fish food factory

Process design of 16-20 t/h floating food factory for fish

As an important part of the feed industry, aquafeed has been paid more and more attention by manufacturers and aquaculture owners.

Due to the special feeding requirements of fish, shrimp and other aquatic products, the 16-20t/h fish food factory production technology and equipment are constantly updated and developed. Currently, floating fish feed pellet production are usually produced using two production processes:

1. First batching, then crushing, then mixing, granulating, post-curing, cooling, grading, grading after leaving the warehouse, packaging and leaving the fish food factory;
2. The ingredients are firstly crushed, then pulverized, mixed, puffed, dried, cooled, classified, and then classified out of the warehouse, and then packaged and shipped out.

Both of these two fish feed production processes can meet the fineness, the uniformity of mixed material particles, and the quality of granulated or extruded pellet required for the production of aquatic feed.

And can overcome the difficulty of single pulverization of high-protein materials and the over-fineness of raw materials after pulverization, and a series of problems in the production process of 16-20t/h fish food mill factory.

Ensure the smooth flow of the fish feed production process:

• ①The arrangement of the fish food making machine should be carried out in the order of the 16-20t/h fish food making factory process flow, and the height of the building should be used as much as possible to make the material flow freely, reduce the number of lifting times, and save the land occupation and construction area;
• ② The same fish food making machine should be arranged centrally for easy management;
• ③ The magnetic separation equipment in the cleaning section is placed after the primary cleaning screen, and the magnetic separation device is equipped in front of key equipment such as pulverizers, granulators and extruders;
• ④The arrangement of the batching bins is reasonable, which is conducive to the arrangement of the feeders. The layout of the batching bins can be rectangular or circular, and the batching bins should be equipped with exhaust facilities; The distance should be no more than 0.5m to reduce the air drop and ensure the batching accuracy;
• ⑤ For fish food making machine with large vibration and noise, such as crushers, it can be arranged on the first floor or basement, and a soundproof room should be installed on the first floor or other levels;
• ⑥ Equipment with large vibration should not be arranged around the batching scale, and the central control room should have sound insulation and air-conditioning facilities to ensure the batching accuracy;
• ⑦The fish feed mixer should be arranged below the batching scale, and the volume of the buffer bucket under the mixer should be configured according to the type of mixer, but at least one batch of materials can be stored; the conveying distance between the mixer and the finished product warehouse should not be too long;
• ⑧ The return pipe of the fish feed pellet machine and the floating fish feed extruder machine must be connected to the inlet head of the feeder to ensure the smooth flow of the 16-20t/h fish food productioon factory process. Air conditioners, dryers and grading screens should be directly arranged in the next channel, so that all kinds of materials can easily enter their respective processes;

Generally, the width of the walkway is 1~1.2m, the width of the main walkway is 1.2~1.5m, the horizontal walkway between the equipment is 0.6~0.8m, and the distance between the non-operation surface of the equipment and the wall is 0.35~0.5m. When arranging equipment such as cylinder cleaning screen, vibrating grading screen, hammer mill feed grinder, etc., special attention should be paid to leaving enough operating space for replacement parts;
• ②The maintenance hook should be set above the large equipment, and the load and height of the hook should be determined according to the maximum load and minimum lifting requirements of the equipment;
• ③ Hanging holes shall be provided on each floor of the multi-storey fish food factory building, and the upper and lower floors shall be aligned. The size of the hole and the load of the hook on the top of the hole are determined according to the largest part of the fish food equipment. A cover plate or a railing shall be laid on the hole;
• ④Flanges on equipment or pipelines shall not be arranged in the holes passing through the floor or wall, so as not to affect the maintenance, and the reserved holes should leave enough space for operation;
• ⑤The easy-to-wear chute, tee, distribution plate and hopper need to be equipped with wear-resistant plates, and at the same time consider the inspection door and set up the inspection platform;
• ⑥Cylinder warehouse and batching warehouse, transition bucket and finished product warehouse of large feed factory, a ladder should be set up in the warehouse;
• ⑦Every motor should be set with a base or an anchor rail, which is convenient for maintenance.

Easy to operate and ensure safety

• ① The operating points of the fish food factory equipment, such as the handwheel of the gate, the wrench of the flap, various buttons and the refueling point, etc., should be placed within the range of human hands and easy to operate. If there is difficulty, adjust the installation height, add an operating platform or step. For the gate that is too high, the hand wheel can be replaced by the hand zipper chain wheel;
• ② Pay attention to the convenience of the passage of the workshop, and the passage of the stairs should not be too steep or narrow; the stairs should be placed indoors as much as possible; the climbing ladder should be used as little as possible;
• ③ Safety railings should be set up on the edges of stairs, walkways, roofs, warehouse roofs and operating platforms;
• ④ All rotating equipment components, such as couplings, pulleys and transmission belts, sprockets and chain drives, must be equipped with protective covers;
• ⑤ Any pipes, air ducts, transition buckets, etc. with a certain weight should be provided with brackets or hangers for support and fixation, and their weight cannot be directly pressed on the relevant equipment;
• ⑥ The distance between the side of the foundation bolt hole and the foundation should generally not be less than 0.1~0.15m. When the diameter of the bolt is small and the length is short, take the lower limit, otherwise, take the upper limit to ensure the installation quality of the anchor bolts and facilitate civil construction.

Note:

1. The 20t/h fish food factory project will generate dust during the feeding, crushing, mixing, screening and packaging processes. Therefore, the process considers installing fans and pulse dust collectors at various dust generating points to recover useful materials and reduce dust pollution in the workshop. .
2. The steam required for puffing, tempering, drying and other processes in this 20t/h fish food production project comes from centralized gas supply, and there is no boiler gas supply in this project.

The gate of the 20t/h fish food line project is located near the village road on the west side. The 20t/h fish food plant area is mainly divided into living area and production area.

The main production workshop of the original project livestock and poultry feed production line is located in the center of the plant area, the finished product warehouse is located in the west side of the center of the plant area, and the raw material warehouse of the 20t/h fish food mill factory area is located in the east.

The packaging room is located in the southwest corner, the 20t/ht expansion fish food project is located in the east of the raw material warehouse, and the office space in the living area is located in the northwest corner.

From a policy perspective, the world now pays great attention to ecological and environmental issues, especially carbon emissions in economic development.

Livestock and poultry farming also cause a lot of carbon emissions, and aquaculture has an incomparable advantage in this regard. Producing aquatic products that provide the same quality of protein emits far less carbon than raising livestock and poultry.

The two strategies to face the new changing situation are the great development of the industrial chain and the great upgrade of feed enterprises. Select high-end varieties in the industry, develop the industrial chain for intensive processing; and then improve international competitiveness through brand building.

Feed products need to be responsible for nutrition and environmental protection. Pellet feeds are upgraded to extruded feeds, and low-grade feeds are converted to high-grade feeds; functional health-care materials are used to ensure food safety, and attention is paid to animal protection and water adjustment.

The RICHI MACHINERY engineer team’s “return to product technology and think about everything” is not a simple slogan, but a systematic development concept.

Deeply understand fish food processing technology and breeding benefits (operation), explore the real pain points and benefit improvement points of mainstream feed processing models, formulate cost-effective products and fish food system technical solutions, and effectively serve customers through solutions, so that users can obtain higher than the market average.

At the same time, it realizes the conversion and promotion of product sales, continues to shape the brand image of RICHI “fish food production unit supplier”, and builds the competitive advantage of RICHI fish feed equipment beyond price.
