Abstract
The use of grains that has bacillus like salmonella may have lost domestic animal's health. To avoid this problem, we have devised a new process. The process involves shock heating by piston compression using the high pressure exhaust gases. Experiment results show that the maximum pressure increased and then the heating times reduced to 120μs, as the equivalence ratio increased. And the process proved to be able to sterilize the bacillus about 96%. We found that both high pressure and heating time affects the sterilization, and that the heat treatment of grains can sterilize bacillus.
