4.According to the firing temperature.

Low temperature tunnel furnace, medium temperature tunnel furnace, high temperature tunnel kiln, ultra-high temperature tunnel furnace.

5.According to the firing variety.

Refractory tunnel furnace, ceramic tunnel furnace, red brick tunnel furnace.

6.By heat source.

Flame tunnel furnace, electric tunnel furnace.

Function: The three-layer tunnel furnace is suitable for drying the printing ink on the composite board and acrylic surface.

Second, equipment specifications and main technical indicators.

Conveying method. 1.Three-layer conveying mechanism, round-trip conveying.

2.Automatic deviation correction is used for the anti-deviation of the conveyor network.

3.The inverter is used for stepless speed adjustment, and the speed range is .

4.Fully enclosed gear reducer motor driven.

Structural distribution. 1.External dimension: L9000mm W1500mm H2150mm2Feeding section: 1500mm

3.Heating section: 5000mm (divided into 3 sections, 3 layers of heating section 15000mm in total).

4.Conveyor network from the ground: 1000mm

5.Discharging section: 500mm

6.Turning material and changing layer: 1500mm

Heating method: 1The heating section has a total of 5 meters, and the hot air is circulated to heat the temperature of each section.

2.The PID temperature is adopted, and the phase output control of the SSR component is used to control the temperature quickly and with high stability.

3.The surface temperature of the commonly used material is 80, and the temperature uniformity of the left, middle and right side of the material surface is less than 3 degrees.

4.Furnace set temperature max 120 . Typical temperature 80.

5.The heating section is equipped with rock wool insulation and air insulation, and the surface temperature is 10 times higher than the room temperature.

6.The intake and exhaust dampers can be adjusted to control the micro pressure in the furnace.

7.The front and rear door panels are designed to make maintenance simple and convenient.

8.The furnace adopts the blast circulation and return air mode to reduce heat loss and save energy.

Generally, according to different heat sources, there are electric tunnel furnaces, gas tunnel furnaces or natural gas tunnel furnaces. The manufacturer can customize the length and width according to the production volume of the tunnel furnace user. Scope of use:

Bread (staple bread, prepared bread, etc.), cakes, biscuits, snacks, egg yolk pies, moon cakes, etc. The tunnel furnace is a large-scale equipment that provides continuous baking and can be equipped with a production line. It has the characteristics of high production efficiency, manpower saving, and stable baking quality.

According to the different baking time requirements of various products, intelligent control can be implemented through PLC intelligent control system. Transmission frequency conversion speed regulation, which can realize stepless speed change. And more than 15 groups of parameters can be pre-stored to achieve automatic operation.

UV furnace has portable, drawer, tunnel, only tunnel has a conveyor belt, is a kind of UV furnace, depending on the number of UV lamps, if the UV lamp exceeds 3KW, it is basically a tunnel type. Other forms of fan hot hitting are not required.

UV Tunnel Type:

UV Energy Detection:

Now it's mostly UV cured with UVLED: thank you!

There are several types of tunnel furnaces: UV conveyor furnace, IR conveying furnace, hot tunnel furnace UV furnace is equipped with UV lamp, and IR furnace for ultraviolet curing is equipped with IR lamp inside, which is used for infrared drying.

The hot conveying furnace is equipped with a heating element, which is divided into stainless steel heating pipe and black pipe, which is used for hot drying and the body is based on transportation, but it is not the same.

UV furnaces, UV curing machines, and tunnel furnaces have conveyor belts.

UV tunnel furnace: WKM-1A

UV Tunnel Furnace UV Energy Meter: WKM-UV1

The working principle of tunnel furnace (drying line, Biaowang equipment tunnel drying line) is generally to use far infrared to heat the furnace, and then the interior is made of ceramic and stainless steel, so that the infrared light can shine on every corner of the furnace, and then evenly heat up to transfer energy to the object.

The tunnel furnace is designed and manufactured with foreign advanced technology, with advanced structure, easy disassembly and assembly, and beautiful appearance. The high-tech thermal insulation material has good thermal insulation performance, strong heat preservation, and the heating technology adopts far-infrared heating technology, the heating element is reasonably arranged, and the energy consumption is low. The internal hot air circulation makes the temperature in the furnace more uniform, without loopholes, and ensures the quality of the oven product.
