external vacuum machine, also known as an external vacuum packaging machine, is a type of vacuum packaging equipment that operates by applying vacuum externally to the packaging material. Unlike internal vacuum machines, where the vacuum is created within a chamber around the product, external vacuum machines use external mechanisms to remove air from the packaging. This type of machine is commonly used for various applications, including food packaging, pharmaceuticals, and industrial products.

What is an External Vacuum Machine?

• Definition: An external vacuum machine removes air from the package using an external vacuum pump. The process involves placing the packaging bag or material within a sealing bar or chamber, applying vacuum from outside, and then sealing the package.

Components:

1. Vacuum Pump: Removes air from the package or vacuum bag. This is often an external pump connected to the machine.
2. Sealing Bar: Seals the package tightly after the air has been removed. The sealing bar may be integrated into the machine or used separately.
3. Packaging Bag/Film: The material in which the product is placed. It is often a flexible, vacuum-sealable bag or roll stock.
4. Control Panel: Allows operators to set parameters such as vacuum levels, sealing times, and other operational settings.
5. Hose/Connector: Connects the vacuum pump to the packaging bag or chamber to facilitate air removal.

Operation:

1. Loading: The product is placed into a vacuum-sealable bag or film.
2. Air Removal: The open end of the bag is placed in the vacuum machine, and the vacuum pump is activated to remove air from the bag.
3. Sealing: Once the desired level of vacuum is achieved, the bag is sealed using the sealing bar to prevent air from re-entering.
4. Ejection: The sealed package is removed from the machine, and the process is ready to be repeated.

Types of External Vacuum Machines:

1. External Vacuum Sealers: Typically used for home or small-scale commercial applications. They often come with a sealing bar and an integrated vacuum pump.
2. External Vacuum Packaging Systems: Larger, more industrial machines designed for high-volume packaging. They may have advanced features and automated processes for efficiency.

Applications:

• Food Industry: Used to package meats, cheeses, snacks, and other perishable items to preserve freshness and extend shelf life.
• Pharmaceuticals: Ideal for packaging pills, powders, and other products that need to be kept in a controlled environment.
• Industrial Products: Used for packaging electronic components, parts, and other items that require protection from moisture and air.

Advantages:

• Cost-Effective: Often more affordable compared to chamber-based vacuum systems, making them suitable for small to medium-sized operations.
• Ease of Use: Simple to operate and maintain, with less complex mechanisms compared to chamber vacuums.
• Flexibility: Can accommodate various sizes and shapes of packaging bags, allowing for versatile use.
• Space Efficiency: Typically requires less space compared to larger chamber systems.
