Abstract
Description
Technical field:
[0002] The utility model relates to an oyster shelling device. Background technology:
[0004] China is the world's largest producer of oysters and a major importer and exporter. In terms of oyster production, China's oyster production accounted for 83.29% of the world's total in 2017, reaching 5.1398 million tons in 2018, and reached a new high of 5.2256 million tons in 2019, accounting for 38.51% of the world's total production. China's oyster production is mainly concentrated in Fujian, Guangdong, Shandong, Guangxi and Liaoning. Currently, oysters farmed in Fujian Province are large in scale and high in output, and 90% of their products need to be shelled and sold. However, the existing key oyster processing process, shelling and peeling, is mainly based on the production method of rough processing workshops, and the processing equipment lacks mechanization. These factors have seriously restricted the key factors in the development of the oyster industry.
