    The problem is in the amount of reflux in the column, your temperature gradient is creeping up the column and pushing off all the reflux. By adding more wash

      The problem is in the amount of reflux in the column, your temperature gradient is creeping up the column and pushing off all the reflux. By adding more wash to the system you are reducing the temperature thus allowing more reflux to remain in the column.
      there are three fixes, #1 is to lengthen the column to allow more reflux(cheap solution). #2 is to hold back on the amount you recover to allow more reflux to remain behind(requires 2 or 3 small holes drilled in the standpipe in the condenser section). #3 is use a temperature activated valve to control the cold water flow through the condenser and reflux section(costs about $275us and requires a coil inside the column. this is the ultimate fix.).

      Some friends of mine tried to make this still( this is just a sketch) but they are having problems with the temperature.The temperature can be stabile for 30 min and then the temperature rises so they have to adjust the valve which lets the wash into the main column.Then it stays stabile for another 30 mins.(the alcohol holds 94-95 %) What can be wrong with the still?(it seems like the watervapourpressure/temperature want stay stabile)
