What does the 1-3t/h chicken feed production line include

The 1-3t/h chicken feed production line automates feed transformation, enhancing nutritional value and production efficiency through stages like crushing, mixing, pelletizing, cooling, and packaging.
It utilizes hammer or roller mills for size reduction, vertical mixers for uniform blending, pellet mills with adjustable dies for shaping, and air-flow coolers for rapid pellet cooling, culminating in precise, contaminant-free packaging.

The 1-3t/h chicken feed production line is an indispensable piece of equipment in the modern poultry farming industry. It efficiently transforms raw materials into high-quality pellet feed through an automated process, significantly enhancing the nutritional value and efficiency of feed production.

Crushing Stage

The crushing stage is the initial step in the 1-3t/h chicken feed production line. Its purpose is to preliminarily process large-particle raw materials such as corn and soybean meal to facilitate subsequent mixing and pelletizing. Hammer mills or roller mills are typically used for this purpose. Hammer mills employ high-speed rotating hammers to impact and tear the raw materials, while roller mills use two counter-rotating rollers to crush and grind the materials.

Hammer Mill

The structure of a hammer mill includes a rotor, hammers, a screen, and a feeding device. The rotor’s speed determines the crushing efficiency, and the shape and arrangement of the hammers affect the uniformity of the crushed particle size. The screen controls the size of the crushed material and can be replaced with screens of different apertures as needed. The feeding device is designed to ensure a uniform entry of raw materials, preventing overload or underload operation of the mill.

Roller Mill

Roller mills consist of two or more counter-rotating rollers, which can be smooth or toothed to meet different crushing requirements. The advantage of roller mills is that they cause less damage to the raw materials, preserving their nutritional structure, making them suitable for temperature-sensitive materials.

Mixing Stage

The mixing stage is crucial for ensuring a balanced nutritional composition of the feed. The design of the mixer must ensure that various raw materials are thoroughly mixed in a short time to form a homogeneous mixture. Common types of mixers on the market include vertical and horizontal mixers.

Vertical Mixer Vertical mixers have a relatively simple structure, typically consisting of a vertical cylinder and a driving device at the bottom. Raw materials are added from the top and mixed by internal stirring blades that flip and tumble the materials. The advantage of a vertical mixer is its compact structure and small footprint, but its mixing efficiency is relatively low.

Pelletizing Stage

The pelletizing stage is the core of the 1-3t/h chicken feed production line. Its purpose is to press the uniformly mixed raw materials into pellet form to facilitate feeding and digestion by chickens. Pellet mills usually consist of a screw, a die, a cutting device, and a transmission system.

Screw

The screw is the power source of the pellet mill, propelling the raw materials forward through its rotation. The design of the screw, including pitch, groove depth, and thread shape, directly affects the production capacity and pellet quality of the pellet mill.

Die

The die is a key component of the pellet mill, with its hole size and shape determining the size and appearance of the pellets. The material of the die is usually alloy steel, which has high strength and wear resistance. To accommodate different raw materials and pellet requirements, dies can be designed with various hole shapes, such as circular, square, and annular.

Cutting Device

The cutting device’s function is to cut long pellets into short ones of the desired length. It cuts the long pellets extruded from the die. The device typically consists of a set of rotating blades. The spacing between these blades can be adjusted. This allows for control over the length of the cut pellets.

Cooling Stage

The cooling stage is an important step in ensuring the quality of pellet feed. Newly made hot pellets need to be cooled down quickly to reduce nutritional loss and improve the hardness and durability of the pellets. Cooling systems usually use air-flow or drum-type coolers.

Air-Flow Cooler An air-flow cooler cools the pellets with high-speed air. The pellets are suspended in the air by the airflow, fully exchanging heat with the air to achieve rapid cooling. The advantage of an air-flow cooler is its fast cooling speed and even cooling, but it has a higher energy consumption.

Packaging Stage

The packaging stage is the final phase of the 1-3t/h chicken feed production line. Its purpose is to weigh and package the cooled pellet feed for easy storage and transportation. Packaging machines usually employ an automatic weighing system and an automatic sealing device.

Automatic Weighing System

The automatic weighing system achieves precise weighing of pellet feed through sensors and control devices. The weighing system can automatically adjust the weighing range and accuracy according to different packaging specifications.

Automatic Sealing Device

The automatic sealing device’s role is to seal the packaging bags to ensure that the pellet feed is not contaminated during storage and transportation. The sealing device usually uses thermal or ultrasonic sealing technology, characterized by a strong seal and good sealing quality.
