1 设备选型 1.1 包衣机的密封性目前国内生产的种衣剂多含呋喃丹等高毒农药,人体摄入过多导致中毒。特别是对种子包衣相继投入使用,更加大了这种危险性。国内现有机型密封性能尚不十分理想,一般选用离心式雾化系统和自流式供药系统要安全些;国外一些种子加工厂对包衣机采取单独隔离措施,大大减少药
1 Equipment Selection 1.1 The sealing of the coating machine At present, the domestic production of seed coating containing carbofuran and other highly toxic pesticides, lead to excessive human intake of poisoning. In particular, the seed coating have been put into use, even greater the danger. Sealing performance of existing domestic models is not yet very satisfactory, the general choice of centrifugal atomization system and gravity for the drug delivery system to be safe; some foreign seed processing plants on the coating machine to take a separate isolation measures, greatly reducing the drug
