Description

Technical Field

[0001] The present invention relates to the technical field related to enzyme coix seed, and in particular to a heating device used for enzyme coix seed fermentation. Background Art

[0002] Enzyme coix is the product obtained by allowing coix to interact with a variety of beneficial microorganisms through a specific fermentation process. During the fermentation process, microorganisms will decompose macromolecules such as protein and starch in coix and convert them into small molecule nutrients such as amino acids and oligosaccharides that are more easily absorbed by the human body. At the same time, a variety of enzymes, vitamins, minerals and secondary metabolites with biological activity will be produced. Compared with ordinary coix, enzyme coix may have better nutritional value and physiological activity. For example, it may have more significant effects in promoting digestion, regulating intestinal flora, and enhancing immunity. It has certain applications and market demands in the fields of health food and health preservation. Enzyme coix fermentation has strict temperature requirements. At different fermentation stages, the activity of microorganisms and enzymes in coix is significantly affected by temperature.

The temperature on both sides of the bottom is often low, and the temperature in the middle and upper parts is relatively high. After the circulating pump is started, the low-temperature thermal oil on both sides of the bottom is extracted and sent to the top through the bottom-up pipeline. On the way up, the low-temperature oil and the high-temperature oil exchange heat and continuously absorb the heat of the heating jacket. In this cycle, the thermal oil is continuously mixed and heat-exchanged to avoid local overheating or overcooling, making the temperature in the heating chamber more uniform.

[0016] 2. The heating device for enzyme coix seed fermentation is equipped with a stirring and discharging mechanism. During fermentation, in order to mix the materials evenly, the motor is started to drive the rotating shaft to rotate, so that the stirring shaft and the surface stirring blades rotate synchronously, stirring the coix seed, microorganisms and other raw materials in the fermentation tank, breaking the stratification, promoting full contact of the ingredients, accelerating the fermentation process, and improving efficiency and quality. After the fermentation is completed, the operator operates the discharge valve to drive the ball to rotate so that the discharge port is aligned with the discharge pipe channel.

The base 1401 is connected to the top of the support plate 11, and the fermentation tank 1402 is connected to the top of the base 1401. The feed port 1403 is provided above the fermentation tank 1402, and the sealing cover 1404 is installed on the surface of the feed port 1403. The heating jacket 1405 is connected to the top of the base 1401, and the heating wire 1406 is installed on the outside of the heating jacket 1405. The fermentation tank 1402 and the heating jacket 1405 are connected to each other. A heating chamber 1407 is provided between the fermentation tank 1402, a discharge pipe 1408 is installed on the surface of the fermentation tank 1402, an oil drain pipe 1409 is provided on the surface of the heating jacket 1405, a circulation pump 1410 is installed on the inner side of the base 1401, and a connecting pipe 1411 is connected to the surface of the circulation pump 1410. An oil storage box 1412 is connected above the connecting pipe 1411, and a pipe 1413 runs through the interior of the oil storage box 1412. Through the setting of the heating device 14, the operator opens the sealing cover 1404, and puts the raw materials such as coix seed and microorganisms required for fermentation into the fermentation tank 1402 through the feed port 1403, and then closes the sealing cover 1404 to ensure that a relatively sealed environment is formed inside the fermentation tank 1402. Then, the operator sets the fermentation temperature through the temperature controller 6. The temperature required for fermentation, after the temperature controller 6 receives the set signal, sends a start instruction to the heating wire 1406, and the heating wire 1406 starts to heat up after being energized. Since it is installed on the outside of the heating sleeve 1405, the heat generated will be transferred to the heating sleeve 1405. The heating chamber 1407 is filled with heat-conducting oil. The heat-conducting oil has good thermal conductivity and can quickly absorb the heat transferred from the heating sleeve 1405 and transfer the heat evenly to the entire outer wall of the fermentation tank 1402, so that the raw materials such as coix seed and microorganisms inside the fermentation tank 1402 are in a uniform and suitable temperature environment, which promotes the smooth progress of the fermentation process. At the same time, the thermal insulation layer 7 and the thermal insulation material 8 can reduce heat loss and maintain a stable temperature. In order to make the temperature of the heat-conducting oil more To ensure uniformity and avoid local overheating or overcooling, the circulation pump 1410 on the inside of the base 1401 starts to work. The circulation pump 1410 is connected to the oil storage box 1412 through the connecting pipe 1411. The pipe 1413 passes through the oil storage box 1412 and forms a circulation path from bottom to top through the circulation pump 1410. The circulation pump 1410 extracts the heat transfer oil with a relatively low temperature at the bottom of the heating chamber 1407, and transports it to the oil storage box 1412 through the connecting pipe 1411. Then the heat transfer oil returns to the top of the heating chamber 1407 through the pipe 1413. In this circulation process, the heat transfer oil continues to flow, making the temperature in the entire heating chamber 1407 more uniform, further improving the heating effect of the fermentation tank 1402, and ensuring that the fermentation process is carried out under stable temperature conditions.When fermentation is complete, the fermentation product can be discharged from the discharge pipe 1408 by operating the valve in the stirring and discharging mechanism 15. If the thermal oil in the heating chamber 1407 needs to be replaced or replenished, this can be done through the oil drain pipe 1409. When the thermal oil needs to be replaced, the circulating pump 1410 can also assist in draining the old oil. New thermal oil can be added to the heating chamber 1407 through the oil storage box 1412 or other means to ensure the continuous and stable operation of the heating device 14.

[0021] Furthermore, four identical groups of support legs 3 and shock-absorbing pads 4 are provided at the bottom of the box body 1, and are symmetrically distributed at the four corners of the bottom of the box body 1 with respect to the central axis of the box body 1. Through the arrangement of the support legs 3 and the shock-absorbing pads 4, a stable and balanced support is provided for the box body 1. The symmetrically distributed support legs 3 evenly bear the weight of the box body 1, effectively preventing the box body 1 from tilting or tipping over due to the shift of the center of gravity, and ensuring that the device is placed stably. The shock-absorbing pads 4 can effectively buffer the vibration from the ground, avoid the external vibration from being transmitted to the inside of the box body 1, reduce the interference with the heating device 14 and the internal fermentation process, ensure that the fermentation is carried out in a stable environment, and improve the fermentation success rate and product quality.

[0022] Furthermore, multiple groups of thermal insulation materials 8 are arranged inside the thermal insulation layer 7, and are symmetrically arranged inside the thermal insulation layer 7 on both sides with respect to the central axis of the thermal insulation layer 7. Through the arrangement of the thermal insulation layer 7 and the thermal insulation material 8, the thermal insulation performance of the box 1 is significantly improved. The thermal insulation layer 7 cooperates with the thermal insulation material 8 to effectively prevent the heat inside the box 1 from dissipating outward, reduce heat loss, and maintain a stable temperature inside the box. At the same time, it can also prevent the external ambient temperature from affecting the inside of the box 1, so that the heating device 14 can work under relatively stable temperature conditions, accurately control the fermentation temperature, avoid fermentation abnormalities due to temperature fluctuations, reduce energy consumption, and improve energy utilization efficiency.

[0023] Furthermore, multiple groups of heating rods 9 are arranged on the surface of the insulation layer 7, and are symmetrically arranged on both sides of the interior of the thermostat box 1 with respect to the central axis of the thermostat box 1. Through the arrangement of the heating rods 9, the internal space of the box 1 can be heated evenly and efficiently. Multiple groups of heating rods 9 are symmetrically distributed and can release heat from both sides of the interior of the box 1 at the same time, so that the air in the box is heated more evenly, the temperature gradient is reduced, and local overheating or overcooling is avoided. This helps to ensure that the temperature around the fermentation tank 1402 in the heating device 14 is consistent, providing a stable and suitable temperature environment for enzyme coix seed fermentation, promoting the smooth progress of the fermentation process, and improving the consistency of the fermentation effect.

[0024] Furthermore, the support plate 11 slides in the slide rail 10 through the slider 12 under the action of the force of the handle 13, and the outer wall size of the slider 12 is consistent with the inner wall size of the slide rail 10. Through the arrangement of the slide rail 10, the support plate 11, the slider 12 and the handle 13, the heating device 14 can be easily moved in and out. The operator holds the handle 13 and applies force, and the support plate 11 slides smoothly under the cooperation of the slider 12 and the slide rail 10, and the heating device 14 can be easily pulled out or pushed in from the box body 1. This design facilitates the installation, disassembly, cleaning and maintenance of the heating device 14, improves the ease of use and maintenance efficiency of the device, and reduces the operation difficulty and time cost.

[0025] Furthermore, the two ends of the pipe 1413 are connected to the two sides of the bottom of the heating chamber 1407, and a circulation path from bottom to top is formed by the circulation pump 1410. The arrangement of the circulation pump 1410 and the pipe 1413 greatly optimizes the heat transfer effect of the heat transfer oil in the heating chamber 1407. In the process of the heating wire 1406 heating the heating jacket 1405 and thereby heating the heat transfer oil in the heating chamber 1407, due to the heat transfer characteristics of the liquid and the uneven heating, the temperature of the heat transfer oil at different positions in the heating chamber 1407 will be inconsistent. Usually, the heat transfer oil at the two sides of the bottom is likely to form a lower temperature area, while the temperature of the heat transfer oil in the middle or upper part is relatively high. After the circulation pump 1410 is started, the heat transfer oil at the two sides of the bottom of the heating chamber 1407 with lower temperature is sucked into the pipe 1413. 3. Due to the bottom-up circulation path formed by the pipeline 1413, the low-temperature heat transfer oil is transported to the top of the heating chamber 1407. During the rising process, the low-temperature heat transfer oil exchanges heat with the surrounding high-temperature heat transfer oil, and continuously absorbs the heat transferred by the heating jacket 1405. This circulation allows the heat transfer oil in the heating chamber 1407 to be continuously mixed and heat-exchanged, avoiding the occurrence of local overheating or overcooling, and making the temperature distribution in the entire heating chamber 1407 more uniform, so that heat can be transferred to the fermentation tank 1402 more stably and efficiently, providing a more accurate and uniform temperature environment for enzyme barley fermentation, which helps to improve fermentation efficiency and product quality. At the same time, it can also reduce the impact of thermal stress on the fermentation tank 1402 caused by uneven temperature and extend the service life of the equipment.

[0026] Furthermore, multiple groups of heating wires 1406 are wound around the outer wall surface of the heating sleeve 1405, and the interior of the heating chamber 1407 is filled with heat transfer oil. Through the arrangement of the heating wires 1406 and the heating chamber 1407, efficient and uniform heating of the fermentation tank 1402 is achieved. After the heating wires 1406 are energized and heated, the heat is quickly transferred to the heating sleeve 1405. Since the heating wires 1406 are wound in multiple groups, the heating sleeve 1405 can be heated evenly. The heat transfer oil in the heating chamber 1407 can quickly absorb the heat of the heating sleeve 1405 and evenly transfer the heat to various parts of the fermentation tank 1402. This design enables the fermentation materials such as coix seed in the fermentation tank 1402 to be heated in an all-round and uniform manner, accurately meeting the strict temperature requirements of enzyme coix seed fermentation, promoting the efficient fermentation reaction, and improving the quality and yield of the fermentation products.

[0027] Furthermore, the stirring and discharging mechanism 15 includes a motor 1501, a rotating shaft 1502, a stirring shaft 1503, a stirring blade 1504, a discharge valve 1505, a ball 1506, a discharge port 1507 and an oil drain valve 1508. The motor 1501 is installed inside the base 1401, the output end of the motor 1501 is installed with the rotating shaft 1502, the top of the rotating shaft 1502 is fixedly connected with the stirring shaft 1503, the surface of the stirring shaft 1503 is installed with the stirring blade 1504, the discharge valve 1505 is installed on one side of the discharge pipe 1408, one end of the discharge valve 1505 is connected with the ball 1506, the ball 1506 is arranged inside the discharge pipe 1408, the surface of the ball 1506 is provided with a discharge port 1507, and the oil drain valve 1508 is provided with a discharge port 1507. An oil drain valve 1508 is installed above the tube 1409. Through the setting of the stirring and discharging mechanism 15, when the enzyme barley is fermented in the fermentation tank 1402, in order to make the materials mixed evenly and promote the fermentation reaction to proceed fully, the motor 1501 is started. The motor 1501 serves as a power source, and its output end drives the rotating shaft 1502 to start rotating. Since the upper part of the rotating shaft 1502 is fixedly connected to the stirring shaft 1503, the stirring shaft 1503 will rotate synchronously with the rotating shaft 1502, and the stirring blade 1504 installed on the surface of the stirring shaft 1503 will also rotate accordingly, stirring the barley, microorganisms and other fermentation raw materials in the fermentation tank 1402. This stirring action can break the stratification of the materials and make the various components fully contact. , ensuring the uniformity of the fermentation environment, which is conducive to the better functioning of microorganisms, accelerating the fermentation process, and improving the fermentation efficiency and quality. When the fermentation is completed, the fermented product needs to be discharged from the fermentation tank 1402. At this time, the operator operates the discharge valve 1505 to drive the ball 1506 connected to one end of the discharge valve 1505 to rotate inside the discharge pipe 1408. A discharge port 1507 is provided on the surface of the ball 1506. When the ball 1506 rotates to align the discharge port 1507 with the channel of the discharge pipe 1408, the fermentation tank 1402 is connected to the discharge pipe 1408, and the fermentation product is discharged from the device through the discharge port 1507 and the discharge pipe 1408 under the action of its own gravity or a certain pressure. When discharge is not required, , rotate the discharge valve 1505 in the opposite direction so that the ball 1506 rotates to the discharge port 1507 and is offset from the channel of the discharge pipe 1408. At this time, the discharge pipe 1408 is closed to prevent leakage of fermentation products. During the heating process, the heat transfer oil in the heating chamber 1407 may produce impurities due to long-term use, or need to be replaced or replenished due to other reasons. At this time, the operator can open the oil drain valve 1508 above the oil drain pipe 1409. After the oil drain valve 1508 is opened, the heat transfer oil in the heating chamber 1407 is discharged from the device through the oil drain pipe 1409 under the action of gravity or pressure difference. The operator can control the opening degree and time of the oil drain valve 1508 according to actual conditions to achieve precise control of the discharge of the heat transfer oil.

[0028] Furthermore, the rotating shaft 1502 cooperates with the stirring shaft 1503 through the motor 1501 to form a rotating structure, and the stirring blades 1504 are spirally connected to the surface of the stirring shaft 1503. Through the setting of the stirring blades 1504, the stirring effect of the material in the fermentation tank 1402 is greatly improved. When the spiral stirring blades 1504 rotate under the drive of the stirring shaft 1503, they can generate axial and radial composite stirring forces. In the axial direction, it can make the material flip up and down along the direction of the stirring shaft 1503, avoiding the accumulation of material at the bottom of the fermentation tank 1402, so that the material at the bottom can also fully participate in the fermentation process; in the radial direction, the stirring blades 1504 push the material to do a circular motion, so that the material forms a circulation in the fermentation tank 1402, and promotes the mixing of materials in different areas. This all-round, multi-level stirring method can ensure that the coix seed, microorganisms and nutrients in the fermentation tank 1402 are fully in contact, providing a more uniform growth environment for microorganisms, accelerating the fermentation reaction, and improving the fermentation efficiency and the quality stability of the enzyme product.

[0029] Furthermore, the discharge valve 1505 and the ball 1506 are rotatably connected, and when the discharge valve 1505 rotates, the ball 1506 can be driven to rotate synchronously. By setting the discharge valve 1506 and the ball 1506, precise control of the fermentation product discharge process is achieved. The operator only needs to turn the discharge valve 1505 to easily drive the ball 1506 to rotate in the discharge pipe 1408. When the fermentation product needs to be discharged, the discharge valve 1505 is turned so that the discharge port 1507 on the ball 1506 is aligned with the discharge pipe. When the channels of 1408 are aligned, the fermentation product can flow out smoothly; and when the fermentation process is still in progress or no discharge is needed, the discharge valve 1505 is rotated in the opposite direction to stagger the discharge port 1507 and the channel of the discharge pipe 1408, and the discharge pipe 1408 is closed, effectively preventing the fermentation product from leaking and the outside air and impurities from entering the fermentation tank 1402 and affecting the fermentation quality. This design is simple and flexible to operate, improves the ease of use and reliability of the device, and helps to ensure the smooth progress of the entire enzyme coix seed fermentation production process.

[0030] Working principle: The operator first applies force through the handle 13 to make the support plate 11 smoothly pull out the heating device 14 from the box body 1 under the cooperation of the slider 12 and the slide rail 10, open the sealing cover 1404, and accurately put the coix seed and the microorganisms required for fermentation into the fermentation tank 1402 through the feed port 1403. Then close the sealing cover 1404 and use its precise cooperation with the feed port 1403 to ensure that a relatively sealed environment is formed inside the fermentation tank 1402 to prevent external impurities, microorganisms, etc. from entering and interfering with the fermentation. Then push the heating device 14 back into the box body 1. Then, the operator sets the precise temperature required for fermentation through the temperature controller 6. After receiving the set signal, the temperature controller 6 immediately sends a start instruction to the heating wire 1406 and the heating rod 9. After the heating wire 1406 is energized, multiple groups of heating wires wrapped around the outer wall of the heating jacket 1405 quickly heat up, and the heat is quickly transferred to the heating jacket 1405. The heat-conducting oil in the heating chamber 1407 quickly absorbs and evenly conducts heat to various parts of the fermentation tank 1402 by virtue of its good thermal conductivity, so that the coix seed and microorganisms in the tank are in a uniform and suitable temperature environment. At the same time, the thermal insulation layer 7 and the thermal insulation material 8 work together to effectively prevent the heat loss inside the box 1 and maintain a stable temperature. The multiple groups of heating rods 9 symmetrically distributed on the surface of the thermal insulation layer 7 release heat from both sides of the box 1 at the same time, further making the air in the box heated evenly, reducing the temperature gradient, avoiding local overheating or overcooling, and providing more stable temperature conditions for fermentation. During the fermentation process, the stirring and discharging mechanism 15 inside the base 1401 starts to work, the motor 1501 is started, and its output end drives the rotating shaft 1502 to rotate, thereby causing the stirring shaft 1503 and the stirring blade 1504 with a spiral surface to rotate synchronously. The axial and radial compound stirring force generated by the stirring blade 1504 causes the materials in the fermentation tank 1402 to be mixed in all directions, breaks the stratification, promotes the full contact of various components, creates a more uniform growth environment for microorganisms, accelerates the fermentation process, and improves the fermentation efficiency and quality. At the same time, in order to ensure the uniform temperature of the heat transfer oil in the heating chamber 1407, the circulation pump 1410 works continuously, which extracts the heat transfer oil with lower temperature on both sides of the bottom of the heating chamber 1407, and transports it to the oil storage box 1412 through the connecting pipe 1411, and then passes through the oil storage box 1412. The heat transfer oil passes through the pipe 1413 and returns to the top of the heating chamber 1407. During the circulation process, the heat transfer oil is continuously mixed and heat exchanged to avoid local temperature differences, and the heat is transferred to the fermentation tank 1402 more stably and efficiently. When the fermentation is completed, the operator operates the discharge valve 1505 to drive the ball 1506 to rotate in the discharge pipe 1408 so that the discharge port 1507 is aligned with the discharge pipe 1408 channel. The fermentation product is discharged from the device through the discharge pipe 1408 under its own gravity or a certain pressure. If the heat transfer oil in the heating chamber 1407 produces impurities due to long-term use or needs to be replaced and supplemented, open the drain valve 1508 above the drain pipe 1409. Under the action of gravity or pressure difference, the heat transfer oil is discharged through the drain pipe 1409. The circulation pump 1410 can assist in oil discharge.New thermal oil is added to the heating chamber 1407 via the oil reservoir 1412, ensuring continuous and stable operation of the heating device 14. Throughout the entire operation, the symmetrically distributed support feet 3 and shock-absorbing pads 4 at the bottom of the housing 1 provide stable and balanced support for the device, buffering ground vibrations and reducing interference with the fermentation process. The vents 5 on the side of the housing 1 allow for ventilation when necessary, maintaining a good air condition within the housing 1 and ensuring that the entire device can stably and efficiently complete the enzyme-coix seed fermentation task. The model of the motor 1501 is Y315S-2. This completes the use of the heating device for enzyme-coix seed fermentation.
