With a remarkable portfolio of 72 patents, his innovations focus primarily on methods and devices aimed at enhancing food preparation processes, particularly in the production of dough and bread.

Latest Patents

Hayashi's recent patents showcase his inventive prowess. One of his notable inventions is the "Apparatus for rolling food dough." This invention provides a sophisticated method and apparatus designed to roll food dough without causing any slipping between the dough and the rolling rollers. It prevents twisted shrinkages in the dough, ensuring a smooth rolling process. The apparatus features a cradle that adjusts its height in relation to a table and includes conical-shaped rolling rollers that are rotatably mounted. The design allows the rollers to swivel, ensuring that the speed of rotation increases during use compared to passive rotation. Additionally, the method controls the descent speed of the rollers, which decreases gradually from the initial speed.

Another significant innovation by Hayashi is the "Apparatus and method for manufacturing a loaf of bread." This invention details a comprehensive process that begins with a forming step to create a sheet from a block of bread dough. The subsequent steps include forming a bar-like dough, cutting this dough into pieces, and strategically placing these pieces into a baking mold with one cutting plane facing upward. This innovative method ensures that any air bubbles trapped between layers of dough can escape during fermentation and baking, leading to a perfectly risen loaf.
