多仓自适应家用智能杂粮桶设计
Design of a Multi-Chamber Adaptive Smart Coarse Cereal Storage Container for Household Use

针对家庭多品类杂粮储存中易受潮霉变、串味混杂、取粮计量不便等问题，设计了一种多仓自适应家用智能杂粮桶。整机采用四仓独立密封结构，每仓配置温湿度传感器与对开门式干燥剂舱：仓内湿度超标时舱门自动开启，食品级硅胶干燥剂经自然扩散吸附水汽，湿度回落至适宜区间后舱门自动关闭，构成低功耗闭环动态除湿。顶部集成扫码识别模块，扫描杂粮包装溯源码即可自动匹配该品类适宜的存储湿度区间，实现分仓差异化保鲜。取粮时通过触控屏设定质量，步进电机驱动料斗式下料轮下料，称重传感器实时反馈并在达到设定值时自动停机。完成了整机结构与控制系统设计，对干燥剂用量、下料计量精度与整机功耗进行了理论核算，并给出结构强度仿真与控湿性能台架试验方案。该设计不依赖真空、充氮等高能耗部件，成本与运行功耗低，为家庭小型储粮装备提供了一种可行的技术方案。
Aiming at the problems of moisture absorption, mildew, odor mixing and inaccurate manual metering in household storage of multiple coarse cereals, a multi-chamber adaptive smart coarse cereal storage container for household use is designed. The device adopts a four-chamber independently sealed structure, and each chamber is equipped with a temperature-humidity sensor and a double-door desiccant compartment: when the chamber humidity exceeds the upper limit, the compartment door opens automatically, and the food-grade silica gel desiccant adsorbs moisture through natural diffusion; when the humidity falls back to the appropriate range, the door closes automatically, forming a low-power-consumption closed-loop dynamic dehumidification system. A code-scanning module is integrated on the top cover; by scanning the traceability code on the cereal package, the device automatically matches the suitable storage humidity range for the corresponding category, realizing differentiated fresh-keeping among chambers. For grain dispensing, the user sets the target mass on the touch screen, a stepping motor drives the hopper-type discharge wheel, and the weighing sensor provides real-time feedback so that the motor stops automatically when the set value is reached. The overall mechanical structure and control system are designed; the desiccant dosage, dispensing accuracy and power consumption are theoretically analyzed; and structural strength simulation together with bench test schemes for humidity-control performance is presented. The design requires no high-energy-consumption components such as vacuum or nitrogen-filling devices, features low purchase and operating costs, and provides a feasible technical solution for household small-scale grain storage equipment.
