Description

Sea oyster sheller and its method of use

technical field

The invention relates to a sea oyster shell skidding machine and a method thereof.

Background technique

The most critical part of the deep processing of sea oysters lies in the aspect of shelling and extracting meat. China’s research on deep processing of sea oysters started relatively late compared with foreign countries, and its research and development capabilities in aquatic product production and processing equipment are also much weaker than foreign countries. Most of them are still Stagnated at the stage of theoretical research, many major advanced processing and production equipment still rely on imports. The main breeding grounds of sea oysters in China are in some coastal cities, most of which still use the most traditional manual method to open the shells or open the shells naturally after being cooked. However, sometimes the quality of sea oysters obtained by manually opening the shells is poor, and it is more laborious to manually hit the crowbar. Opening the shell again will destroy the fresh and tender taste of the sea oyster and cause the loss of the sea oyster's nutritional content. For this reason, need a kind of sea oyster shell skidding machine.
