FROM FEASIBILITY TESTING TO SMALL SCALE PRODUCTION
VTA offers glass laboratory units to determine feasibility of the distillation process by only using small product amounts. These units are offered as single- and multi-stage wiped film or short path distillation plants.
The key components in lab scale systems are fabricated in borosilicate glass. This enables observation of product properties like foaming, fouling and film distribution on the heated shell during distillation. Glass plants equipped with continuous feed and discharge systems allow the production of sample amounts up to several kilograms.
