New Build 20-21T/H Customized Automatic Floating Fish Feed Mill Plant For Extruded Fish Pellets

Agriculture is the most basic industry of consumer goods in China. The food or protein we take in every day is basically related to agriculture. At the same time, consumers influence the direction and mode of agricultural production. As we all know, aquatic products are rich in protein and protein is the main nutrition of the human body.

In addition, with the upgrading of consumption, people's protein satisfaction has become healthy and safe. Therefore, the change of people's lifestyle has promoted the increasing demand for aquatic products.

Based on the potential development of the aquatic feed industry, the client invested 20 million yuan (3140000USD) to build a 20-21t/h customized automatic floating fish feed mill plant project with an annual output of 50,000 tons of extruded feed in Kaifeng City, Henan Province, China.

Process of making floating fish feed

The followings are details of floating fish feed production process in this fish feed mill project.

1. Feeding section

   The raw material enters the elevator through the screw conveyor, and is lifted to the upper part of the elevator to enter the magnetic separation equipment.

2. Magnetic separation

   Mainly remove iron-containing impurities in raw materials, avoid entering subsequent sections, and select permanent magnets for high-strength magnetism.

3. Ingredient crushing section

   The material after magnetic separation is temporarily stored in the silo to be pulverized, and is slowly fed into the raw material by the screw conveyor through speed regulation.

   The fish feed pulverizer coarsely pulverizes the raw materials and increases the surface area of ​​the materials, which is convenient for conditioning and puffing in the subsequent sections.

   Choose the SFSP series enhanced water drop mill for grinding fish feed materials. Pulverization increases the dust removal process and improves the pulverization efficiency.

4. Puffing section

   The material is crushed by the fish feed grinder and then distributed to 4 silos to be extruded through the lower closed air screw conveyor, bucket elevator, upper part auger, and pneumatic gate.

   The auger enters the extruder machine for fish feed at a constant speed to heat up, pressurize, knead, and then quickly eject from the die hole to complete the extruding process. Use the new EXP160 dry corn special extruder.

5. Cooling section

   The temperature of the material after puffing is 110-140℃, and the temperature needs to be lowered in the cooling section to meet the requirements of the subsequent crushing and packaging section. The patented technology of the cooling silo is used to quickly reduce the temperature of the extruder feed.

6. Finished pellets crumbling section

   The puffed feed is cylindrical and large in shape. The feed is crumbled by a crumbler, and then pulverized into a powdery feed, which is subjected to negative pressure sedimentation through a high-pressure fan and a cyclone dust collector.

7. Finished product screening section

   After the negative pressure settling, the powdery materials enter the elevator for material screening, the floating fish pellets that meet the requirements enter the finished product warehouse, and the materials that do not meet the requirements enter the fish feed hammer mill for re-pulverization. After pulverization, they are lifted again and entered into the screening.

8. Finished product packaging section

   After screening, the finished materials flow into the finished product warehouse and enter the automatic packing scale. The automatic packing scale will automatically weigh and seal the packing bags, and then carry out pallet stacking. The forklift truck will put it into the finished product storage area to complete all the process engineering.

Project water supply and drainage

Water supply

The fresh water consumption of this 20-21t/h extruder feed mill project is 0.83m3/d, 249m3/a, mainly for cooling water circulation and domestic water for employees.

The water used in this 20-21t/h extruder fish feed mill project is self-provided wells in the 20-21t/h extruder feed mill plant, which can meet its water demand.

• Cooling circulating water

  According to the information provided by the company, the cooling cycle water volume of this 20-21t/h extruder feed mill project is 12m3/a, which is recycled and discharged every six months. Therefore, the cooling cycle supplementary water consumption of this 20-21t/h extruder feed mill project is 0.080m3/d, 24m3/a,

• Water for domestic use

  The 20-21t/h extruder feed mill project plans to employ 15 employees, all of whom are not in the fish feed mill factory for board and lodging (the water consumption index for board and lodging outside the factory is calculated as 0.05m3/d·person), and the annual work is 300 days, the office and domestic water consumption is 0.75m3/d, 225m3 /a.

Drainage

The cooling water of this 20-21t/h extruder feed mill project is used for recycling, but it needs to be discharged regularly. Therefore, the wastewater of this 20-21t/h extruder floating fish feed mill project is mainly office and domestic wastewater.

Worker's office and domestic wastewater: The discharge amount of the staff's office and domestic wastewater in this large floating fish feed mill project is calculated as 80% of the staff's office and domestic water consumption, then the employee's office and domestic wastewater discharge is 0.60m3/d, 180m3/a, which is treated by the septic tank in the 20-21t/h extruder feed mill afterwards, the compost is regularly pulled away by nearby villagers.
