An electric thermal drum dryer is a device that generates heat through heating elements and circulates the air in the box evenly with the help of a circulating fan to achieve rapid and uniform drying. It is widely used in scientific research, industry, medical and other fields for drying, baking, sterilization and temperature testing.

VI. Operational Highlights and Precautions
6.1 Pre-use preparation
Check whether the power line is intact and the grounding is reliable
Make sure the box is clean inside and outside and free of impurities around the heating element
Check whether the seals are intact and the door can be fully closed
Place the equipment on a well-ventilated flat surface, away from flammable and explosive materials
6.2 Standard operating procedures
Turn on the power and turn on the power switch
Set the operating temperature (initial temperature should not be too high)
Turn on the drum switch to promote air circulation
Place the material (spread evenly so as not to accumulate too thick)
Monitor the state through an observation window during operation
When drying is complete, turn off the heating and wait for the temperature to drop below 60 ° C before taking the ingredients
6.3 ⚠️Important security warnings
form
Prohibited matters Dxplaination
Flammable and explosive items should not be placed in a drying box for heating to avoid explosion
volatile chemicals are strictly forbidden to be put in
Excessive use. It is strictly forbidden to set more than the device's rated maximum temperature
Unstaffed. Regular patrols should be conducted during operation
Open the door at high temperatures Try to avoid opening the door in a high temperature.
VII. Selection recommendations
Choose the temperature range according to material characteristics: thermally sensitive materials choose low-temperature type (< 100 ° C), ordinary materials choose 200 ° C.
Choose volume based on load: Consider the shape size and number of load carriers
Choose the controller according to precision requirements: a display type for general experiments, an intelligent program type for precision experiments
Choose the material according to the use environment: Corrosion environments recommend stainless steel casings
Spare heat space: not less than 30 cm from the wall on the surrounding and back of the box
VIII. Maintenance and maintenance
Clean the interior after each use until the box is completely cooled
Regularly check the heating components and the operation of the turbines
Seal strips that are old or damaged should be replaced in a timely manner.
When long-term use is discontinued, the power should be disconnected, the box should be dried, and the electricity should be turned on regularly to dehumidify.
