Infrared Heat in Food Processing Applications

The food processing industry benefits greatly from infrared technology. Infrared systems have found use in a number of areas.

Infrared in food processing applications

For food industries, infrared modules are manufactured in stainless steel and fitted with a wire mesh to afford mechanical protection. Infrared heaters from Heraeus are very responsive and can be switched on and off within 1-2 seconds. All infrared systems can be controlled so that any unexpected or unwanted conveyor belt stoppage will have minimal effect on the equipment or product. Heater failure detection is also incorporated within the control system.

Infrared heat provides a particularly efficient and reliable solution for many heating processes in the food industry, including:

IR is disinfecting bread

Mould spores are naturally present within a bakery environment and contamination can take place as the bread cools before it is wrapped. Heraeus have now carried out successful tests, both in their Neston Applications Centre and on-site, at various bakeries, to demonstrate the effectiveness of Infrared as a mould-prevention technology.

IR browning ready meals

Carbon infrared is ideal for applications in the food industry, such as surface browning, as it delivers medium wave infrared radiation, which is perfectly suited to evaporating water from products, at a very high power density. This ensures that the surface of the food product rapidly achieves a sufficient temperature to drive away any local moisture and then cause browning without any possibility of after-cooking.

IR is preheating moulds for chocolates

A precisely-controllable, two-zone carbon infrared heating system from Heraeus Noblelight is helping to ensure consistent chocolate quality at Ashbury Chocolates Ltd, of Corby, by pre-heating chocolate moulds prior to filling.

Jars are preheated with Infrared

A purpose-built carbon infrared oven has been instrumental in allowing Duerr’s of Manchester to change from a hot water rinse system to a cold air rinse system at their Wythenshawe jam-making site.
