(12)All parts of equipment are made of high quality microwave electric components:
A. It use 110 pieces of water cooled magnetrons which is original Korea Samsung [model OM75P] (rated power 1050 w), good cooling effect, and the distribution of magnetron is sparse, the heat dissipation space is large.
B. It adopts special transformer WBL-1000A with overheating protection (high voltage 100 kv transformer, high quality transformer for full copper core 8.0 kg of a real transformer industry).
C. The specifications of ultra-high voltage capacitor is (1.05 uf 2500 v) and more stable and durable than the conventional (1.0 uf 2300 v) performance.
D. (CL04-12) high-voltage silicon stack (its chip is made in Japan), the reverse repetitive peak voltage can reach 12kv, positive commutation current is 450mA, and checked by practice, durable, entirely suitable for microwave equipment.
E. Adopt the 518mm cabinet design process.The microwave output use PTFE board and special material sealing.Equipment positive with visual observation window to prevent microwave leak, facilitate to observe material and cleaning, in order to ensure the safety of operator, design especially a automatic power-off protection device when open the door.Stainless steel pipe materials, easy disassembly and cleaning, distance is about 250 mm.Outside the web use the 1.0 mm (±0.2 mm) full stainless steel material, it is beautiful and generous.
F. Transmission system:
b.The transmission line form, size, material and function is durable and not wandering.
(13)Wet removal system:The equipment is set up 11 wet mouths at the upside .Need to install 3 sets high pressure low speed centrifugal fan to remove the wet, and can reduce the temperature of the material to ensure better drying effect, strengthen removing wet at the bottom of the material.
(14) In order to ensure the uniformity of material in the drying process and dry effect, and especially adopt the wide body, low microwave density way design, more conform to the requirements of the material characteristics of the drying and low temperature drying process.
The machine set up a separate console on discharging suppressor to make the switch operation convenient (using Siemens PLC man-machine interface touch screen automatic control system).it can control the power of the whole machine, transmission speed, heating temperature control.(including transport system, wet removal system, temperature display system, electrical work).
On the top of the microwave heating box section 11, install raytek infrared temperature control system is a set of each, one set.Monitor and automatically control of material in the process of heating drying temperature.To prevent material temperature too high to effect the material quality.
