DETAILED DESCRIPTION The Industrial Vacuum Meat Tumbler (Model GR-500) is a professional machine developed by Yuanchang for tumbling, marinating, and treating meat products in industrial environments. Its vacuum system promotes the penetration and distribution of marinating solutions throughout the product while helping improve the texture and characteristics of the processed product. The GR-500 is designed for meat processing plants, sausage factories, and industrial meat production lines requiring uniform and controlled treatment of raw materials. Its adjustable drum speed allows the process to be adapted to the characteristics of different products and production requirements. TECHNICAL SPECIFICATIONS: Model: GR-500. Equipment Type: Industrial vacuum tumbler for meat products. Loading Range: 20–50%. Installed Power: 1.65 kW. Drum Speed: 2–8 rpm, adjustable by variable frequency drive. Vacuum Level: −0.085 MPa. Electrical Supply: Three-phase, 5-wire system. Construction Material: SUS304 stainless steel. Weight: 420 kg. Dimensions: 1,650 × 1,230 × 1,420 mm. DESIGN AND TECHNOLOGY FEATURES: Vacuum Processing: The vacuum system allows processing under controlled conditions to promote the absorption and distribution of marinades and treatment solutions throughout meat products. Adjustable Speed: The drum speed can be adjusted between 2 and 8 revolutions per minute using a variable frequency drive, allowing the treatment intensity to be adapted to each type of product. Stainless Steel Construction: Manufactured from SUS304 stainless steel, the machine provides a robust structure suitable for the hygiene requirements of the food industry. Uniform Product Treatment: The controlled movement of the drum promotes uniform treatment of meat and other meat products during the tumbling and marinating process. Industrial Design: The GR-500 is designed for integration into industrial plants and meat processing lines requiring stable and repetitive operation. INDUSTRIAL APPLICATIONS: The GR-500 model is particularly suitable for: • Industrial meat processing plants. • Sausage and frankfurter factories. • Pork, beef, and poultry processing. • Meat product marinating lines. • Vacuum tumbling and treatment processes. • Prepared meat product manufacturing. • Industrial food processing lines.
