Temperature Monitoring System for Cryogenic Meat Grinders

Product Specifications

Technical details and manufacturing context for Temperature Monitoring System

Definition

The Temperature Monitoring System is a critical component of the Industrial Meat Grinder with Cryogenic Cooling, responsible for real-time surveillance of temperature at various points throughout the grinding and cooling process. It ensures that meat is maintained at safe temperatures to prevent bacterial growth during grinding, and precisely controls the cryogenic cooling phase to achieve the desired product texture and quality while complying with food safety regulations. The system comprises temperature sensors (typically thermocouples or RTDs) strategically placed at key locations within the grinder and cooling zones. These sensors convert temperature into electrical signals, which are transmitted to a central processing unit. The unit analyzes the data against preset thresholds, displays real-time readings on an interface, and can trigger alarms or automated adjustments to the cryogenic cooling system if temperatures deviate from the optimal range. The system is designed for integration into the grinder's control architecture, with configurable number of sensors (4–8) to match grinder size. It operates on a 24 V DC supply (reverse polarity protected) and provides a 4–20 mA output signal (HART protocol available) per IEC 60381-1. The sensor probes are made of food-grade stainless steel 316L (ASTM A240) to withstand washdown and food contact. The system's ingress protection rating is IP65–IP67 (IEC 60529), suitable for washdown environments. The electronics enclosure operates in -20 to 60 °C, while the measurement range covers -40 to 85 °C, accommodating cryogenic to ambient conditions. Accuracy is ±0.5 °C (Class A RTD tolerance per IEC 60751), with a response time of ≤3 seconds for a 63.2% step change. The system weighs between 1.5 and 3.0 kg for a complete system with 4 sensors. All specifications are directory reference ranges; verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The system uses temperature sensors (typically thermocouples or RTDs) placed at key locations within the grinder and cooling zones. These sensors convert temperature into electrical signals, which are transmitted to a central processing unit. The unit analyzes the data against preset thresholds, displays real-time readings on an interface, and can trigger alarms or automated adjustments to the cryogenic cooling system if temperatures deviate from the optimal range. The sensors are typically PT100 RTDs (3-wire) per IEC 60751, providing accurate measurements. The system's output signal is 4–20 mA, with HART protocol available, allowing integration with control systems. The processing unit can be configured to set alarm thresholds and control logic based on the specific grinder and process requirements.
