Cardboard Drying Microwave Oven


Description Of Cardboard Drying Oven

Cardboard ovens are machines that dry and cure adhesive-treated corrugated or solid cardboard materials during production. An oven has an enclosed chamber with a heating element that creates hot air within the chamber and a circulating fan that distributes the hot air evenly throughout the chamber. This ensures that the board material is heated and dried evenly, eliminating the possibility of warping, curling or warping. The oven is designed with multiple racks, can hold large quantities of cardboard material, and can operate in temperatures ranging from 50 - 200 degrees Celsius. It also has an exhaust system to help regulate humidity and remove any fumes that may be emitted during curing. Paperboard ovens are essential to the production of high-quality paperboard products, especially those that require high strength and durability. It ensures that the adhesive used to bond the paperboard layers is completely dry, increasing the structural integrity and longevity of the material.

How To Dry The Cardboard

Here are the steps involved in drying cardboard using a drying oven:

  1. Prepare The Cardboard: The cardboard should be inspected to ensure it is free from any foreign debris or other materials that could affect the quality of the finished product.
  2. Load The Cardboard: The cardboard is then placed onto the racks inside the drying oven, ensuring adequate spacing between the sheets for proper airflow.
  3. Set The Temperature: The temperature of the drying oven should be set according to the manufacturer's instructions, usually between 50-200 degrees Celsius.
  4. Set The Timer: The timer on the oven should be set to allow enough time for the cardboard to dry completely. This may vary depending on the thickness and moisture content of the cardboard.
  5. Monitor The Process: During the drying process, it's important to monitor the temperature and humidity levels in the oven. The oven should also be checked periodically to ensure the cardboard is drying evenly.
  6. Remove The Cardboard: Once the drying process is complete, the cardboard should be removed from the oven and allowed to cool before further processing or use.

In summary, a cardboard drying oven is an effective way to ensure the adhesive on cardboard is completely cured, making it stronger and more durable. The process involves loading the cardboard onto racks inside the oven, setting the temperature and timer, monitoring the process, and removing the cardboard once it's dried completely.

Features Of Microwave Drying

Uniform Heating

As microwave acts on water molecules, so the part with high water content absorbs more microwave power than the part with lower water content. This is the characteristic of selective heating, using this feature can achieve uniform heating and uniform drying.

High Efficiency


Energy Saving

Microwave is directly on the role of materials, so there is no additional heat loss, the air in the furnace and the corresponding container will not heat, so the thermal efficiency is very high, the production environment is also significantly improved, compared with far infrared heating can save 30% of electricity.

High Efficiency

Short Time

Because microwave heating does not require the process of heat conduction, so the microwave penetrates the object from different directions into the object inside, from inside to outside so that the material in a very short time to achieve uniform drying, effectively shortening the drying time.

Easy To Control

Compared with conventional methods, microwave operation is easy; microwave power adjustable, adjustable transmission speed.

Advantages Of Cardboard Drying Oven

Faster Drying Time

The drying box eliminates the need to air dry the board, which can take days or even weeks, depending on the thickness and moisture content of the board. The oven dries the board in hours, increasing productivity and reducing overall processing time.

Consistent Drying

The oven provides consistent and even heat and airflow to ensure that the board is dried evenly and consistently throughout. This reduces the risk of warping or deformation and improves the quality of the finished product.

Increased Strength And Durability

Drying the cardboard in an oven ensures that the adhesives used in the cardboard manufacturing process are fully cured. This increases the strength and durability of the cardboard, making it less likely to tear, warp or become damaged over time.

Improve Production Efficiency

 Using a drying oven can shorten drying time and reduce the risk of product damage or defects, thereby increasing production efficiency. This can help businesses save time and money on production costs.

Space Saving

Ovens take up less space than traditional air drying methods, making them a compact and efficient option for businesses with limited space in processing facilities.

Cardboard Product Display

Cardboard is a versatile material that can be used to create a wide range of products. Here are some common cardboard products:


Cardboard boxes are widely used to package products and ship them to various locations. They come in different sizes, thicknesses and shapes to meet various packaging needs.

Display Stands

Paperboard is an excellent material for retail store, exhibition and trade show display stands. They are lightweight, portable, and can print attractive designs and graphics.


Paperboard is also used to make stationery such as file folders, index cards, and binders. These products are durable, cost-effective and can be customized to specific requirements.


Cardboard furniture is a growing trend that offers an eco-friendly and cost-effective option for home and office furniture. Cardboard chairs, tables, and other items are lightweight and easy to assemble.


Cardboard is an excellent material for making children's toys and games. Cardboard puzzles, playhouses, and other toys are fun, eco-friendly, and affordable options.

Arts And Crafts

Cardboard can be used to create a wide range of arts and crafts projects such as picture frames, sculptures and models. These projects are a great way to recycle and repurpose cardboard materials.
