1.8m Length IR Drying Tunnel Conveyor Dryer for Screen Printing

Description

After printing, it must use conveyor dryer screen printing to dry clothes. The purpose of drying is as follows: firstly, it is to prevent color mixing. The second is to make the inks form a strong film to improve the washing fastness. Tunnel dryer screen printing play an important role in garment printing. It directly affects the printing fastness and effect. Therefore, the stability of t shirts conveyor belt dryer is the key to achieving high-quality printing.

What is silk screen conveyor dryer?

It is a kind of continuous infrared mesh belt dryer. Firstly, we put T-shirts and other clothes on the moving conveyor belt. They are sent to the tunnel furnace oven for drying and baking. Then output by the mesh belt. This forms a assembly line. So it improves the productivity and reduce labor intensity. The garment is heated more evenly and fully. Ultimately improve the quality of silk screen printing.

The application of conveyor dryer screen printing: In addition to drying t shirt & clothes, we also use it to bake other products, such as food, glass, electronic components, spray products, paper, etc. Infrared belt conveyor dryer is suitable for the rapid drying of solvent-based inks and the drying of general moisture content items.

How does tunnel conveyor dryer screen printing work?

Compared to other conveyor furnace, tunnel dryer screen printing has similar structure. Conveyor oven printing includes these main parts, such as mesh belt conveyor, heating device, wind supply device and temperature control system.

In printing, we often use eco-friendly water-soluble inks. Therefore, it is necessary to quickly evaporate the water in the ink during baking. So as to achieve rapid drying and curing. The silk screen conveyor dryer uses IR heating tube for drying. It can accelerate the volatilization rate of water and cosolvent. After water absorbs infrared rays, the temperature rises rapidly and evaporates.

The infrared wavelength of heater can match the absorption spectrum of the water-soluble ink very well. Besides, it also matches the absorption spectrum of many textiles. According to the principle of wavelength matching, the molecular resonance of the heated material can be quickly realized. So as to quickly realize the absorption temperature. Ultimately conveyor belt dryer shortens the heating time for clothes.

How does conveyor belt dryer accurately control the temperature? 

The conveyor dryer screen printing is low-temperature baking. The temperature control system composes of AC contactor, thermocouple, temp. control instrument, and heating elements. When the temperature reaches a certain level, the thermocouple detects it. Then transmit the data to the temperature control instrument. The meter feeds back to the AC contactor and informs the contactor to cut off power. That is, it will not continue heating. Otherwise, heating is performed. In short, baking temperature is precisely controlled. The temperature error of conveyor belt dryer can be within ±3℃. So it can ensure the drying quality of printing products.

Technical Specification of Printing Conveyor Oven

Kind note: we can customize the tunnel dryer screen printing as your specific sizes & requirements.

Feature of T Shirt Conveyor Belt Dryer

1. First of all, infrared rays have enough penetrating power for the drying of ink. Therefore, this conveyor dryer screen printing is easier to dry the ink and glue.

2. Secondly, the hot air circulation ensures that the temperature of mesh belt dryer is even and stable. Besides, it makes the printing easier to be completely cured. It not only achieves the purpose of drying, but also protects the toughness of the fabric to the utmost extent. So it prevents clothes discoloration and burning.

3. Thirdly, you can adjust the speed of tunnel dryer screen printing. Besides, the drying temperature is adjustable. Thus, it meets the requirements of the drying time and temp. for different products.

4. Double-layer design of heating zone shell. The internal thermal insulation material isolates the internal and external temperature. It saves energy and protects the working environment.

5. Simple structure. The bracket can be easily disassembled. The heating tube is easy to replace. The mesh belt is durable. So it’s easy to maintain this conveyor belt dryer.

6. The height of the entrance and exit of screen conveyor dryer is also adjustable. Therefore, it can not only prevent the heat from running out, but also meet the high demands of different products.

7. The conveyor dryer screen printing has an exhaust port. It is convenient to discharge the exhaust gas generated during the drying process.

Why use the Teflon mesh belt in the screen conveyor dryer?

We can find that most conveyor dryer screen printing uses the Teflon mesh belt. It is also namely PTFE mesh belt. Because of its below advantages, it is often used in screen conveyor belt dryer.

1. The applicable temperature range is between -70℃ and 280℃. It has weather resistance and anti-aging. After practical application, it can be placed continuously for 200 days at a high temperature of 250°C. Not only the strength will not decrease, but the weight will not decrease. Therefore, it is very suitable for tunnel dryer screen printing.

2. Non-adhesive: It is not easy to adhere to any substance. Easy to clean all kinds of oil stains, ink or other attachments. So you can easily clean the inks on the belt when drying printing products.

3. Chemical resistance. It can resist the corrosion of strong acid, strong alkali and various organic solvents. Silk screen inks contain chemical substances. So it is an ideal conveyor belt for tunnel dryers.

4. Air permeability. The air permeability of the conveyor belt can improve the drying efficiency.

5. In addition, it’s non-toxic. So it’s safe belt material for conveyor belt dryer.

6. Finally, fire and flame retardant.

FAQ

Q1. Which inks can be dried by the conveyor dryer screen printing?
A1. This silk screen conveyor belt dryer can cure most printing inks and glue, such as thermosetting ink & adhesive and water based ink. But for UV ink, it needs the uv curing oven.

Q2. How do conveyor dryer belt replacement?
A2. In fact, similar to other belt conveyors, it easy to replace the mesh belt for printing conveyor oven. When you plan to exchange it, please note the conveying surface. Drag the mesh belt and go around the conveyor roller. The difficulty lies in connecting the conveyor belt. It needs patience. Pass the connecting wire into the hole of the mesh belt, and then fix it.

Q3: Can I use it to dry food?
A3: Conveyor dryer has wide application in food industry. However, the temperature and baking time of this model dryer may not be suitable for food. If you need a conveyor dryer for food, we can also customize it, including microwave tunnel dryer.

Q4: What kind of heating element does this conveyor belt dryer use?
A4. This tunnel dryer screen printing uses the infrared heating lamp. Of course, we can also customize it with stainless steel heater.

Q5: What is the drying temperature and time?
A5. Actually, drying temperature and time of conveyor dryer screen printing base on the specific application. We recommend to perform a drying test before batch baking. To find the best baking temperature and time.
