Case Study: Packaging Chopped Lucerne Hay & Straw into 6–10 kg Stockfeed Bags
Customer Requirement
A livestock feed producer approached SINOBALER looking for a practical and cost-effective solution to package chopped lucerne (alfalfa) hay and chopped straw into small stockfeed bags.
The customer planned to supply packaged feed products to livestock farms and distributors and required a system capable of producing consistent bags weighing approximately 6–10 kg.
Customer Inquiry
"Looking to use the baler for chopped lucerne hay and straw. No specific weight requirements but around the 6–10 kg."
Challenges Faced
Loose chopped forage materials such as lucerne hay and straw present several packaging challenges:
- Low bulk density
- High storage volume
- Difficult handling and transportation
- Inconsistent manual bag filling
- Increased labor requirements
- Higher logistics costs
The customer needed a solution that could produce uniform feed bags while keeping equipment investment and operating costs under control.
Material Analysis
Materials to be Processed
- Chopped Lucerne (Alfalfa) Hay
- Chopped Straw
Material Characteristics
These materials are typically:
- Lightweight and fluffy
- Easy to compress
- Suitable for direct bagging after chopping
- Commonly used as livestock feed and bedding materials
Because the target package weight is relatively low at 6–10 kg per bag, a simple and economical bagging system is preferable to a fully automated packaging line.
SINOBALER Recommended Solution
SHB1-SW-100 Scale Weighing Horizontal Bagging Baler
After reviewing the customer's requirements, SINOBALER recommended the SHB1-SW-100 Scale Weighing Horizontal Bagging Baler.
This machine is specifically designed for packaging lightweight agricultural, biomass, and stockfeed materials into accurately weighed bags.
The SHB1-SW-100 combines weighing, compression, and bagging functions in a compact and user-friendly design, making it ideal for small and medium-sized feed packaging operations.
Why SHB1-SW-100?
Accurate Bag Weight Control
One of the key requirements was achieving consistent bag weights of approximately 6–10 kg.
The SHB1-SW-100 incorporates an integrated weighing system that automatically measures the material before each compression cycle.
Benefits include:
- Consistent bag weights
- Improved product quality
- Reduced material giveaway
- Better customer satisfaction
- Professional product presentation
Manual Feeding – The Most Economical Solution
For chopped lucerne hay and chopped straw, SINOBALER recommends manual feeding directly into the weighing hopper.
Because the material is lightweight and the target bag weight is relatively small, manual feeding offers significant advantages:
- Lower initial investment
- Simplified machine installation
- Reduced maintenance requirements
- Flexible operation
- Lower power consumption
- Easy material handling
In this application, a conveyor feeding system is generally unnecessary and would only increase project costs without providing significant operational benefits.
Semi-Automatic Operation
The SHB1-SW-100 provides a simple and efficient workflow.
The operator manually feeds the material into the weighing hopper and places an empty bag onto the discharge chute.
The machine then automatically performs:
- Material weighing
- Hydraulic compression
- Bag filling
- Bale discharge
This semi-automatic design provides an excellent balance between productivity and affordability.
High-Density Compression
The hydraulic compression system significantly reduces the volume of chopped forage materials.
Benefits include:
- Reduced storage space requirements
- Lower transportation costs
- Easier stacking and handling
- Improved warehouse efficiency
Recommended System Configuration
SINOBALER recommends the following configuration:
