Scale-up of the jetcutter technology

Abstract

The JetCutter is a new, simple and efficient technology for the high throughput encapsulation of various materials inside spherical beads. Monodisperse beads in the particle size range from approximately 0.2 mm up to several millimeters can be prepared at high throughput rates with the JetCutter. The generation of beads is not limited by the fluid viscosity. Thus, also highly viscous fluids even with high loadings of solids, can be processed, which leads to an improved stability of the resulting beads. The JetCutter technology is available in different scales and corresponding throughputs ranging from lab-scale devices (liters per day) up to large scale installations for industrial production purposes (tons per day). The application of the JetCutter for industrial purposes has been well established by geniaLab®, which currently produces more than 40 tons/year of small hydrogel beads

Review on the Production of Polysaccharide Aerogel Particles

“…Figure 4 shows that a stream of droplets production can be modified from single- to multi-stream by varying the design of cutting discs. Depending on the desired throughput, different installations can be carried out such as multi-nozzle system, designing the cutting wires and multiunit installations [83].…”

Production of κ‐carrageenan beads by prilling process

“…For larger scale production, especially producing small beads, the liquid flow rate is increased to reach the formation of a liquid jet. The jet is then broken into droplets either by applying a specific vibration on the jet or by passing the jet through a rotating cutting wheel . As such, the productivity by nozzle is increased by a factor of 10 or more, reaching litres per hour.…”

“…The jet is then broken into droplets either by applying a specific vibration on the jet [5] or by passing the jet through a rotating cutting wheel. [15] As such, the productivity by nozzle is increased by a factor of 10 or more, reaching litres per hour. The initial drop velocity is not zero and is mainly equal to the jet velocity.…”
