A process for the production of easy peel cellulose casings

Abstract

This invention discloses a production process for easy-peeling cellulose casings. It employs a spray nozzle to spray an anti-sticking agent onto the inner wall of the casing, forming an anti-stick coating to improve the peelability of the cellulose casing. Furthermore, by controlling the air supply flow rate during the anti-sticking agent spraying process, the speed at which the casing moves away from the spray nozzle and the number of spray nozzles for the anti-sticking agent can be simultaneously adjusted, ensuring that the number of spray nozzles matches the speed at which the casing moves away from the spray nozzle. This improves the efficiency and effectiveness of the anti-sticking agent spraying process on the inner wall of the casing.

Description

Technical Field

[0001] This invention relates to a production process for easily peelable cellulose casings. Background Technology

[0002] Cellulose casings are a common type of casing used in the food processing industry. They are generally made from natural fibers. Cellulose casings have excellent toughness and breathability. They are also stable under rapid heat treatment and can be smoked even in moist conditions.

[0003] To improve the peelability of cellulose casings, an anti-sticking agent needs to be sprayed onto the inner wall of the casing to form an anti-sticking coating, thereby improving the peelability of the cellulose casing.

[0004] Generally, an anti-sticking agent is sprayed onto the inner wall of sausage casings using a spray nozzle, but the control of this anti-sticking agent spraying onto the inner wall of sausage casings needs improvement. Summary of the Invention

[0005] The purpose of this invention is to provide a production process for easy-peeling cellulose casings, which involves spraying an anti-sticking agent onto the inner wall of the casing using a spraying pipe to form an anti-sticking coating on the inner wall of the casing, thereby improving the peelability of the cellulose casing.

[0006] The first end of the spray pipe is provided with: a liquid spraying port, an air spraying port, and a sealing mechanism for sealing the liquid spraying port; the sealing mechanism is driven by the air source of the liquid spraying port, and the number of liquid spraying ports sealed by the sealing mechanism is adjusted by the air supply flow rate of the air source.

[0007] The process of spraying an anti-sticking agent onto the inner wall of sausage casings using a spray nozzle includes the following steps:

[0008] The sausage casing is fitted onto the spray tube from the first end, and the end of the casing that is exposed outside the first end of the spray tube is sealed; then, air is sprayed onto the casing through the air nozzle, causing the casing to expand and move away from the spray tube; and an anti-sticking agent is sprayed onto the inner wall of the casing through the liquid spray nozzle, forming an anti-sticking coating on the inner wall of the casing.

[0009] Furthermore, by controlling the air supply flow rate, the speed at which the casing moves away from the spray pipe and the number of spray nozzles for applying the anti-sticking agent to the inner wall of the casing can be adjusted simultaneously.

[0010] By increasing the air supply flow rate, the speed at which the casing moves away from the spray pipe can be increased, and the number of spray nozzles for spraying anti-sticking agent onto the inner wall of the casing can be increased.

[0011] By reducing the air supply flow rate, the speed at which the casing moves away from the spray nozzle is reduced, as is the number of spray nozzles for applying anti-sticking agent to the inner wall of the casing.

[0012] For details on the specific structure of the spray pipe and the sealing mechanism of the present invention, as well as the cooperation scheme between the two, please refer to the specific embodiments.

[0013] The advantages and beneficial effects of this invention are as follows: It provides a production process for easily peelable cellulose casings, which improves the peelability of cellulose casings by spraying an anti-sticking agent onto the inner wall of the casing to form an anti-sticking coating; and it can simultaneously adjust the speed at which the casing moves away from the spraying pipe and the number of spray nozzles for spraying the anti-sticking agent onto the inner wall of the casing by controlling the air supply flow rate of the air source (air supply pipe) when spraying the anti-sticking agent onto the inner wall of the casing, so that the number of spray nozzles for spraying the anti-sticking agent onto the inner wall of the casing is adapted to the speed at which the casing moves away from the spraying pipe; thereby improving the efficiency and effectiveness of spraying the anti-sticking agent onto the inner wall of the casing.

[0017] The specific technical solution of this invention is as follows:

[0018] like Figure 1 and Figure 2 As shown, the present invention provides a production process for easy-peel cellulose casings, which uses a spraying pipe 1 to spray an anti-sticking agent onto the inner wall of the casing, forming an anti-sticking coating on the inner wall of the casing, thereby improving the peelability of the cellulose casing.

Figure 1 and Figure 2 The gas supply pipe is not shown in the diagram, as is the liquid supply pipe connected to the infusion channel 14. Figure 1 and Figure 2 (The supply pipe is not shown in the image).

[0021] The end cap 2 includes: a circular end plate 21 located on the right side of the spray pipe 1 and coaxial with the spray pipe 1; a cylindrical sliding column 22 extending to the left from the center of the left side wall of the end plate 21 and extending into the mounting hole 11; and a cylindrical cover 23 extending to the left from the edge of the end plate 21 and fitted onto the left end of the spray pipe 1; the sliding column 22 and the cover 23 are both coaxial with the end plate 21; the end plate 21 is provided with a plurality of air jets 24, which are located around the sliding column 22 and are evenly distributed along the circumference of the end plate 21; an air supply hole 25 is opened at the center of the left end face of the sliding column 22, and the air supply hole 25 is... The sliding column 22 is coaxial; the left end of the air supply hole 25 is connected to the right end of the air supply channel 13, and the right end of the air supply hole 25 extends to the right end of the sliding column 22; multiple air vents 26 are provided on the outer peripheral surface of the right end of the sliding column 22, and these multiple air vents 26 are connected to the air supply hole 25, and these multiple air vents 26 are evenly distributed along the circumferential direction of the outer peripheral surface of the sliding column 22; these multiple air vents 26 are located on the right side of the spray pipe 1, and these multiple air vents 26 are also connected to multiple air jets 24 on the end plate 21; the cylindrical cover 23 is slidably engaged with the outer peripheral surface of the left end of the spray pipe 1, and the cylindrical cover 23 covers the multiple sets of liquid spraying nozzles 12 on the outer peripheral wall of the left end of the spray pipe 1;

[0022] The spring 3 is disposed in the mounting hole 11 and is fitted onto the slide post 22; an inner convex ring 15 extends radially inward from the right end of the mounting hole 11 and is fixedly connected to the right end of the spring 3. The inner convex ring 15 is coaxial with the mounting hole 11, and the inner ring of the inner convex ring 15 slides with the outer peripheral wall of the slide post 22; an outer convex ring 27 extends radially outward from the left end of the slide post 22 and is fixedly connected to the left end of the spring 3. The outer convex ring 27 is coaxial with the slide post 22, and the outer ring of the outer convex ring 27 slides with the inner peripheral wall of the mounting hole 11; the spring 3 is always compressed between the inner convex ring 15 and the outer convex ring 27.

[0023] The process of spraying an anti-sticking agent onto the inner wall of the sausage casing using spray tube 1 includes the following steps:

[0024] The sausage casing is fitted onto the spray tube 1 from the left end, and the end of the sausage casing that is exposed on the left side of the spray tube 1 is sealed.

[0025] Then, the air supply pipe supplies air to the air jet 24 on the end plate 21 through the air supply channel 13, air supply hole 25, and air vent 26; and the liquid supply pipe supplies anti-sticking agent to the liquid spraying port 12 on the outer peripheral surface of the right end of the spraying pipe 1 through the liquid supply channel 14; the air jet 24 sprays air onto the casing, causing the casing to expand and move away from the spraying pipe 1; and the gas output from the air vent 26 exerts a rightward force on the end plate 21, pushing the end cap 2 to the right, so that part of the liquid spraying port 12 on the outer peripheral surface of the right end of the spraying pipe 1 is exposed out of the casing 23; the liquid spraying port 12 exposed out of the casing 23 sprays anti-sticking agent onto the inner wall of the casing, forming an anti-sticking coating on the inner wall of the casing;

[0026] Furthermore, by controlling the air supply flow rate through the air supply pipe, the speed at which the casing moves away from the spray pipe 1 and the number of spray nozzles 12 for spraying the anti-sticking agent onto the inner wall of the casing are adjusted synchronously.

[0027] When the air supply flow rate of the air supply pipe increases, the air output flow rate of the vent 26 and the air jet 24 increases; therefore, the air jet flow rate of the air jet 24 towards the casing increases, causing the casing to move away from the spray pipe 1 at a faster speed; and the gas output from the vent 26 exerts a greater rightward force on the end plate 21, pushing the end cap 2 further to the right, increasing the number of spray nozzles 12 exposed on the outer circumference of the right end of the spray pipe 1 through the sleeve 23, that is, increasing the number of spray nozzles 12 for spraying anti-sticking agent onto the inner wall of the casing; thus, by increasing the air supply flow rate of the air supply pipe, the speed at which the casing moves away from the spray pipe 1 is increased, and the number of spray nozzles 12 for spraying anti-sticking agent onto the inner wall of the casing is increased.

[0028] When the air supply flow rate of the air supply pipe decreases, the air output flow rate of the vent 26 and the air jet 24 decreases; therefore, the air jet flow rate of the air jet 24 towards the casing decreases, causing the casing to move away from the spray pipe 1 at a slower speed; and the force exerted by the gas output from the vent 26 on the end plate 21 to the right decreases, and the spring 3 pulls the end cap 2 back to the left through the sliding column 22, reducing the number of spray nozzles 12 exposed on the outer circumference of the right end of the spray pipe 1 by the sleeve 23, that is, reducing the number of spray nozzles 12 spraying anti-sticking agent onto the inner wall of the casing; that is, by reducing the air supply flow rate of the air supply pipe, the speed at which the casing moves away from the spray pipe 1 is reduced, and the number of spray nozzles 12 spraying anti-sticking agent onto the inner wall of the casing is reduced.

[0029] As can be seen from the above, the production process of the easy-peel cellulose casing of the present invention improves the peelability of the cellulose casing by spraying an anti-sticking agent onto the inner wall of the casing to form an anti-sticking coating; and when spraying the anti-sticking agent onto the inner wall of the casing, the speed at which the casing moves away from the spraying pipe 1 and the number of spray nozzles 12 for spraying the anti-sticking agent onto the inner wall of the casing can be adjusted simultaneously by controlling the air supply flow rate of the air supply pipe, so that the number of spray nozzles 12 for spraying the anti-sticking agent onto the inner wall of the casing is adapted to the speed at which the casing moves away from the spraying pipe 1; thereby improving the efficiency and effect of spraying the anti-sticking agent onto the inner wall of the casing.

[0030] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
