Nut, Peanut, and Crispy Freeze-Dried Products Packaging Line With Weighing Filling、Nitrogen Sealing and Labeling Machine

GZFharvest Fully Automated Freshness-Locking Canning and Packaging Line for Nuts and Granules

In the snack packaging industry, peanuts, various nuts, and freeze-dried granules have always presented packaging challenges! The materials are brittle and fragile, highly susceptible to moisture absorption and oxidation, easily accumulate dust and impurities inside the cans, and suffer from poor packaging standardization. These issues not only affect product appearance but also directly shorten shelf life and negatively impact product reputation.

To address the packaging pain points of high-end granular foods, GZFharvest has launched a fully automated canning and packaging line specifically for peanuts, nuts, and freeze-dried granules. The entire production line is fully equipped with a closed-loop process, automating everything from empty can cleaning to finished product collection!

Seven Key Equipment Units Working in tandem

Unlike simple packaging production lines, our customized production line is equipped with a complete set of specialized equipment, each performing its specific function and seamlessly integrated to meet the mass production needs of various food can types:

🔹 Fully Automatic Bottle unscrambler
Intelligently sorts and arranges disordered empty cans, automatically sorting and directional conveying them. Stable operation prevents can jamming and tipping, requiring no manual intervention for can loading. Improves the overall production line's operating speed from the source, suitable for high-speed mass production scenarios.

🔹 Empty Can Air Cleaning Machine
A dedicated pre-cleaning process uses high-pressure, dust-free airflow to thoroughly clean dust, debris, and impurities from inside the cans, completely eliminating hygiene dead spots and preventing impurities from mixing into the materials. Strictly compliant with food safety production standards, suitable for high-end snack quality inspection standards.

🔹 High-Precision Weighing and Filling Machine
Optimized feeding structure for nuts and freeze-dried fragile materials, flexible filling prevents material compression and breakage. Accurate and stable weighing and measurement with controllable weight error. Supports one-click switching between multiple product specifications, balancing mass production speed and finished product qualification rate, significantly reducing material loss costs.

🔹 Nitrogen-Filled Can Sealing Machine
Equipped with vacuum nitrogen-filled preservation technology, it replaces oxygen inside the can, effectively preventing nuts from becoming damp, oils from oxidizing, and freeze-dried foods from discoloring and spoiling. The seal is tight and flat, with excellent airtightness, effectively locking in the crisp texture and freshness of the ingredients, significantly extending product shelf life.

🔹 Fully Automatic Labeling Machine
Intelligent and precise labeling, adaptable to various sizes of round cans and food containers. Labels are applied smoothly without bubbles, misalignment, or wrinkles, ensuring consistent product packaging aesthetics and helping products stand out on retail shelves.

🔹Coding Machine
The coding process is completed synchronously on the production line, clearly printing production date, batch number, and traceability code. The lettering is strong, wear-resistant, and not easily detached, eliminating the need for secondary manual coding and meeting the traceability requirements of supermarkets, e-commerce, and foreign trade channels.

🔹 Automatic Bottle Collector
Finished cans are automatically and orderly collected and discharged, replacing traditional manual picking and handling. This simplifies back-end processes, significantly reduces labor costs, and allows for direct integration with packing and warehousing processes, enabling full automation of the entire process.

Widely compatible materials: Various peanut products, almonds, cashews, walnuts, hazelnuts, mixed nuts, freeze-dried fruit pieces, freeze-dried vegetable pieces, crispy granule snacks, etc.
