Our Customers

Pure and Natural Food Consortium

The  CoolSteam Pasteurization is an all-natural method that maintains the quality and integrity of the cashews, macadamia nuts, and pecans we are currently running through the line. Our operations team has found the equipment to be very user-friendly. The recording and built-in monitoring of vital elements of the process instills great confidence that the equipment is meeting or exceeding performance expectations.
