Krones SyPro S sugar-dissolving and pasteurisation system

Krones has revamped its sugar-dissolving and pasteurisation system. The entire SyPro S sugar preparation unit is modular in construction, so that it can be individually expanded as needed and adjusted to suit raw material qualities. The concept has been designed for energy economy, with appropriate measures for heat recovery incorporated.

The system is mounted on a frame as a plug-and-play solution, and serves as an important input stage for the production process of a range of soft drinks.

The continuous sugar-dissolving unit primarily consists of a tank holding the water being used, a pre-warming water unit, an internal dissolving circuit with separator strainers and a Brix-controlled syrup flow channel leading to the downstream process (eg, the pasteuriser).

The compact sugar-dissolving unit has been pre-assembled on a frame, can be shipped in a container and integrated into any existing process ready for operation. According to the company, this unit philosophy improves conditions and reduces the time for commissioning.

An integrated control function, which can be linked to a higher-order control system, ensures that the concentration desired for the sugar solution is reliably set, with minimised deviations of ± 0.1°Brix. This concentration is then continuously passed onto the next processing step.

The inlet nozzle in the dissolving tank aids the complete dissolution of the granulated sugar. Without the need for any additional pump or agitator, the nozzle’s design helps achieve complete blending, irrespective of the fill level obtained in the dissolving tank, giving shorter dissolving times and reduced energy consumption.

The system is available in two performance categories of 7.5 to 15, and 15 to 30 m³/h, with reference to a sugar syrup of 65°Brix. In both sizes, the process can be adjusted between full and half throughput.
