Why is the trough type flipping machine designed for "forward"
flipping?
The design and rotation direction of the blade roller of the trough
flipping machine are precisely calculated, and its "forward" working mode aims
to achieve the following core functions:
Crushing and mixing: The cutting tool cuts into the material at a specific
angle, and during the process of throwing the material backwards (relative to
the direction of machine advancement), it can effectively break up clumps, make
the material loose, and fully mix the outer layer with the central layer, new
material with old material.
Uniform scattering and fluffy stacking: After the material is thrown
backwards, it will form a uniform and fluffy stacking profile. This creates the
optimal porosity, which is crucial for oxygen transport, water evaporation, and
heat dissipation in aerobic fermentation.
Controllable displacement: With each forward flip, the material undergoes a
cohesive and controllable displacement (usually a few meters) along the length
of the fermentation tank, which helps the material move gradually throughout the
fermentation cycle.
What would happen if the 'reverse' flip occurs?
Assuming that the trough type flipping machine is reversed while the blade
roller is reversed (or even if not reversed), attempting to achieve "reverse
flipping" will result in:
Material stacking and compaction: The material will not be effectively
thrown backwards, but may instead accumulate and be compressed in front of the
knife roller, resulting in the material being compacted. This is completely
opposite to the "fluffy" state required for fermentation.
Uneven flipping: Unable to form an effective throwing arc, the material in
the central area may not be processed, while the material at the edges may be
pushed to the edge of the trough, resulting in extremely uneven
fermentation.
Impact on fermentation process: The porosity of compacted materials drops
sharply, oxygen cannot enter, heat is difficult to dissipate, and moisture
cannot be discharged. This can cause a slowdown in fermentation rate, abnormal
temperature (local overheating or overall low temperature), and even create an
anaerobic environment, emitting a foul odor.
Increasing equipment load: The knife roller and hydraulic system may
operate under non design conditions, encountering greater resistance, resulting
in increased energy consumption, accelerated tool wear, and even damage to
transmission components or machine shutdown.
Displacement out of control: The direction and distance of material
movement become uncontrollable, disrupting the material advancement plan of the
entire fermentation tank.
So, under what circumstances would a "reverse" operation be considered?
Usually, the term 'reverse' mentioned in the operation only refers to the
overall walking direction of the machine, not the flipping action itself. For
example:
At the end of the flipping operation, return the machine to its starting
position with no load.
When encountering abnormally hard or tangled objects during the flipping
process, it is possible to briefly reverse to avoid damaging the equipment, but
this is not "reverse flipping of materials".
What is the correct solution?
If you feel that materials need special handling in a certain area (such as
corners or uneven stacking), the correct method is:
Plan the path and number of forward flips.
At points that require special handling, stop the trough type flipping
machine and perform multiple local, forward flipping operations instead of
attempting to reverse.
For design blind spots, other auxiliary tools (such as forklifts) should be
used for pre sorting, and then the flipping machine should be used for regular
operation.
