DODGEN

Devolatilizer

A static-distribution devolatilization unit designed for high-viscosity materials.

Devolatilizer Introduction

The DODGEN Falling-Strip Devolatilizer is the core hardware enabling high-efficiency devolatilisation. It consists of a heat-transfer section, a falling-strip distribution section, and a vacuum devolatilization section. With a proprietary falling-strip distributor, high-viscosity polymer melts are uniformly distributed to create a large vertical interfacial surface area, providing optimal conditions for volatile components to escape. The unit operates stably under vacuum, delivers high devolatilization efficiency, and markedly improves product quality. With no moving parts, a compact footprint and high reliability, it is an ideal choice to enhance the competitiveness of the purification stage in your polymer production line.

Equipment Structure

1 High-viscosity heat exchanger

integrates static mixing elements to achieve uniform and efficient heat transfer.

2 Falling-strip distribution system

ensures uniform distribution and continuously generates a large refreshed surface area for mass transfer.

3 Vacuum devolatilization vessel

provides a stable low-pressure environment required for volatile separation.

4 Modular structural design

facilitates installation, maintenance, and future capacity expansion.

Equipment Manufacturing

DODGEN Equipment operates an integrated in-house machining capability and supply-chain management system, ensuring full quality control for the Falling-Strip Devolatilizer from raw materials and precision machining of key internals to final assembly. We adhere to strict manufacturing standards and inspection procedures to ensure each delivered unit provides excellent performance and long-term reliability, meeting the stringent requirements of continuous industrial operation.

Equipment Advantages

1 Excellent distribution efficiency

the proprietary distributor design ensures high and stable devolatilization performance.

2 Stable and reliable operation

the static design philosophy fundamentally reduces failure rates and maintenance needs.

3 Wide viscosity window

capable of handling complex materials with viscosities up to 3000 Pa·s, enabling broad applicability.

4 Total cost advantage

both capital expenditure and long-term operating and maintenance costs are lower than the industry average.

5 Fast delivery and deployment

standardized modular design effectively shortens project delivery and start-up timelines.
