For large-scale chicken farms and livestock manure fertilizer factories, should they choose organic

In the livestock and poultry manure fertilizer plants that are part of large-scale chicken farms, the selection of packaging machines should be based on a comprehensive assessment of production scale, material characteristics, automation requirements, and long-term operating costs. The following is the targeted analysis:

I. Core Comparison: Bucket-less vs. Bucket-with Packaging Machine

Comparison items | Bucket-less packaging machine | Bucket-with packaging machine

Applicable materials | Powder/granular fertilizers with good fluidity (dry, no caking) | Organic fertilizers with high viscosity, easy caking or high moisture content

Accuracy | Medium (±0.5% to 1%) | High (±0.2% to 0.5%, multiple calibrations available)

Speed | Fast (Continuous filling, suitable for large quantities) | Slow (Requires waiting for the hopper to weigh)

Residue and contamination | Very little, suitable for high hygiene standards | The hopper is prone to residue and needs to be cleaned regularly

Maintenance cost | Low (simple structure) | High (Many mechanical parts, requiring anti-corrosion treatment)

Price | Lower | Higher (Complex structure + anti-corrosion design)

Ii. Selection Suggestions for Large-scale Fertilizer Plants

Give priority to the situation where the bucket packaging machine is selected

The material characteristics are complex: Chicken manure fertilizer usually has a high moisture content (it may still contain 15% to 30% water after fermentation), a lot of fibers, and is prone to caking or sticking together. The gravity weighing method with a bucket elevator can better address the issue of poor fluidity. Combined with an arch-breaking device (such as a vibrating motor or pneumatic slapping), it can ensure stable material discharge.

High-precision requirements: Large factories often need to meet commercial sales standards (such as 25kg per bag with an error of ≤0.1kg), and hopper machines are more likely to meet the standards after multiple weighing calibrations.

2. The situation of a bucket-less packaging machine can be considered

The fertilizer after secondary processing: If the manure and sewage have undergone deep drying and granulation (particle diameter 1-4mm and moisture content < 10%), the efficiency of the hopper screw filling machine is higher (such as 800-1000 bags per hour).

Control the initial investment: The price of a bucket-less machine is approximately 60% to 70% of that of a bucket-equipped one. It is suitable for transitional use when the budget is tight, but it needs to be combined with pre-treatment (such as screening and impurity removal).

Iii. Key Precautions

1. Anti-corrosion design: Chicken manure is highly corrosive. The equipment should be made of 304 stainless steel or carbon steel with anti-corrosion coating (such as polyurethane), and special attention should be paid to the contact parts such as the hopper and spiral blades.

2. Capacity matching: If the daily output of a single production line is less than 50 tons, 1 to 2 bucket conveyors (such as DC-50 type, 50kg per bag) can be selected.

Daily output > 100 tons: It is recommended to combine a bucket machine with a bucket machine without a bucket, and process different materials on separate lines (for example, use a bucket machine for powder fertilizer and a bucket machine for granular fertilizer).

3. Expandability: Reserved interfaces are provided for future upgrades (such as automatic bag loading and robot palletizing), and it has stronger compatibility with bucket cranes.

Iv. Recommended Plan

Typical configuration: Bucket weighing packaging machine (such as DCS series) + automatic bag feeding machine + heat sealing machine, combined with vibrating screen for pre-treatment of materials.

Alternative solution: If the fertilizer is dried evenly, a doupless screw packaging machine (such as the TDB series) can be used, but an additional real-time moisture monitoring and clogging alarm system needs to be added.

Overall, large-scale chicken farms and fertilizer plants prefer bucket packaging machines because of their adaptability to complex materials and high precision, which better meet the demands of large-scale production. If the production is further subdivided in the later stage (such as processing high-end granular fertilizer), a bucket less machine can be supplemented to improve efficiency. It is essential to request the equipment manufacturer to provide material testing services to ensure the actual operation effect.
