Electric hot air drying oven is a drying equipment widely used in industries such as pharmaceuticals, chemicals, light industry, and food. It has the advantages of fast drying speed, good drying effect, and wide applicability. When using an electric blast drying oven, it is necessary to pay attention to some safety precautions. This article will introduce the safety operating procedures of the electric blast drying oven.
1、 Preparation before use
Before using an electric blast drying oven, the following preparations need to be made:
1. Check the equipment
Before using the electric blast drying oven, it is necessary to inspect the equipment to confirm that there are no faults or damages. Especially, it is necessary to confirm whether key components such as heaters, temperature measuring electrodes, and temperature regulators are working properly, and whether distribution lines, sockets, etc. are safe and reliable.
2. Clean up thoroughly
Before use, it is necessary to clean the electric blast drying oven. Remove any dust, garbage, and other debris that may exist inside and outside the device to avoid any adverse effects on it.
3. Preheating
It is necessary to preheat the electric blast drying oven to achieve the desired temperature. During preheating, it is necessary to perform reasonable and safe operations based on the required temperature of the equipment, and ensure that the fan of the heat exchanger has been started.
2、 Operating procedures
When using an electric blast drying oven, the following operating procedures should be followed:
1. Equipment operation
Proper operation is required according to the device instructions. When turning off power, plugs, switches, etc., precautions must be taken to prevent shaking and ensure safety, while also paying attention to moisture and dust prevention.
2. Feeding operation
It is necessary to operate according to the specific characteristics of the material to avoid accidents or losses caused by material properties not meeting equipment requirements. When adding materials, ensure smooth gas circulation inside the dryer to avoid suffocation or contamination of the dryer.
3. Temperature regulation
It needs to be adjusted appropriately according to specific processing requirements, material properties, and other characteristics. When adjusting the temperature, the temperature change should not be too fast, and there should be a moderate buffering process to avoid affecting the processing quality.
4. Security measures
It is necessary to maintain an appropriate temperature inside the drying oven to avoid excessive temperature and pressure. If pressure gauges are installed, pressure changes should be checked at any time. Better anticipate and control potential accidents to reduce losses.
5. Safety prevention
During the operation, it is important to pay attention to safety precautions. Check if temperature sensors, insulation resistance meters, and other equipment are functioning properly; Keep the operating area dry and ventilated to prevent potential hazards such as fires.
3、 Shutdown operation
Before shutting down, the following preparations should be made:
1. Cleaning equipment
After stopping the electric blast drying oven, the equipment should be cleaned in a timely manner. Especially to remove impurities, dust, etc. generated during the processing to avoid clogging the equipment and affecting its next use.
2. Turn off the device
Before shutting down, it is necessary to turn off the power and heater so that the equipment can reach a cooling state and avoid potential hazards.
3. Maintenance and upkeep
Maintenance work is required for the electric blast drying oven. Especially, it is necessary to inspect key components such as heaters, fans, and temperature sensors of the equipment to ensure its normal operation.
