DVB Series – Vibratory Dryer Systems
The DB Series is ideal for shorter cycle times and for those new to mass finishing. Two different sizes are available for large and small batch sizes. Economical and durable, the DB Series are one of our most popular vibratory tumblers.
DVB Series Vibratory Dryer Systems | Vibrating Dryer for Efficient Parts Drying
DVB Series Vibratory Dryer Systems are compact industrial drying machines designed to dry parts after vibratory finishing operations. This Vibrating Dryer uses controlled vibration, toroidal motion, drying media, and heat to produce clean, dry, high-luster surfaces while helping reduce floor-space and energy requirements.
The system is designed as part of a complete vibratory finishing process and can operate as a standalone unit or as part of an automated production line. Vibrating Dryer systems are suitable for continuous operation and can also be configured for batch processing.
Vibrating Dryer for Post-Finishing Parts
A Vibrating Dryer moves finished parts through drying media while controlled vibration promotes consistent contact and movement. Kramer’s DVB Series uses drying media such as corn cob grit, walnut shell, and wood pellets to help remove moisture and support surface polishing.
Unlike simple standing heat lamps, the DVB Series uses ceramic infrared heating elements beneath the process channel. This arrangement distributes heat through the drying area and provides controlled temperature management.
The combination of vibration, drying media, and controlled heat makes the equipment suitable for parts that require drying after wet vibratory finishing. It can also provide light polishing during the drying stage.
DVB Series for Continuous and Batch Drying
The CVB Series should not be confused with the DVB Series. The DVB Series is specifically designed as a vibratory dryer system, while the CVB Series combines vibratory finishing and drying in one machine.
The DVB Series is designed primarily for continuous production but can also operate in batch applications. This flexibility allows manufacturers to use the system in different production environments and integrate it into automated finishing lines.
Kramer Industries offers DVB models from 1.5 ft³ through 20 ft³ working capacity. The available models are DVB-150, DVB-350, DVB-500, DVB-700, DVB-1100, DVB-1500, and DVB-2000. An all-in-one finishing system may be appropriate when the finishing and drying stages are planned together. Model selection should be based on part quantity, available floor space, required throughput, and the desired drying process.
Customized Vibratory Dryer Configurations
A customized Vibratory Dryer can be configured around the requirements of the finishing line. The DVB Series provides adjustable amplitude and lead-angle settings, while optional variable-frequency drives can provide additional process control.
A supply vibratory dryer should be specified around the required capacity, drying media, heat load, and production rate. Customization can also include sound covers and other production-line integration requirements. The equipment can operate as a standalone dryer or be incorporated into an automated vibratory finishing system.
The equipment can also be designed as an all-in-one finishing system when upstream finishing and downstream drying need to work together. A customized Vibratory Dryer can also be specified when standard configurations do not match the production requirement. The best vibratory finisher for the complete line should be selected together with the dryer, while the appropriate configuration depends on part geometry, drying media, production volume, moisture condition, and the required final surface condition.
Drying Media and Surface Finish
The drying media used in a Vibrating Dryer affects both moisture removal and the resulting surface finish. Kramer identifies corn cob grit, walnut shell, and wood pellets as drying-media options for the DVB Series.
Corn cob and walnut shell media can help absorb moisture while providing contact with the parts. Wood pellets can also be selected according to the application and required drying characteristics.
Media selection should consider part material, part geometry, moisture level, required finish, and whether light polishing is desired during drying. Smaller media may provide access to detailed features, while larger media can offer broader contact on more open surfaces.
Kramer Industries provides finishing and drying media options that can be matched to different production requirements. The media should be selected as part of the complete drying process rather than independently from the machine. Kramer Industries can help match drying media and equipment to the application.
Vibrating Dryer for Manufactured Components
The DVB Series is designed for a wide range of manufactured components within a complete vibratory finishing system. Typical applications include heavy stampings, heat-treated components, laser-cut parts, and general manufactured components.
For heavy stampings, the drying process can remove residual moisture following wet finishing. Heat-treated components can also be dried before subsequent handling, storage, or production operations.
Laser-cut parts and general manufactured components can similarly be processed through the drying channel after finishing. The controlled movement helps keep parts circulating through the media and supports consistent exposure to the drying environment.
Energy-Efficient Vibratory Drying
The DVB Series uses ceramic infrared heating elements beneath the process channel and insulated outer walls to help manage heat. The live Kramer design emphasizes compact floor-space requirements and energy-efficient operation.
A Vibrating Dryer can reduce the need for separate drying steps after vibratory finishing. When integrated into an automated line, the dryer can help reduce manual handling and maintain a more consistent production flow.
Carrier Vibrating Equipment describes vibrating fluid-bed dryers as a separate industrial drying technology that uses vibration and airflow to move and dry bulk solids. The DVB Series, by contrast, is designed specifically for drying manufactured parts after vibratory finishing, using drying media and heated vibration rather than fluidization. This distinction is important when comparing different industrial dryer categories.
Selecting the Right DVB Model
Model selection should consider working capacity, bowl diameter, channel width, floor-space requirements, motor power, and heat-system capacity. The DVB Series ranges from the 1.5 ft³ DVB-150 to the 20 ft³ DVB-2000.
The production process should also determine whether continuous or batch operation is more appropriate. Continuous operation can support automated production lines, while batch processing can be useful when production volumes or part types change regularly.
A Vibrating Dryer should also be evaluated alongside the finishing machine, media, compounds, and parts-separation equipment used upstream. Matching these stages can help maintain consistent production flow and drying results.

Frequently Asked Questions (FAQs)
How does a vibrating dryer work?
A Vibrating Dryer moves parts through drying media using controlled vibration while applying heat to the process channel. In the DVB Series, drying media such as corn cob, walnut shell, or wood pellets contacts the parts while infrared heating elements provide controlled heat.
What is the difference between a vibrating dryer and a fluid-bed dryer?
A vibrating dryer for finished parts can use drying media and vibration to move and dry manufactured components. A vibrating fluid-bed dryer uses controlled airflow through a bed of bulk solids, with vibration assisting fluidization and material movement. These are different drying processes designed for different material types.
Can the DVB Series be customized?
Yes. The DVB Series provides adjustable operating settings and optional configurations for production integration. Variable-frequency drives and other options can be considered when the drying process requires additional control.
What should I consider when selecting a supply vibratory dryer?
A supply vibratory dryer should be selected based on required capacity, part characteristics, drying media, heat requirements, and whether the process is continuous or batch. The DVB Series provides multiple sizes for different production requirements. Kramer Industries can also help match the dryer configuration to the intended process.
What drying media can be used in a DVB Series system?
Kramer identifies corn cob grit, walnut shell, and wood pellets as drying-media options. The appropriate media depends on the part material, geometry, moisture condition, and desired surface result.
