Glue Kitchen Setup Guide: Adhesive Preparation Systems for Corrugating Plants
Complete guide to setting up a glue kitchen for corrugated board production, covering equipment, adhesive preparation, storage, and quality control procedures.
The glue kitchen is the adhesive preparation area in every corrugated board factory. Proper glue kitchen design and operation directly affects board quality, production efficiency, and adhesive costs. This guide covers everything needed for a well-functioning glue kitchen.
What is a Glue Kitchen?
The glue kitchen (also called the starch kitchen or adhesive preparation room) is where corrugated adhesive is mixed, cooked, and held before being pumped to the corrugating line. It is the supply heart of the bonding system.
Glue Kitchen Equipment
Mixing Tank / Mixer
Primary vessel where adhesive ingredients are combined
Capacity: 200-2000 liters depending on production volume
Agitator for thorough mixing
Jacketed for heating (steam or electric)
Stainless steel construction preferred
Cooking System
Traditional Starch Adhesive
Steam-jacketed mixer heats adhesive to gelatinization temperature (58-62°C)
Batch cooking time: 15-30 minutes
Requires steam supply from boiler
Instant-Setting Adhesive (Xuegong)
No cooking required — mix starch and powder with water
Preparation time: 15-20 minutes
Room temperature operation
No steam boiler needed
Storage Tanks
Hold prepared adhesive before pumping to line
Insulated to maintain temperature
Agitated to prevent settling and skin formation
Capacity: 2-4 hours of production supply
Multiple tanks allow continuous supply during batch preparation
Transfer Pumps
Positive displacement pumps deliver adhesive to corrugating line
Flow rate matched to production consumption
Strainers remove lumps and undissolved particles
Backup pump essential for uninterrupted production
Piping System
Stainless steel or PVC piping to corrugating line
Insulated pipes maintain adhesive temperature
Circulation loop prevents settling in pipes
Quick-connect fittings for easy cleaning
Glue Kitchen Layout
Recommended Layout
Located adjacent to corrugating line (minimize pipe run)
Separate room or enclosed area for cleanliness
Floor drainage for spill cleanup
Ventilation for steam and moisture control
Raw material storage nearby (starch, adhesive powder)
Quality testing area with Stein-Hall cup and thermometer
Space Requirements
Small plant (1-2 tons/day adhesive): 20-30 m²
Medium plant (3-5 tons/day): 30-50 m²
Large plant (5+ tons/day): 50-80 m²
Adhesive Preparation Procedures
Traditional Starch Glue Batch
1. Add water to mixer (60-70% of batch volume)
2. Start agitator, add caustic soda solution (if alkali-based)
3. Add starch gradually while mixing
4. Add borax solution for gel control
5. Heat to gelatinization temperature (58-62°C)
6. Hold at temperature for 10-15 minutes
7. Cool to operating temperature (25-35°C)
8. Transfer to storage tank
9. Test viscosity with Stein-Hall cup
Xuegong Easy Glue Powder Batch
1. Add water to mixer (required amount per formula)
2. Start agitator, add starch
3. Add Xuegong adhesive powder
4. Mix for 15-20 minutes at room temperature
5. No additives needed: no caustic soda, borax, defoamer, or crosslinker
6. Transfer to storage tank
7. Test viscosity — ready to use
Quality Control
Essential Tests (Every Batch)
Viscosity: Stein-Hall cup measurement (30-60 seconds typical)
Temperature: Operating temperature check
Gel temperature: For traditional adhesives (58-62°C)
pH: 6.5-7.5 for neutral/alkali-free adhesives
Visual inspection: No lumps, consistent color and texture
Testing Frequency
Every batch before transferring to storage
Every 30-60 minutes during production (viscosity check)
After any formula or starch source change
Common Problems
Viscosity Too High
Overcooked, too much starch, insufficient water
Fix: Add water, reduce starch ratio, check cooking temperature
Viscosity Too Low
Undercooked, insufficient starch, too much water
Fix: Add starch, extend cooking time, reduce water
Adhesive Skin Formation
Surface drying in storage tank
Fix: Maintain agitation, cover tank, control temperature
Inconsistent Bond Quality
Viscosity variation between batches
Fix: Standardize preparation procedure, control starch quality
Glue Kitchen for Boiler-Free Lines
Xuegong boiler-free corrugating lines simplify glue kitchen requirements
No steam connection needed
Room temperature adhesive preparation
Easy Glue powder — just starch and water
Reduced equipment investment (no steam jacket required)
Faster batch preparation (15-20 minutes vs. 30-45 minutes)
Lower energy costs for adhesive preparation
Cost Optimization
Use adhesive powder to reduce starch consumption
Recirculate unused adhesive back to storage (within working life)
Match batch size to consumption rate (minimize waste)
Monitor starch price and adjust formulations for cost
Regular equipment cleaning prevents adhesive waste from contamination
