Tecweigh, a specialist in industrial feeding systems, has introduced the TT20 gravimetric controller, a product designed to enhance the functionality of its existing range of volumetric auger feeders.
With this addition, Tecweigh offers precision, flexibility, and control over material handling, making the TT20 an upgrade for industries ranging from food production to agriculture and bulk material processing.
This range, which also offers reliability, includes three models tailored to different throughput and application needs.
The S5A model, for example, is suitable for small-scale, loss-in-weight dosing applications and is used for dispensing food flavourings, spices, and salt. Then there is the S12A, which caters to higher throughput requirements and is often paired with a tear drop auger for dosing across conveyors in agricultural settings.
At the top end of the scale is the S28A, capable of handling throughputs of up to 30,000 litres per hour, making it suitable for large-scale drum and bag filling operations.
The core benefit of the new TT20 gravimetric controller is its ability to improve the accuracy of these systems by measuring weight changes through a scale base or load cells.
This precise control opens a host of new possibilities for applications that demand high levels of precision. With the TT20, Tecweigh feeders can operate in four different modes: Loss-in-Weight, Loss-of-Weight, Gain-in-Weight, and Controlled-Rate Batching, providing users with flexibility to tailor the system to their specific needs.
The most used mode, Loss-in-Weight, allows the volumetric feeder to sit on a scale base, dispensing material until the desired amount is reached. The TT20 controller continually monitors the weight of the material being dispensed, ensuring consistent flow and rate.
When the hopper begins to empty, the TT20 signals that a refill is required and compensates for this, maintaining the same feed rate even as the hopper is replenished. This dynamic refilling feature ensures that feed rates remain constant and accurate throughout the dispensing process.
Another key mode offered by the TT20 is Gain-in-Weight, which is typically used in controlled weight batching applications. In this mode, the drum or bag receiving the material sits on a scale base. The system fills the container until it reaches a pre-set weight, ensuring accurate and consistent batching.
This mode is useful for applications where precise ingredient quantities or material weights are critical, such as in food processing or chemical manufacturing.
In addition to the core operational modes, the TT20 also includes features designed to refine and optimise system performance. For example, adjustable feed rates allow for both fast and slow dispensing, and the system provides in-flight compensation to maintain accurate dispensing during transitions.
The controller’s diagnostics and tuning functions also make it easier for operators to troubleshoot and optimise the performance of the system, ensuring that the feeder continues to meet operational requirements even under changing conditions.
Another feature is the inclusion of product massaging paddles. These paddles are designed to prevent common material flow issues such as bridging or “ratholing,” where materials become stuck or fail to flow consistently from the hopper.
The TT20 controller manages the speed of both the auger and the massaging paddles independently, ensuring optimal material flow and reducing the risk of blockages. This feature is particularly beneficial when dealing with challenging or inconsistent materials that tend to clog or jam under normal conditions.
The construction of Tecweigh feeders is another point of distinction. All models are built using high-quality stainless steel, ensuring durability and resistance to corrosion.
For food-related applications, the inlet flex hopper is made from food-grade polyurethane, meeting stringent hygiene and safety standards. These materials contribute to the overall longevity and performance of the feeders, making them suitable for continuous operation in demanding industrial environments.
The TT20 controller is also equipped with PLC communication protocols, allowing it to seamlessly integrate with a plant’s central control system. This makes it easier for operators to monitor and control the feeder system remotely, as well as to collect data for analysis and reporting.
For applications requiring even higher throughput, or the handling of larger bulk products, Tecweigh offers a stainless-steel weigh belt feeder.
This system is equipped with a wave edge belt, designed to maximise product containment, and prevent spillage, which is essential when dealing with larger volumes or products like vegetables.
The weigh belt feeder offers a reliable solution for industries that need to handle substantial quantities of bulk materials with precision and efficiency.
With the launch of the TT20 gravimetric controller, Tecweigh has expanded the capabilities of its Volumetric Auger Feeders.
The system’s enhanced accuracy, flexibility, and ability to manage material flow challenges make it a suitable solution for a range of industries, from food processing to agriculture, chemicals, and more.
The TT20 is not only helps improve operational efficiency, but also a key step forward in meeting the increasing demand for precision and automation in industrial material handling.
As industries continue to evolve, Tecweigh’s commitment to innovation ensures that its systems provide users with the tools they need to optimise their processes and achieve high standards of efficiency and accuracy.
