Description

The utility model relates to the processing branch of agricultural production and can be used in the production of feed, preparation of grain for grinding, beer malt and oilseeds for processing and storage.

Various devices are now known for treating cereals, beer malt, pulses and oilseeds prior to storage or processing.

A device for ultrasonic processing of grain is known, which includes a receiving device, a volumetric sonication chamber, an ultrasonic piezoelectric transducer of the through-flow type, a settling chamber, a branch pipe for removing light impurities, a water outlet, the lower part of which is made of a steel mesh, a screw for transporting cleaned grain and a screw for the transportation of raw materials, installed in the sound chamber, which consists in cleaning the shell from mineral impurities and traces of micro-contamination and moistening it to conditional parameters. (Patent for utility model No. 126963, IPC B02B 5/00, publ. 20.04.2013, bul. No. 11).

The disadvantage of the known solution is that the grain supplied for moistening has different initial moisture content and when it is moistened in the screw mechanism, it is impossible to achieve the standard moisture indicator without adjusting the time range of the grain in the chamber equipped with a piezoelectric transducer of the pass-through type. Another disadvantage is that the device does not have a liquid heating system necessary to intensify the treatment process.

A device for post-harvest processing of grain before laying for long-term storage is known (Patent for invention No. 2084117, MPKA01F 25/00, publ .: 20.07.1997), containing a vertical contact chamber with means for loading, distributing and unloading grain, a propionic supply source acid and the means for spraying it into the contact chamber, characterized in that it is equipped with a water supply source, and the spraying means is made in the form of a housing with water and propionic acid supply pipes, each of which is equipped with a membrane with nozzle holes installed at the outlet, installed at the outlet of the housing a baffle with a coaxial propionic acid supply branch pipe and a rod concentrator of longitudinal vibrations, one end of which is rigidly fixed to the nozzle membrane of the propionic acid supply branch pipe, and the second is placed flush in the housing baffle opening with the formation of an annular gap.

The disadvantage of this design is that the device is intended only for stirring an aqueous solution of propionic acid by ultrasonic spraying during fungostatic processing of grain during storage. However, with ultrasonic spraying of an aqueous solution of propionic acid, ultrasound does not have time to affect the cell membranes of the surface microflora of the grain.

A device for processing grain is known, comprising a vertical cylindrical body, equipped with a loading chute in the upper part of the body, liquid supply and outlet pipes, an unloading pipe and an unloading device, a removable bottom, ultrasonic emitters, and a mixer placed inside the housing, characterized in that the ultrasonic emitters are located in a cylindrical body diagonally in the opposite direction relative to each other with an angle of inclination α equal to 30 ° -40 °, in addition, the liquid outlet is equipped with a filter (Patent for utility model No. 130519, IPC B02B 1/04, published: 27.07. 2013 bul. No. 21).

However, this device is intended for periodic processing of grain with constant unloading of the processed and loading of a new batch for processing, leading to the impossibility of automating the process and the need for constant manual work; it has a mechanical stirrer that does not allow intensive and uniform mixing for sonication of the entire mass of grain. "Dead untreated zones" are formed in the suspension, which worsen the quality of processing. The absence of a liquid heating system impairs the process of mass transfer in the channels and pores of the grain during the inactivation of trypsin inhibitors and during the cleaning of the grain shell from mineral contamination and traces of insect infestation. The installation has low resource-saving indicators of water consumption and there is also no system for pre-squeezing the processed grain.

The closest to the claimed utility model is a device for preparing malt for producing beer wort (Inventor's certificate for invention No. 309609, IPC C12C 1/02, publ. 03/21/1972, bull.11). The weighed malt enters the collector of the installation by gravity along with water, in which the mixture is treated with ultrasound, after which the mass is continuously fed to a closed screw filled with water. In it, it is mixed for 10 minutes and in the stream goes directly to the crusher. The drained water can be returned to the lock and used during mashing.

This method is intended only to accelerate humidification when preparing beer malt for processing, moreover, ultrasonic processing occurs in the collector, which complicates the access of ultrasonic vibrations to the processed object, and a closed screw mechanism is used as a low-productivity mechanism for promoting malt with hydrodynamic treatment with water, which to achieve 30% moisture will require an increase in its length. The lack of systems for preheating the liquid and squeezing malt leads to an increase in time and a deterioration in the quality of processing.

The technical task of the utility model is to increase the efficiency of the cleaning process of grain, beer malt, legumes and oilseeds.

The technical result of the utility model is the intensification of the processes of washing, disinfection, moistening of grain, beer malt, legumes and oilseeds, as well as inactivation of anti-nutrients in soybean grain.

The technical result of the claimed utility model is achieved by the fact that the device for processing grain, legumes, malt and oilseeds contains a horizontal screw conveyor with variable (adjustable) screw rotation frequency and the angle of inclination of the screw housing, ultrasonic emitters installed at a certain working distance of the screw housing, cable heater for heating the processed suspension to the temperature set for the processed culture, automated and regulated water supply and a system for pre-squeezing the processed material.

FIG. Figure 1 shows a diagram of a device for processing grain (general view). Figure 2 - view A, viewing windows. The device works as follows. The grain is loaded into the hopper 1 with a volume of 0.1 m ³ and due to the rotation of the auger 4 moves upward along the body 2 of the installation. Ultrasonic processing of grain is carried out by two ultrasonic emitters 5, installed at different levels of the body, at a distance of 1500 mm from each other. To carry out the process of ultrasonic processing of grain through the nozzle 6, water is supplied to the body in the amount necessary to keep the level of wet grain above the level of the upper ultrasonic emitter. Control of the water filling level is carried out by two inspection windows 10, installed on opposite sides of the body opposite each other (for visual control of the level "through"). Grain and seeds are subjected to ultrasound processing during the time it is in the operating range of ultrasound emitters. The required range of action of ultrasound radiation on the processed suspension is set by the rotational speed and the pitch of the screw.

To remove water from the grain (squeezing) after ultrasonic treatment, a perforated partition 7 is installed in the housing, through which the grain is pressed by the auger, thereby making its first squeezing. Behind the perforated partition, the body has a conical narrowing, passing through which, due to the compaction of the grain, its second squeezing is performed. The squeezed-out water is removed through the nozzles with a mesh 9: one of which is installed in front of the perforated partition, the second in front of the cone of the body. Further, the dewatered grain is discharged through the discharge nozzle 8.

In order to intensify the process of ultrasonic processing of grain and seeds, a part of the installation body (between the ultrasonic emitters) is equipped with a cable heater 14. The heating temperature of the cable is regulated from the control cabinet and controlled by a temperature sensor 11 mounted in a protective shield with a heater 15.

The body is fixed on two posts: fixed 12 and adjustable 13, with the help of which the angle of inclination of the installation body is adjusted.

The grain loading hopper has two versions:

1. For positioning the unit body at an angle of 15-30 °.

2. For positioning the unit body at an angle of 35-45 °.

The useful model allows, when processing grain, legumes, malt and oilseeds, to intensify the process of washing, disinfecting, moistening and inactivating nutrient substances due to intensive mixing with a screw, acting with low-frequency ultrasound. The processing time is regulated depending on the angle of installation of the utility model housing and the rotation speed of the auger.
