Blowdown System
The
blowdown system will prompt the operator to start a blowdown after 125 gallons of water is used. Once
a blowdown has commenced, the blowdown actuator will open, allowing the skimmer tube to remove some
of the foamy contaminated water. The blowdown should expel 1.9 gallons per minute. The contaminated
water then travels through the blowdown hose to where it is routed behind the baler pickup. There, the
contaminated water should be safely discarded on the ground. If the supply water level sensor is faulty, the
blowdown system may not function properly and foaming and water carry over may result. A blowdown
can last several minutes. It is important to let the blowdown finish its cycle whenever possible. The length
a blowdown lasts is dependent on the PPM setting. The higher the PPM, the longer the blowdown. It is
recommended to route the rear blowdown hose behind the baler pickup where it will not spray on the baler
tires. Hot blowdown water has been known to cause premature wear on baler tires.
The purpose of the blowdown system is to prevent water from carrying over the steam hoses and into the hay.
It opens the blowdown actuator, which purges contaminated water out of the boiler.
A manual blowdown is performed each day as part of the pre-operation maintenance. The operator should
drain water for 10 seconds out of the bottom of the boiler by opening the boiler drain valve. When the
DewPoint machine has not been running for a while, the contaminants in the water will settle to the bottom of
the boiler. This manual blowdown is a method of getting rid of the contaminants. While operating the machine
while the water is boiling, the contaminants will rise to the top. The surface blowdown that the operator
performs while running the machine removes these contaminants from the surface of the boiling water.
