In recent years, with the rapid development of the economy, the floating fish feed making machine has followed closely, and the fish feed pellet machine has been sought after by everyone. Then there is a problem, that is, how to choose the floating fish feed making machine. Let’s analyze the three methods of choosing a fish feed pellet machine.
1. Methods to choose a floating fish feed making machine
(1) Appearance quality.
The spray paint on the surface of the shell of the floating fish feed making machine should be uniform and firm, and there should be no paint leakage, sagging and falling off. The chrome-plated parts should be firm and brightly polished, free from peeling and rust. Stainless steel parts should have a smooth surface, no bumps, and should be processed with neat polished patterns.
(2) Assembly and fastening
In addition to checking the fastening of the body and the chassis, the motor (or diesel engine) and the chassis, the floating fish feed making machine mainly checks the assembly quality of the template locking nut and the pellet cutter, and the ring die floating fish feed making machine mainly checks Whether the fastening bolts of the template are tightened. And check the tightness of the pinch roller bracket and pinch roller.
(3) Adjust the gap between the die and the pressure roller wall.
Two layers of paper are stuffed between the pressure roller and the inner wall of the ring die, and it can be pulled out with a little force. After adjustment, be sure to tighten the adjusting nut in time and install the protective cover.
After confirming that there are no foreign objects in the shield and the ring die, turn the ring die by hand. At this time, the driven spindle should rotate briskly, and there is no sticking phenomenon or rubbing sound.
1.Directly observe whether there is beating of the floating fish feed making machine ring die during rotation and whether it will rub against other parts. Open the observation port for feeding the powder into the twisting cage and check whether there is any foreign matter in the twisting cage.
2.Rotate the cage shaft by hand, the cage shaft should rotate smoothly and there is no rubbing noise. Repeatedly open and close the ring-molded warehouse door to check whether it is easy to open and close and tightly closed.
3.Particular attention should be paid to checking the tightness of the joint and the reliability of the locking. The general requirements are: accurate positioning, firm locking, and no leakage of powder.
4.After locking the press chamber door, observe the seam seal of the chamber door from the side. If there is a place where the seal is not tight, the fixing bolts of the door hinge of the warehouse can be adjusted to effectively prevent the leakage of powder.
3. Introduction of floating fish feed making machine
The floating feed extruder machine is a feed processing machine that directly presses pellets from crushed materials such as corn, soybean meal, straw, grass, rice husk, etc.
(1) Classification of floating fish feed pellet machine
Floating fish feed making machine can be divided into ring die pellet machine, ring die pellet machine and counter-roll pellet machine; according to production, it can be divided into: straw feed pellet machine, wheat bran feed pellet machine, soybean meal feed pellet machine, corn straw feed pellet machine , Sawdust feed pellet machine, etc.
A variety of different floating fish feed making machines are classified according to their appearance and production methods.
(2) Main performance characteristics of floating fish feed machine
- Double shaft differential stainless steel conditioner, up to 12 points of steam and 6 points of liquid addition;
- Combined spindle, easy to maintain and repair the bearing housing;
- The screw and the main shaft are connected by involute splines, which are easy to adjust and replace;
- The barrel is embedded with a wear-resistant bushing and is equipped with a return water channel, which can be heated/cooled, and can also directly inject steam or cold water into the barrel;
- Spiral made of special wear-resistant material, large aspect ratio can ensure continuous and stable production of sinking/floating feed of various pellet sizes;
- Convenient and quick die replacement mechanism and online adjustable cutting device;
- Especially suitable for the production of 2~6mm floating pellets.
After the material is extruded by the floating fish feed making machine, it will form soft and soft pellets (the moisture content is 25%~30%). At this time, it is better to use pneumatic conveying instead of elevator.
Because the use of elevators can easily cause the pellets to be broken and improve the pulverization rate; the use of pneumatic conveying can not only quickly form a layer of colloidal coating on the surface of the pellets to reduce the fragmentation of the pellets, but also round the shape of the pellets.
Due to its high moisture content, the material conveyed by pneumatic must enter the dryer for drying, so that the moisture content of the material is reduced to about 13%.
