Description

Technical Field

[0001] This invention belongs to the field of aquaculture feed technology, specifically a premixed feed for abalone and its production process. Background Technology

[0002] In recent years, abalone farming has developed rapidly as a highly nutritious aquatic product. To meet the rapidly increasing nutritional needs of abalone, the addition of premixes has become crucial for improving farming efficiency and abalone quality. Traditional abalone premix production processes typically include steps such as drying, crushing, mixing, and granulation of raw materials, but these methods have limitations in protecting the nutrients and active substances in the raw materials.

[0003] Existing drying technologies, such as hot air drying, often lead to the loss of heat-sensitive components like vitamins and proteins. Furthermore, traditional pulverization methods may generate excessive heat during processing, further affecting the stability of nutrients in the raw materials. High-temperature drying during granulation can also cause nutrient degradation. Therefore, there is significant room for improvement in existing technologies regarding the maintenance of nutrient stability in raw materials. Summary of the Invention

[0004] The purpose of this invention is to provide an improved abalone premix and its production process, which not only improves the nutritional value and safety of the product, but also has good environmental and economic benefits, providing an efficient and sustainable feed solution for the abalone farming industry.

[0005] The technical solution adopted in this invention is as follows:

[0006] a) Raw material pretreatment: The raw materials are dried using drying technology;

[0007] b) Crushing process: The dried raw materials are crushed to a specific particle size using ultrasonic-assisted crushing, which helps to break the materials without raising the temperature;

[0008] c) Mixing: Mix the pulverized raw materials; add an appropriate amount of water during the later stage of mixing and continue stirring to form a wet mixture;

[0009] d) Dry again; the wet mixture is dried again.

[0010] e) Grind into powder, and then grind the dried mixture into powder again;

[0011] (b) In this step, the dried raw material is placed in an ultrasonic pulverizer, and the ultrasonic frequency is adjusted to 20 kHz to 40 kHz; ultrasonic treatment is started and lasts for 5 to 15 minutes; the cavitation effect generated by the ultrasonic waves helps to break down the structure of the raw material and achieve the pulverization effect; the particle size of the pulverized raw material is 0.1 mm to 0.4 mm.

[0012] c) In this step, the mixing time is 15 to 20 minutes;

[0013] The raw materials comprise, per kilogram:

[0014] Vitamin A acetate ≥700,000 IU, nicotinamide ≥1,500 mg, thiamine nitrate ≥500 mg, folic acid ≥230 mg, riboflavin ≥800 mg, inositol ≥5,000 mg, pyridoxine hydrochloride ≥1,500 mg, iron ≥3,500 mg, cyanocobalamin ≥1.0 mg, magnesium ≥800 mg, vitamin D3 ≥250,000 IU, cobalt ≥50 mg, dl-α-tocopherol acetate ≥4,500 mg, nicotinamide menadione bisulfite ≥650 mg; protease: ≥800 mg, polysaccharides oligosaccharides ≥200 mg, acidifier ≥1,000 mg, probiotics ≥100 million CFU, antioxidant ≥500 mg, garlic powder ≥200 mg, and curcumin ≥200 mg.

[0015] The abalone premix has a moisture content of ≤10% and uses rice husk powder and zeolite powder as carriers.

[0016] The iron in the formula comes from ferrous sulfate monohydrate; magnesium comes from magnesium sulfate monohydrate; cobalt comes from cobalt sulfate monohydrate; the acidifier is citric acid; the probiotic is Lactobacillus acidophilus; and the antioxidant is vitamin C or vitamin E.

[0017] In step c), mixing is performed using a premixing device, which includes a vertically arranged hollow tube. The horizontal cross-section of the hollow tube is a regular polygon. A vertically arranged main shaft is fitted inside the hollow tube at intervals. A main motor drives the main shaft to rotate. Multiple large bevel gears are fixedly fitted on the main shaft at intervals along its length. Multiple stirring shafts are horizontally distributed around the large bevel gears. One end of each stirring shaft rotates through the hollow tube and has a small bevel gear fixed at its end. The small bevel gears mesh with the large bevel gears. The other end of each stirring shaft rotates through a horizontal stirring drum. A first stirring blade is provided on the outer circumference of the stirring shaft. Multiple vertically fixed support columns are evenly distributed around the hollow tube. The other end of the horizontal stirring drum is rotatably supported on the support columns via a short shaft. A sub-motor fixed on the support columns can drive the horizontal stirring drum to rotate via the short shaft. The horizontal stirring drum includes a lower drum and an upper cover. The lower cylinder is a horizontal hollow cylinder with a flattened and open upper part; the upper cover is an arc-shaped cover with an open lower end; the lower end of the upper cover is detachably fitted to the upper end of the lower cylinder; the upper end of the upper cover is an elastically stretchable surface; a deformable stirring linkage assembly is installed inside the upper cover; a connecting head is rotatably installed at the center of the elastically stretchable surface, passing through it; rotatable telescopic rods are respectively installed below the horizontal stirring cylinder; when the motor drives the horizontal stirring cylinder to rotate 180 degrees, the connecting head aligns downward with the rotatable telescopic rod; after the rotatable telescopic rod extends and aligns with the connecting head, it pulls back, pulling the elastically stretchable surface down into a cone-like shape; during the downward pulling of the elastically stretchable surface, the deformable stirring linkage assembly simultaneously unfolds into an inverted triangular frame structure in the vertical direction; after the rotatable telescopic rod pulls the elastically stretchable surface down, it drives the unfolded inverted triangular deformable stirring linkage assembly to rotate through the connecting head.

[0018] The deformable stirring linkage assembly includes a long rod, two short rods, and two middle rods. One end of each middle rod is hinged to the side of the docking linkage head located inside the upper cover, and the other end is hinged to one end of each short rod. The other end of each short rod is hinged to the end of the long rod, so that the deformable stirring linkage assembly is generally a rectangular frame structure in its normal state. A hydraulic telescopic rod is connected between the docking linkage head and the middle of the long rod. The hydraulic telescopic rod can drive the deformable stirring linkage assembly to unfold into a triangular frame structure. Second stirring blades are respectively provided on the long rod and the middle rods.

[0019] The docking linkage head and the end of the rotatable telescopic rod are provided with a snap-fit ​​linkage structure. The snap-fit ​​linkage structure includes a vertical groove opened along the axial direction of either the docking linkage head or the rotatable telescopic rod and a horizontal groove opened along the circumferential surface. The vertical groove and the horizontal groove are connected to form an L-shaped groove. Multiple sets of L-shaped grooves are arranged around the circumferential surface, and an interference block is arranged on another L-shaped groove. When the rotatable telescopic rod extends, the interference block slides into the vertical groove, and further slides into the horizontal groove when the rotatable telescopic rod rotates, realizing dual linkage of rotation linkage and axial tension linkage.

[0020] The elastic stretchable surface is provided with a material inlet near the docking linkage head for pumping material into or out of the horizontal mixing drum.

[0021] The number of faces of the hollow tube corresponds to the number of horizontal stirring drums in each layer.

[0022] The mixing method of the premix mixing device is as follows:

[0023] ① Pump the premixed material into the horizontal mixing drum through the feed port. At this time, the upper cover is located at the top of the horizontal mixing drum.

[0024] ② The controller controls the main motor to drive the main shaft to rotate. The main shaft drives the stirring shaft to rotate through the large bevel gear and the small bevel gear, thereby horizontally stirring the premix.

[0025] ③ After the horizontal mixing reaches a certain level, the controller controls the sub-motor to drive the horizontal mixing drum to rotate 180 degrees through the short shaft, so that the upper box cover faces downwards; the controller controls the rotatable telescopic rod to extend and connect with the docking linkage head; after docking, it pulls back to pull the elastic stretchable surface down into a cone-like shape; at the same time, the deformable mixing linkage group unfolds into an inverted triangular frame; the premixed material falls into the cone-like body under the action of gravity; then water is added into the horizontal mixing drum (43) through the material port;

[0026] ④ The controller controls the rotation of the rotatable telescopic rod, which drives the deformable stirring linkage assembly to rotate in a cone-shaped stirring motion through the docking linkage head;

[0027] ⑤ After mixing is complete, the premixed material is extracted through the feed inlet.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. The abalone premix and its production process of the present invention have several significant beneficial effects:

The process of the mixing device switching between these two forms perfectly matches step c) in which the pulverized raw materials are mixed; an appropriate amount of water is added in the later stage of mixing to continue stirring and form a wet mixture; therefore, it can achieve efficient and high-quality mixing results.

[0063] Space efficiency: The hollow tube design of this invention enables multiple horizontal mixing drums to be stirred simultaneously by a single main shaft, optimizing space utilization and allowing the mixing equipment to achieve three-dimensional multi-stage stirring within a limited space.
