What You Need To Know About Sauce Packing Machines
How Sauce Type Affects Your Filler
Thin Sauces
Pump or overflow fillers are designed for free-flowing liquids, so they’re suitable for water and other thin-based liquids.
Thick Sauces
Thicker sauces, like honey or jam, require a piston filler. These fillers are better equipped for high-viscosity liquids and potential clumping.
Machines for Bottles & Cans
Bottle Filling Machines
These are automated machines that dispense a particular amount of the sauce into the bottles. They are available in various types, including gravity fillers, pump fillers, piston fillers, and overflow fillers.
The empty bottles will be conveyed into a filling station where they are held and filled with your sauce.
Capping Machines
These machines securely apply caps, lids, or closures to your sauce bottles. They ensure a tight seal, protecting the content from contamination, leaks, and tampering.
Capping machines, also called bottle cappers, may be automated, which increases production speed and accuracy compared to manual methods. Some types are screw-on cappers, plunger cappers, and those designed for specific cap types like ROPP caps or aluminum caps.
Can Seaming Machines
Can-seaming machines are specialized equipment used to hermetically seal the lids on the metal. To ensure a tight, airtight closure, the machines create a double or triple seam between the can body and the lid.
It utilizes rollers to create a hook between the can’s edge and the lid, which is then pressed and tightened to form the seam.
Cup Filling Machine
Machines for Sauce Pouches
VFFS Machines
Vertical form fill and seal (VFFS) machines are automated packing equipment that form, fill, and seal sauce pouches from a roll of film in one continuous process.
The machine unwinds a roll of film, forms it into a pouch shape, fills the sauce into the formed pouch, and seals it shut with heat and pressure. Some VFFS machines will also cut the sealed sauce pouches into individual units.
Premade Bag Pouch Filling Machines
Unlike the VFFS, these machines automatically fill and seal pre-made pouches or sachets. The sauce is measured and dispensed from the machine’s reservoir into the preformed pouches and moved onto the conveyor belt. After which the pouch is sealed airtight by heating the material. Some machines feature nitrogen flushing to displace oxygen and labeling for product information.
Some types are piston filling, form-fill-seal (FFS), and vertical baggers, which fill sauces in 3/4 side bags.
