Tolsma-Grisnich shows Potato Storage Innovations at Agritechnica

Vision Control Innovations

The Vision Control is an intelligent storage computer that regulates temperature, relative air humidity and CO₂-content during storage by controlling fans, hatches, stoves and mechanical cooling in an intelligent and effective way.

Two new modules highlight the role of the Vision Control as the hub of the storage facility:

Tolsma App 1.0

Using the new Tolsma App 1.0 you can remotely read the storage computer (temperature, RH, hours of operation, statuses as well as alarms/failures for controlled groups).

Another new feature is the option of controlled change of the main settings via the App.

The unique status overview of the Vision Control is also visible through this new App, making it immediately clear which control actions the Vision Control climate computer has performed, and at what time.

Tolsma-Grisnich MV09 Grading Machine

Grading seed potatoes and table potatoes from the processing industry in an environmentally friendly manner and with great accuracy, Tolsma-Grisnich grading machines can be optimally geared to the specific requirements of each product.

The newly developed MV09 also provides the ideal balance between outstanding accuracy and product-friendly treatment.

There will be live demonstrations of the TG MV09 during the Agritechnica.

Tolsma-Grisnich Sample Analyzer

The Sample Analyzer automates the analysis of samples during the storage or processing of potatoes.

The Sample Analyzer assesses, in an objective manner, the length, size and weight in water (WIW, UWW) of the sample. In terms of storage, the data obtained is useful for the sales process of a batch. The automatic delivery of this information ensures the fast and independent assessment of quality within the processing business.

The Sample Analyzer can be operated as a stand-alone machine or as part of a by-pass line adjacent to the storage or processing line.

There will be live demonstrations of the TG Sample Analyzer during the Agritechnica.

5M Temperature Sensor

This award winning innovative 5 metre-long product sensor has been developed to measure temperature differences at different heights in the bulk-storage system.

Enhanced storage efficiency is achieved thanks to anticipation of the storage strategy, underpinned by improved measurements The cable sensor, featuring 5 measuring points, can be incorporated along the gradient of the bulk storage as the product is being stored.

Condensation in the top layer can be avoided and better assessment of the duration of internal ventilation is also made possible.

TTV HE for High Efficiency Potato Storage

Tolsma-Grisnich develop and manufacture all their fans in-house, including the High Efficiency Fan.

This fan, developed using CFD technology and featuring 6 hubs, delivers excellent performance at a counter pressure of between 100 and 200 Pa, which is why its operation is fully utilised within a box storage system.

The fan can be set to either blowing or suction by means of the climate computer, so various storage methods can be applied.

The EC motor is both dust-proof and splash-proof as well as featuring maintenance-free bearings, which ensures that this is an exceptionally maintenancefriendly fan.

This fan comes as a 90 cm ventilator with a choice of three types of motor (2.2, 3 or 4 kW).
