Radar Level Gauge Measures Scraper Vacuum Evaporator Levels

Scraper vacuum evaporator is a common industrial equipment, widely used in the process of liquid concentration and evaporation in the fields of chemical industry, food, pharmaceuticals, and so on. In order to accurately monitor the liquid level in the evaporator, radar level meters are widely used. 

In this paper, we will introduce the characteristics of the scraper-type vacuum evaporator and provide two actual measurement cases to demonstrate the application of radar level meters in this area.

Scraper-type vacuum evaporator has the following features, high-efficiency evaporation: scraper-type evaporator adopts scraper-type heating to evaporate liquid under a vacuum environment. 

With the ability of high-efficiency evaporation and liquid concentration, it can process a large amount of liquid quickly. Adjustable liquid level: The scraper evaporator has an adjustable scraper position so that it can control the liquid’s start and end level. 

Accurate measurement of the liquid level is critical to the effectiveness and yield of the evaporation process. Versatile operation: Scraper evaporators can be used for a variety of operations such as solvent removal, solvent recovery, concentration, and separation. Therefore, accurate monitoring of the liquid level is essential to ensure the success and safety of these operations. 

Corrosive substances: In some cases, scraper evaporators may handle corrosive substances. 

Therefore, level measurement equipment requires corrosion-resistant materials and appropriate protective measures.

Let’s look at it through two cases. Case 1: In a scraper vacuum evaporator in a chemical plant, the solution produced by a chemical reaction needs to be concentrated. 

To ensure the effectiveness and safety of the evaporation process, the level of the solution needs to be accurately monitored. Conventional float level gauges may be limited by the viscosity of the solution and the evaporation conditions, so radar level gauges are used for the measurement. 

The radar level meter performs non-contact measurement through microwave signals and is able to accurately measure the level of the liquid in the scraper-type evaporator. 

By connecting the measurement data to the control system, the operator can monitor the liquid level changes of the solution in real-time and make corresponding adjustments to ensure the effectiveness and yield of the evaporation process. 

Case 2: In food processing, scraper vacuum evaporators are often used to concentrate food ingredients, such as fruit juice or dairy products. In these applications, accurate measurement of liquid level is important for product quality and process control. 

Radar level gauges provide reliable level measurements that accurately measure the level of the liquid in the squeegee evaporator. This enables processors to monitor level changes to ensure accurate and repeatable process operations, thereby improving product productivity and quality. 

In addition, radar level meters can be integrated with other control devices to automate liquid level control. For example, in a scraper-type vacuum evaporator, when the liquid level reaches the set value, the radar level meter can be connected to the heating control system to automatically adjust the heating power to keep the liquid level stable within the required range. 

This type of automated control improves productivity and reduces the risk of human intervention and operational errors.

Radar level meter has a wide range of applications in level measurement of scraper type vacuum evaporator, which can accurately measure the level of liquid in the evaporator to meet the requirements of chemical, food, pharmaceutical, and other industries for liquid level measurement. 

By providing high accuracy, stability, and corrosion resistance, radar level gauges help operators monitor liquid level changes in real-time and integrate with control systems to realize automated liquid level control. 

These advantages make the operation of scraper vacuum evaporators more reliable and efficient while improving product quality and productivity.
