dry up all the moist. The other dry berries were held in bins 1-16. They would go through one of the three destoning units (processing up to 1500 bbls.) and then go to the dechaffing units. In all, wet berries would be processed through dryer-included system and dry berries would be processed through other machines which frequently made both berries process at the same time through the system.
Process Fruit Receiving
At the beginning of the process of RP1, bulk trucks that carry process berries arrived randomly. Prior to unloading, they were weighted and recorded, and 30lbs of samples which had been through small version of cleaning and drying process were taken to estimate the percentage of the truck’s net weight made up of clean as well as dry berries.
The berries were graded acc
dry berries so that they can hold both water harvested and dry berries.
About this case, we went through a procedure to get the best solution regarding adding new dryers and converting bins. Moreover, we discussed our own creative solutions considering the trend of increasing water harvested berries.
2. In the current flow of the process, identify the bottleneck area(s). What are the causes
and freeze drying processes are used for products with delicate flavours and textures like coffee granules, eggs, prawns and vegetables. The process involves freezing, and evaporating the ice away, under reduced pressure. It is an expensive process but gives a produce which is high in flavour and palatability. Milk may be dried on rollers or by spraying concentrated milk into hot air chambers.

2. 2. Extraction
After the fermentation, the microorganisms(Alcaligenes latus) are filled with PHB in their body. These PHBs have to be separated from microorganisms to make final product. To separate PHBs from biomass, they are extracted from biomass by using solvent. These PHB extracted solvent will experience washing and drying process. After that, PHB can be precipitated as white powder.

6. Barrier Meta
process berries arrived at RP1, loading 20~400 bbls. These trucks arrived randomly and average truck delivery was 75 bbls. Truck usually took from 10 minutes to back a truck onto a dumper( 6 trucks/ hour) and they moved to five dumpers. So total dumps capacity is 75 (bbls/truck) X 6 (truck/hour) X 5 dumps = 2250
Second, temporary holding bins capacity :

3D printing
3D printing or additive manufacturing (AM) refers to any of the various processes for printing a three-dimensional object. Primarily additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source.
Basic principles
If the
Water-harvested berries were held in bins 25-27, and bins 17-24 held either wet or dry berries. Since water harvested berries did not need destoning, they went straight towards one of the 3 dechaffing units (holding up to 1500 bbls. per hour each). Then, these wet berries were taken to the drying units at different rates for those expected to be loaded into bulk trucks (200 bbls. per hour per dry
