YPG -P Pressure Pharmaceutical Spray Drying Machine ( Spray dryer ) (Nozzle TOWER )( High pressure spray drying Machine )

Preface

The material is sprayed into fine mist by nozzle on the top of tower. Follow the heat wind, the material is dried. The machine‘s characteristic is high collection rate, no stick onto the wall, energy saving, high efficiency, especially applicable for heat sensitive material. It's widely used in food, dyestuff, chemical industry and so on.

High-Pressure nozzle atomization is used especially for products where a rather coarse powder with narrow particle distribution and high bulk density is required. In the nozzle atomizer, fines are returned around one or more central nozzles in order to facilitate optimum agglomeration. Two-Fluid nozzle agglomeration is typically applied in small chambers allowing maximum flexibility in particle design and particle engineering for both super-fine and agglomerated particles.

The NOZZLE TOWER Spray Dryer is designed specifically for production of free-flowing powders made up of single, individual, round, and soluble particles. To meet the various requirements of different industries, it is available in several designs. Its qualities have achieved worldwide renown among producers in the food and chemical industries.

Drying air is introduced at the top of the drying chamber through an air disperser designed to obtain a controlled low velocity airstream downwards in the drying chamber. The product, is atomized by a set of nozzles placed just below the air disperser. This ensures a gentle drying of the particles as they pass through the drying chamber. The design ensures a long residence time in the chamber.

Feature :

The drying air is exhausted from the drying chamber through the "bustle", formed by an enlarged conical section. The smallest entrained particles are separated in the Bag Filter, from where they can be returned to the nozzles for agglomeration or discharged directly into a pneumatic cooling and conveying system. The main fraction can be pre-cooled by introducing cooling air into the lower part of the chamber cone prior to product discharge into the conveying system for bagging-off.

The NOZZLE TOWER is also available in a counter-current version with fountain nozzles for heavy feed stocks typically pertaining to the chemical industry.
