Process solution
Bronkhorst supplied three ES-FLOW ultrasonic flow meters. Each instrument measures the flow of coloring, flavoring and acid. Because these fluids are highly concentrated, only small amounts have to be added. These amounts can be measured with the ultrasonic flowmeter, as the measurement range is within 4 to 1,500 milliliters per minute with a precision of +/- 1 percent reading. The overall performance and user-friendly operation of the ES-FLOW flow meter is the main reasons for choosing this device.
The ES-FLOW is constructed and designed for hygienic applications. The flow meter is equipped with a straight SS316 sensor tube to ensure no dead volume and excellent cleanability. The display can be used for read-out and control and is mounted in the stainless-steel housing. The back of the display features a connector for connection to a pump or a control valve, and with proportional-integral-derivative (PID) control on-board, a process can be controlled through the display.
Natural colorings and flavorings are costly agents. Controlled and efficient use of these substances will yield a better-quality product and save on raw materials. By using the ultrasonic flowmeter, the quality control of the process is improved.
In the old days, poor quality was observed by looking at the candy at a rather late stage, resulting in entire batches of candy that had to be defined as “second choice.” Now, by using the ES-FLOW volume flow meter, poor quality — if any — will be detected earlier.
Depending on the type of candy to be produced, the amounts and types of colourings, flavourings and acids will vary. Because the ES-FLOW is liquid-independent and can be used for all liquids without recalibration, the devices are incorporated as standard option in Haas Mondomix equipment for confectionery manufacturing.
