Plough Shear Mixer is the most widely used for multiple application such as mixing, coating, drying and reaction. In different places, the name of plough shear mixer is different. In Europe, people like to call it Plough Share Mixer. In US, people like to call Plow Mixer. In Asia, people like to call Plough Shear Mixer. Anyway, the principle is the same which is making material in fluidizing action with high speed to get homogeneity mixing in short time.Ruizhi got an order from a Thailand customer who produce food product. This customer need mixer for drying function to make 20% moisture product into 3% water content dry powder. The process is as following:
A. Firstly, the worker feed raw material into mixer by manual before starting the mixer.
B. Then start the mixer slowing first with inverter control.
C. Using heating jacket to increase temperature inside the mxier by 120 degree.
D. Vacuum pump to connect with mixer to extract steam vapor out to increase drying effect.
E. After final drying, increase the speed of mixer to increase drying speed.
According to our experience, the drive unit must be strong enough for drying mixer because the material will be sticky during drying period, especially in the middle stage of drying because the material is in semi-dry status. Furthermore, the shaft speed should be variable control because the
Plough Shear Mixer needn’t use high speed in the early and middle stage during drying. After final but before totally dried, the shaft will be fast to increase drying speed.
As for heating medium, it could be steam, hot water or hot oil but steam and hot oil is better. The jacket will be design according to the pressure of process. Insulation layer is a must in order to keep temperature and avoid heat hurt outside.
As for vacuum filter, we shall take consideration during vacuum pump extract vapor out. The filter will avoid the fine powder material take out together with vapor and block the nozzle of vacuum pump.
Regarding seal part, packing seal is necessary for normal drying. If there is much pressure inside the vessel, mechanical seal will be a better choice but we must pay highly attention on mechanical seal because not all of the product can be suitable to use mechanical seal.
Generally speaking, the whole drying period is at least 1-2 hours depending on the water content of raw material. The first and middle stage will be faster than final stage because the water component is hard to be dried at final stage.
Nowadays, more and more customers prefer using one machine to fulfill multiple functions. Plough Shear Mixer is the best choice to be designed in different options. Vortex is willing to share our experience to every customers for helping them to get the right mixing solution.
