One of the supplemental processes to bread and roll baking is steaming in the ovens. Historically, this has been more of an art than a science and over the years techniques for using steam in the baking process have been passed on from baker to baker.

Why Steam?

Steam is generally used by the baker to provide a glossy surface to the crust and to avoid cracking the crust during the bake.

Important quality considerations for the baker, gloss and cracking are contingent on ingredients and recipe used combined with effective oven operation balanced with appropriate amounts and consistency of steam.

Types of Steam:

Bakers refer to steam used in the bakery in a wide variety of ways including – wet, dry, soft, hard and more. There are, however, two distinctly different steams produced in boilers:

  • Dry Saturated Steam – steam at the temperature of the boiling point of water corresponding to its pressure (212°F @ 0 psig; 240°F @ 10 psig) and does not contain water held in suspension mechanically.
  • Super Heated Steam – steam heated to a temperature higher than the boiling point corresponding to its pressure (250°F steam @ 10 psig equals a 240°F boiling point plus 10°F of superheat). Super heated steam can not exist in contact with water, nor contain water and resembles a perfect gas.

Founded in 1949 by Joseph M. Day P.E., the roots of the company are in the baking industry. Mr. Day gained extensive background in the baking industry through education at the Siebel Institute of Technology in Chicago (forerunner of AIB) and as a project engineer with Baker Perkins (Saginaw, Michigan) and chief engineer with AMF’s, Oven Division locate then in New Haven, CT.

As with most entrepreneurs, this knowledge and experience formed the basis of the company. From this foundation Banner-Day grew as a specialist in automatic gas and oil combustion and control systems, focused primarily in bakery applications. In the late 1970s, Banner-Day developed the application of solid-state ignition/flame rectification modules on direct-fired gas ovens. This work resulted in what is known today as "direct spark ignition" or DSI. DSI systems are the root of all modern day oven automation systems and are required by today’s regulations and codes. With this experience and history Banner-Day is the industry leader in application of DSI systems and fully automated oven control systems for bakery ovens.

The Banner-Day team is focused on the needs of the baker, continually doing research and development work to improve oven performance, flexibility and safety to enhance product quality while reducing operational costs.

Engineering, Design & Project Management

Banner-Day’s commitment to process evaluation and project scope development is fundamental to successful project outcomes that meet your requirements. Key to this process is working with you to identify your needs, critical issues and challenges. After a thorough assessment is completed, Banner-Day’s engineering and design team develops customized solutions and a proposed detailed scope of work for your review and approval. The approved scope of work then forms the basis for a project which is then managed by Banner-Day. Each Banner-Day project has a team leader that is responsible for all facets of the project and meeting agreed upon project milestones.

Turnkey Projects & Installations

Banner-Day provides complete resources for turnkey projects, start to finish. Design/build projects include mechanical and electrical installation and supervision, startup, debug, training and on going support.

Trustworthy engineering and design combined with Banner-Day's experienced team of internal and external resources make installations an easy reality. The Banner-Day team brings years of bakery installation experience with critical skills in thermal, combustion, mechanical and electrical disciplines.

Rebuilds, Repairs & Upgrades

Banner-Day is a valuable resource, offering more than a retrofit or support for the OEM installation. Banner-Day's experience can be applied to more focused needs for you as well. Often you have limited resources available to deal with many of the more routine day-to-day issues like rebuilds, repairs or minor upgrades. The experienced Banner-Day team welcomes the opportunity to work with you to promptly and efficiently support these critically important, more regular activities. An example of the typical work that is done is to recondition existing indirect fired burners. This is only one example of many.


Bakers have seen increased demands on their ovens for flexibility, reliability and safety. The ovens in service today in many cases have been in place for years and do not support the current product, production, safety and environmental demands. Banner-Day has a successful history with custom designs and retrofits to industry standard ovens like Reed, Peterson, Baker-Perkins (732, 935, 960, 970, 980) and more.


Over our history, Banner-Day has directly and indirectly developed strong relationships with leading oven manufacturers throughout the world. Key leaders are Baker Thermal, Baker-Perkins and AMF. These oven manufacturers all have integrated Banner-Day controls into their ovens. This enabled them, and ultimately their customer, to have the world's leading control system managing their oven production. Often times the baker has worked closely with Banner-Day on how to improve their baking capabilities, and when the decision is made to install a new oven, the customer requests that Banner-Day collaborate with the oven supplier to incorporate the Banner-Day system.

Used Oven Upgrades

Banner-Day is uniquely qualified to recondition used ovens. We have the capability and contacts to either execute this for you directly or introduce you to a third party that can provide you with the used oven you want and need. This choice may be a good option when you are working with a tight budget and timeline

Start-Up & Commissioning

Installation is not complete until start-up and commissioning are finalized. Banner-Day personnel are there throughout to ensure everything goes smoothly. Final process adjustments are made and system documentation is finalized.


Banner-Day believes in and is committed to training. Effective sustainable training is critical to a successful project outcome and achieving a project’s ROI over its useful life. Banner-Day will work with you to develop a comprehensive training program at project implementation and for your ongoing system training needs. We regularly work with bakers to conduct first hand in plant training for operations, maintenance and engineering. This can be done on a short or long term basis as is needed by the baker.

Oven Inspections


Included in the complexity of operating a bakery is the ever vigilant need for safety. In addition to the basic concerns of the baker, there are legal requirements to meet government standards. This typically falls under OSHA guidelines. Banner-Day offers inspection services with documentation to ensure you are meeting these annual requirements. A few of the key considerations of Banner-Day OSHA inspections include:

  • Combustion air
  • Gas train
  • Purge system
  • Ignition
  • Exhaust blower
  • Safeties
  • And more


In addition to OSHA inspections, Banner-Day also conducts comprehensive mechanical & electrical inspections. These inspections can be particularly important for bakers that have aging ovens or are interested in an independent view of their oven operations. These inspections can be valuable to the baker for maintaining your preventative maintenance programs, identifying specific repair or upgrade needs and potential areas for retrofitting. A few of the bakery operations that are addressed in the inspection are:

  • Main conveyor system
  • Heating system
  • Crown & lining sheets
  • Loader assembly
  • Unloader assembly
