Ethanol or ethyl alcohol is a hydrocarbon compound that can be produced by fermentation. Ethanol production is generally the use of scraps from industries for production. Can be divided into 3 types: raw materials containing starch such as cassava, lignocellulosic materials such as straw, corn cobs or sugar materials such as sugarcane and molasses, which are derivative products of the sugar production process as raw materials for use. Use ethanol as raw material. a fuel. We will give an example of ethanol production using molasses and how it works. What equipment or analytical tools can be used to make the ethanol production process more efficient? Use molasses to produce ethanol by fermentation and distillation to obtain pure alcohol. First we must dilute the molasses with water to get the right concentration before starting the fermentation process with yeast. We can use analyzer to control the concentration. After achieving the correct concentration, it is used to ferment molasses with yeast at the optimal temperature of 30-35 ◦C for 2-3 days. After that time, the sugar will convert into alcohol. Use an analyzer to analyze the ratio of alcohol and sugar. Then distill it again to reduce the water content until it becomes pure alcohol. Ethanol must be pure alcohol with a concentration of about 95-99.5% before being put into the tank. Waste and by-products from ethanol production such as biogas and carbon dioxide will be produced. Which one can be used or discarded, it depends on the operator’s production technology. Furthermore, ethanol will be blended with gasoline as fuel. It provides cleaner fuel and burns more efficiently when mixed in the proper proportions. As a result, air pollution is reduced. It’s also great for the environment.

Sanitary refractometer PR-43-A

The PR-43-A cleaning system includes a compact refractometer or probe for Brix monitoring. Conversion rate and alcohol content (%) can be specified. It has a measurement range of 0 to 100 Brix and provides an Ethernet or 4–20 mA output signal proportional to the temperature-compensated Brix value for real-time process control with a graphical user interface that helps it works effectively. The PR-43-A refractometer has a web server integrated with the device’s home page. The home page allows configuration, monitoring, verification and diagnostics of the refractometer via an Ethernet connection. Easy to install and lightweight, compact

The main benefits of refractometers for winemaking processes

• 3-A HYGIENE APPROVED The 3-A symbol ensures that the PR-43-A Sanitary Refractometer complies with 3-A hygiene standard No. 46-04 for refractometers and absorption optical sensors Energy is used on the liquid product device to sense concentration and it has passed independent third-party verification testing to grant the 3-A designation.
• Accurate and stable measurement Accurate measurement over the entire concentration range 0-100 Brix: R.I. nD ±0.0002 typically corresponds to ±0.1 Brix or % by weight. Measurement is not affected by bubbles, particles, color or vibration. The system withstands CIP and SIP cleaning.
• No regular maintenance required There are no moving parts in the refractometer that require regular maintenance. Fully digital instrument. Calibration does not drift. No need for recalibration and mechanical adjustment.
