Labor-intensive batch processing plant

In any design consideration, there are trade-offs between capital and labor. A batch process is more labor intensive than a continuous processing plant for the same amount of chemical product. A continuous unit that is highly instrumented and computer-controlled is more capital intensive than one designed with a minimum amount of instrumentation. A plant designed... 

This type of manual control is simpler and less expensive, and less expertise is required than antomatic control systans. It can be applied to small plants (mainly batch systans) and on easy-to-dry-materials. However, mannal control is not recommended in the case of large drying processes and where good control is required to stabilize the process against any disturbances. It is also labor-intensive.
