The Condry® conical bottom agitated vacuum pan dryer was developed to process a wide variety of products. The machines have proven to be particularly suited for the drying of difficult products such as agglomerating, sticky as well as heat sensitive products. Simultaneous rotational and vertical agitator motions result in a very efficient and even mixing of the entire product mass and permit to overcome critical phases during the drying process. The conical bottom allows for excellent product discharge characteristics. In compliance with cGMP and FDA guidelines: - agitator supported by the top head, with the seal in contact with the vapours only - excellent cleanability using CIP Systems, with simple validation process Calculation, design and manufacture in accordance with ASME pressure vessel code, Section VIII, with U-Stamp and/or Pressure Equipment Directive (PED) 97/23/EC.

Suited for drying difficult agglomerating sticky heat sensitive products. Agitator with vertical movement in addition to its rotational movement assures agitation of total product volume and permits to overcome critical phases during the drying process.

Main advantages:

Excellent product discharge characteristics

High efficiency and thus short drying times

Simple operation and easy validation

Ease of cleaning and inspection

Operational flexibility

Total electric design available for special pharmaceutical and / or sterile applications

A unique agitator arm profile with teeth has been developed. Excessive pressure onto the product is avoided and thus prevents changes or damage to the crystal structure of the product and at the same time results in excellent mixing characteristics at the desirable low rotational speeds. The agitator design prevents the formation of agglomerates, thus no choppers (homogenizers, lump breakers) are required, which are highly undesirable due to their shear action causing damage to sensitive products in addition to the excessive dust being created in the final drying stages.

The agitator arms are designed to have large surfaces to obtain comparatively large wetted surface areas available for maximum possible heat transfer to heat and cool the product respectively.

Supplemental microwave heating is available as an option for the best possible drying performance.

Narrow tolerances between the agitator and the vessel walls prevent adhering of the product to the walls and thus result in a good heat transfer, good emptying characteristics and permit the use of the dryer with small product volumes.

Containment devices “Glove Box” are applicable for toxic products handling and operational safety.

Control systems are available for the levels of automation desired, with PLC/PC based systems, with recipe management, slaved to DCS systems etc.
