The working temperature for evaporator = 80C, the working temperature for condenser coil = 330C
Converting to Kelvin
(ii) Cooling Rate
Plot of temperature against time.
(iii) Physiological weight loss
A weighing balance was used to determine the weight of the stored sample both in the cold room storage condition and in ambient condition for 3 days. The change in weight of the sample was estimated. The percentage weight of the samples was estimated. The percentage weight was estimated using the formula as expressed.
(iv) Colour Changes and Firmness
The changes in colour of the samples were noted both in the cold room storage and in the ambient condition. The physical texture of the samples was examined and noted and the difference in the firmness was also noted after storing the samples in the cold room storage and in ambient condition respectively.

ABSRACT - [ Total Page(s): 1 ]ABSTRACTSA 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 whi ...

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONEINTRODUCTION1.1 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 ho ...

CHAPTER TWO - [ Total Page(s): 6 ]2.5 Indoor Storage of Fruits and Vegetables There are many areas in dwellings that naturally provide, or can be adapted to provide, a variety of temperature and moisture conditions for storage. Assess your specific situation; if possible, use a thermometer to monitor temperature in various area of your building during fall and winter to find locations that are convenient and most readily adaptable for storage food. Any spot that is sufficiently and evenly cool (32 – 60 ... Continue reading---
CHAPTER FOUR - [ Total Page(s): 6 ]Figure 4.5: Effect of temperature against time interval both in the Cold Storage and under ambient condition The result showed that the temperature in the cold storage decrease within the range of 29-1.40C with time interval of three (3) days while the ambient temperature very with time interval depending to the atmospheric condition. ...

CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVECONCLUSION AND RECOMMENDATION5.1 Conclusion A cold storage system was modified for performance and the following conclusions were drawn from the evaluation conducted. The percentage weight loss (PWL) varied between 0.06 – 61.57% . Maximum weight loss was found in ambient condition where as minimum (0.06%) was found in the cold storage system. The percentage weight loss was found increased with increase in storage period for both cold storage system and ambie ... Continue reading---
