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

Estimation of hourly power consumption of a 100 square meter food freeze dryer under different heating methods (electric heating vs. electric steam heating) The electric heating is 50-90kw/hour. It depends on the different kinds of product and productioon process. If you use a higher drying, say 80-90 degrees, it will consume much electricity. If you
Freeze-drying technology (FD technology) is known as the “gold standard for food preservation”, and freeze-dried cheese is a perfect combination of technology and nutrition: Strict selection of raw materials Only high-quality fermented cheese (such as cheddar, mozzarella) is selected, with a protein content of ≥20% and rich calcium to ensure a mellow basic flavor. Ultra-low

Freeze-dried coffee is instant coffee that converts coffee extract into solid particles through freeze-drying technology, which can better preserve the flavor and aroma of coffee. The process flow is as follows: Coffee extraction: After the roasted coffee beans are ground, they are extracted with hot water under high pressure to obtain a high-concentration coffee liquid.

Freeze-dried bird’s nests are pre-frozen in the bird’s nest at minus 40°C using a food freeze dryer, and then the solid water is sublimated under a vacuum environment to achieve an absolute moisture content of less than 5%, leaving the original structure of the bird’s nest intact. It effectively avoids the thermal loss of sialic

The food freeze dryer freezes the water in the material into a solid by cooling it down, and then sublimates the solid water ice into water vapor directly by reducing the vacuum and gently heating it to achieve the purpose of dehydration. Compared with the dehydration method of heating and drying, freeze drying has many
