Features
ADVANCED CONTROLS
Fitted with advanced technical controls, each EasyGrade sizing screen has variable speed control for screen agitation and speed, allowing operators to fine-tune the sizing screen’s settings to suit specific requirements and contract demands. The ability to fine-tune the agitation of the sizing screen allows complete control over grading accuracy whilst ensuring gentle handling at all times.
EASYCHANGE SCREEN CHANGING
With the EasyChange function, any sizing screen changes can be carried out with a new level of speed and safety. Unlike standard screen sizing modules, which require screens to be manually changed, the EasyChange function allows screen changing to be carried out mechanically, at the touch of a button. Thanks to a new electrical winding mechanism and a joining bar.
The whole process can be carried out in just five minutes, saving users time. Whilst significantly reducing manual requirements in the process as well as improving health and safety.
LONG TUBER HANDLING
Each EasyGrade screen module is manufactured with a long tuber handling device to ensure the gentlest handling of crop. This roller, or rubber star wheel, is fitted immediately prior to the drive roller and rotates faster than it. Ensuring any longer crop varieties are gently dislodged from the screen before they pass over the end.
EXTENDED EASYGRADE MODULE
Extended EasyGrade screen modules have a 300mm longer grading length giving a total screen length of 1.8m, with two rows of agitators. Tong’s extended sizing screens offer a longer sizing band suitable for higher volumes as well as better separation of tubers in extreme conditions. Particularly when sizing longer tuber varieties, the extra length of the screen and additional agitation helps to improve separation. They also allow for easy spreading of the crop, for more accurate sizing.
INTEGRATED STONE REMOVAL
Tong’s EasyGrade screen module with integral stone and clod remover has been specifically designed to bring together sizing and separating in one process.
Tong’s Stone & Clod EasyGrade innovatively combines agitated screen sizing with a steel bounce roller mounted inside. Effectively sizing crop and subsequently separating stone and clod from the undersized crop. This reduces unnecessary wastage of smaller crop in one simple process. By combining the sizing and separating processes, the Stone & Clod EasyGrade offers significant space savings in comparison with using separate sizing and separating equipment. Offering a compact and efficient solution which allows smaller crop to be easily resold or replanted.
GRADING SAMPLING SYSTEM
The EasyGrade sampling system offers effective grading of vegetable samples, with the standard design featuring four Easy Grade Screen modules configured in a row, each 450mm wide. Tong’s sizing sampling system is driven by two variable speed motors. One to control the sizing screen speed, and the other to control the level of agitation on the screens. With standard EasyGrade screens, sized crop falls through the screens. But instead of being discharged onto a conveyor, crop falls onto a chute that effectively delivers sized crop to crates, trays or boxes.
GENTLE HANDLING GUARANTEED
Steel sizing screens remain Tong’s most popular choice due to their gentle handling, robust, reliable and easily repairable design, as well as the sizing accuracy they offer.
However, rubber screens made of out punched rubber belting are also a popular choice for some growers and it really is a matter of preference. Quieter in operation and exceptionally gentle on crop, the rubber sizing screens are also fitted with a common joining system like the steel screens, allowing one screen to be attached to the other for easy changing.
