What is superheated steam?
Superheated steam is a colorless, transparent vapor created by heating saturated vapor evaporated at 100°C to an even higher temperature. This technology is also used in home appliances such as steam ovens.
Superheated steaming mechanism
Water vapor with a temperature of 100°C or higher is created using high-frequency induction heating with zero direct CO2 emissions.
1) Reduce food waste by extending the shelf life of food products (Real-world example: superheated steam roasting of coffee beans)
2) Drying food residue for recycling (Real-world example: superheated steam drying of used coffee grounds)

Usage Example 1: Rotating Kiln Method
Superheated steam is fed into the inside of the kiln, heating the material while rotating it. The processing time can be set, making it possible to adjust the amount of time of the superheated steam irradiation (cooking/roasting). It can also be attached to a kiln you currently use.
Usage Example 2: Drop Separation Method
Superheated steam and material (mainly grains) are fed in from the top of the machine, and the workpieces are processed as they fall. This method is well-suited for sterilizing grains such as rice and buckwheat seeds, and the short processing time has little effect on their taste.
Usage Example 3: Cyclone Method
Superheated steam and material (mainly powder) are fed in from the top of the machine, and the workpieces are processed as they fall. After processing, a cyclone is used to separate and recover the superheated steam and the material (powder). This method can be used for sterilization of rice bran and other such materials, and has a proven track record of use for commercialization.
