A cooking system for cooking a product flow utilizing steam. A supply of steam is provided at a supply pressure that is regulated by a control unit to a regulated pressure. The supply of steam is provided to a plurality of steam injection cookers which are positioned within a product supply pipeline that receives a product flow. The product flow is cooked as the product flow passes through the product supply pipeline and the plurality of cookers. Each of the steam injection cookers includes a steam modulator that controls the amount of steam injected. By regulating the steam pressure and the steam modulator, the control unit can modify the amount of shear created within the product flow and control the temperature of the fluid. The cooking system further includes a clean-in-place system that can inject a cleaning solution into the steam supply pipeline and the plurality of steam injection cookers.

A continuous differential-pressure steam sterilization system for a powder, and belongs to the field of material sterilization includes: a superheated steam generation system, a steam pressure and flow rate control system, a quantitative feeding system, an instantaneous differential-pressure sterilization system, a dust explosion suppression system, a sterile cooling system, a primary gas-solid separation system, a secondary gas-solid separation system, a sterile storage system, a steam recovery and reheating system, and a condensate recovery system. The continuous differential-pressure steam sterilization system shortens the thermal contact time and mainly accumulates the heat on the surface of the powder, rather than in the center of the powder, which reduces the damage to the nutritional quality of the powder. Comprehensive treatment methods such as superheated steam, temperature compensation and non-sticky inner lining are adopted to reduce the problem of powder binding, agglomeration, and even blocking in the pipe of the system.

A seal including a first portion having a first width that extends in a radial direction of the seal, a second portion that is joined with the first portion and having a second width that is smaller than the first width, and a first recess that is located in the first portion to reduce a width expansion of the first portion when the seal is compressed in an axial direction of the seal.

A machine for pasteurizing liquid or semi-liquid food products, including: a first container for the thermal treatment of a liquid or semi-liquid base product; a second container for feeding the liquid or semi-liquid base product, connected to the first, thermal treatment container, for feeding the liquid or semi-liquid base product; a stirrer for mixing the product in the first, processing container and mounted inside the first, thermal treatment container; a thermal system including an exchanger associated with the walls of the first, processing container and configured to release heat at the walls of the first, thermal treatment container, the machine wherein the stirrer is externally helically shaped and extends between a first, inlet end and a second, outlet end, so that as it rotates, the liquid or semi-liquid product is made to advance between the first, inlet end and the second, outlet end.

A method for the production of tomato concentrate is described, comprising the steps of: chopping the tomato so as to obtain chopped tomato with peels and seeds, subjecting the chopped tomato with peels and seeds to an enzymatic deactivation process, subjecting the chopped tomato with peels and seeds to an extraction process to obtain a tomato juice, subjecting said tomato juice to an evaporation process to obtain a concentrated juice and vapour, using said vapour to heat the chopped tomato with peels and seeds before subjecting it to the extraction process.

A food ingredient transfer device is provided. The food ingredient transfer device includes a dosing device configured to receive a food ingredient, and a first chamber that is provided with an inlet and an outlet for allowing the dosing device to pass through the first chamber. The food ingredient transfer device further includes a second chamber arranged adjacent to the first chamber for receiving the dosing device when it has passed through the first chamber, the second chamber being provided with an outlet for allowing the dosing device to pass through the second chamber and into an enclosure that contains a food product to which the food ingredient shall be transferred.

Heat exchange devices (30) and methods of using same are provided. In a general embodiment, the present disclosure provides for heat exchange devices (30) that are cooling devices having a double helical coil (32) in a phase-mixing-cooling section, a helical coil (36) in a phase-separation-cooling section, and a back-pressure valve (34) intermediate the two coils (32,36). The cooling devices provide maximum extraction of the heat content from a heated food product using a direct-injected liquid cryogen, and complete separation of the gaseous cryogen phase from the cooled product, while avoiding the formation of a stable foam. Hybrid direct-indirect cooling devices are also provided, as well as methods for using same.
