Description

The invention relates to a method for the mechanical and hydrothermal processing of cereal products, thanks to which their best use in the food and feed industry is achieved.

There is a method in which wheat flour is produced by mechanically decomposing starch by grinding a grain material in a roller mill with rolls having different speeds, leading from 8: 1 to 80 {1 1.

However, this method has a disadvantage, since starch decomposes only to a minor extent during the mechanical processing of the grain.

The aim of the invention is to increase the nutritional value of the feed due to the mechanical and hydrothermal effect on the grain by heating the grain more than by

This goal is achieved by the fact that grain products are fed into a shallow gap between two curved spheres, the relative speed of the grinding surfaces is chosen within 2 m / s, and the width of the gap between the walls |

equidistant from the narrowest point of the slot, choose between 8-13.5 mm.

Higher efficiency is achieved if the grain is subjected to thermal and hydrothermal treatment before being introduced into the grinding gap.

Apply p.1. Between two rolls of the same diameter of 400 mm, a crushing is created with a maximum igarina of 10.5 mm, measured at a length of 100 mm at an equidistant distance from the narrowest point of the grinding slot. The speed of a faster roll was 15 rpm, and a slower speed of 430 rpm at a mutual speed of grinding surfaces of about 12 m / s.

PRI mme R 2. Rotating at a speed of 175 rpm slower

The 20 roll has a diameter of .400 mm, rotating at a speed of 10.00 rpm, the more rapid roll has a diameter of 300 mm. The maximum width of the grinding gap, measured at a length of 100 mm

25 equidistant from the narrowest grinding gap, is 13.5 mm, the mutual speed of grinding surfaces is about 12 m / s.

The outer surfaces, of which the inner surface is 500 mm in diameter at 570 rpm, and jmHyTpeHHHH has an outer grinding surface in diameter of 200 mm at rpm; 1000 rpm, the width of the slit gap measured at 100 mm equidistant from the narrowest point of the grinding gap, is 8 mm, and the mutual speed of the grinding surfaces is about 15 m / s,

PRI me R 4. A roll with a diameter of 200 mm and a speed of 500 m / s has a relative speed of about 15.2 m / s with respect to the grinding surface. The length of the curved pressure grinding surface is 170 mm with a maximum slit width of 10 mm.

PRI me R 5, a grinding gap formed by a slow diameter roll. 400 mm with a speed of 175 rev / min and a faster roll with a diameter of .300 mm and with a speed of 1500 rpm without cooling, barley with a humidity of 13.9% is supplied, which immediately before this was irradiated with infrared rays for 30 seconds 132c kept at this temperature for another 60 s. When using the enzymatic method, the product was set to five times more decomposed starch / than in unprepared milling, barley.
