Product Description
The pre-conditioner is mainly composed of blades, augers, and nozzles. Typically, steam, water, or other liquids are sprayed into the pre-conditioner, allowing the materials to mix evenly with additives and soften inside the pre-conditioner. The longer the conditioning time, the better. For general livestock and poultry feed, the conditioning time is around 20 seconds. During thisperiod, powdered feed absorbs the heat and moisture from the steam, making it softer and facilitating pellet formation. For aquatic feed to improve their quality and water resistance, it is generally necessary to extend the conditioning time.

The pre-conditioner ensures the mixing and preconditioning of materials inside the cylinder, effectively improving the pre-gelatinization of the materials. There are two common types of conditioners: single-shaft pre-conditioner and double-shaft type, and sometimes they can be combined for specific needs.
This type of pre-conditioner has a relatively simple structure with a cylindrical shell containing a stirring shaft. The shaft is equipped with multiple adjustable and replaceable paddles.
During operation, the powdered feed particles move in two directions under the agitation of the paddles. First, they rotate around the shaft, and second, they move along the axial direction, following a trajectory similar to a spiral. Typically, a single-shaft paddle conditioner is around 2-3 meters long, allowing the feed particles to stay inside the pre-conditioner for 20-30 seconds, reaching a preconditioning degree of about 20%. This setup can generally meet the preconditioning requirements for some regular pellet feed.
The double-shaft variable-diameter differential-speed paddle pre-conditioner, also known as the DDC pre-conditioner, is developed based on the single-shaft paddle pre-conditioner. Under the action of the paddles, the powdered feed exhibits a partial movement trajectory in the shape of "8", rotating around the shaft and advancing forward. This greatly increases the length of the movement path, allowing for a greater range of adjustable axial movement speed of the feed. A typical conditioner with a length of around 2 meters can control the conditioning time between several tens of seconds and 240 seconds, meeting the requirements for special pellet feeds with high preconditioning and sterilization rates. The preconditioning degree can typically reach 50-60%. Additionally, the paddles with higher relative motion can "cleanse" each other, providing the high self-cleaning ability. This results in an improvement in the feed's residual
phenomenon inside the pre-conditioner.
Features:
Dual Shaft: The pre-conditioner is equipped with two paddle shafts that rotate in opposite directions, ensuring thorough mixing and homogenization of the materials.
Oversized Inspection Port: The pre-conditioner is designed with spacious inspection ports on both sides, which is convenient for cleaning, maintenance and monitoring of the mixing process.
Detachable Paddle Shafts: The paddle shafts in this pre-conditioner can be easily detached for cleaning or maintenance, ensuring convenient and efficient operations.
Motor: The motor used in this pre-conditioner is from Siemens, suitable for various working environments.
Paddles: The pre-conditioner is equipped with two paddle shafts with different rotational speeds and opposite directions,
providing thorough shearing and overlapping mixing of the powdered feed and additives.
Steam Pipeline: The steam pipeline layout is reasonable, ensuring even distribution of steam and materials for mixing. The water
pipeline is equipped with a flow meter to monitor flow rates in real-time.

The two-way and three-way pre-conditioners are used to extend and control the retention time of the powdered feed in the pre-conditioner. They are achieved by stacking 2-3 standard single-shaft paddle pre-conditioners above the extruder. The two-way and three-way multi-layer pre-conditioners are also known as dual-pass and triple-pass type. These pre-conditioners are characterized by being connected in series with multiple steam injection points. During operation, the powdered feed passes through each pre-conditioner in sequence, effectively prolonging the conditioning time and allowing better contact and mixing between the materials and steam. This setup can increase the preconditioning degree of the feed to around 40%.
In order to prolong and control the residence time of the powder in the conditioner, a single-shaft paddle-type conditioner combined with a double-shaft different-diameter and differential-speed paddle-type conditioner are stacked above the extruder.
This kind of conditioner is characterized by being connected in series with multiple steam injection ports. During operation, the powder passes through two conditioners in turn, which prolongs the conditioning time. The material and steam can be more fully contacted and mixed, and the maturity of the powder can be increased to about 50%. Thus this type of pre-conditioner is suitable for large-scale production lines.
(1) Promote Starch gelatinization and protein modification:
Conditioning helps to gelatinize starch and modify proteins in the feed, thereby improving the quality of pellets and the digestibility of the feed.
(2) Increase Extrusion Efficiency: Adding steam softens the materials, making them more plastic and conducive to extrusion molding. This reduces wear on the extruder's components such as the barrel and screw, leading to higher extruder output and lower power consumption.
(3) Eliminate Salmonella in Feed: The combined effect of high temperature during conditioning and the frictional heat and pressure during extrusion can kill Salmonella in the feed, contributing to the health of livestock and poultry.
(4) Increase the Addition Ratio of Liquid Raw Materials (Molasses, Oils): Conditioning allows for higher addition rates of liquid
raw materials in the feed, which can improve the nutritional content and overall palatability of the feed.
