Abstract
An energy efficient method of sterilizing canned food in a sterilizing kettle comprises the use of 95.degree. C. hot water, which is kept in a first reservoir, to expel the air in a sterilizing kettle containing the canned food to be sterilized and to preheat the kettle and the canned food. The 95.degree. C. hot water is cooled to become 85.degree. C. hot water, which is then drained out of the kettle to be kept in a second reservoir. Thereafter, steam is injected into the kettle to sterilize the canned food. The 85.degree. C. hot water kept in the second reservoir is then introduced into the kettle in which the 85.degree. C. hot water is converted by a heat exchange to the 95.degree. C. hot water, which is then drained and kept in the first reservoir for use again in the next sterilization cycle.
