Heating and Drying Oven

Description

Climatest Symor® heating and drying oven is made of stainless steel, and has a double-walled chamber with insulation in between to prevent heat loss. The samples are placed for drying or curing on the shelves. The temperature and time settings can be adjusted depending on the required heating conditions.

Specification

Working principle

Heating and drying oven adopts hot air circulation, or forced air convection system within the oven. The oven is designed in a way that ensures the hot air is evenly distributed throughout the chamber.
When the oven is turned on, a heating element, usually located at the bottom or the sides of the oven, begins to heat up. As the element gets hotter, it heats up the air inside the oven. This hot air then rises and circulates throughout the chamber, drying the samples or specimens placed inside.
The oven also has fans or blowers that help circulate the air more quickly and evenly, which ensures that the samples are dried uniformly. A temperature controller is used to regulate the temperature inside the oven and prevent overheating.
The heating and drying oven has a timer that allows the user to set the drying time required for the particular samples or specimens. Once the set time has elapsed, the oven turns off automatically.
Overall, heating and drying oven is a simple but effective instrument to dry various materials in laboratories and industries.

Structure

A heating and drying oven typically consists of the following components:
• Exterior oven: Made of cold rolled steel plate with varnish baking on surface, with insulation layer.
Interior oven: Made of stainless steel SUS#304, providing sturdy structural support, which is resistant to high temperatures and corrosion.
• Heating Element: Generating heat inside the oven.
• Blower: The fan circulates the hot air inside the oven to ensure even hot air distribution.
• Temperature control system: Consists of a thermostat, thermocouple, and temperature sensors that measure the temperature inside the oven. It is used to maintain a constant temperature and prevent overheating.
• Timer: Set heating time, once the set time elapses, the oven turns off automatically.
• Shelves: Hold samples, height is adjustable to accommodate samples of different sizes.

Overall, the structure of Climatest Symor® drying and heating oven is simple but highly effective for baking various materials. The different components work together to ensure that samples are heated or dried uniformly and efficiently.

Application

A heating and drying oven is often used in research laboratories to dry and cure samples before analysis, to evaporate solvents from samples, or to heat samples prior to conducting tests or experiments.

Morever, drying oven is also used in industrial settings to dry electronic components (Printed Circuits Boards), and cure coatings, adhesives, and other materials, here let’s illustrate how a drying oven is used in SMT industry:

SMD package may get damp due to climate reasons, long-term storage or improper storage, the moisture inside the package will vaporize and expand due to reflow soldering heating, this may cause damages, like wiring disconnection, or reduced reliability, this is called the "popcorn" phenomenon.

In J-STD-033 standard, it suggests SMD packages can be baked at 125 deg C to recover their floor life, the baking time differs as per MSL/package body thickness. The drying oven is the optimal choice, it provides different temperature baking from 50 deg C to 125 deg C, and effectively expel moisture from MSD packages, this greatly helps manufacturers to improve production efficiency, and avoid the huge loss of products recall due to substandard quality.

What causes a heating and drying oven overheat?

There are several reasons why an oven may overheat, including:

•Malfunctioning thermostat: The thermostat is responsible for regulating the oven temperature. If it's faulty, it may not accurately read the temperature, resulting in the oven heating up beyond the set temperature.

•Broken heating element: The heating element provides the heat needed for cooking or baking. If it's broken, it may continue to generate heat even when the oven is turned off, causing it to overheat.

•Blocked air vents: The air vents are necessary for proper air circulation in the oven. If they're blocked, the heat will remain trapped inside, causing the oven to overheat.

•Damaged door gasket: The door gasket seals the oven door tightly and prevents heat from escaping. If it's damaged, heat may leak out, causing the oven to overheat.

Overall, it's important to regularly maintain your oven and address any issues as soon as they arise to prevent overheating and to ensure safe operation.

Frequently asked questions

Q: What is a heating and drying oven?

A: A heating and drying oven is used to heat materials or dry them out to remove moisture. It is typically used in industrial settings to dry out parts, components, and materials. Additionally, they may be used to cure materials or to temper them.
