摘要： An apparatus and a method for recovering additional expansion agent in a process for the expansion of tobacco or another agricultural product are disclosed. One embodiment is a method for recovering additional expansion agent in a process for the expansion of tobacco or another agricultural product, the process having a multi-step depressurization sequence including at least first and second depressurization steps for depressurizing an impregnation vessel, which includes the following steps: withdrawing substantially all of an amount of an expansion agent in the impregnation vessel at about the end of the second depressurization step during the multi-step depressurization sequence; and transmitting at least a portion of said amount of expansion agent to a low-pressure gas tank. In one embodiment, the expansion agent is carbon dioxide.
