A method and apparatus for mixing and feeding a volatile liquid, such as liquid ammonia, with a non-volatile material, such as a fabric finisher; the method comprising the steps of feeding the liquid to a mixing vessel and, by volatilizing a portion of the liquid, cooling the vessel and, while continuing to feed the liquid and after the cooled liquid has reached a predetermined level in the vessel, adding to the liquid a measured amount of non-volatile material, continuing the liquid feed until the liquid level reaches the measured amount, agitating the liquid and material and, as the liquid volatilizes, adding additional of such liquid to maintain the liquid level at the measured amount; the apparatus comprising a mixing tank having a cover, a coolant coil in the mixing tank, first feed means having a valve for feeding a volatile liquid to the tank, second feed means having a valve for feeding a non-volatile material to the tank, a float and switch in the tank for controlling the liquid feed valve, a float and switch in the tank for controlling the non-volatile material feed valve, a discharge line for discharging the mixed material from the tank to a trough in a fabric treatment chamber, a valve in the discharge line, electrical means for opening and closing the valve in the discharge line and for closing the liquid feed valve when the discharge valve is open and closing such liquid feed valve when the discharge valve is open, the floats in the tank opening and closing the liquid feed and material feed valves when the liquid in the tank is at pre-set levels.
A method for mixing a measured amount of nonvolatile material with a measured amount of volatile liquid and for maintaining the proportion of such measured amount of material in such measured amount of liquid at substantially a constant level, the steps comprising, feeding said volatile liquid into an insulated vessel and by volatilizing a portion of said liquid and by circulating a coolant to lower the temperature of said vessel and said liquid therein, while continuing to feed said liquid into said vessel and after said liquid at said lowered temperature has reached a predetermined level in said vessel adding to said liquid in said vessel said measured amount of non-volatile material, continuing said feed of said liquid into said vessel until the liquid level of said volatile liquid in said vessel reaches said measured amount, as said liquid volatilizes, adding to said vessel additional of said liquid and maintaining said volatile liquid in said vessel at said measured amount and, while feeding said liquid and said non-volatile material to said vessel, agitating said liquid and said non-volatile material in said vessel.
