Small Bale Haylage Packer
Packaging
system that turns large bale round / square bale haylage into weighed manageable
20 kg airtight packs at a rate of approx. 60/70 packs per hour with only two
operatives.

Bale Breaking
System
Shown above is the bale breaking system which comprises
of a spiked conveyor to pick up the large bale haylage with a special
doffing unit to thin the material ready for weighing and feeding. The
walking floor system which typically holds up to four large square bales
feeds the large bales at a constant rate up to the spiked bale breaking
conveyor. The large baled haylage is placed on the walking floor system and
the wrapping and twine removed and the machine automatically feeds the
material through the system. Four large bales would generally be sufficient
for one hour of running.
Round Bales.
For round bales we would usually not use the walking
floor system but would add a round bale haylage unrolling system and small
feed conveyor before the spiked conveyor. The bale unrolling system is only
suitable to unroll one bale at a time and would require a new bale adding at
intervals of approx. 10 to 15 min.

Weighing System
To ensure consistency of the finished product the
material is fed onto a weigh conveyor that will weigh the haylage material
before the packing process. The weighing conveyor generally would be set to
produce a finished pack weigh of 20 kg, The bale weight when packing dry
material would be reduced accordingly to suit the dry material volume. the
system would be capable of packing other materials i.e. Straw, Hay, shavings
etc. the bale weight would be adjusted accordingly to possibly 10 / 15 kg's.

Packing System
The packaging system comprises of a
hydraulic bagging press with a four ram system to compress the loose haylage
into the small compressed packs. The total tonnage used is approx. 15 tons
to ensure that all the air has been expelled from the material being packed.
The system has a total compression ratio of approx. 20:1. There is no
requirement for the finished pack to have a vacum pump to remove any air as
the action of the compression of the machine removes enough of the air to
prevent the material going off. |

The Finished
product
The finished product is packed into a
plastic bag which has been sealed with a special double seal and a built in
valve system to allow air to be released from the pack but not allow air to
re-enter the bag. This ensures that the haylage material inside the bag is
of a high standard and ensures a prolonged shelf life.
The finished 20kg pack is compact with
a general size of 600 x 400 x 220 mm which lends itself to maximise storage,
Transport and handling.

With over 15 systems
currently installed through the UK and Europe the system has been in the field
for over three years and the process is tried and tested and has been producing
top quality small bale haylage over this period.
