Vacuum Rotary /
Paddle Dryers
Vacuum Rotary / Paddle Dryers provide fast, uniform, low temperature drying of press cake, filter cake, and slurry type materials requiring agitation and recovery of solvents during drying. The batch drying time depends on the composition, nature and amount of solvent present in the wet product.
Détails du produit
Consisting of a stationary horizontal jacketed cylinder (vacuum chamber) designed for vacuum or pressure operation under controlled heat with an internal revolving agitator, which can be heated to further shorten drying time. The custom-select agitator mixes and circulates the product into contact with the heated surfaces to achieve uniform drying with minimum power consumption, tumbling, and dusting.
CARACTÉRISTIQUES ET AVANTAGES
Séchoir rotatif sous vide
Due to hundreds of various types of products and demands of inducing and controlling a vacuum environment, almost all aspects of a vacuum rotary dryer’s mechanical design, operating components and ancillary support equipment can be customized to meet each individual’s process design application needs. The vast majority of Buflovak vacuum rotary dryers are installed on a production-guaranteed basis because the specific process (chemistry) design was tested and then pilot-run in the Buflovak laboratory, which provided reliable scale-up data for correct dryer configuration and working capacity to meet each individual process design application.
