Description

Title: A combined cleaning apparatus for cleaning vegetables or other items and an associated method.

Description of Invention

The present invention relates to a combined cleaning apparatus, and more specifically to a combined cleaning apparatus for cleaning vegetables or other items. Embodiments of the present invention include an associated cleaning method.

When vegetables are harvested they are typically contaminated with soil and debris from the environment in which they have been harvested or grown. In addition, the vegetables may include minor surface imperfections or undesired features -for example, fine roots, and the like. This is especially the case for root vegetables which are grown underground and hence may have a comparatively high level of soil contamination.

In order to improve the appearance of the vegetables to potential purchasers and also in order to remove contaminants which may be undesired, a health risk, or may affect the taste of the vegetables, it is known to wash and polish

the vegetables.

Washing machines and polishing machines have been developed for use in the agricultural industry to allow relatively large quantities of vegetables to be processed in a batch or substantially continuous manner.

A conventional vegetable washer consists of a large barrel with an input at one end and an output at the other. The barrel rotates around a central longitudinal axis and is configured to be either partially filled with water, or to have a water spraying arrangement, to aid vegetable cleaning. Vegetables will typically enter the barrel at the input end, pass through the rotating barrel in which the movement of the barrel and the water removes contaminants from the vegetables, and then leave the barrel at the output end.

A conventional vegetable polisher -similarly -consists of a large barrel with an input at one end and an output at the other. The barrel is configured to rotate about its central longitudinal axis. Typically, the barrel carries a plurality of elongate rollers which define a central bore of the barrel. Each roller is covered in bristles. As the barrel rotates, each roller also rotates with respect to the barrel. The vegetables enter the barrel at the input end and contaminants are removed (along with some minor surface imperfections and undesired features) from the vegetables by the action of the bristles of the rollers.

It is not uncommon for vegetables to be processed by a washing machine and then, subsequently, processed by a polishing machine.

Conventionally, each of the washing and polishing machines are separate from one another and conveyor belts, or the like, are used to transport the vegetables from one machine to the next.

Using conveyor belts increases the risk of damage to the vegetables. Damage may occur to the vegetables because they fall from one machine (such as a cleaning machine) to the conveyor belt under gravity. In addition, vegetables may be tall from the conveyor belt itself.

In addition, the use of conveyor belts to transport vegetables between machines increases maintenance costs -as the conveyor belts must be kept in a good condition but are often exposed to abrasive contaminants from the vegetables during use.

Operating space (and, hence, costs) can also be a problem with conventional machines: each machine is large and each conveyer belt transporting vegetables from one machine to another also occupies a large amount of space.

Similar considerations also apply in relation to machines for processing other items -such as waste plastic, cans, and the like.

Embodiments of the present invention, therefore, seek to ameliorate one or

more problems associated with the prior art.

According to an aspect of the present invention we provide a combined cleaning apparatus for cleaning vegetables or other items, the apparatus including: a main frame; a first cleaning part configured to perform a first cleaning operation on one or more items to be cleaned, the first cleaning part being configured for rotation with respect to the main frame and including a first cleaning part barrel body defining a first cleaning part central bore; a second cleaning part configured to perform a second cleaning operation on the or each item subsequent to the first cleaning operation, the second cleaning part being configured for rotation with respect to the main frame, and including a second cleaning part barrel body defining a second cleaning part central bore; and a connecting part coupling the first and second cleaning parts, the connecting part being coupled for rotation about an axis which is substantially parallel to an axis of rotation of the first and/or second cleaning part, wherein the connecting part is configured for rotation with respect to one of the first and second cleaning parts.

The first cleaning operation may be a washing operation and the second cleaning operation may be a polishing and/or drying operation.

Embodiments of the invention are described, by way of example only, with reference to the accompanying drawings, wherein: Figure 1 is a side on view of a combined cleaning apparatus; Figure 2 is a cleaning part configured to perform a polishing operation; Figure 3 is a cleaning part configured to perform a drying operation; Figure 4 is a cleaning part configured to perform polishing and drying operations; Figure 5 is a cross-section view of the combined cleaning apparatus; Figure 6 shows an end view of a combined cleaning apparatus; Figure 7 shows a perspective view of a combined cleaning apparatus; Figure 8 shows a connecting part accord ing to some embodiments; Figure 9 shows another view of the connecting part of figure 8; and Figure 10 shows an end wall used in some embodiments.

With reference to the figures, embodiments of the present invention include a combined cleaning apparatus 10 for cleaning vegetables or other items.

The apparatus 10 includes a first cleaning part 12 and second cleaning part 14. The first cleaning part 12 is configured to carry out a first cleaning operation on one or more items to be cleaned, and the second cleaning part 14 is configured to carry out a second cleaning operation on the one or more items.

For example, the first cleaning operation may be a washing operation, to remove excess soil and debris (or other contaminants) from the one or more items (such as one or more vegetables). The second cleaning operation may be a polishing and/or a drying operation, to polish and/or dry the one or more items (such as one or more vegetables) before they leave the apparatus 10.

The first cleaning part 12 is rotatably mounted on a main frame and has a first cleaning part barrel body 16. The first cleaning part 12 also has a first cleaning part inlet 22, a first cleaning part outlet 26, and a first cleaning part central bore defined by the first cleaning part barrel body 1 6 between the first cleaning part inlet 22 and the first cleaning part outlet 26.

The second cleaning part 14, similarly, is rotatably mounted on a main frame and has a second cleaning part barrel body 18. The second cleaning part 14 also has a second cleaning part inlet 24 and a second cleaning part outlet 28 and a second cleaning part central bore 32 defined by the second cleaning part barrel body 18 (or parts coupled thereto) between the second cleaning part inlet 24 and the second cleaning part outlet 28.

A connecting part 34 is provided to couple the first cleaning part outlet 26 to the second cleaning part inlet 24 such that the first and second cleaning parts 12,14 are in communication with each other. The coupling is such that one or more items which have passed though the first cleaning part barrel body 16 are transported by the connecting part 34 to the second cleaning part barrel body 18.

The connecting part 34 is configured, in some embodiments, to raise one or more items being processed from the first cleaning part 12 to the second cleaning part 14 (i.e. generally in a direction which is against gravity). As such, the one or more items do not fall (under gravity or otherwise) a substantial distance (or any distance in some embodiments) from the first cleaning part 12 to the second cleaning part 14 -which reduces the risk of damage to the one or more items.

The connecting part 34 may include a main body 35. The main body 35 of the connecting part 34 includes a transportation surface 36. The transportation surface 36 includes at least a portion which extends from the first cleaning part 12 towards the second cleaning part 14. The transportation surface 36 may be inclined from the first cleaning part 12 towards the second cleaning part 14.

The transportation surface 36 may include one or more lifting members 42 which are configured to direct the one or more items being processed along and up the transportation surface 36 from the first cleaning part 12 towards the second cleaning part 14.

In embodiments, the transportation surface 36 of the main body 35 of the connecting part 34 is a substantially annular surface. The connecting part 34, therefore, defines a central bore which is in communication at one end with the first cleaning part central bore 30 and at an opposing end with the second cleaning part central bore 32. A diameter of the bore of the connecting part 34 adjacent the first cleaning part 12 may be substantially equal to the diameter of the first cleaning part central bore 30. A diameter of the bore of the connecting part 34 adjacent the second cleaning part 14 may be substantially equal to the diameter of the second cleaning part central bore 32. As such, the bore of connecting part 34 may be generally frusto-conical in shape -with the smaller diameter being towards the second cleaning part 12.

Thus, in operation, one or more items to be cleaned may be delivered to the first cleaning part central bore 30. The one or more items pass through the first cleaning part central bore 30 towards the second cleaning part 14. On reaching the connecting part 34, the one or more items are directed upwardly to the second cleaning part 14 across the transportation surface 36 of the main body 35 of the connecting part 34. The one or more items to be cleaned pass, therefore, into the second cleaning part central bore 32.

In some embodiments, the connecting part 34 is provided in the form generally shown in figures 8 and 9. In such embodiments, the connecting part 34 includes a central bore which is in communication at one end with the first cleaning part central bore 30 and at an opposing end with the second cleaning part central bore 32. The connecting part 34 may carry one or more scoop members 341. The or each scoop member 341 comprises a wall 342 which extends from an inner surface of the connecting part 34 inwardly towards a central longitudinal axis of the connecting part 34. The wall 342 includes a transportation surface 343 which is inclined with respect to the central longitudinal axis of the connecting part 34 and a lateral plane of the connecting part 34.

The wall 342 may be supported by a bracing member 344 which is connected to the wall 342 on a side thereof which opposes the transportation surface 343. The bracing member 344 may comprise a wall which is inclined with respect to the longitudinal axis of the connecting part 34 and which may be approximately perpendicular to the wall 342. In some embodiments, the bracing member 344 comprises such a wall and is generally aligned with the wall 342 of another scoop member 341.

In some embodiments, two scoop members 341 are provided and the two scoop members 341 may include respective walls 342 which together extend across an entire, or substantially an entire, diameter of the central bore of the connecting part 34.

A shaft 3421 may be provided along at least part of the central longitudinal axis of the connecting part 34. The shaft 3421 may be configured for coupling to a feature of the first cleaning part 12 and/or may be configured to be carried by a bearing member (not shown) which is mounted to an end wall 345 (as described below). The bearing member may be moveable, in some embodiments, into a plurality of different locations with respect to the end wall 345 to allow adjustment of the angle of the connecting part 34 with respect to a main frame. In some embodiments, the shaft 3421 is not provided.

An end wall 345 of the connecting part 34 is provided towards the end of the connecting part 34 which is in communication with the second cleaning part central bore 32. The end wall 345 defines an exit aperture 346. The exit aperture 346 provides the communication between the central bore of the connecting part 34 and the second cleaning part central bore 32. The end wall 345 may be configured such that the or each scoop member 341 rotates with respect thereto about the central longitudinal axis of the connecting part 34. In embodiments, the end wall 345 is secured to a main frame (such as the common main frame 20, first or second main frame described below). The end wall 345 may, in such embodiments, not form part of the connecting part 34 but may be part of the second cleaning part 14 or main frame.

In some embodiments, the exit aperture 346 has a width which is substantially equal to a width of the transportation surface 343. A height of the exit aperture 346 may be greater than the width of the exit aperture 346. In some embodiments, the exit aperture 346 is at least partially defined by a shutter member 3461 (see figure 10) of the end wall 345. The shutter member 3461 may be configured to move with respect to the end wall 345 to alter the size of the exit aperture 346. The shutter member 3461 may, therefore, be lockable with respect to the end wall 345 in a plurality of different locations -each different location defining a different size of exit aperture 346. The exit aperture 346 may be rectangular in shape. The end wall 345 may be larger than the central bore of the connecting part 34 at the end thereof which is adjacent the second cleaning part 14 such that, apart from the exit aperture 346, the end wall 345 covers the entire or substantially the entire of that end of the central bore of the connecting part 34.

The end wall 345 may be spaced apart from the connecting part 34 by a clearance distance to allow the unhindered (or substantially unhindered) rotation of the connecting part 34 with respect to the end wall 345. In some embodiments, the level of liquid in the first cleaning part 12 and the relative positioning and/or size of the central bore of the connecting part 34 are such that at least part of the connecting part 34 is immersed in that liquid.

In embodiments, the connecting part 34 is configured for rotation with the first cleaning part 12 such that the or each scoop member 341 rotates with respect to the end wall 345. The or each scoop member 341 is configured to scoop or otherwise collect one or more of the items to be cleaned from the first cleaning part barrel bore 32 and/or a part of the central bore of the connecting part 34 in communication with the first cleaning part barrel bore 32. As the connecting part 34 rotates with respect to the end wall 345, the or each scoop member 341 is lifted to a position in which the one or more items collected by the scoop member 341 are presented to the exit aperture 346 (for example, a lower end of the inclined transportation surface 343 may approach and exit aperture 346). The or each item collected by the scoop member 341 travels down (at least partially under the effect of gravity) at least part of the transportation surface 343 and through the exit aperture 346 to the second cleaning part 14.

In other embodiments, the connecting part 34 is configured for rotation independently of the first cleaning part 12. In some embodiments, the connecting part 34 is configured for rotation with respect to the second cleaning part 14.

In embodiments, the connecting part 34 is configured for rotation with respect to the end wall 345 in a first direction -which may or may not be the same direction as the direction of rotation of either the first or second connecting parts 12,14. In some embodiments, the connecting part 34 is configured for rotation in the first direction such that after collecting one or more items and delivering the one or more items to the exit aperture 346, the connecting part 34 continues rotation in the same direction to collect one or more further items for delivery to the exit aperture 346 and so on. In some embodiments, the connecting part 34 is configured for reciprocal rotational movement with respect to the end wall 345 such that the connecting part 34 moves from a first position to collect one or more items and deliver the one or more items to the exit aperture 346 by rotation of the connecting part 34 in a first direction towards a second position, before rotating in a second opposing rotational direction with respect to the end wall 345 back towards the first position and then rotating in the first direction again (to collect one or more further items, and so on).

Rotation of the connecting part 34 may, therefore, be driven by a drive shaft 161 (as described below) via a belt or may be driven by a different drive shaft which is couple to a different motor (not motor 165). In some embodiments, the connecting part 34 is coupled for rotation with the first and/or second cleaning part 12,14 and is, therefore, attached thereto.

In embodiments including the shutter member 3461, the exit aperture 346 size may be altered to control the rate at which items pass therethrough (for a given rotational speed of the connecting part 34 with respect to the end wall 345).

The end wall 345 may inhibit liquid from the first cleaning part central bore 30 to the second cleaning part central bore 32. Accordingly, the end wall 345 and the position of the exit aperture 346 defined thereby may be such that a liquid level in the first cleaning part 12 and connecting part 34 is below the exit aperture 346.

In embodiments, the wall 342 of each scoop member 341 may define one or more drainage apertures in the transportation surface 343 (through an entire depth of the wall 342) which allow liquid to drain from the one or more items collected by the scoop member 341 as the or each item is lifted towards the exit aperture 346.

In some embodiments, the angle of the or each wall 342 with respect to the central longitudinal axis of the connecting part 34 can be varied. Each scoop member 341 may be associated with a hydraulic or pneumatic actuator to move the or each wall 342 about a hinge to vary the angle of the or each wall 342 in this manner. This variation in angle may be user controlled to control the rate at which items are delivered to the exit aperture 346 from the first cleaning part 12.

In some embodiments, the first and second cleaning parts 12,14 are mounted on a common main frame 20. In some embodiments, the first cleaning part 12 is mounted to a first main frame (not shown) and the second cleaning part 14 is mounted to a second main frame (not shown). The connecting part 34 may be mounted on the common main frame 20, and/or the first cleaning part 12, and/or the second cleaning part 14, and/or a third main frame (not shown).

The first cleaning part 12 and second cleaning part 14 according to some embodiments of the present invention are described in more detail below.

The first cleaning part 12 may be configured to carry out a washing operation on the one or more items to be cleaned. As such, in some embodiments, the first cleaning part barrel body 16 includes a tubular wall which defines a plurality of apertures 60 which extend through an entire depth of the tubular wall. The apertures 60 may be arranged in one or more circumferential bands around the circumference of the tubular wall of the first cleaning part barrel body 16. The first cleaning part barrel body 16 is configured for rotation with respect to the common main frame 20 or first main frame if provided.

The plurality of apertures 60 allow contaminants and debris from the one or more items to be washed out of the first cleaning part central bore 30. In addition, the apertures 60 may provide an abrasive surface which can help in the removal of contaminants and debris from the one or more items.

In some embodiments, the first cleaning part barrel body 16 is at least partially suspended from a drive shaft 161 by one or more belts 162. Rotation of the first cleaning part barrel body 16 may be driven by rotation of the drive shaft 161 via the one or more belts 162. The drive shaft 161 is, in some embodiments, located generally above a central longitudinal axis of the first cleaning part barrel body 16 and may be located generally above the first cleaning part barrel body 16. A longitudinal axis of the drive shaft 161 may be parallel to the central longitudinal axis of the first cleaning part barrel body 16.

The or each belt 162 may pass around a respective part of the first cleaning part barrel body 16. In embodiments, each such part of the first cleaning part barrel body 16 is a substantially uniform surface which may not include any of the plurality of apertures 60 -in order to reduce the wear of the associated belt 162 during use. In embodiments, each such part is at least partially defined by a pair of external radially extending circumferential ribs around an external circumference of the first cleaning part barrel body 16 to inhibit movement of the associated belt 162 out of the part.

The first cleaning part barrel body 16 may, in some embodiments, include an internal spiral rib 44. The internal spiral rib 44 may be configured to direct one or more items to be cleaned from the first cleaning part inlet 22 towards the first cleaning part outlet 26. In some embodiments, the internal spiral rib 44 is integrally formed or is coupled to the or each lifter 42. As such, the or each lifter 42 may comprise an internal spiral rib. In this context, an internal rib is a rib which extends from an inner surface of the relevant part towards the central longitudinal axis of that part. A spiral rib is a rib which is of helical form.

The first cleaning part 12 may include a first tank 31. The first tank 31, if provided, is positioned beneath the first cleaning part barrel body 16 and is configured to hold a volume of liquid (such as water). In embodiments, the first tank 31 is mounted on the common main frame 20 or on the first main frame (if provided).

The first tank 31 may be configured relative to the first cleaning part barrel body 16 such that at least part of the first cleaning part barrel body 16 is within the first tank 31. Accordingly, a liquid in the first tank 31 may also be within at least a part of the first cleaning part barrel bore 30. In other words, the first tank 31 is such that the first cleaning part barrel bore 30 may be at least partially submerged in a liquid in the first tank 31 when in use.

The first tank 31 may be defined by a plurality of walls. One 301 of the plurality of walls is provided towards the first cleaning part outlet 28. The wall 301 may be located such that an upper end of the wall 301 is adjacent the connecting part 34. In some embodiments, the wall 301 is adjacent a part of the connecting part 34 which has a diameter which is less than a diameter of the first cleaning part barrel body 16 adjacent the first cleaning part outlet 28.

In other words, with the apparatus 10 in a normal orientation, the wall 301 may be higher than the tubular wall of the first cleaning part barrel body 16. This may allow the partial submergence of the first cleaning part barrel body 16 in the liquid in the first tank 31. The wall 301 may be one and the same as the end wall 345 and may be located (relative to the connecting part 34) generally as described above in relation to embodiments which include the connecting wall 345.

In embodiments, one or more first cleaning part liquid delivery arrangements (not shown) are provided which are configured to deliver liquid to the first cleaning part barrel body 16 and, specifically, to the first cleaning part central bore 32. The first cleaning part liquid delivery arrangement may include a spray arrangement which is located at least partially within the first cleaning part central bore 32 and which is configured to spray a liquid within the central bore 32. The first tank 31 may, therefore, collect liquid which is delivered to the first cleaning part central bore 32 by the one or more first cleaning part liquid delivery arrangements and which passes through the plurality of apertures 60.

The first tank 31 may include a drain 313 which is located to allow the circulation of fluid from the tank 31 to the or each liquid delivery arrangement (if provided).

In some embodiments, the connecting part 34 is provided with a liquid delivery arrangement (the connecting part liquid delivery arrangement'). The connecting part liquid delivery arrangement is configured to deliver liquid to one or more items on the connecting part 34. For example, the connecting part liquid delivery arrangement may be configured to deliver liquid to one or more items which pass from the first cleaning part 12 to the second cleaning part 14. In some embodiments, the connecting part liquid delivery arrangement is configured to deliver liquid to one or more items as they are carried or lifted by the connecting part 34 out of the volume of liquid held in the first tank 31. The connecting part liquid delivery arrangement may, therefore, be configured to supply clean' liquid which has not been recycled (i.e. circulated) from the first tank 31 to the connecting part cleaning arrangement.

The clean' liquid may be water from a mains or tank supply. The connecting part cleaning arrangement may, therefore, be configured to supply a liquid to rinse the one or more items as they pass from the first to the second cleaning parts 12,14.

The connecting part liquid delivery arrangement may comprise a pipe which ends through the first and/or second cleaning part 12,14 such that a portion of the pipe is located adjacent the connecting part 34. That portion includes one or more apertures to allow liquid carried by the pipe to be sprayed onto the one or more items.

In embodiments in which the connecting part 34 includes a wall which is at an angle with respect to a longitudinal axis of the first and/or second cleaning parts 12,14, the connecting part liquid delivery arrangement comprising a pipe may be angled in a corresponding (e.g. parallel) manner. The pipe in some embodiments is an example of a liquid carrying conduit and other liquid carrying conduits could equally be used.

In some embodiments, the first tank 31 includes an auger 311 which is located towards the bottom of the first tank 31 and which is configured to drive the movement of contaminants and other debris (such as removed surface imperfections) which have been removed from the one or more items to be cleaned. Such contaminants and other debris may have been washed from the one or more items, passed through one or more of the apertures 60 and fallen through the liquid in the first tank 31 towards the bottom of that tank 31.

The auger 311 may be configured to drive movement of the contaminants and other debris to a collection aperture 312 -from which the contaminants and other debris may be collected (e.g. by the connection of a collection vessel to the collection aperture 312). A conveyor belt 314 may be provided to deliver the contaminants and other debris from the collection aperture 312 to the collection vessel.

In embodiments, the drain 313 (if provided) is located above the auger 311 (if provided).

In embodiments which include the auger 311, the auger 311 has a longitudinal axis which extends along a lower surface of the first tank 31. This longitudinal axis may be a substantially horizontal axis.

Rotational movement of the auger 311 is driven by a motor and the motor may be located at either end of the auger 311.

In some embodiments, the second cleaning part 14 is configured to carry out a polishing operation and/or a drying operation.

The second cleaning part barrel body 18 carries a plurality of rollers 64 which define the second cleaning part central bore 32. Each roller 64 is configured for rotation with respect to the second cleaning part barrel body 18 and the second cleaning part barrel body 18 is configured for rotation with respect to the main frame (such as the common main frame 20) to which it is mounted.
