Tolsma-Grisnich Reveals New Storage Projects in Russia and New Zealand

Tolsma-Grisnich recently announced the delivery of a brand-new storage and grading line, designed for one of the biggest potato and grains wholesale production companies in the Bryansk region, in Russia.

The storage and grading line has the capacity to handle over 6.000 tons of seed potatoes. The building of this new seed potato business in Russia began in early 2019, and the completed operation includes storage locations for boxed potatoes, as well as a fully-equipped grading hall.

Four storage facilities have been equipped with the latest QCC 60 and QML 60 compact coolers. Each cell has a capacity of 1,500 tons of boxed potatoes. The QCCs are fitted with a hatch, so that ventilation with outside air is also possible. All QCCs and QMLs are controlled by a Vision Control climate computer.

The grading installation features a roller inspection table, the MV13 grading machine and buffer-bins with integrated box-fillers. The grader contains four sieving decks, which sort out three different sizes of potatoes. The box filler starts automatically after sensing the box in its place. The total hourly infeed capacity is 30 tons of potatoes per hour, and the fully automated process ensures a significant reduction in the amount of labor required.

At the same time, the company revealed the completion of another storage facility in the heart of Rakaia, Timaru, New Zealand. The beneficiary is the Rakaia Hub Ltd, a company that has grown over the last few years to become a successful place for storage and grading.

The storage facility has a 2,100 tons capacity for the cooling of seed and processing potatoes and is climate-controlled. The potatoes are stored in boxes. The Vision Control storage computer saves data such as temperature, relative air humidity and CO2 and ensures the storage is permanently monitored. The units are designed to run in an energy efficient manner, to keep the power bill low.

Both the Quadro Air Mix Unit 60 (QML 60) and the Quadro Compact Cooler are characterized by their high efficiency and easy installation. The QML can be connected to a cooling unit and the QCC achieves different cooling capacities, using the variable control on the compressor.
