  • Feed Pellet Forming Rate: >98%
  • Application: Fish, crab, shrimps farms, feed production workshop, etc.

DSP wet type floating fish feed 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 a pet, such as a dog, cat, and so on. Raw materials for this machine can be corn, soybean meal, rice barn, fish meal, rice barn, etc.

DSP Fish Feed Extruder Machine Introduction

The DSP wet-type floating fish feed machine is primarily designed to manufacture both floating and sinking aqua feed for fish, shrimp, eel, bullfrog, and more. Additionally, it can be adapted to produce feed pellets for pets such as dogs and cats. The machine utilizes raw materials like corn, soybean meal, rice bran, fish meal, and others. The produced feed pellets come in sizes ranging from 0.9 to 15mm. This wet-type fish feed pellet machine is best suited for medium or large-sized feed pellet plants and aquaculture farms. Its production results in expanded feed particles with a neat and smooth formation, ensuring they float for over 12 hours without sinking, preventing water pollution, and reducing the risk of fish diseases through sterilization.

DSP Fish Feed Extruder Machine Product Advantages

1. The operating parts adopt the humanized design, which makes the machine easy to operate.

2. The size of the feed pellets can be adjusted according to the requirements of customers by changing different molds.

3. During the high-temperature and high-pressure granulation process, salmonella and bacterial infection can be killed, and the granules can be easily digested and absorbed.

4. The floating pellets made by this wet fish feed extruder are of high quality and can float on the water surface for more than 12 hours.

5. The boiler continuously provides hot steam to the conditioner to fully mature the raw materials and improve the nutritional value of pellet feed.

6. The key components are vacuum quenched, with high processing precision and long service life.

7. Widely used in fish feed pellet plants, crab feed pellet plant production lines, shrimp feed pellet plants, etc.

DSP Fish Feed Extruder Machine Working Principle

The operation of the extruder machine revolves around three key processes: pretreatment, cooking, and die shaping. The continuous supply of hot steam from the boiler to the conditioner ensures thorough cooking, enhancing the nutritional value of the mixture. This cooking process leads to a significant gelatinization of starch, contributing to the feed's excellent water stability. The fish feed extruder, featuring a prolonged barrel with an internal auger, is intricately designed to subject the feed mixture to high temperatures and steam pressure. As the feed exits the barrel's end, the trapped steam is rapidly expelled, causing the soft and warm pellets to expand, resulting in low-density floating pellets. Subsequently, cutting equipment shapes the pellets to the desired lengths. The extruder's versatility allows for the production of feed with various characteristics.

Please be aware that our fish feed extruder features a single-screw design. The temperature of the extruded pellets typically reaches around 80°C, with a moisture content ranging between 18% to 20%. Should the output exceed 500kg/h, it is recommended to include a dryer and a cooler in the setup. For smaller volumes, sun-drying is a suitable option. Upon placing an order, we also offer the technical formula for producing floating fish feed pellets.
