Come ben noto alimento salutare tradizionale, le date rosse contengono molti nutrienti. La maggior parte di essi \u00e8 essiccata e consumata direttamente dai consumatori come frutta secca priva di impurit\u00e0. Inoltre, le zone di coltivazione delle date rosse sono relativamente centralizzate, e la maggior parte delle date rosse fresche viene raccolta in autunno quasi contemporaneamente e serve l'intero mercato.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Come seccare il jujube?<\/h2>\n\n\n\n

Il nucleo del trattamento delle date rosse \u00e8 l'essiccazione. Il processo di essiccazione \u00e8 composto dall'evaporazione dell'acqua e dalla conversione degli zuccheri presupponendo di mantenere la qualit\u00e0 originale della giugnia per quanto possibile. Per lo stoccaggio, il trasporto e la vendita, le date rosse fresche devono essere pulite, essiccate, raffreddate, ammorbidite, sterilizzate, confezionate.<\/p>\n\n\n\n

Red dates abound in sugars. Among them, the polysaccharide is not sweet and only becomes sweet after inverted into simple sugars by the function of the biological enzymes. It is the reason why cured jujube is sweet. If we want to invert sugars fully, we need to strengthen the activity of the biological enzymes. After a long time of practice in our forno di essiccazione<\/a><\/strong>, we have found the most suitable temperature for completely sugar conversion is about 60\u00b0C.<\/p>\n\n\n\n

Processo di essiccazione delle date rosse<\/h2>\n\n\n\n

Nel processo di essiccazione delle date rosse, ci sono molte dettagli che devono essere chiariti. In linea di massima, il processo di essiccazione \u00e8 diviso in quattro fasi: preriscaldamento, evaporazione, asciugatura, raffreddamento. Di seguito alcune precauzioni e introduzione al processo durante l'essiccazione.<\/p>\n\n\n\n

Preheating:<\/strong> If we directly put red dates in the environment where the temperature is suitable for sugar conversion, the extreme temperature difference will make red dates set off the protective reaction. The cell orifice in the skin will shrink and the crust will become hard to prevent water from evaporating. Therefore, sufficient preheating is required in the early drying to prepare for the evaporation. First, the red dates need to be dried at 35\u00b0C for 6-10 hours. When the temperature of red dates reaches 45\u00b0C, your finger will feel hot when touching it. After drying them for 7-8 hours, use your finger to press the red date and wrinkles will appear on the surface. When the temperature is at 45\u00b0C-48\u00b0C, there will be some small water drops on their skin. <\/p>\n\n\n\n

Evaporation:<\/strong> Raise the temperature to 65\u00b0C (Note: the temperature shall not be higher than 70\u00b0C) within 8-12 hours to evaporate most of the free water. Keep the indoor temperature stable for constant evaporation. The drying process goes well when the wrinkles appear on the surface.<\/p>\n\n\n\n

Drying up:<\/strong> When the temperature in the red date is uniform, this step will end within 6 hours. In this phase, the moisture content of red dates is not high, and thus more attention shall be paid to temperature control. It is best to keep the temperature at 50\u00b0C. At this moment, relative humanity has been declined. As the water in the red dates is gradually balanced, the drying process is completed. Note that the dried red dates shall be taken out in time.<\/p>\n\n\n\n

Cooling:<\/strong> Keep good ventilation and heat dissipation for dried red dates. Pile them up until being cooled. If the dried red dates are just taken out from the cabinet, and directly piled up in the warehouse, their sugars will ferment and go bad, and the pectose will be broken down into pectin and pectic acid due to high heat. Therefore, it is necessary to wait for the completely cold zone before piling up.<\/p>\n\n\n\n
