An 电烘干箱 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 和 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.

主箱
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 不锈钢 板并经过精密抛光。整套设备造型美观，结构可靠，不变形，特别容易清洗。箱体保温层采用玄武岩保温棉，具有工作时对车间环境温度影响小、隔热效果好、热损失小、节能低耗等优点。
加热系统
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.
热风循环系统
为了增加箱内热风循环的数量和风量，提高箱内温度的均匀性，在箱体右侧安装了两台循环风机。风扇采用动平衡工艺，保证高速旋转无抖动、无噪音。箱体内各个角落均采用圆弧结构，既可以防止热空气形成死角，又可以增加风量。
除湿系统
出风口处安装0.37kw除湿风机，启停由温控表和时间继电器控制。湿风机开启时风门自动打开，停止时风门自动关闭。
电气控制系统
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.
手推车和烤盘
配备不锈钢手推车，按照标准尺寸710×950×1390（mm），12层，手推车配备耐高温、耐腐蚀尼龙轮。每台手推车均具有结构牢固、操作灵活、造型美观、清洗方便等特点。每辆车配备48个不锈钢托盘。托盘统一规格为460×640×45（mm）。采用一次冲压成型，外形美观，无尖角，强度高。

Product Advantages
Corrosion-Resistant, Heat-Resistant, and Long Service Life
Made entirely of high-quality stainless steel with a smooth and hygienic surface, the dryer offers excellent rust and corrosion resistance. It is easy to clean and maintain, with optional thickened steel plates for enhanced durability. The service life can reach up to 10 years or more.
Uniform Drying and High Yield
The efficient hot-air circulation system ensures even temperature distribution inside the chamber, allowing materials to be heated uniformly. This results in stable drying quality, excellent product appearance, and a significantly higher yield rate.
Energy-Saving and Eco-Friendly
The hot-air circulation design maximizes heat utilization, minimizes heat loss, and reduces energy consumption, while also lowering environmental impact.
Easy Operation with Intelligent Control
Equipped with an advanced PLC intelligent control system, the dryer features an intuitive interface for quick setting of temperature, time, and other parameters. Fully automated operation reduces the need for manual intervention.
Wide Range of Applications
Suitable for the food, pharmaceutical, chemical, and electronics industries, meeting high hygiene and performance standards across multiple sectors.
Precise Temperature Control
The dryer is equipped with a high-sensitivity temperature control system and intelligent sensors that monitor temperature changes in real time. It automatically adjusts the heating power to ensure that temperature fluctuations are kept within ±1°C.
Explosion-Proof Design
Both the interior of the drying chamber and the electrical control system feature explosion-proof designs. Key components are equipped with explosion-proof motors, explosion-proof lamps, and explosion-proof control elements, effectively preventing explosion risks in high-temperature and high-humidity environments.
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.
