Coffee Machine in Randburg

We have likewise established a good reputation with the Tea Packers and Coffee Roasters within international Tea and Coffee markets for fine teas and coffees that we export from this region. With the companies good history within the agricultural industry in Africa, we also represent Pinhalense Brazil and Electrostatic Spraying Systems Inc. U.SA for their fine agricultural machinery. This being a full range of processing equipment for the coffee, nut and cocoa farmers and the innovative electrostatic agricultural sprayers that these companies manufacture. From our main Johannesburg office, the company deals directly with coffee farmers, coffee co-operatives, coffee mills and coffee exporters in Central America, South America, Africa and Asia to source coffees for our Southern African, North American, Europ. These tiny droplets are carried deep into the plant canopy in a high-speed air-stream. We are also proud to offer coffee, Tea and Rooibos from Rainforest Allicance Certified TM Farms. The result is more than twice the deposition efïciency of both hydraulic and non-electrostatic airassisted sprayers. Electrical charging causes a natural force of attraction between the spray droplets and the plant, similar to the attraction between items of clothing created by the tumbling of a clothes dryer. The charge on the droplets is small, but the force pulling the spray towards the plant is up to 75 times greater than the force of gravity. Droplets literally reverse direction and move upwards, against gravity, when passing a leaf surface. This remarkable phenomenon by which the spray coats the undersides of the leaves and the backsides of the stems is known as electrostatic wraparound. Spray coverage is the uniformity of spray droplets on plant surfaces. Chemical burn is reduced because chemicals do not accumulate in large single deposits. Low-volume spraying requires 10 to 25 times less water carrier than standard spraying. This is possible because of the uniform droplet size and improved coverage characteristics achieved by the electrostatic sprayer. Above: This is a good example of ESS air assisted electrostatic application of dye, on to the underside of a coffee leaf 400 mm inside and at the bottom of the thick coffee tree canopy. This dye is applied by a side on spray and well illustrates, how the positively charged leaf attracts the negative charged droplets onto its surface. Even when the spray is not directly targeted towards the surface of the leaf and when it is already, protected by the outer canopy of leaves.
