Product introduction

DSP wet type extruder machine is mainly used to produce all kinds of floating or sinking aqua feed for fish, shrimp, eel, bullfrog, etc. It can also be adopted to produce feed pellets for pet, such as dog, cat and so on. Raw materials for this machine can be corn, soybean meal, rice barn, fish meal, rice barn, etc. Sizes of final feed pellets ranges from 0.9 to 15mm. Wet type fish feed extruder is mainly used in medium or large size feed pellet plants and aquaculture farms. Use this wet type fish feed extruder machine production expanded feed particles, forming neat and smooth, floating over 12 hours don't sink water,polluting the water, sterilization to reduce fish disease.

Product advantages

1. Operating parts adopt the humanization design which makes the machine easy to operate.

2. Sizes of the feed pellets can be adjusted according to the customer requirement by changing different molds.

3. Salmonellosis and bacterial infections can be killed during the high temperature and high pressure pelletizing process, which can also make pellets easy to digest and absorb.

4. Floating pellets made by this wet type fish feed extruder have high quality which can float on the water for more than 12 hours.

5. Raw materials can be fully cooked as the boiler provide hot steam into the conditioner continuously, so the nutritional value of the feed pellets can be improved.

6. Key parts have long service life as they are processed through vacuum quench treatment with high processing precision.

Raw Materials

The material selection is very wide, such as soybean meal, corn flour, wheat meal, bone meal, meat meal, fish meal and so on. Here is the material requirement:

Working Principle

The heart of the extruder machine working 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.

Attentions: our fish feed extruder is of single screw design. The pellets extruded from pellet mill is about 80℃ and moisture content is 18%-20%, so you should equip 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 placing order.

The Benefits of Puffed Fish Feed Pellets

1. From the fish feed extruder, feed pellets are in 'popcorn' state, not only physical state has been changed, but also shape and internal structure of organic molecules has been changed, which make feed pellets easier to digest and absorb for fish.

2. After treatment of puffing, fragrance and palatability of the feed has been improved to stimulate appetite of animal.

3. High temperature and high pressure process can kill the salmonellosis and bacterial infections and makes the pellets Hygeian for fish.

4. The puffed fish feed pellets can float on the water surface without dissolution for over 12 hours, reduce feed waste and keep the water quality.
