Energy efficiency: the devil's in the details

Supplier: Hurll Nu-Way By: Olga Kustova

Hurll Nu-Way supplies equipment helping food manufacturers to save energy and become more sustainable.

While air compressors are widely used in food industry for packaging, product sorting, cleaning, peeling, dehydrating, blow-off and other applications, compressed air needs a lot of energy and it has to be clean and oil-free.

Hitachi oil free scroll compressors answer these needs, possessing energy saving features, such as multi drive control mode, allowing energy savings by operating in modulating compressor heads mode. Suitable for ISO 14001 factories, equipped with compressed air dryers and filters, they deliver contaminant free air required by the industry specifications.

Product losses, caused by cleaning out of place (COP) process, can be eliminated with help of Mouvex pumps, possessing ability to clear the pipes through its CIP ability. No seals means no leaks, and with reduced maintenance, this pump is a great product and time saver. It also consumes less energy using smaller motors and operating at reduced speed.

Process heating necessary for food preparation is a highly energy consuming process. To use less energy for heating, the heating element should be as close to the product, as possible, and immersion tank heating is a great solution.

The small diameter heating tube elements are located in the heating tank, and provide great efficiency and low operating costs, saving the distribution losses associated with steam. 

Operating efficiency is higher than 80 per cent of gross calorific value and fuel cost savings are approximately 30-50 per cent when compared to the central boiler and electrical heating alternatives. Lanemark immersion tube burners are used in breweries for hot water heating and wort boiling, for blanching vegetables, frying snack foods, in animal scalders, and for cleaning in place tanks.

Any food processing generates waste, and to be sustainable, the companies should use this waste rather than dispose of it. The simple solution is using the process of anaerobic digestion to turn waste into power that can be used for heating or cogeneration.

Proper anaerobic digestion mixing systems will guarantee higher biogas yield while Utile vane compressors for digester gas mixing would further contribute to low maintenance and energy saving system.
