缩短坯子的干燥周期,提高干燥效率的方法是很多的,如改变自然干燥为人工干燥是比较现代化的一种干燥方法,也是提高干燥效率的一种最有效的方法。但是,采用人工干燥需要较大的投资,对我国目前情况来说,要在制砖工业中大量兴建隧道干燥室或更现代化的电气干燥、高频电波干燥设备是有困难的,所有这些只能作为我国砖瓦工业今后发展的方向,逐步地过渡到现代化的生产水平。目前,最切合实际的是研究如何在现有的条件下,在节约国家投资的前提下改进干燥方法来达到提高干燥效率的目的。
There are many ways to shorten the drying cycle of the billet and improve the drying efficiency. For example, changing the natural drying to artificial drying is a more modern drying method, and it is also the most effective method to increase the drying efficiency. However, the use of artificial drying requires a large investment. For the current situation in China, it is difficult to build a large number of tunnel drying rooms or more modern electric drying and high-frequency wave drying equipment in the brick making industry. As the direction of China’s brick and tile industry in the future, it will gradually transition to the modern production level. At present, it is most practical to study how to improve the drying method under the existing conditions and save the country’s investment to achieve the purpose of improving the drying efficiency.
