Sugar Processing

Sugar plants sanitation is an important cretiria in the manufacturing process. Certain bacteria (Leuconostoc species) can lead to loss of sucrose in the juice by inversion, slime formation, and bad odor impacting final product quality. Metalub biocides directly address these conditions, preventing purity drop in the juice due to sucrose loss by inversion and controlling slime build up and bad odor.

Foam is a major nuisance during sugar production, unregulated foam levels can result in lower production rates, unsafe working environment, and even production shut down. Metalub has developed together with its customers defoamers for different applications and conditions. Our defoamers for washing and transport water are frost resistant, non-sensitive to pH changes, and will remain in the recirculating water for prolong periods. Metalub defoamers for sugar extraction exhibiting high performance at target temperatures ranging 40-90 Celsius, not sensitive to hydrolysis and will maintain effective through the entire process. All of Metalub defoamer comply to latest EU and US regulation and are Kosher (also for Passover) and HALAL certified.

At the sugar industry process equipment scaling and under deposit corrosion are serious problems of sugar plants especially at the evaporators. Heavy scaling occurs all along the evaporation line where the thin juice must be concentrated before crystallization. Without any treatment scaling is responsible for progressively dropping the production capacity and increasing the manufacturing costs and the demand of energy. At the final stage the sugar mill must be shut down for cleaning. Scale inhibitors are necessary to inhibit the deposition taking place in the different evaporators’ bodies. Metalub scale inhibitors are particularly recommended in beets sugar mills whenever the scale formed is mainly based on calcium carbonate, calcium oxalate and calcium sulfate. Optimization of the treatment with Metalub scale inhibitors is generally reached by injecting the product in different injection points of the evaporation bodies.
