A portable cold room storage was developed. The system was tested with different types of perishable crops under different temperatures. The system is made up of two units, one,the evaporating unit that is where the produce was stored; it is made up of steel material with 79mm by 45mm in length and breadth.
While the second unit is the trolleys, the system consists of a control switch that is calibrated to suit any type of produce stored in the system.
It contain a separate basement which consist of compress or, 1/6 cooling fan 1/6 connected together into the evaporating unit. This system was also constructed with lagging material which consists of A and B formula called polytherine.
The ambient temperature was 35which have temperature range between30. The electricity power requires running the cold room storage system is 220 to 250v. Hence, the system is effective for the storage of perishables at favourable conditions for every home.

INTRODUCTION
1.1 Need for Cold Storage of Agricultural Products
The term ‘cold storage ’refers to the storing of agricultural products in a refrigerated atmosphere. This means adequate amount of heat is removed from the storage container or room to help keep the item in often food fresh to delivery, long or short term storage.
Cold storage help prevent spoilage of food and other items meat for consumption, and it can be used in a variety of other setting such as in hospitals, warehouses, and any where else that stores product is in need of preservation .when transporting goods, refrigeration trucks are often used to keep items cold throughout the transportation process.
The room or compartment system in which items are stored for cold storage must be insulated properly for several reasons. The insulation helps maintain a particular temperature within the storage units. it help prevent cool air from escaping from the unit, which would otherwise lead to higher refrigeration costs and energy waste, and it help prevent the temperature outside the storage unit infiltrating into the storage.
In many cases, the temperature within a cold storage unit can be manipulated by adjusting a thermostat, a cooling unit and packing procedures should facilitate easy cooling of products being transported. This method is commonly used to transport perishable foods, flowers meats, and even human organs intended for transport blood is also refrigerated during transport so it can be used later for blood transfusion.
Home refrigerators can be considered cold storage units as well .refrigerators are used to prolong the life of food to be eaten, and they prevent spoilage of perishable food ,in the past ;ice boxes were used instead to keep food cold, but this method was inefficient as regulating the temperature of school structure was often difficult, some types of ship features cold storage units in which temperature can be regulated, in the past fish that were cold were stored in container filled with ice, and the ship[would have to return to port before he ice could melt and allow the fish to spoil.
