    Sanitary Process Design Engineering

    Since 1980, our team of chemical, mechanical and electrical process engineers have designed hundreds of innovative, efficient and sustainable process and utility support solutions for food, beverage and other sanitary applications. Our experienced team of engineers, project managers, and installation crews provide turnkey solutions and exceptional craftsmanship.

    Our efficient process systems allow you to maximize yields and ensure product consistency. Our collaborative design-build process allows the project team to work on different parts of the process in parallel, providing cost-effective engineering and construction, while bringing your process online faster and at a lower cost.

    Our work begins with conceptualization and continues through formal turnover and system acceptance. We partner with our customers to maximize process performance and deliver measurable improvements in yields, quality, efficiency, resource conservation, product safety, and plant sustainability.

    Resource recovery and reuse

    Water and energy are precious resources and a major expense for processors. BMI teams up with equipment manufacturers to treat and reuse water for chilling, steam production and CIP. We install innovative solutions for recovering and reusing energy such as creating biogas for heat production and using waste heat to create steam-generated electricity. These, and other sustainable solutions will positively impact your bottom line.

    Doing something new?

    Trying something which has never been done? We will do more than cheer you on. We will help design, fabricate, test, and install your first of its kind solution. It takes real commitment to turn a new idea into a commercially viable product and it is even more difficult to do it while conserving natural resources. We can help bring your ideas to fruition with our innovative and sustainable solutions.

    Read what the founder of the Sierra Nevada Brewing Company has to say about BMI

    “Sierra Nevada Brewing Co. has had the privilege of working with Tom Barnum and the talented crew at Barnum Mechanical for over 25 years. They were a valuable partner during several major expansions at our Chico, CA brewery, and have worked on a wide range of other projects over the years. Barnum Mechanical also played a significant role in the design and construction of our North Carolina greenfield brewery, from CAD and engineering help during the design phase to mobilizing a large field crew to assist in equipment installation and process piping.

    They bring a high level of knowledge and understanding of food and beverage processing equipment, sanitary process design, and are competent in complex matrix piping and valve technology. Their attention to detail, stellar workmanship and artesian approach to design and installation continues to deliver value long after they have left the jobsite.”
