220V Small Tunnel Oven

The 220V Small Tunnel Oven is a continuous thermal processing equipment that uses 220V household power supply or single-phase industrial electricity. It continuously transports materials through a conveyor system and performs heating, drying, baking, or curing processes.Due to its compact size, low power consumption, and easy operation, it is widely used in laboratories, small-scale factories, and low-volume production lines.

Core Applications

Electronic Components Industry

Used for:

PCB board curing

Adhesive drying after dispensing

Reflow soldering of surface-mounted components

Fine Chemical Industry

Used for surface drying and thermal curing of products made from:

Plastics

Rubber

Resin

Other polymer materials

Food Processing Industry

Used for continuous baking of small-batch food products, including:

Biscuits

Nuts

Snack foods

Other baked products

Pharmaceutical and Medical Industry

Used for:

Applicable Standards

This type of equipment generally needs to comply with the following national and international standards:

GB/T 10067.1 / GB/T 10067.4

Basic technical requirements for industrial electric heating equipment and indirect resistance furnace standards.

GB 5226.1

Safety of machinery — Electrical equipment of machines — General technical requirements.

CE Certification

For export to Europe, the equipment should comply with:

Low Voltage Directive (LVD)

Electromagnetic Compatibility Directive (EMC)

Equipment Features

Single-Phase Power Supply

Uses a 220V power supply, eliminating the need for additional industrial three-phase power (380V). It supports convenient installation and plug-and-use operation.

Continuous Production Operation

Uses mesh belt or chain conveyor transmission. Materials enter and exit in a first-in-first-out process, providing much higher efficiency than traditional batch ovens.

Precise Temperature Control

Usually equipped with PID intelligent microcomputer temperature control combined with solid-state relays (SSR), achieving temperature control accuracy of approximately ±1°C.

Space Saving Design

Compared with large industrial tunnel ovens, the overall length and width are significantly reduced, making it suitable for:

Desktop layouts

Small workshops

Laboratory environments

FAQ

Q1: What maximum temperature can a 220V tunnel oven achieve?

A: The standard design temperature range is usually from room temperature up to 250°C or 300°C.

If temperatures above 400°C are required, customized high-power heating elements or a 380V power supply are generally needed.

Q2: What is the typical power rating of this type of oven? Are special circuit breakers required?

A: The power is generally between 2 kW and 6 kW.

The working current is approximately 10A–30A. It is recommended to install a dedicated 16A or 32A circuit breaker. Using a standard household socket is not recommended due to possible overload risks.

Q3: Can the conveyor belt speed be adjusted?

A: Yes.

The equipment is usually equipped with a frequency converter or speed-regulating motor. The conveyor speed (for example, 0.1–1.5 m/min) can be continuously adjusted through the control panel to meet different heating and drying time requirements.

Q4: Can the length and width of the tunnel oven be customized?

A: Yes.

Although it is a small-scale tunnel oven, the following parameters can usually be customized according to material size and production requirements:

Drying chamber length

Inlet height

Mesh belt width (commonly 200 mm–400 mm)

Q5: What heating methods are used? Will temperature differences occur inside the oven?

A: Common heating methods include:

Far-infrared heating

Quartz heating tubes

Hot air circulation heating

The equipment is usually equipped with internal air circulation motors to improve temperature uniformity throughout the chamber, preventing uneven heating, local overheating, or material burning.
