Embodiment 1

[0014] Embodiment 1: A kind of production method of complete small-diameter aquatic product hard pellet feed, comprises the following steps: 1. mix the feed formulation raw materials that do not contain synthetic hormones, synthetic binders, and antibiotics according to the formula ratio, and pulverize to 0.02mm; ② Add 18% flour to the mixed powder; ③ Add steam to the mixed powder to soften the material so that the moisture content reaches 12% to form a hot and humid material; A compression mold with a hole diameter ratio of 20:1; ⑤ Feed the hot and humid materials into the molding machine to make granules with a diameter of 0.8mm; Use a grading sieve to remove broken grains and powder; ⑧ Pack the complete small-diameter hard aquatic pellet feed into the warehouse.

Embodiment 2

[0015] Embodiment 2: A production method of a complete small-diameter aquatic hard pellet feed includes the following steps: ① mixing the raw materials required for the feed according to the formula ratio, and crushing to 0.30mm; ② adding 25% of the total weight to the mixed powder ③Add steam to soften the material in the mixed powder, so that the weight content of moisture reaches 18%, forming a hot and humid material; Send it into the molding machine to make granules with a diameter of 1.2mm; ⑥ After keeping the granules warm for 50 minutes, cool the temperature to 40°C with cold air; Aquatic hard pellet feed is packaged and put into storage.

Embodiment 3

[0016] Embodiment 3: A kind of production method of complete small-diameter aquatic product hard granular feed comprises the following steps: ① Mix the formulation raw materials of the feed in proportion, and grind to 0.25mm; ② Add 22% of the total weight to the mixed powder Flour; ③ Add steam to the mixed powder to soften the material so that the moisture content reaches 15% to form a hot and humid material; ④ Use a die with a die hole depth to diameter ratio of 25:1; ⑤ Feed the hot and humid material into the molding In the machine, granules with a diameter of 1.0mm are made; ⑥ After keeping the granules warm for 40 minutes, the cold air cools down to 35°C; The feed is packaged and put into storage.

Abstract

The invention discloses a production method for a complete minor diameter hard particle aquatic feed, which comprises the following steps: 1. the raw materials is mixed and crushed into 0.02 to 0.30mm in proportion; 2. the flour with a weight content of 18% to 30 percent is added into the mixed powder lot; 3. a steam softening materials is added into the mixed powder lot so as to make the weight content of moisture reach 12 percent to 18 percent, thereby the moist heat materials is formed; 4. a die mold with the ratio between the depth and the diameter of die hole of 20:1-28:1 is adopted; 5.the moist heat materials is delivered into a forming machine to produce the particles with a diameter of 0.8 to 1.2 mm; 6. after the heat preservation for 20 to 50 min, the particles are cooled to 28 DEG C to 40 DEG C by cold wind; 7. the crushed grain and powder of cooling particle feed are filtered by a grading screen; 8. the complete minor diameter hard particle aquatic feed is packed and stored. The minor diameter hard particle aquatic feed which is made by the method of the invention has the advantages that: the utilization rate is high; the need of feed of the fish and shrimp larvae can be met, and the waste of feed can be reduced; furthermore, the pollution of the quality of the cultivation is reduced, and the balance of nutriment for the fish and shrimp larvae is improved.

Description

technical field [0001] The invention relates to a processing method of aquatic feed, in particular to a method of making complete small-diameter aquatic hard particle compound feed which uses various fish and shrimp larvae as feeding objects. Background technique [0002] In the process of intensive fish and shrimp farming, when the larvae change from eating natural bait or microencapsulated feed to eating hard pellet compound feed, the size of the hard pellet feed needs to match the length of the larvae to improve feed utilization and ensure fish Shrimp get balanced nutrients. The existing small hard pellet feed manufacturing process generally adopts the secondary molding method of making large pellets first and then crushing them into small pellets. The resulting small hard pellet feed has obvious differences in size, irregular shape, more powder, and low utilization rate. Contents of the invention [0003] The technical problem to be solved by the present invention is ...
