Provided is an automatically rotating, high-pressure sterilizer 10. A vessel 110 thereof has a vertical axis 151 that inclines to a horizontal rotation axis 150. A processing chamber 114 in the vessel 110 has a smooth and non-protruding inner surface 114a or has a mechanical stirring element for stirring products 100. The vessel 110 comprises at least: components for supporting and rotating the vessel 140-144, a first connector 120, temperature-controlling components 121-123, processing chamber 114 supplying components 131-134, sensor components 145, 150, and a PLC-type electronic controller 163. Also provided is a corresponding processing method. The present invention achieves high quality while having low operation costs, and is suited for high production volumes. |

1. An automatic rotating autoclave (10) for use in saturated steam conditions for the pasteurization-sterilization of low moisture products (100) of particulate type, with the added function of agitator-blender, being the complete treatment chamber (114) a cylindrical vessel (110) with hermetic closure of a type of double jacket (111, 112) with cavity (113) and moved by an electrical motor; wherein
said vessel (110) has the longitudinal axis (151) inclined to the axis of horizontal rotation (150), where the said treatment chamber (114) of said vessel (110) has the inner surface (114a) smooth, without protuberances or elements for the mechanical agitation of the product (100), and where the said vessel (110) has at least:
means for supporting and rotating it (140-4, 150);means for the temperature control (120-3) of the said cavity (113) of the double jacket through a rotary coupling (120) positioned in connection with the said axis of rotation (150);means to supply (130-4, 137) the said treatment chamber (114) alternately with steam injection or vacuum extraction through a fixed coupling (130) which is positioned in connection with the said axis of rotation (150), on the opposite side with respect to the said means of temperature control of the said cavity (113, 120-3), also with a system of filtration and diffusion (137, 138) inside the chamber (114) which is connected with the said fixed coupling (130) and of a self-cleaning type;sensor means, allowing the detection of the rotation and the position of the vessel (110) with respect to the horizontal axis (145, 150);an electronic controller (163) of a PLC type which is connected in an integrated way at least to said means for the temperature control (113, 120-3), for supplying (114, 130-4), for supporting and rotating (140-4) and at least to said sensor means of temperature and pressure (160-2) and rotation (145) in order to monitor and automatically adjust the values of pressure and temperature in the chamber (114) so as to achieve and maintain the correct treatment conditions of the product (100) even during the rotation of the vessel (110) and with saturated steam, the said controller (163) adapted to manage automatically the operation of the autoclave (10) and the whole treatment process (20). |
