AI Technical Summary

Technical Problem

Traditional drying boxes have the problem of insufficient drying of the bottom layer of feed in fish feed production, resulting in excessive moisture content, which affects storage quality and safety.

Method used

The drying components include a drying chamber, a fabric hood, a hot air blower, upper and lower drying mesh plates, guide rods, a return spring, a connecting frame, a support plate, and a vibrator. Through the uniform distribution of hot air and the reciprocating oscillation of the mesh plates, the fish feed particles are ensured to be evenly distributed to achieve thorough drying.

Benefits of technology

This method achieves uniform drying of fish feed pellets, improves drying efficiency, ensures that moisture content is within a safe range, and enhances storage quality and safety.

Abstract

This invention provides a high-efficiency drying device for fish feed production, comprising a drying assembly including a drying chamber, a distribution hood, a hot air blower, an upper drying screen, a lower drying screen, eight guide rods, a return spring, connecting rods, a connecting frame, a support plate, and a vibrator. The hot air blower is installed on the lower surface of the drying chamber and communicates with it. By controlling the hot air blower, hot air enters the distribution hood and flows upward through the distribution holes, ensuring even upward flow and uniform contact with the fish feed particles. The vibrator drives the support plate, which in turn drives the guide rods via the connecting frame. The guide rods drive the upper and lower drying screens, which, under the action of the return springs, oscillate back and forth, further distributing the fish feed particles evenly and achieving thorough drying, thus improving the drying effect.
