Chinese wolfberry is a valuable medicinal herbs and tonic, native to the north of China, due to the cultivation of the fruit into medicine, many provinces and regions in the center and south of China has also been introduced into cultivation, especially in Qinghai, Ningxia and Tianjin area cultivation, high yield.
We come into contact with goji berries are dry goji berries, why not fresh goji berries?
Fresh goji berries have high water content, high sugar content and delicate flesh, which is easy to break, which brings challenges to transportation and preservation. Therefore, after picking down the wolfberry, we need to find a way to dehydrate and dry it to ensure the quality of wolfberry, because the nutrients and effective substances will be lost in large quantities after breaking.
Wolfberry fruit ripens one after another from June to November, and should be picked at the right time. When the fruit from green to red or orange-red, fruit tip, flesh slightly fluffy can be picked. Wolfberry fruit should be carried out after 10 o'clock in the morning on a sunny day, do not pick after rain or dew. In case of prolonged cloudy and rainy weather, the fruits should be immediately thinly spread on the sun mat, and then processed after drying the water naturally.
Wolfberry fresh fruit shelf life is very short, generally only 2 to 3 days or so, deep processing is an important part of the dehydration preservation. Nowadays, wolfberry planting scale are relatively large, so once the harvest season, you need to quickly dry, if not quickly dry, then the wolfberry will be broken, bringing huge economic losses. Therefore, relying on natural drying methods to dry is not feasible.
Wolfberry drying, the upper limit is 55 ° C, generally controlled at 50 ° C is good, the temperature control is not good but will lead to the quality of wolfberry decline. Ensure the quality of wolfberry after drying, the drying process needs to do a good job of dehumidification, because the moisture content of wolfberry is up to 80% or more, the drying room in the heating three or four small children, the indoor air humidity will be very high, the water vapor is not discharged in time will affect the drying efficiency and quality of wolfberry. However, if the ventilation and drainage of moisture, it will dissipate a lot of heat.
Improve the quality of wolfberry drying, now most of the use of drying dehumidifier to complete.
PARKOO drying dehumidifier, with reference to the principle of nikano, at the same time with closed dehumidification and warming two functions. Internal cycle closed drying, without strong exhaust, the use of high temperature to volatilize the water inside the wolfberry, through the internal cycle of dehumidification system constantly discharged water, directly and quickly reduce the humidity of the drying room, to achieve the purpose of drying wolfberry. As there is no need for strong exhaust dehumidification, the drying process reduces the loss of heat energy; the heat generated in the dehumidification process can also be involved in the drying, which can speed up the drying speed and reduce the drying costs.
The drying process of wolfberry, the temperature is not static. Warming stage temperature and humidity controller temperature control is set to 40 ° C; moisture removal stage temperature control 45 ° C; depth of drying temperature of 50 ° C ~ 55 ° C, humidity control at 55%, after a period of cooling and then rewarming, and finally uniform moisture removal. PARKOO drying dehumidifier can set drying mode and temperature and humidity parameters through intelligent temperature and humidity control system, drying in stages to better improve the drying quality of wolfberry.
With the improvement of people's quality of life, environmental protection and food safety awareness is getting stronger and stronger, PARKOO drying dehumidifier as a safe, environmentally friendly drying and dehumidification equipment to replace the original old drying and dehumidification equipment, change the traditional drying method, convenient and trouble-free, dehumidification and temperature control precision, energy saving and high efficiency, to better meet the demand for drying, and improve the quality of Chinese wolfberry.
