Working principle and maintenance measures of pulsating vacuum dryer

The pulsating vacuum dryer is a continuous low-temperature drying of materials in a vacuum state, and has a pulsation function during the drying process, and the vacuum degree is adjusted instantaneously at regular intervals, so that the drying state of the materials such as foaming is constantly changing, so as to achieve the purpose of rapid drying
.

The equipment is to heat and dry the inner layer board and the cabinet clips under vacuum conditions
.

The vacuum pump is used for dehumidification, so that a vacuum state is formed in the working chamber, the boiling point of water is reduced, a high drying rate can be obtained at a lower temperature, the heat is fully utilized, and no impurities are mixed in the drying process.
Static vacuum drying, so it will not cause damage to the shape of the dried material.
After the material is foamed, the foam is quickly broken by clean air, which meets the requirements of the new "GMP" specification
.

High-performance PLC is used for whole-process detection and control, the working pressure and temperature are automatically adjusted throughout the whole process, and the work report is output in real time for filing for future reference
.

Maintenance measures for pulsating vacuum dryer: 1.
In daily use, the necessary preparations should be carried out
.

It is necessary to check whether the connection between the bearing and the sealing part of each device is loose, the lubricating oil condition of each mechanical part, and whether the valve ports of each water, wind, and slurry pipe are in the required position, so as to prevent the parts from loosening and the absence of lubricating oil.
Failure, in the long run, shortens the service life of the equipment
.

2.
The vacuum drying equipment should use a steam jacket to indirectly heat the material and exhaust under high vacuum, but it cannot operate under high temperature conditions, or it cannot use materials that are easy to oxidize at high temperatures or materials that are easy to produce powder when drying, and Material drying operations where steam or solvent removed during drying must be recovered
.

3.
If the dryer is not used for a long time, care should be taken to clean all parts, especially the oven door sealing strip, to prevent aging
.

Close the door of the vacuum drying oven tightly
.

Note that please do not use liquids with strong acid and alkaline strength to clean, just use water to clean, after cleaning, you should pay attention to dry the water
.

　　The pulsating vacuum dryer is a low-temperature drying equipment designed for extracts with high sugar content, low temperature, easy overflow, easy foaming, and easy oxidation
.

The equipment can use steam, hot water, and electricity as heat sources, and can complete online cleaning or soaking cleaning functions
.

It solves the problems of low equipment efficiency and disconnection with the pharmaceutical production process for many years.
At present, it is an energy-saving replacement product with the functions of drying and cleaning
.

It solves the low drying efficiency of extract, which is 80% higher than that of traditional equipment; solves the phenomenon of material running and overflowing in material drying, adopts advanced technology to detect and use technology to deal with it; solves the problem of high energy consumption of equipment, and reduces the cost of traditional equipment by 50% above
