Semi-Automatic Pulp Manufacturing Line

This pulp manufacturing line produces cellulose pulp from recycled cellulose fiber sources (paper, newspapers, cardboard, etc. ). It presents the characteristic steps of industrial recycled fiber production lines, scaled and adapted to the capacity and pace of a practical work session. Learn about Semi-Automatic Pulp Manufacturing Line price for optimal educational outcomes.. Educational Objectives: Production line sequencing, regulation studies (on/off and/or PID): levels, temperature, chemical dosing by redox, pump studies (progressive cavity and dosing pumps), physical measurements (speed, pressure, temperature, redox), automation.

The line is divided into modules distributed according to the main steps of pulp manufacturing from recycled fibers. Operative Part:

Support functions:

• Modular or assembled welded stainless steel 304L chassis (~5m, configurable in 'I' or 'L' layout, separable for specific room layouts)
• Paper pulp test equipment: precision balance, simple sheet preparation system (agitated reservoir, vacuum chamber, filter grid, vacuum pump), heating plate, durometer, calipers, surface colorimeter
• Process water storage and recycling unit: 2 polyethylene storage tanks, 2 water transfer pumps, 1 filter

Pulping:

• Pulper: 25L stainless steel 304L tank with variable-speed stirring and double-jacket heated by a 6kW unit (max 90°C)
• Pulped pulp transfer pump
• 2 intermediate 30L polyethylene storage tanks

Mechanical treatment (classifying or refining):

• Ensures homogeneity of cellulose fiber lengths to control mechanical properties and appearance
• Classifier: 25L stainless steel 304L tank and 15L stainless steel 304L drum with rotation and recycled water rinsing
• Classified/refined pulp transfer pump

Decantation:

• Cylindroconical acrylic decanter with vortex stirring for ink flotation
• Supernatant withdrawal pump for pulp concentration
• De-inked and concentrated pulp transfer pump

Chemical treatment (bleaching):

• Oxidizes persistent inks from the flotation stage
• 25L stainless steel 304L bleaching tank with variable-speed stirring, double-jacket thermostatically controlled by a 6kW unit (max 90°C)
• Oxidizing agent dosing system and redox potential measurement probe
• In educational settings, only diluted hydrogen peroxide is recommended (not supplied)
• Final pulp transfer pump

Control Part:

• Local control system for all steps via a 9.
