PharmTech's monthly newsletter, Equipment and Processing Report, reviews the Editor's Picks for the November 2010 edition from BinMaster and Silverson Machines.
Process connection provides long service life
BinMaster’s (Lincoln, NE) stainless-steel process connection for the BMRX and MAXIMA+ rotary level indicators is designed especially to withstand corrosive materials. The device fits into existing 1.25- and 1.5-in. standard process connections and can be installed easily without special fittings or adapters. The solid stainless-steel construction of the process connection is designed to be stronger and to last longer than the normal connection on a standard rotary, according to the company. Rotaries are appropriate for detecting the level of material in bins, hoppers, and silos to ensure continuous operation or manage inventory.
Operators can use a rotary with the process connection with three-vane, two-vane, insertable, and bayonet-style stainless-steel paddles. BinMaster’s insertable paddle collapses to fit through a standard 1.5- or 1.25-in. opening, and the rotary can be installed without entering the bin. Employees choose the proper paddle according to the type and weight of the material.
Machine produces agglomerate-free mixes
The Flashmix from Silverson Machines (East Longmeadow, MA) is a high-shear mixer designed for powder–liquid mixing. The machine brings liquids and powders together in the high-shear region of its precision-engineered rotor–stator workhead assembly, thus subjecting materials to focused high shear to create an agglomerate-free dispersion. The mixer’s modified rotor–stator workhead also boosts its pumping performance, thus eliminating the need for an additional pump.
The Flashmix machine wets out powders at rates as high as 250 lb/min. Operators do not have to adjust the mixer’s valves to balance powder incorporation and liquid-flow rates as viscosity rises. The mixer incorporates a clean-in-place loop intended to simplify operation. Users can install the machine in an existing process easily, and the unit has a lower power requirement than competing mixers because it does not need an additional feed pump.
