Problems solved by technology
However, the general industrial centrifuge filter membrane is only enough to meet the cleaning requirements of general microcrystalline cellulose, but cannot meet the cleaning needs of nano-microcrystalline cellulose
Separation with ordinary microporous membranes has low efficiency and is easy to clog, making it difficult to meet the needs of industrial production.
In addition, simple washing and filtering requires a large amount of water, and post-processing consumes a lot of energy

The invention discloses a nanocrystalline cellulose lotion and spin-drying device. A material inlet and a cover body are positioned on the middle position of the upper cover of an outer shell; the upper cover of the outer shell is connected with the outer shell; a hollow fiber bundle is positioned on an inner cavity separation board; an inner fixing device is connected with an inner cavity; both a material feeding connection pipeline and the upper cover of the inner cavity are connected with the inner cavity; the water outlet slit of the inner cavity is positioned between the inner cavity and the separation board; a base is connected with the outer shell. According to the nanocrystalline cellulose lotion and the spin-drying device, defects in the traditional industry that certain devices which remove surface impurities of microcrystalline cellulose and the nanocrystalline cellulose by washing can be overcome. The device is divided into an inner cavity arranged material lotion area and an outer cavity water discharging area by the inner shell and the outer shell of the lotion device. In the washing process, substances, such as acid, salt and the like, in colloid penetrate through the hollow fiber bundle along with water to enter from the water outlet slit of the inner cavity and leave from the water outlet, and therefore, the nanocrystalline cellulose is intercepted.
Description
technical field [0001] The invention relates to a device for industrially cleaning and removing surface impurities of microcrystalline cellulose and nano-microcrystalline cellulose, in particular to a cleaning and drying device for nano-microcrystalline cellulose. Background technique [0002] Microcrystalline cellulose is the product of natural cellulose undergoing acid hydrolysis to the limit degree of polymerization. Its particle size is generally about 2-80um. It has the characteristics of low density, high modulus, renewable, degradable and wide sources. It is widely used in food and medicine because of its excellent characteristics such as odorless, tasteless, non-toxic, and non-irritating. At the same time, it can also be widely used as a reinforcing agent for composite materials to improve the performance of materials. Nanocrystalline cellulose is the product of hydrolysis of cellulose. It is a very small particle of cellulose. The rigid rod-shaped cellulose with a d...
