Stop relying on the “feel” of skilled workers! With one machine, the quality of vinegar rice will always remain stable

In 2026, the sushi industry as a whole is collectively facing an unseen but severe test. Costs continue to rise like a shadow, labor costs have become unaffordable, while consumers’ demands for quality and stability have never waned. Efficiency improvement is no longer an option for development; it has become a survival necessity. In this efficiency revolution sweeping across the industry, astute operators have begun to shift their focus from the front stage to the backstage, onto those fundamental yet crucial preparation processes – that is, the mixing of vinegar rice.

What seems like a simple mixture of vinegar rice is actually the foundation and soul of sushi flavor. Therefore, Koyama Kojiro has launched a professional sushi vinegar mixing machine, using the machine to replace manual labor, and mixing out stable, uniform and delicious vinegar rice in every bucket.

Stir evenly, and make each grain of rice evenly coated with vinegar.
The core of the equipment is equipped with a bionic wrist mixing system, which precisely simulates the flipping, chopping force and rhythm of skilled workers. It ensures that the vinegar liquid and rice can be evenly mixed within a short period of time, eliminating the problems such as local over-acidity, clumping or uneven taste that may occur in manual mixing. This guarantees that every mouthful of vinegar rice meets the top standard of “clearly granular and deliciously sweet and sour”.

Built-in cooling function. No waiting required. Just mix and use immediately.
The most time-consuming part of making vinegar rice is not the mixing itself, but waiting for it to cool down. The traditional natural cooling process takes a very long time, which not only slows down the serving speed but also causes the flavor and texture of the rice to gradually deteriorate during the waiting period.

The Koyama Kyouju vinegar mixer is equipped with a powerful synchronous cooling function, which enables quick and even cooling while the ingredients are being mixed. There is no need for long waiting time. Once the vinegar rice is taken out of the machine, it can be used immediately to make sushi. This not only significantly reduces the preparation time, allowing you to respond quickly to orders even during peak periods, but also locks in the best luster and elasticity of the rice, ensuring that every dish produced is at its flavor peak.

With just one click, even beginners can make master-level vinegar rice.

During operation, simply add the steamed rice and the prepared vinegar, and press the start button. The machine will automatically complete all subsequent steps. This significantly reduces the reliance on the operator’s experience and ensures absolute consistency in the quality of the products. Whether it’s a new store opening or personnel changes, the core flavor remains stable as before.

Two options, tailored to your different scales

Restaurants of different sizes have varying requirements. Yozueta’s vinegar mixer offers two models, providing you with a tailor-made solution:

1.Desktop vinegar mixer
Designed specifically for single stores or small chain operations with a focus on space efficiency and high performance. It is compact in size but does not compromise on functionality. It can complete the standardized preparation of 6 kilograms of vinegar rice in just 6 minutes, which is sufficient to flexibly cope with daily operations and lunch and dinner peak periods. It is a reliable partner for improving kitchen efficiency and strengthening the quality foundation.

2.Floor-standing Vinegar Mixing Machine
Targeted at medium and large chain brands or scenarios requiring large-scale production. It has stronger power and a larger capacity. In just 6 minutes, the vinegar mixing volume increases to 16 kilograms. Its powerful continuous operation capability can provide stable, efficient, and uniform vinegar rice output for the store.

In 2026, the competition in the sushi catering industry has reached the level of optimizing every production process. The Shinozawa Kyouji Smart Vinegar Mixer is a professional solution that emerged at this critical juncture. It uses technology to enhance traditional techniques, converting uncertainty into controllable standards and transforming time costs into competitive efficiency.
