The application process of plate and frame filter press in the Chinese patent medicine industry.
Plate and frame filter press is a kind of solid-liquid separation equipment widely used in various industries, and in the Chinese patent medicine industry, its application process also has certain particularity and necessity. This article will introduce the application process of plate and frame filter press in the Chinese patent medicine industry in detail.
1. Introduction. Plate and frame filter press is an efficient, energy-saving and environmentally friendly solid-liquid separation equipment, which is mainly used in the separation, purification and purification of solids and liquids in various industrial fields. It consists of a plurality of filter plates, through which the alternating arrangement of the filter plates forms a filter chamber and a filter cake chamber. During the filtration process, liquids pass through a channel in the middle of the filter plate, while solids are trapped in the cake chamber.
Second, the application process of plate and frame filter press in the Chinese patent medicine industry.
1.Preparation.
Before using a plate-and-frame filter press, there is some preparation that needs to be done. First of all, it is necessary to clean the residue inside the machine to ensure the cleanliness of the inside of the machine. Secondly, check whether the filter cloth is in good condition and whether there is any damage or blockage. If there is a problem with the filter cloth, it needs to be replaced in time. Finally, according to the production needs, prepare the corresponding raw materials and auxiliary materials of Chinese patent medicine.
2.Mix and stir.
Mix the prepared raw materials and auxiliary materials of Chinese patent medicine together in a certain proportion, and then add an appropriate amount of water to stir. The purpose of agitation is to mix the raw materials well so that the subsequent filtration process is smoother.
3.Filtration.
The mixed raw materials are pumped into the filter chamber of the plate and frame filter press. During the filtration process, the liquid part is passed out of the channel in the middle of the filter plate through the filter cloth, while the solid part is trapped in the filter cake chamber. It should be noted that the pressure should be kept stable during the filtration process to ensure the filtration effect.
4.Pressing and washing.
After filtration, pressing and washing are required. The purpose of pressing is to squeeze the moisture out of the solid part of the cake chamber to make it drier. The purpose of washing is to completely remove the liquid remaining in the filter cake chamber to ensure the quality of the proprietary Chinese medicine.
5.Discharge and drying.
After pressing and washing, the discharge can begin. The solids in the cake chamber are removed from the machine and dried. The purpose of drying is to completely remove the moisture from the solid part for subsequent processing and use.
6.Finishing & Packing.
After drying, the raw materials of proprietary Chinese medicine can be sorted and packaged. During the finishing process, it is necessary to ensure that the purity and dryness of the raw materials meet the requirements. In the packaging process, strict operations need to be carried out in accordance with drug management regulations to ensure the quality and safety of drugs.
III. Conclusion. Plate and frame filter press plays an important role in the application process of the Chinese patent medicine industry. By using the plate and frame filter press, the efficient separation, purification and purification of the raw materials of proprietary Chinese medicine can be realized, so as to ensure the quality and safety of the drug. In practical application, reasonable operation and maintenance are required according to different production needs and process conditions to ensure the normal operation and prolong the service life of the machine.
