Overview

Microwave ovens are ideally suited for drying:

• Newly made moulds.
• Wet moulds after de-moulding.
• Conditioning filled moulds prior to de-moulding.
• Piece drying.

Features & Benefits

• Up to 80% reduction in drying times when compared to conventional hot air drying ovens.
• Up to 25% reduction in energy consumption when compared to conventional hot air drying.
• In-line processing.
• Number of moulds reduced by 60%.
• Moulds last 4-5 times longer.
• Uses ‘shop air’ to remove moisture.
• Microwaves ‘moisture level’ the product by differential heating.

Moisture Levelling by Differential Heating

• In the case of ceramics and fireclay, the base material, when dry, absorbs very little microwave energy.
• The wetter parts will absorb more energy and dry faster.
• This differential heating effect will continue until the moisture content is substantially even through out the product.
• This assists varying thickness’s of section to dry more evenly.
• You can mix and match varying shape items with differing water content within the same oven. i.e. back slabs, dividers, and sinks.
