At a glance: The Huanghai MJ150 is a continuous wet-film coating line for oral dissolving films (ODF) and solvent-based transdermal patches (TDDS) that casts two formulas side by side in one pass and dries them in a gradient hot-air tunnel, at about 30,000 films per hour in Gen I. It is for pharmaceutical and health-product manufacturers moving a formula into commercial production, with a direct scale-up path from the MJ150-RD and MJ150-Lab, from Huanghai Pharmaceutical Instruments (Shanghai, since 1978).

What the Huanghai MJ150 does for your production line

Two formulas, one pass. Stripe coating applies two formulations side by side on one base film, so fixed-dose combinations run in a single pass, with no multi-pass layering and no intermediate drying. Exact ratios per strip are set by adjustable slitting width, and the process is estimated to save 20–30% of raw-material waste compared with multi-pass layering. Gen I coats 3–4 stripes. Huanghai's own design (patent application CN117323228A).
Gentle, uniform drying. The 6 m enclosed hot-air tunnel steps the temperature progressively from hot to mild with even airflow and no contact with the film, so edges stay flat and heat-sensitive APIs are protected. Drying runs from room temperature to 120 °C, configurable per zone, and is about 20–30% more efficient than plate-based ovens; far-infrared heating is optional. The technology was developed by Huanghai's team around Academician Hou Huimin (CN201668734U).
Output that grows with you. Gen I delivers about 30,000 films per hour; Gen II (400 mm casting roll, 9–12 stripes) about 60,000; Gen III (twin tunnel, 18–24 stripes) about 120,000. The generation is chosen at order and is not a field retrofit. Gen I width can also be customized when your volume allows.
One process from R&D to production, inline to packaging. The doctor-blade process and 150 mm substrate width are shared with the MJ150-RD and MJ150-Lab. Film thickness detection, online slitting and rewinding are built in, and the roll feeds the MJ180 cutting and packaging machine downstream.
ODF or transdermal patch (TDDS), set before it is built. Each line is configured for one application. Changing after delivery means Huanghai engineers replacing dedicated parts (about 1–2 weeks), so confirm the application at quotation; if you need both, we will propose the right configuration. An explosion-proof electrical configuration is available for flammable-solvent formulations.
Built for GMP and data integrity. Supports pharmaceutical-, supplement- and food-grade production, with a cGMP-oriented design, imported Siemens PLC, electricals and sensors, and features designed to support 21 CFR Part 11 compliance (audit trail, electronic records, access control).
Delivery and warranty. For the coating machine alone, factory acceptance test (FAT) takes 3 months and site acceptance test (SAT) follows within 1–2 months; a line that also includes cutting and packaging takes 4–6 months. Free 1-year warranty, extendable up to 10 years.

Frequently Asked Questions

What is the output of the MJ150 ODF film coating machine?
The MJ150 comes in three generations. Gen I (default configuration) produces about 30,000 films per hour with a 130 mm casting roll; Gen II about 60,000; Gen III (twin tunnel) about 120,000. The generation is selected at order time and is not field-upgradeable. Contact us to match a generation to your target output.

Can the MJ150 produce both ODF and transdermal patches?
The platform can be built for oral dissolving films or for solvent-based transdermal patches. The application is set before manufacturing, because changing it after delivery means Huanghai engineers replacing dedicated component sets (about 1–2 weeks, plus engineer travel and customs clearance for parts for overseas clients). Treat each delivered line as dedicated to one application; if you need both, tell us at quotation stage and we will propose the right configuration.

Does the MJ150 support 21 CFR Part 11?
It is designed to support 21 CFR Part 11 compliance, with electronic audit trails, operator access control and electronic records, and a cGMP-oriented build. Huanghai provides IQ/OQ documentation; PQ and on-site validation are carried out by the end user (or your local distributor as a value-added service). Contact us for compliance documentation details.

What is the difference between the MJ150 and MJ150-Lab?
The MJ150-Lab is the pilot-scale version of the same platform, at 8,000–10,000 films per hour, for development and small-batch production before commercial scale. It uses the same stripe coating and 150 mm substrate width, so a formulation moves up directly.

Which patents and technology does the MJ150 use?
Multi-formula stripe coating (patent application CN117323228A) applies up to two formulas side by side in one pass. Gradient hot-air drying builds on the drying technology developed by Huanghai's team around Academician Hou Huimin (CN201668734U, 2010), giving a progressive temperature profile for film uniformity and API protection. View our patent portfolio.

Is the MJ150 suitable for heat-sensitive APIs?
Yes. Drying temperature is controlled per zone from room temperature to 120 °C, and the film is dried without contact. Wet coating at ambient temperature followed by gentle drying suits heat-sensitive APIs and complex dispersions better than melt-based processes.

Can the coating width be customized?
Yes. Gen I width can be customized with a factory quotation. Gen II and Gen III are intended for customers whose target output exceeds what a customized Gen I can deliver.

How long is delivery?
For the coating machine alone, factory acceptance test takes 3 months and site acceptance test follows within 1–2 months. A line that also includes cutting and packaging takes 4–6 months.
