Ch.E. 421 Problem Set (Batch Drying) 4 Ch.E.a/b 13-15 November 2012 The solution of the problems are to be submitted as a team report at the end of the period. Please include honor code and the individual contribution of each team member. 1. A wet solid is dried from 36% to 8% moisture in 5 hours under constant drying conditions. The critical moisture is 14% and the equilibrium moisture is 4%. Calculate the time needed: a) To dry from 8 to 5.5% moisture b) To dry from 30% to 15% moisture c)

However‚ it’s important to constantly rotate your stored food‚ buying new freeze-dried meals‚ placing them in the back of the shelf and consuming the older food in front. Thus always maintaining a freshly purchased and long lasting supply of survival food. Homemade Dehydrated Food Is Also Excellent Long-Lasting Survival Food

water particle easy and decrease faster ‚leading to a short drying time. The measurement of the moisture content is based on the weight sample which is inversely proportional with the temperature and time ‚ though the temperatue is kept constant throughout the experiment .Thus we can determine the drying rate of the sample based on the data obtained from the experiment ‚the mass and moisture content is decreasing with time whereas the drying rate is varying rapidly with time.

vegetables and fruits. If an oven is used‚ make sure there are numerous drying trays to fit on the oven’s racks‚ an accurate oven thermometer‚ and a small fan that is electric. The oven temperature should be 140 -degrees for up to eight hours for vegetables‚ fruit from four to five hours‚ and five hours for jerky. The 140-degrees oven heat is approximately the same heat as keeping the pilot light on‚ with scorching occurring if longer drying times are used.If freezing is used afterwards to kill possible insect

fruits in the EU. Dried fruit has a long shelf life and can therefore provide a good alternate to fresh fruit‚ allowing out of season fruits to be available. Drying is a good way to preserve fruit in the absence of refrigeration. Dried fruit and vegetables are whole‚ cut‚ sliced‚ broken or powdered‚ but not prepared further. In addition to drying‚ certain preservatives may be added to maintain the equality. For instance‚ sulphur dioxide is added to prevent fruit discolouring. The use and content of

the hot air drying kinetics model In the hot air drying‚ moisture ratio at three temperatures of 40‚ 50 and 60°C was obtained and fitted with the existing models in Table 1. Table 2 shows the coefficients and statistical indicators related to these models in the hot air drying method. The Page and modified Page models better than other ones predict moisture ratio based on the temperature of the dryer and the drying time. Values of R2‚ χ2 and RMSE for the two models in the hot air drying method were
