Product Description
- Product Details & Technical Specifications
Elevate Your Macadamia Processing Operations Maximize throughput and optimize kernel quality with our turnkey Industrial Macadamia Nut Processing Line. Engineered for high-capacity agricultural processing facilities, this complete production line is designed to transform raw macadamia nuts into cleanly sorted, premium kernels at an impressive rate of 1000kg per hour.
With a streamlined workflow that automates grading, shelling, and optical sorting, this machine line drastically reduces manual labor while achieving a 90% whole kernel rate, ensuring maximum profitability for your operation.
The 3-Step Processing Workflow
Step 1: Precision Grading (Drum Screen Classifier) Raw macadamia nuts are fed into the drum screen classifier, which automatically sorts the nuts into up to 4 different diameter sizes. Pre-grading is critical to ensure high cracking efficiency and to maximize the whole kernel rate during the shelling phase.
Step 2: Adjustable Roller Shelling The graded nuts are conveyed to the dual shell-breaking machines. The roller gap can be precisely adjusted to match the specific size of the macadamia nuts. By processing sorted sizes individually, the rollers apply optimal pressure to crack the shell without crushing the kernel inside. The system is designed to shell 2 sizes directly and collect the other 2 sizes for seamless batch processing.
Step 3: Optical Color Sorting & Separation After shelling, the mixture of kernels and shells is transported to the HL-LCS2 Color Sorting Machine. This high-efficiency optical sorter flawlessly separates the macadamia kernels from the broken shells. By removing shells quickly and efficiently, the color sorter also significantly reduces the oil rate of the macadamia nuts, preserving the freshness, quality, and shelf-life of the final product.
Operational Efficiency & Resource Allocation
This production line is optimized for industrial efficiency, requiring minimal resources to run at peak capacity:
