How to size an industrial dryer for a dyehouse

The drying stage should be evaluated together with the machines upstream. Batch size, cycle frequency and the amount of material leaving dyeing determine the drying capacity the department needs. A correctly sized system helps maintain a balanced flow between dyeing, drying and the next production steps.

Key points to evaluate include:

• average quantity of textile product to be dried per cycle;
• batch frequency and required production continuity;
• relationship between dyeing capacity and drying capacity;
• available floor space and department layout;
• energy-efficiency goals and acceptable process times.

TD 50, TD 100 and TD 150 for sampling and small productions

TD 50 is positioned for sampling tests and small productions, where a dedicated dryer can handle contained quantities without tying up equipment sized for larger output. TD 100 serves the same production bracket, while TD 150 is the largest model in the group for users who need more drying capacity while still working with relatively small batches.

Flainox documentation for TD 100 highlights a robust fixed structure and several heating options, including steam, electric, gas and diathermic oil. It also lists a touchscreen display, temperature monitoring and inverter-driven transmission for recipe customisation. Optional technologies include ThermoShell insulation, a basket for delicate materials, infrared temperature sensing and a humidistat.

TD 250 and TD 330 for medium production volumes

TD 250 and TD 330 are designed for medium-scale production. They sit between the sampling range and the large-production models, making them relevant when small-batch dryers no longer support the required throughput but a large-scale unit would be disproportionate to the actual workflow.

For a dyehouse reorganising its production line, this middle range can help maintain continuity without oversizing the drying stage. The decision should still be based on the number of cycles, the variability of batches and the output of the dyeing machines feeding the dryer.

TD 400, TD 500 and TD 600 for large-scale production

TD 400, TD 500 and TD 600 are designed for large production volumes. In this part of the range, drying capacity becomes especially important because the equipment must support a steady flow of material and avoid slowing down a department operating with higher dyeing output.

The correct industrial dryer should therefore be selected as part of the complete production flow: quantity leaving dyeing, available cycle time, number of daily batches and handling requirements all influence the most suitable configuration.

TD range by production scale

Drying efficiency and process control

Drying quality depends on airflow, temperature control, load behaviour and the way the cycle is managed. For example, the TD 100 SmartDry version uses a heat exchanger to recover heat from exhaust air and transfer it to incoming air before the steam coil; Flainox states steam savings of more than 20% for this configuration. This is a concrete example of how dryer technology can contribute to process efficiency.

Flainox develops dyeing and finishing technologies with attention to resource use and environmental impact. The wider approach to ECO-DESIGN and consumption reduction is described on the Sustainability page.

How to choose the most suitable TD model

Start from measured production data: quantity per cycle, number of cycles, batch variability and the capacity of the dyeing machines already installed. This makes it easier to identify the correct TD group and prevents the choice from being based only on a generic capacity label.

The dryer range completes the wider Flainox garment dyeing offer alongside atmospheric machines, pantyhose systems and high-temperature equipment.
