At present, in the sales of domestic drying Syringe Mould Manufacturers, economic drying equipment accounts for about 50%, meeting the domestic market demand; popular drying equipment accounts for about 45%, achieving large-scale production; * type drying equipment accounts for about 5% The variety has increased greatly; the economic drying equipment has reached the capacity of bulk export, the popular drying equipment has gradually expanded its exports, and the export of * type drying equipment has made a breakthrough.
It is understood that according to the special planning requirements for drying equipment development, by 2015, domestic drying equipment will account for more than 50% of the domestic market demand, complete functional components, self-sufficiency rate of 60%, and systems with independent intellectual property rights account for drying equipment. 75% of total production.
Realize the industrialization of key functional components, lay the foundation for the upgrading of drying equipment products; develop high-precision digital measuring instruments and tools, and support the medium* drying equipment; implement the *type drying equipment demonstration project to meet the needs of national key projects.
To become the main body of technological innovation, enterprises should be connected with universities and scientific research units in various forms to rationally allocate and utilize resources, effectively cultivate and develop their innovative capabilities; and continue to reform and open up policies. Introduction and absorption; new capabilities cannot be introduced, and it is necessary to expand the combination of technology and trade and accelerate independent innovation. Innovation, introduction, digestion, absorption, transformation, and independent innovation can not be less.

The operation flexibility is large and the applicability is wide. Many drying factors of the drum dryer can be adjusted. For example, the concentration of the feed, the thickness of the coating film, the temperature of the heating medium, the rotation speed of the drum, etc., can change the drying efficiency of the drum dryer, and many factors are not involved. This brings great convenience to the drum drying operation, so that it can adapt to the drying of various materials and different production requirements.
Short drying time. The drying cycle of the material is generally only 10-300 seconds, which is suitable for heat sensitive materials. If the drum dryer is placed in a vacuum, it can be operated under reduced pressure.
The drying rate is large. Since the coating film is thin on the wall of the cylinder, it is generally 0.3-1.5mm, and the heat transfer and mass transfer directions are the same. The surface of the film can maintain the evaporation of 20-70kg.H2O/m2.h.
Vacuum drum dryers operate in a similar manner, but using low temperatures may damage the food from extreme heat. The drums of this type of drying equipment are sealed inside the vacuum chamber and are considered expensive in view of the form of dewatering. Drum drying represents a more efficient method of dehydrating food.
HZG series rotary drum dryer
After the wet wholesale Syringe Blister Packaging Machine is put into one end of the dryer, the material is evenly distributed and dispersed in the dryer under the flipping of the inner tube, and the material is fully contacted with the cocurrent (countercurrent) hot air to accelerate the drying heat transfer. Passed to the driving force. In the drying process, under the action of the inclined plate and the hot air flow, the material can be adjusted to the other side of the dryer to discharge the finished product.
