Starch washing multicyclone system type PH - 1

Starch washing multicyclone system type PH For purification of starch slurries Application The multistage starch washing system purifies and concentrates the starch slurries obtained from various raw materials. The purification is done by countercurrent washing in six to twelve multicyclone stages, depending on the specific application. Working principle The multistage starch washing system comprises several multicyclone housings containing a number of internally manifolded cyclonettes. Each individual housing is fed with a separate pump,(see the simplified flow diagram on next page). The overflow of each housing is connected to the pump feeding the preceding housing in the system. The underflow of each housing is connected to the pump feeding the next housing in the system. In this way the underflow of each housing is diluted with the overflow of the next following housing, and is then fed to the following housing. By diluting the underflow of the next-to-last housing with fresh water, a countercurrent washing system is obtained in which the starch is repeatedly concentrated and diluted with an increasing portion of fresh water. The purified starch milk leaves the system concentrated, through the last housing's underflow. The wash water together with impurities and part of the starch leave the system through the first housing's overflow. Standard design The multistage starch washing system comprises housings in stainless steel with internally manifolded cyclonettes. The housings are equipped with removable front covers (bolted), and with flanged feed, overflow, and underflow connections. It also features centrifugal pumps in stainless steel, with mechanical seals. The interconnecting piping and the support frame are made in stainless steel. Advantages • Performance - The combined effect of dilution washing and high shear forces in the cyclonettes results in optimum washing efficiency. • Reliable Operation - absence of moving parts results in minimum wear and minimum downtime. • Easy to operate - required washing effect and underflow concentration are controlled by adjusting control valves. • Low maintenance cost. • CIP - easy to implement CIP.

Types and Sizes The multicyclone units type PH are available as single units, and as double units (two sets of cyclonettes arranged in parallel in one housing) and are available in the following sizes: Single units: PH-75, PH-95, PH-165, PH-230 Double units: PH-330, PH-460 PH-75 6.5 76 25 Pressure cyclonettes Capacity m3/h Capacity The recommended pressure drop between the feed pressure and the overflow pressure is 4.5-8.0 bar. With a pressure difference of 6.5 bar, and with a dry solid content of 19 % in the feed slurry, the approx. capacities for the various multicyclone unit sizes are:...
