  Many industries, including the food, chemical, and pharmaceutical product industries, rely heavily on precise information of the moisture content of their products as a part of quality control. Such measurements required to be fast and reproducible in order to permit for immediate correction of the work flow if any flaw appears in the final product. Both direct and indirect methods are used. Only the direct methods actually measure the moisture content; the indirect techniques only calculate it from alternative indirect indicators. Direct Methods  : Many devices for LOD measurement use the thermo gravimetric principle. This uses the total loss of weight incurred by the sample on drying to calculate the moisture content. Drying ovens  are based on convection heating of the sample by circulating hot air. Sometimes a vacuum is added to speed up the drying process. Infrared radiation  is used in many moisture analysers, such as halogen moisture analysers which are used to produce infrare

  Typically, powder-drying operations involve the application of heat to a solution, wet powder or slurry. Bulking and packaging of the dried powder usually follows. Common   dryer   types include tray,   fluidized bed , and   spray, rotary   and   vacuum dryers . In any type of dryer, the dry powder can build up as a bulk or layer in various locations within the dryer, or in downstream   process equipment   or ultimately in hoppers, silos, big bags or smaller packages. Safe Powder Drying Evaluation of self-heating hazards of powders The first step in ensuring safety from fires and explosions in drying operations is having a proper understanding of the thermal instability properties of the powder (including its potential for gas generation), dust cloud explosibility and gas flammability. Powder self-heating hazards can occur when the temperature of the powder in bulk or layer is raised to a level at which the heat generation rate by the exothermic reaction exceeds the rate of heat lost

  Wood drying (also seasoning lumber or wood seasoning) reduces the moisture content of wood before its use. When the drying is done in a kiln, the product is known as kiln-dried timber or lumber, whereas air drying is the more traditional method. There are two main reasons for drying wood: Woodworking : When wood is used as a construction material, whether as a structural support in a building or in woodworking objects, it will absorb or expel moisture until it is in equilibrium with its surroundings. Equilibration (usually drying) causes unequal shrinkage in the wood, and can cause damage to the wood if equilibration occurs too rapidly. The equilibration must be controlled to prevent damage to the wood. Wood burning : When wood is burned (firewood), it is usually best to dry it first. Damage from shrinkage is not a problem here, as it may be in the case of drying for woodworking purposes. Moisture affects the burning process, with unburnt hydrocarbons going up the chimney. If a 50% w

  A heat exchanger is a system used to transfer heat between two or more fluids. Heat exchangers are used in both   cooling and heating processes . The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. Another example is the heat sink, which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant. There are three primary classifications of heat exchangers according to their flow arrangement. In parallel-flow heat excha

  Dehumidifying or drying plastics in the process phase may be a important part of injection molding. Drying plastic resin utilized to reduce or eliminate complications that will be caused by an excessive amount of moisture in an exceedingly plastic material. The extent to that moisture affects the quality of a molded part is set by {the specific the precise the particular plastic resin being processed and therefore the supposed purpose of the part. this article can discuss 2 categories of resins as well as the benefits of drying plastic material. Hygroscopic vs. Non-Hygroscopic Each kind of resin contains a set of process characteristics that have a definite affinity to assemble moisture. These 2 groups of polymers discuss the distinction between hygroscopic and non-hygroscopic polymers. Hygroscopic Polymers These polymers include Nylon, ABS, Acrylic, PET, PBT, polyurethane, Polycarbonate, and many more. These resins absorb moisture internally and unleash moisture through the air. Any

  Generally the term ‘ceramics’ (ceramic products) is utilized for inorganic materials with presumably some organic content, created from non-metallic compounds and made permanent by a firing method. In addition to clay primarily based materials, these days’ ceramics embrace a large number of products with a little fraction of clay or none at all. Ceramics may be glazed or unglazed, porous or glassy. Firing of ceramic bodies induces time-temperature transformation of the constituent minerals, typically into a combination of recent minerals and glassy phases. Characteristic properties of ceramic merchandise embrace high strength, wear resistance, long service life, chemical inertness and non-toxicity, resistance to heat and fire, (usually) electric resistance and generally also a particular porosity. Two kinds of energy are utilized in the ceramic industry; electrical energy and chemical energy. The electrical energy is employed in 2 completely different ways; energy once utilized in th
