Water cooled draft beer machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional draft beer machines have a slow refrigeration speed, resulting in a poor refrigeration effect for beer due to the limited cooling capacity of the water tank.
Innovation Solution
A water cooled draft beer machine with a refrigeration circuit, coiled refrigeration tubes in the water tank, a cold storage chamber, and a circulation mechanism using a stirring motor and fan to enhance cooling efficiency by pre-cooling the beer and utilizing the full cooling capacity of the cold water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the beer pipe is located inside the water tank for refrigeration, then the beer can be cooled, but the refrigeration speed is slow and the refrigeration effect is poor
Solution Approach 1:
The refrigeration system is divided into two independent parts: a cold storage chamber that pre-cools the beer in the cask, and a water tank that further cools the beer during dispensing. This segmentation allows each part to perform its cooling function independently and simultaneously, greatly improving the overall refrigeration speed and effect.
Solution Approach 2:
The cold storage chamber performs preliminary cooling of the beer in the cask before the beer enters the dispensing pipeline. This preliminary action ensures that the beer is already cooled to a lower temperature before it reaches the water tank, reducing the cooling burden on the water tank and accelerating the overall refrigeration process.
2Temperature
If the water tank cools the beer directly, then the beer can be refrigerated, but the cooling capacity of the water tank is not fully utilized
Solution Approach 1:
The cold storage chamber performs preliminary cooling of the beer before it enters the water tank. This ensures that the water tank receives pre-cooled beer, reducing the cooling burden and allowing the water tank to operate more efficiently within its optimal cooling capacity range.
Solution Approach 2:
The cold storage chamber acts as an intermediary cooling stage between the beer cask and the water tank. It prepares the beer by removing a portion of the heat load before the beer enters the water tank, allowing the water tank to focus its cooling capacity on the remaining temperature reduction.
