Description

Technical Field

[0001] This utility model relates to the field of feed machinery technology, and in particular to an aquatic feed pelleting system. Background Technology

[0002] A typical aquatic pelleting system includes a pelleting hopper, a feeding auger, a conditioner, and a pellet mill. The conditioner is equipped with a steam system. During operation, the feed ingredients enter the feeding auger from the pelleting hopper, then from the auger into the conditioner. Simultaneously, steam is introduced from the conditioner's steam system to condition the feed ingredients. The conditioned ingredients then enter the pellet mill for pelleting.

[0003] As the aquaculture industry places increasingly higher demands on the quality of aquatic feed, such as requirements for feed maturation, stability in water, pellet hardness and pulverization rate, as well as the need for a wider range of raw material choices to reduce raw material costs, these requirements pose challenges to the current conditioning and pelleting technology. Existing pelleting processes can no longer meet the needs of the industry's development. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides an aquatic feed pelleting system.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an aquatic feed pelleting system, including a feeder, a conditioner, and a pellet mill arranged in a process flow. The inlet end of the feeder is connected to a pelleting bin, and the outlet end of the feeder is connected to the inlet end of the conditioner. The conditioner is provided with a steam pipe for introducing steam into the conditioner. A preservation device and an expander are arranged in sequence between the conditioner and the pellet mill. The feed raw materials that have been conditioned in the conditioner enter the preservation device, and the feed raw materials that have been preserved in the preservation device enter the expander. The feed raw materials that have been treated in the expander enter the pellet mill for pelleting.

[0006] Furthermore, in order to achieve the effect of uniform material feeding, a first uniform feeder is provided between the quality retainer and the expander. The discharge end of the quality retainer is connected to the feed end of the first uniform feeder, and the discharge end of the first uniform feeder is connected to the feed end of the expander.

[0007] To prevent large pellets from entering the pellet mill, a crusher and a second uniform feeder are sequentially installed between the expander and the pellet mill. The feed raw materials processed by the expander enter the crusher for crushing and then flow to the second uniform feeder. The discharge end of the second uniform feeder is connected to the feed end of the pellet mill to improve the uniformity of the raw material particles flowing into the pellet mill.

[0008] Furthermore, the aforementioned shelf-life device is driven by a variable frequency speed reducer to facilitate adjustment of different shelf-life times.

[0009] To facilitate adjustment of the gelatinization degree of feed ingredients, the discharge end of the expander is equipped with a hydraulically controlled intermittent discharge device.

[0010] The beneficial effects of this utility model are as follows: By adding a conditioner and an expander to the pelleting system, the conditioner can greatly improve the conditioning and maturation time of feed raw materials, thereby improving the nutritional value and pelleting performance of the feed; while the expander can further squeeze, knead, shear, and heat and pressurize the feed raw materials, thereby improving the nutritional value of the feed, increasing the feed conversion rate and the output and pellet quality of the pellet mill, reducing the powdering rate of pelleted feed, and improving the water stability of pelleted feed.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0015] like Figure 1 The aquatic feed pelleting system shown includes a feeder 2, a conditioner 3, a conditioner 4, an expander 6, and a pellet mill 9 arranged in the process flow. A pelleting bin 1 for storing feed raw materials is connected to the inlet end of the feeder 2, and the outlet end of the feeder 2 is connected to the inlet end of the conditioner 3. A steam pipe 10 for introducing steam into the conditioner 3 is provided on the conditioner 3.

[0016] The quality retainer 4 and the expander 6 are located between the conditioner 3 and the pellet mill 9. A first uniform feeder 5 is also provided between the quality retainer 4 and the expander 6. The feed raw materials that have been conditioned in the conditioner 3 enter the feed end of the quality retainer 4 through the discharge end. After being conditioned by the quality retainer 4, the feed raw materials are mixed evenly by the first uniform feeder 5 and then enter the feed end of the expander 6.

[0017] Between the expander 6 and the pellet mill 9, there is a crusher 7 and a second uniform feeder 8 arranged in sequence. The feed raw materials processed by the expander 6 first enter the crusher 7 for crushing, and then the crushed raw materials flow into the second uniform feeder 8 for mixing evenly before entering the pellet mill 9 for pelleting.

[0018] The aforementioned quality control device 4 is driven by a variable frequency speed reducer 11, which can adjust the degree of maturation of feed raw materials by using different shelf times according to feed formula, product quality and output requirements, thereby increasing process flexibility; the discharge end of the expander 6 is equipped with a hydraulically controlled and adjustable gap discharge device 12, which can adjust the degree of gelatinization of feed raw materials by using different discharge gaps according to formula, product quality and output requirements, thereby increasing process flexibility.

[0019] Compared to traditional feed pelleting systems, this invention adds a conditioner 4 and an expander 6. The conditioner 4 can significantly increase the conditioning and maturation time of feed raw materials, improving the nutritional value and pelleting performance of the feed. The expander 6 can further compress, knead, shear, and heat and pressurize the feed raw materials, improving the nutritional value of the feed, increasing the feed conversion rate and the output and pellet quality of the pellet mill 9, reducing the powdering rate of pelleted feed, and improving the stability of pelleted feed in water. In addition, the system is also equipped with a first uniform feeder 5 and a second uniform feeder 8, which can stir and mix the feed raw materials, achieving uniform feeding, making the main unit run smoothly, reducing current fluctuations, and increasing production capacity. The crusher 7 can crush the raw materials to prevent large particles from entering the pellet mill 9, causing current fluctuations in the pellet mill 9 and reducing feed quality.

[0020] This system can perform deep conditioning and maturation of feed, increasing the output of pellet mill 9 by 20-60%, improving the gelatinization degree of the obtained aquatic feed pellets by 40-80%, increasing pellet hardness by 30-100%, reducing pulverization rate by 50-200%, and improving water stability by 30-90%.

[0021] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
