Abstract

A crop drier comprises a solar collector, tensioned side sheets and end panels. The solar collector may comprise a translucent airtight flexible sheet which is sealed to the side sheets and tensioned over the end panels to form an air chamber which is ventilated by means of a fan (electric or motorized) and heated by solar energy. The air chamber extends over the outer surface of the side panels. The side sheets made be flexible and airtight and may make firm contact with the crop to be dried. The end panels may be rigid airtight panels, their upper edges being convexly curved. One end panel may have an entry hole to ventilate the solar collector. The crop to be dried maybe in the form of bales or in bins. The bales or bins maybe placed on a ventilation floor or pallet to allow drying air to exit from the lower surface of the bales.

Description

I
Title:-SUNBIN The invention relates to a sheet-wrapped enclosure used for the purpose of drying herbage or grain in round or rectangular bales or bins. The bales or bins are tightly assembled in one or more parallel rows. The enclosure consists of tensioned side sheets, a translucent cover sheet and a rigid end panel sealing each end.
The airtight side sheets are tensioned vertically to the sides of the bales or bins with adjustable ties. These sheets tightly wrap the opposite vertical sides of the bales or bins. These sheets will be known as the side sheets.
Page 5 figure (1) (C) shows the tensioned side sheets for round bales Page 6 figure (2) (B) shows the tensioned side sheets for rectangular bales or bins The upper and lower surfaces of the bales or bins will not be wrapped. This allows air to flow freely through the crop from the upper surface to exit at the lower surface.
Both ends of the tightly packed rows of bales or bins are sealed with rigid airtight end panels to prevent air escaping. The upper outer edges of the end panels are shaped as a continuous curve to create an air seal when flexible material is tensioned over them.
These panels will now be known as the end panels.
Page 5 figure (1) (D) and (1) (E) shows the end panels for round bales Page 6 figure (2) (A) shows the end panels for rectangular bales One of the two end panels has an air entry ventilation hole through which air enters the enclosure.
A translucent, airtight sheet is attached to the side panels. This sheet extends over the side panels, over the entire upper surface of the drying crop and over the end panels.
This sheet is sealed to the side panels and tensioned over the end panels to form an airtight chamber at the top of the bales or bins. This sheet is known as a solar collector.
Page 5 figure (1) (B) shows the solar collector for round bales Page 6 figure (2) (B) shows the solar collector for rectangular bales The solar collector is inflated by air entering through the end panel air duct. Solar heat will then warm the air within the solar collector before it passes through the baled or binned crop to the atmosphere.
The free solar heat input is expected to increase the fan energy input by a factor of thirty. This heat will create warm drying air during a normal harvesting season and avoid the need for additional supplementary heat.
The solar collector overlaps the side panels to equalise the air pressure between the outer and inner faces of the tensioned side panels. This added external pressure on the side panels will increase the contact of the side panels with the bales or bins.
The bales or bins will be assembled on pallets or a ventilated floor to allow a free exit for air from the lower surface of the drying crop.
The Sunbin can be operated on any open, level, southern aspect location if fan ventilation is available.
The Sunbin can be easily dismantled into manageable sections for moving to a new location or storage.
The Sunbin uses free solar energy, will dry crops cheaply and quickly, is a low cost alternative to field drying, fuel fired drying, sealed silage storage or refrigeration chilling. It will produce a dry crop for safe storage with high value and increased digestibility.

Claims (4)

  1. Title:-Claims 1 The Sunbin crop drier comprises a solar collector, tensioned bale or bin side sheets and end panels. When assembled they form a solar heated air chamber to dry baled or binned crops. The tensioned side sheets ensure that air from the solar collector passes through the baled or binned crop. This system offers a low cost effective alternative to existing ventilated crop drying systems.
  2. 2 The solar collector according to claim 1, is a translucent airtight flexible sheet which is sealed to the side wrapping sheets and tensioned over the end panels to form a fan-ventilated solar heated air chamber. This air chamber extends over the outer surface of the side panels, over the upper surface of the assembled bales or bins and is tension sealed at both end panels.
  3. 3 The side sheets according to claim 1, are flexible airtight sheets, tensioned vertically on opposite vertical sides of the bales or bins to be dried. They make firm contact with the bale or bin to form a passage for air to travel down through the crop from the solar collector.
  4. 4 The end panels according to claim 1, are rigid airtight panels tensioned to the ends of the rows of bales or bins to prevent air escaping. Their upper edges are shaped as a continuous convex curve to create an air seal when the solar collector is tensioned over them. One end panel has an air entry hole to ventilate the solar collector.The Sunbin according to claim 1, requires the bales and bins to be assembled on a ventilation floor or pallet to allow drying air to exit freely from the lower surface of the bales or bins.
