Process

Tray drying is a batch process used to dry materials that are liquid or wet cake. The input materials are batched, placed into trays and loaded into AVEKA’s overhead ovens for drying. Tray drying works well for material that requires more gentle processing or cannot be atomized in an air stream due to viscosity. The resulting product can vary widely based on chemical and physical characteristics.

AVEKA utilizes ovens equipped with electric or steam elements, forced recirculating air and forced exhaust. Furthermore, nitrogen purging and explosion proof ovens are available for solvent evaporation. Trays are typically constructed from aluminum or stainless steel, or custom drying trays can be made to maximize efficiency. AVEKA’s full-service analytical laboratory allows for rapid process adjustments during trials and excellent quality control for production operations. For example, tray dried products can be characterized by measuring volatile content. Additionally, extensive pre- and post-processing capabilities contribute to the turnkey experience AVEKA provides.
