Automatic Chestnut & Nut Premade Pouch Packaging Machine

1. Packaging Video and Working Process

Automatic Chestnut Packaging Process

The Z-type bucket elevator automatically conveys chestnuts to the 10-head combination weigher. After the product reaches the preset target weight, the weighed chestnuts are discharged into the premade pouch packaging machine for automatic packaging.

The packaging machine completes the following operations:

1. Automatic Pouch Picking: The machine automatically picks up a premade pouch and transfers it to the next station.
2. Date Coding: The production date or batch information is printed on the pouch when the coding device is installed.
3. Pouch Opening: The machine automatically opens the pouch in preparation for product filling.
4. Product Filling: The weighed chestnuts are discharged from the combination weigher into the opened pouch.
5. Pouch Mouth Adjustment: The machine organizes and aligns the pouch opening before sealing.
6. First Sealing: The pouch undergoes the first heat-sealing operation.
7. Second Sealing: A second heat-sealing operation completes the package closure.
8. Finished Bag Output: The sealed packages are automatically discharged from the machine.

Complete Packaging Process:

Chestnut Feeding → Z-Type Bucket Elevator → 10-Head Combination Weigher → Automatic Pouch Picking → Date Coding → Pouch Opening → Product Filling → Pouch Mouth Adjustment → First Sealing → Second Sealing → Finished Bag Output

2. Key Advantages and Features

1. Automatic Premade Pouch Packaging

The machine automatically completes pouch picking, opening, filling, and sealing. The coordinated packaging process reduces manual operations and helps improve production efficiency.

2. Wide Range of Packaging Bags

Suitable for various premade bags, including multilayer laminated plastic bags and paper bags. Different packaging materials can be selected according to product and packaging requirements. The system helps reduce packaging material loss while providing reliable sealing quality.

3. Quick and Easy Packaging Size Adjustment

Changing packaging specifications is convenient. The width of the automatic pouch feeding device can be adjusted using a handwheel, making it easier to accommodate different pouch widths and improve changeover efficiency.

4. Intelligent Detection to Reduce Material Waste

The machine is equipped with a detection system. If no pouch is present or a pouch is not properly opened, the system detects the condition and prevents the filling and sealing devices from performing their corresponding operations. This helps avoid product spillage and unnecessary pouch waste.

5. Variable Frequency Speed Control

The machine adopts a variable frequency speed control system. Packaging speed can be adjusted within the permitted operating range according to product characteristics, pouch specifications, and production requirements.

6. PLC Touchscreen Control System

The machine uses a PLC control system with a touchscreen human-machine interface. Operating parameters can be set conveniently, making daily operation and production management easier.

7. 10-Head Combination Weigher

Equipped with a 10-head combination weigher, the system calculates suitable combinations from multiple weighing hoppers to achieve the target package weight. It is suitable for chestnuts, nuts, and other solid food products with different shapes and sizes.

8. Automatic Z-Type Feeding System

The Z-type bucket elevator automatically conveys chestnuts to the combination weigher, reducing manual handling and helping maintain a continuous feeding process.

9. Two-Stage Heat Sealing

After the pouch opening is organized, the machine performs two sealing operations to complete the package closure and produce neat finished packages.

7. Frequently Asked Questions

Q1: What products can this premade pouch packaging machine pack?

It is suitable for chestnuts, almonds, peanuts, cashews, sunflower seeds, pumpkin seeds, mixed nuts, and other compatible solid or granular food products. The feeding and weighing configuration should be selected according to the actual product.

Q2: How does the automatic chestnut packaging line work?

First, the Z-type bucket elevator conveys chestnuts to the 10-head combination weigher. After weighing, the product is discharged into the premade pouch packaging machine. The machine automatically picks up the pouch, prints the date when configured, opens the pouch, fills the product, adjusts the pouch opening, performs two-stage sealing, and outputs the finished package.

Q3: What is the packaging speed?

The listed packaging speed is 25–60 bags per minute. Actual speed depends on the product, target package weight, pouch size, and operating conditions.

Q4: What types of packaging bags can the machine use?

The machine can be configured for four-side seal bags, zipper stand-up pouches, and eight-side seal zipper pouches. It can also handle suitable multilayer laminated plastic premade bags and paper bags. Please provide a pouch sample or size drawing so that our team can confirm compatibility.

Q5: Will the machine continue filling if there is no pouch or the pouch is not properly opened?

No. The machine is equipped with a detection system. If no pouch is detected or the pouch is not properly opened, the system prevents the filling and sealing devices from performing their corresponding operations. This helps reduce product spillage and packaging material waste.

Q6: Is Soonkpack a packaging machine manufacturer or a trading company?

Foshan Soonk Packaging Machine Co., Ltd. (Soonkpack) is a packaging machinery manufacturer located in Foshan, Guangdong, China. Established in 2008, the company provides packaging machine design, manufacturing, installation guidance, and after-sales support.
