Carrageenan (Carrageen, CAS 9000-07-1), also known as carrageenan gum, carrageenan, gum Taicai Ireland, is a red algae from the ocean (including carrageenan genus Eucheuma genus fir algae genus collectively) polysaccharide extracted and sand (Brassicaceae), is a mixture of many substances, there is ι (iota), κ (Kappa ), λ (Lamda), μ (mu) four. 
Engineering principles:

        SZG series double cone rotating vacuum drier has double cone rotating tank, the tank in a vacuum state, to the jacket into the steam or hot water heating, heat through the tank wall contact with the wet material. Wet material after evaporation of water vapor absorbs heat through vacuum exhaust pipe is pumped. Since the tank body in a vacuum state, and the rotating of tank so that the material constant up and down, inside and outside the flip, it accelerated the drying rate of materials, improve drying efficiency, to achieve uniform drying purposes.
