Abstract
Crop drying apparatus comprises a composite outer cover 1 for covering bales or bins of straw, hay, herbage etc and two end panels. The outer cover comprises an impervious/impermeable, translucent outer membrane 2, two impervious non-translucent inner membranes 3 and two impervious tensioning eyelet extensions 4. The inner membranes are joined together with a porous/permeable membrane 15 to form an enclosure within the outer cover for the purpose of heating air. The enclosure is tensioned over the bins or bales with the porous membrane located over the top of the bins or bales. Both ends of the outer cover extend over the end panels to form an air-tight seal. Air in the enclosure is heated by solar energy and passes through and dries the herbage, the moist air being exhausted to the atmosphere from underneath the bins or bales.
Description
S:.c..Ir9pDTup Crop Qy.pgftpparatus Inc.p ating SoIa1Hea: Backgpy4to the inventlo 1 llerbage may be dried or have surface moisture removed to reduce decay after harvesting. Field drying with ambient air is the preferred low cost form of drying but if ambient air is unsuitable to dry herbage, the drying process is prolonged and herbage quality deteriorates. In these conditions it is normally desirable to accelerate drying by mechanically ventilating the herbage with heated air. Mechanical ventilation requires the carting of the herbage to the drier and the provision of drying apparatus and heating fuel. The invention aims to reduce these costs by being transportable, operating at the harvest location, and using solar heat within a low cost apparatus.
2 For ease of transport and assembly, the drier has no constructed walls, internal support structures or rigid air ducts.
3 The costs are reduced by combining five membranes in an outer cover. The membranes enclose the herbage, contain air within an enclosure, distribute air through the herbage, provide solar heating within the enclosure and also give weather protection for the drier.
4 Herbage is normally packaged in bales or bins for ease of handling and storage. The herbage can be fibrous, granular material, roots, chipped wood or chopped seaweed.
Hereafter all these crops are referred to as herbage. The bales or bins will be rectangular pallet bins, rectangular bales on paliets, or round bales on pallets. Hereafter all these containers will be referred to as a bin. The bins of herbage will be assembled in a continuous row and enclosed by an outer cover and impervious end pieces for ventilation drying.
S A large area of solar collecting membranes is incorporated in the outer cover to provide sufficient heat to raise the temperature of the large volume of air required for herbage drying and provide a free alternative for fuel fired heating.
S The power and cost to operate mechanical ventilation equipment is reduced by reducing the air pressure required to ventilate the herbage. This is achieved by havIng a low: depth and large area of herbage within the drier.
Prçipai ObjenJw..
7 The drier is designed to be low cost and mobile with solar heating and flexibility to dry herbage in pallet bins at remote locations with a small power source.
8 The drier is designed to be easily assembled and self supporting to operate on any flat, sunlight exposed area of ground with no need for supplementary building structures, internal support structures or rigid air ducts.
9 Drier components consisting of bins of herbage, two impervious bin end pieces and the outer cover are assembled and connected to a source of pumped air to dry herbage.
The principal objective is achieved by ventilating herbage within an assembled continuous row of bins and end pieces coveted and enclosed by: a multi membrane outer cover
