Embodiment approach

[0013] Another embodiment of the present invention is: put the packaged food into the sealed sterilizing pot, the pot may not contain water, after sealing, add steam through the intake valve, in this case, rely on the steam in the pot To ensure that the pressure outside the package is not lower than the pressure inside the package, there is no need to additionally inflate the pot, and it is the same as the above-mentioned embodiment during cooling.

[0014] Another cooling implementation mode: the sealed sterilizer is equipped with a water inlet valve and an outlet valve. The water inlet valve is installed under the sealed sterilizer, and the water outlet valve is installed on the top of the sealed sterilizer. Start cooling, let off part of the gas first, when the pressure is reduced to 0.5-1.5kg / cm 2 When the time comes, open the water inlet valve and press in cold water. After the water in the pot is full and the pressure is increased, then open the water outlet valve to rel...

Abstract

A method for sterilizing the packed fluid food features that after the packed food is put in a sealed sterilizer, it is heated and pressurized for a certain time and then cooled in the condition that the pressure outside the packing container is always not lower than that inside the packing container. Its advantages are no special requirement to said packing container, and innocuity to food.

Description

Technical field: [0001] The invention relates to the field of food processing, in particular to a sterilization method for packaged liquid food. Background technique: [0002] It is widely used to pack liquid food first and then reheat and sterilize it. However, during the heating and cooling process, the pressure inside the package is often higher than the pressure outside the package, so the package is easily burst by the pressure inside the package. If glass bottles are used for packaging, accidents of explosion and wounding often occur, so the prior art cannot use common packaging, which has special requirements for the compressive strength of the packaging. Invention content: [0003] The object of the present invention is to provide a sterilization method for packaged liquid food with low sterilization cost, common packaging without cracking, no antiseptic and sterilizing agent in the food, and long shelf life. [0004] The sterilization method for packaged liquid f...
