Handling Equipment – Grisnich Storage Bunkers Storage bunkers are used for buffering product in a processing line of tuberous and bulbous crops Storage bunkers are used for buffering product in a processing line of tuberous and bulbous crops. For processing companies it is the perfect solution for creating continuity in a processing line. The storage bunkers offer a various range of possibilities, for both large-scale as well as small-scale storing. If need be, the storage bunkers can also be fitted with advanced refrigeration and ventilation systems. Optimal processing The storage bunkers are developed to create an optimal processing flow of the processing line. Integrated with a grading installation, storage bunkers are being used as buffer with diverse filling and extraction systems. Filling is done using central filling, a moveable filling conveyer or a tilt conveyer, all combined with a fallbreaker. Filling can also be done using a descending conveyer with moveable end, where the end part of the conveyer will be lowered in the bunker. Unloading the storage bunker is done using a valve or a conveyer.Making use of storage bunkers enables high capacity seperation of different sizes and potato varieties. The desired size or variety will be stored in 1 storage bunker. The angle of the funnel is 45°, which ensure an optimal extraction flow. We develop both extraction conveyers as well as discharging valves with various compartments. This makes sure that within any process of the processing line, buffering can be made possible. The advantages: Efficient seperation of size and varietyOptimal fillingVarious storage capacities possible. Box Handling Speed and logistic gains are the decisive factors in achieving the highest possible efficiency in the filling and emptying of boxes. Speed and logistic gains are the decisive factors in achieving the highest possible efficiency in the filling and emptying of boxes.Box fillers and box tippers meet these requirements and can realise a capacity of 80 tons per hour. Both systems can be used as either stand-alone or integrated units. Fully automated box filling The TG Automatic Box filler-18 is capable of stacking, de-stacking and filling empty boxes fully automatically. The filled boxes are stacked and transported by means of a roller conveyor. A capacity of 80 tons per hour can be realised thanks to the uninterrupted filling process. In addition, the TG Automatic Box filler-18 reduces the number of forklift truck movements by 40%. Different filling programmes and conveyor speeds can be set using the handy touch screen control. Box filler for uninterrupted supply The product is fed directly to the TG Automatic Box filler-18 by means of a roller cleaning unit (option). The product is stored in a small intermediate bunker during box changes so that supply can continue without interruption. When filling is resumed, the intermediate bunker is emptied first. The box is tilted and then filled with a minimum drop height so that no cone develops in the centre. Automated box emptying system The automated box emptying system can automatically de-stack and empty filled boxes as well as re-stacking the empty boxes. The modular roller conveyors and (de)-stacking units of the TG Automatic Box Filler-18 can be used for this. The boxes are turned within a bracket frame with transport straps above and below the box. As the box is moved sideways it is gently emptied over a transport conveyor which removes both box and product, so achieving an exceptionally high capacity.

For optimum exploitation of any installation’s capacity, product supply must be attuned. What’s more, the product must not be damaged during unloading. We provide appropriate solutions with a wide range of capacities. Unloading systems We have a suited solution for every way of unloading, for both extraction conveyers, as well as tipping trailers and boxes. The hoppers that we have developed offer various solutions for unloading product, for both back-end tipping and sideways tipping. For unloading from boxes, we have developed dosing bunkers, to suit every need in capacity. The systems advantages: Capacity up to 170 ton/hQuick unloading of productConstant product flowBack and sideways unloading. Fall Breaker The retractable fall breaker (folding chute) is a unique and proven concept for filling lorries, bunkers, boxes and big bags without damaging the product.

It can be used for potatoes, onions, shallots, carrots, etc. Our standard fall breaker is equipped with a hopper, eight fall breaker flaps made of plastic fabric and a hoist motor. The flaps are operated by means of a hoist motor with hoist straps. The retractable fall breaker is characterised by its simplicity and flexibility. Three models The fall breaker is available in three models, VC40, VC60 and VC80. Many options are possible, which means that the fall breaker can be customised to suit the user’s requirements.Benefits:Suited for various sorts of productFlexibility in fall heightEasy to adjust. Double box filler / big bag filler A box filler or big bag filler consists of 2 retractable fall breakers and a support frame The big advantage of this machine is that it can be used for both boxes and big bags. Due to the double function, the logistics process can continue at all times. We offer a box filler that provides more capacity. More capacity and less labour The box filler is fed by a conveyor belt for potatoes or onions. Harvested products are more and more stored in boxes. As a result, batches can be stored separately. This offers a major advantage in the seed potato and table potato sector. In addition, because of the low falling height, the chance of pressure spots is smaller.A box filler improves the logistic efficiency. It ensures that the work runs smoothly and the boxes are well filled. Because boxes do not always have the same size, you can set the height of the box filler. About the double box filler The product sensor ensures the correct position of the fall breaker, so that the falling height is as small as possible. The fall breaker is very product-friendly due to its synthetic cloths. This box filler can be used for potatoes, onions, shallots and carrots.The machine is suitable for various sizes of big bags and boxes. Due to the applied intermediate position switch, this machine can also be used for automatic filling of boxes and big bags. The conveyor belt is enclosed in a belt frame and rests entirely on the carrier rollers. The box filler is controlled via the central control box.
