Description
STvega Vac Termoformer L320/420/520 series thermoformer is a high-performance automatic equipment for vacuum packaging products into polymer trays, designed for processing meat, fish, cheese, convenience foods and other food products. The machine provides a full cycle of packaging: forming cells from film, loading the product, vacuuming, sealing and batch cutting. The equipment combines precision, stability and flexibility of settings, which allows it to be efficiently integrated into various production processes.
Principle of operation:
The packaging process on a thermoformer begins with the automatic feeding of the bottom roll film, which is moved to the preheating zone. Once the required temperature is reached, the film enters the forming station, where, under the influence of temperature and vacuum, trays or cells of the appropriate shape are formed. Next, these trays are filled with the product.
After the product is loaded, the top film is fed from another roll, superimposed on the lower formed part, and the whole workpiece is moved to the vacuum chamber. In this area, air is removed from the package to the set vacuum level, after which the upper and lower films are hermetically sealed under pressure. If necessary, it is possible to connect a gaseous medium for a modified atmosphere.
Next, the sealed tape of packages passes through a cutting system that makes transverse and longitudinal cuts, forming separate finished packages. The film waste is automatically wound onto the corresponding shaft, and the finished products are delivered to the next stage — packing, cooling or stacking.
Equipment advantages:
- A fully automated packaging cycle can significantly reduce labor costs and increase productivity.
- The touch control panel based on Siemens PLC provides convenient setup and reliable control of the machine.
- The 1.5 mm thick stainless steel body ensures the durability and hygiene of the machine.
