The Blitz feed cannon has been in production since 1994 and is in its third edition, with each new model an improvement on the last.
The current model benefits from tens of thousands of hours of working experience gained by our customers and millions of tons of feed spread across pens over the years. This experience has contributed to the steady development of a tough reliable feed cannon.
The standard Blitz feeder has a one-piece aluminium chassis and hopper, but is available at special request in stainless steel, for marine farms where high ambient temperatures are experienced and corrosion even more severe. Feeders can be supplied with a water pump powered by a 5.5 hp Honda petrol (gasoline) engine, a 6 hp Lombardini diesel engine, or with a hydraulic drive, powered from a work boat’s own hydraulics. The heart of the machine is a very simple yet effective venturi, where water is forced at high pressure through a shaped nozzle. The food flows from the 50 kg hopper, metered by a slide valve into the high velocity water jet and is propelled through the flexible barrel into the fish cage. The flexibility of the barrel enables a wide spread of food across the entire surface of the cage by simply aiming it to where you want the food to go. Blitz feeders are compact and light in weight, so they occupy very little space in a work boat, adding less than 50kg to the payload. This also makes them easy to move around between boats or onto the shore.
Working with a Blitz feeder couldn’t be easier. The 50kg hopper height is low, at just 75c/m, so filling is easy. The metering valve, the only moving part on the feeder, is smooth in action and feeds the pellets into the water flow evenly. The feeding rate depends somewhat on the size of the feed pellets and how well they flow, averaging normally around 40kg/min. The rate is of course variable down to zero, by adjusting the size of the opening of the metering valve. The feeding range is between 18 and 22 metres. Approximately three-quarters of a 70m circular cage surface can be reached. In our experience, a gasoline engine will normally run for approximately 1-1½ hours between re-fills. Diesels run for longer.
