Problems solved by technology
However, due to the time spent cleaning the temperature probe, using a conventional AIC may result in an undesired number of operations for processing liquid food
Also, due to the aseptic nature of liquid food processing, certain cleaning products, such as those containing bacteria, are not suitable for cleaning temperature probes

Embodiment Construction
[0028] Specific implementation plan
[0029] The method and system of the present invention have special applications in the heat treatment system for machining, for example, liquid foods of milk. The method and system use a scraping sleeve that concentrically disposed on a temperature detector (e.g., a resistive heat apparatus (RTD) type) in the housing to scratch and remove the accumulation of liquid food at temperature. Sediments formed on the detector. The scraping sleeve is arranged to have a radial gap with the temperature detector such that the scraping sleeve can be scratched with the outer surface of the temperature detector without contacting and scraping the temperature detector. Additionally, the scraping sleeve has a radial slot such that the scratched sediment can be removed from the temperature detector by the radial slot. The advantage of using the scratch sleeve is that the sterile conditions of the liquid food in the housing are maintained, and the temperature de...

Abstract
A device and system for measuring a temperature of a liquid food product includes a housing (3) having an inlet (5) and an outlet (6) for allowing passage of liquid food product through the housing (3), a temperature probe (2) located within the housing (3) for providing a signal representative of a temperature of liquid food product passing through the housing (3), and a scraping sleeve (7) that is concentrically arranged over the temperature probe (2) and axially moveable along the temperature probe (2) to scrape and remove deposits from the temperature probe (2) that have been formed by accumulation of liquid food product on an outer surface (8) of the temperature probe (2).
Description
Technical field [0001] The present invention relates to a method and system for measuring the temperature of a liquid food, wherein a temperature detector is used to measure the temperature of the liquid food. Background technique [0002] During the processing of liquid food, the liquid food is heated and passed through a predetermined time to remove the pathogenic microorganism. Temperature detectors, such as a resistive heat apparatus (RTD) temperature detector, typically after the holding tube, to measure the temperature of the liquid food to ensure that the predetermined minimum temperature has been maintained when the liquid food is passed through the holding tube. Since high heat conditions in the tube, liquid foods may burn, and the layers of the combustion product may accumulate on the temperature detector, which is also referred to as fouling. Some liquid foods may have properties that lead to more easily combustion. As the thickness of the combustion product increases,...
