Reduction
1. If the particle size of the specified risk material to be rendered is more than 20 millimetres, the specified risk material shall be reduced in size using equipment specified in the licence, set so that the particle size after reduction is no greater than 20 millimetres or such smaller size as the licence shall specify. The effectiveness of the equipment shall be checked daily and its condition recorded. If checks disclose the existence of particles larger than is permitted in the licence, the process shall be stopped and repairs made before the process is resumed.
Time and temperature
2. After reduction the specified risk material shall be heated until they coagulate and then pressed so that fat and water are removed from the proteinaceous material. The proteinaceous material shall then be heated to a core temperature greater than 80°C for at least 120 minutes and a core temperature greater than 100°C for at least 60 minutes.
3. The rendering may be carried out in batch or continuous systems.
4. The specified risk material may be cooked such that the time-temperature requirements are achieved at the same time.
