1, pot heat distribution hot water spray system at the four corners of each tray treatment tank are equipped with a series of nozzles disposed between each layer of the tray, and gave a very wide range of spray patterns. From the nozzle mounted vertically on the four corners of each tray, the continuous spray of water, so that the tank temperature at all stages of the sterilization process remain very stable, to ensure that the change in the value of F and cooking over such phenomena is reduced to a minimum limit. 2, spray-temperature retort packaging for a variety of different cooling process due to not inject cold water directly from the pot, so the fragile glass packaging, you can take gentle cooling speed, avoid excessive temperature Great cause broken bottles. This feature is also suitable for shellfish, such as clams, cool temperature too much, or heating temperature too much will cause the shell to break. 3, the control system A, all the time by sensors and automatic control valves. B, pressure and temperature were digital display. C, using the recorder records the temperature and pressure curve. D, pressure sensors, temperature sensors, PLC, HMI and other use of imported parts. 4, spray-temperature retort heating up fast due to the pot and only a small amount of recycled water, and high efficiency (up to 98%) heat, so food heating speed, under normal circumstances, the steam pressure is 0.6Mpa when food rose from 20 degrees 121 degrees, 8 minutes, so you can maximize the flavor and color retention of food, but also can reduce energy consumption. 5, a sound pressure control, pressure balancing system for sterilizing gas packaging is critical to containing the gas sterilization packaging, especially in the heating or cooling phase, requires precise pressure control. The control system can handle tank for continuous monitoring of temperature and pressure, and the pressure in the tank so that it corrects the pressure within the package accordingly. For containing any percentage of air or gas filled packaging under vacuum or in a sealed package can be sterilized, or the contents of the packaging without causing damage or deformation. This system differs from other systems can be applied to any product all kinds of pressure patterns pre-programmed into the computer program input. 6, indirect heating and cooling, circulating water to prevent secondary pollution indirectly heated or cooled through a plate heat exchanger, to prevent secondary pollution. 7, retorts using PID temperature control system based on different food sterilization conditions require at any time to set a different temperature and cooling procedures, you can use a multi-stage heat sterilization ways to make food affordable heat to a minimum limit to save as perfect its flavor, texture and color, so that every kind of food can be sterilized conditioning in the best condition. Accurate sterilization temperature (± 0.1 ℃) due to high temperature and pressure processing method to avoid generating cooking odors.
