VACUUM SIEVING & CONVEYING OF SUGAR
|
The system consists of Cyclone Separator, Bag filter with Turbine Blower, and De-clogging arrangement, Structure stand, Bottom Butterfly valve at cyclone, Electrical control panel, pipe fittings, interconnecting pipes (options). It would be used to transfer powder from Siever discharge to Vertical Conical Blender.
PRINCIPLE OF OPERATION
The Scheme is a LEAN phase Conveying method. Actuation of the blower achieves a negative pressure in the entire system. Air is drawn into the Loop through the suction wand. High air velocity allows for simultaneous injection and conveying of materials, to the product disengagement chamber (CYCLONE SEPARATOR). The body of the equipment can be vacuumised and material is drawn in directly to Sugar Dissolving Vessel & any fines which are carried over gets trapped into the filter to the cyclone seperator. These are discharged either on a going basis or at the end of the transfer cycle. In the Cyclone, air separates from the product due to break in the conveying velocity. Timer controlled sequential operation of the discharge valve allows for
--Vacuum break
-- Filter De-clogging
-- Product / Dust &Fines Discharge
The cycle is repeated till desired quantity of material is dispensed. In the current scheme the product will be directly drawn into the body and the carry over dust/crystals will be entrapped in the Cyclone. Normally flexible wand is manually put into the Sugar crystal storage bin & under negative pressure, Sugar is withdrawn thru Siever into Dissolver. All fibrous & other extraneous particle are sieved into Siever.
The system consists of
- A vacuum conveying system utilizing Roots Blower, Modular construction equipment
- Jet Air Wand with Air regulating Damper
- Jet Air Wand fitted with stainless steel wire mesh to stop foreign particles entry in to process.
- Entire transfer through electro polished pipe with curvilinear bends and isolating valves both manual and pneumatically actuated.
- Flexible pipe in PVC food grade with SS wire. Piping from Cyclone separator to Blower is in non compliance of food grade material
- Suitable filters pleated 5 micron in the product unloading chamber, pulse jet type, for insitu separation of dust from conveying media
- Root blower to create negative pressure for material conveying.
