10 Steps To Make Your Own Cold Storage At Home

Making cold storage at home is not a new idea and has been around for a long time. People have been making ice boxes out of cold boxes, plant closets and even root cellars. These foods were preserved with just salt water before refrigerators were invented.

Do you know you can convert your simple homeroom into cold storage? Understanding the requirements puts you in a better position to build cold storage on your own or seek professional help if necessary.

Cold storage allows you to store various things ranging from vegetables, fruits, meat, and flowers, among others. Sadly, not each room can be converted into cold storage. Therefore, keep into consideration the following things before choosing the best-suited room:

  • Space availability is crucial, especially when setting up a cold storage room. Therefore, go for the biggest available room as it allows you to store a large number of items when compared to a smaller room.
  • Electricity connection- A cold storage room can’t correctly function if there is limited electricity connection at any given time. As a result, choose a room with a proper electric connection for a cold room.
  • How easy is it to install cooling units in a room? – This is another important thing worth considering before setting up a storage room. A room that is easy to install cooling units gives you an easy time setting up everything. 

Why is a Cold Storage Important?

Some products are easily perishable or sensitive, especially if they stay at room temperatures for a long time. However, cold storage increases the shelf life of products, making them fresh for a long time.

Adjust the right temperature in your cold storage room and store your products there. A cold storage room is different from regular storage mainly because of the cold temperature. Some products stored under room temperatures attract pests and molds. Others might change in texture, color, and even taste.  

Consider cold storage at your home since it prevents food poisoning, common for products stored under room temperature. Cold storage also ensures you enjoy fresh vegetables and fruits for a long time.  

How Does a Cold Storage Operate?

Cooling storage increases the shelf life of products through four main functions, namely:

  • By reducing wilting and internal water loss. Water loss makes products wilt before going bad, especially vegetables and fruits. Therefore, the reduction of water loss increases shelf life.
  • By reducing degradation by enzymes and also respiratory activity. 
  • By inhibiting the growth of decay-producing organisms. These organisms are generally are inactive or slow under cold storage.
  • By reducing the production rate of ethylene, a natural ripening agent. This ensures raw products stay that way for the longest time possible. 

Setting up Cold storage from a simple room

Generally, cold storage allows you to adjust the temperatures, depending on what you are storing. This kick starts by connecting electric circuits to either a window AC or normal split AC units.

Cold storage allows you to adjust the temperatures.

Once connected, the Ac unit can lower the temperatures up to 32 degrees Fahrenheit. Generally, you can have two types of rooms, namely:

  • A storage room with temperatures ranging between 32 to 50 degrees Fahrenheit. Meat, flowers, dairy products, and beer are some products that can be stored under such temperatures.

Converting a Room into a cold room with 32 to 50 degrees Fahrenheit 

Start by plastering all the walls and the floors of the space you intend to convert into cold storage. Afterward, apply preferably thermal coating on the walls. It improves insulation when setting up cold rooms.

Also, the thermal coating helps maintain a temperature between 32 to 50 degrees Fahrenheit while minimizing energy loss. There is also an option of using stainless steel inner walls, but it should be after installing the thermal coating on the room’s walls.

Now, install the Window AC or the Split AC unit after calculating the size of the cold storage room. Each room has a specific number of units and capacity at large. Next, install shelves and anything vital to storing your products once the room is ready.

Setting up a cold room with 53 to 65 degrees Fahrenheit

You can only convert a room to temperatures between 53 to 65 degrees Fahrenheit if it isn’t exposed to extreme temperature levels, specifically the outer walls. Depending on your location, you might not be required to modify the walls of the selected room.

However, consider thermal coating inside the wall to minimize electricity waste and prevent heat loss. A normal plastering might also work, preferably for brick walls. Now, install the AC units in the selected room, depending on the required temperature range and the room’s size.
