4-5T/H floating fish feed plant

The quality of aquatic products will be the inevitable development of aquaculture in the new century, and the use of 4-5t/h floating fish feed mill plants to process extruded feed will be the main means of producing high-quality and safe animal products. At present, a new model of processing and breeding with extruded pellet feed as the mainstream has been formed in many countries and regions around the world.

With the promotion and application of extruded feed in the aquaculture market, more and more compound feed factories have begun to introduce floating fishfeed plant and extruding equipment, and many aqua feed companies are upgrading their floating fish feed manufacturing processes and production capacity through new construction, adding floating fish feed making plants, and technological transformation to meet the opportunities and challenges of market development.

4-5TPH Floating Fish Feed Plant process flow

The 4-5t/h high-end aquatic floating fish extruded feed plant solutions provided by Richi Machinery are based on modular design and are tailored according to customer needs. It can fully meet the customer’s demand for floating fish and other various extruded feed production, and meet strict hygiene standards to provide animals with green, clean and hygienic safe feed.

Process design of 4-5 t/h floating fish feed plant

The 4-5t/h floating fish feed manufacturing process mainly includes the receiving of feed raw materials, the removal of impurities and iron from the raw materials, grinding or micro-grinding, ultra-fine grinding, batching, mixing, transportation, weighing and packaging, etc. For extruded aquatic feed, it also includes puffing, drying, coating, cooling, screening bagging, etc.

The reception of feed raw materials and the removal of impurities and iron from the raw materials are the same as the production process requirements of general livestock and poultry feed, and no special requirements are required. But the requirements for crushing and mixing are higher. And because the aquatic feed contains more protein and oil, it increases the difficulty of crushing and mixing. For example, 80% of the raw materials of shrimp feed pass through 0.25mm sieve hole and 97% through 0.425mm sieve hole after crushing, and the raw materials of eel feed and soft-shell turtle feed should reach 80-120 mesh after crushing.

floating fish feed plant fish meal processing equipment

Crushing is one of the key processes in the 4-5t/h floating fish feed plant. High quality aqua feed should use micro-grinding equipment, and ultra-fine grinding process should be arranged in the production process of eel feed and soft-shelled turtle feed. For the one-time micro-pulverization that cannot all meet the pulverization requirements, it is necessary to match the micro-powder classification or ultra-fine powder classification equipment, so that the unqualified coarse particles after being pulverized by the classification equipment are re-pulverized. The classifier should be adjustable to suit different fineness requirements. The smaller the content of a certain ingredient in the feed, the higher the fineness requirement, so that the ingredients of the mixed feed are consistent.

Mixing is also one of the key processes in 4-5t/h fish feed plant. Whether the mixing is uniform or not directly affects the stability of feed quality. The purpose of blending is to mix the various nutrients evenly so that the subject gets all the nutrients they need in each ingestion.

floating fish feed plant raw materials for fish feed production

Compared with other mixers, the double-shaft horizontal mixer has the advantages of uniform mixing, less mixing residue, easy cleaning, more oil can be added, and shorter mixing time. Belt mixer. Since the raw materials of aquatic feed are finely crushed and contain more protein and oil, it is easy to cause arching during transportation, storage and processing.

In the extrusion process of 4-5t/h floating fish feed factory, a floating fish feed extruder machine should be used. Aquatic feeds with high requirements on water stability, such as shrimp feed, should be selected with appropriate binders added to the raw materials, which also helps to improve the stability of the feed in water. The pellets after extrusion contain high moisture content, and they must be cooled (some must be aged, dried, and cooled) to obtain qualified feed. During ripening, heating the feed to keep warm and moisturizing is beneficial to further gelatinization of starch.

During drying, heating and dehumidifying the feed is also conducive to starch gelatinization, reducing the moisture content and obtaining a more solid feed. Rapid cooling after drying reduces moisture content to safe storage requirements and lowers feed temperature. After sieving, the finished pellet feed can be obtained, which can be sold after weighing and packaging by automatic bagging machine.

RICHI series 4-5t/h floating fish feed plant adopts batching, secondary mixing, micro-grinding, curing, drying, cooling, crushing and screening, etc. The investment is not large, and the product quality is guaranteed. It not only focuses on the production of floating fish feed, but also can be customized design, taking into account the production of sinking fish feed, shrimp feed, livestock and poultry feed.

Due to the adoption of the latest maturing, countercurrent drying and countercurrent cooling technologies, the produced aquatic feed can ensure that it does not dissolve in water for a long time, does not collapse, reduces water pollution, and is suitable for aquatic animals to eat. This 4-5t/h floating fish feed system process is suitable for use in various countries, and is a relatively advanced and practical process for producing aquatic feed.

In line with the benign development needs of global fishery feed for low pollution, low waste, high efficiency and high conversion, aquaculture extruded feed made from 4-5t/h floating fish feed unit is gradually being accepted and recognized by the market, and has become a new trend in the development of the industry.

Selection of 4-5 t/h floating fish feed equipment

Crushing process and equipment

The crushing particle size of raw materials affects the digestibility and utilization rate of feed, and also directly affects the mixing uniformity, conditioning effect and water resistance of the finished product. In order to achieve the ideal pulverization effect, the secondary pulverization process is often used for 4-5t/h floating fish feed plant.

The first pulverization (that is, the coarse pulverization) reaches 20-36 mesh, and the second pulverization reaches the fine pulverization particle size (40-60 mesh) or the ultra-fine pulverization particle size (greater than 80 mesh).

fish feed plant cost aquaculture fish food suppliers

The first grinding section has two modes:

  • First crush and then ingredients: raw material crushing (primary crushing) – batching bin – first batching – first mixing – second crushing, this method is a single raw material crushing method commonly used for livestock and poultry feed production.
  • Ingredient first and then crushed: raw materials – ingredients – first mixing – first crushing – second crushing.

At present, the models used for the first pulverization of 4-5t/h floating fish feed plant include water drop hammer mill feed grinders, horizontal-width vibrating pulverizers, etc., which are characterized by large output and small particle size, and can satisfy high-fiber corncob and high-fat soybeans. Work under load without blocking the screen. The second pulverization: fine pulverization or ultrafine pulverization.

The crushing that exceeds the particle size requirement of 80 meshes is completed by an ultrafine pulverizer. At present, most of the ultrafine pulverization adopts a meshless ultrafine pulverizer. The crushing particle size requires 40-60 mesh, which can be done by a micro-grinder.

floating fish feed plant fish floating feed machine

There are two types of micro pulverizers, one is a horizontal pulverizer with a mesh, its main engine speed is about 1600r/min, and the screen apertures vary from 0.8mm, 1.0mm, 1.2mm; the other is a coarse pulverizer. On the basis of pulverization, go through a horizontal-width vibrating pulverizer once, and the screen aperture can also be between 0.8 and 1.2 mm.

Mixing process and equipment

The factors that affect the mixing uniformity during 4-5t/h floating fish feed plant processing include fish feed mixer machine type, mixing time, loading factor and material characteristics. The production of aquatic feed often uses a horizontal double-shaft paddle high-efficiency feed mixing machine or a double-shaft double-screw mixer. The former has a mixing time of 2 to 3 minutes and a CV of less than 5%; the latter has a mixing time of 5 to 6 minutes and a CV of 5% to 6%. .

floating fish feed plant fish feed making

4-5T/H floating fish feed plant often uses two mixing processes:

  • The first time: the raw materials are coarsely crushed – the first batching – the first mixing – the second crushing.
  • The second time: the secondary crushing of materials (micro crushing, ultra-fine crushing) – the second batching (including liquid addition, premix addition) – the second mixing – granulation bin.

Extrusion

In recent years, extruded aquafeed has been widely used in the breeding of sea and freshwater fish and frogs, and is considered to be a very promising aquafeed. There are single-screw fish feed extruder and twin-screw extruder used in 4-5t/h floating fish feed extrusion system. It is generally believed that the performance and economic benefits of twin-screw fish food extruders are superior to those of single-screw extruders. And in medium and large floating fish feed mill factoies, only twin screw extruders can better achieve large output.

Cooling and drying

In the 4-5t/h floating fish feed making process, the heat treatment time is long, the temperature is high, and the moisture content is large, so the cooling and drying capacity is required to be greater than that of livestock and poultry feed. The instant moisture of the extruded aquatic feed out of the die hole is about 25%, and the drying of the extruded feed is carried out in two steps, namely, hot air drying and cold air drying.

Hot air drying is usually carried out in a circulating drying oven, which is specially designed for the puffing process of 4-5t/h floating fish feed plant. It draws hot air from the heat exchanger through a high-power fan, and the hot air moves rapidly in the drying oven to take away the hot particles and volatilize. In order to achieve the purpose of drying, hot air drying can reduce the moisture content of pellets to 14% to 18%.

floating fish feed plant floating fish food pellet machine

Cold air drying is also a process of cooling and drying extruded pellets. It can reduce the moisture by 2% to 3%, so that the moisture content of the finished product is between 11% and 12%. It is usually completed by a pellet cooler machine. The wind flow and the feed flow move relative to each other, the wind flow is from bottom to top, the feed flow is from top to bottom, and the wind flow takes away moisture upward.In order to achieve the effect of cooling and drying, the design of the counterflow cooler should pay attention to the following aspects:

  • Shorten the length of the entire air duct system as much as possible, reduce the number of elbows, and prevent powder deposition;
  • Shorten the length of the horizontal air duct as much as possible to prevent the generation of condensed water;
  • Reasonably select the diameter of the air duct to ensure that the wind speed in the air duct is 13-16m/s, and the wind speed less than 13m/s will cause powder deposition and condensate water. (Related product: Fish Feed Dryer Machine)
