Washer Peeler Cleaning System with Movable Spray Bar

Solution Overview

Problem

Traditional vegetable peeling and cleaning apparatuses require manual and time-consuming cleaning of cylindrical rolls, which reduces their effectiveness due to debris accumulation, and safety mechanisms prevent rolls from rotating during conventional cleaning processes.

Innovation Solution

A cleaning system featuring a spray bar with nozzles that can move along the length of the rolls, driven by a prime mover, allowing for the simultaneous spraying of liquid onto the rolls and their rotation, ensuring thorough and efficient cleaning while maintaining safety compliance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual cleaning of rolls is performed by opening the cover, then the rolls can be accessed for cleaning, but the cleaning process becomes time-consuming and safety mechanisms prevent rolls from rotating during cleaning

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system enables the rolls to clean themselves by rotating in place while the spray bar applies cleaning solution and uses high-velocity air streams to blow debris off the rolls, eliminating the need for manual disassembly and cleaning operations

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical cleaning process is replaced with an automated system that uses fluid dynamics (spray bars, high-velocity air streams) and the rolls' own rotation to achieve cleaning, eliminating the need for operator intervention and manual labor

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If the machine cover is opened for cleaning, then the rolls are accessible, but safety mechanisms prevent the rolls from rotating during the cleaning process

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The rolls perform their own cleaning by rotating and allowing the spray bar to apply cleaning agents and air streams to their surfaces, maintaining safety compliance while achieving thorough cleaning without manual intervention

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Instead of stopping the rolls to clean them, the system reverses the approach by cleaning the rolls while they are rotating, using the rolls' own motion to facilitate the cleaning process rather than hindering it

Inventive Principle:
Principle #13The other way round (Inversion)

3Device complexity

If a stationary spray bar is used, then the structure is simple, but it cannot clean all surfaces of the rolls effectively

Engineering Contradiction:
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The spray bar is transformed from a stationary component to a movable one that travels along the rolls, enabling it to reach and clean all surfaces of the rolls including end surfaces, while maintaining relatively simple structural implementation through linear movement

Inventive Principle:
Principle #15Dynamics

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

The system enables complete and consistent cleaning of the rolls and surrounding surfaces, reducing manual effort and variability, ensuring efficient operation and compliance with safety regulations by cleaning the rolls while they rotate and the machine doors are closed.

Implementation Method 1

The spray bar has at least one nozzle directed toward the rolls that is configured for spraying liquid toward at least one of the working surfaces of the rolls

Methodology Applied
Scientific EffectFluid spray: Fluid Spray

AI summary

An apparatus for cleaning a food-processing machine having cylindrical rolls disposed along a curve, each of the rolls having a peripheral working surface for contacting food products and an axis about which each roll rotates. A drive rail is mounted parallel to the axes of the rolls and extends the length of the rolls. A spray bar slidably mounts to the drive rail, extends adjacent the rolls, and has at least one nozzle for spraying liquid onto the working surfaces of the rolls to clean them of debris. A prime mover drives the spray bar along the drive rail parallel to the axes of the rolls while spraying the rotating rolls.
