Pill & Candy Coating
Pill coating and candy coating processes use airflow measurement systems at both the inlet and exhaust. Precision monitoring equipment from Air Monitor helps maintain the proper air pressure and temperature to distribute the coating across all products in the batch evenly.
Air Monitor Solutions Can Help You…
Enhance Product Quality
Monitoring air flow helps maintain ideal conditions to avoid twinning, poor adhesion, and uneven enteric coating.Reduce Expensive Waste
Prevent defective batches of high-dollar pharmaceutical pills by carefully monitoring the coating process.Gain Pill Coating Process Efficiency
With precise airflow monitoring, the coating process can be analyzed and tuned for efficiency to scale up production.ACCU-flo High Accuracy Stainless Steel Station
The ACCU-flo/NP combines a precision nozzle with a multi-point, self-averaging Pitot airflow measurement station. It provides high accuracy (±0.5%) flow measurement for process monitoring and control applications with little or no upstream straight run.
The air flow measurement station is available in either Type 316 stainless steel or carbon steel, with a combination of welded and bolted flanges, and can operate up to 900ºF. Applications include quench airflow, product testing, and process development.
LO-flo/SS Stainless Steel Pitot Traverse Probe
This combination air equalizer-straightener and self-averaging Pitot tube traverse station is fabricated entirely of Type 316 stainless steel with all welded construction. It is capable of operating up to 1000ºF.
The probe provides highly accurate measurement of low air volumes of 2 to 2000 CFM for monitoring, indicating, and controlling applications when coupled with ultra-low span electronic differential pressure or flow transmitters (such as the Air Monitor VELTRON II, MASS-tron II, and VELTRON DPT-plus transmitters).
Applications include dust collection systems, quench exhaust, fluidized bed dryers, pill coaters, and rotary drum dryers/coaters.
VOLU-probe SS – Stainless Steel Traverse Probe with Transmitter
These stainless steel flow measuring probes consist of multiple Pitot total and static pressure sensing ports positioned along their lengths to traverse the duct cross-section. The probes average the sensed pressures in their separate internal manifolds and provide velocity pressure measurement accurate to within 2-3% of actual flow.
Applications include quench airflow, fluidized bed dryers/coaters, and rotary drum dryers/coaters.
VELTRON II Transmitter
This ultra-low differential pressure and flow “smart” transmitter has an accuracy of ±0.1% of natural span. The transmitter comes equipped with an automatic zeroing circuit which eliminates all output signal drift due to thermal, electronic, or mechanical effects.
Applications include quench exhaust, fluidized bed dryers/coaters, and rotary drum dryers/coaters.
More About Accurate Airflow Monitoring in Pill Coating
Pharmaceutical companies and makers of vitamins and nutraceuticals have a unique need for accuracy. The U.S. Food and Drug Administration (FDA) Title 21, Subchapter B, Part 175, Subpart C, regulates indirect food additives, including adhesives and components of coatings used in the consumption of food and drugs.
Coating equipment must adhere to these regulations about colorants and other substances used to coat food, candies, and pharmaceuticals. In the case of pill manufacturing, extreme precision is required because of the high dollar value of the powders that are processed in pill coating equipment.
For these applications, Air Monitor equipment such as the VELTRON-II transmitter and the LO-flo/SS pitot traverse probe airflow measurement system can accurately measure airflow into a fluid bed tower with a wide turndown and limited straight pipe runs.
