DSP Fish Feed Extruder Machine Introduction 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 adapted 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. Sizes of final feed pellets range from 0.9 to 15mm. Wet-type fish feed pellet machine is mainly used in medium or large-size feed pellet plants and aquaculture farms. Using this wet type fish feed pelletizer 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. 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 core of extruder machine work is: pretreatment, cooking, and die shaping. The boiler continuously provides hot steam to the conditioner, so that the mixture is fully cooked and the nutritional value is improved. The cooking process results in a high degree of gelatinization of the starch, resulting in good water stability of the feed. The fish feed extruder is a long barrel with an auger inside, specially designed to subject the feed mixture to high temperature and steam pressure. When the feed comes out of the mold at the end of the barrel, the trapped steam is quickly expelled, and the soft and warm pellets expand to produce low-density floating pellets. Afterward, cutting equipment cuts the shaped pellets into the required different lengths. The extruder is very versatile and can produce feed with many different characteristics. Note: Our fish feed extruder is single screw design. The temperature of the pellets extruded by the granulator is about 80°C, and the moisture content is 18%-20%. If the output is more than 500kg/h, it needs to be equipped with a dryer and a cooler. For small volumes, you can place them in the sun to dry. After placing the order, we also provide the technical formula for making floating fish feed pellets.

Grass Feed Pellet Machine Introduction It is a professional industrial use of grass pellet machinery that produces grass pellets. The key to grass pelletizing is the water content of the raw grass. First of all, we must measure the moisture content of the raw materials. Then, regulate it to an appropriate value by adding water or sun-drying. Research shows that the best moisture content for leguminous forage grass pellets is 14% to 16%. For Gramineae forage grass pellets it is 13% to 15%. In fact, grass pellets can also be used as fuel for heating if the moisture is accurately controlled. Grass pellets may produce more ash than wood pellets, and the calorie in grass pellets is not so much as in wood pellets, but grass pellets have still a well-accepted method in Europe for a long time. In a word, the grass pellets are an excellent choice for both feed and fuel.

HM Belt Type Feed Pellet Mill Introduction The belt-type ring dies feed pellet machine is a large-scale feed pellet machine, which is used to make corn stalks, bean stalks, flower seedlings, sweet potato wine, clover, rape straw, etc. into cattle feed, pig feed, cattle feed, sheep feed, rabbits feed, chickens feed, ducks feed, etc. The ring dies feed machine is the preferred equipment for making feed in large and medium-sized feed factories and various livestock farms. It is suitable for granulation in feed mills, farms, and chemical industries. This ring dies feed grinder can make various materials into pellets for livestock feed, grass powder, and organic fertilizer materials. Feed Pellet Mill Structure Our feed pellet machine is mainly composed of a feeder, modulator, pellet mill, lubrication system, and so on. The operation process requires that the mixing degree of the material should not exceed 15%. The material enters the feeding screw through the silo. Change the speed by adjusting the step-less speed regulation motor to make the material flow moderately. Then start tempering by mixing with steam through a paddle mixer. After tempering, the material temperature can be between 64°C and 84°C, and the humidity can be between 14% and 16%. Finally, the material enters the press box through the chute for granulation. HM Belt Type Feed Pellet Mill Features 1. The feeder of our belt-type feed pellet machine adopts the originally imported frequency conversion controller, and the feeding is uniform and accurate. 2. The conditioner is all made of stainless steel to ensure that it will not deteriorate in the steam environment for a long time. It is also designed with inspection doors for easy cleaning and maintenance. During the tempering process, the feed is in full contact with the steam, and the degree of maturation of the feed is higher, which is conducive to the production of high-quality pellet feed. 3. The feed inlet is designed with a deflector, which can control the flow direction of the material (into the cutting chamber or directly discharged from the bottom). It is convenient to prevent materials with the wrong ratio from entering the granulation system. 4. The transmission belt adopts a high-strength SPB V-belt, the transmission is stable and reliable, and the noise is low. 5. The ring die is also made of 100% stainless steel for extra durability. There are a variety of apertures for you to choose from (φ1.5mm~φ12mm), and the compression ratio is customized according to your specific raw materials. 6. The quick-release hoop mold design makes replacement more convenient and greatly improves production efficiency. 7. One-piece spindle, easy to disassemble and assemble, good mechanical performance. 8. Scraper: 1 outer scraper, 2 inner scrapers. (Outer scraper is used to cut feed pellets with adjustable pellet length; inner scraper is used for mixing and deflection) 9. Reasonable lubricating system design (spindle, pressure roller): specially designed refueling holes to achieve non-stop refueling.
