Retort and Side Sealer

Retort Sealer is flexible packing systems is the most acceptable form of food preservation. It represents a unique combination of package, process and product technology with potential economic benefits. Traditionally, tin containers have contributed to a large extent in building the confidence in processed foods. The increasing awareness and aversion to accept other methods of food preservation, irradiation and the like, have created a vast scope for retort processing of foods.

A number of different virgin, multiplayer and co-extruded packaging materials such as polypropylene nylon, polyester cast polypropylene, and polyester aluminium foil cast polypropylene have been evaluated for their mechanical strength to withstand retort conditions at temperature up to 135 Degree C, optimum barrier properties, compatibility with the food products and required a shelf life of 12 months under ambient conditions. DRDO has developed various vegetarian and non-vegetarian food for the services. Some of the products include sooji halwa, upma, channa curry, chicken curry, mutton curry, fish curry, vegetable pulav, chicken pulav, potato-peas curry, mushroom curry and much more. The technology for retort pouch processing of food has been transferred to 17 firms. Some of them are already supplying processes food to armed forces. It is also being exported to the developed countries to cater to the food requirements of an ethnic population from Indian sub-continent.

Side Sealer QS 5545 SSA is ideal for high speed, providing excellent performance. The complete system consists of a fully automatic side-sealing machine and a separate heat shrink tunnel. A speed of the system is up to 20 to 30 packs per minute depending on the product size and film. The machine is fully automatic and an operator is only required for loading packets, monitoring and film changing. Sevana's fully automatic side-sealer QS 5545 SSA uses center folded Polyolefin film. In this machine, a conveyor feeds the product into the film. 

The side sealing is continuous. The machine measures the length of the product using sensor and the sealing jaws operate automatically to perform sealing.After the bag is sealed, it is automatically conveyed into a heat shrink tunnel where film shrinking takes place and the skin tight wrap is produced. The film which is trimmed off during the packaging process is automatically wound up on a waste film take-up reel.

Sevana's fully automatic side-sealer QS 5545 SSA has a microprocessor-based user interface and has a PLC-based back-end. Sevana's machines have added features to preset programs, error display, total count, day count, count of damaged packs etc.
