Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pre-prepared dishes, in particular to a biofilm fresh-keeping pre-prepared dish production line. Background Art
[0002] Pre-prepared dishes are pre-packaged dishes made from one or more edible agricultural products and their products, which are industrially pre-processed (such as mixing, pickling, rolling, kneading, shaping, stir-frying, deep-frying, baking, boiling, steaming, etc.) and can be eaten only after heating or cooking. There are many styles of pre-prepared dishes, and the raw materials are relatively complex, with high requirements for the freshness of the ingredients and storage conditions.
[0003] However, in the current production process of pre-prepared meals, in order to extend the shelf life, they must be transported through a cold chain, and preservatives and other additives are usually added. At the same time, a lot of manpower is required in the process of plating, inserting and removing plates, resulting in high labor costs. Utility Model Content

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a biofilm fresh-keeping pre-prepared food production line, characterized in that it includes a Class 100 sterile warehouse, a tunnel steamer, an ice water bath, an air knife dryer and a Class 200 sterile warehouse connected in sequence, and a hot filling packaging machine and a quantitative filling machine are arranged in the Class 100 sterile warehouse.
[0006] Furthermore, the hot filling packaging machine includes a vertical elevator, an electronic metering machine, a large bucket computer multi-head weigher, a bowl feeder and a vacuum packaging machine which are connected in sequence.
[0007] Furthermore, the large bucket computer multihead scale is also connected to a material elevator.
[0008] Furthermore, a plate placing machine, a plate inserting machine and a first-layer mounting station are arranged in sequence between the vacuum packaging machine and the tunnel steamer, and a layer mounting vehicle is arranged in the first-layer mounting station.
[0009] Furthermore, a second-layer loading and unloading station and a tray extractor are sequentially arranged between the tunnel steamer and the ice water bath, and a second conveyor line, a tray washing and drying machine and a first conveyor line are sequentially arranged between the tray extractor and the tray placing machine.
[0010] Furthermore, a third conveying line is provided between the tray extraction machine and the tray insertion machine.
[0011] Furthermore, a fourth conveying line is provided between the ice water bath machine and the air knife drying machine.
[0012] Furthermore, a sealing and bag cutting machine is installed in the Class 200 sterile warehouse.
[0013] The utility model adopts the above technical scheme, and compared with the prior art, has the following advantages: in the initial state, the cooked pre-prepared dishes are conveyed to the 100th-level aseptic warehouse, lifted by the vertical hoist to the electronic metering machine for quantitative weighing, and conveyed to the large bucket computer multi-head scale. At the same time, the material hoist conveys the auxiliary materials to the large bucket computer multi-head scale, and the cooked pre-prepared dishes and auxiliary materials are weighed again, and then enter the bowl-type feeding machine. At the same time, the quantitative filling machine fills the sauce into the bowl-type feeding machine, and finally enters the vacuum packaging machine for vacuum packaging.
[0014] The vacuum-packed pre-prepared dishes are placed on the steaming tray by the plate placing machine, and the steaming tray with the pre-prepared dishes is transferred to the plate inserting machine. The plate inserting machine inserts the steaming tray into the layer rack cart, and the layer rack cart enters the tunnel steamer to perform secondary ripening of the pre-prepared dishes. After ripening, the steamer door is automatically opened and the layer rack cart is transferred out. The plate extractor extracts the pre-prepared dishes from the steaming tray and transfers them to the ice water bath machine. At the same time, the steaming tray is placed on the second conveyor line and transferred to the plate washing and drying machine to clean and dry the steaming tray. After cleaning and drying, the steaming tray returns to the plate placing machine. The layer rack cart is transferred from the second layer rack station to the first layer rack station through the third conveyor line, waiting for the next use. After the pre-prepared dishes are cooled in the ice water bath, they are transferred to the air knife air dryer through the fourth conveyor line to air dry the water on the outer surface of the pre-prepared dishes packaging, and then transferred to the sealing and bag cutting machine in the second-level aseptic warehouse for sealing and bag cutting, and then the next process is carried out.
[0015] The present invention reduces the microbial colony in the pre-prepared dishes by performing hot filling and vacuum packaging in a Class 100 aseptic warehouse, and then performs steaming and secondary sterilization at 100-110°C in a tunnel steamer, so that the pre-prepared dishes can be circulated at room temperature without adding preservatives. At the same time, the plating, insertion, and maturation of the pre-prepared dishes, as well as the recycling of steaming plates and layer racks are fully automated, thereby reducing labor costs.
