We offer a wide range of high quality of equipment & machines for food drying.
The wolfberry drying machine uses a hot air stove to supply hot air, compared with the traditional drying, it increases the drying rate by 20%--30%. The finished product, color, dryness, quality and energy consumption of the wolfberry are satisfactory, not only hygienic and safe, but also the dry yield of wolfberry has been greatly increased, the quality of wolfberry has been improved, and significant economic benefits have been achieved.
First, lay the wolfberry flat on the special plate, divide it into 11-12 layers, and the interval between each layer is about 14-15 cm. Place it in the drying room of the wolfberry dryer and dry it in two stages.
Then adjust the temperature of the wolfberry dryer to between 42-48°C, dry for 24-36 hours, and wait until some fruits appear partial shrinkage wrinkles;
Finally, the temperature is raised to between 50-55°C, and the drying process is completed for about 24 hours. The drying process will remove about 75% of the water content of the wolfberry, and the actual quality of the material is about 25%.
The common phenomenon of goji berries drying is that the water diffusion on the surface of the fruit is greater than the internal diffusion rate, and the extravasation rate of the free water in the fruit is greater than the extravasation rate of the structural water.
If the temperature in the drying room is too high, the surface water of the fresh fruit will be lost too quickly, and the extravasation of the water in the fruit will not be able to supply it, the epidermis will blister, blocking the drainage pores, but the water in the fruit will not be able to drain out. Decolorization and quality degradation.
The fresh fruit is first subjected to surface oil cold dipping treatment, plus appropriate temperature and wind speed, while the skin is dehydrated, the temperature that penetrates into the fruit through the stomata increases, which is conducive to the discharge of water in the fruit, thereby accelerating the drying speed and ensuring drying quality.
N0.1 temperature control
The drying temperature and humidity are controllable, and the color, nutrition, flavor and texture of the wolfberry remain unchanged, and the quality of the material after drying is good.
NO.2 Intelligent touch screen
Using touch screen programmable control, after setting the corresponding program, there is no need for special personnel to supervise the whole process, saving time and labor.
NO.3 closed drying room
The whole drying process is completely closed, and the wolfberry is not in contact with the outside world, which ensures that the heat and air volume in the drying room is not lost, and achieves the effect of energy saving.
NO.4 Dry evenly
The drying room has built-in multiple circulating fans to ensure that the air volume and temperature in the drying room are uniform, the drying effect of the same batch of wolfberry is consistent, and there is no dead angle for drying.
N0.5 small footprint
The drying equipment can be installed outdoors or indoors with only the unit and drying room, which saves a lot of space compared to the traditional natural drying.
