Rice Rotary Vibrating Cleaner

Rice Rotary Vibrating Cleaner - Foundational Pre-Cleaning for Milling

Ensuring Purity from Harvest to Processing
The Rice Rotary Vibrating Cleaner is typically the very first machine in the rice mill processing line. Its primary function is to perform the initial cleaning of raw paddy rice received from the farm or storage, removing large, medium, and fine impurities to protect downstream equipment and ensure processing efficiency. Shijiazhuang Xinlu Technology Co., Ltd. provides robust solutions for this critical pre-processing stage.

Combined Cleaning Principles: This machine integrates multiple cleaning actions within a single unit:

1. Screening: Utilizes multiple layers of screens (sieves) with progressively smaller apertures. The top screen removes large impurities (straw, stalks, clods, stones larger than grain). The middle screen separates the paddy from larger impurities and potentially smaller grains or seeds. The bottom screen allows good paddy to pass while removing small impurities (sand, soil, small seeds, broken grains).

2. Vibration: The entire screen assembly is mounted on springs and subjected to controlled vibration (often via eccentric weights on a rotating shaft). This vibration fluidizes the material bed, ensuring grains make contact with the screen apertures and move efficiently across the deck for stratification and separation. It also prevents screen blinding.

3. Aspiration (Air Current): A powerful fan generates an adjustable air current that passes through the falling stream of material, typically after the screening stages. This removes light impurities like dust, husk fragments, empty grains, and light chaff based on differences in aerodynamic properties (terminal velocity). The air velocity is critical – too low leaves impurities, too high removes good grain.

Design & Functional Components: Multi-Deck Screen Box: Houses the interchangeable screens with specific aperture sizes tailored to the paddy variety and common impurities. Eccentric Drive Mechanism: Provides the necessary vibration frequency and amplitude. Vibration Isolation Springs: Minimize transmission of vibration to the mill structure. Centrifugal Fan & Air Duct: Generates and directs the cleaning air stream. Aspiration Chamber: Where the air effectively separates light impurities from the heavier grain. Dust Collection Outlets: For removing collected light impurities. Feed Distributor: Ensures even material distribution across the width of the top screen. Discharge Outlets: Separate outlets for cleaned paddy, large impurities, small impurities, and aspirated light waste.

Operational Importance: Effective pre-cleaning is non-negotiable. Removing stones and metal protects expensive huskers, hullers, and whiteners from catastrophic damage. Eliminating dust and chaff improves the working environment, reduces explosion risks, and prevents clogging in downstream equipment like elevators and silos. Removing sand and soil minimizes wear on machinery components and prevents contamination of the final rice product. Removing oversized and undersized materials ensures consistent flow and processing efficiency in subsequent stages.

Optimization & Maintenance: Screen Selection: Choosing the correct aperture sizes for the specific paddy and impurity profile is essential. Vibration Adjustment: Amplitude and frequency settings influence material flow speed and separation efficiency. Air Volume Adjustment: Must be calibrated to effectively remove light impurities without excessive good grain loss. Regular Checks: Screens must be inspected for wear, tears, or clogging and cleaned/replaced as needed. Dust collection points must be kept clear. Drive belts, bearings, and springs require periodic inspection and lubrication.
