The case study on chocolate production demonstrates how HPS technology helps a US manufacturer of baking and snack products, Log House Foods, increase yields, reduce waste and improve lot control.

Product recovery (commonly known as ‘pigging’) is in wide use in the process industries. It’s found in everything from food and beverage production, chocolate and confectionery, household goods, cosmetics, paint manufacture and even pet food. That’s because it’s one of the most effective ways companies that process liquids or wet product can increase yields, reduce waste, speed up changeover times and prevent cross-contamination.

The new HPS case study looks at pigging systems recently implemented at a new Log House Foods production facility in Plymouth, Minnesota, USA.

Dennis Stewart, VP Technology Solutions of HPS commented, “we have extensive experience providing pigging systems for companies in the confectionery industry. It was a pleasure to work with Log House on this new implementation because they understood straight away the benefits that pigging would deliver to them”.

The wide variety of benefits provided by pigging systems help improve productivity, efficiency, profits and environmental sustainability.

Pigging uses a special flexible projectile to recover residual liquids from process pipelines. When products being processed are changed over, there’s always product remaining in the pipeline. So, instead of disposing of it, pigging enables the recovered product to continue to be processed, used, packaged or sold.

Log House Foods approached HPS to discuss using pigging to maximise product yield and increase plant capacity while reducing changeover and cleaning downtime.

Dennis continued, “the results Log House are getting from the systems have been great. As well as increasing yields and efficiency, these systems are also decreasing changeover times as well as labour costs”.

Log House Foods is a leading manufacturer of confectioner’s candy coatings, baked products, baking chips, and coconut products. HPS designed, supplied and implemented five fully-automatic single-pig tank select pigging systems for the company.

The pigging systems prevent significant amounts of product standing in the pipelines, which improves lot control and keeps waste to a minimum. Pigging also reduces the need to flush additional product through the lines, which saves product and also minimises cross-contamination risks during changeovers.

What’s more, pigging also decreases changeover times, as well as saving the company resources and labour costs. Using pigging therefore helps Log House Foods towards their environmental sustainability goals.

Dennis concludes, “We expect the pigging systems to quickly provide great return on investment for Log House Foods”.
