Description

Technical Field

[0001] The utility model relates to the technical field of gelatin strip production, in particular to a full-width gelatin strip extrusion head. Background Technique

[0002] Gelatin has no fixed structure and relative molecular weight. It is degraded from the collagen part in connective tissues such as animal skin, bone, muscle membrane, and muscle charm into white or light yellow, semi-transparent, slightly shiny thin slices or powder particles; it is a colorless, odorless, non-volatile, transparent and hard amorphous substance, soluble in hot water, insoluble in cold water, but can slowly absorb water and swell and soften. Gelatin can absorb 5-10 times its weight in water. Gelatin is one of the very important natural biological macromolecular materials and has been widely used in the food, pharmaceutical and chemical industries. There is an extrusion process in the gelatin production process, where the concentrated glue solution is extruded into strips by an extruder to facilitate subsequent particle preparation. Generally, a screw extruder is used for the gelatin extrusion equipment, and an extrusion die or head is installed at the discharge end of the extruder to obtain the desired strip shape. However, in order to facilitate the shaping of the gelatin strip, the conventional extrusion head heats the gelatin strip, so when the gelatin strip is extruded, its own temperature will cause the gelatin strip to be easily deformed and not well shaped, and it is easy to stick together, which greatly affects the subsequent granulation process.

[0003] The existing technology has the following problems:

[0004] After retrieval, the existing Chinese patent publication number: CN218576943U discloses an efficient extrusion head for gelatin strip production. When this patent uses a water-cooling method to cool the gelatin strip singly during actual use, the cooling effect and efficiency on the gelatin strip are not ideal, resulting in the situation that the gelatin strip is prone to adhesion.

[0005] Therefore, we propose a full-width gelatin strip extrusion head to solve the above drawbacks. Content of the Utility Model

A cooling groove is arranged inside the cooling box. An outlet pipe and an inlet pipe are respectively arranged at the upper end and the lower end of the surface of the cooling box. A control switch is fixedly installed on the outer wall of the cooling box;

[0008] The air-cooling assembly includes an adjusting bracket, fastening bolts, a carrier, a fan, an air outlet plate, and air outlet nozzles. One end of the adjusting bracket is fixedly connected to the outer wall of the cooling box. The carrier is adjustably installed on the adjusting bracket through the fastening bolts. A fan is fixedly installed on one side surface of the carrier, and an air outlet plate is fixedly installed on the other side surface of the carrier. Air outlet nozzles are fixedly installed on the surface of the air outlet plate. The air outlet end of the fan is communicated with the air outlet plate through a pipeline.

[0009] Preferably, there are multiple air outlet nozzles, and the multiple air outlet nozzles are equidistantly distributed on the surface of the air outlet plate.

The lower end of the cooling box 4 is threadedly connected to the machine head 9, and an air-cooling component 10 is arranged below the machine head 9. A feeding port 2 is opened on the top surface of the screw extruder 1, and the screw extruder 1 is communicated with the cooling box 4 through a discharging port 3 installed at one end.

[0026] The air-cooling assembly 10 includes an adjusting bracket 101, fastening bolts 102, a carrier 103, a fan 104, an air outlet plate 105 and an air outlet nozzle 106. One end of the adjusting bracket 101 is fixedly connected to the outer wall of the cooling tank 4. The carrier 103 is adjustably mounted on the adjusting bracket 101 through the fastening bolts 102.

The air outlet nozzle 106 is fixedly mounted on the surface of the air outlet plate 105. The air outlet end of the fan 104 is communicated with the air outlet plate 105 through a pipeline.

[0027] During use, the screw extruder 1 injects the gelatin concentrate into the cooling tank 4 under pressure and finally extrudes it from the machine head 9. During this process, the water inlet pipe 6 is connected to an external cooling water source, and the cooling water source can be continuously injected into the cooling tank 5. The heated water after heat exchange is discharged from the water outlet pipe 7. The flowing cooling water can play a role in water-cooling during the extrusion process of the gelatin strip. After the gelatin strip is extruded from the machine head 9, through the air-cooling assembly 10, the gelatin strip extruded from the machine head 9 can be cooled and temperature-reduced by secondary air-cooling, further improving the cooling and shaping effect and efficiency of the gelatin strip, preventing the gelatin strip from sticking. Compared with the method of using water-cooling alone to cool and temperature-reduce the gelatin strip, the cooling effect on the gelatin strip is better, and the cooling efficiency is more efficient. Secondly, by setting the machine head 9 threadedly connected to the cooling tank 4, it is beneficial to maintain the machine head 9, and the operation is convenient, labor-saving, and has strong practicability and is worthy of promotion.

[0028] In this embodiment: There are multiple air outlet nozzles 106, and the multiple air outlet nozzles 106 are evenly distributed on the surface of the air outlet plate 105.

[0029] Specifically, improve the secondary air-cooling effect and efficiency of the extruded gelatin strip.

[0030] In this embodiment: The control switch 8 is electrically connected to the screw extruder 1 and the fan 104 through wires.

[0035] Specifically, it is convenient to flexibly adjust the distance between multiple groups of air-cooling components 10 and the gelatin strips extruded from the machine head 9 according to actual installation requirements, so as to meet the air-cooling effect and requirements.

[0036] In this embodiment: The diameter of the cooling tank 5 is smaller than the diameter of the cooling box 4.

[0037] Specifically, the cooling tank 5 can be opened in the cooling box 4.

[0038] In this embodiment: The control switch 8 is of an existing structure, and the control circuit can be realized by simple programming by those skilled in the art, which belongs to the common knowledge in this field. Only its use is described without modification, so the control method and circuit connection will not be described in detail.

[0039] Working principle: During use, the screw extruder 1 injects the gelatin concentrate into the cooling box 4 through pressure and finally extrudes it from the machine head 9. During this process, the water inlet pipe 6 is connected to an external cooling water source, and the cooling water can be continuously injected into the cooling tank 5, while the hot water after heat exchange is discharged from the water outlet pipe 7, which can play a role in water cooling during the extrusion process of the gelatin strips. After the gelatin strips are extruded from the machine head 9, through the air-cooling components 10, the gelatin strips extruded from the machine head 9 can be cooled and cooled down for the second time by air, further improving the cooling and shaping effect and efficiency of the gelatin strips, preventing the gelatin strips from sticking. Compared with the method of using water cooling alone to cool and cool down the gelatin strips, the cooling effect on the gelatin strips is better, and the cooling efficiency is more efficient. Secondly, by setting the machine head 9 threadedly connected to the cooling box 4, it is beneficial to maintain the machine head 9, and the operation is convenient, labor-saving and has strong practicability, which is worthy of promotion.
