Downscaling right down to the laboratory –
Spray nozzles for tablet coating in research and development departments
In order to develop correct tablet coatings, until just a few years ago, pharmaceutical companies had to use coating drums, which wasted too many tablets in the test phase. Once the manufacturers of the coaters started to build more efficient tabletop units for research purposes, it was also clear to Düsen-Schlick that it would have to optimise its spray nozzles for these drum sizes.
Extremely fine spray
Professional spraying is gaining much more in importance as a technique, especially in the production of MDF board, as it is a very helpful way of reducing costs while maximising quality at the same time. With its newly developed SCHLICK Blowline, Düsen-Schlick is setting new benchmarks for the widely used technique of blowline gluing.
Maximum precision and reproducibility –
dosing nozzles for extruder injections
Extruders are plant systems frequently used within pharmaceutical manufacturing and food production to mould substances or modify them physically. When it comes to introducing precise amounts of additives, there are nozzles available which enable you to introduce low quantities and make precise, reproducible additions.
The newly developed SCHLICK design for all current atomisation technologies for two-substance nozzle and pressure nozzle applications. The sophisticated SCHLICK design with a minimal number of individual parts enables simple cleaning and fast conversion.
For decades, Düsen-Schlick has been supplying systems manufacturers and cigarette producers with process-optimised atomisation technology. Moistening and flavouring are core processes in the primary stage of tobacco processing. These are ultimately responsible for the flavour and quality of the final product. Properly measuring flavouring additives and uniformly moistening leaves and ribs ensure optimum cutting and drying properties. This also creates benefits for the downstream (secondary) stage of cigarette production.
Blocked spray nozzles are a widespread problem in fluidised bed systems in which very fine or tacky products are processed. By using ABC nozzles, the pharmaceutical excipient manufacturer DMV Fonterra Excipients has succeeded in avoiding unplanned downtimes. Düsen-Schlick Anti-bearding cap technology (ABC nozzles) is well-established in the field of tablet coatings.
Improved spray arm design and advanced nozzle systems cut set up time in half on state-of-the-art tablet coaters. This has big advantages for contract manufacturers who have find efficient ways of dealing with frequent changeover.
Anti-bearding air cap ensures that droplets are well distributed, and that coating and moistening are homogenous. The type of nozzle used for coating and moistening determines the process result. Normally, flat spray two-substance nozzles are used for this process. A new, robust air cap withstands even the most adverse operating conditions and thus ensures a clean spraying process with the ideal drop size.
Professional spraying in industrial wood machining, especially the production of boards, is gaining increasingly in importance. This is not just because of the increasing cost of energy and raw materials; it is also because increasingly high demands for quality in the manufacture of wooden boards encourage the demand for suitable processes and possibilities, in order to apply liquids as homogeneously as possible onto prepared base materials.
In a multitude of industrial fields, such as paper mills, glassworks, cement works, power plants, steel works, waste incineration, etc., cooling process gases in an economical and above all energy efficient way is becoming increasingly important. Evaporative cooling is the most effective way to cool and condition exhaust gases. By cooling the gases, a defined reduction in volume is achieved.
The SNCR and SCR procedures were developed for flue gas denitrogenation in order to meet the strict air purification requirements. Injection lances for the defined insertion of the reducing agent are an important component of both processes. These differ in their structural and procedural design depending on the application.
In the pharmaceutical industry, flat spray two-substance nozzles are used in coating drums for the coating of pharmaceutical products. If possible, the coating process should not be interrupted for economical reasons. In addition to the geometry of the coater, the drying air and the spraying liquid, the nozzles play a particularly important role in this process. A new nozzle with an antibearding cap (ABC-Technology®) meets the requirement for operating security and improved handling during coating.
Due to poor or incomplete combustion of the medium, soot is produced, and at the same time the emission values in the combustion chamber increase. With liquid fuels, combustion always takes place in the gas phase: The liquid fuel is first atomised, then vaporised, mixed with air, and finally burned in the gas phase. This article shows how atomisation can be influenced by various special nozzles.
Coating with sugar solution or chocolate is not only relevant in the food industry. In the pharmaceutical industry too, coating with sugar is used to mask taste and to preserve. Whilst traditionally the sugar solution is applied to the coated item by hand, the application in industrial processes is now carried out using nozzles, in particular those with a fan-shaped spraying pattern.

In tablet production, coating processes require a lot of manual operation and experience: The spray arms and nozzles that are used have to be constantly checked, and the spraying process variables require careful adjustment. A new nozzle and spray arm concept now allows you to achieve considerably more efficient processes.
Time and again conventional spray arms cause trouble when coating tablets. They are often difficult to clean and are not easy to inspect. The result is a disruption to the process flow and unnecessarily long set-up times. A new spray arm concept promises to improve this situation.
During flue gas denitrogenation, the addition of a reducing agent is used to transform nitrogen oxides into a substance that can be emitted without causing any damage or can be used again. The reducing agent ammonia is increasingly being replaced by innocuous urea. However, urea has a tendency to crystallise during atomisation. When observing the nozzle systems used in urea atomisation, it can be seen that trouble-free operation is not always guaranteed.
