Ice Cream Machine with Gear Pump for Simultaneous High and Low Overrun Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The ice cream industry requires a compact machine capable of simultaneously producing ice cream-type products with increased volume and products with consistent volume, such as fruit-based products or yogurts, which existing machines fail to address effectively.
Innovation Solution
A machine with multiple containers and thermal treatment systems, including a gear pump for mixing and compressing liquid or semi-liquid products with air, and a suction device for mixing with air, allowing for the production of products with high and low overrun simultaneously, enabling the creation of both high-overrun ice cream and low-overrun yogurt-type products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single machine is used to produce both ice cream-type products (high overrun) and yogurt-type products (low overrun), then space and costs are optimized, but the device complexity increases
Solution Approach 1:
The machine is divided into two independent processing circuits: a first circuit with a first container and first stirrer for high-overrun ice cream products, and a second circuit with a third container and fourth stirrer for low-overrun yogurt products. Each circuit has its own thermal treatment means and dispensing device, allowing simultaneous production of different product types while maintaining operational simplicity through modular independence.
Solution Approach 2:
The machine incorporates multiple containers (first, second, third, fourth containers) that can simultaneously hold and process different basic products. The system includes both a gear pump for high-overrun products and a suction device for low-overrun products, enabling a single machine to perform multiple functions that would traditionally require separate equipment.
2Quantity of substance
If a gear pump is used to mix and compress liquid product with air for high overrun, then product volume increases, but the device complexity increases
Solution Approach 1:
The gear pump combines multiple functions into a single device: it transfers the liquid basic product from the first container to the second container, compresses the product, and mixes it with air simultaneously. This integrated approach achieves high overrun (increased product volume) without requiring separate mixing equipment, thereby reducing overall system complexity.
3Manufacturing precision
If thermal treatment means are applied to control product temperature during processing, then product quality is improved, but energy consumption increases
Solution Approach 1:
The thermal treatment means are applied to the containers before the actual product processing begins. The first, second, third, and fourth containers are pre-cooled or heated to the required temperatures, allowing the product to maintain proper temperature throughout processing without requiring continuous energy input during mixing and dispensing operations.
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 machine efficiently produces two different types of products with varying overrun levels simultaneously, optimizing space and reducing costs, while ensuring precise temperature control and mixing processes.
Implementation Method 1
