Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a prefabricated food freezing device. Background Art

[0002] Pre-prepared food, also known as pre-prepared conditioned food or pre-prepared dish, generally refers to a semi-finished or finished product made from various agricultural, livestock, poultry and aquatic products as raw materials and auxiliary materials, supplemented with seasonings and other auxiliary materials, and processed through pre-selection, modulation and other processes. It usually needs to be stored or transported under cold chain conditions for consumers or catering processors to simply heat or cook before eating. The common production process flow of frozen pre-prepared food is as follows: grading selection → cleaning → cutting → cooking → packaging → sterilization → quick freezing → packing → warehousing, among which traditional manual operation methods are widely used in the process from quick freezing to packing. For example, patent CN213542931U discloses a quick-freezing device for food processing, which carries a freezing plate of food to be frozen and then enters and exits the quick-freezing chamber under the action of a driving component to complete the quick-freezing operation. After the freezing plate is discharged from the quick-freezing chamber, the worker takes out the food and re-places and packs it. It is necessary to set up workers specifically to operate here, which is not conducive to further improving production efficiency and reducing production costs. Utility Model Content

A first conveyor belt is installed in the quick-freezing tunnel, and the head end of the first conveyor belt extends outward from the entrance of the quick-freezing tunnel to facilitate the placement of frozen food. The first conveyor belt is provided with a gathering area along the conveying direction, and the gathering area is provided with an inclined baffle. An inclined slide is arranged on one side of the first conveyor belt corresponding to the gathering area, and a second conveyor belt is arranged on the other end of the inclined slide. The end of the second conveyor belt extends outward from the exit of the quick-freezing tunnel, and the end of the second conveyor belt is connected to a telescopic slide, and a packaging box transmission device is arranged on the other side of the telescopic slide.

[0006] Optionally, the cold air vents include a plurality of cold air outlets arranged at the top of the quick-freezing tunnel and air inlets arranged on both inner side walls of the quick-freezing tunnel.

[0007] Optionally, a guide plate is provided on the inner wall of the quick-freezing tunnel corresponding to the cold air outlet.

[0008] Optionally, the refrigeration fan is installed above the quick-freezing tunnel.

[0009] Optionally, the entrance and the exit of the quick-freezing tunnel are both provided with wind curtains.

[0026] Example 1, see Figure 1-4 :

[0027] A pre-prepared food freezing device comprises a quick-freezing tunnel 1, in which a first conveyor belt 2 is installed, the head end of the first conveyor belt 2 extends outward from the entrance of the quick-freezing tunnel 1, so as to facilitate the placement of frozen food, wherein the frozen food is a pre-prepared food that has been processed and packaged, the first conveyor belt 2 is provided with a gathering area along the conveying direction, the gathering area is provided with an inclined baffle 20, baffle mounting rods 21 are installed on both sides of the first conveyor belt 2, both ends of the inclined baffle 20 are installed on the baffle mounting rod 21, and an inclined slide plate 3 is provided on one side of the first conveyor belt 2 corresponding to the gathering area, a plurality of frozen foods are conveyed to the gathering area under the action of the first conveyor belt 2, under the action of the inclined baffle 20, a plurality of frozen foods enter the inclined slide plate 3 along the inclined baffle 20, a second conveyor belt 4 is provided at the other end of the inclined slide plate 3, the end of the second conveyor belt 4 extends outward from the exit of the quick-freezing tunnel 1, the frozen food falls into the second conveyor belt 4 along the inclined slide plate 3 under the action of inertia and gravity, and the frozen food is conveyed out of the quick-freezing tunnel 1 under the action of the second conveyor belt 4.

[0028] Preferably, both the entrance and the exit of the quick-freezing tunnel 1 are provided with wind screens 10 .

[0029] The inner wall of the quick-freezing tunnel 1 is provided with a cold air outlet, which is connected to the refrigeration fan 6, and the refrigeration fan 6 is installed above the quick-freezing tunnel 1. The cold air outlet is arranged as an array air outlet, and the cold air outlet includes a plurality of cold air outlets 11 arranged at the top of the quick-freezing tunnel 1 and air inlets 12 arranged on the two inner walls of the quick-freezing tunnel 1;

[0030] Preferably, the air outlet direction of the cold air outlet 11 is vertically downward, and each cold air outlet 11 is respectively provided with two air inlets 12 on the two inner walls of the quick-freezing tunnel 1. Each cold air outlet 11 and the corresponding two air inlets 12 are arranged in the same vertical space, and the guide plates 13 are arranged on the front and rear sides of each cold air outlet. The conveying direction of the first conveyor belt 2 is perpendicular to the vertical space. The frozen food passes through several vertical spaces during the conveying direction. A stable vertical low-temperature airflow is formed in each vertical space under the action of the cold air outlet and the guide plates 13. The vertical low-temperature airflow exchanges heat with the frozen food moving horizontally along the first conveyor belt 2, thereby realizing the rapid cooling and freezing process of the frozen food.

[0031] A telescopic slide 40 is connected to the end of the second conveyor belt 4, and the telescopic slide 40 is arranged obliquely downward.

The upper part of the slider 51 is arranged as an L-shaped placement portion 52 for convenient placement of the packaging box 7. The packaging box 7 is placed on the L-shaped placement portion 52. The packaging box 7 is transmitted to the bottom of the telescopic slide 40 under the action of the packaging box transmission device 5. The frozen food falls into the packaging box 7 after passing through the second conveyor belt 4 and the telescopic slide 40. Then the packaging box transmission device 5 drives the packaging box 7 to move downward a loading distance, and the loading distance is the height of the frozen food. The subsequent frozen food continues to fall into the packaging box 7, and the above operation is repeated until the packaging box 7 is full. After the packaging box transmission device 5 removes the packaging box 7, the next packing operation can be carried out.

[0032] Preferably, since the packaging boxes 7 of different pre-prepared foods are different and the heights of the packaging boxes 7 are often different, a retractable slide plate 40 is used to facilitate the packing requirements of packaging boxes 7 of different heights.
