The Nicomac Coating System (NCS) combines a unique design with advanced coating performance and versatility in the ever-evolving process industry. This system has gained worldwide success in the pharmaceutical and confectionery industries. Below are some important parameters that make Nicomac stand out from the competition:
Equipment Nicomac allows the coating of sugar, organic or water-soluble films in the same machine, as well as the coating of tablets, lollipops, small tablets, granular products, from tiny sugar crystals to large tablets, without changing parts. One of the biggest advantages is that, thanks to the special design of the drum and the "Blow Master" coating drying system, the equipment can operate at 10-15% more than the full capacity of the drum without reducing productivity.
Powder dosing system. Automatic dosing of powders is possible if a blower or electrostatic system is required. The new patented system avoids powder clogging and allows for high process control with high productivity. The powder is fed into the chamber without dispersion. Very high productivity.
Productivity. Whatever your capacity requirements, we have a model to suit your application. The range of models is from lab scale throughput of up to 10 litres, to large production scale up to 2,300 litres. The world's largest pelletising boiler in the pharmaceutical industry.
The patented "Blow Master" coating drying system is a unique, highly efficient drying system that uses 100% process air that passes through the product load for perfect system performance. The air outlet is diverted to the opposite side of the system to prevent any air turbulence in the spray area and thus provides better air flow and high drying capacity. The drying flow is automatically directed to the middle of the plant according to the batch size, product shape and process phase. Uniform airflow distribution, low airflow rate, high productivity, versatility, unique process design. Easy to clean and disassemble.
SHARK FIN BAFFLES - the patented 3D Shark Fin Baffles system combines high mixing performance with gentle product handling, which leads to uniformity of coating, allows for even distribution of the spray solution, thereby reducing the time of the coating process. These blades are versatile and have the same performance for any shape and size of coating.
All-Wall Pelletising Boilers - our coating systems use a smooth, electropolished, non-perforated, all-wall unit. The robust design, combined with our unique drying system, results in an unrivalled coating performance. In addition, the all-wall units are easy to clean and mix the required elements perfectly.
The Microlac Control System is an advanced, user-friendly software developed by Nicomac, PLC based on a control system that provides full automatic process repeatability. The user-machine interface with a computer touch screen for easy data acquisition and storage. The Microlac software allows for the storage of up to 40 different formulations and up to 99 discrete phases.
Patented Spray System - the stainless steel film coating and sugar guns combine a perfect mixing system and fast distribution of the solution over the walls of the drum. The guns do not clog. The special design of the pneumatic cylinder cover avoids this huge problem. The patented moving handle can be automatically controlled by an electric motor with the ability to adjust the position of the gun according to the requirements downloaded to the PC.
Humidity control - the main control process is based on the control of the closed loop temperature and the relative humidity of the air stream at the product outlet. Depending on the different applications, we have an algorithm for the correct process control. For temperature-sensitive products, the plant temperature is carefully monitored and controlled. The spraying ratio for film coating or the drying phase for sugar coating can be set based on the inlet/outlet humidity.
Patented THERMOJACKET System. In order to avoid heating dispersion on the outside of the drum, Nicomac has patented a new drying system, the THERMOJACKET. A part of the inlet air is directed to the Thermojacket system and it heats or cools the boiler drum from the outside, giving complete uniformity of the body temperature, reducing the heating dispersion, optimising the performance of the drying stage, reducing the process time.
Cleaning. As the units are not perforated, they can be quickly and easily cleaned with CIP (clean in place). The versatile installation with 4 spray heads located inside the equipment allows you to reach any point on the entire surface in combination with a flushing pump for highly efficient cleaning. The cleaning process is fast and efficient, even for enterosoluble shells and advanced film coatings such as Eudragit. The automatic rinsing cycle can be entered into the PC.
Automatic Drainage System - this patented system discharges the final product as well as the CIP wash liquid simply by rotating the drum using a magnetic, patented, quick-release discharge tray
Air Control - Nicomac systems use only an AC frequency controller to precisely control the inlet/outlet air flow without changing atmospheric pressure. The negative pressure inside the drum is automatically controlled by the programmable logic controller through the AC frequency control. This is a prerequisite for granulated products, enterosoluble shells and sugar coatings.
