Industrial drying ovens can be divided into six core categories based on their working principles, temperature ranges, and industry adaptability. Each category of equipment has significant differences in energy efficiency ratio, processing capacity, and process adaptability.

1、 Classified by heating method

|Type | Temperature Range | Core Advantages | Typical Applications|

|electrothermal|50-600 ℃ | Temperature control accuracy ± 0.5 ℃ | Electronic component curing, laboratory|

|Gas powered|200-800 ℃ | 40% reduction in operating costs | Ceramic sintering, metal heat treatment|

|Microwave assisted|40-250 ℃ | Drying time reduced by 60% | Dehydration of medicinal herbs and food|

|Fuel/Coal|300-1000 ℃ | Ultra large capacity (single ton level) | Building material drying, ore processing|

2、 Classified by structural form

1. Box type oven

• Studio volume: 0.1-50m ³

• Features: Batch processing, suitable for small batches of high-value materials (such as precision mold drying)

2. Tunnel oven

• Conveyor belt speed: adjustable from 0.5-10mm/min

• Features: Continuous production, compatible with assembly lines (such as lithium battery electrode drying)

3. Tower type oven

• Multi layer structure (usually 6-20 layers)

• Features: Vertical space utilization, saving floor space (such as chemical particle drying)

3、 Classified by special process

|Type | Key Technical Parameters | Industry Cases|

|vacuum drying oven|Vacuum degree 0.1-10Pa | Pharmaceutical and nanomaterials|

|Inert gas oven|O ₂ content ≤ 5ppm | Lithium battery positive electrode material, rare earth treatment|

|Explosion proof oven|Solvent based coatings, petrochemical industry|

|Clean oven|Dust particles ≤ Class 100 | Semiconductors, medical devices|

4、 Classified by temperature level

• Low temperature type(50-150 ℃): Food drying, curing of polymer materials

• Medium temperature type(150-400 ℃): Powder metallurgy, motor insulation paint treatment

• high-temperature type(400-800 ℃): Ceramic glaze firing, alloy heat treatment

• Ultra high temperature type(800-1200 ℃): requires silicon carbide heating element, used for special ceramics

5、 Classified by control system

1. Basic TypeMechanical instrument temperature control (± 5 ℃ accuracy)

2. intelligent type：

• PLC control+touch screen (capable of storing multiple process curves)

• IoT remote monitoring (such as reducing the failure rate of Wuhan GeTe brand ovens by 70%)

6、 Classified by energy efficiency

|Grade | Thermal Efficiency | Representative Technology|

|Level 1 | ≥ 75% | Waste heat recovery+variable frequency fan|

|Secondary | 60-74% | Double layer insulation+hot air circulation|

|Level 3 | ≤ 59% | Traditional resistance wire heating|
