The Inline Refractometer's Role in Juice Concentration

Orange juice
Fruit juice concentrate provides producers easier transport of product and longer storage life. Fruit juice concentrate production starts with a dilute feed stock juice and processes it into a uniform and consistent concentrated form through the removal of water. Water is removed through an evaporative process that involves specialized equipment designed uniquely for the concentration process. Almost every commercially harvested fruit can be juiced and concentrated.

Fruit juice extraction is unique to the shape, size, and nature of the fruit, but once the juice is extracted it is purified and stored in primary holding tanks prior to being delivered to an evaporator. Upon entering the evaporator, the juice concentration varies depending on a number of natural factors. The goal of the concentration process is to remove this variability and output a uniform and consistent juice concentrate.  Throughout the fruit juice concentration process, solid components of the original juice remain and can be quantified as a percent of juice volume.

Refractometers are instruments that measure the refractive index, which very simply put, indicates how much a light beam is "bent" as the light passes through the fruit juice.  The light bending is proportional to the solids concentrate. Sugars are the major soluble solids in fruit juice, along with other soluble materials including organic and amino acids, soluble pectins, etc.

In larger scale juice production facilities, soluble solids concentration (SSC%, degrees Brix) are determined by using in-line process refractometers at strategic points in the process to measure solids concentration, as well as to evaluate equipment performance and product quality. Output signals from the refractometers serve as inputs to the command and control system for the evaporators, allowing feed rate to closely match evaporation rate and make most efficient use of the energy consuming equipment.
