以全钢子午线轮胎带束层胶的混炼为例,探讨GK255型密炼机上压砣控制系统的改进效果。结果表明:上压砣由气压控制系统改为液压控制系统后,炼胶压力稳定,胶料门尼粘度减小,胶料密度均匀性和炭黑分散等级相当,成品轮胎耐久性能均有所提高;省去胶料三段混炼工序,可缩短混炼时间,提高生产效率,节约生产成本。 相似文献

Continuous Manufacture of Enzyme-Containing Washing Agents Owing to their operational and commercial advantages, aggregates like air-lift and mixing sections are attaining increasing significance recently in the manufacture of washing powders as against the spraying tower, which uptil a few years back solely determined the property of the finished product. As shown by the author, considerable progress has been achieved recently in the manufacture of modern non-dusty and easily soluble products in this field. During the manufacture of such items, a separation of the individual powdery components and a mixing up of different products from the starting point up to the blending stage must be prevented. 相似文献

Quality Control of Sea-Frozen Fish in the Modern Fish-Industry Attempts have been made to show the importance of elaborate controlling machines in the manufacture of deep-frozen products from sea-frozen material (filet pieces from Jackstone vertical frosters). In order to direct the entire production from the viewpoint of food hygiene and economy, the quality control is accomplished in the ?Nordsee”? starting right from processing of fish and fish parts on the board itself (board control). The series of controlling operations are carried forth with repeated recheckings (using statistical and analytical methods) of the various processing steps (control steps), e. g. landing of sea-frozen material (discharge control), low temperature intermediate storage (control at intermediate production stage), manufacture of the corresponding finished product (control at production stage), and finally despatch of the deep-frozen product to the customer (control during storage of the finished product). 相似文献

随着计算机技术的不断普及,用计算机控制生产过程已越来越引起各行各业的重视。单片机作为最典型的嵌入式系统。已被广泛的应用到各种类型的工业控制中。将单片计算机控制技术应用于生产线上,实现生产过程的自动控制,同时通过对工业现场的生产情况进行监控,达到加强管理、提高产品质量、提高生产效率、降低劳动强度的目的,是当前企业生产控制管理的发展趋势。在乳粉生产过程中乳粉干燥是乳粉生产中一个重要工序,它直接关系着乳粉的成品质量。利用单片机根据排风温度调节变频器的频率控制进奶量。从而来控制乳粉的干燥过程.其控制要比常规的人工控制方便、准确,而且对于提高乳粉的干燥质量、提高劳动生产率具有实际意义。 相似文献

Margarine and margarine oil,formulation and control 总被引:4,自引:0,他引:4
Lars H. Wiedermann 《Journal of the American Oil Chemists' Society》1978,55(11):823-829
The formulation and control of margarine and margarine oils is based primarily on an understanding of the relationships between
specific physical measurements and the compositions of the oils blends and their components, and secondarily, on an appreciation
of processing effects, Desirable solids-to-liquid ratios are achieved by blending and hydrogenation control. Oils are chosen
for their peculiar crystal habit resulting from conditions of processing both as oils, for components, and as a finished margarine
product. This presentation identifies the underlying principles directly responsible for (a) proper formulation and control
to achieve desirable finished product characteristics, (b) for choosing proper testing methods and (c) for developing adequate
in-process controls. 相似文献
