Fumin a che Fluming water, as referred to earlier, must come from a free or, at least, ap source. It is not viable to use mains water for this purpose, as the volume required for fluming, say 70-80 tons of root vegetables or potatoes per twentyfour hour day, will be of the order of 1.2 million litres. It therefore, desirable that the factory be situated near a river, or waterway, and that the River authority can be persuaded to give the necessary licence to abstract water for this particular purpose. An alternative to this source of supply is, of course, a borehole, or a series of boreholes capable of that sort of capacity. The sugar beet factories use this system of fluming beet into their plants, some thousands of tons per day being moved from silo to process by high pressure water jets, with a minimum amount of manual effort. It is a system well worth emulating in the dehydration factory, where large quantities of roots and potatoes have to be handled End elevation of root vegetable silo with centre fluming channel Silos The construction of the silos is quite a simple matter and a typical size for a 100 ton unit would be 30m by 4m. The side walls are 1m in height and constructed of 23cm thick masonry. Both ends of the silo are left allow incoming bulk loaders or tipper lorries to discharge their loads. The concrete bottom of the silo slopes from either side wall to the fluming channel in the middle. This runs longitudinally down the whole length of the silo with a fall of 50cm in the 30m length. The width of the channel is 30cm, and this is rebated to take 7. 5cm thick timber cover boards which are fitted flush with the sloping silo bottom. The shallowest point of the flume channel must be not less than 15cm deeP, and it is from here that the water supply is introduced from powerful centrifugal Pumps with a capacity of 91,000 to 136,000 litres per hour.
