Automated frozen fish food feeder and automated cleaning system

A system for automated dispensing of fish food into an aquatic holding tank and purging of lines, comprising:

• a reservoir for holding the fish food until a time for feeding is reached;
• a food line connecting the reservoir to the aquatic holding tank;
• a pump system, wherein the pump system is connected between the reservoir and the aquatic holding tank and configured to move the fish food from the reservoir to the aquatic holding tank;
• a cooling system coupled to the reservoir and disposed to cool the fish food;
• and
• a controller module connected to the pump system and to the cooling system, wherein the controller module is programmed to control:
• a temperature of the cooling system that maintains the fish food in a slurry between 1.0° C. and −1.8° C. while in the reservoir,
• operation of the pump system to move fish food from the reservoir to the aquatic holding tank through the food line according to a programmed time schedule and interval of feeding, wherein the operation of the pump system includes a three-cycle feeding process comprising:
• a first cycle where the pump operates in reverse and a first solenoid is controlled to allow fluid to disturb the slurry in the reservoir;
• a second cycle where the pump operates in a forward direction with the first solenoid and a second solenoid controlled to deliver the slurry from the reservoir to the aquatic holding tank;
• and
• a third cycle where the first solenoid and the second solenoid are closed and the pump is operated drawing fluid through the food line, and
• purging food from the food line connected to the reservoir.
