Tong has the expertise to ensure your crop is handled gently and is sized accurately. Whether you are looking for screen sizing equipment for potatoes, onions, beet or bulbs, the Tong EasyGrade vegetable screen sizing machine is manufactured in a wide range of widths and lengths to suit all requirements.
Tong’s market-leading EasyGrade chain sizing equipment can be built with a choice of steel or rubber sizing screens. Not only that, but Tong also offers the choice of square or hexagonal steel sizing screens to suit the crop you are handling; hexagonal screens are designed to offer better accuracy when sizing onions, due to their shape.
robust & reliable screen sizing
With sizing capabilities ranging from 10 to 100 tons per hour, Tong’s EasyGrade screen modules are built with robust construction, high performance and minimal maintenance in mind. The EasyGrade screen sizer is available in single, twin or triple configurations, as stand-alone sizing modules, or alternatively designed as part of a complete potato, onion and vegetable sizing system.
EasyGrade screen sizing modules are manufactured in widths of 2 ft., 3 ft., 3 ¾ ft., 5 ft., 5 ¾ ft., 6 ½ ft., 7 ¾ ft wide as standard. They are also available in extended or super-extended models, offering a longer sizing band, which makes the screen sizer more suitable for handling high volumes of crop.
Fitted with advanced technical controls, each EasyGrade sizing screen has a variable speed control for screen agitation and speed which can be fine-tuned to suit your specific screen sizing requirements, whilst ensuring gentle handling at all times.
Single EasyGrade Module
Tong’s single EasyGrade screen module is available in a range of standard widths from 2 ft. to 7 ¾ ft. The standard length of the single EasyGrade module is approximately 5ft long with one row of agitators and a 3ft wide side delivery endless self-tracking conveyor, which is slideable and reversible so that sized crop can be delivered to either side of the screen module.
Twin EasyGrade Module
Tong’s twin EasyGrade screen module is available in standard widths from 2 ft. to 7 ¾ ft. The twin module comprises of two 5ft long screen modules, with one row of agitators in each. Each screen also has its own 3ft wide side delivery endless self-tracking conveyor, which is slideable and reversible so that sized crop can be delivered to either side of the screen module. The option of a transfer roller between screen sections and extended screen options are available on twin models.
Triple EasyGrade Module
Tong’s triple EasyGrade screen module is available in standard widths of 2 ft. to 7 ¾ ft. The triple module comprises of three 5ft long screen modules, with one row of agitators in each. Each screen also has its own 900mm wide side delivery endless self-tracking conveyor which is slideable and reversible so that sized crop can be delivered to either side of the screen module. The option of a transfer roller between screen sections and extended screen options are available on the triple models.
Extended EasyGrade Module
Extended EasyGrade screen modules have just under 1 foot longer sizing length giving a total screen length of approximately 6ft, 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. This is particularly useful when sizing longer tuber varieties; the extra length of the screen and additional agitation helps to improve separation whilst spreading crop evenly, for more accurate sizing.
Stone & Clod EasyGrade
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 to effectively size crop and subsequently separate stone and clod from the undersized crop, reducing 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.
Variable speed motors are also a feature of this sizing machine, allowing speed to be controlled according to required throughput and weather conditions. As standard, the machine is fully mobile and can be easily integrated into a new or existing sizing line. The new Stone & Clod EasyGrade can also be manufactured as part of Tong Peal’s market leading sizing machine – The Caretaker. Available in sizes ranging from 4ft to 8ft in width, the unit can handle all crop sizes and is capable of throughputs up to 500 tons per hour.
Sizing Sampling System
The EasyGrade sampling system offers effective sizing of vegetable samples, with the standard design featuring four Easy Grade Screen modules configured in a row, each approximately 1 ½ ft 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. As 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.
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.
Rubber Screen Option
Steel sizing screens remain Tong’s most popular due to their gentle handling, robust and reliable design and the sizing accuracy they offer. However, rubber screens made of out punched rubber belting are also a popular choice. Quieter in operation, the rubber 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.
Tong has taken screen changing to the next level with the launch of a new option on all EasyGrade screen sizing modules. Designed to increase efficiency and minimize downtime for operators, the new and unique EasyChange function can cut switchover times when changing screens by two thirds. Resulting in significantly less downtime for screen changes which allows users to achieve higher outputs and meet customer demands.
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.
