Full Automatic Dorayaki Machine
KAISHINDO adopted a Full Automatic Dorayaki Machine (capable of producing 850 pieces per hour) in 2006. In 2017, they replaced it with a higher production model capable of 1600 pieces per hour.
The machine produces traditional dorayaki with moist pancakes with a nice texture filled with a lot of red bean paste. It is popular as dorayaki made by a yokan manufacturer and its production volume is increasing every year.
-
Dorayaki has three flavors: apple, ogura, sesame. The apple flavor uses the local Esashi apples.
-
Before adopting the machine, KAISHINDO manufactured dorayaki with a copper sheet pan. After the adoption of a Full Automatic Dorayaki Machine, they have been producing without changing the formula and are happy about it.

The Full Automatic Dorayaki Machine in operation. In order to recreate the old method of baking, there is no heat from the top. Instead, the pancake is flipped to cook both sides.
-
After being baked, dorayaki goes through the cooling tunnel to be cooled hygienically. It also saves some space.
-
At the time of replacement, KAISHINDO adopted double depositors and created space to put additional toppings like chestnut, to simplify future product development.
-
The Sandwich Machine can be taken apart to clean. KAISHINDO has replacement parts prepared nearby, ready to replace at any time, even during production.
