COMMODITY FUMIGATION PROCESS AND APPARATUS

摘要

Processes and devices for producing a heated non-flammable gaseous fumigant for commodity fumigation use by application of a carrier gas, such as carbon dioxide (102), to a heater (103) either prior or subsequent to mixing the gas with a toxic agent gas, such as methyl bromide (213), such as by means of a mixer (214) and applying the mixture of gasses as a commodity fumigant to eradicate target pests infesting a commodity stored within an enclosed volume (106). In the preferred embodiment, the gaseous carbon dioxide is formed by flashing liquid carbon dioxide (614) directly to the gaseous state in a heater (630) prior to being mixed with methyl bromide (654) in a mixer (648) and applying the mixture of gasses as a fumigant to a commodity held within an enclosure (668).
