The density of fruit concentrate has a direct impact on the flavour, texture and overall quality of the final product. Incorrect levels result in an inconsistent product that fails to meet consumer expectations and industry standards. Proper concentrations are essential for efficient processing in downstream stages such as filling, cooling or granulation. Incorrect measurements can lead to issues in these processes, causing production delays or the need for reprocessing, and specific gravity is important for the concentrate’s stability during storage. If the density is too low, the product may spoil or ferment more quickly, while a density that’s too high may cause crystallisation or excessively viscous consistency, making it challenging to handle and use later. These concentration levels directly affect the economic value of the product through the yield of the final product, impacting profitability. Many products have specific density requirements to comply with industry regulations and standards.
Keeping concentrate in check
Throughout the concentration process of fruit juice, it’s vital to address various challenges when assessing density. A noteworthy concern is the temperature during the process. As the juice undergoes concentration, its density increases while viscosity also rises, impacting fluid flow and density. The accumulation of residues, mostly due to the high sugar content of the concentrate, leads to sensor build-up, resulting in inaccurate measurements and requiring frequent cleaning and maintenance.
These difficulties highlight the importance of selecting a density measurement solution that can handle demanding conditions and provide accurate data. An optimal system should be able to withstand high temperatures, account for viscosity changes, alleviate fouling, and offer real-time data to enable continuous process control.
Concentrating on the measurements
Precise density measurement is essential for achieving the desired product quality during the concentration process. The VEGA Minitrac 31, VEGASOURCE 31, and the KV 31 mounting bracket present a fail-proof solution that effectively addresses the technical complexities associated with high temperature, viscosity and fouling. By selecting a VEGA solution, producers can achieve accurate real-time density measurements. This leads to better process control, reduced downtime and superior product quality.
The Minitrac 31 is a groundbreaking solution for the challenges of fruit concentrate production. This non-contact density sensor can accurately measure liquids and bulk solids, both internally and externally to the process. Unlike traditional methods, the Minitrac 31 avoids fouling issues, ensuring consistent and reliable performance. Its radiation-based technology delivers precise density measurements unaffected by temperature or viscosity changes. This leads to improved process control and optimisation. The compact design allows for easy integration and minimal disruption to existing systems.
The VEGASOURCE 31 is a gamma radiation source, and its robust shielding ensures safety without requiring additional precautions during installation or operation, simplifying regulatory compliance. Easily integrated into different setups, it provides the necessary radiation source without added complexity. When combined with the Minitrac 31, this system offers a compact, robust, accurate and secure density measurement solution.
The KV 31 mounting bracket is specifically designed to ensure the correct and secure installation of the Minitrac 31 and VEGASOURCE 31 on pipelines and vessels. Its adjustable measurement displacement angle provides flexibility, especially in applications demanding precise alignment for accurate density readings. The bracket simplifies installation without major modifications, making it ideal for fruit concentrate processes where optimal instrument positioning is crucial for reliable density measurements.
VEGA: A partner through thick and thin
Producing quality fruit concentrate demands precise density control. VEGA’s forward-thinking solutions provide the accuracy and reliability needed to meet these challenges. By overcoming the hurdles of high temperatures, viscosity fluctuations and fouling, VEGA instruments ensure consistent product quality, optimised efficiency, and adherence to industry standards. With VEGA technology, achieving the perfect density becomes a straightforward process, guaranteeing that every drop of concentrate meets the highest expectations.
