Product Introduction 
The Curved Rapid sheet dryer employs a curved, integrated heating plate to generate uniform thermal radiation. The wet handsheet is placed on the plate surface and secured with a stainless steel mesh cover. The curved profile allows the sheet to maintain intimate contact with the heating surface while steam vents freely from the mesh side, achieving rapid and uniform drying. A precision temperature controller allows the user to set and hold the desired temperature up to 180°C, preventing over-drying or under-drying. Used in tandem with a standard sheet former, it completes the laboratory papermaking and sample preparation system.

Key Features 
Curved Heating Plate Design The integrated curved heating plate simulates the industrial dryer cylinder surface, accommodating the natural shrinkage profile of paper sheets to prevent curling, cockling, and distortion during drying.
Precision Temperature Control Adjustable up to 180°C with automatic constant-temperature maintenance, allowing optimal drying conditions for sheets of different grammages and pulp types.
Rapid Steam Venting A stainless steel mesh cover holds the sheet in place while allowing steam to escape quickly, preventing moisture-related surface defects.
Single-Side Glazed Drying The sheet dries with one side against the heated surface and the other against the mesh, producing flat, curl-free specimens at a fast drying speed.
Compact Benchtop Footprint Dimensions of 800×550×320 mm; lightweight and space-saving for easy placement and movement within the laboratory.
Simple Operation & Maintenance-Free Four-step operation: place the sheet, close the mesh cover, set the temperature, and start heating. The maintenance-free design reduces operational costs.
Universal Test Compatibility Dried sheets are immediately suitable for subsequent brightness, thickness, smoothness, tensile strength, and other physical and optical evaluations.
Efficient Energy-Saving Heating 2500 W power combined with a large 400×500 mm curved plate delivers high thermal efficiency, rapid heat-up, and shorter experiment turnaround times.

Main Technical Specifications

FAQ
1. What advantage does the curved dryer have over a conventional flat plate dryer?
The curved heating plate emulates the arc of an industrial dryer cylinder, better matching the natural shrinkage of paper during drying. Combined with single-side glazed drying, it significantly reduces curling, cockling, and distortion—especially for heavy-grammage or high-shrinkage sheets.

2. How do I set the drying temperature? What temperature is recommended for different sheet types?
Set the target temperature via the thermostat dial or digital panel. Generally, lightweight sheets dry well at 100-120°C, while heavier board grades may require 150-180°C. Specific settings should follow your laboratory SOP and pulp characteristics.

3. How long does it take to dry one standard handsheet?

Drying time depends on grammage, initial moisture content, and set temperature. Typically, a standard φ159mm sheet dries within 3-5 minutes at 150°C. Thicker, heavier sheets will require longer drying cycles.

4. How do I clean and maintain the dryer after use?
Allow the heating plate to cool completely, then wipe the surface with a dry cloth to remove fiber residue or water spots. The stainless steel mesh cover can be rinsed with water and air-dried. The unit is maintenance-free; no periodic part replacement is required. Keep surfaces clean.

5. Can it be used to dry non-paper materials?
The dryer is primarily designed for standard pulp handsheets. However, any wet sheet-like material that requires flat, rapid drying and is compatible with stainless steel can potentially be processed. A small-scale trial is recommended to confirm suitability.

6. Can dried sheets be tested immediately for mechanical properties?
No. Dried sheets should be conditioned in a standard atmosphere (e.g., 23°C and 50% RH) for at least 4 hours before physical and optical testing to ensure moisture equilibrium and data accuracy.
