Potato Review

44 POTATO REVIEW SEPTEMBER/OCTOBER 2020 MACHINERY FOR the 2020 season, Grimme’s RH-receiving hoppers series has been extensively revised and equipped with new practical features. A good seal between the transport vehicle and the receiving hopper minimizes the loss of harvested crop and improves the cleanliness and hygiene of the entire storage process. Since transport vehicles have di erent contours in practice, the sealing rubber intake aps must be particularly exible and quickly adaptable. GRIMME has therefore completely revised the design and function of the receiving area to further improve the quick and safe “docking” of the transport vehicles. e lower support strip, which enables easy rearward manoeuvring to the hopper, especially for transport vehicles with a deep underride guard, is able to move to the rear for improved material protection. ree rubber lips are tted to the lateral bunker walls, each of them subdivided into three parts. In this way the rubber lips adapt to any vehicle contour. e rubber intake aps are now ball-bearing mounted. ey are height-adjustable without tools, so that it can be quickly and easily adapted to the di erent heights of transport vehicles. Losses while lling the receiving hopper can now be prevented even more e ectively. e transition from the grading or cleaning rollers onto the cross conveyor is often the limiting factor of a receiving hopper, as the crop can only be fed onto the cross conveyor on one side. With the new VarioFlow, GRIMME o ers an optional available transfer device consisting of two PU spiral rollers with mechanically adjustable height. With this transfer device, more crop can be transferred more evenly to the crop cross conveyor, which signi cantly increases the conveying capacity. e transfer height of the two PU spiral rollers onto the cross conveyor can be in nitely adjusted by means of one spindle each on the left and right side of the machine. is adjustment enables the two PU spiral rollers to mesh together when adjusting between di erent discharge heights, ultimately this leads to increased crop protection. By having a minimum transfer height to the discharging cross conveyor on one side, maximum crop protection is achieved. On the lower side of the conveyor the passage is increased as the rollers are lifted out of the crop ow. At the same time the transfer height remains minimal because the crop is transferred onto other crop on the downstream-side of the conveyor. e result is a signi cant increase in throughput capacity, while maintaining a high level of crop protection. e new lubricator o ers a practical solution for oiling the hopper chain and therefore increases the durability to a maximum. Maintenance and care of the machine is considerably simpli ed for the operator, as manual lubrication of the hopper oor chain is no longer necessary. • Grimme has now taken over the Danish specialist for vegetable technology, ASA-LIFT. Revised and extended receiving hoppers TONG Engineering’s new generation E-TIP box tipper is built upon a patent-pending design which features a crop-retaining lid for the gentlest handling, alongside an energy-e cient all-electric drive system and is now available to growers and processors worldwide. Tong’s Managing Director Edward Tong said what sets the new E-TIP box tipper apart is the way the box is cradled throughout the tipping process, with a conveyor-belt lid. “ is ensures boxes are securely and gently rotated, without any friction or scu ng to crop,” he said. “ e sliding action of the lid ensures gentle transfer of crop from the box to the machine’s forward conveyor, as well as ensuring seamless upward ejection of empty boxes for continuous operation and maximum performance.” e E-TIP box tipper replaces traditional forward pivot-tipping hydraulics with a box-rotating design, powered by Tong’s Blue Inverter Technology all-electric direct-drive motors. e machine requires much less forklift movement than traditional box tippers and can be speci ed to suit a variety of box sizes, depending on requirements.
