Paul Mueller Company's vertical silos are optimized for product protection and efficient space usage at your facility. We offer silos from 5,000-70,000 gallons fabricated in house as well as silos through hundreds of thousands of gallons built at your site. Mueller is also proud to offer the first patented, fully CIP-able horizontal agitator that meets USDA standards. A #4 finish that meets 3A sanitary requirements and makes CIP a breeze is also standard. Our responsive customer service team will work with you to provide the silo that best fits your processing needs.

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.
