Pre-Concentrator Evaporators
If an evaporator is the constraint in a processing system a C. E. Rogers MVR Pre-Concentrator could be the most effective means to increase production capacity requirements.

A MVR evaporator used as a pre-concentrator can solve this problem of a limited production capacity. By using a C. E. Rogers MVR Pre-Concentrator in conjunction with their existing evaporator system, a processor can many times, double the amount of product processed.

EXAMPLE: A four effect falling film TVR evaporator system is capable of processing 45,000 lb/hr of sweet whey from 6.0% TS to 52% TS. The installation of a single effect MVR pre-concentrator, capable of concentrating 90,000 lb/hr of sweet whey from 6.0% TS to 11.7% TS, will allow the present four effect TVR to process 45,000 lb/hr of sweet whey from 11.7% TS to 52% TS. A 100% increase in overall product processed.

The C. E. Rogers Company's MVR evaporator design used for pre-concentration (before entering an evaporator for high solids concentration) can be a more cost-effective alternative to a membrane system. The MVR pre-concentrator is highly efficient and requires very little maintenance.

The following is a list of some of the Pre-Concentrator evaporation systems that have been installed by C. E. Rogers Company:

EQUIPMENT / CAPACITY / PRODUCT / YEAR

Single Effect MVR Pre-concentrator, 1996
85,000 lb/hr, Skim Milk 8.6% TS to 14.6% TS

Single Effect MVR Pre-concentrator, 1995
90,000 lb/hr, Whey 6.0% TS to 11.7% TS
