Title: Jet pump for conveying powders - arranged with injectors at predetermined angles to the pump axis
Inventor: TARJAN IVAN PROF DR
IPC: B01F5/04
Filed: 1976-03-03
Abstract: The block free jet pump for conveying of solids in a stream of gas or liquid, in which the conveying medium enters the pumping chamber through a series of injector nozzles arranged at pre-determined angles to the main axis. Used for the transportation of dry powdery materials such as sand, fly ash or powdered coal, using either a liquid or a gas stream. Compared with conventional jet pumping equipment, the pump is not subject to blockages, operates at high frequency and can develop heads of up to 300 M. In the wall of the main pumping chamber there are a number of rows of injector nozzles, arranged at an angle of 10-50 deg. (pref. 30 deg.) to the axis of the pump. These are symmetrically disposed so that their axes intersect the main axis, and the points of intersection of the multiple rows are equi-distant. The cross-section of the pumping chamber diminishes progressively, either stagewise or continuously, from the suction to the discharge. The conveying fluid feeds through an annular chamber and thence through the injection nozzles into the main pumping chamber, the material to be conveyed entering at the base of the latter.

Title: Starch prodn. without dust formation - by wetting the starting material and immediately wet grinding it before separating the starch
Inventor: SCHMIDT PAUL
IPC: C08B30/04
Filed: 1976-07-31
Abstract: Starches are recovered from dry or dried fruit, roots etc. The coarsely comminuted material is wetted with water for a short time and the non-swollen material then wet ground. The suspension is then treated with SO2 or another reductant, the pH adjusted to a value depending on the type of the material and the starch recovered from the dissolved substances by known techniques. The material can be wetted as it comes off the transporter thereby eliminating dust formation. The wetted material is then ground before any swelling can start so that swelling only takes place after grinding leading to faster and easier subsequent sepn. and recovery of the starch and by-prods. The process is suitably used in (sub)tropical climates and their starting materials (e.g. tapioca).
