Application:
A converting mill producing a range of specialty coated printing and copier papers, required a steam injection heater for cooking cationic starch slurry, up to 35% solids. The heater serves a dual function. First, water is pre-heated to 140°F and blended with starch powder. Then the starch slurry is pumped back through the heater at a rate of 40 GPM and cooked at 200°F. Depending on the recipe, post dilution is used to obtain final consistency.
Process Conditions:
Slurry and Water Flow Rate: 40 GPM
Inlet Temperature: 50°F
Final Cook Temperature: 200°F
Steam Pressure: 65 PSIG
Water Pressure: 50 PSIG
Required Steam Flow: 2,580 lb/hr
Solution:
A Pick Model 6X25-3BX Heater was selected for this application. Its generous flow-through design imposes negligible pressure drop on the slurry. It provides thorough cooking at a precisely controlled temperature. The low velocity design minimizes mechanical shear of the starch granules, an important factor for most cationic starches.
Features and Benefits:
• Low Pressure Drop
• Precise Temperature Control
• Low Mechanical Shear
• Compact Design
• Non-Plugging
Why Choose Direct Steam Injection for Pulp & Paper Operations?
Pulp and paper manufacturers use direct steam injection to efficiently heat process water, starch, coatings, and other process streams. Pick Heaters provide fast response to changing production demands while delivering precise temperature control and high thermal efficiency. The result is improved process stability, reduced energy consumption, and reliable operation throughout the manufacturing process.
