Proving your cook process consistently hits safe core temperatures isn’t optional under HACCP. It’s a Critical Control Point, and auditors expect documented proof, not assumptions.

The PhoenixTM PTM1200 NT is the core of a complete thru-process food temperature profiling system, purpose-built for HACCP cook validation and food safety compliance. Rather than a standalone logger, OneTemp configures the full system around your process: data logger, thermal barrier and thermocouples matched to your product and cook method, from chicken nuggets to large ham joints.

Key features:

• Multi-channel logger (up to 20 channels) for monitoring product core temperature and oven performance simultaneously
• Identifies oven cold spots and performs Temperature Uniformity Surveys (TUS) to optimise cook programs
• Generates detailed HACCP validation reports, including Pasteurisation (Pu) and Sterilisation (Fo) lethality calculations
• Rugged thermal barrier protects the logger through ovens, steamers, chillers, freezers and fryers, for true in-process measurement from cook to chill

Typical processes:

• Batch and continuous baking ovens: breads, cakes, pies, pizza and confectionary
• Batch static and rotating ovens (steaming/roasting): poultry, meat, vegetables
• Continuous linear or spiral cookers, chillers and freezers: poultry, meat, fish
• Continuous deep fat fryers: breaded products, sausages, scotch eggs

Beyond compliance, regular use of the system supports faster HACCP validation of new and existing cook programs, process optimisation to improve throughput and reduce energy use, and rapid fault finding when manual checks flag an issue.

Every food process is different, so the PTM1200 NT system is configured to your application. Call OneTemp on 0800 104 904 to talk through your process and get a system built around it.

Designed for use in the PhoenixTM Food system range – Food Processing market for HACCP validation where both cook and chill/freeze processes need monitoring

• User replaceable batteries providing up to 1000 hours operation
• Optional 2-way RF Telemetry feature allowing live Data Logger control and temperature monitoring direct from the oven or furnace
• Bluetooth wireless Data Logger operation at reset and Download
• Mobile App Data Logger operation allowing remote reset and download
• Application of automatic Data Logger Correction Factors from the internal calibration certificate as part of CQI-9 and AMS2750 TUS operations.

Thermal Barrier Range

The data logger can be offered with a variety of thermal barriers designed to match the unique challenges of the different food applications, protecting the data logger from heat, steam, moisture and even oil. Different sized barriers can be offered to suit the specific cook process thermal requirements.

• TS14 – submersible frying, steam injection cooking or where raining water or brine showers are used.
• TS24 – dry quick high temperature bake / roast or low pressure steam cook applications.
• TS44 – long low temperature cook programs such as large meat joint / Ham stock.

Thermocouples

The food thermocouples (Type K or T) are a critical part of this system. These stainless steel tipped needle type thermocouples, comply with ANSI MC96.1 (special limits) type K or IEC60584.2 Class 1 type T specifications and are designed to give accurate, responsive product core temperature measurement. The operating temperature of the thermocouple is up to 265°C, and they have an optional locking collar to help maintain the position of the thermocouple in the product during the process. Thermocouples can be offered in a variety of different needle dimensions and also cable lengths.

Food Tray

To aid system set-up off line and installation when monitoring either linear conveyorised cookers or fryers PhoenixTM offer the Food Tray accessory option.

• System installation safe and easy on moving belt
• Thermocouple location in the product is guaranteed as thermocouples are fixed
• Product location in process consistent run to run
• Tray helps with system transfer on belt inclines (fryers)

Software

The Thermal View Food Software package is custom designed for HACCP monitoring. Provided with full industry standard lethality analysis Pasteurisation and Sterilisation values (Pu / Fo) can be calculated to accurately prove food safety. Fully certified and traceable validation reports can be produced meeting all necessary HACCP requirements quickly and efficiently.

*Cold junction compensation ensures accuracy with changing operating temperature.
