Description

Technical Field

[0001] This utility model relates to the field of meat processing technology, specifically to a meat powder drying device. Background Technology

[0002] Meat meal is an animal feed ingredient widely used in animal feed, pet food, and industrial applications. It is mostly processed from various animal by-products. As an animal feed additive, it can provide high-protein nutrition. The crude protein content of meat meal is as high as 50%-80%, which can supplement animals with amino acids (such as lysine and glycine) and promote animal growth.

[0003] Meat meal requires drying during production to remove excess moisture and extend shelf life. Currently, large-scale drying of meat meal involves direct high-temperature hot air baking, which accelerates moisture evaporation to reduce moisture content and achieve dehydration. The applicant has found that meat meal is often directly placed in flat-bottomed trays and put into a dryer. However, current dryers only blow hot air from a single direction, resulting in uneven heating. Meat meal on the surface of the tray is more exposed to the hot air and therefore heats up more easily, resulting in lower moisture content. Meat meal at the bottom of the tray heats up more slowly and has higher moisture content, leading to stratification and uneven moisture content, resulting in poor drying. To ensure the bottom of the tray also meets moisture content standards, the drying time must be extended. Extending the drying time increases production time and reduces efficiency. Furthermore, prolonged high-temperature drying can cause nutrient loss, leading to a decline in meat meal quality. Utility Model Content

[0004] To solve the above problems, this utility model provides a meat powder drying device.

[0005] The technical solution of this utility model is as follows:

[0006] A meat powder drying device includes a housing and a heating module. The housing contains a drying chamber with an opening on one side. A hinged door is located at the edge of the opening. The heating module is disposed within the drying chamber and includes several heating units arranged vertically within the chamber. Each heating unit includes a heating tray and a heating frame. The heating frame includes longitudinal and transverse frames. The longitudinal frames are positioned above corresponding transverse frames, and the transverse frames provide support for the longitudinal frames. Each longitudinal frame includes several parallel longitudinal tubes with several air vents on their surfaces. One end of each longitudinal tube is vertically and fixedly connected to the rear surface of the inner wall of the drying chamber via a conduit. The heating tray is connected to a hot air blower, with one end closed and facing the opening of the chamber. A longitudinal groove is provided on the lower surface of the heating tray at the position where it contacts the corresponding longitudinal pipe. This groove serves two purposes: firstly, it secures the heating tray on the longitudinal frame, preventing it from falling and facilitating the removal or placement of the heating tray by workers; secondly, it increases the contact area of ​​the bottom layer of meat powder in the heating tray, improving its heating rate. The upper longitudinal pipe of the heating tray blows hot air to heat the meat powder on top of the tray, while the lower longitudinal pipe also heats the bottom layer, achieving three-dimensional heating, shortening heating time, improving production efficiency, and ensuring the consistency of the dried meat powder in the heating tray.

[0007] To ensure the stability of the heating tray in the drying chamber and to prevent the longitudinal frame from being deformed by the weight of the heating tray and meat powder, the transverse frame includes several parallel crossbars, the left and right ends of which are respectively fixedly connected to the inner wall surfaces of the left and right sides of the drying chamber.

[0008] To prevent hot air from blowing directly onto the surface of the heating tray from the vents, the vents are located on the left and right sides of the longitudinal tube.

[0009] Furthermore, to prevent the heating tray from blocking the hot air blown out of the vent, a horizontal groove is provided on the bottom of the heating tray at the position opposite to the vent.

[0010] To further prevent hot air from blowing away the meat powder on the surface of the heating tray, a shielding cover connected by a hinge is provided on the upper side of the heating tray. To prevent the shielding cover from affecting the evaporation of moisture in the meat powder, a number of ventilation holes are provided on the shielding cover.

[0011] To prevent the heating tray from sliding out of the drying chamber, a first magnet is provided on the rear surface of the inner wall of the drying chamber facing the heating tray, and a second magnet is provided on the rear surface of the inner wall of the drying chamber at a position opposite to the first magnet. The first magnet and the second magnet have opposite magnetic properties.

[0012] Preferably, the heating tray is provided with a push-pull handle on the side away from the first magnet, which allows the operator to easily push the heating tray into the drying chamber.

[0013] Preferably, in order to allow the upper surface of the uppermost heating tray to also be heated by hot air, a heating rack is also provided above the uppermost heating tray.

[0014] To ensure the heating effect of the hot air blown out of the longitudinal pipe, the distance between two adjacent sets of heating units shall not exceed 5cm.

[0015] Preferably, both the heating tray and the heating rack are made of stainless steel to ensure the structural strength of the heating tray and the heating rack.

[0016] The beneficial effects of this utility model are as follows:

[0017] This utility model discloses a meat powder drying device. The device has vertical pipes above and below the heating tray that can blow hot air, realizing three-dimensional heating of the heating tray. This effectively avoids the stratification of the meat powder in the heating tray during drying. In addition, the bottom surface of the heating tray is provided with crisscrossing vertical and horizontal grooves. These grooves effectively increase the surface area of ​​the bottom surface of the heating tray, making the meat powder at the bottom of the heating tray heat up more quickly and evenly, improving drying efficiency, and avoiding nutrient loss of the meat powder due to excessive heating.

[0025] See Figures 1-4 A meat powder drying device includes a housing 1 and a heating module 2. The housing 1 contains a drying chamber 3, with an opening 4 on one side. The edge of the opening 4 is fitted with a hinged door 5. The heating module 2 is located within the drying chamber 3 and includes several heating units 21 arranged vertically within the drying chamber 3. Each heating unit 21 includes a heating tray 22 and a heating frame 23. The heating frame 23 includes a longitudinal frame 231 and a transverse frame 232. The longitudinal frame 231 is positioned above the corresponding transverse frame 232, and the transverse frame 232 provides support for the longitudinal frame 231. The longitudinal frame 231 includes several parallel longitudinal tubes 233, each with several air vents 234 on its surface. One end of each longitudinal tube 233 is vertically fixed to the rear inner wall of the drying chamber 3 and connected to a hot air blower via a conduit. The other end is closed and faces the opening 4. The hot air blower, once activated, blows hot air... Hot air enters the longitudinal pipe 233 and is then blown out from the air outlet 234 of the longitudinal pipe 233. The lower surface of the heating tray 22 has a longitudinal groove 221 at the position where it contacts the corresponding longitudinal pipe 233. The longitudinal groove 221 can fix the position of the heating tray 22 on the longitudinal frame 231, prevent the heating tray 22 from falling, and facilitate the workers to take out or put in the heating tray 22 from the drying chamber 3. On the other hand, it can increase the contact area of ​​the bottom layer of meat powder in the heating tray 22, improve the heating rate of the bottom layer of meat powder, and thus improve the drying efficiency of the bottom layer of meat powder. The longitudinal pipe 233 on the upper side of the heating tray 22 can blow hot air to heat the meat powder on the upper side of the heating tray 22, while the longitudinal pipe 233 on the lower side of the heating tray 22 can also heat the bottom layer of meat powder, realizing three-dimensional heating, improving heat utilization efficiency, shortening heating time, improving production efficiency, reducing the loss of nutrients in meat powder, improving the quality of meat powder, and ensuring the consistency of drying of meat powder in the heating tray 22.

[0026] To ensure the stability of the heating tray 22 within the drying chamber 3, see [reference needed]. Figure 1 and Figure 3To prevent the longitudinal frame 231 from being deformed by the weight of the heating tray 22 and the meat powder, the transverse frame 232 includes several parallel crossbars 235. The left and right ends of the crossbars 235 are respectively vertically fixed to the inner wall surfaces of the left and right sides of the drying chamber 3. The arrangement of the transverse frame 232 can improve the load-bearing capacity of the heating rack 23 and prevent the longitudinal frame 231 from being crushed by the heating tray 22 and the meat powder.

[0027] To prevent the hot air blown from the vent 234 from directly hitting the surface of the heating tray 22, see [link / reference] Figure 2 and Figure 4 This causes the meat powder on the surface to be blown into the drying chamber 3. The air outlet 234 is set on the left and right sides of the longitudinal pipe 233. The hot air blown out by the air outlet 234 set on the left and right sides of the longitudinal pipe 233 is dispersed to both sides, which prevents the hot air from blowing the meat powder out of the heating tray 22.

[0028] Furthermore, in order to prevent the heating tray 22 from blocking the hot air blown out from the air outlet 234, a horizontal groove 222 is provided on the bottom of the heating tray 22 at the position opposite to the air outlet 234. The horizontal groove 222 can ensure that the hot air blown out from the air outlet 234 passes smoothly through the bottom of the heating tray 22, uniformly heating the bottom of the heating tray 22, and further increasing the surface area of ​​the bottom of the heating tray 22.

[0029] To further prevent the hot air from blowing away the meat powder on the surface of the heating tray 22, see [link / reference needed]. Figure 1 and Figure 2 The upper side of the heating tray 22 is provided with a shielding cover 223 connected by a hinge. In order to prevent the shielding cover 223 from affecting the evaporation of moisture in the meat powder, the shielding cover 223 is provided with a number of ventilation holes 224, thereby ensuring that hot air can enter the heating tray 22 through the ventilation holes 224 and that moisture in the meat powder can be released from the ventilation holes 224.

[0030] To prevent the heating tray 22 from sliding out of the drying chamber 3, see [link / reference] Figure 2 and Figure 3 A first magnet 225 is provided on the rear surface of the inner wall of the heating tray 22 facing the drying chamber 3. A second magnet 6 is provided on the rear surface of the inner wall of the drying chamber 3 at a position opposite to the first magnet 225. The first magnet 225 and the second magnet 6 have opposite magnetic properties. When the operator puts the heating tray 22 into the drying chamber 3, the first magnet 225 and the second magnet 6 can attract each other, thereby adsorbing and fixing the heating tray 22 in the drying chamber 3.

[0031] Preferably, a push-pull handle 226 is provided on the side of the heating tray 22 away from the first magnet 225. The push-pull handle 226 makes it convenient for workers to push the heating tray 22 into the drying chamber 3 or pull the heating tray 22 out of the drying chamber 3.

[0032] Preferably, in order to allow the upper surface of the uppermost heating tray 22 to also be heated by hot air, a heating rack 23 is also provided above the uppermost heating tray 22. The hot air blown out by the longitudinal tube 233 of the heating rack 23 can heat the meat powder in the uppermost heating tray 22, ensuring that the meat powder in the uppermost heating tray 22 is heated evenly.

[0033] To ensure the heating effect of the hot air blown out of the longitudinal pipe 233, the distance between two adjacent sets of heating units 21 is no more than 5cm, so that the hot air blown out of the longitudinal pipe 233 of the two adjacent sets of heating units 21 can influence each other and improve the heat utilization efficiency.

[0034] Preferably, both the heating tray 22 and the heating rack 23 are made of stainless steel, which ensures the structural strength of the heating tray 22 and the heating rack 23, while also preventing the heating tray 22 and the heating rack 23 from rusting and contaminating the meat powder in the heating tray 22.
