Deskripsi Proyek

Air Blast Freezer ( ABF ) is a common type of freezer, which is a refrigerated space filled with air around it. The advantage is, by utilizing convection flow, cold temperature can be spread to the corners of the room efficiently, but the heat transfer coefficient of air convection tends to be small so freezing needs to be done in a longer time due to the low heat transfer rate. The bigger the room, the less heat that can be transferred in a certain unit of time. Loss of weight from the product can also occur due to direct contact between the product and the air which is able to lift the water content in the food product, especially if the temperature and humidity allow it.

How Air Blast Freezer (ABF) Works
The cooling process uses a simple compressor engine by suppressing condensation which is transferred through the expansion valve before heading to the evaporator room. The evaporator itself is part of the cooler which is able to evaporate food to low temperatures. Inside the pressure of the refrigerant will be low pressure so that some high temperature or heat can be released.

This can happen when the gas refrigerant has been sucked in by the compressor while the condenser is only in charge of transferring heat to become cold temperature dew which then becomes liquid refrigerant.

And the next new task that will be carried out by the compressor is to lower the temperature to change the shape of the frozen ice. Evaporating refrigerant gas or freezing in this way is great for preserving food because it won’t change the taste.

Cold storage is a room that will be specifically designed with certain temperature conditions and will be used to store various kinds of products with the aim of maintaining their freshness. This cold storage will usually be built according to the area of the building on site. The size of the building on site will further ensure that the cold storage to be built will definitely be in accordance with the area of the building. Many consumers usually ask to come for a site survey with the aim of making sure everything is in accordance with the location.

How Cold Storage (CS) Works
First of all, before entering into the following article, we will first discuss the meaning and differences of Refrigeration, Refrigerant and Refrigerator. Refrigeration is a system that makes it possible to regulate the temperature until it reaches a temperature below the ambient temperature. The use of refrigeration is well known in air conditioning systems in buildings, transportation, and preservation of food and beverage ingredients. Refrigerant is a liquid or coolant used in cooling systems and air conditioners. Refrigerator is a refrigeration device that functions as a tool to lower air and room temperature/temperature (in general), this tool can also function to cool a device (in particular) for example: refrigerator, chiller, freezer, cold storage and others.
