Description
COIR PITH
The invention relates to coir pith. Coir pith is the residue from coconut husk, i.e. the residue remaining after the fibrous material is removed for rope manufacture and the like.
Coir pith is normally dried and compressed into briquettes, blocks or bales for export to Great Britain by the producers. The term briquettes will be used hereinafter to denote all these prior art forms of core pith.
The briquettes have for example previously been reconstituted by the addition of large volumes of water to produce a product for use as a peat substitute.
We have discovered that if the briquettes are reconstituted back into the original dry form, the resultant coir pith dust has a number of useful and sometimes unexplained uses.
Accordingly, our invention comprises taking a quantity of coir pith, for example in the form of briquettes and converting the coir pith into coir pith dust.
Preferably, the coir pith is converted to coir pith dust by a milling process.
The coir pith may be milled utilising a cutting head or milling head.
Specific machines to convert coir pith briquettes to coir pith dust may include the following : (a) a rotary knife or blade cutting against a stationary knife or blade or a
combination of a number of knives or blades in the horizontal and
vertical planes.
(b) a guillotine providing a chopping process to produce samples of desired
lengths and thicknesses.
(c) a hammer mill with a number of rotating flails or hammers which push
the resultant coir pith dust through stationary concave screens.
(d) a tumbling machine comprising a perforated rotating drum with paddles
or blades attached to an inner wall. By rotation and contact with the
wall and paddles the briquettes are broken down and the coir pith dust
exuded through the perforations in the wall of the drum at a required
size.
All the above processes may be carried out in the dry state, thus differentiating between motive processing and simple water expansion methods of reconstitution. The coir pith dust resulting from our process retains its dry form and further retains all its absorbent qualities.
After the above processes have been undertaken, it may be desirable to incorporate small amounts of water, oils, essences, silicone based surface tension adjusters, enzymes and digesters or naturally occurring products to tailor the coir pith dust to specific applications. It may also be incorporated within mats or blankets to produce a floating membrane.
The reconstituted coir pith dust, with or without incorporations, may be further refined by riddles, mixers and screens to produce consistently graded products.
We have discovered that coir pith dust has excellent hydroscopic and hydrophobic qualities and accordingly our invention also comprises a method of absorbing liquids by the application of the processed coir pith dust in any desired form.
The products produced by the above methods are many and various and may include the following :1. Sport : a dry application of coir pith dust may be applied to the goal
mouth of sporting pitches, such as football or hockey pitches, to render
them less wet and to improve the playing surface, or as a covering for
frosted areas.
2. Motor sport : applied to wet or oily track surfaces coir pith dust
efficiently absorbs any liquids making the track usable quickly and
safely.
3. Cricket : after a shower coir pith dust can be applied to the wicket ends
and run ups so that the ground can be quickly dried out and made safe
to allow play to resume with the minimum of delay or resultant
damage.
4. Equestrian bedding : to dry up stalls/boxes with the resultant waste
material being suitable for garden dressing or manure.
5. General fluid absorbent : coir pith dust spread on spillages of most
generally available fluids absorbs the fluids much more quickly than
any other commercially available clay based products and the resultant
waste material is much lighter.
6. Gardening : coir pith dust either alone or combined with other
naturally occurring commodities can be used as a general soil improver
or fertiliser.
7. Horticulture: coir pith dust can be used as a medium in its dry form
to initially to carry seeds and once wet as a growing medium giving
germination and moisture retention. Coir pith dust when blended with
denser materials such as calcified seaweed or sand increases the
bulking and improves the handling qualities of the other products
rendering them more attractive to the end user.
8. Pet litter : unlike other commodities, coir pith dust dries naturally and
this extends its longevity in use. When blended with other natural
products, the combinations are ideally suited for pet litter and an
additional plus point is that it can be disposed of to naturally degrade
on the garden.
9. Poultry and animal farming : coir pith dust applied to areas around
troughs absorbs excess moisture improving animal health and making
cleaning easier.
10. Packaging : coir pith dust in either its dry form or pressed with the
addition of moisture into pre-formed trays is a natural alternative to
polystyrene with none of the subsequent disposal problems or re-use
possibilities.
11. Insulation : in its loose form or reconstituted into a board or spray
applied form, coir pith dust has high insulation qualities.
12. Anti-slip : coir pith dust applied to wet or slippery surfaces has the
effect of increasing friction thereby reducing the slip factor.
13. Cleaning agent : in various forms the coir pith dust can be used as an
agent for the cleaning of oxidised deposits from soft metal when low
abrasion is a requirement.
14. Pelleting : for some of the above applications, the coir pith dust may
be produced in a pelletised form.
A specific example of the invention will now be given.
I have established that 1 kg of coir pith can be milled by our process to produce 5 litres of coir pith dust. It has been calculated that 500 units of coir pith dust would easily absorb 350 units of water and expand to a total of 1,500 units using the first milled coir pith dust.
One tonne of standard size briquettes can be used to produce 1,250 x 4 litre packs of coir pith dust.
The reader's attention is directed to all papers and documents which are filed concurrently with or previous to this specification in connection with this application and which are open to public inspection with this specification, and the contents of all such papers and documents are incorporated herein by reference.
All of the features disclosed in this specification (including any accompanying claims, abstract and drawings), and/or all of the steps of any method or process so disclosed, may be combined in any combination, except combinations where at least some of such features and/or steps are mutually exclusive.
Each feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.
