A method for producing a pur&#xe9;e from a food product, comprising the following steps: The step of de-activating the enzymes comprises the step of passing an electric current through the pur&#xe9;e between electrodes of a first ohmic heater ().

Plant and method of production of puree

An ohmic heater for heating a food product, including: a rectifier () for rectifying the supply voltage; an inverter () including controlled switches (); a pair () of electrodes that can be positioned in contact with the food product to be heated, said inverter () being operatively interposed between the rectifier () and the pair () of electrodes; a device () for determining an oscillating voltage (X) generated by the rectifier (); a system () for regulating the closing duration of the switches () of the inverter () at least as a function of the corresponding voltage (X) generated by the rectifier () and determined at a given time instant by the device () for determining an oscillating voltage (X).

Method for the production of apple sauce including the following steps:

Method and plant for the production of apple sauce

Disclosed is a concentration plant with differently-functioning sections. The plant comprises a vertically-developing external tubular sheath (), internally of which are comprised: a heat exchanger (), in which a heating fluid coming from a fluid inlet mouth () circulates, which heat exchanger () is defined by a lower plate () and an upper plate () on which lower plate () and upper plate () upper and lower open ends of a first vertically raising tube bundle () and a second descending tube bundle () are fixed, in which first and second tube bundles () the product to be processed circulates; a supply chamber (), arranged inferiorly of the lower plate (), which sets an inlet mouth of the product () in communication with the lower ends of the tubes of the first tube bundle (); a pressurised upper chamber (), arranged superiorly of the upper plate (), which sets in mutual communication the upper ends of the tubes of the first tube bundle () and the second tube bundle (); a separation chamber (), which is arranged internally of the sheath () and inferiorly of the lower plate () and in which the lower ends of the tubes of the second tube bundle () open, a product outlet mouth () being afforded on a closed bottom of the separation chamber (), and an outlet opening () being afforded on a lateral wall of the separation chamber () for exit of steam generated during product concentration.
