In fine milling, product accumulates in and on corners, edges, recesses, and shaft bushings. The only way to dislodge these residues is by using large amounts of cleansers. These factors were taken into account in the design of the ConiWitt conical sieve mill. The ConiWitt is also now available in CIP design. Where solid residues are effectively bonded and removed due to optimized surfaces.
The most important goal in the designing of the ConiWitt was a shape free of dead spaces. In order to achieve this goal, Frewitt opted for the monoblock design. The milling head consists of a monoblock with high quality surfaces (most of which are perpendicular) and a rounded drive and driveshaft. All metal contact surfaces of the CIP model are sealed off from the milling chamber with O-rings. The transitions between the rotor and the shaft, the conical sieve and the bevel gear, and the conical sieve insert and the housing are hermetically sealed. The seals do not interfere with dismantling/installing the sieve and rotor. The sieve and rotor are just as easy to change in the CIP model as they are in the standard model.
The CIP jets ensure thorough coverage of all parts and surfaces of the milling head with the washing fluid, which bonds to solid residues so that they can be rinsed away. A controlled cleaning process is ensured by the precise setting and regulation of pressure, flow volume, and flow velocity.
The Frewitt conical sieve mill is equipped to allow the customer to choose either WIP or CIP cleaning. CIP cleaning, however, does not include sterilization. If a given procedure requires sterilization, however, the customer can manually dismantle the milling head in two easy steps and sterilize it in an autoclave.
To this end! Frewitt confirmed the faultless cleanability of the ConiWitt with the riboflavin wetting test for low germ count or sterile process engineering. The documented test result confirms the design conception of the ConiWitt.
