Description

A microwave pressure sterilizer

Technical field:

The utility model relates to a sterilizing device for canned food, in particular to a microwave pressure sterilizing pot.

Background technique:

At present, canned food usually adopts high temperature and high pressure thermal sterilization and microwave sterilization methods to prolong the shelf life of food in its airtight packaging under normal temperature environment. In high temperature and high pressure sterilization, the temperature is transmitted from the surface of the food to the inside. Due to the long-term high temperature environment, most of the nutrients in the food are also destroyed, and its flavor and color will also be greatly changed. Due to its unique thermal effect, the temperature of food rapidly rises from the inside to the outside of the food under the irradiation of microwaves. The sterilization temperature is low and the time is short, which has little damage to the nutrition, flavor and color of the food. It plays an important role in sterilization. Special effects that cannot be achieved by conventional physical sterilization. However, most of the usual microwave sterilization devices are split or continuous, which occupy a large area, are inconvenient to operate, and consume high microwave energy. Especially, food packaging is easy to deform or expand, and the work efficiency is also low.

Purpose of the invention:

In order to solve the disadvantages of the existing high-temperature and high-pressure sterilization and microwave sterilization devices for canned food, the utility model provides an integrated microwave pressure sterilization pot with multi-function, good sterilization effect, no deformation and expansion of food packaging, and high work efficiency. In order to achieve the above object, the utility model adopts the following technical solutions: a microwave pressure sterilizer, which is composed of a sterilizer, a food bin, a microwave transmitter, a water spray device, a pressure device, and a temperature measuring device. It is characterized in that: the sterilizing pot is a metal container that can withstand a certain pressure. The sterilizing pot is equipped with a pot door, a temperature measuring device and a connecting flange, and the pot door is connected with the sterilizing pot through the flange; There is also a food bin in the sterilizer, and the food bin is fixed on the inner wall of the sterilizer through a steering shaft; a water spray device and a drain valve are installed on one side of the inner wall of the sterilizer, and the water spray device is connected with the water fixed on the outer wall of the sterilizer. The valves are connected; the outer wall of the sterilizer is also equipped with an intake valve and an exhaust valve communicating with it. When working, put the food to be sterilized in the food compartment, push the sterilizer to close the pot door, connect the microwave transmitter, and irradiate the food with closed microwave in multiple directions according to the needs, and wait until the temperature of the food rises to the set temperature and maintain this temperature After the set time, the microwave sterilization is over, and the microwave will not be easily lost. The canned food placed in the sterilizer, under the irradiation of microwaves, the temperature rises, the water evaporates, and the container of the packaged food will expand, but the pressure in the pot is adjusted by injecting compressed air into the sterilizer through the air inlet valve to maintain It is close to the pressure inside the packaged food container, so as to prevent its shape from being damaged and changed, and ensure that the packaged food container does not deform or expand. Open the water valve to spray cooling water to the food in the sterilizing pot through the water spray device, and at the same time open the drain valve to discharge the cooling water continuously, or after the cooling water is filled with the sterilizing pot without food and lasts for a certain period of time, then open the drain valve to drain the cooling water Discharge all at one time; after the cooling is completed, discharge all the remaining pressure in the sterilizer through the exhaust valve, and open the door to take out the food.

Due to the adoption of the above technical measures, the utility model can realize an integrated microwave pressure sterilizer with multi-function, good sterilization effect, no deformation of food packaging, no expansion, and high efficacy. It can be widely used in the technical field of food processing machinery production.
