Dosing Machine for Pasty Products with Compression Auger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual production of Molase doses results in variable weights and densities due to the elastic nature of tobacco, leading to inconsistent final product when mechanized, as existing machines fail to ensure uniformity in dosage both in volume and weight.
Innovation Solution
A dosing machine with a hopper and auger system that fills dosage chambers independently, using flow adjustment and position sensors to ensure each chamber is fully filled before dispensing, and compressed-air pistons to compact the material uniformly, guaranteeing identical doses in weight and volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual production is used to form Molase doses, then flexibility and ease of operation are maintained, but manufacturing precision and consistency of dose weight are poor
Solution Approach 1:
The patent replaces manual mechanical operations with an automated dosing machine that uses a hopper, auger, and dosage chamber system. The machine automatically measures, compacts, and forms doses with consistent weight and volume, eliminating the variability inherent in manual production while maintaining operational simplicity through automated control.
Solution Approach 2:
The patent controls critical parameters including chamber volume, material density, and compaction pressure to ensure consistent dose weight. By maintaining constant chamber dimensions and applying uniform compaction force, the system achieves precise dosage control regardless of material elasticity variations.
2Productivity
If existing mechanized dosing machines are used with a single hopper and auger system, then productivity is improved, but manufacturing precision deteriorates due to variable material density at different mixing points
Solution Approach 1:
The patent divides the single hopper-auger system into multiple independent dosing chambers, each receiving material from the same source but dosing separately. This segmentation ensures that each chamber receives relatively uniform material and can be precisely controlled, maintaining both high productivity through parallel operation and high precision through individual chamber control.
Solution Approach 2:
The patent incorporates sensors that detect when each dosage chamber is fully filled before the dosing cycle begins. This feedback mechanism ensures that no chamber starts dosing until properly filled, preventing under-dosing or over-dosing and ensuring weight uniformity across all doses produced in parallel.
3Shape
If doses are cut to uniform length after extrusion, then shape consistency is improved, but weight consistency deteriorates due to variable material density
Solution Approach 1:
The patent performs compaction and volume standardization before the dosing and cutting operations. By pre-compacting the material in the dosage chamber to a precise volume and density, the subsequent cutting operation produces doses with both uniform shape and uniform weight, as the material is already in its final dense state before sectioning.

Function Achieved in This Case
The machine enables mechanized production of Molase doses with consistent weight and volume, ensuring each dose is identical and accurately formed, addressing the variability issues in manual production.
Implementation Method 1
