Introduction The fresh fruit and vegetable is important and remarkable point in supply chain. The fresh fruit and vegetable supply chain is characterized by many national and international small and medium-sized enterprises at the production stage. And also the consumer demand for fresh fruits and vegetables all over the year is a special challenge of this chain and this chain strongly impacts all of the particularities. Therefore, the adoption of new Technologies and new opportunities for improving information logistic can have important benefits to meet the fresh fruit and vegetable’s conditions. One important benefit is the collection information and determine an impact on the strategies process efficiency of enterprises. And also we can see demand for fresh fruits and vegetables on graph. The other factor is the transport of fresh fruit and vegetables is a complicated topic. Diffrent type of fruit and vegetables have widely differently requirements for their safe transportation conditions. Movement of produce from source to market provides a straightforward survey of large variations in transport distance, given that many fruits and vegetables are both produced domestically and imported. Srotage and distribution of fresh fruit and vegetables is very important and critic point that should focus for making satisfied demand requirements and be successful on food marketing chain and especially for quality. We should be flexiblity for new technological innovations and can implementation for get advantages. There is so much factors that affect fresh fruit and vegetables.

Despite variable heat leakages which may occur in various parts of the system, and the unavoidable increase in the circulating air temperature at return compared with delivery.The circulating cooling air should therefore only be required to remove respiratory heat of the produce and the heat exchanged via exterior surfaces. A high velocity of circulating air should be unnecessary and in fact undesirable. Cooling air in modern refrigerated vessels and containers is usually circulated vertically, from the deck/floor, upwards. The system is designed to produce be equal air pressures ove the full area of the cargo space. • Chlorine dioxide (ClO2) This is a water-soluble yellowish green gas with an odour similar to that of chlorine. It is highly effective at neutral pH. Its reactivity is, however, reduced by the presence of organic matter.

ITC has introduced information technology into agricultural business in India. . The eChoupal kiosks have been set up to facilitate a new supply chain. This new technology-integrated supply chain has addressed several difficulties in the past. The following sections will lay out the inefficiencies of the traditional supply chain management; describe the ITC eChoupal Initiative; and analyze how eChoupal enhances the soybean supply chain. The future platform will also be discussed.
Monsanto Vegetable Seeds has placed the supply chain organization within global manufacturing and supply chain. The of this group reports directly to the President of the division and the organization is about 1,000 employees strong. The supply chain heads are paired with their commercial counterparts and their marketing counterparts. This is hand...
... heat. The tube-within-a-tube is constructed by placing one tube within a second tube. The shell and tube condenser uses cool water in the tubes and feeds the hot refrigerant in and condenses the refrigerant when it comes in contact with the tubes. Evaporative condenser uses open spray or spilled water to cool a condenser.
As a result of the design parameters from the experimental column, the following design is proposed: the column will run at a vapor velocity of 4.85 ft/hr and will have a HETP of 4.30 inches. This will result in a packing height of 38.7 feet. The reboiler will have an area of 113.52 ft2 and the area of the condenser will have a value of 45.54 ft2 in which heat exchange will take place.
In warmer climates such as Egypt they used techniques as evaporative cooling, “if water is placed in shallow trays during the cool tropical nights, its rapid evaporation can cause ice to form in the trays, even if the air does not fall below freezing temperatures”. Although refrigeration developed in the 18th century it wasn’t until the mid-19th century when the first refrigerator built using vapor technology was build by American John Gorrie in 1844. A few years later commercial refrigeration was introduced as well as vapor compression technology which was the beginning of our modern refrigeration. Later that century ammonia was popularized as the evaporation chemical in refrigeration. All the trials and tribulations of refrigeration where all stepping stones to the 20th century and the introduction of modern refrigeration as we know it
[Randel (1932) investigated an NH3/H2O absorption refrigeration cycle employing the principle of supplementary agent for pressure equalization in the evaporator (Qué es? Not Clear). In this case the supplementary agent does not circulate with the cooling agent (What is the cooling agent? Write with your own words. Don’t try to copy full sentences) [Improve the writing style of this part]. The heat of absorption is utilized in the desorber to reduce the heat input [how?]. As shown in Figure 5, the major components of the cycle are the same as those ...
Central air units incorporates 2 main parts: the condenser, sometimes placed outside the house on a concrete block, and also the evaporator, situated simply higher than the chamber within the plenum (the giant metallic assembly covering the chamber and evaporator units). The evaporator is cooled by the condenser employing a special fluid known as Freon; while not Freon, there's no cooling.
Food industry can be chartered by low margin industry, while along with the shift of power from the manufacturer to the purchaser, the price and demand became flexible, and the product variety increased.
Ice based technology also known as ice storage air conditioning is the process of using ice to store energy. This method is used in order to decrease the energy usage cost by transferring the energy consumption from high ...
Refrigeration Refrigeration is defined as “The process of removing heat from an enclosed space, or from a substance, to lower its pressure.” (First website given in bibliography) In simpler terms, it is removing heat from states of matter in order to keep them cooler. The basic need for refrigeration is to cool food and beverages, as they often get spoilt if the temperature is high. Before actual refrigerators and other such mechanical systems were introduced, it was very common for people to cool their food with ice and snow.
First, they get their own system to track down their inventory. If they recognize the deficiency in its inventory on their system, they can easily find out how to manage inventory to catch customer’s demands. It lessens the risk of occurrences of their out-of-stock events. Their system also includes supermarket’s supply chain. It does not focus on just inventory, but it can show managers that their all operations are working well by Wegmans’s strategy. Managers always check out its own supply chain and producing department. For example, they can log all their food’s record by mobile computing tablets. Manufacturers and date of manufacture are registered by all records associated with grocery. It can not only reduce staff requirements and expenses, but also gain
Coolcargo and Frito-Lay implemented technical solutions for agricultural-products transportation following customers’ requirements. Coolcargo developed a transport-system for maintain fresh asparagus at controlled temperature from production site in Thailand to final destination in UK (UOL, 2013). Frito-Lay developed a global agile supply-chain for manufacturing and distributing salty-snacks to end-customers that allows processing agricultural-products in less than 24 hours for flavor guarantee (PepsiCo, 2013).

Process bc : This high pressure and high temperature vapour then enters a condenser where the temperature of the vapour first drops to saturation temperature and subsequently the vapour refrigerant condenses to liquid state .
