How is your fish feed machine ?

Fish Feed - Floating & Sinking Pellet

The single screw extruder offers a unique combination of quality output and low capital investment making it a cost effective solution for processing premium shaped products.

Flexibility to produce a wide variety of shapes and sizes are key features of this technology, with ability to make pellets as small as 1.5mm.

The resulting products are lower in post-extruded moisture, requiring less drying. Which provide benefits of less nutrient degradation and reduced operational and capital costs.

Advantage to adopt a fish feed mill machine ?

1. Fish feed pellets are the popular feed in modern commercial fish farming, providing balanced nutrition needed by fish stock and improving fish farm environment. Due to high price of feed pellets on the market, many farmers tend to purchase fish feed extruder to produce pellets by themselves to low the cost.

2. Storage: can be kept for two to three months when stored in a covered cool dry place.

3. Hygiene: expansion process can eliminate most bacteria. Low moisture content (about 10%) can prevent bacterial growth.

4. Nutrition: can be added with animal or plant protein, fish oil or other fats, vitamin complex and minerals required by specific fish species. It is highly nutritious and can effectively improve the health of fish stock.

5. Environmental impacts: using pellet feed of appropriate size and density can lower the loss rate and significantly mitigate the environmental pollution caused by the feed residues.

6. Pellet feed of different sizes and densities can be made to accommodate the needs of species in various growth stages and with different babits. By using pellet feed of the appropriate size and density, loss rate and environmental pollution caused by the feed residue can be significantly reduced.
 

Wet type floating fish feed pellet machine

      Wet type fish feed machine is widely used for producing grains into high-grade aquatic feed pellets for many kinds of pet like fish, catfish, shrimps, crab, cat, dog and etc. Grain materials employed in fish feed pelletizer are such as wheat, soybean, cake and other leftovers and etc., moreover puffing pellets produced by the pellet machine can float on the water surface without dissolution for over 12 hours. Wet type feed extruder is mainly employed in medium or large size feed processing factory and aquaculture farm. For large scale production of quality pellets, it is profitable to opt wet type feed pellet machine

Features of Wet Type floating fish feed pellet machine

1. Boiler continuously offer hot steam into the conditioner, so materials can be fully cooked and the nutritional value is improved. Thus the quality and quantity of pellets can be improved greatly with lower power consumption.

2. High temperature and high pressure process can kill the salmonellosis and bacterial infections and also makes the pellets easily to digest.

3. Key parts are processed through vacuum quench treatment with high processing precision, thus have a long service life.

4. Screw sleeve adopts jacketed construction, which can be injected in with hot steam or cooling water, thus the extruding temperature can be controlled effectively.

5. Single-screw extrusion cooking: large production capacities; variable screw speeds.

6. Key parts are processed through vacuum quench treatment with high processing precision, thus have a long service life.

7. You can change different molds to make pellets with different diameters.

Spare Parts of Single Screw Fish Feed Extruder

       Spare parts directly determine the machine quality. All our parts are manufactured from the best quality materials to make sure the service life of the components are as long as possible.

1. Screw sleeve adopts jacketed construction, which can be injected in with hot steam or cooling water, thus the extruding temperature can be controlled effectively.

2. Removable cutting mechanism use knives with good elasticity, which attach to the die plate tenderly and can be operated quickly and accurately.

3. Screw bolts and dies are processed through vacuum quench treatment, also be processed with high processing precision and have a long using longevity.

4. Due to high pressures, shear and abrasion inside the barrel of extruders, the easily-worn parts like barrel, screw periodically should be replaced. Our extruders are of the modular design so worn components can be easily removed and replaced as needed. Moreover, one fish feed pellet machine is equipped with extra easy wear parts for free including two sleeves, one screw, one cutting knife and  five  die moulds.

Working Principle of wet type floating fish feed pellet machine

      The heart of the extruder machine is preconditioning, cooking and die shaping. With boiler continuously providing hot steam into the conditioner, mixed materials from fish feed mixer can be fully cooked and the nutritional value is improved. The cooking process can cause a high level of gelatinization of starches, results in feeds with good water stability. The fish feed extruder is a long barrel with a screw auger inside which is specially designed to subject feed mixtures to high heat and steam pressure. When feed exits the die at the end of the barrel, trapped steam blows off rapidly, the soft warm pellets expand, and a low density floating pellet is produced. After that a cutting device will cut the formed pellets into different length as required. The extruder is very versatile, and can make feeds with many different characteristics.

Notes: our fish feed extruder is single screw designed. The pellets extruded from pellet mill is about 80°C and moisture content is around 18%-20%, so you would better adopt a dryer and cooler if the capacity is more than 500kg/h. While for small capacity, you can dry them in the sun. We also provide technical formula for making floating fish feed pellets after order confirmation.
