Abstract
The present application is directed to a system and processing method for fractionating pre-formed forage hay bales into a fractionated leaf portion and a fractionated stem portion. More particularly, the system involves grinding, chopping and shredding bales, and fractionating the chopped and shredded bales using a shaker table and grate assembly, into a fractionated leaf portion and a fractionated stem portion using a shaker table. The resulting fractionated leaf portion and fractionated stem portion can then be further processed into pellets for animal feed products, or the fractionated stem portion can be re-baled. Pelletization includes customizing the size of the pellets and the addition of additives to the pellets according to customers specifications for customized animal feed products. Pellets derived from the fractionated leaf portion and the fractionated stem portion are then packaged, typically in bags, for storage and transport.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0045] As required, the detailed embodiments of the present Forage Feed Hay Bale Fractionation System and Feed Product Processing Method 10, 110 and 210 are disclosed herein, however, it is to be understood that the disclosed embodiments are merely exemplary of the design that may be embodied in various forms. Therefore, specific functional and structural details disclosed herein are not to be interpreted as limiting, but merely as basic for the claims and as a representative basis for teaching one skilled in the art to variously employ the present design in virtually any appropriately detailed structure as well as combination.
[0046]
[0047] During STEP 2—Fractionation, a fractionated stem portion (FSP) 30 is also generated for further processing and STEP 6—Stem Processing is accomplished in either of two separate options (see
[0048]
[0049]
[0050] The bale grinder loading table has been modified to include a false floor that can be both raised and lowered and a chain drive built in to the floor in order to efficiently load and move alfalfa bales into the bale grinder. An alfalfa bale is placed on the elevated false floor and pushed into place 40. The false floor then drops below the chains of the chain drive mechanism, allowing the chains to securely grab and drag the bale into the grinder processor 42.
[0051] Bale binding netting and/or twine must be removed from alfalfa bales before being introduced to the chopping knives of the grinder. Once bales are in place on the grinder table, plant employees in safety harnesses climb on top of bales to cut and remove twine. Twine is manually cut with a handheld knife and the ends of the six or more strands are gathered and knotted together. This bundle of twine is then pulled from the bale using an overhead winch on a cable 44.
[0052] The current grinder system has three or more internal drums, with a plurality of chopping knives on each drum. For example, a grinder set-up such as the Warren & Baerg style of grinder may be employed. The drums rotate, and the chain drag system on the floor of the table propels the baled alfalfa to the chopping knives. The rotating multiple drums with a plurality of chopping knives spin rapidly which allows the Warren & Baerg style bale grinder/processor to mechanically beat the alfalfa leaves off of the alfalfa stems while at the same time chopping the alfalfa stems into 3 inch lengths 46, thus beginning the fractionization process. Once chopped and shredded by the grinder, ground alfalfa moves from the grinder to the shaker table 48 on a conveyor.
[0053]
[0054] Elements of the shaker table include: A table set on an angle with the higher elevation being closest to the chopper/grinder feed conveyor. Through gravity and the shaking motion, the chopped product travels along the table. Metal openings on the table's surface allow product of a specific size to drop down through the table 56 to a collection bin, then one or more augers or conveyors convey the collected fractionated leaf product out of the collection bin, which is then sent to a hammer mill 56.
[0055] The shaker table is made with an adjustable grate assembly to be able to modify the expanding metal openings according to product needs; larger openings allow more stems to be added directly to the leaf fraction at this step while smaller openings allow fewer stems to fall into the leaf fraction. This expanding shaker system allows for protein customization in the final product according to each individual customers' animal feed leaf/stem ratio specifications. It is anticipated that one or more grates may be used, and the opening size is adjusted by movement of the grates relative to each other (see
[0056] In an alfalfa plant, leaves are consistently about 31% protein and stems are about 12% protein. In addition to protein, both leaves and stems have values for fiber, vitamins and other nutritional qualities that may be used to create a custom blend for final alfalfa products. In alfalfa, leaves are leaves. Their nutritional value is consistent throughout the plant's growing cycle and may therefore be considered a constant when calculating nutritional value of leaf/stem mixes. The variable in alfalfa plant nutritional value is found in the stems—nutritional composition of alfalfa stems depends on many factors, including maturity, height, and lignification. The present embodiment of the adjustable shaker table, with respect to speed of shaking and size of grate assembly opening, allows for customization of the leaf-stem ratio in a given feed product processing.
[0057]
[0058] STEP 4—Leaf Fraction Pelletization. Pelletizing the hay leaf fraction is a way of densifying the product. Depending on the die used in the pellet mill, the size and length of the alfalfa pellets may be customized according to customer animal feed product specifications 62. Any additive customization happens during the pelletization step 64. The alfalfa leaf fraction can be sold as a straight product or be enhanced with nutritional supplements and other additives per customer animal feed product requirements.
[0059] STEP 5—Pellet Packaging. Pellets are then packaged 66. Pellets are currently being bagged, which has proven to be a time-tested and effective way to store and transport pellet animal feed products.
[0060]
[0061] Option 1—Stem Fraction Re-baling 72. A Freeman baler is currently best option due to operational needs, however, other baler may be used as well. Stems are fed into the baler chamber 74. Once the chamber is filled, the product is lifted up into the bale chamber and pushed into the bale by the plunger 76. Currently, the Freeman baler is the only agricultural baler with the ability to create quality bales without running at full capacity. Other balers run the plungers continuously which leads to weak structural integrity of bales when product is fed slowly into the machine, which is the case here with the re-baling of the fractionated stem portion.
[0062] Steam is introduced to the stems as they are re-baled 78. Stems are dry when they are brought into the plant. Steam is introduced to the stems, bringing them up to ˜13% moisture. This moisture level allows the baler to create beautiful, tight, solid bales. Re-baled stem product bales are ready for storage and transport 80.
[0063] Option 2—Stem Fraction Pelletization 82. Stems are sent to a hammer mill for sizing 84. Sized alfalfa stem fraction is sent from hammer mill to pellet mill 86. Pelletizing the alfalfa stem fraction is a way of densifying the product. Depending on the die used in the pellet mill, the size and length of the alfalfa pellets may be customized according to customer specifications. Any additive customization happens during the pelletization step. The alfalfa stem fraction can be sold as a straight product or be enhanced with nutritional supplements and other additives per customer requirements 88. Pellets are then packaged 90; pellets are currently being bagged, which has proven to be an effective way to store and transport pellet products.
