Steam Infusion Cooking System for Soups, Sauces and Condiments

PM Fresh produces soups, sauces and condiments across a range of recipes. PPN supplied the complete IOPAK cooking line and built its stainless steel platform, then retrofitted OAL Steam Infusion to increase cooking capacity and protect heat-sensitive products.

1. The Client Brief & Challenge

PM Fresh needed greater output from its cooking line for soups, sauces and condiments. The system had to protect heat-sensitive recipes while meeting a product launch deadline.

  • Slow cooking: Batches took over 120 minutes.
  • Heat-sensitive sauces: Cream-based recipes required protection from burn-on.
  • Existing vessels: Capacity had to increase within the existing facility.
  • Launch deadline: The requested solution window was ten weeks.

2. The Process Plant Network Solution

OAL designed the Steam Infusion system; PPN installed the lances, recipe controls and steam supply. The retrofit covered four IOPAK cookers: two of 1,200 L and two of 600 L.

The cooking line combines load cells, recipe prompts and automatic water dosing. Operators add ingredients against the recipe, with vessel weights tracking each addition. Steam Infusion provides rapid heating, then the jackets maintain temperature. Product can recirculate through emulsifiers to achieve the required texture before transfer to packing.

PPN supplied all machinery for the original cooking line under its IOPAK brand and built the stainless steel platform. The scope included safety gates, pipework, valves, pumps, emulsifiers, load cells and the control panel with recipe control. All four cookers have scraped-surface agitators. Safety grids beneath the lids allow ingredients to be added while restricting access to the agitators, with interlocks that stop the agitators when the grids are lifted. For the later Steam Infusion retrofit, PPN modified the lids and fitted temperature probes and additional steam controls.

New Equipment

  • Two IOPAK 1,200 L jacketed cookers with scraped-surface agitators.
  • Two IOPAK 600 L jacketed cookers with scraped-surface agitators.
  • PPN-built stainless steel platform with safety gates.
  • Pumps and emulsifiers, with connecting pipework and valves.
  • Load cells, control panel and recipe control with automatic water dosing.
  • OAL Steam Infusion cooking lances for four cookers.
  • Additional steam supply pipework, valves and controls.
  • Temperature probes and controls for Steam Infusion.

3. Implementation & Timeline

Original cooking line

PPN supplied the four-vessel IOPAK cooking system with its platform and recipe control.

Review and process design

The producer assessed cooking technologies before selecting Steam Infusion.

Steam Infusion retrofit

PPN fitted Steam Infusion to the installed cookers at the customer’s subsequent request.

Commissioning and launch

OAL supported commissioning and recipe development. The team met the product launch date.

4. Results & Business Impact

  • More capacity: Shorter cooking times allowed more than double the cooking output from the same vessels.
  • Shorter cooking cycles: Cooking times fell by over 50%.
  • Product quality: Quality improved, with no vessel burn-on.
  • Cleaning: Cleaning requirements decreased.
