DE3425051A1 - Intensive mains scouring unit for grains - Google Patents

Abstract

The invention relates to an intensive mains scouring unit for grains, preferably wheat and rye. The aim is to develop a machine which achieves a high, controllable working effect with minimum use of material and energy and in a simple manner requiring little servicing and maintenance. This is made possible according to the invention in that grain distributing and grain accelerating elements, water atomising elements, damming, processing and compression elements are arranged on a rotor. Enclosing this at a distance, a water-tight working casing, which can be opened when required, radially delimits the processing chamber, in which an intensive swirling of mains water and a curtain of grain takes place in the upper region and an automatic damming of material arises in the lower region, leading to further mechanical distribution and working-in of the mains water into the grain mixture. The working effect can be adjusted with respect to wetting-out or bran stripping by the metered water introduction, the adjustable damming effect, and the use of different rotating or stationary working elements connected to the casing. The stream of processed grain flows out downwards through a discharge hopper. <IMAGE>

Intensive mesh chopping unit for grain crops

The invention includes an intensive mesh scrubbing unit for grains ; preferably for intensive netting, wet washing and / or wet soling of rye, wheat or other grains for the production of flour and similar products.

The intensive net scrub unit is mainly used in flour mills used.

Various network devices are known which are located in their different constructional design by the chosen principle of action.

Gravity moving downwards. Below the acceleration plate X is a water atomization plate for rotating the water. When the water passes through the fastening area of the acceleration plate, a first breakdown of the water into droplets takes place. When the droplets are placed on the underside of the upper plate and the bowl of the lower plate, a further acceleration takes place, so that the atomized water is sprayed into the sole egg in a strip. This ensures that the network water is largely distributed over the grains. The Netzwa3ner is supplied in a pressure-free manner by means of a Stollvontil and a flow meter. A flow control at the intake of the intensive net scrubbing unit gives a signal to switch off the water dosing through a "solenoid valve" if the Gotreidestromes fail to appear. When combined with a moisture meter, an .automatic setting of the mains water volume to achieve the desired final moisture level is achieved V / water atomization plates are arranged in the order below, compression, work and damming elements et v / a 45 ° relative to the horizontal, and the increase in the number of damming elements increases the damming effect. If the material flows through the processing area continuously, a column of material corresponding to the damming set is formed are employed against the stem elements, takes place ei ne additional compression of the good column. By changing the angle of inclination of the damming elements, the height of the cut column and thus the dwell time and intensity of the intensive emergency cooking process can be reduced. Because of the intensive movement of the work elements in the pent-up good, there is strong friction between the grains and on the work unit and the processing elements themselves, and thus an intensive incorporation of the Netzwansers. This effect increases, the higher the set estate, through the longer Vorwallzoit and!
