Description

Technical Field

[0001] The utility model relates to the technical field of pre-prepared food processing equipment, in particular to a pre-prepared food sealing and packaging machine. Background Art

[0002] Pre-prepared meals, also known as pre-prepared conditioned foods, generally refer to semi-finished or finished products that are made from various agricultural, livestock, poultry, and aquatic products as raw materials and auxiliary materials, along with seasonings and other auxiliary materials, and are processed through pre-selection, modulation and other processes. Usually, pre-prepared meals need to be stored or transported under cold chain conditions for consumers or processors in the catering industry to simply heat or cook before consumption.

[0003] During the processing of pre-prepared meals, in order to increase the shelf life of the pre-prepared meals, the pre-prepared meals are usually vacuumed, and then the packaging bags of the pre-prepared meals are heated by manually pressing the operating lever to push the heat conduction plate. At this time, the packaging bags melt when heated and stick together, thereby sealing the pre-prepared meals.

[0004] The above method requires many manual steps when sealing the pre-prepared food. On the one hand, the heat conduction plate needs to be manually pressed to perform heat sealing. On the other hand, the pre-prepared food bag needs to be manually supported to prevent it from shifting, thereby increasing the labor of the processing personnel.

[0005] Therefore, it is necessary to design a pre-prepared meal sealing and packaging machine to solve the above-mentioned problems. Utility Model Content
