Bradshaw develops non-stick microwave inserts

Somerset-based cooking equipment supplier Bradshaw has created a non-stick cavity liner that can be used within high powered microwaves such as the Menumaster brand in its portfolio.

The new Esi-Clene microwave cavity protector consists of a liner and a Teflon-coated sheet for the oven door. The product is said to facilitate cleaning and extend the life of microwave ovens.

“Other cavity liners are used for lower powered microwaves and use plastic materials in their construction,” detailed Bradshaw’s sales manager, John Marks. “When we looked at these systems, we recognised that for the very heavy use that Menumaster units are designed for, and the higher powers that Menumaster has available for faster heating, an exhaustive series of trials would be required to ensure the safety and reliability of the products.

“An extensive testing programme of ‘food safe’ grade plastics revealed that under heavy duty usage, the plastics softened, distorted and in certain cases melted releasing some of the chemicals contained in the plastics. This was not unexpected as microwaves are often used to heat similar plastics past their softening points to enable vacuum forming. For this reason, we decided to look for an alternative solution that did not rely on plastics to deliver the ease of cleaning that equipment users request.”

The resulting Esi-Clene is designed to operate up to 270°C, and is said to be wipe clean or can be washed in a dishwasher.
