The Pick "BX Series" Starch Jet Cooker is designed for use in paper mills and ethanol plants where high volumes of starch can be cooked in-line. The generous flow-through design assures negligible pressure drop in the slurry, and provides thorough cooking at a precisely controlled temperature.
The low velocity design minimizes mechanical shear of the starch granules... an important consideration for cooking most cationic starches.
These heaters can also perform "double duty." They are often used to pre-heat water which is then blended with the starch powder to form the initial slurry. The slurry is then pumped back through the same heater for final cooking.
These compact, non-plugging BX Starch Jet Cookers are available to process flow rates in excess of 1000 GPM.

The unique design of the Pick BX Starch Jet Cooker offers key advantages over other high-velocity venturi devices.
Starch flows through the heater without obstruction. This results in negligible pressure drop when handling high viscosity formulations.
Noise generation is significantly lower and pipe vibration virtually eliminated.
Non-shearing action provides uniform product consistency
This provides a “thorough cook” of starch granules yielding a better cooked product.
For preliminary heater selection use the following Sizing Formula. Next match the liquid flow rate to the appropriate pipe size. The selection should be verified by your local Pick Heater Rep or a Factory Sales Engineer.
Please contact us with questions.
(lb/hr)= 0.43 x flow(GPM) x ∆ T (ºF)
or
(kg/hr) = 0.092 x flow(LPM) x ∆ T (ºC)
Example: 200 GPM x 50ºF temperature rise x 0.43 = 4,300 lb/hr of steam. You would require a 6X50-3BX which has a maximum rated steam capacity of 5,000 lb/hr, and a maximum water flow rate of 500 GPM with welded flanged connections.
