Heat Recovery and Energy Saving Using a Baker Perkins Simplex 2000 Bread Baking Oven. A Demonstration at Mothers Pride Bakery

摘要

A report is given of a new bread oven, a Baker Perkins Simplex 2000, installed at British Bakeries' Watnall plant under the Energy Efficiency Demonstration Scheme. The energy saving features include 1) a new design of heating system, 2) combustion air pre-heated with burner flue gases, 3) heat recovery from oven chamber to heat hot water and 4) an in-line lidding system. Results are presented for an independent monitoring of both the new oven and one of a conventional design to compare energy consumption and performance. It is shown that the simplex 2000 reduced energy costs at the Watnall plant by Pound 45,900/year. Additional benefits of the new oven include reduced production labour requirements and an increase in productivity of 100% compared with previous models. (ERA citation 12:004182)
