How is fish feed processed? Processing of fish feed additives

Take aquatic feed as an example.

Due to the physiology and dietary habits of aquatic animals such as fish, shrimp and crabs, aquatic feed is required to have good water resistance, low pulverization rate, fine raw materials, and neat feed cuts. According to these requirements, after years of exploration and research, we have fully ensured the quality of products, lower energy consumption, less labor, and achieved an increase in revenue.

Raw material. Raw materials are the source of feed production. Mainly: corn, wheat bran, secondary meal, fish meal, cake meal after oil extraction of various oil crops (such as soybean meal, rapeseed meal, etc.). All food processing by-products can be used as feed.

Clean. Bulk grains received from farms typically include grain by-products and impurities such as straw, stones, metal, paper, wood chips, small animal carcasses, and powder. The cleaning operation is to remove these impurities with equipment and systems such as magnets, screens, dust collectors, etc., to ensure that the stored grain is of good quality and to protect the machine during the subsequent processing steps.

Smash. Crushing is an operation to reduce the particle size of the feed and increase its specific surface area, which can enhance the digestion capacity of the animal, improve the utilization rate of the feed, and also improve the processing quality and work efficiency of the subsequent process steps such as batching, mixing, and pelleting.

Ingredient. The batching and mixing process refers to the combination of bulk dry raw materials and liquid raw materials into a homogeneous mixture with added value.

Mix. <>

Molasses added. Refers to the scale-up, addition and mixing of dry and/or liquid trace elements and premixes to form a complete feed mixture, i.e. a formulated diet.

Granulation. Extrusion refers to the process by which moist, expandable starch or protein material is plasticized in a tube by a combination of moisture, pressure, heat, and machinery. This results in an increase in the temperature of the product inside the tube, gelatinization of the starch components, denaturation of the proteins, stretching or recombination of the tactile components, and exothermic expansion of the extruds.

In the submersible feed process, the treated feed pellets enter the pelleting equipment and are compressed into pellets by means of rollers and dies in the pelleting chamber.

Cooling. In the feed pelleting process, the cooling of the feed pellets is essential. When leaving the pellet mill, the feed pellets are very hot, soft and rich in moisture, and the cooling process cools them to just over room temperature of 3 - 5 and reduces their moisture content to safe standards for easy transport and storage.

Screening. After cooling and drying, the whole pellet or extrudate is sieved to remove fines and spills so that the pellets reach a qualified size.

Wrap. The packaging operation starts from the finished feed enters the ** box above the packager and ends when the bagged feed is placed in the warehouse. The procedure includes weighing each bag of feed, placing the weighed items in the bag, closing the bag mouth, labeling the bag, coding the bag, palletizing the bag, and moving the bag to the warehouse for storage.

Fodder.

Fish feed is the same as other pellet feed, according to the formula of the raw materials crushed and mixed evenly, and then through extrusion granulation, the specific process can be. In addition, in order to prevent the fish feed from falling loose immediately after entering the water, some starch, clay, grease and other starch will be added for waterproof bonding.

Summary. The preparation method of described fish feed additive comprises the following steps:

1) Preparation of anti-stress activating components: Yang lotus and Maoyan berry are chopped and mixed to obtain a mixture, each time the weight of the above mixture is added 3-5 times of deionized water, ultrasonic, extracted 2-3 times, each time the extract is taken, the extract of the above 2-3 times is combined, concentrated to the original volume of 10-15, and the anti-stress activating components are prepared;

2) Preparation of food-promoting ingredients: bracken and lettuce are blanched in boiling water for 5-7min and then drained, vacuum dried, and the dried bracken and Ulva are made into dry powder with a particle size of 70-80 mesh and mixed well to prepare food-promoting ingredients;

3) preparation of fish feed additives: the food-promoting ingredient, flavoring powder and valerian root extract prepared in step (2) are added to the anti-stress activating ingredient prepared in step (1), after stirring and mixing, vacuum drying, crushing, sterilization, and the fish feed additive is prepared.

Fish feed is generally made from rice bran, bran, soybean cake, fish meal, barley, yeast meal, straw meal, corn meal, sweet potato rattan powder, green fodder and other ingredients. Different flavors of fish need to be prepared according to different fish species. Fish commonly used grandchildren answer feed formula:

Bran, fish meal, soybean cake, barley, green fodder. The main raw materials of fish include imported fishmeal, soybean grains, crude fiber, vitamins, corn, etc.

Fish can be earthworms, diced raw meat, leeches, dough, fish eyes, fish intestines, rice grains, shrimp, meat maggots, corn bugs, chewing gum, water bugs, grasshoppers, small fish, and chicken intestines as bait.

The adaptability of bait is very wide, some are first-class bait, and some are Puze Huitong bait. Therefore, only by comparing and screening the bait can we get a good harvest.

The feed of the aquarium is mainly divided into: floating feed, sinking feed, pellet feed, and flake feed. Floating Feed:

Suitable for top fish or big fish. Submerged feed: suitable for bottom fish, snails and shrimps.

Flake feed: It can take into account the upper, middle and lower tropical fish, and is more inclined to middle and upper fish.

1) Plant green fodder. At present, the more common green fodder planted are ryegrass, Sudan grass, alfalfa, clover, etc., and the yield of grass per mu can reach 5 tons and 10 tons. There is great potential for growing green fodder fish farming.

2) Make the most of various by-products. Including agricultural and sideline products are adapted to areas with large water surface and abundant by-product resources. This kind of feed includes bran, rattan, seedlings, etc., which are crushed or processed into pellet feed; Industrial by-products such as brewer's grains, soy sauce residues, powder residues and non-staple food scraps such as vermicelli factories and starch factories are precipitated and dried after slurry protein powder.

3) Supporting the establishment of small feed mills. It is suitable for intensive aquaculture in fishing grounds with large water surface and high level of intensive culture. By planting green fodder and using by-product fish farming, we can make full use of the resource advantages to reduce the cost of farming.

2. What are the commonly used energy feeds for fish farming: energy feed accounts for 40%-50% of fish feed. Energy feed is mainly cereals such as corn, barley, wheat, rice, etc., and their processing by-products such as rice bran, bran, secondary flour, etc.

Energy feed generally has a high digestibility and can reach more than 50%. Lower than protein feed**. However, its nutrient content is single, mainly soluble sugars and starches, so it cannot be used as fish feed alone.

It is more suitable to use this type of feed to process fish feed. On the one hand, it provides energy, on the other hand, it can also be used as a binder for processing pellet feed, especially for the production of extruded pellet feed, which can increase the flavor and improve palatability.

3. What are the commonly used mineral feeds: The main role of mineral feed is to provide macromineral elements for fish. Mainly calcium, phosphorus, sodium, chlorine, etc.

The main types of mineral wheel feed used are as follows: (1) Bone mealBone meal provides phosphorus and calcium. Due to its different processing methods, it can be divided into three types: steamed bone meal, raw bone meal, and bone char powder.

Steamed bone meal is commonly used as feed. Due to processing problems, organic matter is attached to the surface of bone meal, which causes pollution and affects its quality.

2) Dicalcium phosphate. Dicalcium phosphate mainly provides phosphorus, with a phosphorus content of 14%-16% and its utilization rate is high, and dicalcium phosphate is mostly used as a phosphorus source in fish feed. It is worth noting that the fluoride content of calcium diphosphate is too high due to lax beneficiation and defluoride measures, which will adversely affect the growth of fish.

The state stipulates that the fluoride content of calcium diphosphate does not exceed 0 18%. 3) Stone powder and shell powder. Both stone powder and shell powder provide calcium, of which the calcium content can reach more than 35%.

4) Table salt. Table salt is rich in sodium and chloride, which are generally lacking in plant-based feeds. Therefore, it should be supplemented in the feed.

In addition, the addition of table salt can promote appetite and help sensitive digestion.

1. Palatability, fish feed is more palatable after processing, and it is convenient for fish to eat.

2.Convenient storage is not delayed, because the fresh macro vertical live feed is not resistant to storage, so the production of feed can be stored for a long time.

3.Balanced nutrition, by making fish feed, the protein content in the feed can be made in line with the growth of fish, and the problem of a single nutrient component of a certain bait can be solved.
