Vacuum Tray Dryer

Introduction

Kerone’s vacuum tray dryer are developed with over 50 years of engineering excellence, providing advanced drying solutions tailored for pharmaceutical, herbal, and cosmetic industries. 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 Vacuum Tray Dryer is a batch drying system in which the product, placed in shallow trays on heated shelves within a sealed, evacuated chamber, is dried at reduced pressure that lowers the boiling point of moisture or solvent and enables effective drying at much lower temperatures than would be possible at atmospheric pressure. The heated shelves provide conductive heat transfer directly to the tray base, while the vacuum enables rapid evaporation of the released moisture or solvent. Vacuum tray dryers are especially valued for heat-sensitive products such as pharmaceutical granules, APIs, natural extracts, food ingredients, electronic components, and specialty chemicals where thermal degradation, oxidation, or solvent residue are serious concerns. They are also used for drying small batches of high-value materials where product loss must be minimized.

Why Choose Kerone Vacuum Tray Dryer

Kerone’s vacuum tray 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.
Our Vacuum Tray Dryers are built with meticulous attention to chamber construction, shelf heating uniformity, vacuum system performance, and temperature control to provide the gentle, reliable drying environment required for the most valuable and sensitive products. Kerone fabricates the drying chamber and shelves from SS 316L with smooth, crevice-free internal surfaces that meet pharmaceutical GMP standards. The shelf heating system is designed for excellent temperature uniformity across all shelves and across the shelf surface — a critical parameter for batch consistency in pharmaceutical applications. The vacuum system includes high-capacity condensers to capture solvent vapours before they reach the vacuum pump, protecting the pump and enabling solvent recovery. Kerone provides complete GMP documentation and qualification support for regulatory submissions.

Types and Features of Vacuum Tray Dryer

Kerone provides multiple configurations of vacuum tray 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 manufactures Vacuum Tray Dryers in various configurations to accommodate different production scales and applications. The standard Shelf Vacuum Tray Dryers feature fixed heated shelves that hold rectangular stainless steel trays inside a bolted-door or sliding-door vacuum chamber. These dryers range from small laboratory models with 6 trays to large production units with over 100 trays.
Dual-chamber Vacuum Tray Dryers offer two separate drying chambers that can operate simultaneously or alternately, optimizing chamber usage for continuous production facilities. Inert gas backfill systems can be added to replace the vacuum with nitrogen after drying, protecting oxidation-sensitive products during unloading.
Vacuum Tray Dryers with integrated milling systems allow dried products to be discharged directly into an attached mill, breaking up dried cakes into granules without air exposure. Key features include Pt-100 temperature sensors on each shelf, vacuum gauges, digital controllers, and alarm systems.
