Hello River Brand Heat Pump Paper Tube Dryer Starts a New Journey

Spring returns to the earth, and everything is updated. Jin Aoyuan starts a new journey in the new year. In February 2023, Hello River Brand paper tube drying equipment based on heat pump technology provided equipment upgrade and installation services for cooperative customers. After running the machine to test the paper tube drying, the customer is very satisfied with the operating efficiency and energy consumption data of the paper tube drying equipment.

Paper tube paper tube is a tubular object processed from paper, most of which are spiral paper tubes and seamless paper tubes. Paper tubes are ubiquitous in daily life and are widely used, such as paper tape, toilet paper tubes, food paper tubes, chemical fiber paper tubes, polyester paper tubes, industrial spinning paper tubes, etc. In the process of paper tube production, there is an important link, which is the drying of the paper tube

In the past, the production of paper tubes mostly used traditional drying methods - electric heating and drying, which had the following problems:

1. The heating temperature is too high. Traditional drying techniques make it difficult to control the heating temperature. The general heating temperature is around 75-90 ℃, while the paper tube drying process requires that the drying temperature should not exceed 70 ℃.

2. the uneven drying temperature caused by electric heating results in the burning of the paper tube near the electric heating, while the paper tube far from the electric heating has not been dried yet, resulting in an excessively long drying time.

3. High energy consumption. Traditional drying processes have low thermal efficiency, ranging from about 30% to 60%. During the drying process, the heat of evaporated moisture during drying accounts for about 36%, the loss of exhaust gas accounts for about 58%, the heat carried away by dry materials and the heat loss of the dryer account for 2% and 2%, respectively, with a thermal efficiency of only 40%.

4. There are safety hazards, as unstable temperature control often leads to fires.

Our company has been deeply involved in the field of heat pumps for many years and has accumulated rich project cases in industrial drying. The paper tube dryer with air energy heat energy uses air energy heat pumps for heating, utilizing a small amount of electrical energy to make the compressor of the heat pump dryer work. Through the refrigerant in the system, it completes the conversion of absorbing heat energy from the air to the drying room to release heat energy.

Paper tube drying process:

1. Temperature: The temperature for drying the paper tube should be set according to the thickness of the paper tube, generally around 55 ℃~70 ℃.

2. Humidity: In terms of moisture removal, it mainly refers to the adhesive used for bonding during the production of paper tube lamination, so the moisture content in the paper tube is not high. Controlling moisture removal can save energy consumption.

3. Drying time: According to factors such as the diameter, thickness, and adhesive properties of the paper tube, the general drying time for the paper tube varies from 4 to 10 hours.

4. Straightness/roundness: During the drying process, it is necessary to control the axial and radial deformation of the paper cylinder.

5. Hardness/strength: This is an important indicator of the quality of the paper tube.

The characteristics of Hello River Brand air energy heat pump paper tube dryer:

1. Low energy consumption;

2. Adopting a reasonable air distribution design, the drying time is shorter (the drying time for each batch of paper tubes varies from 4 to 10 hours).

3. Advanced control system; Adopting full touch screen control, the interface operation is simple, and the process parameter setting is convenient.

4. The drying process is fully automated and does not require dedicated personnel to guard it.

5. The production environment is hygienic and free from open flames.
