What is KAEN Solid Fuel?
KAEN is a premium Solid Fuel from Japan that functions as a portable food warmer. This product is a modern solution replacing liquid spirits or conventional paraffin wax which are often smelly and risky to spill.
As the HORECA standard food warmer, KAEN is ideal for lighting chafing dishes (buffet warmers) in hotels or shabu-shabu pots in Japanese restaurants.
Why is KAEN the Best Choice for Your Business?
- Preserved Food Quality (Odorless & Smokeless): Combustion with KAEN produces no smoke and no odor on the food. This guarantees the original taste and aroma of your dish remains perfectly preserved.
- Practical & Long Lasting: The flame produced is very stable with a burning time 2 times longer than ordinary gel products. KAEN is also available in various sizes to suit the heating duration you need.
- Cost Effective & Efficient: Very easy usage and easy-to-clean combustion residue make your operations more efficient.
- Adds Aesthetic Value: The clean and consistent blue flame makes live cooking dishes like hotpot or shabu-shabu look more professional and luxurious to customers.
- Safe for Indoor Use: Specially designed for indoor use (hotels and restaurants) with high safety standards (non-explosive).
