Energy Use in the Biscuit-Baking Industry.

DE82905129

Publication Date	1980
Personal Author	Cleland, A. C.; Earle, M. D.
Page Count	34
Abstract	A survey was carried out to ascertain the level of energy use in the New Zealand biscuit baking industry. All firms in the New Zealand food processing industry that produce biscuits were sent a questionnaire requesting information on energy consumption and production. Replies were received from five factories and the information from these was supplemented by detailed factory surveys in two other factories. Measures to reduce energy consumption are proposed. Replacement of existing steam boilers with boilers better suited to provide the requirements for process steam would lead to significant reductions in baseload boiler fuel use. Small savings both in boiler fuel consumption and oven fuel consumption can be made by improvements to insulation. Further savings in oven fuel consumption are unlikely except by replacement of the existing ovens with more energy-conscious designs. The design of the biscuit coolers used in the industry can be improved to reduce the electricity consumed by the refrigeration equipment for these coolers. Process flow charts are presented. An analysis of energy consumption was made. (ERA citation 07:047265)
