An Elektrischer Trockenofen 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 Und 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.
Der Aufbau des Trockenofens
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.
Hauptbox
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 Edelstahl Platten und ist präzise poliert. Die gesamte Ausrüstung hat ein schönes Aussehen, eine zuverlässige Struktur, keine Verformung und ist besonders leicht zu reinigen. Die Isolierschicht des Kastenkörpers besteht aus Basalt-Isolierbaumwolle, was die Vorteile eines geringen Einflusses auf die Umgebungstemperatur der Werkstatt während der Arbeit, einer guten Wärmeisolationswirkung, eines geringen Wärmeverlusts, einer Energieeinsparung und eines geringeren Verbrauchs bietet.
Heizsystem
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.
Heißluftzirkulationssystem
Um die Anzahl und das Luftvolumen der Warmluftzirkulation im Kasten zu erhöhen und die Gleichmäßigkeit der Temperatur im Kasten zu verbessern, sind auf der rechten Seite des Kastens zwei Umwälzventilatoren installiert. Der Lüfter nutzt einen dynamischen Auswuchtprozess, um eine Hochgeschwindigkeitsrotation ohne Jitter und Geräusche zu gewährleisten. Alle Ecken im Kasten haben eine Kreisbogenstruktur, die nicht nur verhindern kann, dass die heiße Luft tote Ecken bildet, sondern auch das Luftvolumen erhöht.
Entfeuchtungssystem
Am Luftauslass ist ein 0,37-kW-Entfeuchtungsventilator installiert, und Start und Stopp werden von einem Temperaturkontrollmesser und einem Zeitrelais gesteuert. Die Klappe öffnet sich automatisch, wenn der Nassventilator eingeschaltet wird, und schließt sich automatisch, wenn er stoppt.
Elektrisches Steuersystem
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.
Trolley und Backblech
Ausgestattet mit einem Edelstahlwagen, entsprechend der Standardgröße von 710 × 950 × 1390 (mm), 12 Schichten, ist der Wagen mit hochtemperaturbeständigen und korrosionsbeständigen Nylonrädern ausgestattet. Jeder Wagen zeichnet sich durch eine feste Struktur, einen flexiblen Betrieb, ein schönes Aussehen und eine einfache Reinigung aus. Jeder Wagen ist mit 48 Edelstahltabletts ausgestattet. Die einheitlichen Spezifikationen der Tabletts betragen 460 x 640 x 45 (mm). Sie werden durch einmaliges Stanzen geformt und haben ein schönes Aussehen, keine scharfen Winkel und eine hohe Festigkeit.

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.
