What is the Hotaru inner bowl made from?
Through our many years of selling Zojirushi rice cookers, we noticed that rice cookers available across the UK, Europe and USA predominantly used Teflon or similar non-stick coatings on their inner cooking bowls.
After receiving extensive feedback and questions from customers about inner-bowl materials, we decided to develop a different approach for our premium rice cookers.
The result is our Joubu inner bowl, which features a durable 3mm-thick ceramic coating designed to provide a hard-wearing cooking surface while avoiding conventional PTFE-based non-stick coatings.
What Makes the Joubu Bowl Different?
The Joubu bowl has been designed with both cooking performance and everyday usability in mind.
It features:
3mm-thick ceramic coating
BPA-free
PTFE-free
PFAS-free, including PFOA and PFOS
A hard-wearing cooking surface
A special honeycomb structure to help distribute heat evenly
Silk-printed rice measurement lines that are designed to be durable and easy to read
Designed for Even Heat Distribution
The inner surface of the Joubu bowl incorporates a special honeycomb structure designed to help disperse heat more evenly across the bowl.
Even heat distribution is particularly important when cooking rice, as it helps provide consistent cooking throughout the bowl and reduces the potential for localised hot spots.
This is especially beneficial when combined with Hotaru's Induction Heating (IH) system, where the bowl itself becomes the heat source.
Durable, Easy-to-Read Measurement Lines
We've also considered the smaller details that make a difference when using a rice cooker every day.
The rice measurement lines on the Joubu bowl are silk printed rather than stamped. This provides clearly visible markings that are designed to be hard wearing while remaining easy to read, even in lower-light conditions.
Accurate water measurement is an important part of achieving consistent rice, so having clear measurement markings directly inside the bowl makes preparation easier.
A Premium Alternative to Conventional Non-Stick Bowls
The Joubu bowl was developed in response to customer feedback and our desire to provide a premium ceramic-coated alternative to the conventional non-stick bowls commonly found in rice cookers.
With its 3mm ceramic coating, hard-wearing construction, heat-distributing honeycomb structure and durable measurement markings, Joubu is designed to provide a combination of cooking performance, durability and ease of use.
Joubu is another example of how we use our years of experience selling and developing rice cookers to focus on the features and materials that matter to our customers.
