Semi-automatic traysealer for sealing finished trays STvega Tray Sealer L330/380/410/450V/G

Description

STvega Tray Sealers are designed for hermetically sealed packaging of products in finished trays using modified atmosphere technology. The equipment is available in two versions – series V (with vacuum system) and series G (without vacuum pump). Both solutions create optimal storage conditions, extend the shelf life of products and maintain their attractive appearance without the use of preservatives.

Principle of operation

The operator places the filled trays in a variable matrix, sets parameters on the touchpad and starts the cycle. The mold automatically moves inside the machine, where the inert gas is supplied:

• In the V series models , air is first pumped out of the chamber by a vacuum pump, after which gas is supplied, which provides up to 100% air replacement and maximum shelf life.

• In the G series models , gas is supplied directly to the chamber without a vacuum step, which reduces the packaging cycle by 30%, reduces the cost of equipment and maintenance costs while maintaining high packaging quality (substitution rate up to 99%).

After the modified atmosphere is formed, the roll film seals the trays hermetically. At the end of the cycle, the mold automatically returns to its original position, and the operator can take out the finished products.

Equipment advantages

• Extended shelf life due to efficient oxygen substitution (up to 99–100%).

• High cycle speed (especially in the G series without a vacuum stage).

• Economical use of gas due to precise supply control.

• Touch control panel for easy parameter adjustment.

• Automatic movement and return of the form reduces the time of operation.

• AISI 304 stainless steel design – reliability, corrosion resistance and easy cleaning.

• Compact design and interchangeable matrices for trays of different sizes.
