Hydroxypropyl cellulose (HPC), as an etherified derivative of cellulose, has many excellent properties, such as hydrophilicity, biocompatibility and degradability. It is widely used as thickeners, emulsifiers and stabilizers in the food field, as well as drug coating materials and sustained-release agents in the pharmaceutical field.

The filter washing and drying machine uses natural cellulose as raw material, removes impurities and non-cellulose components through pretreatment, and then generates hydroxypropyl cellulose crude product by alkali purification. Next, the coarse product enters MY filter washing and drying machine for pulping washing and drying. The machine is equipped with a high precision filter screen, a mixing paddle that can achieve a combination of lifting and positive and negative rotation, vacuum drying and automatic solid discharge valve. It can efficiently pulp and wash hydroxypropyl cellulose crude products, saving washing time and the amount of washing liquid. After filtration, the filter cake has a lower humidity, which helps shorten the drying time, ensure product quality, and save energy. In addition, MY filter washing and drying machine adopts closed operation, no waste gas and waste liquid, and the production environment is clean and tidy.

MY series closed pressure filter washing and drying machine has good adaptability, especially suitable for difficult to filter slurry and flammable, explosive, toxic, volatile and easily polluted materials. It integrates filtration, washing and drying operations, and is an ideal equipment for solid-liquid separation in pharmaceutical, pesticide, food, chemical, dye and other industrial sectors.

The technical advantages of MY series closed pressure filter washing and drying machine include:

- One machine multi-energy, set pulp, washing, filtration, drying functions in one, reduce costs, save money;

- Closed operation, especially suitable for toxic, harmful and contaminated materials, safe and reliable operation;

- Reduce product wastage and waste;

- PLC or computer automatic control to achieve a high degree of automation;
