In addition to the continuous reform of the Food Extruder
Machine industry, it also has a lot to do with the support of national
policies. Relevant experts suggest that if the country can use plastic machines
as machine tools as the basic machinery of the industry and as the national
equipment industry It is an important part of the advanced plastic machinery,
which gives special support and preferential policies like CNC machine tools to
promote the plastic machinery industry to play a more significant leverage role
and make greater contributions to the development of China's equipment
industry.
Breakfast Cereals Processing Line
Breakfast Cereals Processing Line advantages：
1. High reliability The screw compressor has few parts and no wearing parts,
so it operates reliably and has a long life. The overhaul interval can reach
40,000 to 80,000 h.
2. Easy operation and maintenance Screw compressors have a high degree of automation, and operators do not need to undergo long-term professional training to achieve unattended operation.
3. Good power balance Screw compressors have no unbalanced inertial force,
and the machine can work smoothly and at high speed, and can achieve baseless operation.
4. The adaptable screw compressor has the characteristics of forced gas transmission, the volume flow is almost not affected by the exhaust pressure,
and it can maintain high efficiency in a wide range. It is applicable without any change in the compressor structure For a variety of working fluids.
5. Multi-phase mixed transmission There is actually a gap between the tooth surfaces of the rotors of the screw compressor, so it can withstand liquid impact and can pressure-feed liquid-containing gas, dust-containing, and polymerizable gas.
I would like to share with you the six common causes of the wear and tear of the Breakfast Cereal Machine screw barrel.
1. During extrusion production, because the process temperature is too low or metal foreign substances are mixed with the material in the barrel of the extruder, the working torque of the screw will suddenly increase. This torque force exceeds the strength limit of the screw, which will cause the screw.
Twisted off.
2. If there are fillers such as calcium carbonate or glass fiber in the material, it will increase the wear of the extruder screw and extruder barrel.
3. The extruder screw rotates in the barrel of the extruder to extrude the material. The long-term friction between the screw, barrel and material will
inevitably cause the wear of the barrel and the screw. The inner diameter of the
barrel will gradually increase and the outer diameter of the screw will gradually decrease. In this way, the clearance between the screw and the barrel
will gradually increase as the two gradually wear.
4. Improper operation, unstable process temperature control, a large amount
of HCI gas is often released when the extruded material is decomposed, such as
PVC, which exacerbates the corrosion of parts.
5. The heat treatment hardness of the working surface of the extruder screw or barrel does not reach the required value, which will accelerate the wear of
the two parts.
6. Improper selection of materials for the screw and the barrel of the extruder makes the working strength of the two parts insufficient and shortens
the working life.
