BV Dairy Invest in Curtains for Their Clotted Cream

As a widely respected independent manufacturer, BV Dairy is committed
to supplying consistent, top quality products using the latest
manufacturing technology. "We operate an ongoing development
programme for both new products and of existing products and
manufacturing processes so are always keen to find ways to energy
costs" Alan McInnes Technical and Operations Director at BV Dairy.
BV Dairy, one of the country’s leading manufacturers of dairy products,
has taken a major step forward to protect its manufacturing process and
reduce its energy costs with a revolutionary air curtain from Airbloc.
The Airbloc air curtain, which will save the company “significant
amounts of money” is used to reduce heat loss from the doorway of
the dairy’s huge walk in oven. It has been designed to keep hot air from
escaping into the food processing plant where it is vital that food,
predominantly milk based products, are kept chilled.
One of BV Dairy’s top sellers is clotted cream, produced by heating and cooling cream at specific temperatures under controlled conditions. The
cream is cooked to produce the best results. The dairy found that the temperature of the oven varied due to door opening.
“The decision to install an air curtain was taken to reduce the heat loss when product was both put into and removed from a walk in oven,”
commented John Cooper, Engineering Manager at BV Dairy. “As well as keeping the processing room temperature down, it has also given the
operator more confidence with the quality of the cooking procedure by keeping valuable heat in the oven to ensure it is cooked right first
time. We have also seen some savings to steam energy and red oil usage!”
Airbloc’s air curtain - designed to produce a high velocity wall of air, which acts as a natural barrier - ensure that hotter atmospheres, like that of
an oven room, do not penetrate into carefully temperature controlled climates. The high capacity ambient units are positioned over the outside of
BV dairy’s oven doors to prevent escape of hot air. Airbloc’s energy efficient air curtains fully comply with advice from the European Food Safety
Inspection Service and are wrapped in stainless steel, making them easy to wipe clean - essential for a food environment.
The air curtain is easily installed horizontally or vertically along a doorway. This is then controlled from a remote switch box. As well as maintaining
the temperature in processing plants more efficiently than any other method available, Airbloc’s air curtains are proven to reduce energy costs by 
eliminating the need for chilling systems that work harder to regulate temperatures.
BV Dairy monitored the effects of the temperature in the processing room before and after the air curtain was fitted, proving the efficiency of air
curtains with lower more even temperature after.
