Tong pre-soak tanks, also known as wet hoppers, ensure an exceptionally gentle reception of crop at high throughputs. Suitable for the infeed of dirty or clean vegetables including carrots, potatoes, parsnips, swedes and more, Tong pre-soak tanks are a popular choice at the infeed of carrot washing lines to effectively cool and loosen soil from crop post-harvest, prior to the carrot washing and polishing process.
Tong wet hoppers receive crop carefully and transfer it onto an outfeed web elevator where crop is drained as it exits the hopper. Pre-soak tanks are often integrated in packhouse environments as the presence of water means that excess debris, soil and sand separates from the crop within the hopper. This gives the crop a light soaking action, which can be enhanced when crop is left to ‘soak’ in the tank for longer dwelling times.
All debris from the crop is then easily removed from the tank via the pre-soak tank’s dump valves. Tong pre-soak tanks are also available with the option of an integrated tank auger for even more effective accumulation and removal of soil and debris.
