Solutions or Products Featured
in This Case Study

Key Reasons for Implementation

  • The pneumatic spray nozzles stably sprayed a small amount of fine fog.
  • Prompt on-site testing allowed the customer to confirm its performance.
  • Its compact design, just over 40 mm in length, made it easy to install even in tight spaces.
  • A proven track record with other food processing machine manufacturers reinforced its selection.
  • Compliance with the Food Sanitation Act ensured it met industry standards.
  • Not sure which product is right for you?
  • Curious about the total cost?
  • Wondering where to start?

Challenges Faced by the Customer

At a beverage manufacturing plant, single-serving coffee creamer cups were disinfected with hydrogen peroxide before filling. However, the pneumatic spray nozzles from another supplier produced coarse droplets, leaving white spots on the containers due to incomplete evaporation of the liquid, resulting in defective products.

Attempts to increase the air pressure for finer atomization were limited by the low-volume spray design, which restricted further increases in liquid pressure. When the air pressure exceeded 0.2 MPa, the liquid pressure fell behind, leading to unstable spraying and hunting.

Proposals from IKEUCHI

The ultra-compact pneumatic spray nozzle SCBIM Series was selected, specifically the SCBIMV 005 model, which has the lowest flow rate in the series.
A sample was brought to the site, and an on-site test was conducted directly on the production line.
As predicted from the performance data chart, no hunting occurred even when the air pressure was increased to 0.3 MPa, and stable spraying (of 4cc/min) was confirmed.

Benefits Achieved

The nozzle complies with the Food Sanitation Act, and its ease of use was highly praised by other line managers who participated in the testing, paving the way for its adoption in other processes as well.
