6. The structure of the floating fish feed extruder
Our new generation fish food pellet machine is mainly composed of three parts: feeding system, pelletizing system, and discharging system.
1. Feeding system: After the material is crushed, it first enters the storage bin above. The storage bin is designed with a large opening to facilitate feeding, and there is a spiral agitator inside, which evenly transports the material to the feed port of the granulation system below. The feeding system can ensure that the material can enter the pelleting system evenly, and ensure the quality of the finished feed.
2. Pelletizing system: The material enters into the lower granulation system after being evenly stirred by the feeding system. The material is under the condition of high temperature and high pressure in the advancing screw, and gradually forms a granular feed, which is finally extruded from the top die by the screw. The user can add an electric heating sheet outside the screw to assist with heating,
3. Discharging system: After the material is extruded through the die, it is cut by the final rotary cutter, then obtain the finished feed. The user can adjust the rotation speed of the blade and the distance from the blade to the die outlet to obtain different feed lengths, and adjust the aperture and shape of the discharge die to obtain different feed sizes.
4. Power system: Our fish pellet machine can use two different power modes, motor and diesel engine, and can also be modified into a hybrid power mode according to customer needs.
The main motor is mainly used to control the screw in the pelletizing system. The high-speed rotating motor makes the extrusion screw move forward smoothly and continuously through the deceleration motor, then it will form a high temperature and high-pressure condition.
In addition, the whole machine is equipped with two small motors, which are the feeding motor that controls the spiral stirring feeder in the feeding system and the cutter motor that controls the rotation of the blade when discharging.
7. The working principle of the dry way floating fish feed making machine
The crushed material enters the screw extrusion cavity after uniform stirring. Under the action of the main motor, a high temperature and high-pressure condition are formed in the cavity (an electric heating sheet can be added outside the cavity for auxiliary heating). At the same time, the material is in the cavity also accompanied by violent extrusion, stirring and friction in the process of moving forward. Under various actions, the temperature of the material in the cavity rises sharply, the starch in the material is gelatinized, and the whole material becomes a melted plastic colloid.
When the material is extruded from the mold, the moisture in the material quickly turns into steam, the volume of the formed feed expands rapidly, and the further evaporation of the water vapor reduces the moisture content of the feed. At the same time, the temperature of the feed drops rapidly, and it is finally cut by the rotary cutter and cooled.
8. The raw materials for floating fish feed pellet
Fish feed floats on the water face due to various reasons like low bulk viscosity, air sacs in extruded feed, low humidity, buoyancy – water stability & other extrusion properties nominated as floating fish feed.
The raw materials of floating fish feed are wide and colorful, substantially including fish mess, wheat meal, yeast powder, mineral and vitamin premix, soybean mess, cottonseed mess, peanut mess and rapeseed mess, etc. still, without proper and scientific expression, floating fish feed may show some blights like deficient nutrition, high feed measure, and low feed Application rate. Thus, it’s essential to choose a formula with good stability, low feed measure, and high feed application rate, and to master the production process overall.
9. The advantages of the floating fish feed machine
- The granulation equipment has a simple structure, small footprint, low noise, and long service life.
- The machine adopts a variety of powerful methods to meet the needs of different customers,
- The produced feed pellets have a smooth surface and internal ripening, which not only has good palatability but also improves the digestion and absorption of internal nutrients by fish.
- The high temperature and high-pressure environment during the formation of feed pellets can effectively kill bacteria, parasite eggs, pathogenic microorganisms, etc. in the material, and avoid various digestive system diseases.
- A variety of mold sizes and shapes are available to suit different species and sizes of fish.
10. Which is better floating or sinking fish food?
Floating Feed: This type of feed floats on water. These feeds go through the extrusion process during processing, so the purchase and manufacturing costs are advanced.
Sinking Feed: This is just contrary to the former. It’ll sink directly into the water. They’re more economical.
There are both pros and cons to the two types of pellets. Still, the use of floating pellets provides further advantages compared to sinking ones.
11. Features of extruded floating fish feed making machine
- The extruded aquatic feed can be suspended on the water surface for a long time, it helps farmers to carry out scientific feeding management.
- The utilization rate of extruded floating extruded material is higher.
- The impact of extruded fish feed on water quality is low.
- The floating fish feed pellet has a longer shelf life and is convenient for storage and transportation.
- The extruded feed pellet is very stable in water, it can avoid spoilage of feed pellet.
- The extruded feed can effectively kill harmful bacteria which can prevent the unclean feed from causing various digestive tract diseases.
12. Tips on How to use floating fish feed extruder
- When the fingerlings are stocked, when the water temperature is low, the growth is slow, and the size is small, the particle diameter of the feed should be controlled at about 2mm; when the temperature rises and the growth of fingerlings are accelerated, the medium-term feed particle diameter should be 3-3.5mm, and later in 4-4.5mm. Therefore, when using the fish feed pellet machine to process fish pellet feed, the size of the feed pellet should be adjusted according to the type of fish and different growth stages to achieve the best feeding effect.
- Because the fish has no stomach, the feed stays in the intestinal tract for a short time, and the digestion and utilization rate is not high; so when feeding the feed, it should be fed several times, and each feeding should be a little less; Improve feed utilization.
- During the use of the feed pellet machine, the preventive medicines, and raw materials can be mixed and pelleted according to the current epidemic diseases and fish disease occurrence seasons, which can effectively prevent fish diseases and improve the survival rate of aquatic products.
13. Common problems and solutions of the floating fish feed making machine
