Our Mixed Nuts Weighing & Filling Packaging Line is an integrated automatic jar packaging system specially engineered for granular nuts and dried fruit products. Composed of six core modules: Z-type elevator, multi-head combination weigher, bottle conveyor, precision filling unit, automatic jar capper and round bottle labeler. It completes automatic feeding, precise weighing, quantitative filling, jar sealing and labeling in one continuous workflow.
This fully automated packaging system solves common pain points in traditional nut packaging: large weighing errors, high material waste, low productivity and inconsistent packaging appearance. The whole line runs stably with strong adaptability for multiple jar sizes. Widely adopted by nut factories, dried fruit processors and snack food manufacturers for large-scale standardized production. It is the ideal intelligent packaging upgrade solution for dry snack production.
Suitable Materials & Packaging Containers
This production line is designed for irregular granular nuts and dried fruits with wide compatibility.
Mixed nuts: Almonds, cashews, walnuts, pistachios, hazelnuts, pine nuts, macadamia nuts, single or blended nut kernels
Dried fruit ingredients: Cranberries, raisins, dried blueberries, dried strawberries, mango strips and other blended dried fruits
Container compatibility: Round PET plastic jars, glass bottles, food-grade tin cans, custom round jars with different volumes available
Solve Key Industry Pain Points
Traditional manual nut packaging brings many production bottlenecks. Our full automatic packaging line addresses these challenges and helps food manufacturers cut costs, boost quality and meet compliance requirements.
Inaccurate manual weighing & high material waste Manual filling relies on visual estimation, with 3%–5% weight error per jar. Manufacturers overfeed to avoid underweight complaints, resulting in 8%–15% raw material loss. Our multi-head combination weigher delivers stable, controllable weighing accuracy.
High labor cost & limited throughput Separate manual work for feeding, weighing, filling, capping and labeling slows production. Our linked automatic line minimizes manual intervention and raises output while cutting labor expenses.
Material breakage & product loss Manual filling often spills or squeezes nuts, causing breakage. Z-type elevator and soft discharging reduce collision damage, lowering material waste below 1%.
Poor sealing & inconsistent packaging quality Hand-sealed jars have uneven tightness, prone to moisture and oxidation. Automatic capping creates airtight seals; auto labeling delivers neat, aligned labels to unify product appearance.
Unstable output hard for bulk orders Manual production fluctuates and struggles with large orders. Continuous high-speed automatic operation delivers stable throughput for mass standardized manufacturing.
Core Product Advantages
1. Full Automatic Linked Operation, Integrated Efficient Workflow
Six modular units connect seamlessly. Feeding, weighing, blending, filling, capping and labeling run continuously on one pipeline. One-button start, stop and speed adjustment reduces manual attendance and keeps consistent production flow.
2. Precise Weighing with Multi-head Combination Weigher
High-precision multi-head combination weigher uses intelligent weight combination calculation. Small weighing error ensures stable dosing and reduces overfeeding waste.
3. Gentle Conveying & Filling to Protect Kernels
Z-type elevator delivers smooth vibration feeding to prevent material stacking, bridging and spillage. Low-speed soft filling minimizes nut collision and breakage, preserving intact kernel appearance and product quality.
4. Robust Construction for Long-Term Mass Production
Solid machine frame and premium key components offer high wear resistance and low failure rate. Supports long-hour continuous high-speed operation for non-stop factory batch production.
5. Flexible & Adjustable for Multiple Products
Quick parameter adjustment for different materials, jar dimensions and target filling weights. Compatible with a wide range of round jars and cans. One packaging line handles multiple nut products to maximize equipment utilization.
6.Superior Packaging Performance
Automatic capping achieves excellent airtightness to block air and moisture, preventing nut oxidation and dampness to extend shelf life. Round bottle labeler applies labels flat without wrinkles or skew for premium uniform finished packaging.
