Description

RELATED APPLICATIONS This application claims priority to Taiwan Application Serial Number 111144059, filed Nov. 17, 2022, the disclosures of which are incorporated herein by reference in their entireties. TECHNICAL FIELD The present disclosure relates to a food inspection device. More particularly, the present disclosure relates to an automatic food inspection device. BACKGROUND With the increasing progress of society, the quality of people life is also improving day by day. With the improvement of modern people's living conditions, tasting high-quality food has become an important part of life. Taking coffee as an example, coffee has become a very important beverage in modern people's daily lives. The unique coffee flavor depends on the selection of coffee beans and the roasting technology of the barista. Different temperatures and roasting times may bring different tastes to the coffee. The quality of the coffee is starting from the selection of coffee beans, and a traditional method of selecting coffee beans is manual selection to remove defects in the coffee beans. With the increasing advancement of science and technology, machines are used to screen defective products such as beans, such as coffee beans, or grains, and are also widely used in large food factories or businesses. However, for specialty coffee lovers and small quantities of roasted coffee demanders, there is a need to be able to provide a convenient and accurate screening device for beans, such as coffee beans, or grains.
