Low Maintenance Tablet Coating

Modular Spray Manifold
The biggest challenges in tablet coating are caused by the highly-viscous nature of the coatings. Bearding, for example, is the buildup of dried coating on the nozzle, and it causes many tablet coaters to shut down their operation for cleaning as often as every 10 minutes — a time consuming and expensive production delay.
We’ve engineered several innovative technologies that have allowed our customers to run up to 32 times longer without shutting down for maintenance. Our spray products for tablet coating feature:
- Increased control of drop size and spray pattern
- Setups that reduce nozzle bearding
- Sanitary connections that meet FDA requirements
- Smooth, self-draining surfaces that are easy to clean
- Lightweight materials that are easier to maneuver in and out of the coater
Decrease Maintenance Downtime with an Easy-to-Clean Modular Spray Manifold
The Modular Spray Manifold conceals liquid and air tubes inside FDA-compliant, chemical-resistant mounting blocks, greatly reducing the number of exposed tubes and fittings to connect and clean. It weighs 50% less than comparable manifolds so it’s easier to remove from the coater, and it can be disassembled in less than a minute for quick clean-up. The manifold is available with anti-bearding spray nozzles to significantly reduce coating build-up on the nozzle orifice. If you are currently using 1/4 JAU or 1/4 VMAU spray nozzles, you can easily incorporate the Spray Manifold into your process with setups that match their performance.
VMAU Variable Spray Nozzles Reduce Tablet Defects with Increased Coating Control
VMAU Variable Spray Nozzles feature independent control of liquid, atomizing air and fan air, which allows you to fine-tune spray capacity, droplet size and spray patterns in your tablet coating application. Improved control of the highly-viscous coatings reduces quality problems like uneven coating, sticking and logo in-filling.
Designed for FDA compliance, the sanitary body style contains no internal threads in the liquid chamber, and the optional diaphragm actuator decreases seal failure that typically results from spraying harsh coating materials. The modular body is designed for quick and easy maintenance without tools.

Run Tablet Coaters up to 32 Times Longer with Anti-Bearding Setups
| Anti-Bearding Setups redirect air currents and prevent dried coating from clogging the air cap. They can save hundreds of thousands of dollars annually in labor costs for maintenance, wasted product, and the value of production downtime. With a wide variety of configurations available, you can easily replace your existing air atomizing setups with little to no change in spray performance characteristics. Anti-Bearding setups are compatible with 1/4JAU, VAU and VMAU spray nozzles. |

Reduce Costly Coating Consumption with Automatic Air Atomizing Nozzles
| The 1/4JAU is an air actuated air atomizing nozzle that uses compressed air along with a pressurized or siphoned liquid to produce a wide variety of spray patterns and drop sizes. An internal air cylinder controls on/off operation up to 180 cycles per minute. The fast, pulsed spray reduces overspray and consumption of costly coatings. Model 7310-1/4JAU has a knurled head screw control to permit manual nozzle shut-off without disturbing operation of other nozzles on a manifold. |
