Analysis of Development of Spray Drying Technology in China

In recent years, with the development of the national economy, the improvement of people's requirements for the quality of life, many products not only require their drying, but also their color, aroma, taste and reconstitution properties (cold or instant). ), vitamin activity retention rate, etc. put forward higher requirements for the total yield of some valuable drugs is also very harsh. These requirements are the requirements of the international market for our country after entering the WTO. The following summarizes China's new device developed in the field of spray dryers in response to the requirements of the objective market. The common feature of these devices is that instead of using a single spray dryer as a commercial product, a spray dryer is used as the core, and according to the characteristics of the materials, other drying devices or auxiliary equipment combined drying equipment systems are used to make their final products meet User needs. In addition, the basic trend of large-scale, high-strength, high economical, and spray dryer development to improve the adaptability of raw materials and product quality. At the same time, the development of spray dryers should pay attention to the comprehensive utilization of energy-saving and energy, as well as the development of dryer automatic control technology, in order to ensure the realization of the best operating conditions. In addition, as a human being attaches great importance to environmental protection, improved spray dryers to reduce dust and exhaust gas leakage environmental protection measures will also be studied in the depth direction.

The research and development of spray drying technology and equipment for ceramics in China began in the late 1970s. The use of 2000-type pressure spray dryers in industrial production began in the mid-1980s, and now domestic spray dryers for ceramics industry have national standards. And serialized. Over the years, the world’s ceramics industry has debated the development of two kinds of technical processes, namely, spray drying mechanism powder and direct dry milling of materials. The relevant government departments have also established projects for the dry process project and organized the results identification. At present, the spray dryer is one of the most widely used dryers in a large number of drying apparatuses, and is a drying apparatus for treating a solution, a suspension, or a muddy material. The ability to dry directly from a liquid into a powder is the biggest advantage of a spray dryer; its disadvantages include low thermal efficiency, bulkiness, low productivity, and high investment. Spray drying has the special advantages of powdered products which can be directly obtained from the solution or suspension system. It is currently widely used in the chemical, light industry, food and other industries. The dye industry is the most widely used in the chemical industry.

At present, China's dry products have begun to enter a more mature stage of development, and can better meet the actual needs of users in various fields, and in the price only 1/3 of the same foreign products, which makes China's drying equipment in the market competition than imports The equipment has obvious price advantages. On the other hand, due to the large volume of drying equipment, most of them involve on-site installation, commissioning and after-sales service. Therefore, for domestic users, it is more convenient to use domestic equipment than to use imported equipment. In the international competition, the main competitors of China's drying equipment manufacturers are Denmark, Switzerland, the United Kingdom, Germany, the United States, and Japan. Compared with competitors, the advantages of drying equipment in China are low prices.

This machine is applicable to the twisting, preshrinking and false twisting of the polyester filament yarn. The crepe yarn is used as raw material for the silk-like polyester fabrics.
 
 
1. This machine is allowed to produce crepes of different styles according to the raw materials of different fineness, providing the fabric producers with a new platform and condition in the products development.
 
2. The machine has the following features such as high efficiency, high output, low cost, quick turnover and convenient management.
 
3. Digital monitoring-----spindle speed, number of false twist spindle, overfeed rate, winding speed, length of meter, alarm display, working time, program memory, twist direction etc.
 
4. The machine adopts PLC control, which can adjust the twist freely.
 
5. This machine is really the first choice in supporting the raw material depended on processing enterprises and textile factories to perfect their equipment.
