Identity

The Automatic Pan Feeder is an automated feeding system utilizing closed mechanical feed distribution. It operates via an auger-driven pan mechanism to reliably deliver dry mash, crumbles, or pellets to poultry flocks.

Overview

The Automatic Pan Feeder is a high-priority, automated feeding setup designed to maximize feed conversion ratio (FCR) in high-density operations. It utilizes an electric motor and a coreless steel helical auger inside galvanized steel pipes to move feed from a bulk hopper. Operational failures can include motor failure, capacitive sensor failure due to dust, mechanical bridging blocking the auger inlet, and feed contamination if drop-tubes are adjusted incorrectly.

Structured Facts

Classification

Closed Mechanical Feed Distribution Equipment / Automated.

Purpose

Maximizes feed conversion ratio (FCR), ensures uniform feed distribution, and minimizes feed wastage.

Working Principle

Operates using a coreless steel helical auger inside galvanized steel pipes, driven by an electric motor to move feed from a bulk hopper. Feed drops through openings along the pipe to fill individual suspended pans. A control pan at the end of the line has a capacitive proximity sensor. When empty, the sensor detects absence of feed and signals the Smart Controller to start the motor, which runs until the control pan is replenished and the sensor circuit opens.

Technical Specifications

• Feed Conduit Pipe Diameter: 45 to 60 mm (Equipment Specs).
• Standard Pan Outer Diameter: 330 to 360 mm (Design Specs).
• Auger Rotation Speed: 80 to 120 RPM (Motor Gear Specs).
• Capacitive Sensor Voltage: 24 VDC or 230 VAC (Sensor Datasheets).

Capacity

• Feed Distribution Density: 45 to 60 broilers per pan (Standard Broiler Manuals).

Installation Requirements

Feeder pans are suspended below drop-tube openings along the pipe. The feeder line must be raised continuously using a centralized winch to keep the outer rim of the pans level with the birds' crop height as they grow. The adjustable drop-tube sleeve must be calibrated to regulate feed depth based on flock age.

Operating Parameters

• Drive Motor Rating: 0.37 to 0.75 kW (IP55 Dust-Protected).

Maintenance

Before sanitizing the house between flocks, the line should be run dry to clear out remaining feed.

Cleaning & Disinfection

Line run dry before house sanitation.

Advantages

Ensures uniform feed distribution, minimizes feed waste, maximizes FCR, automates feeding schedules via Smart Controller integration.

Limitations

Mechanical bridging of feed in the hopper boot can block the auger inlet, causing the motor to run dry and overheat. Capacitive proximity sensors can drift or fail if coated in fine dust, leading to continuous running (overflow/waste) or failure to start (starvation). If line height is set incorrectly, young birds may climb inside pans, contaminating feed.
