Tolsma develops innovative control technology for sorting, washing and packagingunits for companies that process foods such as potatoes, carrots and chips. Itscombined knowledge of agricultural products and electrotechnical units enablesTolsma to make a valuable contribution to the design and implementation ofsorting, washing and traceability projects at sorting and processing companies.
The Quadro air-mix unit is specially designed for box storage. The internal air is mixed with fresh air from outside until the required ventilation temperature has been reached. Expansion of the Quadro air-mix unit with a refrigeration unit is simple. This latter unit comprises an air cooler through which the air is cooled. Several air-mix units can be connected to a common direct or indirect refrigeration unit.
The GCU (Green Cool Unit) is one of the Tolsma's own innovations. Achieving optimal storage efficiency was the goal in developing this direct cooling system, so minimal drying-in and energy saving are crucial. The application of advanced compressor technology in combination with an intelligent control system (developed in-house) has made it possible to achieve the highest possible efficiency for the total storage system. The GCU is available...
The innovative digital Potato Scanner assesses samples of potato crops quickly and without sorting. Ingenious camera system: The Potato Scanner is a mobile system that consists of a feeder hopper, a flat conveyor belt, a casing containing the electronic camera system, and an output hopper. Accurate evaluation of samples: The camera system scans the sample and makes an accurate determination of the numbers of tubers, their sizes (length and diameter)...
For optimum exploitation of any installation’s capacity, product supply must be attuned. What’s more, the product must not be damaged during unloading. Grisnich provides appropriate solutions with a wide range of capacities.
The stone and clod separator can remove stones and clods from a batch of potatoes, onions or other root vegetables with an accuracy of 95%. Because of the advanced sensor technology, a high capacity (15 to 50 tons/hr) can be realised. This machine has definitely made its mark, and is unique in the potato processing business. It can be deployed as a stand-alone unit or as part of a processing line.
Tolsma-Grisnich has developed an intelligent dry soil removal installation for the 24/7 removal of soil, haulm and other inherent non-product elements from agricultural produce. The installation has an hourly output of 80 tons of potatoes and fits in perfectly with the processing line of, for example, a French fries plant. Cleaning capacity, product-friendliness, intelligent control and minimal maintenance requirements are key design elements.
Potatoes and onions almost always have to be sorted according to size as part of their processing. Depending on their use, the determining factor will either be the greatest accuracy or the highest capacity. Grisnich has the perfect solution for both choices.
No matter how ingenious the design and installation of a sorting system, there will always be routes where the product must be transported vertically or horizontally from one place to another. Grisnich’s transport conveyors are tailor-made (width to 160 cm). These product-friendly conveyors are characterised by their stable, durable frame.
