AI Technical Summary
Technical Problem
Existing automatic feeders struggle to accurately dispense small particle sizes of fish feed, particularly for zebrafish, due to issues like moisture absorption causing feed to stick together and inconsistent feeding schedules, which affects growth and reproductive capacity.
Method used
An automatic feeder with a cylindrical rotor section and stirring mechanism that agitates feed within a hopper, combined with an air supply unit to prevent sticking, and a daisy-chain system for synchronized feeding across multiple tanks.
Benefits of technology
Ensures precise dispensing of small particle sizes, reduces labor burden, and maintains consistent feeding schedules, promoting stable growth and reducing water quality issues in fish breeding.

Abstract
To provide an automatic feeder that can dispense the appropriate amount of even very small particle-sized feed. [Solution] The automatic feeder is installed on top of a fish tank and dispenses a predetermined amount of food into the tank at a set time. The automatic feeder comprises a hopper section 33 for storing food, a cylindrical rotor section 4 rotatably mounted below the hopper section 33 and having a storage recess for receiving a predetermined amount of food from the hopper section 33, and a drive section for rotating the rotor section 4 at a set time. The rotor section 4 is displaced from a reference position where the storage recess faces into the hopper section to a dispensing position where it faces downward, and the food in the storage recess is dispensed into the tank. The hopper section 33 is provided with a stirring section 51 that stirs the food inside the hopper section in conjunction with the rotation of the rotor section 4.
