In the printing industry, achieving professional results isn't just about having the right ink and the right machine. In fact, the most critical stage that determines the true quality of the print is the final product. drying and fixing It is a process. And this is exactly where... conveyor dryer(also known as fixation tunnelThis is where conveyor dryers come into play. Used in every field from textile printing to screen printing, DTF and DTG applications to the packaging industry, these systems increase production speed, ensure quality standards, and make the print much more durable. As of 2025, the vast majority of professional workshops are still switching from classic heat gun or infrared systems to conveyor dryers, increasing production quality several times over.

The biggest advantage of conveyor dryers is that they remove the ink from the printing surface. by heating in a controlled manner hem sabitlemesi hem de yüzeydeki olası solvent veya su bazlı nemi tamamen uzaklaştırmasıdır. Bu kontrollü fikse, özellikle tekstil baskılarında boyanın çatlamamasını, akmamasını ve yıkamaya dayanıklı olmasını sağlar. Serigrafi baskıda “baskı çatlıyor”, “renk akıyor”, “baskı mat görünüyor” gibi sorunların %90’ı doğru kurutma yapılmadığında ortaya çıkar. Konveyör kurutucu tam olarak bu sorunları ortadan kaldırmak için geliştirilmiş bir sistemdir.

For professional businesses, conveyor dryers are not just equipment, but also... increasing production efficiency It is an investment tool. For example, drying a t-shirt with a manual hot air gun takes about 20-30 seconds, while in a conveyor dryer, this process takes place in seconds depending on the belt speed. Moreover, a standard temperature profile is applied to all products. This both reduces product return rates and increases customer satisfaction. If you are setting up a screen printing workshop or want to expand your existing line, the conveyor dryer is the central machine that forms the "core" of the process.

To understand the working principle of a conveyor dryer, it is necessary to first look at the basic components of the system. These machines generally consist of a motorized belt, high-heat resistors, an insulated tunnel, a temperature control unit, a belt speed adjustment system, and cooling fans. The belt is usually heat-resistant Teflon It is made from a material that can withstand temperatures up to 250–280°C, so it does not deform during long-term and uninterrupted use. The material used in our product... Teflon tape with grid pattern resistant to 270 degrees., It ensures a long lifespan and trouble-free performance.

The ability to adjust the conveyor belt speed using a "Danfoss speed control drive" is one of the significant advantages offered by these devices. This allows users to slow down or speed up the belt according to their needs. For example, water-based screen printing inks require longer fixation times, while plastisol inks cure faster at higher temperatures. Speed adjustment is essential, especially for different textile types (cotton, polyester, blended fabrics), as the heat profile varies.

In addition, temperature control Emko digital temperature controller This ensures complete control for printers. A constant temperature profile is maintained inside the tunnel each time the product passes through. If you set the temperature to 150°C, that temperature will remain stable without fluctuation; this prevents negative effects such as burning, glare, or discoloration on the print surface. Especially in textile printing where quality is demanding, this type of stabilization is fundamental to professional production.

Located at the outlet of the dryer 4 fan cooling sections This is another important technology that increases the speed of the production line. After the print exits the tunnel, the surface is still hot. If the product is folded or stacked immediately, the print can stick, deteriorate, or become glaring. These fans blow ambient air onto the product as it exits the tunnel, allowing the print to stabilize quickly. This allows products to move much faster to boxes, hangers, or other processing steps. This significantly increases production speed.

Another strength of conveyor dryers is... energy efficiency. The insulated tunnel structure prevents heat from escaping. This ensures the device maintains the set temperature continuously without unnecessary energy consumption. With energy costs rising by 2025, workshops are increasingly turning to more energy-efficient systems instead of low-cost products. Conveyor dryers perfectly meet this need.

Beyond the screen printing industry, conveyor dryers are rapidly finding new applications. They are preferred in powder curing after DTF printing, in curing water-based inks in DTG printing, and even in special prints on glass and metal surfaces. Therefore, this machine should be considered not just "screen printing equipment," but also a "multipurpose industrial drying system." For this reason, as printing workshops grow, they often invest in conveyor dryers as one of their initial projects.

When looking at the trends for 2025, especially Automation systems that speed up production Its popularity is increasing. Manual desktop dryers are now suitable for small-scale amateur users, but are insufficient for professional businesses. A workshop that prints between 100 and 500 prints a day absolutely needs a conveyor dryer. This shows that the product is indispensable not only in terms of quality but also in terms of production capacity.

One of the most frequently asked questions during the conveyor dryer purchasing process is, "What should the belt length and width be?" This is because belt width directly affects the capacity of the production line. For example, in a t-shirt printing business, a narrow belt can hinder the easy placement of products. Our product features ideal dimensions for optimum use. These dimensions ensure practical use for both small workshops and medium-sized manufacturers.

Sometimes, users setting up new workshops mention problems like, "My printing temperature isn't high enough, the print is cracking." Most of these problems actually stem from improper heat management. A conveyor dryer addresses this need by balancing the heat and preventing potential printing problems. Moreover, because the heat is distributed homogeneously throughout the tunnel, the product doesn't come out overcooked while other parts are undercooked. This is a fundamental criterion for professional production.

How Does a Conveyor Dryer Work? Technical Details, Heat Management, and Correct Use.

Understanding a conveyor dryer correctly is the first step to using it properly and achieving maximum efficiency. For businesses operating in screen printing, DTF, DTG, and textile production, drying processes are directly related to print quality. To efficiently use a professional machine like a conveyor dryer, it's necessary to understand both the system's logic and its technical components. In this section, we will explain in detail the working principles of a conveyor dryer, heat distribution, the effect of belt speed on printing, the physical changes occurring within the tunnel, and common usage errors.

The conveyor dryer's operating process basically consists of three stages: heating phase, fixing phase and cooling phase. When these three stages are combined with the correct timing and parameters, perfect curing occurs on the printing surface. Products passing through the tunnel are heated in a controlled manner according to a predetermined temperature, the water or solvent in the paint completely evaporates, the binders on the printing surface are activated and fully fixed by the effect of the heat. If the product is removed before this process is complete, the print will crack, differences in gloss will appear in dark areas, waviness will be seen in water-based paints, and plastisol prints will begin to dissolve during washing.

1. Heat Management and Heat Profile Inside the Tunnel

The most critical factor determining the success of a conveyor dryer is..., heat homogeneity inside the tunnelIn poorly designed, inexpensive dryers, one part of the tunnel overheats while other sections remain low. Such devices are known in the market as "quickly failing, burning the print." In a professional dryer, however, the heating elements are evenly distributed across specific areas of the tunnel, and the temperature control unit constantly receives feedback to maintain a constant temperature. This is particularly critical for plastisol curing in the 150–170°C range, as deviations from this temperature seriously affect print life.

Used in our conveyor dryer model Emko temperature control device, It can control the temperature in the tunnel with a precision of 1 degree. This means that when set to 150°C, it provides a stable temperature between 148–152°C without fluctuations. Stable temperature ensures even curing of all areas of the product, especially in large-area prints (T-shirt back designs, sweatshirt chest prints, bag prints, etc.).

2. Why is Band Speed So Important?

The drying process is not solely dependent on heat. It also... how long the product remained in the tunnel This is also a determining factor for print quality. This is where belt speed comes into play. If the belt moves too fast, the product cannot heat up sufficiently; if it moves too slow, the print may be damaged. Therefore, speed control is essential for professional businesses. Our product includes... Danfoss speed control drive, This allows for very precise adjustment of the belt speed. Thus:

• For water-based screen printing, the tape can be set more slowly, allowing the water to evaporate completely.
• For plastisol printers, production can be accelerated by slightly increasing the conveyor belt speed.
• For heat-sensitive fabrics like polyester, the tunnel temperature is lowered and the tape is slowed down to allow for gentler curing.

For a print to be properly fixed, heat and speed complement each other. To understand this, let's look at this example: If a product needs to remain at 150°C for 40 seconds, the conveyor belt speed must be adjusted according to the tunnel length. If the belt is too fast, this time will be reduced to 20 seconds, and the fixing process will be incomplete. This is why the combination of "heat + time" determines the fate of the print.

3. Advantages of Teflon Tape Structure

In conveyor dryers, belt material is one of the most critical issues. Low-quality belts loosen, yellow, begin to tear, and deform over time due to heat. However, the quality of the belts used... Teflon tape with grid pattern resistant to 270 degrees., It maintains its durability even with prolonged use. Thanks to its grid structure:

• Heat penetrates better into the product,
• The moisture underneath the product evaporates faster.,
• The belt cools down faster,
• Energy efficiency increases.

This structure also prevents products from sliding on the conveyor belt and ensures a more stable transfer.

4. The Contribution of Fan Cooling Systems to Production

Although the product exiting the conveyor dryer is cured, its surface is still hot. Due to this heat, the product should not be folded immediately. However, since production needs to be fast, the products must stabilize as soon as possible. Therefore, a sealant is placed at the exit of our product. 4 high-efficiency fans, It quickly removes heat from the product. This provides the following advantages:

• The product is stacked faster,
• Glare or ghosting is prevented in printing.,
• The products do not stick together.,
• Üretim hızı %30’a kadar artar.

This fan system is especially invaluable for businesses that produce 200–500 units per day.

5. How to Achieve Energy Efficiency?

By 2025, energy costs will become a decisive factor in the manufacturing sector. Therefore, it's not enough for the machine to simply print well; it needs to consume low energy. The energy efficiency of a conveyor dryer is ensured through the following details:

• Insulated tunnel structure, It prevents heat from escaping.
• Digital temperature control, It prevents unnecessary energy consumption.
• Grid-patterned Teflon strip, This allows the system to run less, by cooling down faster.

Bu özellikler, elektrik tüketimini klasik ısı tabancası kullanımına göre %40–60 azaltır.

6. Which Printing Types Is This System Most Suitable For?

Conveyor dryers are the ideal drying solution not for a single printing technique, but for almost all modern printing systems:

• Screen printing water-based prints
• Screen printing plastisol prints
• DTF printing powder fixing
• Water-based ink curing in DTG printing.
• Post-UV printing reinforcement
• Bags, textiles, hats, and cotton-polyester blend products.

This diversity means the device is not actually a "print tunnel," but a full-fledged one. industrial drying line This is an indication of that.

7. Most Common Mistakes When Using Conveyor Dryers

Although professional equipment operates according to sound principles, user errors can reduce print quality. The most common mistakes include:

1. Using an unnecessarily low temperature
2. Greatly increase bandwidth.
3. Stacking the product on top of each other immediately after passing through the tunnel.
4. Insufficient fixation in white ink prints.
5. Overcrowding the tunnel

Every error in printing actually stems from an incorrect establishment of the relationship between heat and time.

Conveyor Dryer Buying Guide: Which Model Should You Choose?

Purchasing a conveyor dryer is a critical investment that directly impacts your workshop's speed, print quality, and production capacity. Choosing the right model requires considering not only the technical specifications but also your business's production structure, the types of printing used, and the daily output volume. In this section, we will discuss in detail which conveyor dryer is suitable for which type of business, the standard quality criteria that a dryer should meet, the future needs of production lines, the lifecycle costs of the machines, and the new advantages offered by 2025 technology.

A professional conveyor dryer is not just a "heating machine"; it's a central hub managing the production line. Every detail, from the resistance structure and insulation inside the tunnel to the belt width and speed control, determines the fate of the print. Especially with water-based and plastisol prints, if the heat profile isn't managed correctly, products can open, crack, or develop a dull/faded appearance during washing. Therefore, every business should ask itself these questions before purchasing:
“What is my daily production quantity?”, “Which inks do I use?”, “Do I print on materials other than textiles?”, “How important is my energy cost?”, “Will I increase my production in the next 2 years?”

1. How to Choose the Right Conveyor Dryer According to Your Business Type?

Not every workshop has the same needs. A startup might print 50-100 copies a day, while medium-sized manufacturers work with 200-600 copies. In large-scale production workshops, daily print runs exceed 1000 copies.

For small-scale printing workshops:

• Narrow-band, medium-sized tunnel models are ideal.
• For businesses that do desktop printing, large models can create unnecessary electricity costs.

For medium-sized printing workshops:

• Models with a wide tunnel structure and high thermal stability are recommended.
• Speed control is critical in workshops switching between water-based and plastisol solutions.

For large manufacturers:

• Models with long tunnels and double resistance lines, suitable for continuous production, are more appropriate.
• Energy efficiency and service life are far more important.

The choice of conveyor dryer also depends on your workflow. For example, if a business uses desktop printing presses for high-speed production, the dryer needs to have a large conveyor belt width. Otherwise, the product sequence will be disrupted and the belt will clog.

2. Essential Features of a Conveyor Dryer

The most important technical criteria to consider when purchasing a conveyor dryer are:

• Temperature stabilizing digital thermostat (e.g., Emko)
• Speed control device (e.g., Danfoss drive)
• Teflon tape resistant to 270 degrees.
• Insulated tunnel structure
• Fan cooling outlet
• Low energy consumption
• Easy maintenance.
• Belt adjustment with tensioning drum.

These features determine both print quality and extend the life of the machine.

3. The Effect of Conveyor Dryers on Print Quality

There are three main factors that determine print quality:
heat – time – stability.
If these three elements are not properly adjusted, the following will be seen in the print:

• Opening during washing
• Cracking
• Pale appearance
• White inks appearing powdery
• Incomplete curing in plastisol.
• Surface irregularities in water-based paint.

All of these problems are eliminated when the correct conveyor dryer is used.

Conveyor dryers also to make the colors look more vibrant, extending the life of the print And increasing customer satisfaction This is why many businesses prefer to upgrade the drying system first, rather than the flat printing machine.

4. The Effect of Conveyor Dryers on a Company's Production Line

The use of conveyor dryers changes the production flow in the following way:

• Small workshops start operating 3–4 times faster.
• Medium-sized businesses can achieve a printing capacity of 300–700 copies per day.
• On major lines, the system becomes suitable for automation.
• Products are packaged faster.
• Baskı hataları %60 azalır.
• Labor costs decrease.

Therefore, the dryer is considered the "heart pump" of the business.

5. Areas of Application and Compatibility

Conveyor dryers can be used not only in t-shirts but in many different areas:

• Bag prints
• Hat prints
• Metal plate prints
• DTF powder fixative
• DTG water-based ink drying
• Children's clothing prints
• Polyester sportswear
• Cotton products
• Canvas bags

In terms of compatibility, it integrates with almost all printing systems.
