Abstract: A storage tank for storing of liquid food products partially processed before final processing. The tank is constructed with smooth germ-free internal surfaces to avoid recesses in which the stored food product or disinfecting fluids can be entrained and contaminate the tank and food product therein. A dispersion device in a conical top of the storage tank homogenizes the food product to be stored when introduced in the tank. The same dispersion device disperses treatment liquids introduced into the tank to effect dispersion onto all the inner surfaces for treatment thereof.
