From Feeding Systems
The model 'HATCHERY' is also for the central timer and distributor box . It is a disc-feeder with a 2,5 l volume feed zylinder that was developed for feeding the finest fry food up to 2 mm pellets. The feeder is suspended above the fry tanks, thus allow you to have sufficient space to work. Power supply is provided via a distributor box equipped with a (220V AC/12 V DC) transformer and a timer. The beginning (i.e. morning) and the end (i.e. evening) of the feeding period are set on the timer. The distributor box automatically issues a pulse which switches the motors of all (up to 24) connected feeders on simultaneously for a short time to move the conveyor disk(s).
The interval between pulses is infinitely adjustable from 0,1 second to 10 hours. For individual feeder dosage, the slot between conveyor disk and the plexiglass zylinder can be adjusted. For this purpose, slacken the adjustment screw (turn counterclockwise), turn the conveyor disk cklockwise (the slot becomes smaller), or turn it counterclockwise (the slot becomes wider), and inaly re-tighten the adjustment screw.
