Benefits of technology
[0050]For example, in wool scouring the water used in the later stages of the cycle may be reused for the initial stages of scouring the next batch of wool. At early stages in the cycle, the high level of contaminants in the wool may mean that high levels of purity of the water used as treatment fluid is not essential. Water from the later stages (in which the wool has been cleaned) may therefore be used without a significant reduction in effectiveness. This may serve to improve cost efficiency—both in terms of reducing total usage and the waste disposal of same, and also associated costs such as heating the treatment fluid.
[0060]The preferred embodiment of conveying in the present invention is composed of a cradle which supports the receptacle and can lift or lower the receptacle relative to the treatment fluid application area.
[0074]In another embodiment the plunger may be in the form of a perforated plate that allows the fluid to pass through the plate surface while preventing the fibres from escaping in the same direction.
Problems solved by technology
Subsequently the complexity and sheer size of the typical plant has advanced such that it has substantial housing, monitoring and maintenance requirements.
Further, the scale of these projects is such that only a few are in a geographical region, leading to additional transportation costs.
In the event of malfunction or an incorrect concentration of cleaning fluid being applied, these systems suffer the downfall of requiring the entire stream of wool to be processed through the line before it can be retrieved and retreated.
Recovering the wool from the line mid-process is a cumbersome procedure and can be very wasteful given the bulk quantities of the wool.
The typical wool scouring plant is too large to rearrange the system—adding or removing stages would require the recommissioning of the plant, an expensive, complex, time consuming and uneconomic act.
Additionally the traceability of individual, small lots of fibres in such a large scale continuous scouring process is difficult, if not impossible.
Merely scaling down the typical wool scouring plant would not address the issues discussed here.
The complexity of machinery in the feeding, distribution, immersion and subsequent dewatering via squeeze rollers of the wool is such that the cost of purchasing and maintaining such equipment (even in miniature form) exceeds the value added when smaller amounts of wool are processed.
In addition miniature equipment would not be suitable, as the wool fibre length remains constant and can wrap around such small scale equipment.
The same difficulties are faced in other situation where a relatively delicate material requires processing in small or discrete quantities.

Embodiment Construction
[0089]With reference to the drawings there is provided in FIG. 1, a fibre processing system generally indicated by arrow (13).
[0090]Fibres (not shown in FIG. 1) are loaded—manually or automatically into a receptacle (1).
[0091]The receptacle (1) is then connected to a conveying system (14) which includes a common lifting cradle (2) configured to raise and lower the receptacle (1) using rams.
[0092]The common lifting cradle (2) then lifts the receptacle (1) above a treatment fluid application area (3).
[0093]An actuator (4) which forms part of the conveying system (14) conveys the receptacle (1) to be positioned above the first of the treatment fluid application areas (3). Alternatively, the receptacle (1) may be manually positioned in the cradle (2) above the treatment fluid application area (3).
[0094]Operation of the cradle (2) is shown in more detail in FIG. 2.
[0095]FIG. 2a shows the receptacle (1) containing fibres (5) positioned above the treatment fluid application area (3).

Abstract
The invention relates to a system and method for processing of fibres and particulates such as wool, wherein material is placed within a receptacle configured to allow the ingress and egress of treatment fluid, conveyed to a treatment fluid application area, treated with a treatment fluid, and conveyed from the treatment fluid application area.
Description
TECHNICAL FIELD[0001]This invention relates to fibre and particulate processing. More specifically, this invention relates to a system for the treatment of fibres including wool and feathers in both their natural and particulate forms.BACKGROUND ART[0002]Wool scouring is the practice of treating raw wool using various solutions in order to remove impurities such as wool grease, suint and dirt. A typical scouring process involves the wool undergoing a series of washes in various cleaning solutions, culminating in the drying of the wool in preparation for further processing.[0003]The design of wool scouring machinery has increasingly focused on the processing of bulk amounts of wool—typically 5,000 kg / hr. Subsequently the complexity and sheer size of the typical plant has advanced such that it has substantial housing, monitoring and maintenance requirements.[0004]This requires a significant investment in capital, land, staff, maintenance and energy.[0005]Further, the scale of these pr...
