Rotary vane vacuum pump in sugar making process

Why is the application of rotary vane vacuum pump in sugar making process so important? In sugar making, vacuum plays an indispensable role in the sugar making process. However, in the sugar industry, the efficiency of vacuum acquisition is often low due to the unsatisfactory condensation effect, which affects the production efficiency and effect of sugar production. A high efficiency condenser with 90% condensing effect is used together with rotary vane vacuum pump, which makes the vacuum effect more ideal. EVP vacuum pump manufacturers through this article to introduce the sugar production process, the role of rotary vacuum pump.

What are the important steps in the sugar making process?

One of the steps in the sugar making process is drying. Generally speaking, the white granulated sugar discharged from the centrifuge also contains 0.5% – 1.5% moisture, which must be fully dried and cooled before packaging and storage. Its principle is to remove the trace moisture contained in the material at a temperature lower than the boiling point of water. The drying of granulated sugar basically takes air as the medium, which makes the air flow through the surface of granulated sugar, so as to take away the water contained in the sugar. In other words, the drying of granulated sugar is the process of water diffusing into the air. Rotary vane vacuum pump vacuum drying is a kind of drying method that materials are placed under negative pressure and reach the boiling point under negative pressure by heating properly or by cooling to make the materials solidify and then dry through the melting point. It is a method of extracting air in a closed container, decompressing and drying.

Under normal pressure, the color, aroma, taste and nutritional components of materials will be lost to a certain extent due to the heating of materials. If the vacuum drying method is adopted, because of the isolation of air under negative pressure, some materials which are prone to oxidation and other chemical changes during the drying process can better maintain their original characteristics and reduce the loss of quality. Vacuum drying is to place the dried food materials in an airtight drying chamber. While vacuumizing with the vacuum system, the dried materials are heated continuously, so that the moisture inside the materials diffuses to the surface through the pressure difference or concentration difference. The water molecules gain enough kinetic energy on the surface of the materials and escape to the low-pressure air in the vacuum chamber after overcoming the attraction between the molecules, So it is removed by vacuum pump.

In this process, the raw sugar solution was filtered and purified by multi-layer nanofiltration membrane with rotary vane vacuum pump, and then evaporated and crystallized to produce high-quality white granulated sugar with rich natural flavor. The whole process is a pure physical process without the participation of sulfur, lime, phosphoric acid and other compounds in the conventional production process. The process is applicable to a wide range of applications. The raw material of the process can be sugarcane juice, raw sugar, crude sugar solution or even waste molasses. Because there is no additive in the whole process of manufacturing, the white granulated sugar has high safety, and can completely eliminate the pollution of filter mud and waste molasses by-products in comprehensive utilization, which has good environmental benefits.

The rotary vane vacuum pump has been applied in the sugar industry for a period of time, and has been highly praised by the users in the sugar industry. Before the arrival of the new opening period, the high-efficiency condenser is favored by the sugar industry users again. The high-efficiency condenser and the rotary vane vacuum pump are used together to improve the production efficiency. This means that sugar industry will bid farewell to chemical auxiliary materials such as sulfur, phosphoric acid and lime, and realize pure physical process production.
