Crab shell crushing and extracting device

Abstract

The invention discloses a crab shell crushing and extracting device. The crab shell crushing and extracting device comprises a shell of a hollow structure and is characterized in that the upper-side lateral wall of the shell is provided with a feeding inlet, the lateral wall on one side of the shell is provided with a mounting cavity and a first drive motor, the output shaft of the first drive motor penetrates the shell and the lateral wall of the mounting cavity and is connected with a transverse first rotary shaft, one side, away from the first drive motor, of the first rotary shaft is provided with a first belt wheel, a second belt wheel is rotatably connected into the mounting cavity through a transverse second rotary shaft, the first belt wheel and the second belt wheel are connectedthrough a belt, and one side, away from the second belt wheel, of the second rotary shaft penetrates the lateral wall of the mounting cavity and is connected with a transverse first gear. The crab shell crushing and extracting device has the advantages that crab shells can be sufficiently crushed in a large-batch manner, pure chitin can be extracted by the aid of an extracting agent, and time andlabor can be saved.

Description

Technical field [0001] The invention relates to the technical field of chemical extraction, in particular to a crab shell crushing and extraction device. Background technique [0002] Crabs are delicious, rich in nutrients, and are loved by people. The shells of crabs contain chitin, which has anti-cancer, inhibiting cancer and tumor cell metastasis, improving human immunity and protecting liver and detoxification. It is especially suitable for diabetes, liver and kidney disease, hypertension, obesity, etc. It is beneficial to prevent cancer cell pathology and adjuvant radiotherapy and chemotherapy to treat tumor diseases. Natural chitin needs to be extracted from the shells of crustaceans, and crab shells are rich in chitin, so the extraction of crab shells has become the focus. However, crab shells are hard and have thorns, which brings certain inconvenience to breaking. Moreover, the degree of crushing directly affects the subsequent extraction of chitin from crab shells, whi...

Problems solved by technology

Natural chitin needs to be extracted from the shells of crustaceans, and crab shells are rich in chitin, so the extraction of crab shells has become the focus. However, crab shells are hard and have spikes, which bring some inconvenience to breaking. Moreover, the degree of crushing directly affects the subsequent extraction of chitin from crab shells, which brings certain difficulties to batch crushing of crab shells and extraction of chitin, which is time-consuming and labor-intensive.
