PURPOSE: Sinner equipment having a non-circulating duct system is provided to prevent the inside of a spinner from being contaminated and to extend a life cycle of a chemical filter by exhausting the air exhausted from the lower portion of the spinner by an exhaust duct. CONSTITUTION: A spinner(17) and an air conditioning system(3) are prepared. Air filtered from the air conditioning system is supplied to the spinner by the first duct(4). Air exhausted from the spinner is exhausted to the atmosphere by an exhaust duct(16). An ammonia density in the air inside spinner equipment is maintained.
