Gravity grain cleaning machine and its importance in grain logistics and sustainable agriculture
Abstract
The design schematic of a gravity-based seed cleaning machine was developed, and experimental tests were conducted. The gravity grain cleaning machine (GUTM) demonstrated a cleaning efficiency of 95%, ensuring that seeds met standard requirements in a single cleaning cycle. The compact and lightweight design of the machine, capable of performing the functions of four processing machines, led to a 50-60% reduction in energy consumption and an economic efficiency increase of SUM 1600 thousand/ton. Despite utilizing only one sieve as the primary component, the gravity seed cleaning machine achieved a seed purity level of up to 98.5%, particularly with seed wheat. The device’s implementation resulted in a significant 50-60% reduction in production costs, streamlined inter-district transportation, prevented the mixing of elite seed varieties, and lowered loading and electricity expenses.
