Hybrid Vacuum Dryer

Introduction

The Hybrid Vacuum Dryer removes moisture and solvents from products under reduced pressure, which lowers the boiling point of the liquid so that drying can happen quickly at low temperatures. This protects heat-sensitive, oxidation-prone and high-value materials that would degrade in hot air. The hybrid design combines more than one means of supplying heat to the product under vacuum, for example a jacket or shelf heated by hot water, steam or thermic fluid and supplemented by electric or heat pump-generated hot water, sometimes along with agitation or radiant heating. Heat is delivered mainly by conduction, so little air is needed, and vapours are removed through a condenser and vacuum pump, which also allows solvent recovery. For pharmaceutical, fine chemical, food and specialty material producers who value quality, purity and solvent control, the vacuum dryer is an indispensable tool.

Why Choose Kerone Hybrid Vacuum Dryer

Vacuum drying involves careful balancing of heat transfer, vacuum level and vapour handling, and Kerone designs the complete system rather than a vessel alone. We match the dryer type, agitation, heating medium, condenser and vacuum pump set to your product and solvent. Heating arrangements such as hot water with electric trim, or thermic fluid with heat pump support, are suggested for better temperature accuracy and lower energy use. Chambers are leak-tested for vacuum integrity and built in SS 304, SS 316 or higher alloys for corrosive solvents. Safety features, including pressure relief, interlocks and nitrogen purge, can be included for solvent-laden duties. Kerone offers documentation, validation support and operator training, backed by after-sales service that helps you keep a vital process running reliably.

Types and Features of Hybrid Vacuum Dryer

Kerone supplies Hybrid Vacuum Dryers in vacuum tray, rotary cone, conical screw, agitated nutsche and paddle designs. Vacuum tray or shelf dryers suit small to medium batches of delicate products without agitation. Rotary cone vacuum dryers tumble powders gently for faster, more uniform drying and easy discharge, while conical screw and paddle dryers deliver intense mixing for sticky or lumpy materials. Heating is through jackets, hollow shelves or agitators with hot water, steam, thermic fluid or electric elements, and many models allow combined heating. Typical features include a high-integrity vacuum seal, condenser and receiver for solvent recovery, a suitable vacuum pump such as liquid ring, dry screw or rotary vane, filter arrangement to stop dust carry-over, temperature and vacuum sensors, and PLC-based controls with data recording.
