Description

[Technical Field]

[0001] This utility model relates to the field of aquatic product processing technology, specifically, a dehairing device for shrimp processing. [Background Technology]

[0002] Shrimp processing is a crucial step in aquatic product processing. Traditional shrimp processing often struggles to completely remove shrimp whiskers and broken heads, affecting product quality and appearance. Currently, most shrimp processing equipment on the market focuses on washing, steaming, and drying, while equipment for de-hairing is relatively scarce and inefficient. With consumers increasingly demanding higher food quality, efficient and thorough shrimp de-hairing equipment has become an urgent need in the industry.

[0003] Existing shrimp de-hairing technologies mainly include two methods: manual sorting and mechanical screening. While manual sorting can thoroughly remove shrimp whiskers and heads, it is inefficient, labor-intensive, and costly. Mechanical screening typically uses vibrating screens or airflow separation, but vibrating screens can easily damage shrimp, while airflow separation is unstable and difficult to completely remove shrimp whiskers and heads.

[0004] Manual sorting is inefficient and costly; mechanical screening using vibrating screens can easily damage shrimp and result in unstable airflow separation, making it difficult to meet the production requirements for high-quality shrimp. [Utility Model Content]

[0005] Therefore, the technical problem to be solved by this utility model is to provide a dehairing device for a shrimp processing boat, which can efficiently and thoroughly remove shrimp whiskers and broken shrimp heads during the shrimp processing process, while avoiding damage to the shrimp and improving product quality and production efficiency.

[0006] To achieve the aforementioned novel objective, the technical solution adopted in this utility model embodiment is: a dehairing device for a shrimp processing boat, comprising a first conveyor belt and a shrimp whisker removal device; the shrimp whisker removal device comprises a blower array, a suction hood, a suction pipe, a first suction fan, and a shrimp whisker collection bin;

[0007] The blower array is positioned below the first conveyor belt, spanning the entire width of the first conveyor belt, and is used to blow the shrimp whiskers on the first conveyor belt to float.

[0008] The suction hood is positioned above the first conveyor belt and corresponding to the position of the blower array, and is used to collect the shrimp whiskers that are blown up.

[0009] The suction hood, the suction pipe, and the shrimp whisker collection chamber are connected in sequence; and the shrimp whisker collection chamber has a top side exhaust port.

[0010] The first suction fan is installed inside the suction pipe. By generating negative pressure, it draws the shrimp whiskers inside the suction hood into the suction pipe and then into the shrimp whisker collection chamber. The shrimp whiskers that enter the shrimp whisker collection chamber slowly settle to the bottom of the shrimp whisker collection chamber, while the air is directly discharged from the top side exhaust port.

[0011] Furthermore, the present invention also includes a second conveyor belt and a shrimp head removal device; the shrimp head removal device includes a collection box, a second suction fan array, an exhaust pipe, and a shrimp head collection bin;

[0012] The second conveyor belt is located below the first conveyor belt, the conveying direction of the second conveyor belt is opposite to that of the first conveyor belt, and there is a longitudinal drop between the beginning of the second conveyor belt and the end of the first conveyor belt.

[0013] The collecting box is located in front of the end of the first conveyor belt, and the front of the collecting box is provided with an air intake array and the back is provided with an air outlet. The air intake array is directly opposite the longitudinal drop position. The air outlet is connected to the shrimp head collecting bin through the exhaust pipe.

[0014] The shrimp head collection chamber and the shrimp whisker collection chamber are connected by a connecting port at the top.

[0015] The advantages of this utility model are:

[0016] (1) By setting up a shrimp whisker removal device and a shrimp head removal device, the shrimp whiskers and broken shrimp heads are efficiently removed, thereby improving the quality and appearance of the dried shrimp products.

[0017] (2) Using appropriate wind force as the force on the shrimp head and whiskers, this wind force does not have any impact on the intact shrimp body, and will produce unnecessary movement, which greatly avoids damage to the shrimp body and maintains the integrity of the product.

[0018] (3) The entire process is automated, reducing labor costs and improving production efficiency;

[0019] (4) Shrimp heads and shrimp whiskers are collected by shrimp head collection bin and shrimp whisker collection bin respectively. The shrimp head collection bin and shrimp whisker collection bin are also connected by a connecting port. The floating shrimp whiskers in the shrimp head collection bin are sent to the shrimp whisker collection bin for classification, recycling and reuse, such as for the production of feed, to improve efficiency.

Detailed Implementation Methods

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] Please see Figures 1 to 2 As shown, the dehairing device of this utility model is installed on the shrimp processing boat and connected after the drying process. After a series of processes, the shrimp will produce more shrimp whiskers and some broken shrimp heads. After drying, the shrimp whiskers and shrimp heads lose their adhesion to the whole shrimp body and are in a separated state, which is conducive to removal.

[0026] The dehairing device includes a first conveyor belt 1 and a shrimp whisker removal device 2; the shrimp whisker removal device 2 includes a blower array 21, a suction hood 22, a suction pipe 23, a first suction fan 24, and a shrimp whisker collection chamber 25;

[0027] The blower array 21 is positioned below the first conveyor belt 1, spanning the entire width of the first conveyor belt, and is used to blow the shrimp whiskers on the first conveyor belt 1 so that the shrimp whiskers float above the first conveyor belt.

[0028] The suction hood 22 is positioned above the first conveyor belt 1 and corresponding to the position of the blower array 21, and is used to collect the shrimp whiskers that are blown up and confine the shrimp whiskers within a certain space.

[0029] The suction hood 22, the suction pipe 23 and the shrimp whisker collection chamber 25 are connected in sequence; and the shrimp whisker collection chamber 25 has a top side exhaust port 252.

[0030] The first suction fan 24 is installed inside the suction pipe 23. By generating negative pressure, it draws the shrimp whiskers in the suction hood 22 into the suction pipe 23 and then into the shrimp whisker collection chamber 25. The shrimp whiskers that enter the shrimp whisker collection chamber 25 slowly settle to the bottom of the shrimp whisker collection chamber 25, while the air is directly discharged from the top side exhaust port 252.

[0031] Furthermore, such as Figure 1 and Figure 3 As shown, the present invention also includes a second conveyor belt 3 and a shrimp head removal device 4; the shrimp head removal device 4 includes a collection box 41, a second suction fan array 42, an exhaust pipe 43, and a shrimp head collection bin 44.

[0032] The second conveyor belt 3 is located below the first conveyor belt 1. The conveying direction of the second conveyor belt 3 is opposite to that of the first conveyor belt 1, and there is a longitudinal drop between the first end of the second conveyor belt 3 and the end of the first conveyor belt 1.

[0033] The collection box 41 is located in front of the end of the first conveyor belt 1, and the front of the collection box 41 is provided with an air intake array 411 and the back is provided with an air outlet 412. The air intake array 411 is directly opposite the longitudinal drop position. The air outlet 412 is connected to the shrimp head collection chamber 44 through the exhaust pipe 43. When the shrimp body moves to the end with the first conveyor belt 1, it will fall naturally from the longitudinal drop to the beginning of the second conveyor 3. During the falling process, the remaining shrimp whiskers and broken shrimp heads are in a similar "floating" state. The second suction fan array 42 in front of the longitudinal drop can generate negative pressure to suck away the remaining shrimp whiskers and broken shrimp heads, while the complete shrimp body can be sent to the next process by the second conveyor belt 3.

[0034] The shrimp head collection chamber 44 and the shrimp whisker collection chamber 25 are connected by a connecting port 46 at the top. Since the shrimp head collection chamber 44 also receives some remaining shrimp whiskers when collecting broken shrimp heads, and the shrimp whiskers are still floating under the action of wind when they first enter the shrimp head collection chamber 44, they can enter the shrimp whisker collection chamber 25 through the connecting port 46, thus achieving the classification of shrimp heads and shrimp whiskers.

[0035] The power of the blower array 21, the first suction fan 24, and the second suction fan array 42 are adjusted based on the size of the shrimp. Generally speaking, based on the size of shrimp products currently on the market, the wind speed range of the blower array 21 is 5-10 m / s; the suction range of the first suction fan 24 and the second suction fan array 42 is 1000-2000 Pa.

[0036] The working process of this utility model is as follows:

[0037] S1: Start the production line. During the operation of the first conveyor belt 1, the dried shrimp are transported to the shrimp whisker removal device 2.

[0038] S2: Adjust the wind speed of the blower array 21 and the suction power of the first suction fan 24 to ensure that the shrimp whiskers are effectively blown and sucked in, and sent into the shrimp whisker collection chamber 25 through the suction pipe 23. The shrimp whiskers that enter the shrimp whisker collection chamber 25 slowly settle at the bottom of the shrimp whisker collection chamber 25, while the air is directly discharged from the top side exhaust port 252.

[0039] S3: The shrimp body continues to be conveyed to the end of the first conveyor belt 1 and falls naturally onto the second conveyor belt 3;

[0040] S4: During the falling process, adjust the suction of the second suction fan array 42 in the shrimp head removal device 4 to suck away the remaining shrimp whiskers and broken shrimp heads; and send them into the shrimp head collection chamber 44 through the exhaust pipe 43. Since the shrimp head is heavier than the shrimp whiskers, it can sink in a short time, while the shrimp whiskers enter the shrimp whisker collection chamber 25 through the connecting port 46 under the action of the wind, so as to achieve the classification of shrimp heads and shrimp whiskers.

[0041] S5: Send the dehaired shrimp to the next process, namely the shrimp cooling device.

[0042] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
