Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of oil film removal, and particularly relates to a method for removing the oil film of fish maw. Background Art
[0002] When making fish maw, it is necessary to remove the oil film on the surface of the fish bladder. There is a thick layer of oil film attached to the outer surface of the fish bladder. At present, the oil film is generally removed manually. The oil film is removed by methods such as rinsing with clean water and manual rubbing, but the manual operation efficiency is low, and there may be a problem that the oil film removal is not thorough, which affects the later production of fish maw.
[0003] To ensure the good quality of fish maw and improve production efficiency, it is necessary to remove the oil film on the fish bladder more quickly and cleanly. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide a method for removing the oil film of fish maw in view of the above-mentioned technical deficiencies, which solves the problem of low efficiency of removing the oil film from the fish bladder in the prior art.
[0005] The technical solution adopted by the present invention is as follows: A method for removing the oil film of fish maw is provided, including the following steps:
[0006] S1, flatten: Flatten the fish bladder, with the oil film on the outside of the fish bladder.
[0007] S2, quick-freeze: Quick-freeze and shape the fish bladder.
[0008] S3, peel: After the fish bladder is quick-frozen and shaped, peel off the oil film on the surface of the fish bladder by friction.
[0009] Further optimizing the technical solution, in step S2, the flattened fish bladder enters the quick-freezer for quick-freezing.
[0010] Further optimizing the technical solution, in step S3, use a friction device to wipe off the oil film on the surface of the fish bladder by friction.
[0011] Further optimizing the technical solution, the friction device is a grinding rod or sandpaper.
[0012] Further optimizing the technical solution, in step S3, first fix the quick-frozen and shaped fish bladder with a clamp, then wipe off the oil film on one side of the fish bladder by friction, and turn the fish bladder over to remove the oil film on the other side.
[0013] Further optimizing the technical solution, the clamp clamps and fixes the fish bladder from both sides of the flattened fish bladder.
[0014] The beneficial effects of the present invention are as follows:
[0015] 1. After the fish swim bladder is flattened and quickly frozen and shaped, the oil film can be more completely presented on the outside, which is convenient for rapid removal through friction, and the removal of the oil film is more efficient.
[0016] 2. By means of friction, the oil on the surface of the fish swim bladder can be rubbed off together with the oil film (usually the oil mass is connected to the oil film).
[0017] 3. Friction cleaning requires no additives, is faster to clean, and is more environmentally friendly and healthy. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0022] To make the drawings concise, only the parts related to the invention are schematically shown in each figure, and they do not represent their actual structures as products. In addition, to make the drawings concise and easy to understand, in some figures, parts with the same structure or function are only schematically shown for one of them, or only one of them is marked. In this article, "one" not only means "only this one", but also can mean "more than one" situation, and "several" includes "two" and "more than two".
[0023] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0024] In addition, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.
[0025] As Figure 1-2 shown, a method for removing the oil film of fish glue includes the following steps:
[0026] S1. Flattening, flatten the fish swim bladder, and the oil film is located outside the fish swim bladder;
[0027] S2. Quick freezing: quickly freeze and shape the swim bladder.
[0028] S3. Stripping: for the swim bladder after quick freezing and shaping, strip the oil film on the surface of the swim bladder by friction.
[0029] During use, the swim bladder is laid flat and then quickly frozen to shape it. The oil film is on the outside. The swim bladder after quick freezing and shaping is in a fixed form, which is convenient for fixation. It will not deform, shrink, or fold during friction, etc., which is convenient for quickly removing and stripping all the external oil films and improving the efficiency of removing the oil film. Laying the swim bladder flat means unfolding it smoothly in its complete state, exposing the fish oil on the outside. Figure 2 It is only used to show the flattened states of various swim bladders to facilitate understanding of the state of the swim bladder, and there is no restrictive understanding. Those skilled in the art can know the flattened state.
[0030] Further, in step S2, the flattened swim bladder enters the quick freezer 2 for quick freezing.
[0031] During use, when the swim bladder is quickly frozen, the swim bladder can be placed in the quick freezer 2 to achieve quick shaping. The quick freezer 2 can adopt a brine double-effect single quick freezer 2.
[0032] Further, in step S3, use the friction device 3 to wipe off the oil film on the surface of the swim bladder by friction. The friction device 3 is a grinding rod or sandpaper.
[0033] During use, when removing the oil film by friction, friction devices 3 such as grinding rods and sandpapers can be used to enhance the friction force and carrying capacity to wipe off and strip the oil film. It can be operated by hand or with the help of existing reciprocating motion mechanical equipment to drive the friction device 3 to move.
[0034] Further, in step S3, first use the fixture 4 to fix the swim bladder after quick freezing and shaping, and then use friction to wipe off the oil film on one side of the swim bladder. After the swim bladder is turned over, remove the oil film on the other side.
[0035] During use, first use the fixture 4 to clamp and fix the shaped swim bladder. The friction device 3 strips the oil film on the surface of the swim bladder, then turn the swim bladder over, clamp and fix it again, and use the friction device 3 to remove the oil film on the other side to complete the removal of the oil film from one swim bladder.
[0036] Further, the fixture 4 clamps and fixes the swim bladder from both sides of the flattened swim bladder.
[0037] During use, the fixture 4 can adopt two relatively moving clamping plates to clamp and fix the flattened swim bladder from both sides, which is convenient for wiping off the fish oil exposed above. The fixation of the fixture 4 can prevent the swim bladder from shaking significantly. When in a clamped and stuck state, the swim bladder is stable and does not move, so the operation during friction is more stable.
[0038] It is understood that the present invention is described by way of some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present invention. Additionally, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
