The company’s commitment to maximizing the value of food resources is deeply rooted in the founder’s experience of food shortages. Making the most of limited resources and eliminating waste has become a core corporate value that has been passed down through generations. This philosophy extends beyond simply utilizing every part of the raw material, influencing daily operational efforts to ensure stable supply, reduce losses, and improve efficiency. The company also places a strong emphasis on collaboration with its business partners, promoting the development of a sustainable supply chain through the effective use of by-products generated after oil extraction.
To support this vision, Tsuno Group has established a robust manufacturing foundation capable of consistently reproducing high product quality. By minimizing losses associated with operational downtime, the company ensures a stable supply of products that contributes directly to customer satisfaction.
For example, bran suppliers. By further processing the by-products generated after oil extraction into valuable products and supplying them back to our partners, we are helping to create a more sustainable supply chain.

💡 Tip: Did you know? A simple way to elevate your everyday rice.
Just add 1/2 teaspoon of rice bran oil for every 2 cups of rice before cooking. The result is fluffy, glossy rice with beautifully separated grains. Because rice bran oil has a clean, neutral flavor, it gently coats each grain and helps retain moisture, enhancing both texture and appearance without altering the natural taste of the rice. The cooking process stays exactly the same. All it takes is a single spoonful.
Rice bran oil is not only ideal for frying and sautéing,
it can also subtly enhance your everyday meals.
That's another one of the many appealing ways to enjoy rice bran oil.
Alfa Laval’s Unique Mechanical Seal Technology Contributes to Consistent Product Quality
One of the key advantages of using Alfa Laval centrifuges, according to Mr. Hayashi of the Engineering Department at Tsuno Group Co., Ltd., is their advanced functionality.
“The mechanical seal (hermetic design), a distinctive feature of Alfa Laval centrifuges, minimizes contact with air during processing. Because oil is highly susceptible to the effects of air exposure, we believe this feature contributes significantly to maintaining consistent product quality.”
For Tsuno Group, where quality is carefully built into every stage of the manufacturing process, such design features are indispensable both for quality management that ensures product safety and reliability, and for maintaining a stable supply of products.
After-Sales Service: The Core of Preventive Maintenance Supporting Stable Operations
|
At Tsuno Group Co., Ltd., production downtime is viewed not merely as a cost, but as a loss of valuable resources. As a result, maintaining stable operations is regarded as one of the company's highest priorities. In a manufacturing environment focused on maximizing uptime, capital investment decisions are increasingly evaluated based on their contribution to operational reliability. The company positions after-sales service as a core component of its preventive maintenance strategy for sustaining stable operations. Intermediate maintenance is conducted every three months, while major maintenance is carried out annually. Through these scheduled maintenance activities, equipment performance and condition are systematically managed to build a strong foundation for reliable operations. Rather than waiting to repair equipment after a problem occurs, the company embraces a proactive approach focused on preventing downtime before it happens. Critical spare parts with long procurement lead times are secured in advance, helping minimize the risk of unexpected shutdowns. At the same time, while prioritizing the prevention of equipment stoppages, the company has also established systems and processes designed to address unforeseen circumstances. The key is to never regard trouble as truly “unexpected.” When issues do arise, they are addressed quickly and effectively through well-defined coordination and support frameworks that have already been put in place. |
Reflecting on this approach, Mr. Kimura of the Engineering Department commented: What impressed me most was how quickly Alfa Laval’s service team responded whenever an issue arose. By working closely together from an early stage, we have been able to resolve problems quickly and effectively |
