What is the Induction Heating used in Hotaru?
Hotaru combines Induction Heating (IH) with its UMAI advanced fuzzy logic processor to provide precise control over the cooking process and consistently excellent rice.
What Is Induction Heating?
Induction Heating (IH) works by using a magnetic field to generate heat directly within the inner cooking bowl.
Inside Hotaru are induction coils that generate a rapidly changing magnetic field when the cooker is switched on. The specially designed inner bowl responds to this magnetic field and generates heat itself, rather than relying solely on a conventional heating element underneath the bowl.
This means that the inner cooking bowl effectively becomes the heat source.
The IH system can apply heat rapidly and make very fine adjustments throughout the cooking cycle, providing responsive temperature control from high heat through to more precise lower-temperature adjustments.
More Even, Responsive Cooking
Because heat is generated directly within the inner bowl, IH technology can provide more even heat distribution and highly responsive temperature control compared with conventional heating systems.
This helps Hotaru manage the cooking process more precisely, contributing to:
More even cooking
Consistent rice texture
Better control of cooking temperatures
Efficient heat transfer
Enhanced flavour and overall rice quality
IH technology works particularly well when combined with advanced fuzzy logic because the cooker can rapidly adjust the heat in response to what is happening inside the bowl.
UMAI Fuzzy Logic – The Brain of Hotaru
Hotaru also features a UMAI Fuzzy Logic processor, which acts as the "brain" of the rice cooker.
Rather than simply switching the heating element on and off at predetermined points, the fuzzy logic processor monitors information from the cooker’s thermal sensors and uses that information to make adjustments to the cooking process.
It can automatically adjust factors such as:
Temperature
Cooking time
Heating intensity
The progression through different stages of the cooking programme
This allows Hotaru to respond to what is actually happening inside the cooking bowl rather than simply following a rigid, fixed sequence.
IH + Fuzzy Logic
The combination of IH heating and UMAI fuzzy logic is what makes Hotaru particularly sophisticated.
The IH system provides the ability to apply heat rapidly and precisely, while the fuzzy logic processor determines how and when that heat should be applied.
Together, these technologies allow Hotaru to carefully manage the cooking conditions for different types of rice and different cooking programmes.
Multiple Cooking Programmes
The UMAI fuzzy logic system also allows Hotaru to use dedicated programmes for different foods and rice varieties, including:
White rice
Long-grain rice
Short-grain rice
Brown rice
Yumami
GABA
Rice porridge
Oat porridge
Each programme can use its own carefully controlled combination of temperatures, cooking times and cooking stages to suit the food being prepared.
A Smarter Way to Cook Rice
A basic cooker can essentially turn heating on and off according to a simple temperature threshold. Hotaru takes this much further.
Its UMAI fuzzy logic processor continually interprets the information provided by the thermal sensors and makes small adjustments to the cooking process, while its IH system delivers the heat quickly and precisely.
The result is a highly responsive cooking system designed to make great rice consistently, while giving you dedicated programmes for different rice varieties and dishes.
