Energy-saving technology enhancing the efficiency of the Baker Perkins Microfilm confectionery cooker has been introduced by Baker Perkins. Optional features reduce energy consumption by reclaiming process heat that would otherwise be wasted.
The Microfilm is a versatile cooker that sits at the heart of many Baker Perkins AutoCook systems. The rapid, thin-film process is suitable for most types of sugar, low-sugar and sugar-free lollies, including those with dairy components.
The first new feature captures flash vapour released by the product between the pre- and final-cook stages and normally vented to atmosphere. In the latest system it is passed through a heat exchanger to heat water for use in hot water systems or process applications.
The second method uses the high-temperature condensate from the steam heating system for the Microfilm tube to generate flash steam that is used in the syrup pre-cooker. This lowers the overall steam requirement for the Microfilm cooker and reduces energy losses from the condensate as it returns to the boiler.
