Classified by air supply method and applicability:
oneHorizontal air supply: suitable for objects that need to be placed on a tray for baking; The hot air of horizontal air supply is blown out from both sides of the studio, so you can bathe in the objects in the tray! The baking effect will be very good. On the contrary, it is not suitable to use vertical air supply for baking objects placed in trays. Vertical air supply hot air is blown from top to bottom, which will block the hot air and prevent it from reaching the lower layers, resulting in poor baking effect!
twoVertical air supply: suitable for baking objects placed on a grid. The vertical air supply hot air is blown from top to bottom. As it is a grid, the vertical circulation will be very good, allowing the hot air to completely bathe on the object! Of course, objects placed on the grid can also be horizontally ventilated, depending on the characteristics of the object itself!
Moisture removal system
one)Dehumidification fan: The dehumidification air volume is determined by the oven manufacturer's calculation, and the air volume adjustment method is variable frequency adjustment
two)Moisture removal pipeline: quantityonegroup
After the hot air in each drying chamber completes heat and mass transfer, the temperature decreases, the air humidity increases, and the drying capacity decreases. It is necessary to timely discharge some of the exhaust gas. The exhaust gas is collected from each dehumidification outlet and sent to the dehumidification main pipe. Part of the humid and hot exhaust gas is discharged to the outside in a timely manner by the dehumidification system under the negative pressure of the fan; Another part of the humid and hot exhaust gas is mixed with fresh air through a circulating fan and reused.
Due to the varying evaporation rates of water in different temperature zones, the dehumidification capacity of each zone should be controllable and manually adjustable.
Dry temperature zone
The system is divided into multiple convective drying units, and multiple temperature zones are independently controlled. Multiple drying units are allocated as follows: heating stageoneUnit, constant speed dryingtwoUnit, slow down dryingoneUnit, verify drynessoneA unit. This verification area is designed to regulate the final state of materials while meeting the drying requirements of the product.
Uniform air device: Uniform air plate
According to the paving width of the materialzero point threeAbout meters, a diameter of5mmThe circular hole is placed according to the specific air duct to ensure uniform heating and drying efficiency of the material. The uniform air plate adopts a quick installation structure, which can be easily disassembled and cleaned.
