The tray dryer is suitable for drying various regular or irregular lumps of nuts. This machine can be used in conjunction with other equipment, or it can be used alone. The cashew nut dryer is also an ideal equipment for drying vegetables and nuts.
The main heating methods are electric heating and steam heating.
The main principle is to use steam or electricity as heat energy, use a fan to transfer heat to the material, and constantly replenish fresh air to discharge moist air.
Its biggest feature is that most of the hot air circulates in the box, which improves thermal efficiency and saves energy.

What problems should be paid attention to in the application of a tray dryer:

Humidity

The material has different humidity.

Drying temperature

According to different materials, to ensure the drying quality, choose a higher drying temperature to speed up the drying speed.
According to the nature of the material, match the drying capacity, the actual situation of the customer, and the host heat pump. The cycle of the drying chamber is different. The drying speed of different materials, the circulation mode, and the effect of the wind are different. These will also affect the configuration of the host.

Wind speed of hot air medium

The wind speed of the hot air medium in the drying room is related to the drying speed, material form, and material characteristics. A reasonable drying process often requires multiple tests. After each test, adjust the system according to the recorded data. Process requirements are different, and the same product may not deal in the same way under some distinct situations. Understand the drying capacity, material dehydration, drying cycle, and other factors. Select the appropriate type of host and conduct the drying test according to the traditional drying process.

Selection of drying speed and drying method

Control drying under certain process parameters, such as temperature, humidity, wind speed, etc., to ensure the retention of pharmaceutical ingredients during the drying process.

Material placement in cashew nut dryer

The stacking thickness and stacking method affect the drying rate. Control the stacking thickness reasonably to increase the heat exchange area and ventilation, and accelerate the drying rate.

Two methods of  drying materials with tray dryer

constant temperature and humidity law and drying curve. Some drying requirements are low, and low-value materials mostly use constant temperature and humidity. Most materials need reasonable control curves at different stages of drying to ensure the quality of the finished product.
