TRAY TRAY DRYERDRYER
A tray or Compartment Dryer is an enclosed insulated chamber in which trays are placed on top of each other in trolleys. The material to be dried either wet or solids are placed in the trays. Heat transfer is by circulation of hot air by electric heaters or steam in radiator coils. Blower fans are installed inside to ensure proper circulation and transfer of heat. A control panel to control the temperature and other parameteres is fixed outside the dryer. These dryers are available in Mild Steel, Stainless Steel or Al construction. Used for Drying of Pigments, Food, Bakery, Electrodes, Chemical and Plastic Powders.

Designed to produce fine granular or powdered material. the Drytec Flash Dryer uses a stream of turbulent hot air to dry material in a continuous cycle, evaporating water from the particulates. Dispersed in the air these particles have a large surface area enabling extremely high rates of heat and mass transfer to be achieved. Rapid evaporation during the process cools the air to minimise damage to sensitive materials.
Drytec Ring and Flash Dryers are ideal for drying filter cakes, fibrous materials, sludges and particulates.

37
Open system
Featuring atmospheric air in a once-through system where water is to be removed. Normally a push-pull system is used to balance the pressure to be slightly negative in the free board of the fluid bed. Depending upon the product and available heat source, direct or indirect heating may be applied. The exhaust air is cleaned by e.g. bag filter, cyclone with or without wet scrubber. In cases where products pose a dust explosion risk, open cycle systems feature pressure shock resistant components or alternatively semi-closed cycle, self-inertizing layouts can be considered.
38
39
Closed cycle system
Featuring drying in an inert gas atmosphere (usually nitrogen) recycling within the system. It must be used for drying feedstocks containing organic volatiles or where the product must not contact oxygen during drying.Closed cycle systems are gastight, and addition of inert gas is controlled by monitoring the oxygen content of the drying gas and the system pressure, which is kept positive. The evaporated volatiles are recovered in a condenser.

Fluid Bed Dryer
Fluid Bed Dryer is designed for rapid and uniform drying of crystals, powders and medium size pellets. A fan draws fresh air and passes the air through a filter and is heated to produce warm air either by electric heaters or by steam. The hot air passes through the product container having diffuser plates and sieve. Due to the air stream the wet product gets fluidised. The material gets surrounded by hot air which gets dried due to heat transfer. Moist air passes thorough a filter bag and exhaust dust

OPERATION:
Due to induced draft created by specially
designed heavy duly fan the atmospheric
air is drawn through the 5 micron air filter.
The filtered air is then heated to the
required temperature by electric heaters /
stream radiator. The hot air passes
through the product container and the
product gets dried by air fluidisation and
the air circulation is controlled by damper.
The filter bag prevents fine particles from
carrying over to exhaust air stream.

GMF-Gouda drum dryer
67
GMF-Gouda drum dryer….. The drum body of the drum dryer is heated on the
inside by steam. A special composition of cast iron gives the drum a combination of favourable properties: very accurate shape retention even at high steam pressure and temperature, and excellent "scraping properties", which are utilised by the scraping knife.
Steam heating gives a uniform temperature distribution over the drum surface and this results in consistent product quality. The steam condenses on the inside of the drying drum. The condensate is continuously removed from the drum, so that the largest possible surface area remains available on the inside of the drum for condensation of the steam. The steam system is a closed system, which means that the product cannot come into contact with the steam or condensate.
