Introduction of case studies for problem-solving: "Scrubber"

No pump needed! Energy-saving wet dust collector "Scrubber"

There was a competition to develop new products for a bento factory, and one of the factories developed a device to actually grill meat over charcoal for a new charcoal-flavored bento. There was a problem where a large amount of smoke and sparks were generated when the meat was grilled, and the mission was to propose a device to eliminate that. To solve the problem, we used a scrubber test machine to actually suck in the smoke and confirm its effectiveness. This revealed the following issues: 1. Airflow: If the suction is too strong, the smoking effect is reduced, and the meat does not acquire the charcoal flavor. 2. Sparks: If sparks adhere to the oil in the duct, there is a possibility of causing a duct fire. 3. The scrubber body becomes hot, posing a risk of burns. We solved these problems using the following methods and confirmed their effectiveness: 1. Airflow: We adjusted the airflow to a level where smoke filled the hood of the charcoal grilling machine but did not overflow outside. The smoke did not leak outside, and the charcoal smoking effect on the meat was optimal. 2. Sparks: By passing water through the scrubber, we were able to effectively extinguish the sparks. 3. We installed a burn prevention plate at the entrance of the scrubber body. Thanks to our efforts, our scrubber was adopted.
