For food industry, the time of food storage and transportation process is not a short-term problem, but the relative balance of humidity in food preservation is also an important indicator to ensure food safety. Relatively balanced humidity directly affects the growth of colonies. For example: In the range of 95%RH to 91%RH, the number of colonies that can easily grow is Salmonella, Pollinella, Lactobacillus, Mold, and Yeast. The food preservation cycle is also related to temperature and equilibrium relative humidity. The cake with a relative humidity of 81%RH has a shelf life of 14 days at 27Â°C and 24 days at 21Â°C. If the equilibrium relative humidity is increased to 85%RH, these The indicator will be reduced to 8 days at 27Â°C and 12 days at 21Â°C. The equilibrium relative humidity of hygroscopic substances plays a decisive role. Balanced relative humidity is defined as the value of humidity obtained from the ambient air when the substance is not exchanged with water in the air. This definition is very clear, in order to successfully store and maintain these products, the environmental climate control and packaging must be carefully specified. At the same time, many foods are kept too dry and their taste will deteriorate. To address this situation, it is required to record changes in temperature and humidity in real time to ensure that food safety enters the mouth of consumers.
Constant temperature and humidity testing machine can effectively perform high and low temperature and humidity (constant) test on the product. The constant temperature and humidity box has the functions of heating, cooling, humidifying and dehumidifying. Put the product on the specified temperature and humidity, you can see the product's high temperature resistance, low temperature resistance, and resistance to humidity, so as to meet the requirements of the food storage and transportation process.
Gear Clock On Wall is a fashion item for both time and decorative function. You can see the gear moving and every gear has its own meaning, whatever hour, minute or seconds, as you can see the time going. Special Gear Clock not only including the table Gear Clock, but also the Wall Gear Clock. But hanging a gear clock on wall is like hanging a art work to increase the sense of art of home.
