Product Features

Tunnel Conveyor Type Microwave Herb Drying Oven

Instructions of tunnel herbs drying oven:

Drying is due to food and water vapor partial pressure inside and outside different process in the internal moisture to the surrounding air. Microwave dielectric heating and traditional heating drying equipment. When moisture content is above 50%, as the moisture content decreased, dielectric constant and dielectric loss factor will be reduced, especially at high temperature.

Moisture content is below 30%, the microwave penetration depth will increase significantly. Due to uneven temperature distribution and difficult to control the product in the terminal temperature of low moisture content components, microwave heating equipment will produce adverse effect on product quality.

The reason that choose tunnel herbs drying oven:

In the hot air drying, effective operating temperature range in the 60-90 °C, dry fruits and vegetables need 15 h time. In the process of the constant speed drying, the drying rate is determined by the enerLD transfer to the speed of food wet surface. Due to the evaporative cooling, the temperature of the product to lower than the later in the drying process. Once the surface is dry, from the inside to the surface of the mass transfer rate to keep the surface of the water permeability.

In the falling rate drying stage, diffusion rate determines the drying rate, and decrease with the content of water molecules. Due to the material surface evaporation cooling effect is reduced, resulting in surface temperature. Under the hot air drying temperature, volatile flavour compounds of group branch loss, structural changes, such as: hardening inhibits after drying, and drying time was prolonged, thereby resulting in the destruction of vitamins, color and flavor of the chemical and enzymatic reaction.

Microwave drying, microwave for material inside and outside the heating process at the same time. Materials due to the internal and external temperature at the same time, and the material surface is direct contact with air, so the internal temperature of the material will be sligLDly higher than the surface temperature. At the same time the moisture inside the material by the external to internal migration, the material surface, evaporation and air.
Thus, microwave drying, the drying speed is higher than other drying methods
