[0002] Peanut kernel refers to the part without the shell, which is actually the seed of the peanut. The whole peanut is called the fruit or pod. It is also called peanut rice, ground peanut, ground fruit, and Chinese bean. Peanuts are good for nourishing and can prolong life, so they are also called "longevity fruit" by the people. Like soybeans, they are also known as "vegetable meat" and "vegetarian meat". The nutritional value of peanuts is higher than that of grains and can be comparable to eggs.
[0003] Peanut kernels are divided into two types: unified grade peanut kernels and hand-picked peanut kernels. Hand-picked peanut kernels are further divided into graded and ungraded. Their quality specifications are specifically stipulated in the foreign trade contract, and the results are inspected and evaluated according to the items stipulated in the contract. The existing grading and screening equipment transports the peanut kernels to the sieve plate for vibration screening. Several sieve plates are set up according to the number of levels of screening required.
