Food filling sealing device with steam sterilization function

Abstract

The invention discloses a food filling sealing device with a steam sterilization function. The food filling sealing device comprises a cap screwing mechanism and a bottle cap storage cylinder, whereina conveying belt for conveying packaging bottles is arranged below the cap screwing mechanism, the conveying belt can pass through the lower portion of the cap screwing mechanism without obstructionwith the packaging bottles after cap screwing is finished, and meanwhile, a clamping mechanism is arranged at the position, corresponding to the cap screwing mechanism, of the conveying belt. According to the food filling sealing device with the steam sterilization function, the automatic cap sealing operation of canned food can be realized, meanwhile, before the capping operation is carried out,steam heating and disinfection of the food can be realized by utilizing a telescopic needle tube which can be connected with a steam generating device, and meanwhile, the internal air is reduced afterthe sealed canned food is cooled by utilizing the characteristics of thermal expansion and chilling contraction, so that the shelf life of the food is prolonged; and a high-concentration disinfectingand sealing mechanism is adopted, so that the heating time of the canned food in the actual packaging process is shortened, the heating frequency of the canned food in the actual packaging process, and the packaging cost is reduced.

Description

technical field [0001] The invention relates to the field of food processing machinery, in particular to a food filling and sealing device with steam sterilization function. Background technique [0002] Canning is a method of storing food; food is first processed at high temperature, then put into tin cans, and vacuum-treated; canned food is sterilized at high temperature, vacuum-packed, without adding preservatives, and the food storage period is longer long. [0003] In the screen filling process, before a large amount of food to be filled is produced in the same batch, the processed food needs to be heat-treated, and then filled, generally cooled after heat treatment, and then continuously filled by the machine. However, in the long-term practical process of these filling equipment and production lines, it is found that there is a certain amount of air in the food filled after cooling, resulting in a shorter shelf life of the filled food. Therefore came out the vacuum ...

Problems solved by technology

However, in the process of long-term practical use of these filling equipment and production lines, it is found that there is a certain amount of air inside the cooled and filled food, resulting in a short shelf life of the filled food.

Therefore, vacuum filling and sealing equipment has come out, but this equipment has a complicated structure and low cost, and is not suitable for promotion and use in small enterprises.
