Drying equipment is widely used in pharmaceutical, chemical and other industries. At the same time, with the continuous improvement of industrial production technology level and consumer requirements, higher technical requirements are also put forward for drying equipment. The application of drying equipment in petrochemical enterprises is very common and serves petrochemical enterprises. Therefore, it is greatly affected by the industry economy. This year, the overall economic operation of the petrochemical industry is not optimistic, which is a challenge to the drying equipment industry. It is the small companies that are really hit hard. The large companies have not been greatly affected. Some large companies have only narrowed their profit margins, and their output value has not declined.
For example, microwave vacuum drying equipment is a new type of microwave energy application equipment that combines microwave energy technology and vacuum technology. It combines a series of advantages of microwave and vacuum drying, and overcomes the shortcomings of conventional vacuum drying cycle and low efficiency. In the drying process of general materials, the work efficiency can be increased by 4 to 10 times compared with conventional methods. It has the advantages of high drying output, good quality and low processing cost. The microwave vacuum drying equipment is a high-tech product integrating electronics, vacuum, mechanics, thermodynamics, program control and other disciplines. It is in the drying process. Based on the in-depth study of the physical changes of substances, internal and external heat and mass exchanges, and the process of moisture migration under vacuum conditions, a new technology and new process have been developed.
The technological content of the drying equipment has initially shown a leading role. Since 2004, driven by the continuous improvement of the national chemical development situation, the market situation of the drying equipment is stable and optimistic, and production companies have generally achieved good operating results. At present, the distinctive feature of the drying equipment serving the chemical industry is the increasingly prominent role of technical content. This is very different from the past when selling products mainly by price competition. Among them, some manufacturers of high-tech drying equipment, focusing on the development of new products, the benefits are increasing; on the contrary, some companies with low product technology content, new products and new technology development capabilities, the benefits began to decline.
After more than ten years of development, at present, China's drying equipment industry has begun to enter a more mature stage, which can better meet the actual needs of users in various fields. In view of the "green" advantages of vacuum drying equipment, it is increasingly used. In terms of food and medicine drying, the demand for larger vacuum drying equipment will gradually increase, and the market prospect is very huge.
Experts said that when exploring a new development path for drying technology, comprehensive consideration must be given to energy efficiency, environmental protection, and product quality in order to achieve comprehensive, coordinated, and sustainable development. To implement the development strategy of high efficiency and green drying, we must first take the path of resource-saving development, and transform single extensive drying into combined and intelligent drying. Not only the fundamental transformation of the drying process, but also a comprehensive and multi-level energy-saving technological transformation, and the vigorous development of the application of renewable energy and industrial waste heat drying technology.
Compared with the commonly used oven drying method and spray drying method, the vacuum continuous drying method has many unique advantages, which can ensure that the product quality is much higher than the products using other drying methods. Vacuum continuous drying equipment and technology have the advantages of low temperature drying, less damage to active ingredients, loose and easily soluble absorption, drying and sterilization, so as to ensure high effective ingredients, high sterility index, and good oral absorption.
Industry insiders pointed out that domestic companies have accelerated the research on vacuum drying technology, and some companies have made breakthrough progress, which has reduced energy consumption and pollution to a certain extent, and brought more benefits and value to society.
Although there is still a certain gap in the domestic production of drying equipment compared with developed countries, it is gradually establishing the advantages of domestic equipment and basically achieving the dominance of the domestic market. Vacuum drying equipment will become the mainstream of market demand, and the domestic industry must greatly improve the technical level, improve the drying efficiency, reduce energy consumption, and contribute to the realization of green production.
The Polypropylene Joint for Plastic Infusion Container is made of the imported medicalâ€class polypropylene; where the material complies with FDA rule and passes the USP CLASS VI test. Beneath the joint, itis a shipâ€shape, which will form a plastic liquid infusion bag after welding with nonâ€PVC coâ€extruded film; the top opening is the inlet for loading liquid medicine. After filling the liquid medicine, the top opening will be melted to seal with the composite cap, and then form a complete softâ€bag liquid infusion product. The joint is produced in the clean plant, with the overall plant reaching to Class 10,000 and some for Class 1,000,000. The main working procedures, such as the injection molding, inspection, cleaning, inner packing and so on, are designed and processed as per the cleanliness requirements at the partial level of Class 100 , which passes the GMP onâ€site certification and complies with the cleanliness requirements of high capacity injection medicine.
The surface of production equipment is smooth, flat, and easy to clean and sterilize, with sound corrosionâ€resistant property, and inert to make chemical reaction with packing material. The precision and sensitivity of test and inspection instruments comply with the test and inspection requirements of products.
The polypropylene joint for plastic infusion container is mainly used for the pipe of nonâ€PVC softâ€bag.
