Landuohu Group operational logic: multi‑product manufacturing, hygienic processing, and high‑molasses formulation adaptability.
Customer pain points：Feed product categories are diverse and formula changeovers are frequent. Multi‑batch, differentiated production conditions create a high risk of material carryover and cross‑contamination. At the same time, high‑end poultry and livestock feed formulations often require high‑proportion molasses addition. Molasses has high viscosity, is prone to wall sticking, scorching, and clogging, placing extremely high demands on process temperature control, spraying / coating systems, and piping design.
Landuohu Group requires a processing configuration solution featuring dedicated line segregation, precise temperature control, and anti‑stick / anti‑clogging design, specifically including:
● Dedicated‑line configuration for the pelleting section – separate production by product category to avoid batch‑to‑batch cross‑contamination;
● Scalable multi‑line layout design – supporting simultaneous production of diverse product types and high volumes, enhancing overall production efficiency;
● Customized high‑precision molasses addition system – accurate flow metering to ensure stable and controllable molasses inclusion rates.

Section Description: This section is a necessary process in the production line to ensure feed cleanliness and protect the main equipment in subsequent processes (e.g., crushers and pellet mills).
Cleaning Standards: Impurity removal rate in raw materials ≥99%; magnetic separator field strength ≥4000GS, iron removal rate ≥99%.
Common Equipment: Powder cleaning screen, granular cleaning screen, permanent magnetic drum (iron removal)
Landuohu Group additionally provides： The raw material cleaning section is equipped with an internal circulation specific gravity separation light impurity system, which efficiently separates light impurities while significantly reducing dust emissions, achieving energy conservation and environmental protection.
Section Composition: The grinding section is a critical process in the feed production line. A complete system consisting of an impeller feeder, hammer mill, pulse dust collector, fan, silencer, settling chamber and air‑lock screw conveyor is required to give full play to the working efficiency of the hammer mill.
Process Steps:
1. The impeller feeder feeds materials into the hammer mill and distributes them evenly across each hammer blade. The hammer blades strike the materials uniformly to achieve comminution, which also ensures even wear of the hammer blades.
2. The fan induces airflow to create negative pressure inside the mill chamber for higher grinding efficiency. Dust is collected by the pulse dust collector to prevent dust leakage.
3. The air‑lock screw conveyor transports ground materials to the subsequent process. Equipped with an air lock device, it prevents air cross‑flow.
4. A silencer is installed at the fan outlet to reduce operational noise of the fan.
5. High‑power hammer mills can adopt soft start and automatic load control to enable full‑load operation of the system.
Landuohu Group additionally provides an automatic screen breakage detection function, which enables real‑time monitoring of the mill screen condition. It supports preventive maintenance and helps avoid quality issues caused by screen failures.
Effectively prevents cross‑contamination caused by residual material from different formulations; equipped with a twin‑shaft differential‑speed conditioner to ensure thorough mixing of material and steam, guaranteeing that starch gelatinization consistently meets the required standards; and incorporates a closed‑loop pressure control system that automatically adjusts the extrusion chamber temperature and pressure according to material characteristics, ensuring uniform expansion and consistent pellet shape.
Mixing and customized molasses addition system: To meet the requirements of high‑proportion molasses inclusion, a high‑precision flow‑metering molasses addition system is configured. It features water‑bath temperature maintenance and precise temperature control to enhance fluidity and prevent scorching. A direct‑injection process through the conditioner is adopted, simplifying the process flow and reducing the risk of wall sticking in the piping.
The batching and mixing section system is a critical section of the feed production line. Batching accuracy and mixing homogeneity have a direct impact on feed quality. Engineers at Yuda Machinery adopt optimized process design to strictly guarantee quality requirements. Its features are as follows:
1. Variable‑frequency control is applied to material discharge from all silos to realize fast and slow feeding of the screw conveyors.
2. Calculation of material falling in the air from screw conveyors to weighing hoppers.
3. Airflow relief generated during screw conveying, weighing hopper discharging and mixer discharging processes.
4. Adoption of top‑grade industrial personal computers and advanced batching software.
5. Manufactured from 4 mm carbon steel plate with circular weighing hopper structure and a cone angle ≥ 63°.
6. Metler Toledo load cells; dynamic batching accuracy ≤ 0.3% FS; static batching accuracy ≤ 0.1% FS.
7. Functions:
a. Full‑process computerized batching control;
b. Management functions: store, recall and modify formulas; store, display and print production reports; record raw material consumption, production formula No. and output; cumulative shift, daily and monthly output; cumulative fault records and analytical alert reports.
Special Configuration of Landuohu Group: Automated premix batching. Dedicated premix batching silos are equipped to achieve full automation for addition of core micro‑ingredients and eliminate errors caused by manual feeding.
Mixing & Customized Molasses Dosing System: For high‑rate molasses addition requirements, a high‑precision flow‑metering molasses dosing system is provided. Water‑bath thermal insulation delivers precise temperature control to improve fluidity and prevent coking. The conditioner direct‑injection process simplifies workflows and reduces the risk of material buildup on pipe walls.
Dedicated production lines to prevent cross-contamination: With a large number of production lines and substantial scale, the system is capable of accommodating diverse production requirements and enabling dedicated‑line operation. This eliminates the risk of cross‑contamination during product changeovers, thereby improving product quality and production efficiency.
Pelletizing Section is a key process in the feed production line. The pelletizing system consists of a feeder, conditioner, pellet mill, cooler, fan, cyclone, air lock, crusher (for chick starter feed production), sifter and cooling air duct. Scientific equipment configuration is essential to produce high‑quality pellet feed.
The pellet mill serves as the core equipment of the feed production line. Feed quality depends on the degree of feed gelatinization, which is determined by the conditioning retention time.
Landuohu Group additionally provides： Dedicated production lines for cross‑contamination prevention.
Benefiting from a large‑scale setup with multiple production lines, it adapts to diverse production requirements. Dedicated‑line operation avoids cross‑contamination risks arising from product‑grade changeovers, improving product quality and production efficiency.
High-precision electronic quantitative bagging, combined with automatic sealing and dust control/air recirculation systems, ensures accurate weighing, reliable sealing, a clean working environment, and automatic traceability of production data.
