Multifunctional Fully Automatic Food Packaging Machine for Nuts, Potato Chips, Biscuits, Candy, Peanuts, Beans, and Rice

The "Bagged Nut Packaging Machine" is a highly specialized piece of equipment used in the food processing industry.

I. Introduction to the Bagged Nut Packaging Machine

A bagged nut packaging machine is an automated or semi-automated machine specifically designed to fill and seal various nuts (such as walnuts, almonds, cashews, macadamia nuts, and peanuts) into bags according to preset weights. It significantly improves production efficiency, ensures packaging quality and hygienic standards, and is a core piece of equipment for modern nut processing companies.

II. Main Types

Based on the degree of automation and packaging format, these machines are primarily categorized as follows:

1. Stand-Up Pouch Packaging Machine

Working Principle: On-site bagging, filling, and sealing are performed using roll film. Starting with a roll of packaging film, a former forms it into a tube, sealing the edges longitudinally. A transverse sealing mechanism then seals the bottom, filling the bag with the product, and finally sealing and cutting the bag at the top to form a complete bag.

Advantages: A variety of packaging styles (such as back-seal, three-side seal, and four-side seal) are available, space is saved, and material changeovers are flexible.

Application: Suitable for small-size packaging (a few grams to 1 kilogram) of small and medium-sized nuts (such as peanuts, melon seeds, and almonds).

2. Bag-feeding Packaging Machine

Working Principle: Using pre-made bags, the machine automatically removes the bags, opens them, fills them with the material, and then seals them (e.g., heat-sealing, thread-sealing, or zipper-sealing).

Advantages: Offers a variety of attractive bag shapes (such as stand-up pouches, zipper bags, and custom-shaped bags), easily implements nitrogen filling for freshness preservation, and is fast.

Application: Suitable for packaging of various sizes and bag types, especially for high-end nut products that require nitrogen filling for freshness preservation.

3. Weighing Method Classification

Single-hopper weighing: Simple structure and low cost, but slow speed and average accuracy.

Combination weigher (multi-head computer combination weigher): Consists of multiple weighing hoppers. A computer calculates the weights of the multiple hoppers and combines them to obtain the combination closest to the target weight for filling.

Advantages: Extremely high accuracy (up to ±0.1-1 gram) and high speed make it the mainstream and high-precision choice for nut packaging.

Applicable to: All automated packaging lines with strict weight requirements.

III. Core Components

A complete bagged nut packaging machine typically includes the following systems:

Loading System: Nuts are transported to the packaging machine's storage hopper via an elevator, vibrating plate, or conveyor belt.

Weighing System: The core component, such as a combination scale or single-hopper scale, is responsible for accurately measuring the weight of each bag.

Bag Forming and Filling System (Vertical Machine) or Bag Opening System (Bag Feeder): Completes bag formation or preparation.

Nitrogen Filling System (Optional): Before sealing, the bag is de-aired and filled with nitrogen to extend the shelf life of the nuts and prevent oil oxidation.

Heat Sealing System: A heating element seals the bag opening.

Coding System: Prints information such as the production date and batch number on the bag.

Control System: A PLC (Programmable Logic Controller) and touchscreen human-machine interface are used to set parameters, control the entire process, and monitor operating status.

IV. Summary and Recommendations

Small Businesses/Startup Brands: Start with a semi-automatic packaging machine (manual bag placement, machine weighing and filling) or a basic vertical combination weigher packaging machine. These offer low investment and high flexibility.

Medium-Sized and Larger Businesses: We recommend fully automatic bag-feeding packaging machines or high-speed vertical packaging machines, equipped with combination weighers and nitrogen filling capabilities, to meet high-volume, high-quality, and long-shelf-life production needs.

High-End Product Line: Bag-feeding nitrogen filling packaging machines are the preferred choice, providing the most beautiful packaging appearance and optimal freshness preservation.
