Mass Balance & Waste generation

AI Thread Summary
In the discussion about creating a mass balance for cake production, the focus is on identifying waste generated during the process. Key points include the recognition of egg shells as a waste product, along with other potential losses such as powdered ingredients that may be captured by dust collection systems, spills of oil and water, and broken eggs. It is noted that approximately 1-2% of materials can be lost as waste. Additionally, water is lost as vapor during baking, contributing to the overall mass balance. The discussion also raises questions about whether cakes are completely removed from pans, indicating that some material may remain, further affecting waste calculations. Overall, the conversation highlights the complexities of waste generation in both home and factory settings for cake production.

Hello everyone!

So I'm working on constructing a simple mass balance for a cake. I didn't have any problems doing that, but I was asked about waste that is generated in the process of making the cake. Is there really a waste generated in this kind of process? I've also been asked to discuss how the amounts of waste generation changes when it is being produced in a factory setting.

Here is the materials that I'm using for the cake:

Flour, eggs, oil, water, baking powder and heat

I was thinking that egg shells will be generated as waste. Thats all I came up with.

Please give me some advice if you have any. Thanks.

Coming from the compounding side there is more waste than you would think.

Any powdered material will be sucked into the dust collection system. Oil/water will get spilled, eggs will be broken etc. I think you can safely say 1-2% is lost as waste.

Water will also be evloved in the baking as water vapor.

And is every cake removed completely from the pan?
 
Thanks a lot for the help. I have a better understanding of what to do now. Thank you.
 

Thread 'How could I make it so ferrofluid drops do not coalesce?'

Hello! I've been brainstorming on how to prevent a lot of ferrofluid droplets that are in the same container. This is for an art idea that I have (I absolutely love it when science and art come together) where I want it to look like a murmuration of starlings. Here's a link of what they look like: How could I make this happen? The only way I can think of to achieve the desired effect is to have varying droplet sizes of ferrofluid suspended in a clear viscous liquid. Im hoping for the...

Thread 'How do you fabricate microfluidic chips in your lab?'

Hello everyone! I am curious to learn how laboratories handle in-house chip manufacturing using soft lithography for microfluidics research. In the lab where I worked, only the mask for lithography was made by an external company, whereas the mold and chip fabrication were carried out by us. The process of making PDMS chips required around 30 min–1 h of manual work between prepolymer casting, punching/cutting, and plasma bonding. However, the total time required to make them was around 4...
