Method for preparing a very hot beverage in a container from a beverage dispensing device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hot water beverage dispensing machines fail to maintain water temperatures above 80°C during the preparation of very hot drinks, leading to inefficient infusion of ingredients and potential splashing, which can result in burns or contamination.
Innovation Solution
The method involves injecting steam directly into the container to maintain water temperatures above 80°C, accompanied by agitation using a rotary stirring device to break bubbles and prevent splashing, allowing for efficient infusion without a heating base and reducing preparation time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If hot water is poured into a container to prepare a beverage, then the beverage preparation process is initiated, but the water temperature drops quickly and becomes insufficient for proper infusion
Solution Approach 1:
The system pre-heats the container base before pouring hot water into it. This preliminary heating action ensures that the container is already at an elevated temperature, reducing the thermal loss when hot water is added and maintaining the water temperature above 80°C for proper infusion.
Solution Approach 2:
A heating base acts as an intermediary element between the hot water and the container. The heating base receives hot water or steam from the dispensing system and transfers heat to the container through thermal conduction, maintaining the required temperature without directly heating the beverage.
2Temperature
If a heating base is added to maintain water temperature during brewing, then the water temperature is maintained, but the device complexity increases
Solution Approach 1:
The heating base is designed to serve multiple functions: it heats the container before brewing, maintains water temperature during infusion, and can be integrated with the existing dispensing system. This multi-functionality reduces the need for separate heating devices and minimizes overall system complexity.
Solution Approach 2:
The heating base is merged with the container or integrated into the dispensing machine structure. By combining the heating function with the existing container or machine components, the patent avoids adding a completely separate heating system, thereby reducing device complexity while maintaining temperature control.
3Temperature
If very hot water is poured into a container, then the beverage preparation is started, but bubbles form and cause splashing that can burn or contaminate the surface
Solution Approach 1:
The system applies preliminary anti-action by pre-heating the container base before adding hot water. This pre-heating reduces the thermal shock that causes rapid bubble formation and splashing. Additionally, the controlled pouring method and potential anti-splash structures prevent harmful splashing before it occurs.
4Productivity
If the ingredient is infused in hot water that cools down quickly, then the infusion process is simpler, but the full aroma and flavor are not extracted
Solution Approach 1:
The container base is pre-heated before adding the ingredient and hot water. This preliminary heating ensures that the infusion environment is already at the optimal temperature, allowing the ingredient to immediately begin extracting full aroma and flavor without waiting for the water to maintain temperature.
Solution Approach 2:
The heating base continuously maintains the water temperature above 80°C throughout the entire infusion process. This continuous heating action ensures that the water remains at the optimal temperature for extraction, allowing the infusion to proceed efficiently and extract the full aroma and flavor of the ingredient.

AI summary
The invention relates to a method for preparing a very hot beverage in a container (4) using a beverage dispensing machine (1) comprising a control circuit, a hot water and/or steam generator, and a rotary stirring device (6) including a tool rotating about an axis A and intended to interact with a beverage contained in the container. The rotary stirring device includes a conduit for supplying hot water and/or steam to the rotary tool.The process includes the following steps: a) placing the container on a support (3), under the rotary stirring device and then placing the rotary tool in said container; b) selecting and starting a very hot water preparation from the control circuit; c) injecting a volume V of hot water through the delivery line; d) injecting steam through the delivery line to bring the water to a temperature above 80°C; d1) during step d), starting the rotary tool to stir the preparation and break the bubbles that form in the preparation under the action of the steam and thus prevent splashing outside the container.
