Food Cereal Roller Device with Dust Suction System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for flaking or crushing edible grain produce dust, leading to processing disturbances and quality impairment.
Innovation Solution
A device with a suction system that captures dust produced during processing, using a vacuum cleaner and adjustable suction nozzles to guide dust upwards and out of the housing, while the grain falls and is discharged at the bottom, preventing condensation and mold formation for hygienic processing. The rollers are motor-driven and adjustable, with scraper plates to prevent buildup and baffle plates to guide grain effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional flaking or crushing rollers are used to process edible grain, then the grain can be processed into flakes or crushed grains, but dust is produced during processing which leads to processing disturbances and quality impairment
Solution Approach 1:
The patent extracts and removes the harmful dust particles from the processing environment using a suction device with suction nozzles positioned near the rollers. The suction device captures dust at its source and removes it through a collection system, separating the harmful dust particles from the processed grain while maintaining continuous processing operation
Solution Approach 2:
The patent introduces air as an intermediary medium to transport dust particles away from the processing zone. The suction device uses air flow to carry dust particles through suction nozzles and into a collection container, creating a controlled air stream that mediates between the dust generation point and the collection point without affecting the grain processing
2Device complexity
If traditional processing without dust removal is used, then the device structure remains simple, but condensation forms leading to mold growth and hygiene problems
Solution Approach 1:
The suction device extracts not only dust particles but also moisture-laden air from the processing environment. By removing the air stream that carries moisture away from the heated rollers, the system prevents condensation on cooler surfaces, thereby eliminating the conditions for mold growth while adding only moderate system complexity
Solution Approach 2:
The patent creates a controlled air environment within the processing chamber by using the suction device to maintain continuous air flow. This controlled atmosphere prevents stagnant moist air from accumulating, effectively creating an environment that is less conducive to condensation and mold formation, similar to maintaining an inert atmosphere to prevent unwanted chemical reactions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables dust-free and hygienic processing of edible grain, allowing for adjustable flake or crush size and reducing the formation of condensation and mold, thereby improving processing quality and hygiene.
Implementation Method 1
a suction device is attached to the housing with the two motor-driven, parallel, mutually parallel and separated from each other by a gap arranged rollers inside the housing by a gap for generating a suction
Implementation Method 2
The negative pressure generated in the housing by the suction device can also prevent the formation of condensation
Implementation Method 3
A throttle valve can expediently be arranged in the intake line. This allows the suction power to be adjusted and the proportion of fine flour in the processed grain to be changed. It can thus also be carried out a wind classification.

AI summary
The invention relates to a device for flaking or grinding food grain, comprising a housing (1), two motor-driven, rotatable rollers (3) arranged parallel to each other and separated from each other within the housing (1) by a gap (2), a feed or metering device (9) arranged on the top of the housing (1) for feeding the food grain to the gap (2) formed between the rollers (3), and a collection and discharge device (13) arranged on the underside of the housing (1) for the food grain deformed between the rollers (3). A suction device (17) is connected to the housing (1) to generate intake air (18) that is drawn in from below via the collection and discharge device (13) and directed along the outside of the rollers (3) to the top of the housing (1).
