Spot Dryer APPLICATIONS in Industrial Environments
Introduction
The Spot Dryer has transformed drying and debris removal across various industrial applications, offering an energy-efficient and cost-effective alternative to traditional compressed air nozzles. From pre-date coding surface preparation to sensor maintenance, the Spot Dryer delivers targeted solutions that improve product quality and line efficiency while providing substantial energy savings.
These case studies illustrate how the Spot Dryer optimises performance, enhances reliability, and drives down costs for operations, quality managers and purchasing professionals.
#1. PRE-DATE CODING SURFACE PREPARATION
THE CHALLENGE
The quality control team was frustrated with smudged and unreadable date codes on cans at a beverage canning facility. Moisture from the pasteuriser left droplets on the can bevel, causing date codes to smear or not adhere properly. These errors led to rejections from retail partners and costly production delays.
THE SOLUTION
The facility implemented the Spot Dryer just before the date coding station. The high-efficiency centrifugal blower provided targeted airflow, ensuring the tops of cans were completely dry before coding. The running cost was only £0.05 per hour compared to £0.81 for their old compressed air system, resulting in a 94% reduction in energy consumption.
THE OUTCOME
The plant saw a dramatic decrease in date coding errors, reducing wasted cans and rework. Energy savings amounted to £30.27 over 40 hours, and the team achieved an ROI in 44.6 weeks. Quality assurance noted improved code clarity and retail partners commended the consistent, readable codes on every shipment.
#2. MEDICATION BLISTER PACK POSITIONING
THE CHALLENGE
In a pharmaceutical manufacturing plant, maintaining the precise positioning of medication blister packs on the conveyor before the next processing stage was critical. The existing system used compressed air nozzles to blow the blister packs into the correct position.
However, the setup was inefficient, leading to frequent misalignments and line stoppages. These issues caused production delays and compromised product quality, negatively impacting the plant’s ability to meet regulatory standards.
THE SOLUTION
The plant replaced the compressed air nozzles with the Spot Dryer, which provided a powerful, targeted airflow to position blister packs on the conveyor precisely. The unit’s compact design integrated seamlessly into the existing production line. The cost of drying decreased from £6.44 to just £0.33 per 8-hour shift, offering substantial energy savings.
THE OUTCOME
With the Spot Dryer in place, the blister packs stayed perfectly aligned, significantly reducing production stoppages. The plant saw a 94% decrease in energy costs, saving £61.09 over 80 hours of use, and achieved an ROI in just 29.5 weeks. Minimising misalignments made the manufacturing process smoother, ensuring compliance with stringent industry standards and improving overall efficiency.

#3. Air Rinsing Palletised Cans
THE CHALLENGE
A beverage canning facility receives its empty containers on pallets. The depalletiser unloads the cans onto the production line. They pass through a twister where the cans are air rinsed to remove any potential dust or debris inside. The plant’s existing air rinsing method used compressed air nozzles, which were not only costly but also carried the risk of oil contamination, thus jeopardising product safety and quality.
THE SOLUTION
The plant replaced the compressed air nozzles with the Spot Dryer, which provided a powerful, oil-free, and energy-efficient airflow. Positioned on the conveyor, the Spot Dryer effectively cleaned the cans, ensuring they were free from contaminants before proceeding to the next stage.
This change also significantly reduced energy costs, from £0.81 to just £0.05 per hour.
THE OUTCOME
The Spot Dryer ensured the cans were thoroughly cleaned without the risk of oil contamination, meeting the plant’s stringent hygiene and quality standards.
Over 120 hours, energy cost savings amounted to £90.80, and the company achieved an ROI in 29.7 weeks. The production line experienced fewer disruptions, with improved efficiency and higher quality assurance satisfaction regarding the cleanliness of the cans.
#4. Sensor Clearing and Maintenance
THE CHALLENGE
A cardboard factory used automated sensors with reflectors. These sensors monitored the production line to ensure that cardboard sheets were cut and processed correctly.
However, the facility’s dusty environment from cutting and handling cardboard caused dust to collect on the sensor reflectors. This buildup frequently interfered with sensor functionality, leading to inaccurate readings, line stoppages, and costly disruptions. Maintenance teams were forced to frequently stop the line to clean the reflectors, reducing overall productivity.
THE SOLUTION
The Spot Dryer was installed to provide regular, powerful airflow aimed at the sensor reflectors, freeing them from dust and debris without manual intervention.
Switching from a compressed air system, which cost £6.44 per 8-hour shift, to the Spot Dryer at just £0.33 per shift saved the facility significant energy costs.
THE OUTCOME
The sensors maintained high accuracy, ensuring smooth operation of the production line with fewer interruptions. This led to energy savings of £60.54 over 80 hours, achieving an ROI in 29.7 weeks.
Maintenance teams could redirect their efforts toward preventive maintenance rather than frequent emergency cleanings, resulting in increased efficiency and overall productivity gains for the plant.

#5. Packaging Line Improvement
THE CHALLENGE
A bakery producing packaged pastries faced challenges related to excess glaze on the surface of the pastries. The sticky glaze caused pastries to adhere to the packaging, resulting in damaged products and customer complaints. The excess glaze also made packaging machines less efficient, causing delays and frequent stoppages.
THE SOLUTION
The Spot Dryer was installed at the end of the glazing line to deliver targeted airflow, effectively removing excess glaze from the pastries before packaging. This ensured the pastries were adequately prepared for smooth handling and packaging without sticking issues. Additionally, the Spot Dryer reduced energy costs from £0.81 to £0.05 per hour, providing the bakery with significant savings.
THE OUTCOME
The pastries were packaged efficiently, without sticking or damage, significantly reducing product waste.
The bakery saved £30.27 over 40 hours and achieved an ROI in 44.6 weeks. Packaging machines ran more smoothly, with fewer stoppages, which increased overall output and ensured higher customer satisfaction.
#6. Inspection Stage Optimisation
THE CHALLENGE
The inspection stage is critical for quality control at a bottle manufacturing plant. The process involves checking the top of each bottle or under the cap for proper sealing and measuring the container’s height to ensure it meets precise specifications. However, when moisture is present at the top of the bottle or below the cap, the inspection system reads a false negative, interpreting the bottle as improperly sealed and leading to unnecessary rejections. This results in increased waste and production inefficiencies.
THE SOLUTION
The Spot Dryer was installed at the inspection stage to provide targeted airflow, removing moisture from the top of the bottle and under the cap before the quality checks.
This ensured the inspection system received accurate readings, preventing false negatives. The Spot Dryer’s energy-efficient design also reduced drying costs from £6.44 per 8-hour shift with compressed air to just £0.33 per shift.
THE OUTCOME
With the Spot Dryer in place, false rejection rates dropped dramatically, reducing waste and enhancing production flow. Over 80 hours of operation, the plant saved £60.54 in energy costs and achieved an ROI in 29.7 weeks.
The quality control team reported more accurate seal inspections, and the overall efficiency of the inspection stage increased, improving productivity and reducing operational expenses.
Conclusion
These real-world scenarios demonstrate the Spot Dryer’s impact on efficiency, quality, and cost reduction. With 95% energy savings and quick ROI periods, the Spot Dryer is an essential tool for modern production lines looking to optimise processes and achieve long-term sustainability. From pre-date coding and air rinsing to inspection stage moisture removal and sensor maintenance, the Spot Dryer delivers unparalleled performance, making it a valuable investment for any industry.
