Commercial Double Chamber Vacuum Packing Machine

Product Overview

This double chamber vacuum packing machine is designed for commercial and industrial applications requiring more continuous production than a single chamber machine. It has two working chambers positioned on opposite sides of a movable vacuum cover. The operator loads filled pouches into one chamber while the other side completes the vacuum and sealing cycle.

During operation, the open ends of the filled pouches are positioned across the sealing bars. The vacuum cover is moved over the loaded chamber, and the machine extracts air from the enclosed space. After the preset vacuum stage, the sealing system closes the pouch openings. Chamber pressure then returns to normal, allowing the completed packages to be removed.

The double chamber structure reduces idle loading time because the unused side can be prepared while the active chamber is operating. It is suitable for meat-processing plants, seafood factories, central kitchens, cooked-food producers, agricultural-product packers, dry-food factories, and other businesses handling repeated packaging batches.

Final packaging performance depends on the selected machine size, pouch dimensions, product height, moisture level, sealing compatibility, product temperature, and required vacuum level.

Applications

This machine is suitable for products placed in compatible heat-sealable vacuum pouches. The filled package must fit within the selected chamber, and the pouch opening must lie flat across the sealing bar.

This machine is suitable for:

• Fresh meat
• Processed meat
• Beef and lamb cuts
• Poultry portions
• Fish
• Shrimp and shellfish
• Other seafood products
• Cooked food
• Prepared meals
• Cheese products
• Rice
• Beans and pulses
• Nuts and seeds
• Dried fruit
• Spices and dried chilies

It can also package compatible hardware parts and other non-food products requiring reduced air exposure. A packaging test is recommended for sharp products, free-flowing liquids, hot food, fragile products, or packages with irregular edges.

Main Features

1. Double Chamber Configuration

Two working chambers share one movable vacuum cover, allowing the operator to prepare products on one side while the other side completes vacuuming and sealing.

2. Reduced Loading Downtime

The alternating chamber arrangement reduces waiting between cycles and is better suited to repeated commercial production than a conventional single chamber structure.

3. Integrated Vacuum and Sealing

Vacuum extraction, pouch sealing, pressure equalization, and cycle completion are performed inside the enclosed working chamber.

4. Dry and Moist Product Packaging

The machine supports compatible dry and moist products when the pouch material, product temperature, vacuum time, and sealing settings are correctly selected.

5. Multiple Machine Sizes

The documented series includes five machine sizes with different dimensions, weights, power requirements, and working widths for different package and production requirements.

6. Adjustable Control Panel

The front-mounted control panel allows operators to manage the vacuum and sealing process according to the product and packaging material.

7. Movable Vacuum Cover

The vacuum cover can be shifted between the two chambers using the upper handle and support structure, enabling alternating left-and-right operation.

8. Stainless-Steel Machine Body

The machine uses a stainless-steel body suitable for routine cleaning and commercial food-packaging environments, subject to the final material specification.

9. Floor-Standing Mobile Structure

The documented machines are floor-standing units fitted with universal caster wheels for workshop positioning and cleaning access.

10. Wide Application Range

The machine can be used for meat, seafood, cooked products, grains, dry foods, seasonings, and compatible non-food items packed in suitable vacuum pouches.

Working Principle

The operator first places each product inside a suitable heat-sealable vacuum pouch. The filled pouches are arranged inside one working chamber, with their open ends positioned flat across the sealing bars.

The movable vacuum cover is shifted over the loaded chamber. After the chamber closes, the vacuum system removes air from the enclosed space and from the pouches. When the preset vacuum stage is completed, the sealing pressure mechanism presses the pouch openings against the heated sealing bars.

The pouches are sealed, chamber pressure returns to normal, and the cover can then be moved to the second chamber. While the second chamber is operating, the operator removes finished packages and reloads the first chamber.

This alternating process reduces waiting time between loading and vacuum cycles. Vacuum time, sealing time, pouch thickness, product temperature, and package position should be adjusted according to the actual product.

Process Flow:

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

Machine Details

1. Dual Vacuum Chambers

The machine contains two separate working chambers. Each chamber holds filled pouches during vacuum extraction and sealing, allowing alternate-side production.

2. Movable Vacuum Cover

The upper cover moves between the two chambers and creates the enclosed working space required for vacuum extraction.

3. Operating Handle

The handle allows the operator to guide the vacuum cover from one chamber to the other during alternating production.

4. Sealing Bars

The pouch openings are positioned across the sealing bars before the chamber closes. The sealing bars apply heat after the vacuum stage.

5. Sealing Pressure Rod

The pressure structure holds the pouch opening against the sealing area during the heating stage, supporting stable contact between the bag and sealing bar.

6. Vacuum Extraction System

The vacuum system removes air from the enclosed chamber and the filled pouches before sealing begins.

7. Control Panel

The front control panel provides access to vacuum, sealing, and operating-cycle settings. Exact control functions depend on the selected configuration.

8. Cover Support Mechanism

The cover-support arms connect the movable lid to the machine body and guide its movement between the two chambers.

9. Heat Dissipation Openings

Ventilation openings on the side of the machine body support heat release from the internal electrical and vacuum components.

10. Universal Caster Wheels

Caster wheels support movement and workshop positioning. The machine should be placed on a stable surface and secured before production.

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 required chamber width, voltage, machine model, and any additional accessories.

Before shipment, the vacuum chambers, movable cover, sealing bars, control panel, vacuum cycle, sealing operation, and electrical configuration should be checked against the confirmed order. Testing with the customer’s actual pouch is recommended when the pouch material, thickness, or package dimensions differ from the available 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, import duties, customs clearance, destination charges, and local delivery should be agreed separately with the buyer.

FAQ

Q1: What is the advantage of a double chamber vacuum packing machine?

The two chambers allow alternating operation. While one chamber performs vacuum extraction and sealing, the operator can remove finished packages and prepare the other chamber. This reduces loading downtime and supports more continuous commercial production.

Q2: What products can this machine package?

It can package suitable meat, seafood, poultry, cooked food, grains, rice, beans, nuts, dried fruit, seasonings, cheese, and compatible non-food products. The filled pouch must fit inside the selected chamber and be compatible with heat sealing.

Q3: Can the machine package moist products?

Suitable moist products can be packaged, but product temperature, liquid content, pouch position, vacuum time, and chamber capacity must be controlled. Products containing free-flowing liquid should be tested before the final configuration is confirmed.

Q4: How should the correct machine size be selected?

Please provide the filled pouch width, pouch length, package height, number of pouches per cycle, product type, required daily output, and local voltage. These details determine the required chamber width, machine dimensions, and power specification.

Q5: What type of pouch is required?

The pouch must be suitable for vacuum packaging and have a compatible heat-sealable inner layer. Smooth laminated vacuum pouches, suitable composite bags, and some aluminum-foil structures may be used after sealing and vacuum tests.
