solids. The direct heat dryers are the simplest and the most economical class. They are used when direct contact with the hot gas or air is not detrimental to the fed.
Компьютерные вирусы столь же разнообразны, как и те, что поражают человека. Подобно своим природным аналогам они преследуют одну цель - внедриться в организм и начать размножаться. В данном случае организмом является ТРАНСТЕКСТ. Чатрукьяна всегда изумляло, что АНБ никогда прежде не сталкивалось с проблемой вирусов. Сквозь строй - надежная система, но ведь АНБ - ненасытный пожиратель информации, высасывающий ее из разнообразнейших источников по всему миру. Поглощение огромных объемов информации сродни беспорядочным половым связям: какие меры предосторожности ни принимай, рано или поздно подхватишь какую-нибудь гадость.
