Membrane Concentration of Orange Juice

A process to concentrate orange juice to levels above 42° Brix with quality close to fresh juice is discussed. Using ultrafiltration and reverse osmosis in a patented process, concentrate of superior quality can be produced. An overview of how membrane characteristics influence the design, selection and operation of the process is presented along with operating economics. Paper published with permission.

Citrus Irrigation With Reclaimed Wastewater

In 1986 the City of Orlando, Florida; Orange County; and area citrus growers implemented an innovative program to reclaim municipal wastewater for irrigation of citrus trees. This program, known as Water Conserv II, is planned to ultimately provide up to 50 million gallons per day of reclaimed water to as much as 15,000 acres of citrus grove land. In this paper, the authors present the program concept; identify public health issues that were considered; describe the facilities that were constructed to treat, transmit and distribute the reclaimed water; discuss operational factors and summarize initial observations of the project’s performance after the first two years of operation.

The T.A.S.T.E. Evaporator, Continuing Progress in Evaporator Technology

The term T.A.S.T.E. is an acronym for Thermally Accelerated Short Time Evaporator, which describes the primary advantages of this unique evaporator design. The combination of high temperatures, large heat transfer rates, and very short residence times are a direct result of the accelerated turbulent mist generated in the TASTE system.

Heat Exchanger Application and Theory

One of the most basic duties in the processing of fruit juices and drinks involves the economical, sanitary heating or cooling of products. These may be liquids or fluids of high viscosity or those containing particulate matter or pulp. The most commonly used forms of heat transfer equipment for these duties are the plate and tubular heat exchangers. Each is available in many different configurations and designs. Each is tailored to perform a variety of process duties while reducing fuel, water, and power consumption in keeping with the urgent need for better management of natural resources.
