ABSRACT - [ Total Page(s): 1 ]ABSTRACT The cold storage structure was modified and evaluated for the storage of fruits and vegetables at the department of agricultural and bio-environment engineering of Kwara State polytechnic, Ilorin; the cold storage structure consists of the following components; compressor, evaporator, condenser, accumulator, dryer, etc. the variable factors are temperature and relative humidity. The cold storage structure was tested with the following fruits; watermelon, cucumber, tomatoes and apple .these samples were stored under two conditions (ambient and cold storage) for period of three da

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONEINTRODUCTION1.1 Background of the Study Fruits and vegetables are of great nutritional value. They are important sources of vitamins and minerals thus, essential components of human diet. Consequent upon this, there had been increased trade or commerce activities surrounding these commodities. Vegetable production forms a substantial percentage about 25% of the major food crops cultivated in the tropics and so it is the source of livelihood for a considerable section of the population (Idah, 2007).Fruits and vegetables in their fresh forms contain high percentage of water. Th ... Continue Reading
CHAPTER TWO - [ Total Page(s): 5 ]CHAPTER TWOLITERATURE REVIEW2.1 Development of Cold Room Structure for fruit and Vegetables Refrigerant and cooling of perishable food product is an important and fascinating area of application of heat transfer and thermodynamic. Refrigerant slow down the chemical and biological processing in foods the accompanying deterioration and the loss of quality. Cooling is defined as decrease in temperature of a substance or medium below its temperature of its environment. (Abubakar 2006) reported that most storage crops require low temperature and humidity (80 to 90) but at this humidity, ... Continue Reading
CHAPTER THREE - [ Total Page(s): 6 ]CHAPTER THREEMATERIALS AND METHOD3.1 Modified Area on the cold Storage. The following areas were modified on the cold storage structure in order to improve its performance. i. Compressor: the existing compressor was 1.5hp and was replaced with 2.0hp to improve the capacity of the evaporator ii. Capacitor: 30uf capacitor was replaced with 50uf capacitor to enhance the effectiveness of the 2.0hp compressor. iii. Condenser: 0.5hp condenser was added to the existing 2.0hp making it 2.5hp condenser in order to increase its performance. iv. Evaporation drier: the drier ... Continue Reading
CHAPTER FOUR - [ Total Page(s): 5 ]The result obtained from the effect of weight loss on daily time for bell Pepper, it was revealed that the rate weight loss under ambient condition is high the rate of weight loss in the cold storage structure is low.The result shows that the temperature in the cold storage decrease with time interval while the ambient temperature very with time interval depending to the atmospheric condition.Cooling rate:- this is determine by plot of temperature against time. ...

CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVECONCLUSION AND RECOMMENDATION5.1 CONCLUSION A cold storage system was modified for performance and the following conclusion were drawn; The percentage weight loss (PWL) varied between 0 – 41.7% . 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 ambient condition, The minimum temperature of 1.40C was recorded in the cold storage system when average ambient temperature was 27.70 ...
