With the completion of the new Sano Factory, they replaced two oven lines. The long lines are laid out in a way that makes them easy to operate. NAKAYAMASEIKA produces a variety of baked sweets using these lines such as Russian Cake with a long shelf life of 180 days as well as tarts.
Russian Cake line
Two ovens are incorporated in the Russian Cake line. NAKAYAMASEIKA’s signature product, Russian Cake has six variations with different batter and shapes. The production of each variation is switched around depending on the day. With this replacement, more rows have been added, and the production volume has increased by about 1.2 times. Furthermore, replacing the filling depositing equipment that is used after baking increased the accuracy greatly.
