Features And Methods Used In Cold Storage For setups that deal with perishables in Hong Kong, costs that come with cold storage are key among the unavoidable expenses they have to contend with. This sort of storage becomes hard to reflect on particularly where one has to factor in issues such as expansion, relocation and even transportation. Nonetheless, before looking into the type of storage container to acquire, it's important to understand the basic features attached to the systems as well as the different refrigeration methods they use. Every cold storage must have insulation, a vapor barrier, a valve and a refrigerant. During the shipping of cargo, leakages may occur from within the container and when this takes place, the temperatures may increase and therefore lead to food spoilage. To avoid such problems, the containers have to be fitted with insulators. The materials used in the insulation processes can either be vermiculite or fiber glass, both of which are moisture resistant, inexpensive, and easy to install. The two also have low conductivity and once they are applied in the container, they help ensure that the quality of the perishables is not affected. Similar to other storages, cold storage in Hong Kong also comes with a vapor barrier that has to be positioned between the insulation and the outside wall of the container in order to limit the inflow of moisture. Ammonia gas is applied as a refrigerant whereas a thermo expansion valve regulates gas flow. When the desired temperature is attained, the thermostat in the valve closes. All these features play a huge role in enabling effective functioning of cold storage facilities. Refrigeration units also employ three different methods in the cooling process. 1. Electric Cooling Most of the refrigerated containers that have static storage also provide electric cooling. Containers that operate using this type of system simply need to be plugged in to start running. The high insulation level helps ensure that the containers utilize minimum electricity, and this makes them very beneficial to businesses. 2. Cryogenic Cooling With this type of cooling, the refrigerant uses ice in form of frozen carbon dioxide, and this helps maintain certain temperatures all through the trip. Basically, when the ice melts, it cools down the container as it evaporates and it is also vented out in the process. Cryogenic freezing is particularly ideal for long distances seeing as it can be used to keep food fresh for two weeks or more. 3. Redundant Refrigerated Containers During shipping, hitches may occur at one point or another and in the event that counteractive measures are not put in place, spoilage may result. Redundant refrigeration was designed with this idea in mind. In this method of refrigeration, two units are positioned in opposite ends of a
container. The units operate automatically meaning that in case one stops, the other starts up and takes up the job to ensure that the environment stays the same throughout. For businesses dealing with perishables, obtaining Cold Storage In Hong Kong is not optional because it's only when you have such storage that you can be sure to maximize on productivity and business expansion.
