Used - Used V-TP Stainless Pregrader

Applications & Use Cases

• Pre-grading of root vegetables such as potatoes, carrots, and onions before washing or further processing.
• Initial separation of oversized or undersized items in fruit processing lines, for example, apples or citrus.
• Sorting of seafood products like mussels or oysters by size prior to packing or cooking.
• Grading of bulk dry goods, such as nuts or pulses, to remove foreign material or achieve uniform sizing.
• Use in waste reduction systems to separate valuable product from unwanted debris in food processing.

Typical Specifications

Typical throughput

For this class of equipment, throughput can typically range from 1 to 5 tonnes per hour, depending on product type and screen configuration.

Power supply

Units of this type commonly require a 3-phase electrical supply, typically 400V, 50Hz, with a motor rating often between 0.75kW and 2.2kW.

Construction material

As indicated by 'Stainless', the product contact parts and frame are typically constructed from food-grade stainless steel, commonly 304 or 316 grade.

Screen type

Vibratory pregraders commonly use interchangeable screens or sieves, which can be perforated plate or wire mesh, to achieve different grading sizes.

Footprint

A V-TP pregrader typically has a compact footprint, often around 1.5m to 2.5m in length and 0.8m to 1.5m in width, excluding infeed/outfeed conveyors.

Suitable feed size

This equipment is generally suitable for products ranging from approximately 10mm up to 150mm in diameter, depending on the specific screen installed.
