Tobacco Curing Tunnels

Tobacco Curing Tunnels for Efficient Tobacco Curing

Looking for an efficient and reliable solution for tobacco curing? Tobacco curing tunnels have become a highly trusted method in the agricultural industry, particularly for operations looking to maximise the quality and consistency of their cured tobacco. Known for their precision and efficiency, these tunnels are a staple for both small and large-scale tobacco producers.

At Roc Systems, we specialise in designing, manufacturing, and installing custom tobacco curing tunnels tailored to your unique requirements. With a range of capacities and configurations, we provide flexible solutions that optimise your curing process.

Why Choose Tobacco Curing Tunnel?

Consistency: The controlled environment of a curing tunnel ensures uniform drying, reducing variability in the quality of the cured tobacco.
Speed: The automated process can significantly reduce the curing time compared to traditional methods, which may take several weeks to complete.
Efficiency: The use of mechanisation and automation reduces the need for manual labour, lowering overall production costs.
Quality: The precise control over the curing process helps in developing specific flavours and characteristics in the tobacco, improving its overall quality.
Reduced Losses: Controlled conditions minimise the risk of spoilage due to mould or over-drying, which can often be an issue in traditional air and sun-curing methods.

Unique Trolleys

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 between 7,500 to 9,000 leaves depending on the leaf size.

Heat Exhangers

Our tunnels incorporate a large 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.

Practical Trailers

We supply 6m steel decked, 2 wheel trailers with each tunnel (2 or 3 depending on the tunnel size). They have a low centre of gravity and carry 2 trolleys at a time. The rails can easily be removed, leaving you with a versatile farm trailer outside of the reaping period.
