Introduction

Kerone’s Fluid Bed & Vacuum Combination Dryer pairs rapid fluidised drying with a low-pressure finishing stage to dry granules, powders and crystalline solids that need both speed and gentleness. In the fluid bed stage, heated air flows upward through the product bed, suspending the particles and exposing every surface to the gas stream, so surface moisture and loosely held solvents are removed quickly. For the second stage, the system can transition to reduced pressure, either in the same vessel or in an attached vacuum chamber, so tightly bound moisture or residual solvent can be removed at lower temperatures and with minimal oxidative exposure. This sequence shortens total cycle time compared with static vacuum drying, while also reaching lower residual levels than a fluid bed alone. It is widely used in pharmaceutical granulation, specialty chemicals and nutritional ingredients where product temperature, residual solvent and particle integrity are critical.

Why Choose Kerone Fluid Bed & Vacuum Combination Dryer

Drying a solvent-wet granule is a balance between speed, safety and quality. Kerone’s design starts with the product’s flow behaviour, particle size, friability and solvent profile. The air distributor plate, product container, filter system and exhaust ducting are sized to achieve stable fluidisation without excessive attrition or filter blinding. When flammable solvents are present, the equipment can be built with explosion-pressure-shock-resistant construction, earthing and nitrogen-inerted closed-loop circuits that condense and recover solvent vapour. The vacuum stage is engineered with appropriate seals, filtration and a condenser or cold trap so that residual solvent is removed without contaminating the pump. Product temperature probes, differential-pressure monitoring and recipe-driven control allow operators to repeat validated drying profiles, while clean-design details and wash-in-place options support hygiene needs. With Kerone, you gain a drying system that shortens cycles, protects particle properties and fits regulated production.

Types and Features of Fluid Bed & Vacuum Combination Dryer

Kerone offers batch fluid bed dryers with vacuum-capable chambers, closed-loop nitrogen systems for solvent-wet products, and sequential layouts in which material is transferred from a fluid bed stage to a separate vacuum finishing vessel. Container-based designs allow product to be loaded and discharged on trolleys, while multi-chamber continuous versions suit larger throughput. Some configurations apply vacuum-assisted fluidisation, which reduces the operating pressure and drying temperature while keeping the bed suspended with controlled gas flow. Typical equipment includes retractable product containers, stainless-steel or Hastelloy contact parts where required, bag or cartridge filters with shake-down or pulse cleaning, inlet air heaters or nitrogen heaters, solvent condensers, differential-pressure and temperature sensors, and optional integrated spray systems for granulation, coating or agglomeration before drying.

Key Features

  • Two-stage drying logic: Fluidised bed drying removes surface moisture quickly, then vacuum drying lowers moisture or solvent to very low levels.
  • Excellent heat and mass transfer: Suspended particles are exposed to the gas stream, speeding up evaporation and avoiding hot spots.
  • Low-temperature finishing: Reduced pressure removes bound moisture and residual solvent without heating the product excessively.
  • Closed-loop inert operation: Nitrogen circuits and solvent condensers permit safe drying of flammable-solvent-wet products.
  • Explosion-conscious design: Pressure-shock-resistant construction, earthing and relief devices address dust and solvent hazards.
  • Gentle particle handling: Controlled airflow and optional vibration or pulsed flow reduce attrition and protect granule structure.
  • Efficient filtration: Bag or cartridge filters with automated cleaning retain fines and maintain stable airflow.
  • Process monitoring and control: Bed temperature, exhaust humidity, pressure drop and recipe control support repeatable results.

Applications of Fluid Bed & Vacuum Combination Dryer

Kerone’s Fluid Bed & Vacuum Combination Dryers are extensively used in industries where granular products require fast drying with very low residual moisture or solvent. Typical applications include:
    • Drying pharmaceutical granules, pellets and solvent-wet active ingredients before tableting or encapsulation.
    • Processing nutraceutical and vitamin granules with sensitive active compounds.
    • Finishing agrochemical granules and crop-protection formulations.
    • Drying specialty chemical crystals, catalyst supports and fine ceramic powders.
    • Conditioning food ingredients such as sweeteners, flavour carriers and probiotic granules.
    • Drying and conditioning polymer additives, resins and engineered powders.
Kerone’s Fluid Bed & Vacuum Combination Dryer brings together the speed of fluidised drying and the precision of vacuum finishing to give processors faster cycles and lower residual moisture or solvent levels. Its gentle particle handling, closed-loop and inert options, and detailed process monitoring make it a strong choice for regulated, solvent-sensitive and high-value granular products. Whether you are scaling up a pharmaceutical granulation or refining a specialty chemical process, Kerone can help you select the appropriate batch size, filtration, inerting and vacuum features.

Frequently Asked Questions (FAQ)

  • A fluid bed dryer is excellent for surface and loosely bound moisture, but tightly held moisture or residual solvent can require long times or high temperatures. Adding a vacuum stage removes it gently and more completely.
