Cooking Chamber Floor Preheating to Prevent Hot Milk Scorching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In commercial kitchens, preparing hot milk is challenging due to the risk of burning, as existing solutions like milk boilers are not suitable for canteen kitchens and automatic stirrers are unreliable, leading to soiling and increased cleaning efforts.
Innovation Solution
A method involving uniform heating of the cooking chamber floor to above 100°C, followed by a small amount of water evaporation to cool the surface, then pouring in milk to prevent scorching, utilizing the stored heat energy for even heating and mixing, ensuring the surface temperature remains below 100°C to prevent burning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cooking chamber floor is heated to high temperatures (above 100°C) to efficiently heat milk, then heating efficiency is improved, but the risk of milk burning increases
Solution Approach 1:
The cooking chamber floor is preheated to a controlled temperature range (80-100°C) before milk is added. This preliminary heating action prepares the surface to be warm enough for efficient heat transfer but not so hot as to cause immediate burning, resolving the contradiction between heating efficiency and burning risk
Solution Approach 2:
The method controls and maintains the cooking chamber floor temperature within a specific parameter range (80-100°C) rather than using higher temperatures. By changing the temperature parameter to this optimal range, the system achieves sufficient heating efficiency while preventing the harmful effect of milk burning
2Object-affected harmful factors
If the milk is heated slowly and gently to prevent burning, then the risk of milk burning is reduced, but the preparation time increases
Solution Approach 1:
The cooking chamber floor is preheated before milk addition, creating a warm surface that facilitates immediate and efficient heat transfer to the milk. This preliminary action eliminates the need for slow, gradual heating, allowing fast heating without burning risk
Solution Approach 2:
The method enables the system to skip the slow heating phase by utilizing the preheated surface. The milk is rapidly heated from the start because the cooking chamber floor is already at the optimal temperature, thus rushing through the heating process without causing burning
3Object-affected harmful factors
If a separate water chamber is added to prevent direct contact between milk and hot surfaces, then milk burning is prevented, but the device complexity increases
Solution Approach 1:
The invention extracts and eliminates the need for a separate water chamber by directly controlling the temperature of the cooking chamber floor. Instead of adding a complex intermediate water layer system, the solution removes the burning risk through temperature control of the existing heating surface
Solution Approach 2:
The cooking chamber floor serves multiple functions: it provides structural support, enables efficient heat transfer to milk, and prevents burning through controlled temperature maintenance. This multi-functionality eliminates the need for separate protective chambers while achieving burning prevention
4Adaptability or versatility
If the cooking chamber floor is used for high-temperature cooking applications, then versatility is improved, but the risk of milk burning increases
Solution Approach 1:
The system dynamically adjusts the temperature of the cooking chamber floor based on the cooking application. For milk heating, the temperature is controlled at 80-100°C to prevent burning, while for other high-temperature applications, the temperature can be increased. This dynamic temperature control enables versatility without compromising milk safety
Solution Approach 2:
The temperature parameter of the cooking chamber floor is changed and optimized specifically for milk heating applications (80-100°C), while maintaining the capability to operate at higher temperatures for other cooking tasks. This parameter optimization resolves the contradiction between versatility and burning prevention

AI summary
The method involves preheating the cooking chamber by the heatable cooking chamber floor (11). A small quantity of water (W) in comparison to the quantity of milk (M) to be prepared is filled in the preheated cooking chamber, such that the water is evaporated. The milk to be prepared is subsequently filled before the water previously filled is completely evaporated and the milk is heated to the desired temperature. An independent claim is included for a cooking device for preparing hot milk.
