Siroca to Release 5L Large Capacity 'Ouchi Chef Cooker' Featuring Simultaneous Cooking for Main and Side Dishes

Siroca Inc. (Chiyoda-ku, Tokyo) is set to launch the 5L model of its 'Ouchi Chef Cooker' on May 28 and June 18, 2026. This automated cooker allows users to perform pressure and steam cooking efficiently without compromising on flavor.

Designed to meet the needs of larger households and families with children, the new 5L size supports cooking for 4 to 6 people. It features industry-leading high pressure of 100kPa and 'Shun-kan Healthy Steam' technology for rapid steaming. A standout feature of the 5L model is the included 'Simultaneous Cooking Container,' which enables the preparation of two different dishes—such as a main and a side, or rice and curry—at the same time.

Equipped with proprietary 'Smart Pressure Technology,' the device maintains constant high pressure to make ingredients exceptionally tender while utilizing an automatic decompression function to shorten overall cooking time. Furthermore, the inner pot now uses a ceramic coating instead of fluororesin to align with environmental conservation goals. With the time-saving mode, 3 cups of white rice can be cooked in approximately 22 minutes.
