Solution Overview

Problem

Current methods and machines for producing liquid or semi-liquid food products, such as ice cream, face challenges in achieving high-quality, rapid, and repeatable production while maintaining simplicity and effectiveness.

Innovation Solution

A machine comprising a first processing container with a cooling cylinder, a rotary stirrer, and a thermal treatment system, along with a connecting duct and control unit, allows for the recirculation and uniform processing of the product, enabling efficient transfer and dispensing of high-quality ice cream products by controlling the flow between containers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single container is used for processing and dispensing, then the device complexity is reduced, but the productivity decreases due to waiting times for freezing and processing

Engineering Contradiction:
Improveproduction speedVSAvoidmachine structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The machine is divided into two independent processing containers (first container 2 and second container 21), each capable of simultaneous operation. The first container processes basic liquid products while the second container freezes and stores the processed product, allowing continuous production without waiting for freezing cycles.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first container performs preliminary processing of the basic liquid product (mixing, homogenization) before transfer to the second container for freezing. This preliminary action allows the freezing process to begin earlier and in parallel with ongoing processing, reducing overall production time.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If product transfer between containers is continuous, then the productivity increases, but the manufacturing precision decreases due to potential quality variations

Engineering Contradiction:
Improveproduction continuityVSAvoidproduct quality consistency
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The control unit 60 replicates the optimal processing parameters and sequence in both containers, ensuring that each container operates with identical settings for mixing, thermal treatment, and processing duration. This copying of parameters guarantees consistent product quality across continuous production cycles.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

Sensors monitor temperature, mixing speed, and processing parameters in real-time in both containers, with the control unit continuously adjusting operations to maintain precise quality standards during continuous transfer and processing.

Inventive Principle:
Principle #23Feedback
