Double Press
Natural Big Bale Press

The System The Natural Big Bale Press is designed to maximize efficiency in processing field big bales for export. Double Press has achieved an impressive machine with a relatively small footprint and a significantly reduced manufacturing cost. With bolted construction, custom configurations require no redesign.
Bales are loaded, cut, pressed, and sleeved with efficiency. This reduces the handling normally required at the back end, as well as the labor needed to run the operation. The process is automatically controlled, or can be manually controlled by the operator.

Loading Three big bales can be loaded at a time onto the infeed system which feeds them into the cutter. An 8” cylinder pushes a bale through the vertical cut station where knives slice the bales in halves or in quarters between the twine, maintaining the bale’s integrity.

Twine Removal At the operator’s station the product can be inspected for quality and consistency, and the twine manually removed.

Weighing Prior to compression the hay passes on to an infeed scale that selects a predetermined amount of product to be compressed.

Press The hay is then compressed with a single 18” cylinder, reducing the bale length to about 27”. Compression power is supplied either through diesel or electric motors.

Side Ejection The compressed, full-weight bale is side-ejected, and may be sliced horizontally before arriving at the sleeving station. The vertical slicing before compression coupled with the horizontal slicing after compression yields half-cut bale sizing inside the sleeve. The customer realizes easier handling, shorter fiber length, and historically consistent package size.

Sleeves An operator places a woven polypropylene sleeve around the ejection port, which traps and holds the bale as it is being ejected. The finished size is 36”H x 48”W x 44”L. This allows it to be placed three bales high and two wide in a high cube container for a total of 52 bales.

Bale Discharger The sleeved 1000-1100 lb bale is moved away from the ejection port and accumulated for easy access by the clamp operator who can set bales aside or load them directly into a container.

Control The system is controlled by the press operator via the control panel. As with other Double Press machines, the primary mode is “Automatic”. Each of the 9 steps can be manually controlled, making set-up and maintenance an orderly and repeatable process that can be completed by a trained employee.

What's In It For You? By building a simplified machine that processes big bales directly into sleeved compressed bales, Double Press provides customers big machine efficiency at a fraction of the cost, and eliminates the need for strapping and wrapping machines and material.

The process provides a 3-Tie/Half-cut natural product in a 1000 lb (450 kg) package at a rate of one container per hour.
