Description

Technical Field

[0001] The invention relates to the technical field of fish feed processing, in particular to a straw feed processing center and a processing method for aquaculture. Background Art

[0002] Straw feed mainly refers to fiber feed made from crushed sweet sorghum, corn, reed, cotton and other straws. It is the main feed for ruminants. Currently, fish feed is mostly made of grain powder, such as bean cake and bran. At present, adding straw powder to the main ingredients can greatly reduce feed costs. Unlike ruminants, fish ponds will have water plants and silt and other substances. If the feed is not attractive enough to fish, fish will eat water plants and silt and other substances. Therefore, some auxiliary materials such as bone meal, salt, licorice, etc. are added during the production of fish feed to attract fish to eat and avoid malnutrition caused by fish picky eating. For example, the Chinese invention patent with authorization announcement number CN103892113A discloses a compound straw fish feed formula and a preparation method thereof, which discloses a preparation method. The raw materials for preparing the active ingredient include rice straw powder, 50-80 parts of red potato vine powder, 15-25 parts of corn flour, 10-15 parts of bean cake, 10-15 parts of bran, 10-15 parts of bone meal, 5-8 parts of tangerine peel, 5-8 parts of mulberry leaves, 5-8 parts of licorice, 2-5 parts of yeast powder, and 0.5-1 parts of salt. This straw-based fish feed is generally made by a feed pellet machine to make a pelletized feed that is easy for fish to eat in water, but has the following defects during processing:

[0003] Before pelleting, the raw materials need to be mixed and tempered, mainly by heating to mature the raw materials. Since fish feed contains a small amount of conditioning auxiliary materials, these auxiliary materials are easy to clump during conditioning and mixing, and are difficult to break up, resulting in uneven distribution, which ultimately causes uneven content in pellet feed. Some pellet feeds do not contain conditioning auxiliary materials, which cannot attract fish to eat, and easily lead to fish picky eating.

[0004] To this end, we propose a straw feed processing center and a processing method for aquaculture to solve the above problems. Summary of the invention

After being cut by the cutting knife 16, it is formed into a short rod style, and then it is torn by two crushing rollers 17 to form straw powder; the straw powder obtained in step 1 enters the modulation bin 22 in the tempering and mixing mechanism 2 through the conveyor line, and at the same time, the grain powder is also added to the tempering and mixing mechanism 2, and the mixture of bone meal and seasoning is loaded into the silo 44, and then the second servo reduction motor 28 is started to drive the two screw belts 26 to rotate to mix the materials, and the electric heater 230 is started for heating, and at the same time, the spreading component 4 in the auxiliary material feeding structure 3 reciprocates to evenly spread the mixture of bone meal and seasoning and mix it with the materials; after preliminary mixing for 5-8 minutes, the steam supply device 214 is started to pass into the modulation bin 22 Steam, lasting 4-6 minutes, completes the maturation and tempering, and obtains the maturation material; the pneumatic push rod 226 is started to lift one end of the modulation bin 22, so that the maturation material is discharged from the inlet and outlet 231, and enters the conveyor line, and is conveyed to the granulator 5, and the finished feed pellets are obtained after being pressed and cut; the present invention is provided with a special auxiliary material discharge structure 3 for the discharge of seasoning auxiliary materials, instead of adding the seasoning auxiliary materials and the main materials into the machine for mixing at the same time. During the tempering, under the action of the reciprocating screw 37, the spreading component 4 carrying the seasoning auxiliary materials will reciprocate, and at the same time, the rotating drum 42 and the unloading auger plate 43 rotate to drop the seasoning auxiliary materials downward, and the third gear 416 rotates under the action of the outer gear ring 413, so that the paddle 415 rotates to break up the fallen seasoning auxiliary materials, so that the seasoning auxiliary materials are evenly scattered, so that the spreading area is larger, the agglomeration of the seasoning auxiliary materials is avoided, and the final pellet feed content is ensured to be uniform.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
