When choosing a pepper dryer, both the mesh belt dryer and the heat pump dryer have their own advantages and disadvantages. The specific choice should be determined according to actual needs and the use environment. The following is a detailed comparison of the two dryers:

1. Drying principle

Mesh belt dryer: A drying equipment that uses a steel mesh as a conveyor belt to carry materials for continuous drying. The air is heated mainly by high-temperature wind or electric heaters to gradually reduce the humidity and complete the drying process.

Heat pump dryer: Using heat pump technology, it absorbs heat from the air and releases heat after compression to achieve internal heat transfer until the material is dried. There is almost no heat loss in the whole process, and the thermal efficiency is higher.

2. Energy consumption

Mesh belt dryer: Since electric heating or high-temperature wind is required for drying, the energy consumption is relatively high.

Heat pump dryer: Using heat pump technology, the heat is fully utilized, so it is more energy-saving than the mesh belt dryer in terms of energy consumption.

3. Cost

Mesh belt dryer: The equipment cost may be relatively low, but the operating cost (such as electricity consumption) may be high.

Heat pump dryer: The equipment cost may be high, but due to its high efficiency and energy saving characteristics, the long-term operating cost may be low.

Conclusion

If the drying efficiency is not high and the main materials to be processed are granular foods, etc., the mesh belt dryer may be an economical and practical choice. If there are high requirements for drying efficiency, environmental protection and energy consumption, and the budget allows, the heat pump dryer is a better choice.
