Processed starch can be a tremendous expense for pulp and paper mills. It is necessary for wet-end sizing and wet-end retention systems, and can be used as a surface sizing agent to improve stiffness, brightness, opacity, and printing quality. It can also be used for paper coating and as an adhesive in corrugated board, laminated grades, and other products. 

ProFlow’s Continuous Enzymatic Converter allows mills to use the more cost-effective unprocessed starch in their plant, by continuously converting raw starch directly at the process, which saves money in raw materials and reduces loss of material, compared to batch processes. 

A fully automated continuous enzyme conversion system installed at the paper mill can pay for itself in as little as one year through:

• Eliminating the need for expensive factory-processed starch
• Minimizing variability in makedown and starch solids
• Reducing the hassle surrounding batch storage, such as pH monitoring, temperature monitoring, ongoing agitation, and storage tank cleanliness
• Securing stable size press operation

ProFlow, in partnership with Henan Process Systems BV, makes it possible for pulp and paper mills to use raw starch in their processes, by bringing the starch converting process in-house. This is a cost-effective solution that is used throughout Europe and Asia, and is gaining popularity in the United States. 

ProFlow uses a continuous conversion plug-flow principle that minimizes viscosity fluctuations, resulting in a stable size press operation.
