On a hot summer day in our town, an ice cream meltdown that lasted nearly three hours caused chaos in the streets. The main cause of the meltdown was a pipe failure at an ice cream factory outside of town. This malfunction resulted in a surge of cold liquid nitrogen that increased the pressure within the pipes to dangerous levels, causing them to burst and releasing large amounts of highly-concentrated melted ice cream along city blocks.
The effects of this meltdown were far-reaching and devastating. Not only did it create an unsightly mess on the sidewalks, but it also put pedestrians at risk as they maneuvered around slippery surfaces. Additionally, many business owners had to close up shop for fear that the melt will damage their property or contaminate any food products. Finally, emergency services such as fire brigades and hazardous material teams had to be dispatched to contain and clean up the mess – leading to massive disruptions throughout the area.
Overall, this ice cream meltdown serves as a reminder of why proper maintenance and inspections are so important. With more oversight, these types of disasters can be avoided before they even happen – sparing our town from costly damages and potential injury risks.
Science Behind the Meltdown
Many factors can influence the melting of ice-cream. These include the temperature, composition, fat, aeration level and stabilizer/emulsifier system.
The melting property of fat is affected by the size of fat globules. In homogenized ice cream, the size of fat globules was significantly larger than in non-homogenized ice cream. The key to ice cream’s stability is the partial coalescence of fat globules around air cells.
The homogenization process also affected the amount of aeration. A higher aeration level contributed to faster melting. Likewise, a lower level of aeration did not significantly affect the melting rate.
A stable ice cream can be made with homogenization pressures at least 10 MPa. It is not necessary to perform double-stage homogenization if the fat content is less than 10%.
Another factor that contributes to a high consistency coefficient is fiber addition. Fiber addition increases viscosity. Besides, fiber also positively impacts the texture of the ice cream.
