Bottling linesareproduction linesthat fill a liquid product, often abeverage,intobottleson a large scale.[1]Many prepared foods are also bottled, such as sauces, syrups, marinades, oils and vinegars.[2][3][4][5]

Bottling lines usually include label application equipment, capping operations, date stamps, etc. Quality assurance verification equipemt is often included.

Beer bottling process

Packaging of bottled beer typically involves drawing the product from a holding tank and filling it into bottles in a filling machine (filler), which are then capped, labeled and packed into cases or cartons. Many smallerbreweriessend their bulk beer to large facilities forcontractbottling—though some will bottle by hand. Virtually allbeer bottlesareglass.

The first step in bottling beer isdepalletising,where the empty bottles are removed from the originalpalletpackaging delivered from the manufacturer, so that individual bottles may be handled. The bottles may then be rinsed withfilteredwaterorair,and may havecarbon dioxideinjected into them in attempt to reduce the level ofoxygenwithin the bottle. The bottle then enters a "filler" which fills the bottle with beer and may also inject a small amount ofinert gas(usually carbon dioxide ornitrogen) on top of the beer to disperse the oxygen, as oxygen can ruin the quality of the product viaoxidation.Finally, the bottles go through a "capper", which applies abottle cap,sealing the bottle. A few beers are bottled with acorkandcage.

Next the bottle enters a labelling machine ( "labeller" ) where a label is applied. To ensuretraceabilityof the product, alot number,generally the date and time of bottling, may also be printed on the bottle. The product is then packed into boxes andwarehoused,ready for sale.[6]

Depending on the magnitude of the bottling endeavor, there are many different types of bottling machinery available. Liquid level machines fill bottles so they appear to be filled to the same line on every bottle, while volumetric filling machines fill each bottle with exactly the same amount of liquid. Overflow pressure fillers are the most popular machines with beverage makers, while gravity filling machines are most cost effective. In terms of automation, inline filling machines are most popular, but rotary machines are much faster albeit much more expensive.[7]

Wine bottling process

[edit]

The process for bottlingwineis largely similar to that for bottling beer, exceptwine bottlesdiffer in volumes and shapes. Traditionally, a cork is used to provideclosureto wine bottles. After filling, a bottle travels to a corking machine (corker) where a cork is compressed and pushed into the neck of the bottle. Whilst this is happening, the corkervacuumsthe air out of the bottle to form anegative pressureheadspace.This removes any oxygen from the headspace, which is useful as latent oxygen can ruin the quality of the product viaoxidation.A negative pressure headspace will also counteract pressure caused by thethermal expansionof the wine, preventing the cork from being forced from the bottle.Champagnesandsparkling winesmay further be sealed with amuselet,which ensures the cork will not explode off in transit.Alternative wine closuressuch asscrew capsare available.

Some bottling lines incorporate afill height detectorwhich reject under or over-filled bottles, and also ametal detector.
