Abstract
Abstract A drying apparatus for a barn milk pipe line system having a casing divided into a motor compartment and a fan compartment by a partition which supports a motor driven blower unit within the casing. The blower unit has a motor housing positioned within the motor compartment and a fan housing positioned on the opposite side of the partition within the fan compartment. A fan within the fan housing draws drying air into the fan housing and forces it outwardly through the fan compartment and casing outlet pipe to the pipe line without contact between the drying air and the motor.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
197 words
In a milking system for barns including a milk pipe line, drying apparatus for blowing out and drying the pipe line after washing operations comprising: a. a casing having an inlet end, a ventilating end, and outlet means, b. partition means dividing the interior of said casing into a motor compartment in communication with said ventilating end, and a fan compartment in communication with said outlet means, c. a blower unit supported within said casing having a motor positioned within said motor compartment and a fan housing positioned within said fan compartment, said fan housing having an air intake communicating with said casing inlet end and exhaust means communicating with said casing fan compartment, d. fan means within said fan housing for drawing drying air into said fan housing intake and forcing it outwardly through said fan housing exhaust means, fan compartment and casing outlet means to said milk pipe line, e. air seal means between said fan housing and said casing for preventing said drying air from escaping from said fan compartment except through said casing outlet means, f. said partition means engaging said fan housing to prevent contact between said drying air and said motor.
