Vacuum Packaging Machine | Food and Nut Packing Machine

The vacuum packaging machine is specifically designed for bulk foods and liquid-containing materials, enabling efficient sealing and packaging of granular, powdered, and block-shaped products.

Featuring a dual-chamber submersible vacuum structure and equipped with an industrial-grade vacuum pump, it achieves a vacuum level of 0.1 Pa with a pumping speed up to 40 m³/h, delivering stable, deep vacuum sealing in minimal time.

Constructed entirely from 304 stainless steel, the unit complies with food processing hygiene standards. It is suitable for small to medium-scale continuous production, effectively extending food shelf life while preserving original flavor and quality.

Applications of vacuum packaging machine

This packaging machine is widely used across multiple food and agricultural by-product processing sectors, including but not limited to:

• Grains and agricultural by-products: vacuum packaging of granular materials such as rice, beans, corn, coarse grains, seeds, etc.
• Nuts and roasted snacks industry: moisture-proof and oxidation-resistant packaging for nut products like melon seeds, peanuts, walnuts, and almonds.
• Liquid-containing or pickled foods: vacuum sealing for braised dishes, pickled products, and foods with sauces.
• Commercial and warehousing settings: facilities requiring standardized packaging, such as food processing plants, e-commerce warehouses, central kitchens, and chain restaurants.

Automatic vacuum packing machine features

Sunken vacuum chamber

The chamber features a sunken design to accommodate packaging bags of varying heights. During vacuuming, the bag opening remains above the liquid surface at all times, effectively preventing spills—ideal for soupy foods—while also achieving deep vacuuming for granular materials.

Efficient dual-chamber alternating operation

Left and right vacuum chambers operate alternately. While one side performs vacuuming and sealing, the other can load or unload bags, significantly boosting overall packaging efficiency.

Intelligent operation control

Equipped with a digital display control panel, it allows precise adjustment of vacuum level, sealing time, and sealing temperature. Compatible with various packaging materials, it offers simple operation and high stability.

Durable and stable industrial configuration

Key components such as the vacuum pump and sealing strip utilize industrial-grade specifications, featuring waterproof, oil-resistant, and wear-resistant properties. Suitable for long-term operation in humid and dusty environments.

Machine structure and working principle

This vacuum packaging machine primarily consists of a vacuum chamber, vacuum pump system, heat sealing system, electrical control system, and frame structure.

1. During operation, packaging bags filled with materials are placed into the submersible vacuum chamber.
2. Upon starting the equipment, the chamber automatically submerges and undergoes vacuum extraction.
3. Upon reaching the preset vacuum level, the heat sealing system seals the bag opening. The chamber then returns to its original position, completing the bag ejection.

The dual-chamber design enables continuous operation, ensuring a stable packaging rhythm and consistent sealing quality.
