Yogurt tray thermoforming filler sealers (FFS) are industrial machines designed to pack yogurt and similar dairy products into thermoformed plastic trays. These machines play a crucial role in the dairy industry, enabling the automated filling and sealing of individual portions of yogurt. Here is how a thermoforming yogurt tray sealer (FFS) filler generally works and what it is for:
Filling and forming function:
Tray Forming: The process begins with forming plastic trays from a sheet of thermoplastic material such as polystyrene (PS) or polypropylene (PP). The trays are heat-molded into the desired shape, which typically includes individual cavities to accommodate the yogurt portions.
Yogurt feeding: Yogurt is fed into the machine from specific storage tanks. It is important that the yogurt is previously pasteurized and refrigerated to maintain quality and safety.
Tray positioning: Thermoformed trays are positioned under filling stations, which are part of the machine.
Filling: While the trays are positioned at the filling stations, the yogurt is dosed and inserted into the trays' individual cavities. This is usually done precisely using dosing pumps or pistons.
Sealing function:
Sealing: After filling, a sheet of sealable plastic film is placed over the trays. The machine applies heat and pressure to hermetically seal the film onto the trays, keeping the yogurt protected from contamination and extending the product's shelf life.
Quality inspection function:
Quality inspection: Filled and sealed trays are frequently subjected to automated inspections to ensure product quality, such as checking seal integrity, dosage consistency, and possible contamination.
Final labeling and packaging function:
Labeling: After sealing, trays can be directed to labeling stations, where labels with product information, expiration date and other details are applied.
Final packaging: Individual trays can be grouped into larger packages, such as boxes, displays, or other types of packaging, as needed, for distribution.
These thermoforming tray sealing (FFS) fillers are essential for the production of yogurts packaged in individual portions. They ensure that the yogurts are properly packaged, sealed and ready for distribution, guaranteeing the quality and integrity of the product until it reaches the end consumer. |
