The appearance of UHT technology for fruit particleThere are two kinds of sterilization method for beverage with fruit particle. One is sterilization retort, it means after filling, the PET bottled or aluminum can product will be put in a basket and then put into the sterilization retort for spraying with high temperature water or steam; another one is using a heating pot to heat the fruit pulp in small batches before filling and then make the filling process. For the first method, the product packaging material must be high temperature resistant material, and product PH value has important impact on material cost. If the PH value is more neutral, it may need much higher sterilization temperature for the product, so the packaging material cost should be much higher. No matter using the sterilization retort or the equipment has low sterilization capacity, the processing capacity of each batch is limited and cannot supply product continuously. It needs to be replaced in the middle of production. In addition, when the materials are heated through the cooking pot, the temperature will be uneven. Sometimes the central temperature in the pot does not meet the standard, which may lead to risks such as incomplete sterilization. In addition, during the heat transfer and heating process of the materials through the pot wall, the internal surface of the cooking pot is prone to burn and scale, resulting in difficult cleaning. The general shortcomings of the above equipment gave birth to the research and development of UHT technology.
