Unprocessed grain pretreatment system for grain postproduction service center

Abstract

The invention relates to an unprocessed grain pretreatment system for a grain postproduction service center. The unprocessed grain pretreatment system comprises an unprocessed grain cleaning system, aclean material storage system, a fluid bed drying system, a stoving system, a conveying system, a ventilation dust removing system, an electrical monitoring system and a PLC control system. Accordingto the unprocessed grain pretreatment system for the grain postproduction service center, under the control effect of the PLC control system, the continuous working modes of cleaning, drying, stoving, conveying and putting in storage of an 'unprocessed grain cleaning+fluid bed drying+secondary drying' assembly line are integrated. The unprocessed grain pretreatment system is suitable for cleaning, drying and stoving of various particle unprocessed grains like rice, wheat and corn, and the impurity content and moisture content indexes of the grains can meet the national regulation restrictiverequirements of being put in storage. The unprocessed grain pretreatment system has the advantages of automation and intelligence and is an essential core system in the modern grain postproduction service center, and the market potentials and promotional value are great.

Description

technical field [0001] The invention relates to the technical field of grain processing equipment, in particular to a raw grain preprocessing system of a grain post-harvest service center. Background technique [0002] my country is a large agricultural country with vast land and abundant resources, and its annual grain output ranks first in the world. Most of the grain sources come from individual farmers. During the grain harvest season, due to the limitation of objective conditions, most of the raw grains have not been cleaned of impurities and dried; the fierce competition in the grain purchase market makes the grain purchase open and free. The way, resulting in raw grain impurity, moisture content and moisture unevenness indicators seriously exceed the standard, which brings a great burden to storage and processing. [0003] Aiming at a series of difficulties for farmers to collect, store, sell, clean and dry grain under the conditions of market-based purchases, it is ...

AI Technical Summary

Problems solved by technology

At present, domestic grain depots and most rice processing enterprises rely on the original process equipment for the cleaning of raw grains. It is difficult to achieve the best of both worlds in terms of cleaning output and quality, and the contradiction between output and quality is becoming increasingly prominent.

A single device is far from meeting the cleaning cycle requirements of large batches; multiple devices work at the same time, the investment increases, the floor area increases, the process route is lengthened, the degree of automation is low, it is not easy to manage and coordinate, and the cost of labor and so on is doubled
