Thin Film Dryers - Used and Surplus Inventory | IPP

Thin film dryers are specialized dryers designed to process viscous liquids, slurries, and pastes under vacuum or atmospheric conditions. These dryers use a rotating wiper system to spread the feed into a thin, turbulent film across a heated cylindrical surface, allowing for rapid moisture or solvent evaporation. With over 47 years of process equipment experience, IPP offers a global inventory of used, secondhand and surplus thin film dryers from 20 plant sites and more than 15,000 ready-to-ship systems.

Thin film technology is prized in industries requiring precise temperature control, short residence times, and gentle handling of sensitive compounds. The continuous design makes it ideal for solvent recovery, devolatilization and concentration tasks.

Primary uses across industries

In pharmaceutical manufacturing, they process APIs, intermediates, and solvent-based products
In fine chemicals, they dry slurries and high-viscosity compounds without thermal degradation
In polymer and resin production, they assist in devolatilization and final drying
In food and nutraceuticals, they handle pastes, oils and extracts with minimal thermal stress

Types of materials processed

High-viscosity fluids, pastes and slurries
Heat-sensitive or oxygen-sensitive materials
Solvent-rich products requiring closed-loop recovery

Common materials of construction

Thin film dryers must withstand corrosive materials, high temperatures and pressure differentials:

Stainless steel for sanitary and general chemical use
Hastelloy and other alloys for corrosive or solvent-rich environments
Glass-lined options for ultra-pure or reactive applications

Key features of thin film dryers

High surface area for rapid heat transfer
Short residence time protects heat-sensitive compounds
Continuous operation under vacuum or atmospheric pressure
Integrated solvent recovery options
Compact footprint with high throughput

FAQ

Dryer-Thin Film FAQ

Have questions about Thin Film Dryers or our services? Learn more about our products and why customers choose IPP.

What makes thin film dryers ideal for heat-sensitive materials?

The short residence time and efficient heat transfer minimize thermal stress, protecting delicate products during evaporation.

How do thin film dryers compare to rotary or shelf dryers?

Thin film dryers offer continuous operation and better handling of viscous or solvent-heavy feeds, while rotary and shelf dryers are better for bulk or static drying.

What are the key maintenance needs for thin film dryers?

Maintenance includes monitoring rotor clearance, seal integrity, and surface fouling on the heated wall.

What are the benefits of buying used or secondhand process equipment from IPP?

IPP offers deep savings, faster project timelines, and access to a trusted global inventory built over 47+ years.
