The Art and Science Behind Electron Machine Corporation's Refractometers

The Art and Science Behind Electron Machine Corporation's Refractometers

Electron Machine Corporation is known for high-quality industrial-grade process refractometers. Here's a general explanation of the principles, technologies, and construction behind their refractometers.

Principle of Refractometry:

A refractometer operates on the principle of refraction. When light passes from one medium to another, it changes direction, called refraction. A refractometer measures the degree to which the light changes direction, i.e., the angle of refraction.

A process refractometer uses this principle to measure a process fluid's refractive index (RI). The refractive index measures how much the speed of light reduces within the fluid. It's a characteristic property of each substance and is influenced by temperature and concentration. For solutions, the refractive index can be used to determine the concentration of solutes in the solution, and this is how process refractometers find application in industries.

Technology Behind Electron Machine Corp. Refractometers:

Here's an overview of how these refractometers may function:

  1. Light Source: A light source emits light into the prism assembly. This light source is usually a long-life LED.
  2. Prism Assembly: This is where the process fluid comes in contact with the refractometer. The prism assembly usually contains a high-refractive-index glass prism that comes into contact with the process fluid. The light from the source enters the prism and is refracted (or bent) when it exits the prism into the process fluid.
  3. Detector: After the process fluid refracts the light, it hits a linear photodiode array, the detector. Depending on the refractive index of the process fluid, the angle of the light will change, causing the light to hit the detector at different positions.
  4. Signal Processing: The refractometer's electronics convert this positional information into a digital signal converted to a refractive index measurement. The device uses the known refractive index of the prism and the angle of refraction to calculate the refractive index of the process fluid.
  5. Temperature Compensation: Since the refractive index is temperature-dependent, high-quality refractometers will also include a temperature sensor to measure the process fluid's temperature. The device will then apply temperature compensation to correct the refractive index measurement.
  6. Output: The refractive index or the converted measurement related to the process (like Brix in the food and beverage industry, concentration in the chemical industry, etc.) can be communicated to a central system using standard industrial communication protocols.

Rugged Design and Construction of Electron Machine Refractometers

The refractometers manufactured by Electron Machine Corporation are rugged. They are designed for industrial use in harsh conditions with high temperatures, significant vibrations, and heavily contaminated settings. The refractometer withstands extreme conditions that damage conventional equipment, including considerable temperature fluctuations, high vibration levels, humidity, dust, and potential physical shocks or impacts. They have robust electronics and casings and are built to resist wear and tear, thereby ensuring reliable operation in challenging environments.

Qualitative Analysis of Black Liquor in the Kraft Process

Qualitative Analysis of Black Liquor in the Kraft Process

Black liquor is a byproduct of the Kraft process of paper production. The Kraft process, also known as the sulfate process, is a method of pulping wood chips to produce wood pulp, which is then used to make paper. In the Kraft process, wood chips are cooked in a solution of sodium hydroxide (NaOH) and sodium sulfide (Na2S) at high temperatures and pressure. This chemical cooking process breaks down the lignin and cellulose in the wood chips, separating the fibers that can be used to make paper.

During the cooking process, a black, viscous liquid known as black liquor is produced. Black liquor contains lignin, hemicellulose, and other organic compounds that are dissolved or suspended in the cooking liquor. It also contains inorganic chemicals such as sodium hydroxide and sodium sulfide, as well as dissolved minerals from the wood chips.

Black liquor is separated from the wood pulp during the pulp washing and recovery process. It is then burned in a recovery boiler to generate steam and electricity for the mill. The heat from the burning black liquor drives a steam turbine, which generates electricity that can be used to power the mill and any excess can be sold back to the grid. The inorganic chemicals in the black liquor are also recovered and recycled back into the Kraft process.

Process refractometers are used in paper mills to analyze black liquor in order to determine its concentration and solids content. The concentration of black liquor can have a significant impact on the efficiency of the pulping process, so it is important to accurately measure it.

To use a process refractometer to analyze black liquor, a sample of the liquor is typically collected and placed in a sample cell. The refractometer then measures the refractive index of the sample, which is a measure of the way that light is bent as it passes through the sample. The refractive index of the sample is then used to calculate the concentration of the black liquor.

Process refractometers are widely used in paper mills because they are fast, accurate, and easy to use. They can also be used to measure the concentration of other process fluids, such as process water and spent cooking liquor.

In the context of fruit juice production, inline process refractometers are used in the production of fruit juices to measure the concentration of soluble solids in the juice as it is being processed. The concentration of soluble solids is an important quality parameter in fruit juice production because it determines the sweetness and flavor of the juice. Feedback from the refractometer adjusts the concentration of the juice by adding or removing water or other ingredients to achieve a desired level of sweetness or other desired characteristic.

To use an inline process refractometer in the production of fruit juices, a small sample of the juice is analyzed directly in the production line through the refractometer's measurement prism. The refractometer then measures the refractive index of the juice sample as light passes through the sample. The refractive index is directly related to the concentration of soluble solids in the juice, so the refractometer can calculate the total dissolved solids (TDS) of the juice by using a pre-determined conversion factor. 

By accurately measuring the concentration of dissolved solids in the juice, a process refractometer can help to ensure that the juice meets quality standards and has a consistent flavor profile. It can also be used to optimize the juice production process by helping to identify bottlenecks or inefficiencies and allowing for adjustments to be made to improve efficiency and reduce waste.

Inline process refractometers are typically used in conjunction with other process control instruments, such as pH meters and temperature sensors, to ensure that the juice is being produced to the desired specifications. They are also commonly used in the production of other beverages, such as beer and wine, as well as in a variety of other industrial processes.

Overall, the use of a process refractometer can help to improve the quality of fruit juices by ensuring that they meet desired standards for sweetness, flavor, and other characteristics, and by helping to optimize the production process.
