TEU-H15 Effervescent Tablet Press Machine
TEU-H15 Effervescent Tablet Press 15 Stations 100kN 25mm Diameter
for Vitamin Effervescent Tablets
Purpose-engineered for the unique demands of effervescent tablet production, the TEU-H15 combines 100 kN heavy-duty compression with
specialized anti-stick tooling and dehumidified zone control.
Effervescent formulations—vitamin C, multivitamin, mineral,
electrolyte—present distinct challenges: large diameters, moisture
sensitivity, high compression forces, and sticking tendency. The
TEU-H15 addresses every one of these challenges in a single
GMP-compliant platform.
Why Effervescent Tablets Demand Specialized Equipment: Effervescent formulations react with atmospheric moisture, causing
sticking, picking, and premature reaction during compression. The
TEU-H15 integrates dehumidified compression environment, anti-stick
CrN-coated tooling, and controlled dwell time to produce clean,
stable effervescent tablets at 65,000 per hour.

Effervescent-Specific Engineering Features
1. Moisture Control System
- Dehumidified Compression Zone: Enclosed tablet press chamber with integrated dehumidifier
connection port maintains relative humidity below 30% RH in the
compression area, preventing premature effervescent reaction
- Sealed Electrical Cabinet: Rear-mounted isolated electrical enclosure with positive-pressure
seal eliminates moisture ingress into sensitive electronics
- Desiccant-Breather Lubrication: Central lubrication system with moisture-absorbing breather
prevents humidity contamination of bearing lubricants
2. Anti-Stick Tooling Technology
- CrN-Coated Punches & Dies: Chromium Nitride (CrN) PVD coating on all punch tips and die bores
reduces sticking tendency by up to 80% compared to uncoated
tooling, critical for hygroscopic effervescent blends
- Polished Die Wall Finish: Ra ≤0.2 μm mirror finish on die bores ensures clean tablet
ejection without wall adhesion
- Tapered Die Design: Slight die bore taper (optional) provides progressive relief for
sticky formulations
3. Optimized Compression for Large Tablets
- 100 kN Main Pressure: Sufficient compression force to achieve target hardness on
large-diameter effervescent tablets (20-25 mm) while maintaining
quick dissolution time
- 12 kN Pre-Compression: Extended de-aeration stage removes entrapped air from bulky
effervescent powder blends, preventing lamination defects
- Adjustable Dwell Time: Variable turret speed control allows optimization of compression
dwell time for different effervescent formulations—slower for
brittle blends, faster for robust ones
- 20 mm Filling Depth: Deep fill capability accommodates the low bulk density typical of
effervescent powder blends containing sodium bicarbonate and citric
acid
4. Production Efficiency & GMP Compliance
- Force Feeder with Gentle Handling: Impeller force feeder optimized for effervescent powder flow
without causing particle segregation or premature reaction
- Zero-Spill Powder Plate: Tight-sealing design contains fine effervescent powder, reducing
material loss and keeping the compression zone clean
- Integrated Dust Extraction: Heavy-duty suction at the compression station captures airborne
fine particles typical of effervescent formulations
- PLC with Effervescent Recipe Library: Pre-configured parameter templates for common effervescent tablet
sizes (20mm, 22mm, 25mm diameter) with adjustable compression
profiles
- Tool-Free Punch Changeover: Rapid punch and die replacement for cleaning between batches,
essential for hygroscopic formulations

Frequently Asked Questions - Effervescent Tablet Production
1. Why does my current tablet press cause sticking with
effervescent formulations?
Effervescent blends containing sodium bicarbonate and
citric/tartaric acid are highly hygroscopic. When exposed to
ambient humidity during compression, surface moisture triggers a
micro-reaction causing the powder to adhere to punch faces. The
TEU-H15 addresses this with three layers of protection:
dehumidified compression chamber, CrN anti-stick tooling coating,
and Ra ≤0.2 μm polished die surfaces. Together these reduce
sticking events by up to 80%.
2. What humidity level is required for effervescent tablet
compression?
For reliable effervescent tablet production, relative humidity in
the compression zone should be maintained below 30% RH, with many
manufacturers targeting 15-25% RH for sensitive formulations. The
TEU-H15 sealed compression chamber connects directly to your
facility dehumidifier or desiccant air dryer to maintain target
humidity. We recommend installing an inline RH sensor for
continuous monitoring.
3. How does the 100 kN pressure affect effervescent tablet
dissolution time?
Compression force directly affects both hardness and dissolution.
Too little force produces friable tablets that crumble in
packaging; too much force over-compresses the tablet, slowing
dissolution to unacceptable levels (target: 2-3 minutes in 200ml
water at 20°C). The TEU-H15 PLC control allows you to dial in the
precise force profile—typically 60-85 kN for standard effervescent
tablets—and save it as a recipe. The 100 kN maximum ensures you
have headroom for larger diameter tablets requiring higher
compaction.
4. What is the largest effervescent tablet diameter the TEU-H15 can
produce?
The TEU-H15 with EUD tooling accommodates round effervescent
tablets up to 25 mm diameter and 10 mm thickness. This covers
virtually all commercial effervescent tablet sizes on the market.
For reference: standard Vitamin C 1000mg tablets are typically 25
mm, and most electrolyte tablets range from 20-25 mm.
5. How do I prevent lamination (splitting) in effervescent tablets?
Lamination in effervescent tablets is usually caused by entrapped
air or inadequate binding. The TEU-H15 addresses this with: (1) 12
kN pre-compression stage that progressively expels air before the
main compression event; (2) adjustable filling depth up to 20 mm
ensuring consistent die fill; (3) dual-impeller force feeder
providing uniform powder density into each die; (4) extended dwell
time capability via variable speed control for formulations
requiring longer compression cycles.
6. Can the TEU-H15 switch between effervescent and standard tablet
production?
Yes. The TEU-H15 is a versatile platform. By changing the
punch-and-die set and loading the appropriate PLC recipe, you can
switch between effervescent tablets on the same machine. We
recommend dedicated tooling sets for each product type to prevent
cross-contamination and maintain anti-stick coating integrity.
7. What maintenance is required for the anti-stick CrN coating?
CrN (Chromium Nitride) PVD coating is extremely durable with a
hardness of approximately 1,800 HV. Under normal effervescent
production conditions, coated punches typically last 3-5 million
cycles before re-coating is needed. Cleaning should use soft cloths
and approved solvents—never abrasive pads or metal scrapers which
can damage the coating. Visual inspection for coating wear is
recommended during each batch changeover.
8. Does the TEU-H15 come with a dehumidifier included?
The TEU-H15 includes the sealed compression chamber with
dehumidifier connection port and integrated RH monitoring point.
The dehumidifier unit itself is typically sourced locally by the
customer to match their facility's specific requirements, as
capacity needs vary based on local climate, production volume, and
target humidity level. We can recommend compatible industrial
dehumidifier specifications upon order.
