Summary

Propeller fans are widely used in various food production lines. However, only little knowledge is available for the effective cooling of food products using a low-efficiency propeller fans. It is well-known that propeller fans make a highly turbulent flow which can improve the efficiency of heat transfer. This suggests that the propeller fans potentially performed an effective cooling of food products despite of their low fan efficiency if a highly turbulent flow is achieved. In this article, we attempted to obtain detailed data about the characteristics of air flow from propeller fans and the efficacy of heat transfer. The results showed that the maximum flow velocity was found to be high at a position near the propeller fan. Moreover, the flow velocity profile showed a large difference in the vicinity of the propeller fan; whereas, the opposite tendency was found in the farther distance position from the fan.
