Prior to the reform and opening up, drying equipment was mainly imported from Japan, Europe and the United States. In 1980, the first dry equipment manufacturing enterprise of the nature of collective ownership was opened in the Yangtze River Delta region where China's first township chemical company was born. It is supposed that in the Yangtze River Delta where the economy is relatively developed, after more than 30 years of development, there should be several large-scale enterprises in the field of drying equipment manufacturing.
However, although the total number of companies in Changzhou City, the most concentrated drying equipment manufacturing company, is as many as 1,300, only a few companies with annual sales revenues of more than 100 million yuan are rare, and only a few old companies have achieved unprecedented results in 2008. Over 100 million yuan in sales revenue, and only once before and after. Other better companies sell 50 million to 60 million yuan a year, and the average company is about 20 million yuan. The local private chemical companies that developed during the same period did not have dozens of sales revenues of several billion yuan a year.
Why is the difference so obvious? The key is that the industry's entry threshold is too low, and 500,000 yuan plus 10 mu of land will be able to build a drying plant. Some registered companies actually did not even have a formal factory site. After negotiating on the basis of relationships and means, they immediately took a grass-and-mortar team, recruited raked metalworkers and welders, and rented factories to start producing dryers. This practice is not uncommon in Changzhou. This phenomenon is called scattered.
People in the industry believe that in order to expand the drying equipment enterprises, it is necessary to improve the industry's access threshold, and the establishment of national standards is an important part.
It is reported that at present, there is no national standard in the domestic drying equipment manufacturing industry, that is, the industry standard only involves a small number of products. The quality of many products is only the final word of the customer, and the industry calls it the “standard guestâ€. An independent device manufacturing industry, with no national standard and no industry standards, cannot objectively verify the quality of drying equipment.
