试验结果表明,对湿地松松脂加工,要达到国家标准的松香,不能沿用马尾松松脂的加工工艺,而应采用直接火滴水法加工。加工时火力要猛,滴水量要大;保温温度应控制在165～175℃;保温时间以35～40min为宜;放香温度控制在185℃左右,不要超过190℃,避免树脂酸高温氧化使松香变红降级。 The test results show that for the processing of pine resin of P. elliottii, it is necessary to use the direct fire drip method to process rosin to meet the national standard. Firepower to be fierce processing, the amount of dripping should be large; insulation temperature should be controlled at 165 ~ 175 ℃; holding time to 35 ~ 40min is appropriate; aroma temperature control at 185 ℃, not more than 190 ℃, to avoid the resin acid oxidation Rosin red downgrade.
