Abstract:
1. A method of impinging a baked good with treatment fluid, comprising: providing a treatment fluid at a first zone and the baked good to be treated at a second zone, wherein providing the treatment fluid in the first zone elevates the pressure of the first zone; separating the first zone from the second zone with a separation means; providing a passageway of select construction through the separation means for controlling the concentration of the treatment fluid introduced to the second zone; drawing the treatment fluid from the first zone into the second zone through the passageway by difference in pressure between the first zone and the second zone; dispensing the treatment fluid from the passageway into the second zone as a jet, wherein the treatment fluid comprises a mixture of gaseous carbon dioxide and a vaporous preservative; impinging the baked good in the second zone with the jet of the treatment fluid; continuously conveying the baked good through the second zone for being impinged with the jet; and circulating unused treatment fluid from the second zone to the first zone.
