As a chemical engineer of a food processing plant, you are asked to conduct material balances for a process where oranges are the feed and the final product is 40 kg/hr. of powder of orange juice. PROJECT: First, it is assumed that oranges contain in average 75% wt. of water, 10% of solids and the remaining are aroma substances and the weight of one orange is about 120 grams.

(1) Process Unit 1: From the filtration process, it is summed that only 90% of water and 85% of aroma of the oranges can be extracted as liquid from oranges. The rest is in the solid waste from oranges.

(2) Process Unit 2: In the evaporator, the dilute orange juice is now concentrated to contain only 25% water, the remaining being aroma substances. It is also assumed that 5% of the aroma of the feed has been wasted with the water vapor stream leaving the evaporator.

(3) Process Unit 3: The final step is a drying process where the dehydrated orange juice contains only 2% wt. of moisture and the remaining is aroma substances. It is also assumed that 3% of the aroma of the feed has been wasted with the water vapor stream leaving the dryer.

PROJECT CONTENT: I. DESIGN PROPOSAL

b. Flowchart representing the units, streams with all the known and unknown variables.

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
