Process flow of 6 t/h fish feed mill plant
The feeding of this fish feed processing line project (flour, fish meal, soybean meal, peanut meal) adopts manual feeding, and the materials are sent to the primary cleaning sieve of the pellets and the primary cleaning sieve of the powder through the elevator for impurity treatment.
After the screening is completed, the material enters the batching bin through the pipeline by gravity, and then enters the double-shaft high-efficiency mixer through gravity for material mixing. machine for material mixing.
After the mixing is complete, the material is sent to the permanent magnet cylinder through the elevator for iron filings processing, and the processed material is sent to the silo to be crushed by gravity, and the material is sent to the pulverizer for coarse crushing by gravity.
After the coarse powder is completed, the material is sent to the permanent magnetic cylinder through the elevator for iron filings treatment, and the processed material is sent to the ultrafine pulverizer for ultrafine pulverization.
After the crushing is complete, it is sent to the batching bin through the elevator, and the material is sent to the double-shaft high-efficiency mixer by gravity, and at the same time, the material is added to the double-shaft fish feed mixer through manual feeding (vitamins, trace elements, drugs, etc.) for material mixing. After mixing is complete, the material is sent to the permanent magnet cylinder through the elevator for iron filings treatment.
①After the treatment is completed, the materials used to produce extruded feed are sent to the wet extruder for expansion, and the expanded materials are sent to the box dryer for drying.
After drying, they are sent to the rotary grading screen for grading treatment, and the qualified materials are sent to the buffer bin, unqualified materials are sent to the production device in the 6t/h fish feed mill plant for reproduction, qualified materials are sent to the buffer bin by gravity, and soybean oil is added to the buffer bin through a grease sprayer.
And then the materials are sent to the rotary classifier by gravity for grading treatment, and the qualified materials are sent to puffing the unqualified materials are sent to the production device in the factory area for reproduction, and the final qualified products are packaged and put into storage.
② After the treatment is completed, the materials used to produce sinking fish compound feed are sent to the flat-bottom broken arch feeding bin, and are sent to the fish feed pelletizer for granulation by gravity. After the granulation is completed, the materials are sent to the stabilizer by gravity for secondary aging.
After the curing is completed, it is sent to the flap cooler for cooling. After the cooling is completed, the material is classified by the rotary sieve. After the compound feed (large particles) is sent to the silo, it is sent to the particle cleaner for treatment by gravity. After processing, it is packed into storage.
Sinking fish pellet feed (small pellets) sends the material to the permanent magnet cylinder for iron filings treatment by gravity, and the processed feed is sent to the silo, and is sent to the crusher for processing by gravity, and the processed feed is packaged.
