一、泡沫酸脱绒 脱绒棉种的质量决定能否进行包衣和大田应用的价值,因此,脱绒要加强三方面的管理。 1、泡沫酸脱绒机运行的控制。 烘干机进口温度一般为150～165℃,出口温度65℃左右。种子从喂入到摩擦机出口停留时间控制在40分钟左右,最长不超过45分钟,以防种子在高温区停留时间过长而影响种子发芽率。 2、种子残酸率的控制。据试验,残酸率0.2％ First, the foam acid plush fleece cotton quality decide whether the coating and field application of the value, therefore, to velvet to strengthen the management of the three aspects. 1, foam acid velvet machine running control. Dryer inlet temperature is generally 150 ~ 165 ℃, the outlet temperature of about 65 ℃. The feed from the feed to the friction machine outlet dwell time control in about 40 minutes, the longest no more than 45 minutes to prevent the seeds in the high temperature zone residence time is too long and affect the seed germination rate. 2, the control of seed acid rate. According to the test, the residual acid rate of 0.2%
