Uses:
Widely used in the fields of biochemistry, agricultural research, environmental protection, chemical pharmaceuticals, medical and health, food, and machinery for research and application. It serves as a tool for drying glassware, conducting heat denaturation and hardening experiments on samples, removing residual moisture from specimens, dry heat sterilization of glassware used for microorganisms, preheating before heating experiments, experiments on hardening or softening of food and chemical substances during heating, moisture removal, extending the shelf life of food under harsh conditions, and drying and heat resistance testing of building materials and electronic components. It is also used for drying, baking, disinfecting, sterilizing, and material transformation experiments. Additionally, it is commonly used in industrial and mining enterprises for the drying and baking of various materials.
Vertical Air-Cooled Drying Oven Performance Features:
– Mirror-like 304 stainless steel interior, rounded corners, with adjustable air inlets and outlets;
– Maximum temperature of 300℃, with an accuracy of 1℃, and equipped with PID self-tuning function.
Chamber Structure and Materials:
– Outer Chamber Material: The outer box is made of high-quality cold rolled steel treated with phosphoric acid film salt and then high-temperature spray plastic, with blue door and white body color.
– Studio Material: Equipped with a mirror-like stainless steel interior, removable stainless steel electropolished shelves, tempered glass viewing window.
– Internal Structure: Reasonable air duct structure and gentle airflow circulation design, with fan-forced heat dissipation circulation, ensuring good temperature uniformity in the working chamber, and a unique geometric cavity clean design.
– Insulation Material: High-density glass fiber cotton is filled in the insulation layers on the front, back, left, right, top, and bottom of the box.
– Sealing Method: The chamber door and the working chamber are sealed with high-temperature resistant silicon rubber seals to ensure the sealing of the working chamber. The inner panel of the chamber door is made of stainless steel. A double-layer tempered glass observation window is located on the door for observing changes in the samples inside the chamber. Transparent and insulating, the chamber back has an air intake hole and a safety ventilation hole.
– Temperature Port: The PT100 sensor enters from the back of the chamber.
– Terminal Post: The wiring terminal for the heating elements is located at the bottom rear of the chamber.
– Controller: Located at the top of the chamber, with an integrated control system.
– Heating Element: Stainless steel heater.
Temperature Control System and Features:
– Custom-designed, digital display, microcomputer intelligent temperature controller with PID self-tuning function for high temperature control precision.
– PT100 high-responsive thermal sensor and environmental scanning microprocessor chip form a high-precision, high-intelligence temperature control characteristic.
– Built-in temperature calibrator to adjust minor temperature errors. Automatic alarm when working temperature deviates from the set temperature, with automatic power-off protection for heater malfunction.
– Timer setting function, allowing any working time from 1 minute to 9999 minutes to be set, and the setting display window is closed at the end of the timing. (Temperature reaches the start time, time is up, automatic shutdown)
– Both set parameters and actual parameters can clearly display set temperature, measured temperature, and timer time. Each parameter display is visible, with a modular design of the upper limit temperature tracking function. When the measured temperature deviates from the allowed range, the instrument will sound (light) alarm and automatically cut off heating.
Air Circulation System:
– The circulation blower is located in the middle of the stainless steel heater on the back of the box,
– Equipped with a long-shaft fan motor and multi-vane aluminum alloy blades to achieve horizontal convection and diffusion of air circulation within the box in an arc shape, ensuring uniform temperature throughout the box and maintaining stability.
Heating System:
– Stainless steel heaters are located at the back of the box, controlled by the PT100 sensor,
– The heating output power of the heaters is uniformly controlled by a microcomputer within the intelligent instrument.
Safety Protection System:
– Fusible protection device
– Chamber overheat protector, sensor fault alarm, upper limit overheat alarm
– Fan overcurrent protection
