Foam generator

摘要

A foam generator employing a foam generator nozzle that injects compressed air and ambient air into the nozzle body where the air impinges upon a spray of foam liquid within the nozzle body is disclosed. The foam generator nozzle further includes spaced apart first and second fluid dispersion media downstream from the air-liquid mixture to generate a substantially dry foam suitable for application to agricultural crops for frost protection. The method for generating the substantially dry foam is also disclosed.
