freeze-drying equipment

Descriptions of freeze-drying equipment:

    The freeze drying technology is the most advanced food dehydration processing technology at present. The freeze-dried food processed by this technology has long expiration date, good reconstitution property, color, aroma, taste and nutrition. The volume and shape of the food is essentially constant, showing a spongy state without drying shrinkage phenomenon. It can be used in vegetables, fruits, condiments, aquatic products, biological products, medicines, beverages, specimens, and other fields.

Features of freeze-drying equipment:

1.The vacuum system uses gland pump and oil sealed pump compound mode. At first, the high power oil sealed pump quickly drainages the air. Then the vacuum low power gland pump works to pump the water vapor and reduce energy consumption. Otherwise, the poor drainage performance of oil sealed pump will make the water vapor concentrated to lead to pump oil emulsification metamorphism, which will further destabilize the vacuum stability of the system.

2.Closed circulating water system uses three way control valve to automatically regulate the heating amount of water cycle system and precisely control the temperature of heating plate. What’s more, nitrogen automatic pressure control device can keep the operating temperature of the hot water at 120℃.

3.Post and side type water filling cryofocus has short access, small resistance, fluent water vapor channel, uniform water filling effect, and high water filling efficiency. The water filling cryofocus adopts ammonia single-phase circulation cooling way, with good cooling liquid supply stability and easy operation.

Main functions of freeze-drying equipment:

1.It has pre-cooling function and the products can be preserved by nitrogen gas or inert gas after drying.

2.International famous brand compressor is efficient with low noise. High quality vacuum pump has fast speed and low noise.

3.The freeze-dried automatic control system has procedural programming system that can control the processes from freeze-drying to defrosting.

4.The plate layer is welded by international advanced technology and it won’t leak.

5.The system can automatically test the freeze-dried end point after analytic drying stage to ensure that the material moisture content reaches the standard requirements.

6.Vacuum degree adjustment during sublimation and drying process can avoid special material foaming and bottle blowing problems and speed up the efficiency of the freeze-drying.

7.There are slow, middle, and fast three backfill modes. It avoids effective material loss blowing by inflating to granular and flocculent substances after freeze-drying.

8.Large size industrial touch screen has good man-machine interactivity and is easy to operate. The monitoring system can monitor the system temperature and vacuum degree in real time at 50ms for each time.

9.Formula storage capability can preserve 2000 groups of fixed or user-defined freeze-drying process recipe. The optional PC remote monitoring system can monitor the equipment running status with 1.5km farthest monitoring distance.

10.The eutectic point test function and process data recording system are optional. The calibration function can calibrate the temperature and vacuum degree to ensure the accuracy of measurement value for a long time. And the freeze-drying curve query function can check temperature and vacuum degree curve to make process optimization and freeze-dried effect validation easier.
