ROC Systems is a tobacco curing solution supplier based in Zimbabwe with a well-deserved reputation for excellence.

Our philosophy has been to improve every aspect of the tobacco curing process. In our flagship product (the Super Eco Curer) this is reflected by increased operational efficiency & significant cost reductions. Using different Wet Bulb temperatures on each day of the curing process brings about the optimum conditions for the three basic stages of curing, eliminating fungal barn rot, sponge in lower reaping’s and slate in higher reaping’s. Using the different wet bulb temperature, we determine which enzyme we want to work in the leaf at the different stages this results in a quicker wilt and a quicker colour. 


The benefits of the super ecotunnels include:


Our trolleys have wider tier spacing than the normal trolley — in line with the tobacco handbook. This allows for better trolley loading. Typically you can expect a trolley to hold 180 clips each (starting with 100 leaves on primings, down to 50 leaves on strips.)


Our tunnels incorporate a huge surface area on the heat exchanger to ensure maximum redundancy and low steel temperatures. Our H.E. unit is reversible, so when the hot-end shows signs of ageing, reversing it will extend the lifespan.


Unique to the ecotunnel, the Sunday Bay acts as extra storage if there is over- reaping. Secondly, it provides an extra day of colouring in dry seasons. Moreover, the tunnel can be fed evenly on “off” days with green tobacco, bridging the colouring gap between Saturday’s & Monday’s reaping


We supply two 6m steel decked, 2 wheel trailers with each tunnel. These trailers have a low centre of gravity and carry two trolleys at a time. The rails can easily be removed, leaving you with versatile farm trailers outside of the reaping period.
