REDA MULTIPLE‐EFFECT EVAPORATOR for concentration of juices, milk ,whey and other special products,5000Ltr/hr

 

Operating Characteristics

Multiple-effect evaporator of REDA is a multi-purpose equipment ideal for concentration of a large amounts of heat sensitive products like juices, milk, whey and others.
The first effect works at max +65/70°C and it comes heated not by steam but by means of hot water at max +70/75°C. The product flows very quickly in the circuit so that no thermal damages are possible. The second effect works at around +50/55°C and recovers the heat derived from the condensation of the vapors in the first effect. The last effect works at +40°C and uses tower water at +25/30°C for the condensation of vapors. Tower water is cooled by a specific evaporation tower that may be included in the supply. Then finally, the product comes cooled before the outlet from the unit.

The three-stage low-temperature concentrator performs evaporation of water at low temperatures, is fully automated both in the operating cycle and in the washing cycle. Installation is intended for processing temperature-sensitive products.
At the first stage, evaporation occurs at a temperature of 60-65 ° C, at the second - at 45-50 ° C, and at the third - at 25-30 ° C.
The unit is designed in accordance with all the rules and regulations used in food production in order to ensure the accuracy of technological processes, washing with a central CIP system and ease of maintenance.
The installation is NOT a vacuum spray device (having the problem of "burning" the product on the walls) and the whole process takes place in closed tube and plate heat exchangers. In this regard, it is GUARANTEED for constant and easy washing of the parts that are in contact with the product.
The concentration level is controlled by refracto-measure, which automatically controls the concentration of the finished product.
The unit is capable of concentrating the product with the declared capacity with a solids content from 12% to 45-50%, with reduced productivity - up to 50-60% solids.
