Scope of Application:
The Vertical Precision Blast Drying Oven is a versatile equipment that achieves precise temperature control through a forced convection air duct and PLC control. It is specifically designed for the drying, baking, sterilization, and heat treatment of non-flammable and non-explosive materials. Its core applications include industrial manufacturing (electronic component aging/chemical raw material dehydration), medical and pharmaceutical (instrument dry heat sterilization), food processing (meat/vegetable drying), and scientific research and quality inspection (material temperature resistance testing). It also supports routine operations in teaching laboratories (such as glassware drying).
Structural Features:
Outer Casing: The casing is made from selected cold-rolled steel plate base material, treated with an electrostatic baking paint process. This forms a dense protective layer on the surface, which is hard, robust, and offers excellent rust resistance.
Working Chamber: Interior made of stainless steel, mirror-polished. Shelf brackets feature a quick-release design for easy adjustment, installation, and removal.
Insulation Layer: A thermal insulation system is employed between the outer casing and the working chamber, providing excellent heat retention. This effectively ensures stable and accurate internal temperature and minimizes impact on the ambient environment.
Sealing Technology: Utilizes high-density synthetic heat-resistant silicone sealing strips to prevent heat loss and ensure long-term operation at high temperatures with a long service life.
Viewing Glass: Double-layer tempered glass viewing window allows clear observation of items inside the chamber while providing good thermal insulation.
Air Flow: Forced convection ventilation structure improves temperature response speed, enhances temperature uniformity, and reduces temperature fluctuation.
ontrol Panel: PLC intelligent touch screen display temperature controller, offering high precision, no overshoot, multi-data display on a single screen, temperature calibration function, timer function, and 30-segment program control.
Equipped with a USB interface for real-time data storage.
Supports three-level permission management and audit trail.
Temperature Control: Configured with a constant temperature system and equipped with highly sensitive sensors to ensure stability during continuous operation.
Fan: Equipped with a fan speed control device, allowing for arbitrary adjustment of the air volume.
Safety System: Includes auxiliary temperature control and leakage protection.
