DRYING PLANTS

TS FLUIDIZED BED DRYERS

The “TS” dryers are the most efficient fluidized bed dryers which are used in chemical, food treatment and pharmaceutical industry. Having a very high thermal efficiency and built both as continuous or batch operating equipments, the “TS” have been utilized to threat thousands of different products such as organic or inorganic powders or paste, inorganic liquids. The principal of operation depends on “Fluidization” in which drying of water or solvents in open or closed cycle is performed by the suspension and agitation of a bed of particulate solids by a vertically rising stream of gas.

The TS dryers are manufactured as:  

Batch operated TS: It is used for little batches of pharmaceutical products. Continuous TSA: It is used for temperature sensitive products. Continuous tower type ETS: They are special plants: the former is useful to change the drying conditions zone by zone, the latter for dangerous products or very fine dusts. Continuous discharge TS/S Continuous loading TS PULSE

TSF TURBOFLASH DRYER

The TSF Turboflash dryer is a new patented dryer designed to treat continuously temperature sensitive products. The dryed material is continuously discharged as powders or granules. Owing to the low drying time the product can not reach an high temperature. TSF Turboflash dryers are used to perform two different and opposite process conditions.

• “TSF” for dust: In this system products such as organic powders or temperature sensitive slurry (starch, micelium, flour...) are reduced in dust and immediately dryed and discharged by cyclons.

• “TSF” for muds: This system is used for organic slurry (biological mud). The mud produced by the water treatment plants are dryed in order to reduce the cost of elimination.

ALFA DEHYDRATORS

The ALFA Dehydrator is an half pneumatic three passages apparate, designed to treat many organic or inorganic products (fodders, by-products of food industry, olive husk, paper pulp) in small pieces with high initial moisture too.

The heart of the plants is the rotary drum. The drying product is carried by the air flow and the drum rotation. Drying is produced by the hot air flow that is directly mixed with the product in the rotary drum of the equipment.

The “ALFA” dryers are manufactured:

• ALFA:              for general purpose

• ALFA/S:           for olive husk

ROTARY DRYERS

The rotary dryers are all the equipments in which the product is dryed inside a rotary drum. The material can be dryed by direct hot air ventilation both in parallel and counter current. Rotary dryers are built in following types:

• R: Direct heating rotary dryers: The drying product is lifted by the internal showels and falls in the hot air stream, that performs the drying. The heat transfer coefficient is low. So those are to be utilized with high air inlet temperature. Some tipical fields are mining, sands, bentonite and industrial not combustible slurry.

• RI: Indirect heating rotary dryers: The drying material is heated across the drum walls. The drum is enclosed inside an insulated jacket in which hot gas flows. The hot gas is generated by a burner. The RI equipment are indispensable for some products that are to be treated with high temperature and low oxigen contents. Some tipical fields are drying of danger or explosive products, oil drying from metallic granules, water of crystallization removal and chemical reactions at high temperature and controlled atmosphere.

• RC: Calciners: The product of flows in counter current with the hot air stream and is heated at a temperature ranging from 800 to 1500 °C. Some tipical fields are mineral treatment, purification of industrial waste and chemical industry.

CABINET AND TUNNEL DRYERS
Tunnel and cabinet dryers are plants composed by a metallic and insulated “room”, sometimes made by brickworks, in which circulate an hot air stream. The drying product is placed on wood or metallic trays supported by wheeled trucks.
The main available models are: Tunnel dryer GHIBLI FCN Tunnel dryer GHIBLI SILA Cabinet dryer LIBECCIO Cabinet dryer SCIROCCO
The tunnel dryers are usually employed to treat fruit and vegetables. For the cabinet dryer the Libeccio type is designed for fruit, and the Scirocco, insulated for high temperature, is employed in chemical and pharmaceutical field.
