Single Chamber Vacuum Packing Machine

Product Overview

This single chamber vacuum packing machine is designed to extract air from filled pouches and seal the pouch opening inside an enclosed vacuum chamber. The series includes compact and floor-standing models with different sealing lengths, chamber depths, machine dimensions, and power ratings.

During operation, the product is placed inside a compatible heat-sealable pouch. The complete pouch is positioned inside the chamber, with its open edge lying across the sealing strip. Once the cover is closed, air is removed from the chamber and the pouch. The heating strip then seals the pouch before normal atmospheric pressure is restored.

The machine is suitable for food processors, butcher shops, seafood suppliers, restaurants, central kitchens, agricultural-product packers, retail food producers, and businesses packaging compatible hardware or industrial parts. It can be used for dry products and moist products when the correct pouch, vacuum setting, sealing time, and product placement are selected.

The enclosed chamber structure allows the machine to process smooth vacuum pouches and provides more controlled vacuuming than an external suction system. Final packaging results depend on the pouch material, product temperature, moisture content, package size, chamber depth, and selected operating settings.

Applications

This machine is suitable for products that can be placed inside a compatible heat-sealable vacuum pouch and fit completely within the selected chamber. Product temperature, moisture content, sharp edges, package height, and pouch structure should be checked before production.

This machine is suitable for:

• Fresh meat
• Processed meat
• Poultry portions
• Fish and seafood
• Cooked food
• Prepared meals
• Cheese
• Dried fruit
• Rice
• Beans and pulses
• Nuts and seeds
• Grain products
• Dried chilies and spices
• Soup ingredients
• Compatible hardware components

A packaging test is recommended for products containing free-flowing liquid, sharp bones, hot ingredients, excessive moisture, fragile pieces, or irregular edges. Suitable pouch thickness and puncture resistance should be confirmed before use.

Main Features

1. Single Chamber Structure

The complete filled pouch is placed inside one enclosed chamber, where vacuum extraction and heat sealing are completed during the same operating cycle.

2. Integrated Vacuum and Sealing

The machine automatically performs chamber evacuation, pouch sealing, pressure equalization, and cycle completion after the operator closes the chamber cover.

3. Multiple Sealing Lengths

The documented series provides sealing lengths from 320 to 620 mm, allowing customers to select a machine according to the required pouch width.

4. Dry and Moist Packaging

The machine can process suitable dry and moist products when the pouch material, chamber capacity, sealing time, and vacuum settings are correctly matched.

5. Adjustable Operating Controls

The front control panel allows operators to adjust the vacuum and sealing process according to the product and pouch being packaged.

6. Tabletop and Floor-Standing Options

The series includes a compact tabletop model and larger floor-standing machines for different working spaces, package sizes, and production requirements.

7. Stainless-Steel Construction

The supplied product information specifies stainless-steel construction, supporting routine cleaning and commercial food-packaging applications.

8. Multiple Chamber Sizes

Different chamber depths and machine dimensions are available, helping customers accommodate packages with different widths, lengths, and product heights.

9. Broad Pouch Compatibility

The machine can process compatible smooth, textured, laminated, duplex, and aluminum-foil pouches when their inner layers support heat sealing.

Working Principle

The operator places the product inside a suitable vacuum pouch and leaves enough clean pouch material at the opening for sealing. The filled pouch is placed completely inside the chamber, with its open edge positioned flat across the sealing strip.

After the cover is closed, the vacuum system removes air from the enclosed chamber. As chamber pressure decreases, air is extracted from the pouch. When the preset vacuum stage is completed, the heating strip closes the pouch opening.

The machine then stops vacuum extraction and restores the chamber to normal atmospheric pressure. The chamber cover releases, and the operator removes the completed package before loading the next pouch.

Vacuum time, sealing time, product temperature, pouch thickness, and package positioning should be adjusted according to the actual product and packaging material.

Process Flow:

Product Loading → Pouch Positioning → Chamber Closing → Vacuum Extraction → Heat Sealing → Pressure Equalization → Cover Opening → Package Removal

Machine Details

1. Vacuum Chamber

The chamber accommodates the complete product pouch during vacuum extraction. Its usable width, length, and depth determine the maximum package dimensions.

2. Vacuum Cover

The cover closes against the chamber gasket to create the sealed environment required for vacuum extraction.

3. Chamber Sealing Gasket

The gasket runs around the chamber opening and helps maintain an airtight connection between the machine body and the closed cover.

4. Sealing Bar

The open end of the pouch is placed across the sealing bar before the vacuum cycle begins. The available sealing length varies by model.

5. Heating Strip

The heating strip applies controlled heat to the pouch after vacuum extraction, bonding the compatible inner sealing layers together.

6. Vacuum Suction Port

The suction port connects the chamber to the vacuum system and removes air during the packaging cycle.

7. Control Panel

The front control panel provides access to operating settings, cycle controls, and packaging adjustments.

8. Vacuum Gauge

Selected configurations include a front-mounted vacuum meter for observing pressure changes during operation.

9. Lid Support Damper

The lid-support mechanism assists with controlled opening and closing of the chamber cover during loading and unloading.

10. Mobile Machine Base

Larger floor-standing models are equipped with caster wheels for positioning and cleaning access. The machine should be secured before operation.

Technical Parameters

Packaging & Shipping

The supplied materials do not confirm the final export packing dimensions, gross weight, delivery time, or shipping terms. These details should be calculated after the customer selects the sealing length, chamber size, voltage configuration, and any required accessories.

Before shipment, the chamber, sealing strip, vacuum operation, control settings, and electrical configuration should be checked against the confirmed order. Testing with the customer’s actual pouch is recommended when the material or thickness differs from standard samples.

The machine should be cleaned, protected from moisture, and securely fixed to prevent movement during transportation. The final packing method, shipping dimensions, and gross weight will be confirmed according to the selected machine configuration.

Freight, customs clearance, import duties, destination charges, and local delivery should be agreed separately with the buyer.

FAQ

Q1: What products can the single chamber vacuum packing machine package?

It can package suitable meat, seafood, poultry, cooked food, grains, rice, beans, nuts, dried fruit, spices, cheese, prepared food, and compatible non-food products. The product and filled pouch must fit completely inside the selected vacuum chamber.

Q2: How should the correct machine size be selected?

Please confirm the filled pouch width, pouch length, package height, required sealing length, product type, daily output, and available working space. The chamber must accommodate the complete package without folding or interfering with the sealing area.

Q3: Can this machine package moist food?

The machine can process suitable moist products, but the product temperature, liquid content, chamber depth, pouch position, and vacuum time must be controlled. A packaging test is recommended for products containing free-flowing liquid.

Q4: What type of vacuum pouch should be used?

The pouch must have a heat-sealable inner layer and sufficient strength for vacuum packaging. Smooth, textured, laminated, duplex, and aluminum-foil structures may be suitable when their material and sealing temperature match the machine.

Q5: What is the difference between the available models?

The main differences are sealing length, chamber depth, machine dimensions, weight, and power. The smaller model is suitable for compact packages, while the larger models accommodate wider pouches and larger products.
