ABSTRACT:
A liquid nutrient feeding system is provided including a first large volume receptacle for containing a bulk supply of liquid nutrient and a small volume liquid nutrient tank disposed below the receptacle. First conduit structure is provided for gravity feeding liquid nutrient from the receptacle to the small volume tank and nipple structure is disposed below the level of the small volme tank and communicated therewith by second conduit structure for gravity feed of liquid nutrient from the small volume tank to the nipple structure. Liquid nutrient level sensing structure is operatively associated with the small volume tank for admitting liquid nutrient thereinto from the receptacle only to a predetermined level in the small volume tank, whereby to provide a substantially constant head pressure of liquid nutrient in the second conduit structure to the nipple structure. Heating structure is operatively associated with the first conduit structure for heating the flow of liquid nutrient therethrough and structure is provided whereby the receptacle and tank and the first and second conduit structure initially may be flushed clean of liquid nutrient after depletion of liquid nutrient in the small volume tank and thereafter may be flushed with a cleaning and sanitizing liquid prior to introduction of a new supply of liquid nutrient in the receptacle.
