Rotary Vacuum Paddle Dryer

Introduction

Kerone’s rotary vacuum paddle dryer are developed with over 50 years of engineering excellence, providing advanced drying solutions tailored for chemical, pharmaceutical, and agro-industrial sectors. These dryers operate under vacuum conditions to enable low-temperature moisture removal, protecting material properties and improving drying efficiency. Each unit is designed for consistent performance, ensuring uniform drying, energy efficiency, and reduced processing time.

A Rotary Vacuum Paddle Dryer is a batch or continuous industrial drying system that combines the gentle mixing action of rotating paddles with the low-temperature drying capability of vacuum operation, enabling effective drying of heat-sensitive, solvent-laden, or easily oxidized materials at significantly reduced temperatures compared to atmospheric drying. The paddles mounted on the central rotating shaft continuously turn over the material bed, exposing fresh surfaces to the heated vessel walls and distributing heat uniformly throughout the product, while the vacuum system rapidly removes the evaporated moisture or solvent vapors from the drying chamber. These dryers are particularly valued in pharmaceutical manufacturing, fine chemical production, food ingredient processing, and polymer drying where product quality and solvent recovery are paramount.

Why Choose Kerone Rotary Vacuum Paddle Dryer

Kerone’s rotary vacuum paddle dryer are trusted for their exceptional quality, robust design, and adaptability to demanding industrial applications. Every dryer is designed after detailed analysis of product characteristics, thermal behavior, and moisture content. Our focus on automation, customization, and material integrity ensures maximum efficiency and superior results.
The vacuum system design incorporates solvent recovery condensers and vacuum pump selection optimized for the specific solvent system, ensuring efficient solvent capture and compliance with environmental regulations. All wetted surfaces are fabricated from SS 316L or Hastelloy as required, with surface finishes meeting pharmaceutical standards. Kerone provides full GMP documentation, factory acceptance testing (FAT), and site acceptance testing (SAT) support to ensure seamless qualification for regulated manufacturing environments.

Types and Features of Rotary Vacuum Paddle Dryer

Kerone provides multiple configurations of rotary vacuum paddle dryer to cater to specific industrial processes. These include single-stage and multi-stage systems, batch and continuous operation, and customizable designs with advanced temperature and vacuum control mechanisms.
The dryers are available in stainless steel or special alloy construction, depending on the process requirement, ensuring high durability and resistance to corrosion and contamination.
Kerone’s Rotary Vacuum Paddle Dryers are available in horizontal and vertical vessel configurations. Horizontal Rotary Vacuum Paddle Dryers are the most common design, with the product contained in a horizontal cylindrical or trough-shaped vessel through which a central paddle shaft rotates; this provides excellent mixing and heat transfer for most product types. Vertical Rotary Vacuum Paddle Dryers use a vertical vessel with a bottom-mounted agitator, offering gravity-assisted mixing and clean discharge, and are preferred for dense or heavy materials. Double-cone Vacuum Paddle Dryers combine the gentle tumbling action of a rotating vessel with internal paddle agitation, providing very thorough mixing suitable for non-flowing or lumpy materials. Heated Paddle Dryers use hollow, steam- or hot-water-heated paddles in addition to the jacketed vessel, providing dual heat transfer surfaces that significantly increase drying rate for thick-bed materials. Vacuum levels from 0.1 mbar to 50 mbar are achievable depending on the system design.
