Tunnel warmers are machines used in the packaging segment of the food and beverage process. The job of a tunnel warmer is to warm bottles and other packages that are relatively cool as compared to the ambient temperature in the bottling plant, especially if the humidity level is moderate to high. In this case, a problem can arise where condensation can accumulate on the package, bottle, etc. which causes difficulty in applying the bottle’s labels.
A tunnel warmer can warm the package or bottle to the proper temperature so that condensation will not re-form after the condensation has been removed and the label will be able to be applied without a problem.
Tunnel warmers are, as the name implies, tunnel shaped structures. They have conveyors running through them, transporting the bottles being warmed. The bottles are subjected to a spray of warm water to raise their temperature and are then dried with a stream of air at the back end of the warmer. The machine should be constructed of stainless steel, with a minimum rating of 304. PRO Engineering machines are made of 304 stainless steel. This feature reduces corrosion from caustic cleaning chemicals that may be used on the bottling line.
Tunnel warmers should be located directly before the labeler in the packaging line. This placement reduces the ability of the bottles to form condensation on them a second time, after the air stream has removed the initial condensation before being labeled.
