The selection of hot air drying for lemon slice dryer has the following advantages, suitable for efficient, economical and stable quality production needs:
Efficient and rapid drying
Hot air quickly removes moisture through circulation, shortening drying time. Compared to natural air drying or low-temperature drying, hot air drying can significantly improve production efficiency, especially suitable for lemon slices with high moisture content.
Uniform heating, stable quality
The design of the hot air circulation system (such as reasonably arranged air ducts or fans) ensures uniform temperature distribution in the drying room, avoids local over drying or non drying phenomena, ensures consistent color and even dryness of lemon slices, and reduces the rate of defective products.
Flexible control parameters
It can accurately adjust temperature (usually 40~70 ℃), wind speed, and humidity to adapt to different batches or thicknesses of lemon slices. For example, rapid dehydration at high temperatures in the early stages, followed by lowering the temperature in the later stages to retain nutrients and balance efficiency and quality.
Low cost and easy to maintain
The equipment structure is simple (heater, fan, box, etc.), and the purchase and operation costs are lower than those of freeze-drying and other technologies, making it suitable for small and medium-sized processing enterprises. Daily cleaning and component replacement (such as filters) are also relatively convenient.
Large scale production capacity
The multi-layer tray or continuous conveyor design can handle large quantities of lemon slices, meeting the needs of industrial production, while reducing unit energy consumption with increasing output and improving economic efficiency.
Preserve appearance and flavor
Appropriate hot air temperature (such as 55-65 ℃) can effectively dehydrate and reduce the loss of thermosensitive components such as vitamin C, avoiding browning or coking, and maintaining the golden color and natural fragrance of lemon slices.
