ECS Partnered with Southwest Bakery on a Batch System Upgrade
Southwest Baking collaborated with ECS Solutions Inc., a Recognized System Integrator in the Rockwell Automation PartnerNetwork™ program, to help design and implement a replacement for the limited legacy system.
After assessing a number of vendors, Southwest Baking and ECS Solutions chose to standardize on a flexible batch recipe management system using FactoryTalk® Batch software from Rockwell Automation (Figure 1). The company upgraded its control system to Allen-Bradley® ControlLogix®controllers with an advanced HMI interface and process historian.
Southwest Baking wanted a reliable system with local support to help increase batch consistency across the facility. The company not only achieved this goal but exceeded it.
Since implementing the new batch solution, Southwest Baking increased production by 5% — approximately 10 lb. of dough per minute and an additional 400,000 cases of bread per year.
In addition, the company reduced its cycle time by more than 20%, meaning it can run more batches in the same time frame. Additionally, Southwest Baking has reduced downtime from an average of one hour of downtime per event to a couple of minutes of downtime per event.

ECS Solutions is proud to focus on Batch Manufacturing. Assembling a team of experts, headed by industry expert, John Parraga, ECS is positioned to successfully tackle our clients’/prospects’ toughest problems. We are more than a capable bidder, we are a valued consultant for our clients.
Throughout our journey, we will keep you posted on our progress, new members added to the team and the latest in industry news. Today we bring you our team leader’s thoughts on some batch practices that will become more common in the future:
- Batch Processes that are executed manually will follow procedures that are guided and tracked with portable electronic work instructions; electronic work instructions better report the activities the operators are performing, this data can be used to pinpoint opportunities for improvement and justify investments in process automation.
- Being able to demonstrate in an expeditious manner how products have been manufactured is becoming more important in many industries, this is driving plants to use systems that allow to clearly specify how the products need to be made, enforce their execution throughout the process steps and capture the data to easily demonstrate how the product was manufactured.
- Material Properties and Process diagnostics will be commonly used to dynamically adjust the formulation of active batches without requiring human intervention. (S88 control recipes)
- Some of the existent Batch processes may be converted into continuous processes. This will require a high degree of automation and a clear understanding of the process dynamics and the materials.
- Due to the total cost of ownership and the lack of engineering resources, manufacturers will rely more on OEM vendors to provide the automation required to operate their offerings as well as interface with other OEM equipment.
S88 Builder is a model-based process control system used specifically for equipment control in a batch or continuous process control system. Based on best practices and 40 years of experience, ECS developed S88 Builder to be one common application for controlling any process cell. The model provides an extreme level of both consistency and flexibility for equipment control throughout a process. The consistent model optimizes your process control system for top performance and quality, which lowers production costs and increases equipment availability.
Process manufacturing continues to improve, some improvements come from the implementation of new technologies others improve are motivated by economic or regulatory pressures. ECS Solutions looks forward to expanding our team and working with our clients to ready them for the future of batch manufacturing.
Modern Batch Platform Prepares Bread Maker for Growth
ECS Solutions was featured in Automation World for the work they did with high-volume food producer Southwest Baking. They upgraded their batch process and control platform, based on ISA-88, and prepared for growth with this flexible automation platform.
Southwest Baking brought in ECS Solutions for the system integration and helped design the new batch process platform based on ISA-88 standards, providing more decision-making capabilities to the plant-floor operators. “The upgrade to ISA-88 was done in two stages and completely changed our HMI setup,” Wroblewski says. “We now gave the operator full control of the batch system. They can see what is wrong and resolve issues without calling engineering to fix the situation.”

The Value Of A Truly Modular “Clean In Place” System
Improving overall manufacturing process efficiency is not limited to the tasks and methods used to make the products; important opportunities also exist in the clean in place process (CIP). CIP is a factor that directly impacts the utilization of the plant equipment, as well as the unit cost and quality. A modular CIP system fosters more innovation by providing the process owner the ability to pilot solutions with minimal effort. A properly designed CIP system will not only allow the owner to optimize the execution of the cleaning procedures, but it will also reduce the costs associated with cleaning solutions, water and energy.
Typically, CIP systems are commissioned and their procedures are seldom changed. This is due in part to the rigid logic that provide the process owners very little flexibility to improve the procedures, programs are created to perform tasks such as the pre-rinse, detergent(s) wash, and a final rinse, etc. The process owners find themselves limited to changing recipe values (parameters) and are not given the flexibility to optimize the procedures. If a change needs to be made it may require the intervention of an engineering group to gather requirements, make and test the changes, then release these changes to the process owners. Often, improvements don’t happen because of the time and resources required to make such changes.
The key to allowing the plant to improve the cleaning process is to provide a truly modular CIP system that allows the process owner to configure procedures based on the capabilities of the equipment instead of coded routines.
ISA S88 provides guidelines for the design and specifications of batch control systems. The capabilities of the equipment are exposed to the recipe authors and these capabilities are captured in what is defined as the equipment model. These capabilities are then programed as sub routines (Phases) that can be called upon to be executed at any time.
A procedural model (Recipe) provides the recipe author the granularity that allows the author to define tasks to be performed as well as their triggering conditions. This recipe authoring flexibility empowers the process owners to quickly author new procedures that reflect the current best approach, these can be tested without requiring programing and revalidation of code.
Given the mathematical capabilities of modern automation controllers it is also possible to write equations that can be integrated over time to provide a cumulative cleaning factor, such concept is used for steam sterilization cycles (“F-sub-zero”). This method can be used to dynamically determine when the cleaning cycle is complete without having to follow the traditional method, a direct benefit should be the reduction of time, materials and energy required.
*A major food manufacturer initially reduced their total clean in place time by eight hours per week—creating far more efficiency.
Important opportunities to improve the overall manufacturing process efficiency exist in the clean in place process automation, key to this is a well-defined ISA S88 Equipment Model that provides a modular and flexible solution to the process owners.
