Chitin (Chitin), also known as Chitin, was found in 1811 by the french scholar blakenor (Braconno), and was extracted from crustacean shells in 1823 by oegill (0dier) and named Chitin, which is translated as Chitin. Chitin is the second largest biological resource which is second to cellulose in quantity in nature, and is estimated to be biosynthesized by 100 hundred million tons every year, is one of the most abundant organic matters on the earth, is an inexhaustible biological resource for human beings, and is one of natural resources which are not fully utilized in the 20 th century, wherein the marine organism generation quantity reaches 10 hundred million tons. Chitin has anticancer, cancer and tumor cell metastasis inhibiting, immunity improving, liver protecting, and toxic materials clearing away effects. Is especially suitable for diabetes, liver and kidney diseases, hypertension, obesity, etc., and is favorable to preventing cancer cytopathy and assisting radiotherapy and chemotherapy in treating tumor. The chitin is chemically inactive, does not change with body fluid, does not react with foreign matters in tissues, is nontoxic, and has the characteristics of thrombus resistance, high-temperature disinfection resistance and the like. Chitin is widely existed in shells of shrimps and crabs of crustacean of arthropoda, is a nitrogen-containing natural organic compound with the largest quantity except protein on earth, and is widely applied to food production, medicines, industries and the like.

The extraction equipment of chitin using shrimp shells as raw materials as claimed in claim 1, wherein the outside of two support columns (551) is opened with a chute (554), the slide carriage (555) is located inside the chute (554), and the length of the smoothing brush (557) is the same as the length of the conveyor belt (51).

4. The chitin extracting device using the shrimp shells as raw materials as claimed in claim 1, wherein a second motor (558) is fixedly installed on one side of the top of the drying box (53), a power driving end of the second motor (558) is connected with a screw rod (553), a second feeding hopper (68) is fixedly installed on the top of the crushing box (62), a blocking plate (69) is fixedly installed on the outer side of the second feeding hopper (68), a second discharging port (610) is fixedly installed on the bottom of the crushing box (62), and one end of the outer side of the second discharging port (610) extends to the interior of the shrimp shell collecting box (8).

5. A method for extracting chitin by taking shrimp shells as raw materials is characterized by comprising the following steps:

clear water is put into a water storage tank (48), then an auger (3) is started, prepared shrimp shells are poured into a feeding pocket of the auger (3), and finally fall into a cleaning barrel (42) from a first feeding hopper (413), a water pump (41) and a first motor (43) are started at the moment, water in the water storage tank (48) passes through a water inlet pipe (410) and a first water outlet pipe (49) under the action of the water pump (41), and finally enters the cleaning barrel (42), a power driving end of the first motor (43) drives a stirring roller (44) to rotate, so that stirring blades (45) are driven to rotate synchronously, the internal shrimp shells are stirred, cleaning is more uniform, and when soft hairs (47) on two sides of the stirring blades (45) are contacted with the shrimp shells, cleaning cleanliness is improved, and sanitation and safety of the shrimp shells are guaranteed;

after the cleaning is finished, a first valve (412) is opened, dirty water is discharged from the inside of a second water outlet pipe (411), then a buckle (416) is opened, the shrimp shells in the shrimp shells fall to the upper end of a conveyor belt (51), for the shrimp shells which are not completely discharged, only a first motor (43) needs to be started again, the shrimp shells are stirred down under the action of a stirring blade (45), at the moment, the conveyor belt (51), a heating plate (54) and a second motor (558) are started, clean shrimp shells enter the drying box (53) under the action of the conveyor belt (51), a baffle plate (52) prevents the shrimp shells from falling down, the internal temperature rises under the action of the heating plate (54), the moisture on the surfaces of the shrimp shells is evaporated, at the moment, the height between a telescopic rod (556) and the shrimp shells is adjusted until a position where a flattening brush (557) is in contact with the shrimp shells, then under the action of the second motor (558), the lead screw (553) is driven to rotate, the slide seat (555) is synchronously driven to reciprocate in the chute (554), and finally the flattening brush (557) is driven to reciprocate in the drying box (53) to flatten the shrimp shells, so that the drying speed of the shrimp shells is increased;

when the dried shrimp shells reach the tail part of the drying box (53), the dried shrimp shells fall into the second feeding hopper (68) from the first discharging port (57), at the moment, the third motor (65) is started, the power driving end of the third motor (65) drives the driving wheel (66) to rotate, under the action of the belt (67), the driven wheel (64) is synchronously driven to rotate, so that the crushing roller shaft (63) is driven to rotate, the shrimp shells in the shrimp shells are crushed, and the crushed shrimp shells directly fall into the shrimp shell collecting box (8) from the second discharging port (610);

after the crushing is finished, the second valve (11) is opened, the extracting solution in the extracting solution storage barrel (7) falls into the shrimp shell collecting box (8) from the liquid outlet pipe (10), when a certain amount of the extracting solution is reached, the second valve (11) is closed, the shrimp shells are soaked for 24 hours, and finally, the centrifugal equipment is used for drying water, the internal materials are dried, and the chitin dried product is obtained.
