| dc.description.abstract | The purpose of hydrothermal processing of grain is to change its initial technological properties in the direction ofstabilization and maintaining them at the optimal level for the further process of processing it into the final product - flour or cereals.The use of devices of continuous action allows the steaming process to become more efficient, while hydrothermal treatmentoccupies a special place in the technology of processing cereals, obtaining them high consumer properties. The analysis of designs ofdevices of continuous action, shows that the most widespread have devices of horizontal type where the main working body of thesteamer has functions of transportation and hashing. This design allows to achieve uniformity of steaming during processing of theproduct. To achieve a flexible change in the exposure of steaming, it is proposed to introduce a two-stage variator in the drive of theworking body, which will significantly change the steaming time and use the apparatus for steaming more different crops, and toensure a constant set steam pressure the design of which allows to carry out these operations without pressure losses. In the two-stageversion of the variator, the rotation from its drive shaft by means of a V-belt is transmitted to the intermediate shaft, and from it bymeans of an additional V-belt to the main working shaft. The gear ratio is adjusted by turning the glasses and their synchronous shiftin the axial direction.At the same time there is a simultaneous movement of movable conical disks, transfer of a V-belt and anadditional V-belt to other diameters. We use sluice gates with a flat sealing surface and a fluoroplastic gasket to supply grain to theworking chamber under pressure and unload it. This design allows the most effective sealing of the working chamber under pressureand to maintain the working pressure within the specified limits, with continuous loading and unloading of the device. Thecalculations show the feasibility and efficiency of modernization of the steamer by ensuring the tightness of the unloader and theuniformity of the speed of the product processed in the working chamber by using a two-stage gearbox or drive motor with afrequency converter. | |
