This is a steam-heated Fluidbed Dryer which is suitable for processing batches between 50 and 150 kg depending on the characteristics of the product. The Dryer comprises a Stainless Steel Filter Housing with retractable Product Container. The base of the container is fitted with a Stainless Steel wire-mesh.
Product to be processed is placed into the Product Container which is then positioned underneath the filter housing. The filled container is placed into the opening at the base of the column and pushed upwards by a pneumatic ram. It closes against a seal at the base of the column thus forming a closed system. Air is now drawn through this system by fan – ambient air is sucked in and through a Heating Register, through the perforated base of the product container and into the product which is dispersed and thoroughly dried within the Filter Housing.
A special Filter is fitted above the product container inside the column and this prevents product particles to be sucked out of the column. During this process, the air supply is interrupted. An air exhaust duct is mounted
At the end of the drying process, the product container is released and pulled out of the column for ease of disposal.
The operator controls are located in a separate console and include temperature controls and process timers.

DE LAMA static dryer DLDR-Ex is designed to meet the highest standard of the pharmaceutical, chemical and food industries and to perform drying treatment of:
• Powders and granules
• Glassware (containers, vials, bottles)
• Empty metal containers
• Various kinds of material which require a low content of final residual humidity
• Products containing a high percentage of alcohol, solvents or other volatile materials generating vapours classified as inflammable and potentially explosive.
The machine operates with temperatures between 30°C and 80°C.
Inferior and exterior walls built around a heavy-duty, fully-welded structural frome in AISI 304 stainless steel.
Chamber made of AISI 304 stainless steel
All inferior surfaces 100% continuously welded
Floor execution for quick and easy cleaning and washdown
High grade and performance thermal insulation
Electrical panel box on the dryer or in a separate cabinet
Adjustable heating up ramp with internal humidity evacuation.
Fixed thermoresistance for regulation and flexible thermoresistonces Ptl 00
Ohm class A EN 60751 /IEC 751 for temperature monitoring inside the chamber.
Clamp connections for validation/re-validation activities.
The inner and external door surfaces are made of AISI 304 stainless steel. The opening/closing door operations are manually performed by means of lever handle. Door perfect seal is assured by a sealing gasket, special profile, in silicone rubber, suitable to withstand even high temperatures.
Exclusive deflector system for air flow regulation to optimize air distribution and temperature uniformity in any point of the chamber.
Centrifugal electrical fan group, made of AISI 316 stainless steeL for air internal recirculation and air flow changing.
Standard air heating by means of industrial steam.
Housing, made of AISI 304 stainless steel, wholly welded and air-tight with frontal plate bearing the heaters and frontal door providing access to heaters for inspection.
