Single-screw electric small dry type fish feed pellet extruder for small scale is used for processing for dogs and cats (pet food), birds, piglets, frogs, sinking and floating aquatic feeds for fish. Which is high and new technical program as to catch the developing pet food market. CE certificate best price floating aquarium fish feed pellet food making machine mainly use maize, fish powder, meat powder and some food additive as main raw material, through mixing, extruding, roasting, flavoring to get the final puffed pet food.  The dry puffing process saves the feed conditioner and its associated steam boilers and pipes relative to the wet process. The equipment is safe, simple, and has low investment and wide application range. Puffing and granulating the full-price pet feed can gelatinize the starch, denature the protein, eliminate and passivate the anti-nutritional factors, and inactivate the harmful microorganisms, thereby improving the digestibility, improving the feed hygiene and prolonging the shelf life. It's fully automatic, high capacity and with different of shapes.
The working principle of the fish feed extruder:
The dry type fish feed extruder has a screw and a threaded sleeve, which have the function of mixing and twisting. After the raw material enters the expansion chamber, the material is squeezed, rubbed, sheared, etc. between the screw sleeves, and the internal pressure is continuously increased, up to 4Mpa, and the temperature is continuously rising, up to 140 degrees Celsius. During the period of 3-7s, the temperature and pressure increase sharply, and the structure of the material changes, which further gelatinizes the starch, denatures the protein, destroys the crude fiber, and kills harmful bacteria such as Salmonella. The high temperature and high pressure materials come out from the discharge port, and the pressure is suddenly released in an instant, and the water is partially flashed. After cooling, the material is loose and porous, and the expanded material is in the form of agglomerates, flocs or coarse chips.
The structure of the Single-screw electric small dry type fish feed pellet extruder for small scale:
1. The feeder is to ensure uniform and stable feeding, and adjust the feeding amount according to the rated current value of the extrusion motor. -- Generally use the electromagnetic speed regulating motor or inverter to adjust the speed and change the feeding amount of the feeder. The outlet of the feed hopper is usually fed by a spiral auger to the extrusion section.
2. The puffing chamber is composed of a screw, a screw sleeve, a template, a card bone and the like. The screw and the screw sleeve are combined in stages, and the degree of compression can be adjusted according to the type and requirements of the expanded feed to change the degree of expansion of the expanded feed.
3. The expansion mechanism is divided into three sections according to the action and position in the collapse degree: feeding section: the screw pitch of this section is large, and the material is mainly conveyed and compressed to make the material fill the spiral groove. Compression section: The screw groove of this section of the screw is deeper and shallower in the direction of material change, and the material is compressed. Extrusion section: the groove is shallower, the pitch gradually becomes smaller, the pressing force can reach 3.0-10Mpa, and the temperature can reach 120-150 degrees Celsius. The pressure is the highest and the temperature is the highest, so the wear of the screw and the screw sleeve is also the most serious. The outlet of the extrusion section is a template. The shape of the template is designed into different die holes according to the requirements of different feeds. The material is extruded from the die hole of the template, enters the atmosphere, and the pressure and temperature drop rapidly, causing the volume to expand rapidly. Rapid evaporation and dehydration solidification becomes a puffing material.

Fish feed pellet machine can be divided into 2 types: small Dry type extruder and Large wet type extruder fish feed pellet machine.

Dry type: The dry type fish feed pellet making machine also called  single-screw extruder. It is usually used for small-volume feed production, The single-screw extruder has a relatively stable work and strong shearing force, but it is easy to block the discharge hole. It needs to be manually disassembled and cleaned every time it is used. The heat distribution is uneven when the material is extruded, compared with the wet twin-screw extruder. The curing uniformity is poor, the moisture content is low, and the scope of application is limited. It is mainly used for processing raw materials, poultry and farmed feed. Nomally installed in floating fish feed pellet line.


Wet type: The wet type fish feed pellet making machine. It is equipped with a preparation device to ripen the feed raw materials, and is usually used for large-volume production of feed lines for use with boilers.it can produce neat and uniform beautiful ultra-small diameter particles, has good self-cleaning effect, no need to disassemble, good ripening degree, high water content, wide application range, can produce high oil, high moisture materials, mainly Used in aquatic feed, pet food and animal feed.

Product features
 
1.Do not need vapour, lower the cost :In the case of the same feed, the price of self-made feed is 30%-60% lower than the market price.
2.Wear-resisting screw and sleeve:High temperature resistant alloy steel material treated by hardening, has advantages of abrasion resistance and long life.
3.Feed floating time more than 24hours:With this machine, the inflated feed particles are tidy and smooth, keep floating over the water for more than 24 hours.
