Heat treat furnaces/SIBX-SDIR8500 Powder industrial belt furnace

Scope of application:Food seasoning, feed, chemical industry

conveyor oven with melsh belt dryer/conveyor dryer/conveyor heater/conveyor furnace/heat treatment oven/melsh belt oven

Method of calculating length for tunnel oven

Length of tunnel oven(M)=Material area (m2)*Heating time/width of conveyor belt

Material area=Capacity/ stacking density (kg/m3)/stacking thickness(by our suggest)

conveyor oven is a oven uses a conveyor or belt to carry process parts or material through the primary heating chamber for rapid thermal processing. It is designed for fast drying and curing of products and is nowadays widely used. Normally a conveyor oven adopts a tunnel structure and is composed of multiple controlled zones. A conveyor furnace also features fast thermal responses, uniform and stable temperature distribution; it can heat treated parts to 800 deg. C. (may vary for different model). Belt speed of a conveyor oven can be adjusted to meet customer demands. According to different baking time requirements of various products, intelligent control system can be implemented through PLC intelligent control system. Drive frequency conversion speed regulation, can realize stepless speed change. And can prestore more than 15 groups of parameters, achieve automatic operation.

suitable for baking chemical gas and food processing industry to bake goods, substrate stress removal, ink curing, paint film drying, etc. Widely used in electronics, electrical, communications, electroplating, plastic, metal chemical, food, printing, composite,pharmaceutical, PC board, powder, immersion, spraying, glass, ceramics, wood building materials...... And so on the precision baking, drying, tempering, preheating, shaping, processing and so on.



Hot air circulation and Infrared are the main heating way for tunnel oven.

Hot air circulation is a widely used heating mode of tunnel oven at present. It uses the principle of convective conduction to heat the oven to achieve the drying and curing of the workpiece.

The working principle of infrared tunnel oven is to heat up the furnace by far infrared, and then the interior is made of ceramics and stainless steel, so that the infrared light can shine in every corner of the oven, and then heat up evenly and transmit the energy to the surface of object in short time.


Characterize  Advantages:

Conveyor belt system oven, where the uniform air-flow distribution allows a perfect drying performance along all the tunnel.

Protection device: PID self-setting, automatic constant temperature, automatic timing, timing alarm power off when the temperature arrives, over-temperature power off, leakage protection, motor overload protection, control line fuse, no fuse switch and other electrical accessories;

With intelligent temperature controller, PID automatic calculation, LED display, and SSR solid-state relay output, the accuracy of temperature can be precisely controlled.

The inner liner material is made of mirror 304# stainless steel plate. The argon arc welding can prevent dust from the machine. High temperature powder paint with 2.0mm cold binding plate for enclosure;

The inner cleanliness can reach a level of clean environment

Double over-temperature protection, more reliable safety;

Design the air duct of the oven according to the product features, with good temperature uniformity;

Fast heating time, accurate temperature stability;

Domestic first-class thermal insulation, thermal insulation technology, seal effect remarkable; As we adopted Domestic first-class material of thermal insulation and high-tech of thermal insulation, seal effect remarkable, in another side the oven in double liner, so low temperature of body shell has little effect on indoor environment temperature.

Design of floor trolley or ramp type, greatly reduce on the labor intensity;

Energy and power saving, strong safety performance.


Characteristics of the equipment

1Design according to the proportion of human engineering, easy operation, modern appearance.

2Argon Arc full Welding of all stainless Steel in Inner to prevent dust from the machine itself.

3Unique air-duct designto ensure the temperature inside is uniformity

4First-class technology of heat &thermal insulation, sealing effect is excellent.

5Double over-temperature protection, safer and more reliable.

6Rising up fast, and the temperature is stable and accurate.

7The shell temperature is low, which has little effect on the indoor environment temperature.

8According to the product set up a variety of heating and air mode, energy saving, safety and environmental protection.

9Module designEach section manipulation and operation in flexible independently can be available.

10Colors can be customized base on color card.
