FAQ

Q1: What heating methods are commonly used in this equipment?

A:The main heating methods include:

Electric heating (infrared heating / hot air circulation heating)

Natural gas heating

For filter paper drying applications, infrared heating combined with hot air circulation is commonly selected because it can quickly penetrate paper fibers while maintaining uniform temperature distribution.

Q2: How does the equipment prevent lightweight filter paper from being blown away or deformed during drying?

A:The equipment adopts:

Downward air supply or side airflow micro-circulation design

Adjustable airflow speed control

Pressure mesh conveying systems or dedicated fixtures

These solutions ensure that lightweight filter paper remains flat and stable during transportation and drying.

Q3: Can the drying temperature and conveyor speed be adjusted?

A:Yes.The system uses:

PLC control

Intelligent temperature controllers

Frequency converters

for precise temperature adjustment. The conveyor speed adopts variable frequency stepless speed regulation, allowing the equipment to adapt to filter papers with different:

Basis weights

Moisture contents

Material structures

Q4: What is the typical drying temperature for filter paper?

A:The normal drying temperature range is generally 80°C to 150°C.

The actual temperature depends on:

Filter paper material type (such as wood pulp paper or fiberglass paper)

Moisture content

Presence of heat-sensitive resin binders or curing agents

Q5: What safety protection features does the equipment have?

A:The equipment is equipped with multiple safety protection functions, including:

Over-temperature alarm and automatic power cutoff

Conveyor overload protection

Abnormal smoke exhaust interlock control

Conveyor belt deviation alarm

These safety systems ensure reliable operation during large-scale continuous production.

The Filter Paper Moisture Drying Tunnel Oven provides an efficient and stable drying solution for filtration material manufacturers.
