Gum Bases |
||
Underwater pelletizing of all gum base variants produces very good results. Gum bases are easy to handle - no processing problems are to be expected. Gum bases are easy to pelletize in the ball shapes and sizes demanded by the market. Advantages The advantage of underwater pelletizing in this field is the good cooling of the pellets in the water flow. The floor space requirements are low since cooling of the pellets takes place in long pipes. Special designs and cleaning requirements of the food processing industry can be easily incorporated. Underwater pelletizing produces ball-shaped pellets that do not have any linear adhesion surfaces even after leaving the water flow, as are known from standard drop and/or pastille shaped pellets. Gala systems permit pelletizing gum bases of a viscosity as from 3000 mPas. Products with lower viscosity are processed using a melt cooler before pelletizing. Reasons for preferring a Gala underwater pelletizing system: • Low capital expenditure • Low space requirements • Low energy costs • Low tooling costs • Fully automatic and redundant design • Low sound pressure level < 80 db(A) For these applications, pelletizing systems are available for installation downstream of extruders but also for use with mixers and kneaders with melt delivery pumps. |
