Kitchen Waste Comminution and Dewatering Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The collection and disposal of kitchen waste pose challenges due to vermin attraction, odor issues, and health hazards, as existing methods require frequent collection and lack effective on-site processing solutions for domestic and commercial kitchens.
Innovation Solution
An apparatus that processes kitchen waste into a stable, dry, and rot-resistant granular form by comminuting, dewatering, compressing, and mixing with a cementitious powder to inhibit bacterial growth, allowing for on-site treatment and reduced collection frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If kitchen waste is stored for collection, then collection frequency can be reduced, but vermin attraction and odor problems worsen
Solution Approach 1:
The apparatus performs preliminary processing of kitchen waste by comminuting, dewatering, compressing, and mixing with cementitious powder before final disposal. This preliminary action stabilizes the waste, preventing vermin attraction and odor generation, thereby allowing for reduced collection frequency while eliminating the harmful effects associated with stored waste.
Solution Approach 2:
The apparatus changes the physical and chemical parameters of kitchen waste through comminution (reducing particle size), dewatering (removing moisture), compression (increasing density), and mixing with cementitious powder (altering chemical composition). These parameter changes transform the waste into a stable, non-attractive form that does not generate odors or attract vermin.
2Object-affected harmful factors
If on-site processing is implemented, then vermin attraction and odor issues are reduced, but device complexity increases
Solution Approach 1:
The processing apparatus is segmented into distinct functional modules: comminution device, dewatering device, compression device, and mixing device. Each module performs a specific function in the waste treatment process, making the overall system more manageable and easier to implement while effectively reducing vermin attraction and odor problems through comprehensive processing.
3Stability of the object's composition
If waste is processed into granular form, then storage stability improves, but processing time and energy consumption increase
Solution Approach 1:
The apparatus applies parameter changes through controlled compression and mixing with cementitious powder to transform waste into stable granular form. The compression process densifies the waste while the cementitious powder chemically stabilizes it, creating a product that maintains its composition during storage. This approach achieves stability while managing energy consumption through efficient processing parameters.
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 apparatus produces a stable, odor-free, and pest-resistant waste product that can be stored for extended periods without refrigeration, reducing collection frequency and addressing health and vermin-related issues.
Implementation Method 1

AI summary
A method of processing waste, such as food waste, from a kitchen is described in which apparatus on the premises of the kitchen receives the waste, comminutes the received waste to provide comminuted waste, dewaters the comminuted waste to provide dewatered waste, compresses the dewatered waste to produce compressed waste; and provides processed waste to await collection.
