Variable Frequency Drive Vacuum Tumbling Machine
Intelligent, Adaptable Vacuum Tumbling for Precision-Engineered Meat Products
The GR Series Variable-Frequency Vacuum Tumblers represent the forefront of automated meat processing technology. Designed for processors who demand unparalleled control over texture and quality, these machines integrate a professional PLC touch-screen interface with a variable-frequency drive (VFD) for fully adjustable tumbling speeds. This combination allows for the precise replication and automation of complex cycles, including intermittent “lung breathing” vacuum functions, tailored to specific products from delicate poultry to robust ham. Paired with optional automated loading and unloading systems, they offer a complete, high-efficiency solution for achieving superior tenderness, perfect marinade distribution, maximum yield, and exceptional product consistency.

Product Highlights:
- Precision PLC & Variable-Frequency Control: The core is an industrial PLC with a touch-screen interface, allowing for multi-recipe storage and programming of all parameters. The integrated Variable-Frequency Drive (VFD) enables stepless speed adjustment from 0 to 7.5 RPM, letting you fine-tune the tumbling intensity for any product.
- Advanced Automated Cycles: Features a programmable “lung breathing” function (intermittent vacuum release) to enhance marinade penetration. The system supports full automation of total time, tumbling duration, rest intervals, and vacuum levels for hands-off, repeatable processing.
- Optimized for Hygiene & Efficiency: Includes an automatic water drain filter to efficiently remove wastewater. Designed for integration with automatic unloading and hydraulic loading systems, minimizing manual labor and maximizing production line throughput.
- Superior Tumbling Performance: The dome-shaped ends and unique curved baffles ensure a gentle yet thorough lift-and-drop action. This design maximizes protein extraction and guarantees even ingredient distribution without damaging the meat, leading to improved binding, sliceability, and product appearance.
- Robust Industrial Construction: Built entirely with food-grade stainless steel for durability, easy cleaning, and compliance with strict hygiene standards. The design ensures quiet, reliable operation in demanding environments.

In-Depth Advantage Analysis
1. Unmatched Process Control for Product Excellence
The integration of a Programmable Logic Controller (PLC) transforms the tumbler from a simple mixer into an intelligent processing station. Operators can create, save, and recall exact recipes for different products. The variable-frequency drive is critical, as it allows the tumbling speed to be perfectly matched to the product—slower for fragile items, faster for tougher cuts. The “lung breathing” function periodically breaks the vacuum, forcing marinades deeper into the meat tissue. This level of control is essential for achieving exact texture, flavor, and yield targets consistently, batch after batch.
2. Designed for Modern, Automated Production Lines
This machine is built for integration. The capability for automatic unloading and compatibility with hydraulic loading systems means it can seamlessly connect to upstream and downstream equipment. This dramatically reduces manual handling, increases safety, and elevates overall line efficiency. The automatic water drain filter further reduces operator intervention and simplifies maintenance, ensuring more uptime for production.
3. Engineered to Maximize Return on Investment
Every design choice focuses on improving your bottom line. The efficient tumbling action and vacuum technology maximize protein extraction and water binding, directly increasing cooked product yield. Precise control reduces ingredient waste by ensuring optimal absorption. The automation features lower labor costs and minimize human error. The stainless steel construction ensures long service life with minimal maintenance, protecting your capital investment.
4. Hygiene and Reliability Built-In
Constructed entirely from easy-clean, corrosion-resistant stainless steel, the machine meets the highest food safety standards. The streamlined interior with curved baffles leaves no corners for product or bacteria to accumulate. This design, coupled with robust components chosen for continuous industrial duty, guarantees reliable performance and simplifies the sanitation process, which is crucial for maintaining production schedules and product safety.
