Abstract: A complete self-containing multipurpose dairy processor unit in which a liquid is treated including a hot-water or steam generator and a heat exchanger immersible in the liquid to be treated and selectively feedable when immersed in the liquid being treated with hot water, steam or cold water depending on whether heat is to be transferred to the liquid to be treated or removed from the liquid to be treated, the hot water or steam being produced by the generator device. A generator including a turbine produces a flow within the liquid to be treated to cause the liquid to pass over the heat exchanger. The turbine is a variable-speed turbine which forces the liquid from a location below the heat exchanger upward into and through the heat exchanger.
Abstract: A plant and method for coagulating, pasteurizing and cooking food having a liquid or pasty base including a plurality of stations, devices for implementing a processing step on the food in each station, at least one container into which the food to be processed is initially placed, and devices for enabling the container(s) to be successively positioned in the stations to thereby subject the food in the container(s) to processing by the processing devices in the stations. The processing device in at least one station includes a variable-speed dynamic radial heat exchanger for affecting the temperature of the food.
