Working Principle
Vertical Ribbon Mixer
consists of one ribbon shaft, vertical shape vessel, drive unit, cleanout door and chopper. It is a new developed mixer which is popularly used in food and pharmaceutical industry because of simple structure, easy cleaning and clean discharging. The ribbon agitator will lift the material from bottom of mixer and fall down by gravity. Furthermore, there is chopper on side of vessel to break agglomerates during mixing. The cleanout door on side will be useful for worker to clean everywhere inside mixer. Due to all drive unit part is designed at outside of mixer, there is no possible of oil leakage into mixer.
The thermal energy needed for drying is introduced into the product through a heated jacket that can be heated by various media including steam, hot oil and water. The jacket provides rapid distribution of heat into the product in combination with efficient mixing.
The vacuum inside the dryer allows vapor to be removed at low temperatures, which makes the conical screw vacuum dryer ideal for drying heat-sensitive products. The vapors are removed through a dust filter fitted on top of the vessel. This then prevents the dust from penetrating into the vacuum system.
The conical screw vacuum dryer is fitted with a condenser with a receptacle for recovering solvents. This condenser can be installed before the vacuum pump, or after it, depending on the characteristics of the solvents.
The moisture content of the product can be controlled by monitoring the weight of condensate or using the Vortex sampler for taking samples from the product inside the dryer under vacuum.
