Blockage Reason Analysis & Solution of Fish Feed Extruder

During the process of fish feed pellets production, it is vital that fish feed extruder can produce pellets normally and safely because pellet preparation totally depends on the pellet making machine. As one of the primary key equipment for feed enterprises or fish farmers, the good running of fish feed extruder pelleting machine directly influences economic benefits of feed plants. However, in the actual production, it is not difficult that the extruder is blocked before products expelled from die hole, causing the common pelletizer blocking phenomenon.

Inappropriate gap of the extruder screw and puffing chamber:
In the process of extruding, raw materials are transported from feeding hole to the whole extruder chamber via screw, so the clearance between the extruder screw and puffing chamber is very important for fish feed making.

The influence of steam
In general, the major elements of the most ideal production condition in the producing process of pellet fish feed contain the suitable raw material and water content, the excellent steam in quality, and the sufficient hardening and tempering time. Using dry saturated steam for granulation properly can help to efficiently increase the yield of fish feed extruder and improve the quality of fish feed pellets at the same time.

The effect of tempering
As is well known, for pellet feed meeting the competitive demands of market, suppliers must make sure the quality of fish feed pellets are excellent. Before pelleting, the tempering effect of materials is of great concern because it directly affects the production capacity and pellet quality of fish feed extruder machine. Especially, the stability in water of special-type aqua feed is also an important index, if materials cannot get enough tempering and ripening before pelleting, then the index of water stability would be hard to guarantee.

Choosing tempering equipment in line with the technical requirements can make materials fully stirring and mixing with steam within conditioner, achieving the effect of softening materials and pasting starch, beneficial to powder compacting and shaping and producing the products up to standard. The conditioner should have heat preservation, heating and moistening function for a long time, which can make sure materials fully meet the tempering requirements, improving the surface appearance and inner quality of pellet feed, and enhancing the feed stability in water.
