Taking Advantage of Energy Saving Benefits of Svegma Recirculating Drier

9812 Svegma Recirculating Drier Pic

With the ability to recirculate drying and cooling air prior to the burner or other heat source, the new Svegma recirculating drier offers the potential for major energy savings. This was the prime reason for the first specification in the UK of the drier by Tim Piper. It will be used on his 4000 acre mixed farm where winter wheat, winter rape, spring barley, linseed, spring beans, forage maize, and herbage seeds and vining peas are produced as just part of the farm’s activities.

Tim’s purchase of the Svegma recirculating drier further underlines his commitment to an energy saving policy for the farm. This has also included the installation of 49.8kw of photovoltaic panels in Autumn 2011. Plans are also in hand for the installation of a biomass boiler to provide energy from either, an air to air or hot water to air, heat exchanger to give a base load of approx 750kw of heat. This will then be topped up with recirculated heat, with gas providing the rest. “We also direct drill 80% of our crops, saving a huge amount of fuel and man hours as well as sequestering a huge amount of carbon,” adds Tim.

The Svegma rerirculating drier was found to be very competitively priced compared with other recirculating driers and further savings are made when it is operated to give a good return on the investment. The plan is to use it when necessary, but mainly for the wheat, rape and barley crops.

The energy savings achievable with the drier are down to a number of factors. Firstly, the required amount of air that needs heating from ambient to operating temperature is decreased. Secondly, the recirculated air needs less heat input to achieve operating temperatures. The result is a calculated energy saving of up to 15% for the user.

The drier can be heated using any technology and/or fuel including standard gas, oil or bio fuel heaters, working either directly or indirectly. Stress on the heater is minimized since it does not need to work at excessively high temperatures. Akron’s RadiClean particle-separating fan technology, with its high particle-separating efficiency, also generates less dust and as there is less chance of particles coming into contact with hot surfaces.

Tim Piper decided to purchase the Svegma drier from BDC Systems because it met his requirements in terms of energy saving technology. He also knew that the sales and technical back-up team at BDC had a good knowledge of the product and the associated machinery needed to accompany it. “BDC gave me the confidence that they would be able to sort out any problems that might arise. I also have a neighbour who has run a Svegma drier for a good many years without any major problems.”
