Domestically, low-temperature drying ovens feature a pioneering streamlined curved design. The outer casing is constructed from cold-rolled steel plates with an electrostatic powder coating finish. The temperature control system employs microcomputer single-chip technology for precise temperature regulation, timing functions, and over-temperature alarms. A rational air duct and circulation system ensures minimal temperature variation within the working chamber. The display utilizes dual high-brightness digital tubes for accurate, intuitive readings and superior performance. Touch-sensitive buttons facilitate parameter setting and adjustment. The temperature sensor employs a capacitive, genuine imported component.
Now, let me explain the unique operation of the steam oven: After connecting the power supply, you may turn it on. First activate the heating switch, then start the blower switch to initiate fan operation. Next, set the desired temperature using the control panel buttons. When the temperature reaches the set point, the indicator light will turn off. During initial stabilization, the temperature may continue to rise slightly due to residual heat; this phenomenon will stabilize within approximately half an hour. Throughout the constant-temperature phase, the internal thermostat automatically regulates the temperature without manual intervention. This hands-off operation mirrors the convenience of Apple software—highly user-friendly and intelligent!
The mixing chamber of the low-temperature drying oven also features a draft hood, whose diameter is selected based on airflow requirements. Vertical air channels are installed within the drying tower walls to direct cool air directly into each drying bed layer, regulating temperature and humidity. Most moisture in germinated rice evaporates during the first four layers, with the final electric heating drying occurring in the bottom two layers.
High-capacity rice sprout drying towers are equipped with two centrifugal fans. Drying chamber height directly impacts drying efficiency—greater height yields superior results. Typically, middle and lower drying chambers measure 2–3 meters tall, while the upper chamber requires at least 6 meters to facilitate rapid vapor escape.
