Title: Drying Apparatus Description of Invention
This invention relates to a drying apparatus and particularly, but not exclusively, to a drying apparatus for drying vegetables after they have been washed prior to them being packed, for example, for sale in a retail outlet.
Hitherto such a drying apparatus has comprised a series of water-
absorbent rollers which support an article to be dried and which are opposed to lower rollers that squeeze water out of the water-absorbent rollers which has been transferred thereto from the article to be dried.
This type of apparatus has suffered from the disadvantage that these are many moving parts which are constantly running in water and therefore the known apparatus requires considerable maintenance and so is costly to operate.
An object of the present invention is to provide a drying apparatus whereby the above mentioned disadvantage(s) is/are overcome or reduced.
According to the present invention we provide a drying apparatus comprising first and second elongate endless rotatable loops having opposed operative surfaces therebetween for engagement with an article to be dried in a work zone defined between said operative surfaces, at least one of said operative surfaces being water-absorbent and there being a squeezing means to engage said at least one operative surface to remove water therefrom.
Both said operative surfaces may be water-absorbent.
The or each operative surface may comprise a water-absorbent material disposed on a carrier.
The water-absorbent material may have a plurality of water-absorbent cells. The water-absorbent material may comprise felt or a natural or a synthetic sponge such as neoprene.
( Each endless loop may be entrained around first and second spaced guide means.
Each guide means may comprise a roller.
Each roller may have a cylindrical loop engaging surface.
At least one of the first guide means may be driven by a drive means which may comprise a motor.
The second guide means may be driven by a drive loop, such as a chain, from the first guide means.
The first and second guide means may be disposed so that a horizontal plane lies in a part of the surface of each guide means.
A squeezing means may be adapted to engage the water-absorbent surface of the or each loop at a desired position.
Said desired position may be disposed on the opposite side of the second guide means to the first guide means.
The squeezing means may comprise a roller, the surface of which is impermeable to water, and which engages an operative surface of the loop so as to squeeze said loop whereby water is removed therefrom.
Preferably drive transmission means are provided to drive the first guide means by the drive means.
The opposed operative surfaces in said work zone may be driven so as to move in the same direction.
Alternatively the opposed operative surfaces in said work zone may be driven so as to move in opposite directions.
The operative surfaces in said work zone may be driven to move at the same speed or at different speeds.
An article may be conveyed through said work zone by at least one of said endless loops.
An embodiment of the invention will now be described in more detail by way of an example with reference to the accompanying drawings wherein:
i Figure 1 is a plan view of a drying apparatus embodying the invention, Figure 2 is a side elevation of the drying apparatus of Figure 1, Figure 3 is an end view of the drying apparatus of Figure 1 with the components in an operative position, Figure 4 is an end view of the apparatus of Figure 3 but showing the components in an inoperative position for cleaning, and Figure 5 is a fragmentary cross section taken through a longitudinally extending member of a loop carrier.
Referring now to Figures I - 3, a drying apparatus is indicated generally at I O and comprises a base frame 11 which may be of any desired construction but which in the present example comprises four upright legs 12 arranged in a first pair 12_ on one side of the apparatus and a second pair 12_ on the other side of the apparatus.
Pivotally connected to the uprights 12_ by pins 15 are upper and lower pairs of trunnions 6, 17 respectively. The trunnions 16, 17 are connected to longitudinally extending members 18, 19 respectively of upper and lower endless loop carriers 20, 21. The members 18, 19 are of generally channel section having opposed limbs 22 with an interned flange 23 at each end thereof.
The trunnions 16 are fastened to the flanges 23.
Telescopically mounted within the channel and retained therein by the flanges 23 are end members 24 also of channel configuration having inturned flanges 25 and which carry bearings for first and second rollers 26, 27 respectively. Adjustments means 28 are provided whereby the end parts 24 may be adjusted longitudinally along the part 18. The adjustment means 28 comprise a bar 29 welded in the interior of the channel section member 18 and provided with a screw threaded part 30 which is in screw threaded engagement with a screw threaded elongate member 31 having a head 32, for engagement by a suitable tool such as a spanner, and having an end part in longitudinally fixed
( but rotatable engagement with the end part 24 whereby the distance between the rollers 26 and 27 may be adjusted.
Entrained around the rollers 26 and 27 is an endless loop 35. The endless loop has on its outer surface a sponge-like layer 36 which provides an operative surface which may be made of any suitable material such as felt or neoprene foam so long as it is water-absorbent and sufficiently mechanically robust. The end part 24 adjacent to the roller 27 is provided with a further roller 38 which is water impermeable' such as a steel roller having a cylindrical steel operative surface, and is mounted so as to squeeze the water permeable layer 36 on the belt 35 so as to squeeze water therefrom. The roller 38 is provided with a gear 39 which is in mesh with a gear 40 fixed to rotate with the roller 27 so that the roller 38 is caused to rotate with the roller 27.
The roller 26 at the opposite end of the drying apparatus to the gears 39 and 40 is provided with an electric motor 45 fixed to a gearbox 46 which provides a drive transmission input to the roller 26. The roller 26 and the roller 27 are each provided with a sprocket which is engaged by a chain, not shown, so that the roller 27 is driven from the roller 26. Alternatively, the roller 26 may be driven by a shaft mounted electric motor.
Members similar to the members 18 and 24, indicated in Figure I by the reference numerals 18_ and 24a, are provided with bearing means to support the adjacent ends of shafts which carry the rollers 26, 27 and 38. The members 18, 18_ and 24, 24a are joined together by the transverse members not shown.
Beneath the loop 35 is provided a similar set of components for a lower loop which are the same as the components described herein before and these components are indicated by the same reference numerals but with addition of a prime sign. All besides the drive motor 45 and transmission 46, are arranged in an orientation which is at 180 to that of the loop 35 so that the roller 27' and the roller 38' are shown at the right-hand side of Figure 2 whilst the roller 26'
( is shown at the left-hand side of Figure 2. The roller 26' is driven by a motor 45' through a drive transmission 46' in a similar manner to the roller 26. As can be seen from the drawings the motor and transm ission 45, 46 is on the same side of the belts as the motor and transmission 45', 46' but at the opposite end of the apparatus. Sprockets and a chain, not shown, are provided to drive the rollers 27' and 38' from the roller 26'.
On the side of the apparatus having the uprights 12_ the elongated component 18 of the lower loop 35' is supported on the top of appropriately dimensioned uprights 12b whilst the lower component 18 has an additional flanged component 51 which supports lower part of a component 18 of the upper loop 35.
In normal operation as shown in Figures 1 - 3 the region between the operative surfaces of the upper and lower endless loops 35, 35' provides a work zone 52 where the operative surfaces 36, 36' are opposed.
When it is desired to remove detritus or wherein the other obstructive material from the upper and lower runs and the components thereof they can be pivoted to an inoperative position such as that shown in Figure 4 on the pivot pins 15. This may be done manually or mechanically using suitable pneumatic or hydraulic rams or the like and in addition any suitable means for holding the components in a desired position may be provided.
In use, articles to be dried, for example potatoes, are fed into the work zone 52 at the left-hand end thereof as shown in Figures I and 2 and are caused to pass through the work zone 52 by virtue of being engaged between the operative surfaces provided by the endless loops 35 and 35' and water which has been used to wash the potatoes is absorbed by the water-absorbent layer on the loops. The dried potatoes are fed from the lower endless loop 35' at the right-hand end thereof onto a suitable conveyor and liquid which has been absorbed in the lower loop absorbent material is squeezed therefrom by the roller 38' and falls into a suitable disposal arrangement 53. Liquid from the
( upper loop is squeezed therefrom by the roller 38 and after falling downwardly onto wet potatoes yet to be dried is received in a suitable disposal arrangement 54. Although in a present example the upper loop 35 is intended to be driven in an anti-clockwise direction so that the lower run thereof moves from left to right in Figure 2 and the lower loop 35' is intended to be rotated in a clockwise direction so that the upper run thereof moves from left to right, if desired the directions of rotation of the belts may be such that the opposed operative surfaces move in opposite directions but to ensure that the articles pass along the work zone the speeds of rotation may be appropriately adjusted so that there is a net movement of articles to the right. Alternatively such a differential rate between the operative surfaces of the work zone may also be provided when the belts are rotating so that the opposed operative surfaces are moving in the same direction. Wet products are fed into the work zone 52 by means of a conveyor or similar means and dried products at the opposite out-feed end of the zone 52 are picked up by a cross-belt conveyor or an in-line belt conveyor.
In the present specification "comprises" means "includes or consists of"
and "comprising" means "including or consisting of''.
