How long can we refrigerate foods safely
Have you ever wondered how long can we store our foods in our refrigerator so that it is still safe to eat? Apparently the USDA (United States Department of Agriculture) think this is important and have published some useful recommendations on how to refrigerate our food safety. Refrigeration Basics Keeping foods chilled at proper temperatures […]
Coldroom Temperature Controllers
Every coldroom system must have at least 1 temperature controller. A temperature controller consists of a temperature sensor and an electric on-off switch. When the interior temperature is too high, the coldroom temperature controller will send a signal to the compressor to turn on, activating the refrigeration cycle. Conversely, once the desired temperature has been […]
Coldroom Compressors and Condensers
The most important components of a coldroom must be the compressor and the condenser. You can compare the compressor to the human heart and the condenser as the lungs. CompressorThe role of a compressor in a coldroom system is to pressurize the refrigerant fluid. Acting like a pump, the refrigerant under pressure will heat up […]
Walk in Coldrooms. A Short Introduction
Generally there are three kinds of cold rooms: self-contained, remote condensing, and multiplex condensing. Self-contained coldrooms are cold storage rooms where the refrigeration system is a complete package with the evaporator and condenser built into one unit. The obvious advantage of self contained coldrooms is they are simple to install and can be moved easily […]
What are the Best Temperatures to store Wines
If you own a wine chiller, you may wonder what are the best temperature settings to store your wines in perfect condition. The trick with wine is to store it at a stable, ideal temperature, and then to serve it at a temperature which best shows off its personal characteristics. If you serve a wine […]
How Refrigeration Works?
Ever wondered how that commercial refrigerator of yours keeps humming and keeps your precious foods cold? This humble piece of equipment is probably one of mankind’s best inventions! Refrigeration technology is key to preserving our foods and made feeding mankind feasible in a large scale. Starting within the enclosed space of a refrigerator or a […]
What are Refrigerants?
A refrigerant is a substance used to transfer heat from one area and move it to another area. By pumping it around an enclosed space, the refrigerant is able to cool an area by moving heat away. They are usually made from organic compounds with low boiling points like fluorocarbons, chlorofluorocarbons (CFC’s) and hydrocarbons. Refrigerants […]
Blast Chiller & Blast Freezers Singapore
What is Blast Chilling and Freezing? Blast chilling and blast freezing is a method of cooling foods and quickly to prevent the spread of bacteria. Harmful bacteria multiply between +8 °C to +68 °C. The idea is by reducing the temperature of foods to +3°C or below within 90 minutes, food is rendered safe for […]
