Description

Technical Field

[0001] The utility model relates to the technical field of preparation of collagen artificial casings, in particular to a collagen casing processing device. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] In the drying process of collagen casing production, sodium carbonate or sodium bicarbonate solution is generally sprayed to adjust the pH value of the collagen casing to change the state of the collagen fibers in the collagen casing. However, this method causes a large amount of sodium salt to be mixed into the collagen casing. Since the ash content directly affects the functionality of protein in absorbing oil and water, the mechanical properties of the collagen casing are reduced.

[0004] The collagen casing coming out of the molding machine is relatively soft. Even after neutralization and shaping, it is easy to be stretched during the drying process. Once the collagen casing is stretched excessively, the thickness of the collagen casing film will be uneven, or even holes will appear, affecting the quality of the casing. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the embodiments of the present utility model is to provide a collagen casing processing device.

[0006] In order to achieve the above purpose, the embodiment of the utility model provides the following technical solutions:

[0007] A collagen casing processing device, comprising:

[0008] Nitrogen gas source, ammonia gas control device, molding machine, ammonia box and liquid nitrogen freezer;

[0009] The front end of the ammonia gas control device is connected to the ammonia gas source through a pipeline;

[0010] The forming machine is connected to an ammonia box. The forming machine is used to process collagen into tubular casings. The ammonia box is used to receive the casings produced by the forming machine and shape the casings.

[0011] The ammonia gas control device includes a first ammonia gas control device and a second ammonia gas control device. The first ammonia gas control device passes through the forming machine through a pipeline and is connected to the inside of the casing; the second ammonia gas control device is connected to the inside of the ammonia box through a pipeline;

[0012] The ammonia box is also connected to a liquid nitrogen freezer, through which the casings enter the liquid nitrogen freezer, which is connected to a liquid nitrogen tank for rapid freezing of the casings.

[0013] The utility model provides two sets of ammonia gas control devices to respectively pass ammonia into the inside of the tubular casing and the ammonia box, so as to quickly shape the casing without mixing ash, thereby improving the mechanical properties of the casing. At the same time, since the collagen casing is relatively soft and can be easily stretched during the drying process, the ammonia is quickly frozen by a liquid nitrogen freezer to prevent the casing from stretching and deformation, thereby improving the uniformity of the casing.

[0014] In some embodiments, the first ammonia gas control device is connected to a pressure sensor, which is disposed inside the casing to detect the air pressure inside the casing tube and adjust the opening degree of the electric control gas valve according to the detection data of the pressure sensor.

[0015] As ammonia reacts with the acidic substances in the casing and is continuously absorbed by the casing, the air pressure in the casing tube decreases. Therefore, the air pressure sensor detects the air pressure in the casing tube and adjusts the opening and closing degree according to the data detected by the air pressure sensor to control the flow rate of ammonia.

[0016] In some embodiments, the second ammonia gas control device is connected to an ammonia concentration sensor, which is disposed in the ammonia box to detect the concentration of ammonia in the ammonia box and adjust the opening degree of the gas valve according to the detection data of the ammonia concentration sensor.

[0017] In some embodiments, rollers are evenly arranged in the ammonia box for conveying the casings.

[0018] In some embodiments, a conveyor belt is provided in the liquid nitrogen freezing box, and the conveyor belt is a conveyor mesh belt.

[0019] In some embodiments, a drying device is connected to the rear of the liquid nitrogen freezer to dry the casings. The casings are quickly frozen in the liquid nitrogen freezer and then directly dried to prevent the casings from being stretched and deformed during the drying process.

[0020] In some embodiments, the liquid nitrogen freezer is connected to the liquid nitrogen tank via a pipeline, and a nitrogen valve is provided between the liquid nitrogen freezer and the liquid nitrogen tank.

[0021] In some embodiments, a nozzle is provided in the liquid nitrogen freezing box, and the nozzle is connected to the nitrogen valve through a pipeline.

[0022] In some embodiments, the ammonia tank is configured as a box or a tubular structure.

[0023] One or more technical solutions provided in the embodiments of the present utility model have at least the following technical effects or advantages:

[0024] 1. After the quick freezing in the liquid nitrogen box, part of the water in the collagen casing is analyzed on the surface, which is convenient for rapid drying in the later stage; at the same time, the temperature of the collagen casing is reduced, and the collagen casing can be prevented from becoming soft, sticky or deteriorating due to excessively rapid temperature rise during the drying process, thereby improving the uniformity of the casing and improving the quality of the casing; at the same time, the pH of the casing is adjusted by internal and external ammonia to shape the casing, and the ammonia is volatilized by heat during the later drying, and the ash content of the collagen casing is not increased, thereby improving the mechanical properties of the casing.

[0025] 2. The device of the utility model uses ammonia to shape the inside and outside of the casing, replacing the spraying of sodium carbonate or sodium bicarbonate solution, thereby reducing the added water, saving subsequent drying time, reducing the water production inside the drying line, reducing the production dehumidification energy consumption, and improving production efficiency.

[0030] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0031] As introduced in the background technology, in the prior art, the collagen casing is relatively soft and is easily stretched during the drying process, resulting in uneven thickness of the collagen casing film. In order to solve the above technical problems, the utility model proposes a collagen casing processing device.

[0032] like Figure 1 As shown, an embodiment of the utility model describes a collagen casing processing device, including: a nitrogen gas source, an ammonia gas control device, a molding machine 4, an ammonia gas box 5 and a liquid nitrogen freezer 6;

[0033] The forming machine 4 is connected to the ammonia box 5, and the collagen is passed through the forming machine 4 to obtain a tubular casing, which is extruded from the forming machine outlet 42. A hollow tube 41 is provided in the forming machine 4, and the front end of the hollow tube 41 is connected to the compressed air control device 1 and the first air control device 2. The front end of the compressed air control device 1 is connected to an air pump, and the air pump passes compressed air into the interior of the tubular collagen casing 11 through the compressed air control device 1 at a preset air flow rate, so that the interior of the collagen casing 11 maintains a certain air pressure; the ammonia box 5 is used to receive and convey the casing produced by the forming machine 4, and the ammonia box 5 is also used to shape the casing.

[0034] Since the casing extrusion structure of the forming machine and other structures are irrelevant to the problem solved by the present invention, they will not be described in detail here and the existing technology can be used.

[0035] Optionally, according to the flow direction of the gas, the front ends of the two ammonia gas control devices are connected to the ammonia gas source through pipelines, wherein the first gas control device 2 is connected to the hollow tube 41 of the molding machine through a pipeline, and the hollow tube passes through the molding machine 4 and is connected to the inside of the collagen casing 11, and the ammonia in the first ammonia gas control device 2 is transported to the inside of the casing tube. The second gas control device 3 is connected to the ammonia box 5 through a pipeline, and the ammonia in the second gas control device 3 is transported to the ammonia box 5, and the casing tube extruded from the molding machine outlet 42 enters the ammonia box 5 for shaping.

[0036] After being shaped in the ammonia box 5, the collagen casing 11 changes from a transparent colloidal color to white, and the casing pH value also increases from the original 2.6 to about 4.8 (isoelectric point of collagen). The state of the protein fiber in the collagen casing 11 changes due to its pH value, and its state also changes accordingly, and the fiber becomes more resilient, thereby improving the mechanical properties and flexibility of the collagen, and the collagen casing becomes stronger; the obtained casing improves the bonding degree between the casing and the meat filling, improves the casing's resistance to frying, baking and boiling, and reduces the phenomenon of casing breakage during filling, falling off the furnace and a large number of defective products.

[0037] Optionally, a liquid nitrogen freezer 6 is connected to the rear of the ammonia box 5, and the liquid nitrogen freezer 6 is connected to a liquid nitrogen tank 8 through a liquid nitrogen gas control device 7. The casings are shaped and thickened by the ammonia box 5 and then enter the liquid nitrogen freezer 6 to be quickly frozen.

[0038] Optionally, a nitrogen valve is provided between the liquid nitrogen freezer 6 and the liquid nitrogen tank 8, a nitrogen nozzle 63 is provided at the top and bottom of the liquid nitrogen freezer 6, the liquid nitrogen tank 8, the nitrogen valve and the nitrogen nozzle 63 of the liquid nitrogen freezer 6 are connected in sequence through pipelines, a conveyor mesh belt 62 is provided along the liquid nitrogen freezer 6, the conveyor mesh belt 62 conveys the casings, and because the conveyor mesh belt 62 is in a grid shape, the casings can be exposed to low-temperature nitrogen from top to bottom for rapid and uniform freezing.

[0039] Specifically, the liquid nitrogen gas control device 7 can spray out nitrogen at a preset flow rate according to the conveying speed of the conveyor mesh belt 62, or a temperature sensor 61 can be set in the liquid nitrogen freezer 6, and the temperature sensor 61 is used to detect the temperature in the liquid nitrogen freezer 6. The temperature sensor 61 is connected to the liquid nitrogen gas control device 7, and the liquid nitrogen gas control device 7 adjusts the nitrogen flow rate according to the detected temperature.

[0040] Optionally, the ammonia gas control device includes an air valve, which is an electric control air valve. The electric control air valve and the sensor are electrically connected to the controller. All controllers of the utility model are existing controllers. Among them, the first air control device 2 is connected to the air pressure sensor 43, which is arranged in the hollow tube 41 of the forming machine, that is, inside the collagen casing 11. The air pressure sensor 43 detects the air pressure in the casing tube and transmits the obtained air pressure data to the controller. The controller adjusts the opening degree of the first electric control air valve according to the data uploaded by the air pressure sensor 43, and replenishes the ammonia consumed by the reaction in time. The second air control device 3 is connected to the ammonia concentration sensor 52, which is arranged in the ammonia box 5. The ammonia concentration sensor 52 detects the concentration of ammonia in the ammonia box 5, and uploads the obtained ammonia concentration data to the controller. The controller adjusts the opening degree of the second electric control air valve according to the detection data of the ammonia concentration sensor 52, and replenishes the ammonia consumed by the reaction in time.

[0041] Optionally, the ammonia box 5 can be set as a box or a tubular structure. Existing technology can be used here. It does not need to be completely sealed here, so as to achieve a relatively stable ammonia concentration in the ammonia box 5. A plurality of evenly arranged rollers 51 are provided in the ammonia box 5, and the casings are conveyed by the rollers 51.

[0042] Optionally, a drying device 10 is connected to the rear of the liquid nitrogen freezing box 6, and the casings quickly frozen by nitrogen enter the drying device 10 for drying.

[0043] After quick freezing in a liquid nitrogen box, on the one hand, part of the water in the collagen casing 11 is separated out and attached to the surface of the casing, which is convenient for rapid drying later; at the same time, the temperature of the collagen casing 11 is reduced, avoiding the collagen casing from becoming soft, sticky or deteriorating due to excessive temperature rise during the drying process, improving the strength of the casing during the drying process, reducing the phenomenon of uneven thickness of the collagen casing 11 caused by the casing being stretched during the drying process, improving the uniformity of the casing, and further improving the quality of the casing.

[0044] Working principle: The utility model is provided with an ammonia gas control device. The first gas control device 2 passes ammonia into the hollow tube 41 of the molding machine 4 through a pipeline, and the ammonia enters the inside of the casing tube through the hollow tube 41. The second gas control device 3 injects ammonia into the ammonia box 5 through a pipeline. The air pressure sensor 43 and the ammonia concentration sensor 52 detect the pressure in the casing tube and the ammonia concentration in the ammonia box respectively, and adjust the valve opening according to the detected pressure and concentration, and adjust the output of the two-way ammonia. The set pressure is reached in the collagen casing 11, and the set concentration is reached in the ammonia box 5, ensuring that a certain ammonia concentration is always maintained inside and outside the casing, so that the collagen casing 11 reacts with ammonia to shape.

[0045] At the same time, the casing is transported by the roller 51 through the outlet of the ammonia box 5 at a uniform speed, and then enters the liquid nitrogen freezer 6. The conveyor mesh belt 62 in the liquid nitrogen freezer 6 continues to transport, and the nitrogen valve is opened. Low-temperature nitrogen is sprayed onto the casing through the nitrogen nozzle 63 of the liquid nitrogen freezer 6. The casing is quickly cooled by nitrogen on the mesh belt and transported to the outlet of the liquid nitrogen freezer 6, and directly enters the drying device 10 for drying.

[0046] The device of the utility model replaces the sodium carbonate or sodium bicarbonate solution spraying device, does not need to spray solution, saves drying time, reduces the water production inside the drying line, reduces the energy consumption of production dehumidification, and improves production efficiency. After the later drying, the ammonia salt decomposes and volatilizes at high temperature, and the ash content of the collagen casing does not increase, which further improves the mechanical strength and flexibility of the casing; at the same time, nitrogen box shaping and nitrogen freezing reduce the drying time of the casing, reduce the amount of high-temperature denaturation of collagen in the casing during the drying process, and improve the quality of the casing.

[0047] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
