As a leader in processor equipment, technology and options, Walker Engineered Products designs and fabricates its process vessels to 3A Sanitary Standards. With flexibility of materials, vessel configurations and capacities ranging from 10 to 10,000 gallons, Walker vessels are easy to integrate into any process line, making them the clear choice for even the most challenging applications in the food, dairy, beverage, fine chemicals and personal care industries.


Heat Transfer Technologies
Walker offers various technologies for heat transfer including channel on side wall, dimples on bottom cone and half pipe for high temperature applications in the chemical industry.

Processor Configurations
Available configurations of processors include cone bottom, dish top/bottom, slope bottom, open top or flat top w/ hinged covers and more.

Flexibility of Materials
Our engineers can specify the right stainless steel or other metal options for your applications: 304 stainless; 316; AL6XN more resistant to chlorine attack; alloy 20 for chemical process applications; Hastalloy for pharmaceutical and personal care products.

3-A Sanitary Standards
3-A Sanitary Standards are the gold standard for processor vessels. Walker is committed to designing and manufacturing to these benchmark sanitary standards that certify hygienic equipment design for dairy and food processing equipment.  Walker Engineered Products is the only stainless steel vessel fabricator that has the 3-A authorization symbol for five categories: silos, uninsulated tanks, storage tanks, batch processors, and batch pasteurizers.

Viscosity Ranges

Please refer to the examples of cps viscosity measurements and related food items to get an idea which processors are best suited for which levels of viscosity.

Examples of Common Food Viscosity
Viscosity Range   Product Examples 
0 to 500 cps water, milk, fruit juices, ice cream mix
