[0002] Earthworm protein is extracted from earthworms and contains collagenase, plasmin, lumbrokinase, fibrinolytic activator protein, nucleic acid, trace elements and other components. Its molecular weight is 5000-10000 and it is a short-chain small molecule. Earthworm extract is extracted from earthworms through high-tech, and earthworm protein tablets, earthworm protein soft capsules, fibrinolytic activator protein and other products have been successfully developed.

[0017] A method for continuous extraction of earthworm protein comprises the following steps:

[0018] S1. Wash the selected earthworms with clean water to remove mud, sand, impurities and internal organs. During the washing process, attention should be paid to maintaining environmental hygiene to avoid secondary pollution. After washing, the earthworms should be dried;

[0019] S2, adding the washed and dried earthworms to an appropriate amount of enzymatic hydrolysis solution, controlling the temperature at 45-50°C during the enzymatic hydrolysis process, the enzymatic hydrolysis time at 2-5 hours, and the pH at 7.8-8.0 to ensure the enzymatic hydrolysis effect, filtering the enzymatic hydrolysis solution through a filter to remove solid residues, and obtaining a lumbar protein peptide extract;

[0020] S3, feeding the earthworm protein peptide extract into the centrifuge barrel 2 inside the box through the feed port 105 for centrifugation, and centrifuging at a speed of 8000-12000 r / min for 10-18 min;

[0021] S4, the earthworm protein peptide extract will be stratified after centrifugation, and the supernatant on the upper surface of the earthworm protein peptide extract can be extracted through the discharge pipe 301 to ensure that only pure earthworm protein peptide extract is left in the centrifugal barrel 2, and then discharged through the discharge port 202 at the bottom;

[0022] S5. Collect the pure earthworm protein peptide extract obtained above, concentrate and dry it, the concentration method is low temperature concentration, the drying method is spray drying, and finally vacuum packing is performed.

[0023] Working principle: When in use, the staff will feed the earthworm protein peptide extract that has been preliminarily treated into the box body 1 through the feed port 105. The earthworm protein peptide extract will first pass through the filter plate 401 at the upper end of the inner side. Under the action of the filter hole, the impurities in the earthworm protein peptide extract can be filtered to ensure the quality of the extraction. The filtered earthworm protein peptide extract can enter the centrifugal barrel 2 through the guide plates 5 on both sides. At this time, the internal motor 6 starts to drive the rotating rod 602 and the gear 1 603 to rotate, and under the meshing action, it can drive the internal gear 2 604 to rotate. Since the centrifugal barrel 2 is rotatably installed inside the box body 1 through the discharge port 202 at the bottom, it can rotate with the gear 2 604 to centrifuge the internal earthworm protein peptide extract. The centrifugal operation stops after 10-18 minutes of centrifugation. At this time, the earthworm protein peptide extract will be layered;

[0024] When processing the stratification, the cylinder 304 is started to drive the connecting plate 303 and the discharge pipe 301 to move toward the inside of the centrifugal barrel 2, so that the port of the discharge pipe 301 can contact the bottom surface of the supernatant above the earth dragon protein peptide extract. At this time, the pump body 302 is started to extract the supernatant outward through the discharge pipe 301, thereby ensuring that the pure earth dragon protein peptide extract remains in the centrifugal barrel 2, and the pure extraction operation of the earth dragon protein is completed;

[0025] The filter plate 401 may be blocked during use. At this time, when the staff disassembles it, they only need to press the push plate 403. Under the relative rotation of the two rotating shafts, the connecting block 408 slides inside the slide groove 4010, and in the process of pressing inward, the two connecting blocks 408 slide to the outermost end of the slide groove 4010. At this time, the positioning block 4011 is disengaged from the inside of the positioning hole 4013 and cannot provide a snap-on effect. The staff can directly pull the filter plate 401 upwards to remove it. When installing, repeat the above steps. After the filter plate 401 enters the inside of the mounting member 4, the push plate 403 is reset under the action of the spring 404, completing its snap-on installation and improving the filtering effect of the device.

[0026] (III) Beneficial effects

[0027] The present invention provides a device for continuous extraction of earthworm protein, which has the following beneficial effects:

[0028] 1. The present invention first performs enzymolysis on earthworms to ensure the extraction effect, and a centrifugal bucket is arranged inside the box to cooperate with a gear assembly to perform centrifugal extraction on earthworm protein peptide extract, and a filter plate is arranged in the middle of the centrifugal bucket and the feed port to filter impurities inside the earthworm protein peptide extract to ensure the quality of the earthworm protein peptide extract during extraction. After the centrifugal extraction is completed, the discharge pipe can be adjusted under the action of the cylinder to automatically discharge the supernatant, thereby achieving the effect of rapid and continuous extraction;

[0029] 2. The filter assembly inside the present invention can be disassembled and assembled under the action of the limit assembly and the positioning assembly, which is convenient for replacing filter plates of different mesh sizes and prevents the filter plates from being blocked, thereby improving the filtering effect of the entire device.
