MULTIVAC has modified its B 625 chamber belt machine to make a sealing height of 0 millimeters (mm) is possible for the automated and highly efficient packaging of large batches of very flat or light products in film pouches.

Perfect for goods such as smoked salmon, whole and filleted fish, sliced cheese and ham, beef carpaccio, and steaks, the B 625 chamber belt machine from MULTIVAC now allows for the packaging of a wide range of flat products even more quickly, easily, and securely than before. Two sealing bars, which are integrated seamlessly into the base plate in the sealing area of the machine, have made it possible to achieve a sealing height of 0 mm.

The new version of the B 625 machine provides greater security and speed in the packaging process because pouch necks lie completely flat during evacuation and sealing. In comparison to the standard sealing height of at least 25 mm, the pouch necks are no longer bent at a sealing height of 0 mm. The transport of product and infeed into the chamber are also significantly more reliable, since interference areas have been eliminated and friction points on the infeed plate reduced to a minimum. Another benefit in terms of pack security is the temperature-controlled impulse sealing (TI), which ensures that a constantly high level of seal quality at lower energy requirement is achieved, even in nonstop mode.

MULTIVAC has also decoupled the automatic infeed conveyor from the packaging process, enabling the chamber belt machine to be loaded automatically, so that an even higher throughput can be achieved with fewer personnel. And even where the loading takes place manually, the use of just one person for loading creates a significant increase in efficiency.

Additionally, through MULTIVAC Hygienic Design™, the B 625 meets the highest hygiene standards. The chamber lid, which can be swung manually and adjusted in any position, makes ergonomic access to the inside of the chamber very easy, as well as facilitating maintenance of the chamber belt machine and saving time on cleaning. This is reflected in reduced downtime for necessary service work. Furthermore, the robust and durable construction of the packaging machine is a further guarantee of high performance and efficiency.

Finally, other features of the compact B 625 are a high degree of product flexibility and a small footprint. A wide range of pouch materials and designs can be run easily and above all very reliably. Depending on the particular requirement, it is possible to individually select different types of vacuum pumps for equipping the machine. If a shrink tank or tunnel together with a drying tunnel are added, this high-output model can be easily expanded into a very efficient shrink packaging line.
