An Horno de secado eléctrico is a device that uses the principle of hot air circulation to dry materials. It is made of high-quality stainless steel, featuring corrosion resistance, high temperature tolerance, and strong durability.
The SL-C series drying oven features an axial fan and an automatic constant-temperature control system, achieving over 95% thermal efficiency. It uses convective heat transfer to warm the air. Fresh air is continuously supplied through the air intake, while moist exhaust air is removed by a dehumidification system. This constant renewal of fresh air and removal of moisture maintains the optimal relative humidity inside the chamber. A key feature of this series is the partial recirculation of hot air within a fully enclosed system, which enhances heat transfer and saves energy.
Shuliy offers five different models of electric drying ovens to meet a variety of drying needs. Each model is thoughtfully designed with a wide loading capacity, handling between 60 kg y 480 kg of material per batch. These ovens are suitable for production lines of different scales and output levels, helping customers achieve efficient and consistent drying results.
Working Principle of the Hot Air Circulation Drying Room
It uses a high-temperature circulating fan to force hot air—heated by electric heating tubes or a steam heat exchanger—to circulate inside the chamber. The circulating hot air fully contacts the material, carrying away moisture from its surface. The dehumidification and exhaust system then discharges the moist air, and the drying process continues until the material reaches the preset drying standard.
La estructura del horno de secado.
The equipment is composed of a box, a hot air circulation system, a heating system, an electrical control system, a dehumidification system, a drying trolley, and drying trays etc.
caja principal
The box is an integral structure, and the fan and control cabinet are in the upper right corner of the box. The appearance is made of acero inoxidable placas y está pulido con precisión. Todo el equipo tiene una apariencia hermosa, una estructura confiable, no se deforma y es especialmente fácil de limpiar. La capa aislante del cuerpo de la caja está hecha de algodón aislante de basalto, que tiene las ventajas de tener poca influencia en la temperatura ambiente del taller durante el trabajo, buen efecto de aislamiento térmico, baja pérdida de calor, ahorro de energía y menor consumo.
Sistema de calefacción
The heating method adopts electricity, steam, natural gas, and multiple heating methods. The element adoptsa stainless steel fin heat exchanger, which has fast heat transfer and a superheats exchange area, which improves the working efficiency of the whole machine and prolongs the use time of the equipment.
Sistema de circulación de aire caliente.
Para aumentar la cantidad y el volumen de circulación de aire caliente en la caja y mejorar la uniformidad de la temperatura en la caja, se instalan dos ventiladores de circulación en el lado derecho de la caja. El ventilador adopta un proceso de equilibrio dinámico para garantizar una rotación de alta velocidad sin vibraciones ni ruidos. Todas las esquinas de la caja adoptan una estructura de arco circular, que no solo puede evitar que el aire caliente forme rincones muertos sino que también aumenta el volumen de aire.
Sistema de deshumidificación
Se instala un ventilador deshumidificador de 0,37 kw en la salida de aire y el arranque y la parada se controlan mediante un medidor de control de temperatura y un relé de tiempo. La compuerta se abre automáticamente cuando se enciende el ventilador húmedo y se cierra automáticamente cuando se detiene.
sistema de control eléctrico
The temperature adopts PID automatic control, an automatic alarm for over-temperature, and stops heating at the same time. All low-voltage electrical components are of well-known brands. The complete set of electrical control systems has a high degree of accuracy, stable working performance, concise and intuitive operability, and long service life, which provides a favorable guarantee for the normal production of users.
Carro y bandeja para hornear
Equipado con un carro de acero inoxidable, según el tamaño estándar de 710 × 950 × 1390 (mm), 12 capas, el carro está equipado con ruedas de nailon resistentes a altas temperaturas y resistentes a la corrosión. Cada carro tiene las características de estructura firme, operación flexible, apariencia hermosa y fácil limpieza. Cada vagón está equipado con 48 bandejas de acero inoxidable. Las especificaciones unificadas de las bandejas son 460×640×45 (mm). Están formados por estampado de una sola vez, con una apariencia hermosa, sin ángulos agudos y de alta resistencia.

Purchase Considerations for Stainless Steel Drying Oven
1. Confirm the Heating Source
Choose a suitable heating method—such as steam, heat transfer oil, electric heating, or far-infrared—based on your production conditions, and ensure the site can supply the required energy source.
2. Specify Temperature Requirements
Clearly state the desired operating temperature range. If the required temperature is above 140°C or below 60°C, inform the supplier in advance for non-standard customization.
3. Match Capacity and Size
Select the dryer size and number of layers according to your daily drying output, and confirm the quantity and specifications of trays and trolleys.
4. Select the Control System
Choose between an automatic control system or a PLC computer control system according to your automation needs and operator skill level.
5. Material and Thickness
Confirm the stainless steel grade (e.g., 304 or 316) and plate thickness. Thicker plates cost more but offer better durability and longer service life.
6. Installation Space and Conditions
Ensure that the installation site meets the equipment size, ventilation, and moisture exhaust requirements, with extra space reserved for maintenance.
8. Safety Features
If the drying process involves flammable or explosive materials, opt for an explosion-proof model and confirm the required explosion-proof rating.
