The major feature of the fish feed drifting pellet making machine is to straight extrude puffed food. Normally, grains, potatoes or beans are made use of as the major basic materials.
After being extruded by thefloating fish feed making device, under the problems of high temperature and high pressure, the item is blown by utilizing the pressure difference inside as well as outside the machine
The straight extrusion kind puffed food typically does not consist of lead, and also currently the fish feed drifting pellet making device is extensively utilized in the food industry. So just how much do you know about the floating fish feed extruder? The fish feed drifting pellet making machine has a pair of screws and also a screw sleeve, which have the features of mixing and working.
After the raw product gets in the extruding tooth cavity, the material goes through extrusion, rubbing and shearing between the screw sleeves, and also the inner pressure remains to increase, as much as 4Mpa, and also the temperature level continues to rise, as much as 140 ℃.
Within 3-7s, the temperature and pressure of fish feed drifting pellet making equipment surge sharply, as well as the tissue framework of the material adjustments, which further gelatinizes the starch, denatures the protein, damages the crude fiber, and eliminates dangerous microorganisms such as Salmonella.
The high-temperature and high-pressure material comes out of the discharge port, as well as its pressure is unexpectedly released in an instant, as well as the moisture is partly flashed.
1. The framework of floating pellet making machine.
The feeder is to make sure uniform and steady feeding, as well as readjust the feeding quantity according to the rated current worth of the electric motor of fish feed floating pellet making device. Normally, an cpm pellet mill -magnetic speed-regulating motor or a frequency converter is used to readjust the rate, as well as the feeding amount of the feeder is changed.
wood pellet mill for sale tooth cavity of fish feed floating pellet making maker is composed of screw, screw sleeve, layout, card bone and so on. The screw as well as screw sleeve are combined in areas, the compression level can be adjusted according to the kind and also requirements of the extruded feed, and the extruded degree of the extruded feed can be changed;
The fish feed drifting pellet making machine is separated right into 3 areas in regards to collapse degree according to work and position:
① Feeding area: This section of floating fish feed machine has a large screw pitch, and generally shares and also compresses the product to ensure that the product fills up the spiral groove;
② Compression area: The screw groove of this section modifications from deep to shallow along the product moving direction to compress the material;
③ Extrusion area: the screw groove is shallower, the pitch gradually becomes smaller, the extrusion pressure can reach 3.0-10Mpa, and also the temperature level can get to 120-150 degrees Celsius. This section has the greatest stress and greatest temperature, so the wear of the screw and screw sleeve is additionally one of the most serious.
The outlet of the extrusion section is a template, the form of the layout is made with different die holes according to the needs of various feeds, the material is extruded from the die opening of the theme and also enters the atmosphere, the pressure and temperature level drop greatly, and its quantity expands swiftly, the water rapidly evaporates, dries out and strengthens to become an extruded product.
2. Fixing of fish feed drifting pellet making maker
Turn the fish feed drifting pellet making machine on-site control switch to the quit state during maintenance;
The inside and outside of the fish feed drifting pellet making maker must be cleansed after each change, particularly the material must not be maintained in the puffing chamber, so as to prevent it being challenging to tidy up after cooling and also pile;
The big wheel of the primary shaft of the puffing chamber must be cleansed frequently, as well as not way too much dirt, or else the pulley-block will certainly be out of balance and also the puffing chamber will certainly vibrate;
The main bearing of the expansion chamber is oiled with lubricating oil, and the bearing of the fish feed floating pellet making machine conditioner as well as its transmission tool as well as other bearing components are oiled with grease;
The main bearing needs to be replaced with brand-new oil regularly. After 250 hours of work, all brand-new oil has to be replaced;
Other bearing components, every 48 hours of work, grease is infused once;
The chain transmission device on the vapor conditioner need to be lubricated often;
The oil in the reducer of fish feed floating pellet making device ought to be regulated at the adjusted oil degree, and also the brand-new oil ought to be changed after 250 hours of procedure;
When getting rid of the screw head, do not knock it hard;
Constantly maintain the fish feed drifting pellet making machine and also its environments clean.
