Description

Technical Field

[0001] This invention relates to the field of pig bile powder processing technology, and in particular to a vacuum belt linear temperature-controlled drying equipment and processing technology for pig bile powder. Background Technology

[0002] The dried product of pig bile (from the suidae family) is a yellow or grayish-yellow powder. It has a slightly fishy odor, a bitter taste, and is easily hygroscopic. It clears heat, moistens dryness, detoxifies, and relieves cough and asthma. It is used for feverish thirst, red eyes, sore throat, jaundice, whooping cough, asthma, diarrhea, dysentery, constipation, and carbuncles and boils. Bilirubin is a type of bile pigment and the main pigment in human bile. It is a major metabolite of iron porphyrin compounds in the body, is toxic, and can cause irreversible damage to the brain and nervous system. However, it also has antioxidant functions, inhibiting the oxidation of linoleic acid and phospholipids. Bilirubin is an important clinical basis for diagnosing jaundice and an important indicator of liver function. It also has effects such as promoting digestion, relieving cough and asthma, anti-inflammatory and anti-allergic properties, antimicrobial activity, and antitumor activity. In current technology, pig bile powder is usually obtained by directly drying fresh pig bile after filtration.

[0003] Because pig bile contains bile acids, bile pigments, mucoproteins, and other biological organic matter, these components are generally sensitive to temperature and oxygen. Current traditional pig bile powder processing methods typically employ high temperatures, which easily lead to carbonization and the destruction of effective substances. If temperature control is not properly managed during pig bile powder processing, the effective components in the pig bile can easily deteriorate, reducing the practical value of the pig bile powder. Furthermore, the preparation process requires significant manpower and resources.

[0004] In conclusion, how to make the heat treatment of pig bile powder more efficient and minimize damage to its performance is a problem that needs to be solved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a vacuum belt linear temperature-controlled drying equipment and process for pig bile powder, so as to make the heating treatment of pig bile powder more efficient and energy-saving, and to minimize the damage to the performance of pig bile powder.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention provides a vacuum belt linear temperature-controlled drying device for pig bile powder, including a dryer and a raw material tank for supplying raw materials to the dryer. The raw material tank is connected to a feed pipe, which is equipped with a feed pump. The feed pipe extends into the dryer and has multiple parallel guide pipes. The dryer has multiple parallel drying transmission parts. Each guide pipe independently supplies raw materials to one drying transmission part. The drying transmission part includes a drying belt that is supported and rotated by a drive wheel and a transmission wheel. A heat absorption part is installed through the drying belt. The heat absorption part includes a heat absorption plate located on the lower side of the drying belt and two heat-conducting columns that penetrate the drying belt. The heat-conducting columns are located on the upper side of the heat absorption plate and are integrally formed with the heat absorption plate. The upper end of the heat-conducting column has a circumferential groove. The drive wheel and the transmission wheel have grooves on their circumferential sides that cooperate with the heat absorption plate.

[0008] A heat-conducting strip plate is configured on the upper side of the drying belt to engage with the heat-absorbing part. With the drying belt's transmission direction as the longitudinal direction, the heat-conducting strip plate has a transversely penetrating insertion groove. The vertical side wall of the insertion groove has an engaging protrusion that mates with the circumferential groove. An inner positioning block is also provided on the upper side of the drying belt, engaging between two heat-conducting columns in the same heat-absorbing part. The inner positioning block has an end notch that mates with the circumferential side of the heat-conducting column, and a side groove that mates with the engaging protrusion. The heat-conducting strip plate is transversely inserted into the upper end of the heat-conducting column, at the position of the inner positioning block, through the insertion groove. At least three heating plates are located below the drying zone. Each heating plate has a heat conduction groove on its top side that mates with the heat-absorbing plate of the heat-absorbing section. Inside each heating plate is a heat flow channel, an inlet at one end of the heat flow channel, and an outlet at the other end. The vertical cross-sectional area of ​​the heat flow channel gradually decreases from the inlet to the outlet. The inlet is connected to a heat flow inlet pipe, and the outlet is connected to a return pipe. Each heat flow inlet pipe is equipped with a control valve and a flow meter. A front-position sensing component is located upstream of each heating plate, below the drying zone. This component has a path groove that mates with the heat-absorbing plate. Embedded on the bottom side of the path groove are a photoelectric distance sensing module for vertically upward distance detection and a temperature sensing module for vertically upward temperature detection.

[0009] In the drying equipment of the present invention, the drying belt has a plurality of pairs of mounting through holes, and the heat-conducting column of the heat-absorbing part passes vertically through the mounting through holes.

[0010] In the drying equipment of this invention, the thickness of the heat-absorbing plate is smaller than the depth of the wheel groove.

[0011] In the drying equipment of the present invention, a vertical center through hole is provided in the middle position of the heat-conducting strip plate, and a vertical center screw hole is provided in the middle position of the inner positioning block. Bolts are installed at the positions of the center through hole and the center screw hole.

[0012] In the drying equipment of the present invention, a plugging block is inserted at the side end position of the plugging card slot of the heat-conducting strip board, and the plugging block is provided with a plugging card slot matching the engaging protrusion. Vertical side holes are opened at both side ends of the heat-conducting strip board, a vertical plugging screw hole is opened at the middle position of the plugging block, and bolts are installed at the positions of the side holes and the plugging screw hole.

[0013] In the drying equipment of the present invention, a heat-conducting layer made of copper alloy is embedded on the bottom side surface of the heat-conduction groove of the heating plate, and the lower side of the heat-conducting layer is in contact with the heat flow channel. Multiple continuously distributed roller structures are provided on both vertical side walls of the heat-conduction groove of the heating plate.

[0014] In the drying equipment of the present invention, the top side surface of the inner cavity of the heat flow channel of the heating plate is a horizontal plane structure, the bottom side surface of the inner cavity of the heat flow channel of the heating plate is an inclined slope structure, the injection port is located at the lowest end point position of the inclined slope structure, and the outlet is located at the highest end point position of the inclined slope structure.

[0015] In the drying equipment of the present invention, based on the moving direction of the drying belt: the photoelectric distance sensing module is located upstream of the temperature sensing module.

[0016] The present invention provides a vacuum belt linear temperature control drying treatment process for pig bile powder, which specifically includes the following steps:

[0017] S1. The raw material tank pressurizes and introduces the raw materials into the dryer, and transports them to the upper surface of the drying belt through the material guiding end pipe.

[0018] S2. When the heat absorption plate of the heat absorption part passes through the path groove of the front position sensing component, and the photoelectric distance sensing module detects the distance information conforming to the heat absorption plate, the system obtains the real-time temperature of the heat absorption plate detected by the temperature sensing module, denoted as Tx. In addition, the control system also presets the heating standard reference temperature Tb.

[0019] S3. The heat flow inlet pipe injects heat flow at the standard temperature into the heat flow channel of the heating plate, and the flow meter monitors the fluid flow rate of the heat flow inlet pipe in real time. The control system also presets the fluid reference flow rate Vb of the heat flow inlet pipe.

[0020] S4. When Tx>Tb, the temperature excess amount △Tm = Tx - Tb, F(Vj) ∝ F(△Tm), where Vj is the flow rate reduction amount relative to the fluid reference flow rate Vb. When Tx<Tb, the temperature difference amount △Tn = Tb - Tx, F(Vz) ∝ F(△Tn), where Vz is the flow rate increase amount relative to the fluid reference flow rate Vb.

[0021] Compared with the existing technology, the beneficial effects of the present invention are:

[0022] This invention utilizes multiple independent and concurrent drying belts within a dryer, incorporating a combination of heat-absorbing sections and heat-conducting strips on each belt. Efficient heat transfer is achieved through a grooved path between the heat-absorbing section and the heating plate. Simultaneously, a front-end sensing component is positioned upstream of the heating plate to detect the temperature and heat output of the heat-absorbing section, thereby controlling the heat supply efficiency of the heating plate in a highly efficient and energy-saving manner. This ensures a suitable heating temperature for the pig bile powder raw material, resulting in more efficient and energy-saving heat treatment of the pig bile powder while minimizing damage to its properties.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] Example 1, please refer to Figure 1 The present invention relates to the following structural mating methods:

[0034] The raw materials in raw material tank 2 (such as relatively viscous pig bile slurry after preliminary filtration) are directly fed into the high-vacuum dryer 1 through feed pipe 3 and feed pump 4, spreading onto several drying belts 601 inside the dryer 1 (the sides of the drying belts 601 can be slightly higher than the middle to prevent the pig bile slurry from dripping from the sides). A motor drives a drive wheel 602, which in turn moves the drying belts 601 at a set speed along the direction of the dryer 1 cylinder. Each drying belt 601 has three independent heating plates 7 and one cooling plate 9 underneath. The drying belts 601 are in close contact with the heating plates 7 and cooling plates 9, transferring the energy required for drying to the material through contact heat transfer. The vacuum degree inside the dryer 1 is 1000-5000 Pa, and the raw material temperature is 30-60℃. As the drying belt 601 moves from one end of the cylinder to the other, the raw material is typically dried and cooled within 30-60 minutes. The dried material is then peeled off the drying belt 601 and, through a vertically moving scraper device 14 (with bristles facing the drying belt), is discharged into the crusher 16 via a screw conveyor 15. The crushed material under vacuum is then discharged through the discharge tank 17. Finally, the dry powder is drawn into the dry powder tank 20 through the feeding pipe 18 and the vacuum feeder 19.

[0035] Example 2: The specific structure of the drying equipment of the present invention is as follows:

[0036] Please see Figure 1 The raw material tank 2 is connected to the feed pipe 3, which supplies raw materials to the dryer 1. The feed pipe 3 is equipped with a feed pump 4 and extends into the dryer 1. It is also equipped with multiple parallel guide pipes 5. The dryer 1 is equipped with multiple parallel drying transmission parts 6. A guide pipe 5 is located above the side of each drying transmission part 6. The guide pipe 5 supplies raw materials to the drying transmission part 6. The drying transmission part 6 includes a drying belt 601, which is supported and rotated by a drive wheel 602 and a transmission wheel 603. At least three heating plates 7 are located below the upper drying belt 601.

[0037] Please see Figure 2 , Figure 4 Taking the upper drying belt 601 as an example, the heat absorption part 605 is installed through the drying belt 601 from bottom to top. The heat absorption part 605 includes a heat absorption plate 6051 (e.g., Figure 7 Two heat-conducting pillars 6052 are located on the upper side of the heat-absorbing plate 6051 and are integrally formed with the heat-absorbing plate 6051. The heat-absorbing plate 6051 is located on the lower side of the upper drying zone 601. The heat-conducting pillars 6052 penetrate the drying zone 601. A circumferential groove 60521 is provided at the upper end of the heat-conducting pillar 6052.

[0038] A heat-conducting strip 606 is provided on the upper side of the drying belt 601 in the upper position. The heat-conducting strip 606 is engaged with the heat-absorbing part 605. The heat-conducting strip 606 is pressed and contacted with the drying belt during installation.

[0039] Both the drive wheel 602 and the transmission wheel 603 have grooves 604 on their sides to accommodate the heat-absorbing plate 6051. When the drying belt 601 passes over the drive wheel 602 and the transmission wheel 603, the heat-absorbing plate 6051 passes through the groove area 604, without direct contact with the drive wheel 602 or the transmission wheel 603. The thickness of the heat-absorbing plate 6051 is smaller than the depth of the groove 604; in other words, the dimensions of the heat-absorbing plate 6051 are smaller than the opening width and depth of the groove 604.

[0040] Combination Figure 2 , Figure 3 A heat-conducting layer 706 is embedded on the bottom side of the heat conduction groove 704 of the heating plate 7. The heat-conducting layer 706 is made of copper alloy. The lower side of the heat-conducting layer 706 is in contact with the heat flow channel 701. Other areas of the heating plate 7 can be made of non-metallic materials, so that the heat is absorbed and transferred by the heat-conducting layer 706.

[0041] The heat conduction groove 704 of the heating plate 7 has multiple continuously distributed roller structures 705 on both vertical side walls. After the heat absorption plate 6051 enters the heat conduction groove 704, the roller structures 705 on both sides roll into contact with the side of the heating plate 7, which can reduce resistance and reduce collision wear between the heat absorption plate 6051 and the heating plate 7.

[0042] The top side of the inner cavity of the hot flow channel 701 of the heating plate 7 is a horizontal structure, while the bottom side of the inner cavity of the hot flow channel 701 of the heating plate 7 is an inclined slope structure. The inlet 702 is located at the lowest point of the inclined slope structure, and the outlet 703 is located at the highest point of the inclined slope structure. In essence, the flow cross-section near the inlet 702 is larger and the flow velocity is slower, while the flow cross-section near the outlet 703 is smaller and the flow velocity is faster. This is because the upstream region of the hot flow channel 701 provides more heat to the heat-absorbing part 605, allowing the heat-absorbing part 605 to heat the raw material quickly. However, if the temperature continues to rise rapidly, the heat-absorbing part 605 will continue to absorb more heat, which may damage the properties of the raw material due to excessive temperature. Therefore, the downstream flow velocity of the hot flow channel 701 is accelerated, providing only a "small amount" of heat to the heat-absorbing part 605 to maintain its temperature.

[0043] Please see Figure 2 , Figure 3 , Figure 4The heating plate 7 has a heat conduction groove 704 on its top side that cooperates with the heat absorption plate 6051 of the heat absorption part 605. The heating plate 7 has a heat flow channel 701, an inlet 702 located at one end of the heat flow channel 701, and an outlet 703 located at the other end of the heat flow channel 701.

[0044] Please see Figure 1 , Figure 2 The injection port 702 is connected to a heat flow inlet pipe 10, and the outlet 703 is connected to a return pipe 12. Figure 1 The image only shows the heat inlet pipe 10 and return pipe 12 at both ends of the uppermost heating plate 7. In fact, the heating plates 7 in the two lower layers are also connected to the heat inlet pipe 10 and return pipe 12 in the same way. Each heat inlet pipe 10 is equipped with a control valve 11 and a flow meter 13. The control valve 11 controls the flow rate, and the flow meter 13 monitors the flow rate; the two work together. A front-position sensor assembly 8 is located upstream of each heating plate 7, below the drying zone 601 in the upper layer.

[0045] Please see Figure 4 , Figure 5 The front sensing component 8 is provided with a path groove 801 that cooperates with the heat absorption plate 6051. When the drying belt 601 moves, the heat absorption plate 6051 passes through the area of ​​the path groove 801 of the front sensing component 8. The bottom side of the path groove 801 is embedded with a photoelectric distance sensing module 802 and a temperature sensing module 803. The photoelectric distance sensing module 802 detects the distance vertically upward. When the heat absorption plate 6051 passes by, the detected distance will change. The temperature sensing module 803 detects the temperature of the heat absorption plate 6051 vertically upward.

[0046] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 With the direction of movement of the drying belt 601 as a reference: the photoelectric distance sensing module 802 is located upstream of the temperature sensing module 803, such as... Figure 5 The photoelectric distance sensing module 802 is positioned slightly "forward" of the temperature sensing module 803. This allows the photoelectric distance sensing module 802 to detect the arrival signal of the heat absorber plate 6051 first during sensing. After a very short system delay, the temperature sensing module 803 immediately detects the temperature of the heat absorber plate 6051. This ensures that the temperature sensing module 803 detects the temperature as soon as the middle of the heat absorber plate 6051 reaches above it, guaranteeing the accuracy of the temperature detection of the heat absorber plate 6051.

[0047] Please refer to the following: Figure 6 , Figure 8The drying zone 601 has multiple sets of paired mounting through holes 6011, with two mounting through holes 6011 in each pair. The heat-conducting column 6052 of the heat-absorbing part 605 passes vertically through the mounting through holes 6011.

[0048] The upper drying belt 601 has its transmission direction in the longitudinal direction (combined with...) Figure 1 The heat-conducting strip 606 has a horizontally penetrating insertion slot 6061. The vertical side wall of the insertion slot 6061 has a locking protrusion 6062, which is perfectly matched with the circumferential slot 60521 for horizontal insertion.

[0049] An inner positioning block 607 is placed on the upper side of the drying strip 601. The inner positioning block 607 is engaged between two heat-conducting pillars 6052 of the same heat-absorbing part 605. A vertical center through hole 6063 is opened in the middle of the heat-conducting strip 606, and a vertical center screw hole 6073 is opened in the middle of the inner positioning block 607. Bolts 609 are installed at the positions of the center through hole 6063 and the center screw hole 6073.

[0050] The end notch 6071 is located at the side end of the inner positioning block 607. The inner positioning block 607 is engaged with the heat-conducting column 6052 around the circumference through the end notch 6071. The inner positioning block 607 has a side slot 6072, which cooperates with the engagement protrusion 6062. The heat-conducting strip 606 is inserted laterally into the upper end of the heat-conducting column 6052 and the position of the inner positioning block 607 through the insertion slot 6061. The engagement protrusion 6062 is inserted into the circumferential slot 60521 and the side slot 6072.

[0051] The sealing block 608 is installed on the side of the insertion slot 6061 of the heat conduction strip plate 606. The sealing block 608 has a sealing slot 6081, which is installed in conjunction with the engagement protrusion 6062.

[0052] The heat-conducting strip 606 has vertical edge through holes 6064 on both sides, and the sealing block 608 has a vertical sealing screw hole 6082 in the middle. Bolts 609 are installed at the positions of the edge through holes 6064 and the sealing screw hole 6082.

[0053] Example 3: This invention relates to a vacuum belt linear temperature-controlled drying process for pig bile powder, the details of which are as follows:

[0054] First, the raw material tank 2 pressurizes and introduces the raw materials into the dryer 1, and transports them to the upper surface of the drying belt through the feeding end pipe 5. When the heat absorption plate 6051 of the heat absorption part 605 passes through the path groove 801 of the front position sensing component 8, and the photoelectric distance sensing module 802 detects the distance information conforming to the heat absorption plate 6051, the system obtains the real-time temperature of the heat absorption plate 6051 detected by the temperature sensing module 803, denoted as Tx. In addition, the control system also presets the heating standard reference temperature Tb.

[0055] In addition, the heat flow inlet pipe 10 injects a heat flow at a standard temperature into the heat flow channel 701 of the heating plate 7. It can also be considered that the temperature of the fluid injected into the heat flow channel 701 is fixed. The flow meter 13 monitors the fluid flow rate of the heat flow inlet pipe 10 in real time, and the control system also presets the fluid reference flow rate Vb of the heat flow inlet pipe 10.

[0056] Case 1: When Tx > Tb, the temperature overrun △Tm = Tx - Tb, F(Vj) ∝ F(△Tm), where Vj is the flow rate reduction relative to the fluid reference flow rate Vb, and F(Vj) ∝ F(△Tm) is the function parameter mapping relationship between the flow rate reduction Vj and the temperature overrun △Tm.

[0057] Case 2: When Tx < Tb, the temperature difference △Tn = Tb - Tx, F(Vz) ∝ F(△Tn), where Vz is the flow rate increase relative to the fluid reference flow rate Vb, and F(Vz) ∝ F(△Tn) is the function parameter mapping relationship between the flow rate increase Vz and the temperature difference △Tn.

[0058] Embodiment 4: In the present invention, the raw materials adopt a new method to produce pig bile powder from pig bile and bile after extracting bilirubin. The viscous slurry of pig bile or bile after extracting bilirubin is directly fed into the interior of the dryer 1 under high vacuum through the conveying mechanism, and spread on several drying belts 601 in the dryer 1. The drying belts 601 are driven by a motor to move along the direction of the cylinder of the dryer 1 at a set speed. Three mutually independent heating plates 7 and one cooling plate 9 transfer heat upward, so that the energy required for drying is transferred to the material and the heat is evenly distributed.

[0059] The present invention adopts a constant temperature and vacuum process to prevent the destruction of the effective components of the product and well guarantee the quality of the product. The unique heat absorption and contact heat transfer methods of the present invention greatly improve the heating efficiency and evaporation efficiency, and effectively reduce the production cost.

[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
