Handling Processes

Bulb Sizing Machine

Bulb Sizing Machine

Tong is one of the world’s leading manufacturers of quality vegetable sizing equipment, and when it comes to sizing bulbs it is no exception. The most popular method of bulb sizing is by lift roller sizing units. Tong manufactures a wide range of lift roller sizers that offer accurate allium and bulb sizing, sizing bulbs by their width/diameter upon a series of moving sizing rollers.

The bulb sizing rollers are manufactured with a fixed row of under-rollers, and adjustable height top rollers. The gaps between the rollers create the specified grade sizes, which increase as the bulbs pass over the roller bed. Small sized bulbs pass through the lift roller sizer first, and subsequent grades are achieved as they pass over the increasingly spaced rollers. Tong’s market leading lift roller sizers can be manufactured to achieve a wide variety of bulb sizes to suit your specific requirements.

Bulb Dirt Eliminating

Bulb Dirt Eliminating

An important part of the bulb sorting and handling process is effective bulb dirt eliminating, to remove soil and dust from bulbs post-harvest. Tong manufactures a number of bulb dirt eliminators which can be integrated as part of a complete mobile or static bulb handling system. Alternatively, they can be used as a stand-alone machine.

A bulb rod dirt eliminator is one of the most popular bulb dirt eliminating machines, and is built to incorporate a dirt eliminating barrel, featuring a drum comprising of a series of rods. The bulb rod dirt eliminator gently tumbles the bulbs as they pass through the barrel loosening any soil or debris from harvest and effectively removing it.

Tong’s coil dirt eliminator is also a popular bulb dirt eliminating system which allows bulbs to pass over a series of coil shafts, whilst soil and debris falls through the coils and onto a waste bulb conveyor. Coil dirt eliminating of bulbs is a very effective way of removing soil from bulbs. When using an adjustable coil dirt eliminator, the gap between the coils can be set to allow small bulbs to be graded out by the coils.
