Modular Granulator Housing for Rapid Product Changeovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing granulators require extensive disassembly and cleaning for product changes, leading to long downtimes and risk of contamination due to cutting residues during the process.
Innovation Solution
The cutting device and conveying device are configured as a modular unit with a separate module housing that can be detached from the granulator housing for cleaning, allowing for quick product changes without environmental contamination, with a releasable coupling ensuring efficient force transmission and easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the granulator is fully disassembled for cleaning during product change, then complete cleaning is achieved, but downtime increases significantly
Solution Approach 1:
The granulator is divided into a stationary granulator housing and a detachable module housing containing the cutting device and conveying device. This segmentation allows the module housing to be removed as a complete unit for cleaning, achieving thorough cleaning without requiring disassembly of the entire granulator, thus reducing downtime while maintaining cleaning completeness
Solution Approach 2:
The cutting device and conveying device are extracted from the main granulator housing and placed into a separate module housing that can be detached. This extraction enables the module housing to be removed and cleaned externally, ensuring complete cleaning of all material-contact surfaces without prolonged停机 of the granulator
2Reliability
If the cutting device is disassembled for cleaning, then complete cleaning is achieved, but contamination risk increases due to loose parts
Solution Approach 1:
By segmenting the cutting device and conveying device into a dedicated module housing, the design ensures that all cleaning-related disassembly occurs within the contained module rather than involving loose parts in the main housing. The module housing acts as a self-contained unit that prevents cutting residues from contaminating the environment during cleaning operations
Solution Approach 2:
The cutting device and conveying device are extracted into a separate module housing that can be removed as a complete unit. This extraction eliminates the risk of loose cutting parts and residues contaminating the granulator housing or environment during cleaning, as the entire module can be cleaned externally in a controlled manner
3Reliability
If extensive disassembly is performed for product change, then complete cleaning is achieved, but installation effort and cost increase
Solution Approach 1:
The granulator is segmented into a stationary housing and a detachable module housing containing all moving parts (cutting device and conveying device). This segmentation standardizes the cleaning and replacement process, reducing installation effort compared to extensive disassembly while ensuring complete cleaning of all material-contact surfaces
Solution Approach 2:
The cutting device and conveying device are merged into a single integrated module housing that moves as one unit. This merging simplifies the cleaning and replacement process by treating both devices as a single replaceable unit, significantly reducing installation effort and cost compared to disassembling and handling multiple separate components

AI summary
The invention relates to a granulator having a cutting device which is driven by a drive device and to which a material strand can be supplied, for example by means of a conveying device. The drive device is accommodated in a granulator housing. The cutting device and optionally also the conveying device are arranged in a separate module housing, which is connected in a detachable manner to the granulator housing and can be removed from same. The cutting device and/or the conveying device are connected to the respective drive device via detachable couplings. The cutting device and optionally also the conveying device can be removed from the granulator housing as a unit together with the module housing.
