Double chamber vacuum packaging machine options

Double chamber vacuum packaging machine has more than 10 variations that are different in several factors, including:

1. Sealing wire length: From small to large size double chamber vacuum packaging machines, the sealing bar length could be 500mm/600mm/700mm/800mm/900mm. The sealing bar length determines the first part of the model number, for example, LDZ600/2S, means the sealing bar length is 600 mm.

2. Sealing wire quantity: The quantity of sealing bars in 1 chamber, usually 2 PCs or 4 PCs. Vacuum packing machines with 4 PCs sealing bars are usually made for very small packages with lengths around 10 centimeters. The sealing wire quantity determines the last part of the model number, for example, LDZ600/4S, means the sealing wire quantity in each chamber is 4 PCs.

4 sealing bars for small packages

Regularly 2 sealing bars

3. Working plate style: Flat or deep cavity. Regular models of double chamber vacuum packaging machines use flat working plates. But for some big products, such as whole frozen durian, whole chicken, lamb legs, etc, a deep cavity-type working plate is necessary to hold the packages.

4. Chamber cover style: There are 2 types of chamber cover –  Flat (about 10 cm high), and Dome type (16 cm high).  We will deliver the double chamber vacuum packaging machines with random chamber cover style if the customer doesn’t specify it.

Dome shape chamber cover about 16 cm high

5. Option: Automatic swing chamber cover. Automatic swing chamber cover is usually used on heavy-duty double chamber vacuum packaging machines, such as LDZ800, and LDZ900, the purpose is to reduce the operator’s burden, because the chamber cover is very heavy.

6. Option: Nitrogen flushing function. For certain food products (bakery, bread, noodles, vegetables, fruits) that need nitrogen to prolong shelf life or for protective purposes, the facility can be pre-installed. Please let us know if you need the function. Please check the below video for reference

7. Another factor to consider is the sealing bar distance, which is the distance of the 2 sealing bars in 1 vacuum chamber, this factor determines the vacuum pouch length. For example, if the sealing bar distance is 40 cm, it means your vacuum pouch length can be 20 cm, but there are exceptions. For products without oil and liquid like frozen fish, cured meat, etc, they can stack in the chamber, so the pouch length can be longer. For regular models, the sealing bar distance is fixed, please find the data in the below table. But you can ask us to customize the sealing bar distance at extra cost.

Heavy-duty double chamber vacuum packaging machine

Heavy-duty double chamber vacuum packaging machine often refers to vacuum packing machines with sealing bar lengths of 800mm, 850mm, and 900mm. The machine with its larger chamber size delivers maximum productivity for your packaging operations. A powerful vacuum pump with a capacity of at least 200m3/h is recommended for the machine, to make sure quick and quality vacuum. A large air cylinder is installed for the automatic swing of the heavy chamber cover.
