The following is usedDrying method and equipment for Cornus officinalisThe steps are as follows:
1、 Preliminary preparation
Selecting and Cleaning Cornus officinalis
Select fresh, pest free, moldy and spoiled Cornus officinalis fruits. Remove impurities, fruit stems, and other foreign objects.
Gently rinse the Cornus officinalis with clean water to remove dust and dirt from the surface, then drain the water.
preheating oven
Start the oven in advance, set the initial temperature to 40 ℃ -50 ℃, preheat it, and let the internal temperature of the oven reach a relatively stable state to prepare for the subsequent drying process.
2、 Set oven parameters
Temperature setting
Phase 1: Set the temperature between 50 ℃ -60 ℃ and maintain this temperature for about 2-3 hours. This stage is mainly to gradually adapt the Cornus officinalis to the drying environment, initially remove some moisture, and avoid excessive temperature that may cause the surface of the fruit to dry too quickly and affect the release of internal moisture.
Phase 2: Raise the temperature to 60 ℃ -70 ℃ and continue drying for 3-4 hours. At this stage, the internal moisture of Cornus officinalis continues to dissipate, accelerating the drying process.
Phase 3: Finally, adjust the temperature to around 50 ℃ and continue drying for 1-2 hours to consolidate and enhance the aroma of Cornus officinalis, making the drying degree more uniform while retaining its certain flavor and nutritional components.
Ventilation settings
Ensure that the ventilation system of the oven is functioning properly and maintain good air circulation. This can promptly remove the moisture emitted by Cornus officinalis, improve drying efficiency, and prevent moisture from accumulating in the oven, which can affect the drying effect.
3、 Drying process operation
Plate installation and placement
Timed flipping
During the drying process, flip the Cornus officinalis every 1-2 hours. Clean tools such as wooden shovels or bamboo chopsticks can be used to gently flip and ensure that the upper and lower layers of Cornus officinalis are evenly dried, avoiding local overheating or incomplete drying.
Observation and adjustment
Observe the color, morphological changes, and dryness of Cornus officinalis at any time. You can judge by pinching the fruit. When the fruit becomes harder and the moisture content meets the requirements (usually dried to a moisture content of about 10% -15%), you can stop drying. If uneven drying or unsatisfactory progress is found, adjust parameters such as temperature, time, or flipping frequency in a timely manner.
4、 Post processing
cooling
After drying, remove the Cornus officinalis from the oven and place it in a well ventilated, dry, and sun free place to cool naturally. Avoid stacking together to ensure sufficient air circulation and allow the Cornus officinalis to cool evenly to room temperature.
packaging storage
After the Cornus officinalis cools down, package it according to actual needs. You can choose containers such as food packaging bags, plastic cans, or glass bottles with good sealing properties for storage. During the packaging process, it is important to ensure that the container is dry and clean, and to eliminate air as much as possible to prevent the Cornus officinalis from getting damp, oxidized, or contaminated with odors. Store the packaged Cornus officinalis in a cool, dry, and well ventilated place, avoiding direct sunlight and high temperatures to extend its shelf life.Drying method and equipment for Cornus officinalis
