Grinding Head Assembly for Industrial Meat Grinders

Product Specifications

Technical details and manufacturing context for Grinding Head Assembly

Definition

The Grinding Head Assembly is a precision component within an Industrial Meat Grinder with Cryogenic Cooling. It houses the rotating grinding elements and is responsible for mechanically breaking down meat into desired particle sizes while maintaining low temperatures through integrated cryogenic cooling channels to preserve product quality. Constructed from Stainless Steel 316L or Food-Grade Hardened Steel, the assembly is designed for high-throughput, hygienic meat processing. Key parameters include a rated capacity of 500–2000 kg/h at 50 Hz with a standard plate, a cutting plate diameter of 80–200 mm, and a knife speed of 1450–2900 rpm. Cutting tolerance is ±0.05 mm per ISO 2768-m, and operating pressure ranges from 1.0–1.6 MPa. The assembly operates within -10 to 80 °C, with an IP rating of IP54–IP65 per IEC 60529. Material grade options are 304–316 per ASTM A240, surface roughness is Ra 0.4–0.8 µm per ISO 4287, and weight ranges from 15–60 kg. These values are directory reference ranges and must be confirmed for the specific model and application. The assembly interfaces with the grinder's motor, feed screw, and cryogenic cooling system. Selection inputs include required throughput, particle size, meat type, and operating environment. Verification questions should address material certification, dimensional tolerances, and compliance with relevant standards. Maintenance signals include unusual vibration, increased noise, or reduced throughput, indicating wear or misalignment. Failure boundaries include operation beyond specified temperature or pressure limits, which may compromise food safety and component integrity.

Working Principle

The assembly rotates at high speeds, forcing meat through precision-cut grinding plates and knives. Cryogenic coolant circulates through internal channels to absorb heat generated during grinding, maintaining meat temperature below critical thresholds to prevent protein denaturation and bacterial growth. The rotating elements, driven by the grinder's motor, create a shearing action that reduces meat particle size. The cutting tolerance ensures uniform particle size. The assembly's design integrates cooling channels that allow cryogenic fluid to flow continuously, removing heat and keeping the meat at a safe temperature. This process preserves the quality and safety of the meat product.

Frequently Asked Questions

What materials are used in the grinding head assembly?

The assembly is available in Stainless Steel 316L or Food-Grade Hardened Steel. Material grade options include 304–316 per ASTM A240. The choice depends on the application, with 316 recommended for corrosive or acidic meat products.

What is the rated capacity of this assembly?

The rated capacity is 500–2000 kg/h at 50 Hz with a standard plate. This range is a reference; the actual capacity depends on the specific model, plate configuration, and meat type. Confirm with the manufacturer for your application.

How does cryogenic cooling work in this assembly?

Cryogenic coolant circulates through internal channels within the assembly, absorbing heat generated during grinding. This maintains the meat temperature below critical thresholds, preventing protein denaturation and bacterial growth, thus preserving product quality.

What maintenance signals indicate a problem?

Unusual vibration, increased noise, or reduced throughput can indicate wear or misalignment of the grinding elements. Regular inspection of cutting plates and knives is recommended. If operating temperature or pressure exceeds specified limits, stop operation and consult the manufacturer.
