Unformatted text preview: the volume. 3. Turn on vacuum pump. 4. Turn on the steam, adjust for temperature. Observe water condensation dropping out from the exit pipe underneath. 5. After 10 min of evaporation, turn off the steam. Release air valve. Stop the vacuum pump. 6. Remove the concentrated materials from the kettle. Measure the volume and take concentrated samples for moisture and solids concentration analysis. 7. Clean up the kettle using tap water. 8. Measure the solids concentration using a refractometer and an infrared moisture analyzer. Questions: 1. Draw a block diagram showing all the input and output. Write balance equations. 2. Calculate the solid concentration in wet basis and dry basis in apple juice before and after evaporation. 3. Calculate the total solids in the input and output fluid, and calculate the loss. 4. Briefly discuss the accuracy of the data, and possible sources of the error....
