Dedicated to Dried Fruit and Nut Processing Plants: Application Advantages and Solutions of Pouch Packaging Machines

In the dried fruit and nut processing industry, the packaging stage not only affects production efficiency but also directly relates to product freshness and brand image. Pouch packaging machines, with their core advantages of strong adaptability to pre-made bags, precise metering, and reliable sealing, have become the ideal choice for large-scale packaging of dried fruits and nuts, perfectly solving the pain points of traditional packaging such as "low efficiency, high loss, and poor quality."

针对 dried fruits and nuts (such as raisins, red dates, walnuts, cashews, and mixed nuts) with their granular, blocky, and irregular shapes, the pouch packaging machine completes the packaging through a 5-step automated process, requiring no manual intervention:

1. Bag picking: A vacuum suction cup picks up a pre-made bag from the bag storage (stand-up pouches, zipper bags, and three-side seal bags are all compatible), adapting to the common high-end packaging bag types for dried fruits and nuts;
2. Bag opening and detection: Mechanical grippers open the bag mouth, equipped with a photoelectric detection device. If the bag mouth is not opened or the bag is damaged, it is automatically rejected to prevent material spillage;
3. Precise metering and filling: Equipped with an electronic combination scale (core matching component), it achieves precise weighing (error ±1g) for dried fruits and nuts with uneven sizes and varying specific gravity, supporting quantitative filling of single or mixed nuts, eliminating underfilling and overfilling problems;
4. Exhaust and sealing: After filling, the air inside the bag is first expelled (to prevent bag expansion and damage during transportation, and to extend the shelf life of the dried fruit), and then the bag mouth is sealed by heat sealing or ultrasonic sealing. The high sealing strength effectively isolates air and moisture, preventing oxidation and dampness of dried fruits and nuts;
5. Finished product output: The packaged finished products are transported to the next stage, supporting the integration of coding and labeling equipment to print production date, shelf life, and batch number, meeting product traceability requirements.

• Flexible bag types, enhancing brand value: Supports high-end pre-made bag types such as stand-up pouches, zipper bags, and window bags, allowing direct use of beautifully printed brand packaging bags without on-site bag making. Compared to pillow-type packaging machines using roll film, bag-type packaging produces a more high-end finished product, suitable for gift and retail packaging of dried fruits and nuts, helping to increase product price and brand image.
• Precise metering reduces material loss: The multi-head electronic combination scale, specially designed for dried fruits and nuts, can quickly adapt to materials of different particle sizes (such as large walnuts and small raisins), with a weighing accuracy of up to ±1g, far exceeding the accuracy of manual weighing. It also features "no bag, no filling" and "abnormal weight rejection" functions to prevent material waste and reduce production costs.
• Reliable sealing extends shelf life: Using precise temperature-controlled heat sealing technology, it can adjust the optimal sealing temperature and pressure for composite films and aluminum foil films commonly used in dried fruit and nut packaging, achieving high airtight sealing. Combined with the exhaust function, it reduces oxygen residue in the bag, effectively preventing oxidation, moisture absorption, and mold growth in dried fruits and nuts, significantly extending the product's shelf life (extending it by 3-6 months compared to ordinary packaging).
• Efficient automation, suitable for large-scale production: Packaging speed can reach 30-100 bags/minute (adjustable according to bag type and material), far exceeding manual packaging efficiency. It can be seamlessly integrated with the front-end dried fruit and nut sorting and drying production line, achieving full-process automation from "cleaning - drying - sorting - packaging," reducing the risk of contamination from manual contact and lowering labor costs, breaking through production bottlenecks.
• Convenient operation and quick product switching: Equipped with a touch screen human-machine interface, pre-set packaging parameters for different dried fruits and nuts (such as 500g/bag of red dates, 200g/bag of mixed nuts), allowing for one-click parameter recall when switching products, eliminating the need for complex debugging. The modular design of core components makes disassembly and cleaning easy, meeting the hygiene standards of the food processing industry.

• Single-product packaging: Quantitative packaging of single types of dried fruits and nuts such as raisins, red dates, goji berries, almonds, and cashews;
• Mixed packaging: Combination weighing and packaging of multiple materials such as daily nuts and mixed dried fruits;
• Different specifications packaging: Supports flexible switching between small packaging (20g sample pack), medium packaging (200g retail pack), and large packaging (1kg family pack).

When purchasing a pre-made pouch packaging machine for dried fruit and nut processing plants, three key points should be considered:

• Metering configuration: Prioritize models equipped with multi-head electronic combination scales to accommodate the irregular shapes of dried fruits and nuts;
• Bag type compatibility: Confirm that the equipment supports commonly used bag types (such as zipper stand-up pouches) to avoid the hassle of replacing fixtures later;
• Hygienic design: Choose models with a 304 stainless steel body and easy-to-clean structure to meet food processing hygiene requirements.

In short, pre-made pouch packaging machines provide dried fruit and nut processing plants with an "efficient, precise, and high-end" packaging solution. They can improve production efficiency, reduce costs, and enhance product market competitiveness through high-quality packaging. They are essential equipment for dried fruit and nut processing enterprises to achieve large-scale and brand-oriented development.
