Detailed Description
Potato crisps are manufactured by first selecting potatoes with a solids content of from 20% to 25%. The potatoes are preferably of the variety Lady Rosetta which generally have a solids content of 20% to 22% good colour, size, shape and good quality skin. They are generally used directly after harvesting. Late potatoes of :. the variety Lady Clare are stored in a controlled storage environment. The variety Saturna may also be stored in the same way for future processing. In the case of S...
stored potatoes the storage temperature is from 7 to 8°c to minimise sugar development To prepare the stored potatoes for processing they are first tempered to raise the temperature to between 15 and 20°C over a 24 hour period. *5SS
:; The solids content of the input potatoes is checked and potatoes which have a * 30 solids content of preferably 21 to 22% are selected for further processing. This range of solids content enables oil absorption and required moisture content in the finished crisps.
The potatoes are also selected based on size. We have found that for optimum processing efficiency there should be at least 75 and at most 110 single potatoes per 10 Kgs of input potatoes. The potatoes are graded and those in the size range 40mm to 85mm are selected.
Selected potatoes are loaded into a storage hopper. Potatoes to be processed are first passed through a cyclone, any heavy waste such as stones drop to the base of the cyclone and are discharged to waste. The potatoes are then delivered into a washer reel in which the potatoes are turned in a bath of water to wash soil from the surface of the potatoes. The washed potatoes are then delivered into a floatation tank in which any light waste such as straw floats to the surface and is removed for discharge to waste.
The washed potatoes are then delivered into one of a number of batch peeling units each of which has peelers/cutters having cutting surfaces with a coating of carborundum. The coating on the cutters wears off over a period of time and we have found that for optimum processing efficiency the peeler to which the potatoes are directed is selected based on downstream processing considerations to maxirnise throughput. In the case of a peeler with freshly coated cutting blades the residence time required to peel the potatoes can be as low as 5 seconds but can be up to 100 seconds if the peeler requires freshly coated cutting blades. A balance is achieved between achieving optimum peeling efficiency without surface blemishes and throughput requirements. *... * * *S..
The peeled potatoes are then passed over a sizing mesh. Potatoes below a size of about 75mm pass through the mesh and larger ones which do not pass through the mesh are directed to a halving device which cuts the large potatoes in half across the widest axis as orientated by a set of oblong rollers. The halved potatoes ::::; are returned to the main processing stream of potatoes. * 30
The potatoes are then sliced. The slice thickness is adjusted based on the solid content of the potatoes in the table below to ensure the process is controlled as uniformly as possible.
% Solids or Dry Matter Slice thickness in thousandths of an inch 20.1-21.1 54-58 21.2-21.9 54-58 220-229 52-56 23.0-237 50-54 23.8-248 50-54 24.9-25.0 48 -52 The slicer blades on each of the slicer heads are changed every 2 hours to ensure consistent slice thickness.
The potato slices are rinsed in cold water (less than 25°c) to remove all cold water soluble starches which have an adverse impact on browning during coking. The removed starch can be recovered by centrifuging the waste water. The washed potato slices are then shaken using vibration to remove excess water. As determined by a fry test and colour measurement (Hunter Laboratory Instrument specification >55) on incoming potatoes the potato slices may then pass through a blanching process at a temperature of 60°C -80°C or may bypass this process entirely. The blanched potatoes are then dried in an air blower which removes surface water which would have an adverse impact on frying. The dried potato slices are then delivered onto an accelerator conveyor which accelerates the potato slices and delivers them into a continuous in-line bath of cooking oil. The *...
oil is 100% sunflower oil.
****..
In the oil the potato slices pass through three stages. In the first stage, the oil is at * a temperature of 172°C to 179°C preferably below 174°C and the slices have a *::::* residence time of from 25 to 35 seconds, ideally about 30 seconds. In the second *:*. stage the oil is also at a temperature of 172°C to 176°C, preferably below 174°C and the residence time is about 50 to 70 seconds, ideally about 60 seconds. In the third stage the oil is at a temperature of from 160°C to 164°C, preferably below 162°C and the residence time is from 50 to 70 seconds, ideally about 60 seconds.
We have found that the processing in these three stages optimises the manufacture of good quality crisps. The first stage facilitates water removal. The second stage aids colour formation whilst the third stage ensures that the crisps are fully cooked without burning During passage through the bath of hot oil, steam generated is removed and may be used as an input for a heat recovery system.
The quality of the cooked potato slices is then checked in-line. Any slices which are outside a defined specification and rejected prior to packaging.
Referring to Figs. I and 2, a crisp oil cooking bath I with a steam take-off hood 2 is illustrated On discharge from the cooker, the crisps pass along a conveyor 3 and a guide arm 4 directs the crisps under an infra red detector 5. The JR detector is used to measure the moisture content and the fat content of the crisps in-line. If the moisture content is above 2% and/or the fat content is greater than a target which may, for example be 35%, the crisps are rejected as will be described in more detail below. The crisps all pass through a colour detector 10 in which the colour of the crisps is detected in-line to identify any crisps which have excessive browning/burning. An air blower is activated to blow any such crisps into a waste collecting chute 13, Onto a conveyor 14 and into a waste collection bin 15. Crisps which meet the colour specification travel down a conveyor 20 leading to buckets 21 ofa bucket elevator 22. * . **.
The bucket elevator 22 delivers the crisps into an overhead chute 25. As will be particularly apparent from Figs. I and 3 the chute 25 has a gate 26 covering an opening 30 into a reject chute 31 leading to a waste bin 32. The gate 26 is perforated so that even when closed any small crisp pieces will fall through it and be discharged to waste 31, 32. The gate 26 is pivotally mounted and is activated * 30 in response to a fault condition such as the fat and/or moisture content of the crisps. If the fat and/or moisture content is not within specification as measured in-line (described above) the gate 26 is opened and the crisps and discharged to waste 31, 32.
There are significant improvements in crisp quality and increased throughput and yield as a result of the optimisation of the process. Crisps which do not meet the desired specification are rejected efficiently at an early stage of the process, before flavouring and packaging.
Crisps which pass over the gate 26 are directed by a directing device 40 either into a holding area 41 or into a delivery chute 42 for feeding to a plurality of multihead weighers 45. The holding area 41 is used to smooth out any variations in crisp production throughput and packaging throughput. If the packaging throughput is reduced the crisps may be directed along a feed conveyor 43 into the holding area 41 which may have a significant capacity, for example, equivalent to 20 minutes production. On demand, crisps from the holding area 41 are directed along an outfeed conveyor 44 into the packaging feed chute 42.
Referring to Fig. 4, crisps may be directed to any one of a plurality of flavouring station 50 which apply a flavouring and direct the crisps to an associated multi head weigher 51 which weigh Out and deliver a required quantity of crisps into an associated vertical form fill and seal machine 52 which forms individual primary bags containing, for example 30g of crisps. The seal of the bag is then tested using a seal tester 53 and the weight is checked using a check weigher 54. As will be described in more detail below, the individual bags are collated in a collator :. 55, picked up 56 and placed into a magazine 57 prior to loading into a case/box 58 which is then sealed 59. The sealed cases are then delivered along an output *S..
conveyor 60 for palletisation. * *
In more detail, and referring particularly to Figs. 5 to 9 a plurality of single packs are delivered along conveyors 71 in two lanes 72 to a packaging station 75.
The packs 70 are arranged substantially horizontally and a suction lifter 76 * 30 travelling on a track 77 is used to lift up the packs 70 and deliver them into a magazine 78. A case/box 80 is aligned with the magazine 78 with the top opening of the box arranged vertically and a pusher 81 is used to deliver the two rows of packs into the box. The box 80 is then turned through 90° to upright the box so -12 -that the top opening is uppermost. The box is then sealed by a box sealing unit 83.
This arrangement greatly increases packing speed. In addition, because in storage, transit, and at the point of sale the bags are in a vertical orientation a number of benefits accrue. As there are two rows packed vertically, the bag seals are maintained. Further, the bags can be more easily mechanised as groups of bags may be easily lifted out and placed in a merchandising unit without having the turn or re-arrange the bags.
Referring in particular to Figs. 10 to 12 individual packs 70 of snack food products such as crisps may alternatively be packaged into multipack bags containing, for example, six individual bags. The primary bags 70 are delivered to one of a plurality of multihead weighers 90. A plurality of filled primary bags from the multihead weigher are then packed in an associated vertical form fill and seal unit 91 to form a multipack bag 93 containing the primary bags 70. The multipack bags 93 are check weighed 94, then collated in a collator 95 and then loaded into a case 96. The cases 96 containing the multipack bags 93 from the collating/packing stations are then delivered onto a conveyor 97 to a single automatic case sealer 98. A code on the case 96 is read and the case sealer 98 automatically adjusts to suit the case type and apply a seal and deliver the sealed case along a cut feed conveyor 99 for palletisation. * *
This arrangement greatly increases packing efficiency, speed and toughout with low labour costs.
