The basic working principle of the tunnel oven

The tunnel oven adopts a long-box hot air circulation and a far-infrared drying method to dry and dry an oven. Mainly for the purpose of high drying and drying requirements for high production efficiency.

The domestic manufacturers have introduced new technologies for digesting foreign advanced technology and newly developed for the water needle and powder needle line of the pharmaceutical factory. They are suitable for drying and continuous destruction of glass containers such as ampoule, vial and oral liquid easy-to-open bottles of various specifications. Bacteria and removal of heat sources. It is an indispensable drying and sterilizing equipment for pharmaceutical companies to implement GMP transformation.

Basic working principle: Under the supervision of the computer system, the bottle enters the preheating zone of the tunnel sterilization oven, the high temperature sterilization zone (temperature ≥5min) and the low temperature cooling zone with the conveyor belt. The conveyor belt speed is steplessly adjustable, and the temperature monitoring system is set to have no paper or paper record. The whole process is always under the protection of 100-level laminar flow.

The tunnel oven heating element is installed at the top of the oven to improve thermal efficiency. The oven is equipped with an electrical control cabinet and temperature digital display control. Can be controlled in any constant temperature state. At the exit, the material can be cooled with a level of cleanliness vertical laminar flow to keep the material in a strictly sterile and dust-free state. Aluminum silicate is used as the heat preservation material in the oven insulation layer, and the heat preservation performance is good.

Tunnel oven structure: The tunnel oven is a continuous drying equipment that can be continuously and continuously baked to improve product production efficiency. The chain is equipped with a chain transmission to solve the phenomenon of deviation during transportation. The oven is segmented and heated, and the independent electric box is controlled and easy to operate.

The tunnel oven structure is mainly composed of two parts: the conveyor system and the drying furnace. Multi-stage independent PID temperature control, uniform temperature inside the furnace. The conveying speed is variable frequency, speed regulation, freely adjustable, stable operation and high production efficiency
