Description

Technical Field

[0001] The invention relates to the technical field of feed fermentation processing, in particular to a mud crab feed mixing fermentation device. Background Art

[0002] In the blue crab farming industry, the quality and nutritional content of feed are directly related to the growth rate, health status and final market value of blue crabs. Blue crabs are high-protein, low-fat aquatic products, and their demand for feed is not only reflected in macronutrients such as protein and fat, but also includes micronutrients such as various vitamins, enzymes, hormones, and trace elements. These ingredients play an indispensable role in promoting digestion and absorption of blue crabs, enhancing immunity, and promoting growth.

[0003] When configuring mud crab feed, it is necessary not only to focus on its protein demand, mineral and trace element demand, but also its palatability and digestibility. Specifically, in terms of protein demand, mud crabs, as high-protein organisms, have a large demand for protein. Therefore, when formulating mud crab feed, special attention will be paid to the source and content of protein to ensure that mud crabs can obtain sufficient protein supply; in terms of mineral and trace element demand, mud crabs also have a strong demand for minerals such as calcium and phosphorus, as well as trace elements such as zinc and iron. These components play an important role in the bone development, shell formation and physiological functions of mud crabs. In the formula of mud crab feed, special attention will be paid to the content and proportion of these minerals and trace elements; in terms of palatability and digestibility, in order to ensure that mud crabs can fully ingest and utilize the nutrients in the feed, the feed formula will consider the palatability and digestibility of the raw materials.

[0004] Blue crab feed fermentation can improve the nutritional value of feed, enhance the palatability of feed, promote intestinal health, and better meet the nutritional needs of blue crabs, enhance the immunity and disease resistance of blue crabs, reduce the incidence of diseases, and thus improve the survival rate and yield of breeding. At present, the feed required for blue crabs is mainly composed of the following raw materials: solid raw materials such as fish meal, shrimp and its by-products (such as shrimp head powder, shrimp roe), shellfish (such as oysters, snails), green feed (such as Chinese cabbage), soybean meal or puffed soybean meal; vitamin mixture (including vitamin A, D, E, B group, etc.), mineral mixture (including calcium, phosphorus, zinc, iron and other trace elements). When preparing blue crab feed, the above raw materials need to be processed and fermented with fermentation agents (such as yeast), enzyme preparations, etc. Usually, the vitamin mixture, mineral mixture, and fermentation agent are mixed with water into liquid raw materials and added to the solid raw materials, and then the solid raw materials are mixed with the liquid raw materials for subsequent feed fermentation. In the existing preparation process, when completing the above work, the staff needs to process the raw materials in sequence, and there is still room for improvement in feed quality and timeliness.

[0017] Beneficial effects of the present invention:

[0018] 1.

When the first rotating column rotates one circle, the solid raw material in the storage box can be added to the upper part of the grinding disk in the device cylinder through the feeding hopper.

[0020] 3. By setting up a stirring mechanism, the rotation of the drum can drive the stirring rod and the air outlet pipe to rotate and stir the feed inside the fermentation box, so that the feed is mixed more evenly and fully, and the stirring rod can rotate while rotating around the drum. When the two stirring rods rotate, the bite action of the crushing teeth can be used to break up the lumps produced during mixing in the feed, thereby reducing the formation of lumps.

[0021] 4. By setting up a pressing mechanism, when the solid raw material enters the device barrel, the pressing plate can press on the solid raw material, exerting downward pressure on the solid raw material, so that the solid raw material can be ground more quickly and efficiently.

[0022] 5. By setting up a liquid adding mechanism, when the solid raw materials fall after being ground, as the amount of solid raw materials above the grinding disc decreases, the pressure plate moves downward and the connecting plate moves downward. The second piston rod is pressed downward by the downward movement of the connecting plate, and the liquid raw materials temporarily stored in the second piston cylinder are squeezed out and added to the fermentation box through the liquid outlet pipe. This can realize the gradual addition of liquid raw materials, avoid the problem of agglomeration when a large amount of liquid raw materials is added at one time, and ensure the subsequent good fermentation effect of the feed.

[0023] The present invention can realize the integrated operation of automatic adding, mixing and fermentation of solid raw materials and liquid raw materials during the fermentation processing of blue crab feed, thereby greatly improving the efficiency and effect of the fermentation processing of blue crab feed.

[0042] Mixing pretreatment process before fermentation:

[0043] When the present invention is used, it is necessary to first add the solid raw material into the storage box 6, and add the liquid raw material into the liquid storage box 9, and then it is necessary to press the first piston rod 17 once so that the second piston cylinder 18 is filled with the liquid raw material, and then the feed mixing operation before fermentation is carried out, and the second electric telescopic rod 8 is started to extend. When the second electric telescopic rod 8 is extended, it can drive the connecting plate 7 to move upward, and when the connecting plate 7 moves upward, it can drive the pressing plate 25 to move upward through the vertical rod 19.

[0044] Then, the second electric telescopic rod 8 is started to retract, and the tension of the tension spring 21 acts on the vertical rod 19, so that the vertical rod 19 moves downward, and the connecting plate 7 is driven downward by the vertical rod 19, so that the pressing plate 25 can press on the solid raw material, generating downward pressure on the solid raw material, so that the solid raw material can be ground more quickly and efficiently;

[0045] Start the motor 41 to drive the second gear 42 to rotate. Since the second gear 42 is meshed with the third gear 43, the rotating rod 44 can be driven to rotate, and the connecting sleeve 48 can be driven to rotate by the rotating rod 44. When the connecting sleeve 48 is inserted into the slot 40, the grinding disc 35 can be driven to rotate, and the solid raw materials inside the device cylinder 2 can be continuously ground, so that the solid raw materials are broken into pieces and enter the fermentation box 1 through the leakage groove 38. In the process of the solid raw materials falling after grinding, as the amount of solid raw materials above the grinding disc 35 decreases, the pressing plate 25 moves downward, and the connecting plate 7 moves downward. The second piston rod 33 is pressed downward by the downward movement of the connecting plate 7, and the liquid raw materials temporarily stored in the second piston cylinder 18 are squeezed out and added to the fermentation box 1 through the liquid outlet pipe 53, so that the liquid raw materials can be gradually added.

[0046] When the rotating rod 44 rotates, it can drive the rotating drum 45 to rotate. Through the rotation of the rotating drum 45, the stirring rod 57 and the air outlet pipe 56 can be driven to rotate to stir the feed inside the fermentation box 1, so that the feed is mixed more evenly and fully. While the stirring rod 57 rotates circumferentially around the rotating drum 45 along with the rotating drum 45, the fifth gear 60 is engaged with the sixth gear 61, driving one of the stirring rods 57 to rotate. Since the two fourth gears 59 are engaged, the two stirring rods 57 can be synchronously rotated. When the two stirring rods 57 rotate, the bite action of the crushing teeth 58 can be used to break up the lumps generated during the mixing of the feed, thereby reducing the formation of lumps.

[0047] Fermentation process:

[0048] When the solid raw material is ground, the pressing plate 25 moves to the extreme downward position, and the movable rod 46 is squeezed downward by the pressing plate 25. When the movable rod 46 moves downward, the connecting sleeve 48 can be pushed out of the slot 40, and then the connecting sleeve 48 will not drive the grinding disc 35 when it rotates, so that during the subsequent feed fermentation, the grinding disc 35 will not be driven to rotate, but only the rotating drum 45 will be driven to rotate. Oxygen can be introduced into the feed inside the fermentation box 1 through the air outlet pipe 56 to meet the needs of feed fermentation, and fermentation is carried out under predetermined temperature and humidity conditions. Usually, the fermentation temperature should be controlled between 30°C and 40°C, and the humidity should be maintained at a predetermined level. During the fermentation process, the fermentation situation is checked regularly, and the feed can be discharged through the discharge valve 14 after the fermentation is completed.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
