Cold Storage Temperature and Humidity Monitoring System is the most economical solution which can be installed in cold storage facilities for measuring temperature and humidity. The device is basically plug and play device that does not require any additional installation and commissioning which makes this different from other solutions available on the market. Temperature and humidity monitoring for refrigerators which are used for storing, medicines, vaccines. Humidity and temperature monitoring of warehouses where temperature-sensitive products are stored like chemicals, fruits, vegetables, food, medicines.
Importance of Temperature and Humidity Monitoring:
Freezing rooms are designed to maintain a constant temperature and humidity level to prevent microbial growth, moisture loss, freezer burn, and deterioration of the quality of frozen products. An increase in temperature and humidity can have adverse effects on the products, such as:
1. Microbial growth: An increase in temperature and humidity can lead to the growth of bacteria, viruses, and fungi, which can contaminate the products and cause foodborne illness.
2. Moisture loss: High humidity levels can cause moisture loss from the products, leading to freezer burn and dehydration.
3. Deterioration of quality: An increase in temperature and humidity can cause changes in the texture, color, and flavor of the products, reducing their quality and shelf life.
4. Safety concerns: High temperatures can cause the products to thaw, leading to the growth of bacteria and increasing the risk of food poisoning.
Methods of Temperature and Humidity Monitoring:
A real-time monitoring system involves a lot of sensors like humidity, temperature, and pressure sensor among others. All the sensors collect data continuously at already specified intervals known as sampling intervals. The sampling intervals can range from a few seconds to hours based on the criticality of the parameter being measured. The collected data of all the sensors are continuously communicated to the central base station. The base station transmits collected data to the internet. The base station analyzes the data continuously in case of any alerts. If any parameter exceeds fixed levels, alerts like SMS, voice call, or email will be generated to operators.
Types of real-time remote temperature monitoring systems
There are different types of monitoring systems based on the technology of the device which is being elaborated on below.
1. Remote Temperature Monitoring Device:
Remote temperature monitoring devices are designed explicitly for remote, unmanned facilities. They come equipped with sensors that measure temperature and humidity levels and a powerful transmitter that sends real-time data to a cloud platform. The data is accessible from anywhere, and you can set alarms to alert technicians if the temperature or humidity levels exceed the predefined range.
2. Wireless Sensors:
Wireless sensors are similar to data loggers but are equipped with a wireless transmitter that sends data to a receiving unit or cloud platform. They can be placed at different locations inside the freezing room to monitor the temperature and humidity levels continuously. Wireless sensors provide real-time data and alarms, making it easier to detect temperature or humidity variations and take corrective action.
3. Handheld Thermometers:
Handheld thermometers are commonly used in the food industry to measure the temperature of frozen products. They are portable, easy to use, and provide instant readings. The thermometer’s probe can be inserted into the product to measure the temperature accurately. However, they do not measure humidity, and the readings are only taken at the time of measurement.
4. Paper-Based Temperature Monitoring:
Paper-based temperature monitoring is a cost-effective method to monitor the temperature and humidity of frozen products. The temperature and humidity levels are monitored using paper-based indicators that change color when exposed to the defined range of temperature or humidity. Paper-based monitoring helps to detect temperature or humidity variations over time, providing a visible indication of any deviations.
5. Data Loggers:
Data loggers are electronic devices that are used to record temperature and humidity readings at a specific interval. They are small, portable, and can be placed inside the freezing room to monitor the temperature and humidity levels continuously. Data loggers can be set to alarm if the temperature or humidity levels exceed the defined range, providing an alert to take corrective action. They store the readings in their memory and can be downloaded to a computer for analysis and documentation.
Conclusion:
Temperature and humidity monitoring are essential in a freezing room to maintain the quality and safety of frozen products. The methods of temperature and humidity monitoring include data loggers, wireless sensors, remote temperature monitoring devices, handheld thermometers, and paper-based monitoring. Each method has its advantages and limitations, and it is essential to select a method that suits your freezing room’s requirements. Proper temperature and humidity monitoring can help to prevent product deterioration, reduce waste, and ensure customer satisfaction.
