Beverage Heat Exchanger Chilling for Fresh On-Demand Cold Drinks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for creating chilled beverages result in stale products, require advanced preparation, and lead to limited variety options, as they often involve brewing in advance, storage, and dilution issues, failing to provide freshly brewed and customized beverages efficiently.
Innovation Solution
A beverage chiller system comprising a collection section, a heat exchanger section, and a dispensing section, which allows for the rapid chilling of hot beverages to a predetermined temperature, enabling on-demand production of a wide variety of freshly brewed and chilled beverages without dilution, using configurations such as ice baths, double pipe heat exchangers, and thermoelectric devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional methods (refrigerator, freezer, or room temperature storage) are used to chill beverages, then the beverage temperature is reduced, but the beverage becomes stale and develops off flavors due to oxidation and extended storage time
Solution Approach 1:
The system performs preliminary chilling action during the brewing process itself by directing hot beverage through a heat exchanger that pre-cools it before final dispensing. This eliminates the need for separate storage and chilling steps that cause staleness, as the beverage is chilled immediately upon brewing rather than being stored for extended periods.
Solution Approach 2:
The heat exchanger enables rapid chilling of the beverage by forcing hot beverage through a heat exchange medium (ice water or refrigerated fluid) at high speed. This rushes through the chilling process in seconds rather than hours, preventing oxidation and flavor degradation that occur during slow, extended storage chilling.
2Temperature
If regular ice is added to hot beverage to chill it, then the beverage temperature is reduced, but the beverage becomes diluted and loses flavor strength
Solution Approach 1:
The system uses an intermediary heat exchange medium (ice water or refrigerated fluid) to transfer heat from the beverage without direct mixing. This mediator absorbs heat from the hot beverage through the heat exchanger walls, chilling the beverage while preventing any dilution that would occur with direct ice addition.
Solution Approach 2:
The mechanical act of adding physical ice cubes to the beverage is replaced by a thermal field-based heat exchange system. Instead of mechanically introducing solid ice that melts and dilutes, the system uses thermal conduction through a heat exchanger to achieve chilling without substance addition.
3Loss of time
If beverage is brewed in advance and stored for later serving, then storage space is utilized and preparation time is reduced, but the beverage becomes stale and flavor quality deteriorates
Solution Approach 1:
The system rushes through the entire brewing and chilling process in sequence immediately before serving. The heat exchanger enables rapid cooling during dispensing, eliminating the need for advance preparation and storage. Beverages are brewed and chilled on-demand in minutes rather than being prepared hours in advance.
Solution Approach 2:
The system performs preliminary chilling action during the brewing process itself rather than after. The heat exchanger is integrated into the brewing system, so chilling begins immediately as the beverage is being brewed, eliminating the separate storage phase that causes staleness.
4Adaptability or versatility
If multiple types of beverage ice are prepared and stored for different beverage varieties, then beverage variety options are increased, but storage space requirements and labor for production and sorting increase
Solution Approach 1:
The heat exchanger system performs a universal chilling function for all beverage types without requiring separate ice preparations. A single heat exchange medium (ice water or refrigerated fluid) efficiently chills any beverage variety passed through it, eliminating the need for multiple specialized ice storage systems and complex sorting procedures.

AI summary
Exemplary embodiments are generally directed to beverage chillers for chilling a hot beverage so that the hot beverage can be served as a chilled beverage in real time on demand fashion. The beverage chillers include a beverage collection section, a heat exchanger section, and a dispensing section fluidically connected relative to each other. The beverage collection section receives a beverage in a hot state. The heat exchanger section chills the beverage from the hot state to a predetermined chilled temperature. The dispensing section dispenses the beverage at or near the predetermined chilled temperature. Exemplary embodiments are also directed to methods and systems for chilling a hot beverage in real time on demand fashion.
