Production technology of edible vinegar-containing dry paper towel

The invention relates to a production technology of dry paper towel and especially relates to a production technology of edible vinegar-containing dry paper towel. The production technology comprises the following steps of adding edible vinegar with a concentration of 3-5% into a vinegar storage tank, carrying out filtration by a nanometer water purification filter in the vinegar storage tank to obtain nanometer vinegar with particle sizes of 10-40nm, conveying the nanometer vinegar into a heating tank, heating the nanometer vinegar at a heating tank temperature of about 120 DEG C to obtain vinegar vapor, separating water vapor in the vinegar vapor by a vapor-water separation device so that the vinegar vapor is transformed into edible vinegar dry vapor with humidity less than or equal to 10%, feeding the edible vinegar dry vapor into a nozzle in a spray case, conveying dry paper towel subjected to sterilization into the spray case, uniformly spraying the edible vinegar dry vapor to upper and lower surfaces of the dry paper towel and carrying out packaging to obtain a finished product. The production technology has the advantages of less production processes, small equipment investment and popularization easiness.
