Expanded donkey-hide gelatin dried by microwave vacuum at low temperature

Under the action of microwave vacuum low-temperature expansion dryer, donkey-hide gelatin paste can generate heat quickly and evaporate water to achieve the purpose of drying. At the same time, micro-bubble pores are generated to achieve the purpose of expansion. This drying method does not need to be conducted through media,
The microwave energy directly acts on the extract. The drying process will not have the problems of surface hardening and difficult drainage. The drying temperature of the extract is low and can maintain the efficacy. Therefore, it has the advantages of high drying quality, fast drying speed, low production cost and energy saving
The characteristics of source, high yield and simple operation meet the requirements of drying the extract.
Donkey-hide gelatin raw powder is made from donkey-hide gelatin raw material by microwave vacuum expansion drying technology. It is simple in crushing process, fragrant in the mouth, and easy to dissolve in water. It is suitable for adding honey, milk, milk powder, black tea and other partners to make various kinds of powder
Fashion health tea.

During the drying process of donkey-hide gelatin paste, the evaporation temperature of water has a direct relationship with atmospheric pressure. The lower the atmospheric pressure, the lower the boiling point of water. At one atmospheric pressure, the boiling point of water is 100 ° C, and the true void is less than -0.098 trillion
At Pascal, the evaporation temperature of water is 20~30 ℃. Therefore, when the object is in a vacuum state, the moisture in it can evaporate at a lower temperature, making the object dry at a lower temperature.
Drying cost
The effective ingredient content of donkey-hide gelatin paste dried by MVD series microwave vacuum equipment does not change, which is higher than that of ordinary vacuum drying equipment, indicating that this drying method can effectively improve the quality of donkey-hide gelatin paste.
Low temperature+fast=high quality drying 1 kg of donkey-hide gelatin paste electricity charge: (calculated at 1 yuan per kilowatt hour)
It only costs 1.0 yuan of electricity (only half of the operating cost of the vacuum pump of the ordinary vacuum equipment), and 4.75 yuan of electricity for the ordinary vacuum equipment
Data comparison: drying of traditional donkey-hide gelatin paste
Oven drying temperature is high, time is long, quality is low, energy consumption is large, floor area is large
The vacuum drying temperature is higher, the time is longer, the quality is lower, the energy consumption is large, and the floor area is large
High spray drying temperature, short time, high quality, high energy consumption, large floor area
Microwave vacuum equipment covers a small area: only 35% (common vacuum drying equipment)
Large capacity: 1 set top 2-3 sets less investment: (under the same output) less than (ordinary vacuum drying equipment)
Conclusion:
More! Come on! OK! Province!
1. More - The output is much larger. One equipment can dry 10 kg of donkey-hide gelatin paste in one hour.
2. Fast - 40-60 minutes to dry
3. Good - good quality after drying
4. Provincial-provincial energy, investment and plant area
