The status of the technology of drying equipment 

The technology of the drying equipment 

In recent years, with the rapid development of China's industrial and agricultural production, the demand for drying equipment is increasing, and the overall level of drying equipment is improving. Conventional drying equipment can basically meet the needs of production, and some models are exported to foreign countries, the gratifying achievements is the outcome of the general engineering technical personnel long-term efforts, guangdong ruiqi packaging machinery co., LTD., production of dry mainly include: thermostatic oven, hot air circulation drying oven, vacuum drying machine, and mature as technology advances, the progress of the drying equipment in the following aspects: 

Equipment size 

As the unit equipment in production, the dryer is designed to meet the requirements of production. As the scale of production in each industry expanded, the scale of the drying equipment was also increased. At present, the diameter of the flash evaporator machine in our country can reach 1.6 m (not much in this scale), and it works well. Heat transfer area of the blade dryer can reach 160 ㎡, can through a variety of heating medium, disc dryer maximum heat transfer area has reached 180 ㎡. Mechanical centrifugal spray drier capacity can reach 45 t/h, mechanical and electrical integration of centrifugal atomizer also reached the scale of the capacity of 5 t/h, better solve the mechanical problems of atomizer, centrifugal spray drying machine has reached eight meters in diameter, total more than 50 meters high, the processing capacity of 4 t/h. The rotary drum dryer can be 2.5 meters in diameter and more than 30 meters in diameter. The area of belt dryer is more than 140 square meters. 

2. The equipment level 

The equipment level of the drying equipment mainly refers to the control level of the dry system, the equipment of the attached equipment, the ease of operation and the level of safety. The equipment of drying equipment in our country has come a long way. This is especially true of large, dry systems. The main manifestations are in the following aspects: 

The system is equipped with the control system. Automatic and semi-automatic control system is widely used to reduce the labor intensity and the quality of the product. 

The application of computer technology. Most of the large systems use computer technology to collect, process and control system parameters, and make the operating conditions of the system optimal. 

Human design. While designing the equipment, consider the habits of the operator and the ease of maintenance. 

Safety design. The system has safety alarm and dangerous situation, especially the drying of inflammable and explosive materials. 

The ancillary equipment. The auxiliary equipments in the system also tend to be reasonable, heating, feeding, air and solid separation, the packaging equipment of the product and the host relationship to achieve optimization. 

3. The experimental conditions 

Dryer design require specific materials related process parameters, many important parameters must get through the experiment, the design of the dryer are very much dependent on the experiment. So the experimental condition is the key to the accurate design of the dryer. 

Guangdong ruiqi packaging machinery co., LTD., hot air circulation drying oven is intermittent drying generality shelf larger drying equipment, applicable to the pharmaceutical, chemical, food, light industry, electronic industry material of dehumidification and heating. The control cabinet adopts the button control (also can make the touch control according to the user's requirement), the operation is more convenient, prolonged the service life. Most of the hot wind circulates in the box, which is efficient and saves energy. With the effect of forced ventilation, the chamber has a adjustable split board, and the material is dry and even. 

Low noise, running balance, temperature control, installation and maintenance. The inlet can be loaded with the initial effect and the middle effect filter for user's use. We have good after-sales service. We can contact us if we need a friend.
