The Newin NWGR-300 300L Commercial Vacuum Tumbler Machine is designed for commercial meat marinating and tumbling applications. It combines a 300L drum volume with a specified 150kg charging volume, making it suitable for meat processing businesses that need batch tumbling for products such as sausage, ham, bacon, barbecue meat and poultry.
The NWGR-300 uses vacuum tumbling to combine meat and seasoning or marinade while the drum rotates. The tumbling process helps distribute the marinade through the meat during processing. The machine supports continuous and intermittent tumbling, with reverse discharge for removing processed material from the drum.
With an 8 rpm drum speed, 800mm drum diameter and 2.25kW total power, the NWGR-300 is positioned as a mid-size commercial vacuum tumbler within the Newin NWGR series.

300L Vacuum Tumbling Drum
The NWGR-300 is equipped with a 300L tumbling drum and a drum diameter of 800mm. The drum provides the working space for loading meat and carrying out the tumbling and marinating process.
The specified charging volume is 150kg. The actual amount loaded into the drum should be determined according to the product type, batch requirements and operating conditions.
Vacuum Tumbling for Meat Marinating
The NWGR-300 is designed for vacuum tumbling during meat marinating and seasoning. Meat and marinade are processed together inside the rotating drum, allowing the material to be repeatedly lifted and turned during operation.
Vacuum tumbling can be used as part of the preparation process for meat products that require seasoning or marinade distribution before further processing, cooking or packaging.
Continuous and Intermittent Tumbling
The NWGR-300 supports both continuous tumbling and intermittent tumbling. The working time and tumbling interval can be selected according to the processing requirements.
Intermittent operation can be useful when a processing recipe requires periods of tumbling followed by pauses. The appropriate operating cycle depends on the meat product, marinade and desired processing result.
Forward Rotation and Reverse Discharge
The NWGR-300 supports forward tumbling during normal processing and reverse discharge for removing the processed material from the drum.
The forward and reverse functions allow the same drum to be used for both the tumbling stage and product discharge without requiring a separate unloading process.
800mm Drum Diameter and 8 rpm Drum Speed
The drum diameter of the NWGR-300 is 800mm, with a specified drum speed of 8 rpm. The drum rotation provides the mechanical movement required to tumble the meat during processing.
The drum speed is a fixed specification for this model as shown in the supplied product parameters. If variable-frequency speed control is required for a particular application, the configuration should be confirmed with Newin before ordering.
Suitable Applications
The NWGR-300 can be used for commercial meat marinating and tumbling applications, including:
- Sausage production
- Ham processing
- Bacon processing
- Marinated meat preparation
- Barbecue meat preparation
- Poultry processing
- Commercial meat processing
The machine can be used as part of a larger meat processing line or as a standalone tumbling and marinating machine, depending on the production setup.
Choosing the NWGR-300 for Your Application
When selecting a vacuum tumbler, buyers should consider drum volume, charging volume, drum speed, available installation space and the type of meat products being processed.
The NWGR-300 provides a 300L drum volume and a specified 150kg charging volume. Its 1400 × 930 × 1350mm machine dimensions and 260kg total weight should also be considered when planning the installation area.
For a smaller production requirement, Newin also offers the NWGR-100 100L Commercial Vacuum Tumbler. For a larger batch size, the NWGR-500 500L Vacuum Tumbler provides a larger drum configuration.
Installation and Operation
Before installation, make sure the machine has sufficient floor space for loading, unloading, cleaning and routine maintenance. The 1400 × 930 × 1350mm machine dimensions should be considered when planning the installation area.
The machine should be installed and operated according to the supplied operating instructions. Before production, confirm that the vacuum system, drum rotation and discharge functions are operating correctly.
For applications requiring customized electrical specifications or optional configurations, confirm the required configuration with Newin before ordering.
🛠️ Maintenance Tips
- Clean meat and marinade residue from the drum and working area after each use.
- Clean and dry the drum and product-contact components after washing.
- Check the drum, seals and vacuum connections regularly for abnormal wear or damage.
- Keep the machine surface and surrounding working area clean after operation.
- Follow the supplied operating and maintenance instructions for lubrication, sealing components and routine inspection.
