Definitions

  • the present specification relates generally to dryers for hay bales, and, in particular, to an air-injection drying system for one or more hay bales.
  • hay is stored in bales, which need to be below a specific moisture level (generally 12%) to prevent spoilage during storage. This is typically done by cutting the hay, then leaving it in the fields to dry prior to being baled. Under ideal conditions, cut hay starts at approximately 75% moisture, which is reduced to around 40% within the first 24 hours and to around 25% in the next 48. However, to get down to 12% typically requires another 72 hours. Therefore, a clear weather window for 5 days is required for harvesting hay. This creates a risk of the hay being exposed to further moisture prior to baling as a consequence of a change in weather patterns. Furthermore, hay left too long may become too dry, leading to a loss of leaves and a reducing harvest.
  • a specific moisture level generally 126%
  • an air injection hay bale dryer using spikes to penetrate the interior of the hay bale.
  • a hay bale dryer comprising: a platform, the platform dimensioned to support the hay bale; a spike rack movably coupled to the platform, the spike rack having a plurality of spikes, each spike having a plurality of slots and each spike dimensioned to penetrate through the hay bale; a fan coupled to the spike rack and operative to blow air through the slots in the spikes, wherein the spike rack is raised to permit loading and unloading of the hay bale, and lowered to permit drying of the hay bale via the air blown through the spikes.
  • a hay bale drying system comprising: a plurality of hay bale dryers, each hay bale dryer comprising: a platform, the platform dimensioned to support the hay bale; and a spike rack movably coupled to the platform, the spike rack having a plurality of spikes, each spike having a plurality of slots and each spike dimensioned to penetrate through the hay bale.
  • the hay bale drying system further comprises a fan coupled to each of the hay bale dryers in line and operative to blow air through the slots in the spikes, wherein each spike rack is independently raised to permit loading and unloading of its respective hay bale, and lowered to permit drying of the hay bale via the air blown through the spikes.
  • a method of drying a hay bale located on a platform to a desired moisture level comprising: lowering a spike rack movably coupled to the platform, the spike rack having a plurality of spikes, each spike having a plurality of slots and each spike dimensioned to penetrate through the hay bale; activating a fan coupled to the spike rack to blow air through the spikes; and raising the spike rack once the process is complete.
  • the present invention is a dryer for hay bales and, in particular, to an air injection dryer for hay bales.
  • the dryer 100 consists of a platform 110 and a spike rack 120.
  • Spike rack 120 may be raised to permit insertion of a hay bale (not shown) as in Figure 1A , and may be lowered to perform the drying process, as in Figure 1B .
  • Each spike 130 in spike rack 120 is coupled via piping 140 to permit air to flow through the piping 140 into spike rack 120 and into each spike 130.
  • Spike rack 120 may be raised and lowered by a hydraulic mechanism, and a spike guide 125 may be attached to the platform 110 to guide the spikes 130 into the hay bale. When lowered, the tips of spikes 130 should not contact the base of platform 110.
  • each spike 130 may be formed from a body 132, with a number of slots 134.
  • the number, spacing and size of the slots 134 is determined by the size of the bale, the estimated average size of the hay flakes within the bale (typically 5 to 6 inches) and the fan pressure and corresponding desired air flow output through the spike.
  • spikes 130 are arranged in 5 staggered rows, in three rows of 16 and 2 rows of 15 (see pattern in Figure 5 ), for 78 spikes 130, with 6 slots per spike 130.
  • different configurations may be used.
  • spike 130 may have a detachable tip 136 and a detachable connector 138 to spike rack 120, to simplify cleaning, however, spike 130 may alternatively be formed as a single unitary piece secured to spike rack 120.
  • Platform 110 includes a bale trap 165 to support the hay bale with a front apron 170 for loading the bale.
  • a bale guide 175 may be provided to align the bale on the platform 110 with the spike rack 120, as shown in Figure 5 .
  • Figure 5 provides a plan view of platform 110 and spike guide 125. As discussed above for a 3x4x8 bale, 78 spikes 130 are arranged in 5 staggered rows (3x16 and 2x15) disposed within the area defined by the front apron 170 and bale guide 175. Figure 6 shows the full assembly of spike rack 120 overlaying the platform 110.
  • FIG. 7 shows a plan view of piping 140 overlaying spike rack 120 and platform 110.
  • Piping 140 should be flexible, to permit the raising and lowering of spike rack 120 without compromising the integrity of piping 140.
  • piping 140 has a Y-split to drive down two sides of spike rack 120, however, a single piping channel may be used, depending on the required airflow, number of spikes, and fan air pressure.
  • a hay bale is loaded onto platform 110 with spike rack 120 raised.
  • Front apron 170 allows the hay bale to be manually pushed onto the bale trap 165, with bale guide 175 acting to keep the bale aligned to the platform 110 and spike rack 120.
  • spike rack 120 is lowered, with spike 130 passing through spike guide 125 and into the hay bale. As shown above, spikes 130 pass substantially through the hay bale, but do not contact the platform 110. With the spikes 130 in place, the drying process may begin.
  • a fan 180 (as shown in Figure 8 ) is activated to force air through the piping 140 and into the spike rack 120 and out the slots 134 in the spikes 130 to dry the hay flakes within the hay bale.
  • spike rack 120 may then be raised to remove the spikes and the dry hale bale pushed through the platform..A new bale may then be placed on the platform as described and the process repeated until all bales are dry.
  • a hay bale could be dried from approximately 25%+ moisture to 12% moisture in 10 to 15 minutes.
  • hay may be baled at 25%+ moisture and dried to 12% moisture via hay bale dryer 100, reducing the harvesting time by 1-3 days, depending on climate conditions.
  • a plurality of hay bale dryers 100 may be connected together in line to a single fan 180 (and, optionally, heater and dehumidifier).
  • the total number of dryers 100 operable is determined by the power of fan 180.
  • the dryers 100 are grouped in line.
  • the piping 140 for each dryer 100 is then connected in parallel along the main line. In testing, it was found the six or more dryers may be connected per channel without a loss in performance, for a total of six or more dryers operating from a single fan 180 as an air source.
  • the plurality of hay bale dryers 100 may be connected to the fan 180 in using one or more Y-split pipes.
  • the overall layout of fan 180 and dryers 100 may be determined by the volume of hay bale to be dried, the space available for loading bales and locating the dryers 100 and, as discussed above, the required airflow through the spikes 130 and power of fan 180.
