Vacuum system in soybean oil refining and processing

In the process of soybean oil refining, steam consumption accounts for a large proportion of the driving force cost. The energy saving and emission reduction of soybean oil refining workshop, especially the reduction of steam consumption, has become the technical importance for soybean oil companies to control the cost. Small and medium-sized refineries can use roots vacuum pump vacuum unit, large and medium-sized refineries can choose to apply vacuum system to reduce steam consumption and product cost. Next, we will introduce in detail the technological process of soybean oil concentrate and the application of vacuum system in the refining process.

Soybean oil refining belongs to the level of soybean oil production and processing. Soybean oil production and processing refers to the whole process of producing and processing crude oil obtained by different types and refining methods into various types and specifications of soybean oil commodities. In addition to soybean oil refining, it also includes modified materials, blending, hydrolysis reaction polymers, etc. Crude soybean oil is called crude oil, which is extracted by pressing, leaching and water substitution. The key components of crude oil are Vaseline triates and compounds. The crude oil contains non Vaseline triates, commonly known as “residue”.

Application of vacuum system in soybean oil refining
Soybean oil refining includes the following process flow:
1. The way to remove the residue is by mechanical floating.
2. Open glue: it can be solidified, acid refined and alkali refined.
3. Deacidification: can be refined with alkali, steam and steam distillation.
4. Discoloration: absorb with clay.
5. Dewaxing: it is usually removed by ultra-low temperature crystal.
6. Deodorization: steam distillation of tap water.

In the deodorization stage, the vapor from the oleic acid trap is pumped away by the vacuum system and cooled to the hot well together with the working steam of the vacuum system. Then, according to the pump, it will be sent to the hot river water / refrigerant cooling tower for cooling and cooling after cooling and cooling.

The principle of vacuum system is to start the main mechanical pump group of the system software to start working until the internal vacuum value of similar vacuum tank reaches the upper limit value set, the mechanical pump stops running automatically, and the vacuum pump in the central government vacuum system is maintained by the vacuum pump check valve on the pipeline. If the internal vacuum value of similar vacuum tank is required to be reduced and less than the set lower limit value, the reserved mechanical pump set will start automatically. Thus, the vacuum value of the vacuum system can be kept stable, considering the requirements of production and manufacturing.

Compared with the three deodorization methods, such as spray air cooling system software, ultra-low temperature caustic soda solution cooling vacuum system and pre deodorization vacuum system, the vacuum pump deodorization process has obvious advantages

1. Energy consumption level: without the application of multi-level steam jet pump, air cooler and other equipment, the required steam working pressure is reduced, and the steam consumption is also greatly reduced; basically, there is no refrigeration cooling circulating water and no refrigeration circulating pump.
2. Environmental protection: basically no sewage discharge, easy to separate out and solve; finally, the discharged steam almost does not contain volatile chemicals, no odor.
3. Practical operation: the vacuum pump is stable, easy to operate, good adjustability, high level of automation technology and reliable, suitable for the requirements of variable gas supply.
4. Maintenance level of Civil Engineering: it occupies a small indoor space, which is very easy to get close to, and the maintenance labor of management method is small.

Vacuum pump system is one of the main applications in the refining process. In addition, it is also used in the deodorization system software of soybean oil refining production line, which reduces the product cost and obtains excellent economic benefits. In addition, it is also suitable for large-scale soybean oil refining production line. The application of vacuum system in grain processing machinery is also very applicable.
