Agitated Thin Film Drier (Falling Film & Raising Film)
Product Description
Thin-Film Dryers:
Dry heat-sensitive products to free-flowing powder in one step:
Artisan’s Rototherm® can produce a dry solid directly from a solution in one unit operation. It gives you the ability to dry materials that are heat sensitive, viscous and prone to foaming. You can dry solutions, slurries or wet cakes to free-flowing powder. And Rototherm is simple to operate.
Dry slurries and solutions with dissolved or suspended solids
For these applications, Artisan recommends our Rototherm® P. It is a horizontal, continuous thin/wiped-film evaporator designed to handle a wide range of difficult drying applications. Each unit is designed to meet specific customer and application requirements.
Application: Drying animal protein
- Problem:
-
Produce a free flowing powder from an aqueous animal protein solution without denaturing the protein.
- Solution:
-
Artisan’s Rototherm P, a mechanically agitated thin-film processor, is widely used to produce free flowing powders from a variety of heat sensitive products. Rapid heat transfer, plug flow, and extremely short residence time make it the most versatile “single step” processor in the industry.
- Example:
-
Rototherm P is used to dry aqueous solutions of animal proteins with an initial composition of 93% water and 7% animal protein. The material is dried under vacuum to a free flowing solid product. The short residence time in Rototherm P prevents thermal denaturing of the protein. And since a thin-film is created in Rototherm P without direct contact between the rotor and the wall, shearing and/or mechanical denaturing of the protein is prevented that would otherwise occur in a scraped surface evaporator.
Dry wet cakes or semi-dry solids
For these applications, Artisan recommends our Rototherm® D. It is a specialized, slow-speed unit designed for continuous vacuum drying or post-drying of free-flowing solid materials. It removes all traces of water and solvent from solids. Rototherm D is ideal for diffusion-limited drying applications where residence times of up to several hours are required.

About Us:
For over 75 years the experienced chemical and mechanical engineers and the skilled manufacturing craftsmen of Artisan Industries have teamed to design processes and manufacture equipment to solve the most difficult technical problems in the chemical, petrochemical, food, pharmaceutical, waste reduction, energy and power industries.
The Separations Technologies group offers proprietary thin film processes and equipment to eliminate processing steps, reduce waste and increase profitability when evaporating, distilling, concentrating or drying heat sensitive, viscous or solids-containing materials. A custom-configured pilot plant facilitates the design of customized solutions for exceptionally challenging separations.
JET-VAC® supplies ejectors in many materials for generating vacuum from steam and other motive gases with no moving parts. Jet-Vac also offers equipment to chill water using steam including waste stream for chemical, petrochemical and power plant applications.
Custom Manufacturing and Product Development Services works with many local universities as well as start-up and established businesses in the extended New England area as a one stop source for prototyping, engineering, design development and manufacturing. Artisan specializes in pressure vessels, close tolerance machining of large components and specialty welding procedures.
With the recent addition of N and NPT certifications and an NQA-1 quality control program to its long held pressure vessel (U, U2 and R) certifications Nuclear Manufacturing now designs and manufactures equipment and components for the nuclear power industry and DOE facilities.
