Description

Fresh rice production line and pressurization sterilization device thereof Technical Field The utility model relates to the field of self-heating rice, in particular to a fresh rice production line and a pressurizing and sterilizing device thereof. Background Along with the acceleration of social progress and life pace, the requirements of people on food industrialization products such as prepared vegetables, self-heating rice and the like are higher and higher. In recent years, the development of the prepared vegetables is faster, intelligent and automatic factories are already provided, and the industrial production of the self-heating rice has certain challenges due to the fact that the self-heating rice needs to complete more steps of removing impurities in the rice, carefully selecting, soaking, cooking and the like. In the existing self-heating rice processing, the rice grains in the self-heating rice are partially processed by adopting a remanufacturing process, namely, the rice is crushed and then mixed with starch (such as corn and potato starch) and is extruded into rice grains. A part of the rice and water mixed cooking process is adopted, but the process design is simpler, so that a plurality of problems exist. For example, the self-heating rice production line comprises a rice washing device, a rice soaking device, a filling device, a microwave cooking device, a film sealing device and a secondary curing sterilization device, wherein the rice washing device conveys washed rice to the rice soaking device, the rice soaking device conveys soaked rice to the filling device, the filling device quantitatively conveys soaked rice and nutrient solution to a cooking box, the microwave cooking device heats and cooks the rice and the nutrient solution in the cooking box, steam is actively discharged after the rice in the cooking box is uniformly cured to accelerate the nutrient solution in the cooking box to be dispersed, the film sealing device packages the cooking box for containing cured rice to obtain a semi-finished cooking box, and the secondary curing sterilization device performs high-temperature sterilization and secondary curing. In the process production line, the filled rice is not subjected to effective sterilization treatment, and is sterilized only by secondary curing after cooking, so that a good sterilization effect is difficult to obtain, and the quality guarantee period of the packaged quick-acting rice is adversely affected.
