[0002] Raisins are a food made by dehydrating grapes with the help of solar heat or artificial heating. They are high in sugar and are a typical high-energy nutritional product. Raisins have a low water content and are easy to transport and store. The most important dried grapes around the world are the green seedless grape variety Seedless White. Other dried varieties include White Rose and Black Corinth. During the production process of raisins, the grape stems need to be removed to ensure that they are more convenient to eat later. There are many types of stem removal equipment, and the functions of them are constantly increasing, making them more convenient to use.

[0003] The existing methods of removing raisins stems mainly include beating, sieve roller and kneading. The most commonly used method for removing raisins stems is kneading, which can not only remove stems quickly and in large quantities, but also ensure the integrity of the raisins.
