Fruit Dryer Machine

Common materials include dried fruits and vegetables (such as dried mango and dried mushrooms), meat products (such as cured meat and sausages), nuts, grains, and dried seasonings. The technology is also applied in other industries involving raw materials, seafood, medicinal herbs, traditional Chinese medicinal ingredients, freshwater fish, protein extracts, sauced duck, vegetables, soy products, and more.

 Fruit and vegetable dryer machine equipped with high temperature and low noise axial flow fan, using central PLC control system, the entire circulation system of the vegetable dryer machine is fully enclosed, two-way air box circulation baking, bilateral symmetrical air distribution system, only moisture removal system, high-temperature resistant observation window, Temperature self-control, easy installation and maintenance, Excellent performance, is general-purpose drying equipment, meat dryer machine.

 1. The RH series box adopts a frame structure formed by welding SUS304 stainless steel plate and stainless steel profile. The oven shell is made of a stainless steel insulation plate, riveted and welded, and the surface is flat, with a flatness of 3/1000mm. The oven is made of a 1.2mm stainless steel plate, which is ground and polished after argon arc welding.

2. The insulation layer of the industrial food dryer machine in the box is filled with high-quality aluminum silicate fiber cotton. This spice dryer machine has the characteristics of high heat resistance, low thermal conductivity, good chemical stability, and strong thermal shock resistance. The thickness is 75mm, and the surface temperature does not exceed the ambient temperature of 10 °C.

3. The convection wall of the electric food dryer machine in the box is adjustable, and the temperature in the box is uniform by adjusting the ventilation gap of the convection wall. The no-load temperature in the box is ±2℃.

4. The hot air circulation of the box adopts a high-temperature and low-noise axial flow fan; the fan power is 0.75KW/unit, and it is installed on both sides of the box.

5. The top of the box is equipped with 1 moisture outlet with a size of 150-150mm, and a supplementary air inlet with a size of 150-150mm.

6. The air dryer machine is equipped with 90 baking trays, each with a size of.

At the core of this equipment-to put it simply-is a fan that effectively forces the creation of a "closed-loop hot air circuit." This isn't the open-system variety where hot air escapes or leaks away; rather, it involves a forced circulation system where the air dutifully returns via dedicated ductwork. Within this closed loop, hot air repeatedly passes through the layer of material, relying on convective heat transfer: heat flows from the air into the material, simultaneously extracting and carrying away the moisture trapped inside. With continuous heating on one side and simultaneous moisture extraction on the other, both processes occur in tandem. Consequently, the three distinct operations-drying, curing, and constant-temperature treatment-can all be accomplished within a single, unified workflow.

Now, for some practical insights that you won't find in the instruction manual: you must adjust the fan speed and damper opening while keeping a close eye on the humidity level of the return air. If the opening is too wide, the hot air escapes before it has had a chance to sufficiently heat the material, causing energy consumption to skyrocket. Conversely, if it is too narrow, moisture cannot be effectively expelled; this causes the material's surface to become saturated and "pasty," while the interior remains damp. There is also a distinct advantage to this closed-loop design: during winter or on humid mornings, you needn't worry about incoming cold air causing a drastic drop in temperature. However, a word of caution: after prolonged circulation, dust and debris will inevitably accumulate in the filters and air ducts. As resistance builds up, the airflow volume can drop significantly-often so gradually that you might not even notice it happening. Experienced operators typically use the back of their hand to check the temperature and scent of the air at the return vent every four hours; if the air smells sour or acidic, it indicates that moisture extraction is being impeded, and immediate adjustments are required.

Finally, that phrase "effective drying" may sound simple enough, but in reality, it is achieved precisely through this closed-loop circulation system-by maintaining a stable temperature while sustaining a robust airflow-thereby ensuring that the material remains free from scorching or moisture reabsorption from start to finish.
