With the rapid development of the aquaculture industry, traditional farming methods have far from satisfying people’s needs, and the requirements for the aquatic feed are not only equalized nutrition, but the stability of feed in water is good, and the animal survives The quality of the environment – the quality of the water makes a stricter requirement. The production process of aquatic puffed feed and the traditional livestock feed production process has a large difference according to the variety of the aquatic feed, the raw materials change, the fineness of the crushing requirements is high and the fluidity of the material is characterized, and the production process is generally used. Secondary crushing and secondary ingredient mixing, then the processing of aquatic puffed feed is completed by puffing, drying, outer spraying, cooling, crushing and screening.

1 Raw Material Cleanup and Coarse Coarse
RQE China Feed Industry Information Network – Bit Feed , Serving animal husbandry The raw materials used in the feed mill generally have two forms: one is a powder, they don’t need to be crude. For this raw material, it can directly pass the lower material. After the hoist, enter the conical cleaning screen to remove the tapered cleaning screen, then the magnetic separator or the spiral twinkle directly enters the distribution bin, participate in the first ingredient; the other is A coarse-pulverized material is required. This material is subjected to the low-pit, and the hoist enters the cleaning equipment to perform the debris selective processing, and then enter the warehouse to be pulverized, then after the crushing machine is crude, then the lifting machine, the dispenser enters the bunker to participate in the first ingredient . For individual raw materials, such as shrimp shells, may not pass through the primary cleaning, and directly pass the magnetic selection into the warehouse to be pulverized. A crude pulverization is the pre-microclinating processes in aquatic feed processing. Its main purpose is to reduce the particle size difference and variation of materials, improve the working conditions of the ultrafine pulverizer, improve the work efficiency of ultrafine pulverizer and ensure The product quality is stable; at the same time, in order to improve workers’ work environments, reduce cross-contamination, it is recommended to use independent dustproof nets, that is, the drum is used to adopt an independent dust removal system.

The first ingredient is mainly formulated by mass raw materials, that is, in the formulation, a relatively large material formulation. This process is mainly completed by an electronic batch scale. However, in the first ingredient process, it is necessary to pay special attention to the fringe problem of the distribution bin, which is mainly due to the reasons for the material of the aquatic feed, especially the weight of the high-grade aquatic feed material, and the difference in the fluidity of the material. Therefore, the ingredients should be taken to take certain anti-knot measures, such as eccentric unloading, vibrating motor, and the like. The first mixing can be used for uniaxial horizontal screw mixers, and the grease adding system must be considered on the mixer. The first ingredients are also equallyIt is the pre-treatment process of ultrafine pulverization, which is mainly to reduce the range of variations in material granularity, improve the working conditions of the pulverizer and improve the working efficiency of the pulverizer, and ensure the quality of the product.

3 Double Crush and Secondary Ingredients RQE China Feed Industry Information Network – Based Feed, service animal husbandry
Due to the low food production capacity, short digestive tract, poor digestive ability, so the aquatic feed requires that the particle size of the smash is very fine, to increase the surface area of u200bu200bthe feed, increase the aquatic animal The contact area of u200bu200bdigestive fluid and feed increases the digestivity and feed remuneration of the feed of the feed; and also due to the low intake of the aquatic products, the mixing uniformity of the feed can be reflected in a smaller range, which also requires Aquatic feed has a finer particle size.

Microscopy now is generally used in aquatic feed process, and a strong wind pick is equipped with a strong wind pickup and then entering a rotational classification screen. The purpose of configuring the rotational hierarchical screen here is mainly to remove the fine velvet hair formed by the crude fibers in the feed, because the presence of these fine fluff is easily adhered to the mold hole of the expander, until the mold hole is blocked, resulting Stop cleaning, so you must clear it.

The secondary ingredients and mixed were performed. Since the fineness of the material of the secondary ingredient mix is u200bu200b60 more than 60 mesh, and the density is small, it should be paid to the arch. In order to eliminate this phenomenon, an eccentricity can be used in an aspect, and all the ultra-smashabed material outlets are used in an impeller feeder, which is not only a false architecture, but also can be flexible to regulate flow. the size of. Various raw materials have entered a secondary mixer after passing the quadratic ingredients. An artificial feed port is provided above the secondary mixer, mainly used for the addition of micro additives, and is provided with a liquid addition mechanism on the mixer, which is used for the addition of grease; 1 is for water addition. During the second mixing process, various materials must be thoroughly mixed, and the variation coefficient CV is less than 7%, which is the key to ensuring product quality, so the mixer must select a model, such as biaxial horizontal blade mixing. Machine, its mixed uniformity, high yield, fast mixing speed. The material enters the back process after the secondary comminution and secondary ingredients are mixed.

In the extrusion of the puffed process, the material actually passed a high temperature, high humidity and high pressure conditions. In this process, the physical and chemical properties of the material have changed strong, and the material is extruded from the mold hole. Since the pressure suddenly falls from high pressure to 100 kPa, the moisture in the feed is released from the liquid transformation into a gaseous from the feed. Thus, the material is inflated to form a so-called puffed feed. Since this feed is not only the advantages of general hard particulate feed, it is good, avoiding the automatic grading of the product, which is convenient for transportation, which helps digest, reduce feeding process, etc., and also have unique advantages: feed The starch is high, and the protein is more digestive, and the utilization of animals is improved; with excellent floatingness, it is easy to observe the fish’s feeding, and can maximize water pollution. These are also the main cause of extensive application of puffed feed. RQE China Feed Industry Information Network – Based on Feed, Service Animal Husbandry After the extrusion of the swivel machine, the wet soft particles (moisture are 25% to 30%), when It is best to use pneumatic conveying without adopting hoist enhancers. Because the hoist improvement is easy to cause the particles to break, improve the powdering rate; the way to use pneumatic conveying, not only the surface of the particles can be quickly formed, but the particles are broken, but also the shape of the granules can be rounded. . The material from the gas is high due to its high moisture content, so it must enter the dryer to dryness, so that the moisture of the material is reduced to about 13%. There are many kinds of dryers, and the author believes that when the diameter of the particles is less than 4 mm, a vibration fluidized bed dryer can be selected; when the diameter of the particles is greater than 4 mm, the tape dryer can be selected, or the horizontal float drying is selected. machine. Because this dryer can make the material in the entire screen surface, it can ensure the drying effect, and the damage to the particles can minimize. After drying, the material is dried and enters the outer spray system. External spraying of the particles is mainly to meet the needs of fishes and reduce the loss of thermal substances during processing. The nutrients that should not be added in the front process can be supplemented outside the spraying, and it can also improve the marginality of the feed and reduce the content of the powder. The best working temperature of this process is around 80 ¡ã C. After the material passes through the outer spray system, it can be cooled in a counterfluidic cooler.

The cooling material is subjected to the grading after the increase in the hoist. The fractionation screen is generally two-layer sieves, and the lower screen sieve is a finished product, and it can be directly entered into the finished product bin and packaged. Upper screenThe sieve must be returned to the crusher broken.The lower screen sieve is generally a fine pulverized material, which can be re-returned as a waste.The production process analyzed above is a conventional configuration of the current aquatic puffed feed process, using this process, which can produce overwhelming feed, slow dosing and floating feed.Although the puffed feed processing process has been recognized by many manufacturers as a new type of processing, it is much larger than the processing technology of its investment relative to hard particle feed, and it is not widely used.Despite this, the puffed processing process is the trend of future feed processing industry, especially in the application of aquatic animal feed and pet feed, will replace the traditional hard particulate feed process.
