ultrasonic cake cutting——Water chestnut cake

Water chestnut cake is a traditional dessert snack in Suzhou City, Jiangsu Province, Guangzhou City, Guangdong Province, Fuzhou City, Fujian Province, and Nanning City, Guangxi. It is said that it originated in the Tang Dynasty. It is steamed with sugar water mixed with water chestnut powder or sweet potato powder. Water chestnut, also known as Mati in Cantonese and Fujian, hence its name. Its color is tea yellow, semi transparent, foldable without cracking, pouting continuously, soft, smooth, refreshing, and tough, with an extremely fragrant and sweet taste. The taste is sweet, and it melts right into the mouth.

The principle of ultrasonic cutting machine is to use ultrasonic vibration to generate surface vibration and thermal energy, which will locally heat and melt or vibrate the cut material, thereby achieving the purpose of cutting. So, ultrasonic cutting does not require sharp edges, nor does it require significant pressure, and will not cause edge collapse or damage to the material being cut. At the same time, due to the ultrasonic vibration of the cutting blade, the frictional resistance is particularly small, and the material being cut is not easy to stick to the blade. This is particularly effective for cutting sticky and elastic materials, frozen materials such as food, rubber, or objects that are not easily pressurized.
