Evolution of Food Storage from Ice Men to Freezers
Read moreIce cream is an all-time favorite dessert for all. After a tasty lip-smacking dinner or lunch, everyone’s favorite is a sweet, creamy ice-cream to make the meal complete. Today, visiting an ice-cream parlor for this delicious dessert is very common, but have you ever thought about ice-cream when there was no freezer?
The no-freezer era
Yes, before the invention of a freezer in the 19th and 20th century, people used a traditional method for refrigeration. An iceman collected snow in winters, salted and wrapped it in a flannel and preserved it underground for months. He then delivered this ice across the whole country as per requirements for a price.
The household refrigeration method was quite different. People used a wooden box that was lined with an insulating material like zinc and filled with snow and ice. This was known as an “ice-box.” This method of refrigeration was not very efficient and hardly lasted for a week.
Invention of the freezer
Development of the freezer was started by a Scottish doctor in the 18th century. Later, many scientists and engineers contributed to the invention and advancement of the refrigerator. The procedure started in the 1740s when William Cullen came up with a new demonstration by evaporating ethyl Ether in vacuum.
Later in the 1800s, Oliver Evans, an American scientist designed the first refrigerator, but the design was of no use then. In the 1820s, Michel Faraday started using liquefied ammonia for cooling processes. Later in 1835, Jacob Perkins built the first refrigerator, and is hence known as the “father of the refrigerator.”
In the year 1842, John Gorrie used Oliver’s design to invent the advanced refrigerator that created ice. Many scientists contributed toward the advancement of the refrigerator. Some of these were Ferdinand Carre, Carl von Linde, Albert T. Marshall, and Albert Einstein.
Finally, in the year 1913, Fred W. Wolf came up with the first ever commercial upright freezers. By the end of the 19th century, this refrigerator became famous and became common in breweries. Nearly every brewery owned a commercial upright freezer for the storage and cooling of beers.
How do commercial upright freezers work?
The refrigerants present in the refrigerator pass through the tubes. Here, this refrigerant gets vaporized and during evaporation and carry away the heat. This heat is released outside the refrigerator passing through the coils. The gases move back to the compressor where it is again converted into a liquid. This continuous process allows the constant cooling.
Modern commercial upright freezer
Earlier, the cooling elements used in the refrigerator were not safe. It was in 1926 when an American engineer came up with a gas called chlorofluorocarbons. However, by the 1970s, the researchers proved that the chlorofluorocarbons were not environmentally friendly. Hence, present-generation commercial upright freezers contain hydrofluorocarbons. Although being safer than CFCs, HFCs also lack environmental friendliness.

3 essential things to know about influenza type B virus
Read moreCaused by flu viruses, influenza is an infection of the respiratory system. There are three types of influenza virusesA, B, and C. Each has different levels of severity and the treatment too varies accordingly. The symptoms and severity of influenza type A and B are nearly similar, while influenza type C is fairly mild. Read on to know more about what is the influenza type B virus, its causes, symptoms, and risk factors.
Causes of influenza type B
Flu caused by influenza type B virus is highly contagious and spreads from person to person. This is why flu outbreaks are commonly observed during a particular season, especially during winter. The flu spreads through droplets from a sneeze or cough of the person who is infected by the virus. In certain cases, the virus can spread by breathing in aerosols, which are small air particles. These particles have been known to travel nearly six feet after they have been exhaled by an infected person.Symptoms of influenza type B
Influenza type B virus affects the respiratory as well as the digestive system. Some of the common symptoms include fever, chills, sore throat, coughing, runny nose, sneezing, fatigue, muscle aches, and body pain. The symptoms are often similar to a common cold. On the onset of flu, the respiratory system experiences congestion. A person will also experience a sore throat just before the flu hits them completely. There may be fever as high as 106F. Furthermore, a person with influenza type B flu may also experience chills, abdominal pain, nausea, vomiting, loss of appetite, and weakness.
People with asthma need to be extremely careful and seek treatments as soon as possible. This is because influenza type B virus triggers asthma attacks and the symptoms become very severe. If flu caused by this virus is not treated on time, it may lead to many health complications such as sepsis, heart inflammation, kidney failure, respiratory failure, bronchitis, and pneumonia.Risk factors
There are specific groups of people who may have a higher susceptibility to flu caused by influenza type B virus. Children between the ages of 2 years and 5 years have a high risk of contracting this flu. Similarly, adults who are older than 65 years are at a high risk. Residents of long-term care facilities and nursing homes are also susceptible to influenza flu due to the lack of fresh air and staying in air-conditioned rooms for long hours. Other risk factors include a weak immune system, obesity, and chronic illnesses such as diabetes, heart disease, asthma, liver disease, and kidney disease. Pregnant women and women who are two weeks into postpartum are also highly susceptible to influenza type B virus.
