Testing

 

 

Testing in-house

 

Most new applications for IR drying are tested in some way. At the Ircon workshop in Vänersborg it is possible to carry out certain preliminary tests on different types of test equipment. As part of the testing programme, we can vary the power heating time and the type of IR lamp.

Different types of lamp can generate varying amounts of energy at different radiation wavelengths and this can have an effect on the heating result.

Testing at customer location

 

Ircon has a total of 40 different types of dryer to meet the needs of most its customers. The dryers are usually installed in existing paper and coating machines to provide proof of moisture removal or to document other process parameters. The dryers can usually be switched to different positions if required. Power is typically 24 to 75 kW for each dryer. Heated widths are 150, 300 or 450 mm although wider dryers are also available.

 

 

 

Testing in pilot coaters

 

Ircon dryers are installed in several modern pilot coaters. Some are for public use and some are owned by the mill and used for in-house development. Below are two examples:

 

 

Styron pilot coater, Switzerland

This coater has eight Ircon electric IR dryers at different locations. The coater can run at up to 3000 m/min. 

 

 

 

 

UMV Coating Systems pilot coater

This coater can run at up to 2200 m/min and has a total of 15 Ircon electric IR frames at two locations. The coater is used for UMV customer trials.

Testing at SP

 

For our customers in the food processing field, we work closely with SP Food and Bioscience. At the SP location in Gothenburg we have several IR pilot ovens as well as microwave ovens. They are designed to be flexible and a number of them can be transported to the customer. The pilot ovens can be used for drying and heating trials as well as baking trials.

Testing at Micvac

 

Microwave heating of ready-cooked food is tested at the Micvac facility in Gothenburg.
