COCOA & CHOCOLATE PROCESSING
Having greater control of the process also offers an opportunity to ensure efficiency and process repeatability when employing new ingredients such as sugar substitutes, fats and the various other ingredients that, alongside the chocolate itself, go into the increasingly complex recipes that are now being demanded by consumers. “Having accurate control of the refining process helps
ensure consistency of particle size, ready to be passed on to the subsequent conching stage,” continued Mauro. Many equipment providers today, including SACMI Packaging & Chocolate are also putting a focus on the need for greater energy efficiency in the chocolate production process. Keep an eye out for power management solutions such as inverter-controlled motor drive systems. “Our process R&D department has developed an energy saving system for our 5-roll refiners,” explains Mauro. “The use of inverters to drive the two main machine motors provides energy savings by re-using the braking power generated by the first roller motor during routine operation.”
Better process control is just as essential to ensure repeatable product quality when it comes to the downstream conching lines and this has been addressed by SACMI Packaging & Chocolate on both its single-shaft and dual stirrer conching solutions which now offer the ability to monitor a series of process parameters, the most important of which are temperature and the power transmitted to the product during all conching phases.
“Hygienically-designed
equipment will always be quicker to cleandown and so can offer huge benefits
for those looking for rapid turnarounds between batches”
Keeping it clean
Raf Tuytelaars, Sales and Marketing Manager at Hacos, says that while chocolate production equipment has seen many technology advances over the years, he believes that one of the most important considerations has really not changed that much – the need for hygienic design.
While there may be a cost premium for buying a piece of equipment that has been engineered to be hygienic – for example, to resist the build-up of contamination and to make cleaning fast and easy between different production batches – the reductions in downtimes for cleaning, in addition to reduced water and detergent consumption and energy required for cleaning, will more than justify the additional purchase price.
Developments relating to conches and refining machines have centred around advances in process control.
