(54) DEVICE FOR MOISTURIZING GRAIN

I

The invention relates to the food industry and is intended for the processing of grain.

A device for moistening grain is known, which comprises a horizontally mounted cylindrical chamber with loading and unloading devices, a metering mechanism and a rotor mounted inside the chamber in which the blades 1 are longitudinally mounted.

However, this device does not evenly wet the surface of the grain, which leads to a decrease in the quality of the grain prepared for grinding.

The aim of the invention is to ensure uniform wetting of the surface of the grain.

The goal is achieved by the fact that in the proposed device the rotor is hollow and its external diameter is 20-50% of the diameter of the gauge, and the area of the rotor occupied by the blades is 3-50% of its total area.

The blades are made with a flat profile.

The 1 stitch is made with or oval profile.

The boot device is equipped with LiiiieKOM.

The rotor blades in the area of the boot device are installed at an angle of 50--85 ° C.

A part of the blades is installed under the straight gage to the rotor axis, and a part is at an angle from 45 ° to 80 ° to the rotor axis.

The profile of the blades at the boot device is made flat, and on the rest of the parts round or oval.

Loading and unloading devices are located tangentially to the chamber.

FIG. 1 shows a device for moistening grain, with a section of the chamber; in fig. 2 — part of the device on an enlarged scale in the area of the loading device; in fig. 3 - the same, cross section; in fig. 4 and 5 are embodiments of the device; in fig. 6 is a section A-A in FIG. five; in fig. 7 is a section BB in FIG. five; in fig. 8 and 9 are embodiments of the rotor.

The device contains a horizontally mounted cylindrical chamber G with a loading device 2, a discharge device 3 and a rotor 4, and also a dosing mechanism. The dosing mechanism contains a grain quantity sensor 5 with a contact pad 6 and a lever 7 located in the loading device 2, a water flow controller 8, a measuring tank 9, pipelines 10 and 11, and a water dispenser 12. Moreover, the nebulizer 12 can be stirred, both in the loading device 2 and 2 (Fig. 1 and 4), and in the chamber 1 (Fig. 5). Loading and unloading devices 2 and 3 are located tangentially to the cylindrical surface of chamber I.

The rotor 4 is made hollow, and its first diameter is 20-50% of the diameter of the chamber 1 in which it is placed. Blades 13 are longitudinally mounted on the rotor, which can also have a different profile and position relative to the rotor axis. So the blades 13 can be BE: .1 Filled with a flat profile (Fig. 1, 5 and 8), and also with a round (Fig. 4) or oval (Fig. 9) profile. In order to provide longitudinal movement of grain at a certain speed in the tank 1, where the blades 13 are installed at a zero or small angle of lift (Fig. 5 and 9), the loading device 2 is equipped with a uiFie 14. A screw 14 is mounted on the rotor 4, and the grain drops from the loading device on the povopa blade.

In addition, the profile of the blades 13 of the loading device 2 can be made by a flat. The rest of the blades can be made round or oval (Fig. 4). Moreover, the blades 13 with a flat profile m are installed at an angle of 50-85 ° to ensure the transportation of grain along chamber 1.

In addition, on one rotor part of the blades 3 can be installed at a right angle, and the other part at an angle from 45 to 80 ° to the rotor axis. Moreover, the transportation of grain in the chamber is provided by the second part of the blades.

The device works in the following way.

The grain through the loading device 2 is fed into the chamber 1, mine contact pad 6 of the sensor 5, which measures the amount of loaded grain. As a result, the dosage mechanism produces a necessary dose of water, proportional to the amount of grain. Moreover, water is supplied to the chamber of the loading device 2 or directly to the chamber 1. The grain fed to the chamber 1 is carried along it.

Shchekke 14 or lonast. 13, installed with a positive angle of elevation.

The grain flow transported in chamber 1 interacts with blades 13, which move the grains with water. The moistened flow of grain leaves the chamber 1 through the discharge device 37.

The proposed device allows to obtain a uniformly moistened grain with the necessary accurately dosed moisture content, which ensures high quality products made from this grain.
