In the food processing industries, medicinal herbs, agricultural products, etc., drying raw materials plays an extremely important role. Understanding that need, Vnatech is proud to introduce to customers a line of modern and advanced industrial electric drying oven products, helping to optimize production processes and improve business efficiency.
What is an industrial electric drying oven?
An industrial electric drying oven is a device that uses electricity to generate heat, used in the drying and heat treatment processes of materials and products in industrial environments. This oven allows adjustment of temperature, drying time, and other parameters to ensure the quality and efficiency of the production process.
Structure of industrial electric drying oven
Industrial electric drying oven has a complex and detailed structure to meet the needs of drying and heat treatment of materials and products in industrial environments. Below is a more detailed description of the structure of an industrial electric dryer:
Furnace Frame and Shell
The furnace frame is usually made of stainless steel or heat-resistant steel, ensuring high durability and the ability to withstand high temperatures without deformation. The kiln frame has a sturdy design to support the entire structure of the kiln and its internal components. The furnace shell is made of heat-resistant and well-insulated materials such as stainless steel, with a thick insulation layer to retain heat inside the furnace and protect the operator from high temperatures outside. The insulation is usually ceramic fiber, glass wool, or other insulation materials to minimize heat loss.
Heating part
The resistor (Heater) is the main part that converts electrical energy into heat energy. These resistors are often made from Nichrome (nickel-chrome) alloy due to their high heat resistance and good durability. The resistor can be a bar, coil, or plate, arranged so that heat is evenly distributed throughout the furnace. Thermal coils or heating rods are designed to withstand high temperatures and maintain stable heat transfer over long periods.
Fan and ventilation system
The circulating fan system ensures even circulation of hot air throughout the oven, helping the temperature in the oven to be uniform and optimize the drying process. Fans are usually made from heat-resistant metal and are designed to operate effectively in high-temperature environments. The ventilation duct system helps maintain a continuous airflow, eliminating moisture released from the drying material. Filter elements may be included to keep dust and other small particles out of the environment.
Control system
The temperature controller uses automatic control devices such as PID (Proportional-Integral-Derivative) to set, monitor, and adjust the temperature inside the furnace. A digital display or LCD screen allows the operator to easily monitor and adjust temperature. The timer allows setting the drying time according to the specific requirements of each type of product or material. The timer can automatically turn off the oven when the drying process is completed. Helps save energy and ensure safety. Temperature sensors are placed in many locations in the oven for measurement. Monitor temperature, and ensure the drying process takes place according to set parameters.
Rack or drying tray
A drying tray or rack is used to place products or materials that need to be dried. The tray is removable and easy to clean. Usually made from heat-resistant metals such as stainless steel or aluminum. Guaranteed durability and heat resistance.
Security system
The safety switch automatically cuts off power when overheating is detected. Or there is an unusual incident to protect users and equipment. May include limit switches and thermal cutoff switches. The thermal fuse protects the oven from overheating. Cutting off the circuit when the temperature exceeds the allowable limit, prevents the risk of fire and explosion.
Disinfection or toxic gas removal system
For industries that need to ensure high hygiene such as food and pharmaceuticals. Can be equipped with a disinfection system using UV rays or ozone gas. For materials that emit toxic gases when drying. Can be equipped with an air filtration system or toxic gas exhaust pipe.
Principle of operation
The operating process of an industrial electric dryer begins with converting electricity into heat through resistors or heat bars. This heat is transferred to the space inside the furnace. The circulating fan distributes heat evenly throughout the oven, helping to dry products evenly. The control system monitors and adjusts the temperature according to settings. Ensure the drying process is efficient and stable. The ventilation system removes moisture generated from the drying process. Make sure the air in the oven is always in an optimal state for drying.
Industrial electric dryers with detailed structure and operating principles as above ensure the ability to dry and process materials effectively, stably, and safely in an industrial production environment.
Advantages of industrial electric drying oven
In general, dryers have much higher efficiency than residential dryers. Because it is specifically designed to serve industries. Or certain foods. If your business scale is large and product quality requirements are strict, you can consider choosing dryer lines that suit your production needs.
The advantages of industrial food drying ovens can be listed as follows:
- Preserves intact color and flavor of ingredients. Almost intact compared to fresh products before drying.
- The drying time for one batch is short. The dehumidifying system quickly removes water from the product. Limit heat loss.
- Big size. Suitable for industrial drying scale. Each drying batch is about 500kg – 1 ton of fresh ingredients.
Can be designed flexibly. Depending on the customer’s needs and product characteristics. - Reasonable price. Helps reduce capital costs for dried products.
- Can be used for a variety of foods. Such as agricultural products, seafood, medicinal herbs… Materials that need to be dried at high temperatures such as paint drying, glue drying, mold drying, wood…
- Use high technology. Helps reduce power consumption.
- Diverse drying trays. Can be easily changed and adjusted according to customer requirements.
Application of industrial electric drying oven
Industrial electric drying ovens are widely used in many fields such as:
- Food industry: Drying agricultural products, processed foods, and herbs.
- Chemical and pharmaceutical industry: Drying of raw materials, intermediate products, and finished products.
- Wood and paper industry: Wood drying, paper before processing or use.
- Textile industry: Drying fabrics and fibers before further processing.
