Filed:

Oct 13, 2001

Appl. No.:

09/976745

Inventors:

Janet F. Dahl - Oshkosh WI
Dennis L. Edison - Fall Creek WI
Paul E. Fowler - Oshkosh WI
Michael R. Stettler - Oshkosh WI

Assignee:

Pro Chemicals, LLC
Westfalia-Surge, Inc.

International Classification:

A01J 704

US Classification:

119 1447, 119670, 119673

Abstract:

An apparatus for producing a foam surfactant suitable for a bovine teat dip having a compressor for air pressurization of a surfactant solution containing a germicide, disinfectant, biocide, etc. , wherein the air-surfactant mixture is passed through a flow or line mixer to a foam holding cup adjacent the teat are, and wherein the mixture is expanding in the holding cup to produce an adherent surfactant foam product with reduced run off, which both protects and reduces infection of the teat and surrounding udder area.

International Classification:

A01J007/04

US Classification:

119 1447, 119670

Abstract:

A method for producing a foamed bovine teat dip is provided. This method may include providing a teat cup configured to surround a bovine teat wherein the teat cup may have an open end sized to accept a bovine teat. This method may also include providing a source of teat dip remote from the teat cup, advancing teat dip from the source of teat dip towards the teat cup, providing a source of compressed fluid remote from the teat cup, sending compressed fluid from the source of compressed fluid towards the teat cup and creating a foam by mixing compressed fluid from the source of compressed fluid with teat dip. Milking the bovine may shortly follow this foaming method.

Appl. No.:

11/122074

Inventors:

Janet F. Dahl - Oshkosh WI, US
Dennis L. Edison - Fall Creek WI, US
Paul E. Fowler - Oshkosh WI, US
Michael R. Stettler - Oshkosh WI, US

International Classification:

A01J 7/04

US Classification:

119 1447, 119670

Abstract:

A method of reducing infection of a bovine teat is described. This method may include providing a surfactant for reducing infection of a bovine teat, creating a foam with a mixture of surfactant and compressed gas, extracting milk from the teat of a bovine, and, following cessation of milking the teat, placing the foamed surfactant on the teat from which milk was extracted. In some instances the foamed surfactant may form a bead at an end of the teat. The method may further include using a compressor to compress the gas, leaving the foam on the teat for more than one minute, and using a hand-held teat cup that can massage the teat as the foam is applied.
