This system comprises the coffee bean roaster provided with the bean roaster 50, the fan 54 for sucking the exhaustion gas from the roaster, the centrifugal separator for dusting the exhaustion of the fan, the filtration type dust collector 62 for collecting the dust from the dusted exhaustion and the deodorizer 15 for deodorizing the exhaustion after dust collection and with the cooler 10. The cooler 10 forms the airtightly closed cooling space with the air-tight structure of the cooling tank 14, the dust collector 12, the cooled air generator 11 and the cooled air-circulating paths 13 that is shut out of the atmosphere and linking these apparatuses. of the air-tight structure.
