Abstract: A process in which an aqueous solution of carbohydrate origin, eg. a wheat starch hydrolysate which contains a phospholipid and difficult-to-filter solid material is treated with a phospholipase enzyme prior to filtration is carried out by immobilising the phospholipase on or in the particles of a solid support such as an anion exchanger and agitating the particles in contact with the aqueous solution, the agitation preferably being effected by the upward movement of the aqueous solution through a column or bed of the particles.

Abstract: The aim of the invention is to make it possible to vary independently of each other, i.e. better and more freely, the basic parameters in the design of a squeegee used as a flexible-plate doctor blade in a coating-material spreading device. These parameters may include the length of the chamfered surface in contact with the surface to be coated, the resistance to bending strain parallel to the spreading edge of the blade and the resistance to bending strain at right angles to the spreading edge of the blade. This aim is achieved by virtue of the fact that the flexible-blade doctor blade (squeegee) proposed does not have a constant thickness but is made up of two or more different cross-sections with steps parallel to the dosing edge (8), thus giving the flat sides of the doctor blade a substantially terrace-like structure. The blade may also have grooves parallel to the dosing edge.

Inventor: AIVARS GRINBERGS
IPC: A21D8/02
Filed: 1992-10-19
Abstract: This refers to the production of bread, particularly, that of rye-wheat bread through the method of flour parboiling. This method results in a prolonged storage time for rye-wheat bread products as well as improving its organoleptic qualities, and preserving the products' qualities throughout the storage period. This method for the production of rye-wheat bread products involves the preparation of parboiled wheat flour and white rye malt, the cooling of the parboiled flour, the preparation of yeast, the kneading of dough, the division of the dough into semi-finished products, and the leavening of semi-finished products, and finally the formation and baking of the products. According to this method, the wheat flour before parboiling must be taken in the amount of 25-30% of the total quantity of flour, and 4.5-5.5% rye flour must be added to the yeast.

Abstract: A lining board (1) has a lining skin (2) and a support (4) that supports the skin at the side opposite to the concrete and if required marginal bars (3) that extend in an approximately parallel direction to the supports (4). Adjacent lining boards (1) may be coupled and joined to each other. The supports (4) have an approximately U-shaped cross section. The legs (5) of the U extend away from each other on a U cross-bar (6) and their free ends, where their mutual distance is the largest, are provided with diverging fastening flanges (7) for joining them to the lining skin (2). In order to extend the lining board at least on one side in the same direction as the longitudinal extension of the support (4), each support (4) consists of two parts or sections (4a and 4b) adjustable in relation to each other in the longitudinal direction and which overlap at least in one overlapping area. The angle of inclination formed by the legs of the inner support section (4b) and the lining skin (2) at the inner side of its cross section is blunter or larger than the corresponding angle of the overlapping support section (4a), or the angle between both legs of the inner support section (4b) is sharper than the corresponding angle between the legs (5) of the outer support section (4a). The angles are selected so that when the cross-bars (6) of the U lie next to each other the clearance between the U-legs (5) of the inner support section (4b) at the lining skin (2) is smaller than the clearance at the outer support section (4a) in the same spot by approximately the total width of the diverging fastening flanges (7), so that the fastening flanges (7) of both support sections lie next to each other in the same plane when the lining skin (2) is even.
