制粒生产线设计中的几个问题

在颗粒饲料生产中，辅助设备同样起着举足轻重的作用。本文关于制粒供料仓的设计、蒸汽锅炉的选择、蒸汽管道的安排、水处理剂的使用、磁选设备的配置等方面的设想和建议，希望引起足够的重视。

论PLC+触摸屏控制技术在饲料制粒生产中的应用探讨

随着科学技术的进步,在各个领域中应用了自动控制技术,其中 PLC、触摸屏等控制技术在饲料生产中具有很强的应用意义, 提高了其生产质量和工作效率。

关于固体制剂制粒技术的研究

固体制剂在药物制剂中占有很大的比重,而且固体制剂相比于其他剂型,有很多优点,因此研究固体制剂制粒技术是非常必要的。我们应结合不同制剂的特点、适用类型及影响因素,不断改进工艺,提高技术水平,采用联线生产方法,应用不同的制粒技术制造出符合国家质量要求的药品。

Fundamental Study on the Production of ＂Hyper Wood Pellet＂——Effect of Torrefaction Condition on Grinding and Pelletizing Properties

In order to upgrade the conventional wood pellet, Japanese softwood and hardwood chips were torrefied at around 200-350℃, and pelletized. The characteristics of the torrefied material/pellets such as their calorific value, grinding energy, pelletizing energy and elemental composition, were also evaluated in this study. The calorific value rose with increasing torrefaction temperature and exceeded 25 MJ/kg （an increase of nearly 40% compared to the untreated state） for torrefaction at around 350℃. The grinding energy greatly decreased with increasing torrefaction temperature, and the reduction was larger for Japanese oak hardwood chips. The pelletization energy for the torrefied material tended to be slightly smaller than in the untreated case. People named such torrefied pellet as ＂hyper wood pellet＂.
