Drone pupae are unfertilized eggs laid by the queen bee in the drone house. After hatching into larvae, they enter the pupal stage (11-12 days old) after 7 days. At this time, the body of the bee pupa is the drone pupae. According to analysis and testing, the 21-day-old has the richest nutritional value. Freeze-drying […]

In the freeze-drying and storage processes of food, drugs, and organisms, many factors (such as chemical composition, freezing rate, freezing and dehydration stress, glass transition temperature, residual moisture in dried solids, temperature and humidity of the storage environment, etc.) can affect the stability of the active components and even lead to deactivation. Numerous experimental studies

When freeze dryer operating costs account for a relatively large proportion of total output value, reducing operating costs and improving production efficiency are particularly important. Factors affecting freeze dryer operating costs primarily come from three aspects: 1. Material influences, such as eutectic point, thermal sensitivity, geometric size, and thickness, all significantly impact the required drying
