Model "SVW" Silo Storage Tanks

Mueller Model "SVW" silos provide the ultimate in product protection during storage and their vertical design allows maximum product storage in a minimum of space. Mueller is the only silo manufacturer to go to the time and expense to offer a stud-welded, circumferentially banded bottom construction which guarantees against fatigue, and are willing to back it up with an extended warranty. Mueller is also very proud to offer the first patented, fully CIP-able horizontal agitator that meets the requirements of 3A sanitary standard 22 and the USDA Dairy Grading Branch Survey Program. We offer shop fabricated silos through 70,000 gallons or field-erected, USDA-accepted, 3A-approved silos through hundreds of thousands of gallons.

Horizontal Agitation

Mueller's patented, USDA-accepted, horizontal agitator is cleaned in place and complies with 3A sanitary standards for silo-type storage tanks for milk and milk products. The agitator and seal assembly do not require removal from the tank for cleaning as is required for other horizontal agitators currently available. The newly designed agitator is satisfactory for use in plants that are accepted for the USDA Dairy Grading Branch Survey Program.

This design is also capable of fully separating all sealing surfaces for periodic inspection without the need to remove the agitator shaft. For cleaning, simply open the manway door, install the CIP door and attachment assembly, turn on the agitator, and start your CIP cycle. There's no need to loosen or remove the shaft, thus eliminating the confined space entry procedure.

Retrofit Option

Retrofit for patented, USDA-accepted, 3A designed, fully CIP-able horizontal agitator is also available for field installation.
