Making the OIL with an air still

With using the Rick Simpson oil extraction method, once you strain the solvent through cheese cloth & into the rice cooker & boil it down, you end up with just oil.
However, you have no solvent left, its quite expensive & hard to find, So I bought an air still & intend to cook the mixture in the still until the last 100mls then place it in the oven @110deg C until no more bubbles are present. This way I get back 700mls of perfect solvent. Any comments?
