SCHMIDT EVAPORATORS

Technology Schmidt technology is know-how. Know-how for the design of evaporation plants. It is distinguished by high quality results from the competence and creativity of our engineers. With over one hundred forty years of experience as manufacturers of heat exchangers and plants for thermal processing, we have had a major influence on evaporation technology. In processing liquids with suspended solids, Schmidt has made major contributions to the state of the art. We have been designing plants with plate evaporators for more than 40 years, and have been guided by the following objectives: n...

The SIGMASTAR® Evaporator Plate Due to their special construction, SIGMASTAR® evaporators can be used for nearly all evaporation processes. Especially for problem products (e.g. viscous streams, slurries, and liquids with fouling tendencies) which cannot be processed with falling-film evaporators, the SIGMASTAR® evaporator performs smoothly and successfully. The heart of the SIGMASTAR® evaporator is the SIGMASTAR® rising-film plate (Fig. 1 & Fig. 1.2). SIGMASTAR® plates have a heat transfer surface of up to 1.5m2. Only two plate types are needed, a “steam” plate and a “product” plate. The SIGMASTAR®...

The SIGMASTAR® Evaporator n Figure 3 shows an assembled SIGMASTAR®-90 evaporator. The evaporator plates are fitted in a frame. Perimeter bolts clamp the fixed and movable covers together. This compresses the gasket seal at the edges of the plate. The function of the flooded lower product chamber is to distribute the product evenly to the tubes. n The rising-film evaporation creates a two-phase flow: The generated vapors induce a product film on the tubes. The resulting mixture of liquid and vapors flows to the channel at the top of the plate. From there it flows forward to the fixed cover of...

Single and Multiple-Effect Evaporation The evaporation of liquids is, independent of evaporator type, always associated with high energy costs. Thus the energy cost is the major in the overall operating cost. With multiple-effect plants and the judicious use of thermal and mechanical recompression, energy consumption can be reduced. (Specific steam consumption under 3%). Single-Effect Evaporation The steam requirements for single-effect evaporation are approximately the same as the water removed, i.e. the heat contents of the vapor leaving the plant is roughly the same as that in the heating...

Juice Concentration with Aroma Recovery One of our most common applications is a concentration plant with SIGMASTAR® evaporators for fruit juice with aroma recovery. Evaporation capacity: 44,000 kg/h Concentration: from 12 to 72 % t. s. Steam Economy: approx. 25 % n For this product, preservation of original flavor and color was of utmost importance. Continuous operation coupled with extremely short residence times maintain the highest product quality. n This plant has an additional feature that makes Schmidt world-renowned. Our aroma plants produce the highest quality juices on the market. We...

Fine Chemicals and Pharmaceuticals Fields of application We have provided systems for acids (citric acid, etc.), bases (sodium hydroxide, etc.), salt solutions (ammonium nitrate and ammonium sulphate), aluminum sulphate, magnesium chloride, amine solutions (urea, etc.), alcohols (glycol, methanol, glycerine, etc.), aromatic compounds (toluol, xylene, etc.), raw and intermediate products for synthetic materials and fibres (caprolactam water), synthetic glue, pharmaceutical products (sorbitol, sorbose, enzyme solutions, antibiotics, monosodium glutamate), as well as many types of waste water. An...

Hydrolyzed Proteins Another typical installation Concentration plant with SIGMASTAR® evaporators for hydrolyzed proteins Evaporation capacity: 4,000 kg/h Concentration: from 8-12 to 50-58 % t. s. Steam Economy: approx. 22 % n For this product, consideration of many product specific characteristics led us to choose a 3-1-2 arrangement. Discharging the product at the slightly higher temperature of the second effect enabled a a troublefree solution for the final concentration. A thermocompressor ensured optimum economy. Continuous operation coupled with extremely short residence times maintain the...
