Description

Technical Field

[0001] This invention relates to the field of heat pump baking technology, and in particular to a control method and related equipment for a heat pump drying device. Background Technology

[0002] Currently, some tobacco growers purchase heat pump drying equipment, and the drying process is carried out by themselves or by hiring curing specialists. The process includes tobacco loading, controlling the drying temperature, and dehumidification. Tobacco loading takes place in the curing barn, and the loading amount cannot be controlled to be exactly the same or nearly the same each time, resulting in significant differences in loading amounts. This leads to variations in curing quality when using the same curing curve to control the heat pump drying equipment, resulting in a decrease in the quality of the finished product. Controlling drying and dehumidification during the drying process requires a high level of technical experience from the operators, demanding subjective judgment from the curing specialists, thus increasing labor costs.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0045] The heat pump drying equipment mentioned in this embodiment of the invention includes a heat pump dryer and a special air conditioner. It can be a single type of heat pump drying equipment deployed alone in the drying room, or it can be a combined deployment of multiple heat pump drying equipment.

[0046] Figure 1 This is a schematic flowchart illustrating the operation of a heat pump drying device according to an embodiment of the present invention, such as... Figure 1 As shown, refer to Figure 2 and Figure 3 This invention provides a control method and related equipment for a heat pump drying device. During heat pump drying, the method first acquires the location information of the heat pump and the material information of the material loaded in the drying chamber, including material weight and type. Based on the location information of the heat pump and the material information, the corresponding baking curve is sequentially searched from at least one server unit 100. According to the baking curve issued by the server unit 100, the heat pump drying device controls the baking process of the material, including operations such as heating, dehumidification, and cooling, precisely controlling the baking process and improving the baking quality of the material.

[0047] In some embodiments of the present invention, a control method for a heat pump drying device is provided, the heat pump drying device comprising at least one heat pump component and at least one server component 100, wherein the at least one heat pump component is remotely communicatively connected to the at least one server component 100; and

[0048] The control method includes:

[0049] S301: Obtain the location information of the at least one heat pump component and the material information of the material being loaded into the drying room;

[0050] S302: Based on the location information and the material information, a baking curve is formed on the at least one server section 100;

[0051] S303: Based on the baking curve, control the at least one heat pump component to adjust the baking parameters in the baking oven.

[0052] According to S301, the acquired information includes the current location, the type of material, and the weight of the material. The weight of the material is detected by several weight detection units 200 built into the heat pump drying equipment, which are evenly distributed. Then, the location information, the type of material, and the weight information are sent to the server unit 100. According to S302, after receiving the current location information and the material information, the server unit 100 filters layer by layer from the baking curve database stored in the server unit 100 until the baking curve that best meets the conditions is selected. According to S303, after obtaining the baking curve locally, the baking parameters of the drying chamber are adjusted according to the baking curve, controlling the heating or cooling of the heat pump and the dehumidification process of the drying chamber, until the material weight is baked to the target weight. The baking process can be precisely controlled according to the baking curve, so that the baking quality of the material in the drying chamber is kept at a constant level.

[0053] The built-in weight detection unit 200 of the heat pump drying equipment can accurately measure the weight of the material during the baking process in real time and display the weight on the display screen of the main unit 300 for local personnel to observe. The main unit 300 is a local master controller that controls the heat pump heating or cooling, dehumidification of the drying room, etc. It is set outside the drying room so that on-site employees can observe the data and monitor the baking situation. The main unit 300 can be a computer or other device that can realize the above control.

[0054] In addition, the server section 100 has multiple servers or occupies a portion of a server to store the baking curve database. Using the baking curves stored in the server section 100 to control the baking state of the baking room instead of the baker's own experience can avoid human judgment errors and ensure that the baking quality of the materials is at the same standard. The main process using the baking curve is as follows: Material is loaded into the material carrier and its weight is displayed in real-time on the host 300, while the weight data is simultaneously transmitted to the server 100. The server 100 displays and stores the material weight information. After the material loading is complete and the on-site personnel confirm on the host 300, the server 100, based on the material type and baking location input on the host 300, queries the baking curve database for the most suitable baking curve according to the material type, weight, and geographical location, and sends the baking curve to the host 300. The host 300 controls the baking process in the baking chamber according to the baking curve via a heat pump and other related equipment. The material carrier is equipped with a weight detection unit 200, which can weigh the material and transmit the weight information to the host 300 and the server 100. The weight detection unit 200 can be a pressure sensor or other instrument capable of measuring, displaying, and transmitting weight data, and can adapt to the highest temperature during baking in the baking chamber.

[0055] In some embodiments of the present invention, the heat pump drying equipment further includes at least one weight detection unit 200, the at least one weight detection unit 200 being communicatively connected to at least one server unit 100; and the acquisition of the material information includes:

[0056] The material weight is measured in real time according to the at least one weight detection unit 200;

[0057] The material information includes the material weight; and the material weight is stored on at least one server section 100.

[0058] The heat pump drying equipment includes multiple weight detection units 200, evenly distributed throughout the drying chamber, to detect the weight of the materials loaded inside. These units 200 display weight information in real time, allowing on-site staff to determine the appropriate loading amount each time. Simultaneously, the loading data is transmitted and stored in real-time on the server unit 100. Currently, growers use paper records to document the final loading weight, which often differs significantly from the weight corresponding to the drying curve, making it difficult to accurately measure. Replacing traditional manual recording with the server unit 100 saves costs. Furthermore, the real-time monitoring of material weight by the weight detection units 200 within the material carrier ensures accuracy.

[0059] In some embodiments of the present invention, the at least one server portion 100 stores at least one baking curve database, the baking curve database storing the mapping relationship between the material information, the location information, and the baking curve; and the control method includes:

[0060] Based on the location information and the material information, the at least one server component 100 is controlled to search for the baking curve from a stored baking curve database.

[0061] Replacing bakers' experience-based judgment with baking curves stored in server section 100 allows for industrial applications. A single baker cannot manage the baking process in multiple ovens, and increasing the number of ovens necessitates a corresponding increase in bakers, thus raising labor costs. Using baking curves stored in server section 100 enables mass production without increasing the number of bakers; only ordinary staff are needed for material loading and baking process supervision. Server section 100 stores a baking curve database, which can be categorized by geographical location, material type, or generation time. This database contains a greater number of baking curves than bakers can memorize, offering more selection. Baking curves can be searched within this database based on material information, location information, and the mapping relationship between the curves. Furthermore, storing baking curves on a server provides stronger security.

[0062] In some embodiments of the present invention, controlling at least one heat pump component according to the baking curve to adjust the baking parameters in the baking oven includes:

[0063] Obtain the weight of the material and the humidity information inside the drying room;

[0064] Based on the baking curve, and using the material weight and humidity information as input values, a preset duration for dehumidifying the baking chamber is obtained to control the at least one heat pump component to dehumidify.

[0065] The dehumidification process, controlled according to the baking curve, replaces the manual dehumidification process performed by the baker. When the baker is not present, the optimal dehumidification time will be missed, reducing the baking quality of the materials. Multiple humidity detection devices are evenly distributed throughout the baking chamber. The heat pump unit includes a dehumidification section, which opens when the humidity or material weight settings are reached to expel moisture from the baking chamber. When the material weight reaches the first set weight value, the main unit controls the dehumidification section to open according to the baking curve, and the dehumidification section closes after running for a first preset time. After dehumidification is complete, the main unit 300 controls the heat pump unit to heat the baking chamber according to the baking curve. When the material... When the material reaches the second preset weight value during baking, the main unit 300 controls the dehumidification section in the baking chamber to open according to the baking curve. The dehumidification section closes after running for the second preset time. Depending on the baking curve, the number of times the material weight reaches the set value for dehumidification varies, not just twice. During the baking process, moisture in the baking chamber is removed in a timely manner according to the weight change of the material to ensure the dryness of the baking chamber and improve the baking effect. Existing dehumidification based on humidity changes cannot guarantee that the material in different locations in the baking chamber is in the same state, resulting in large differences and making it difficult to guarantee the overall quality. However, dehumidification based on weight changes and subsequent heating after dehumidification can ensure the overall average quality of the material.

[0066] When the humidity in the drying room reaches the first set value, the main unit 300 automatically opens the dehumidification section according to the drying curve and keeps it open for a preset time before turning it off. The heat pump drying equipment continues to perform subsequent operations according to the drying curve. While monitoring the changes in material weight in real time, the overall drying process is controlled in conjunction with the humidity monitoring of the drying room, which can significantly improve the drying quality of the material. Depending on the different drying curves, the number of times dehumidification is performed will also vary, and it can be done only once or multiple times.

[0067] In some embodiments of the present invention, after controlling the at least one heat pump component to dehumidify according to the preset duration, the method further includes:

[0068] Based on the baking curve, and with the preset duration as the input value, a preset heat pump temperature is obtained to control the at least one heat pump component to heat the baking chamber.

[0069] The baking oven is equipped with multiple temperature detection units, evenly distributed throughout the oven. After the dehumidification process is completed, the preset heat pump temperature is obtained based on the baking curve and the current material weight. The heat pump unit is then controlled to raise the temperature of the entire baking oven to the preset heat pump temperature to continue the baking process. This heating process is controlled according to the baking curve, and changes at least once depending on the baking curve, until the material weight is baked to the third preset weight. At this point, the cooling operation begins until the material weight reaches the target weight, thus completing the baking process.

[0070] In some embodiments of the present invention, the control method further includes:

[0071] In response to the heat pump being in a standby state, the presence of any living organisms in the drying chamber is detected; if so, the heat pump is prevented from starting and / or an alert signal is issued.

[0072] When preparing for baking, if a human body is detected in the baking room, the heat pump drying equipment will prevent the heat pump from stopping and will also issue a warning signal to allow the person to leave. After the person leaves, the main heat pump drying equipment will start controlling the heat pump to raise the temperature, thus preventing accidents. The manual detection part replaces manual inspection through cameras and other means, which is more convenient and intelligent.

[0073] In some embodiments of the present invention, forming a baking profile on at least one server portion 100 includes:

[0074] S401: Based on the location information and the material information, find the corresponding prior baking curve on the at least one server section 100;

[0075] S402: Obtain the first time information when the prior baking curve was generated, and the prior climate information corresponding to the first time information;

[0076] S403: Based on the difference between the prior climate information and the current climate information, adjust the prior baking curve to obtain the subsequent baking curve, and control the heat pump section with the subsequent baking curve in this and subsequent cycles.

[0077] This embodiment is a technical solution for finding the baking curve corresponding to the weather when the climate changes. According to step S401, the closest prior baking curve is found in the baking curve database on the server part 100 based on the location information and material information. According to step S402, after obtaining the prior baking curve, the first time information when the prior baking curve was generated is found, and then the corresponding prior climate information is found based on the time information. According to step S403, the prior baking curve is adjusted according to the difference between the prior climate information and the current climate information to obtain the subsequent baking curve, so that it corresponds to the current climate information. When the current climate information does not change, the subsequent baking curve will be sent to the host 300 at this time and thereafter. The baking process is controlled according to the subsequent baking curve, avoiding the need to still refer to the prior baking curve to control the baking process, which can improve the baking quality of the material.

[0078] In some embodiments of the present invention, adjusting the prior baking curve includes:

[0079] S501: In response to the fact that the difference between the prior climate information and the current climate information is greater than a first preset condition, search the server part 100 for other climate information whose difference from the current climate information meets a second preset condition.

[0080] S502: Obtain location information on the server section 100 that corresponds to the climate information elsewhere, and second time information generated by the climate information elsewhere;

[0081] S503: Based on the location information and the second time information, obtain the baking curve at another location, and replace the previous baking curve with the baking curve at another location.

[0082] According to step S501, when the difference between the prior climate information and the current climate information is greater than the first preset condition, the server part 100 searches for other climate information whose difference from the current climate information meets the second preset condition, that is, searches for other climate information with a smaller difference from the current climate information; according to step S502, the server part 100 searches for other location information corresponding to other climate information, as well as the second time information generated by other climate information, that is, searches for other location information and the time information generated by other climate information corresponding to the baking curve that meets other climate information; according to step S503, based on other location information and second time information, finds other baking curve that meets the current climate conditions, and sends the other baking curve to the host 300 instead of the prior baking curve, thereby improving the baking quality of the material.

[0083] In some embodiments of the present invention, controlling at least one heat pump component according to the baking curve to adjust the baking parameters in the baking oven includes:

[0084] Based on the baking curve, and using the material weight as the input value, the at least one heat pump component is controlled to cool down the material when the difference between the material weight and the target weight is not greater than a set weight.

[0085] In this embodiment, according to the baking curve, when the difference between the weight of the material and the target weight is no greater than the set weight, the host 300 controls the heat pump section to reduce the temperature of the baking chamber, slowly reduce the moisture in the material, and slowly reduce the weight of the material to the target weight.

[0086] In some embodiments of the present invention, a heat pump drying device includes:

[0087] The system includes at least one heat pump component and at least one server component, the at least one heat pump component being remotely connected to the at least one server component; and a controller 50, the controller including a memory 520 and a processor 510, wherein the memory 520 stores a machine-executable program 41, the machine-executable program 41 being executed by the processor 510 to implement the control method of any of the above.

[0088] A heat pump drying device includes several heat pumps and a server unit 100. The heat pumps are remotely connected to the server unit 100. The heat pump drying device also includes a controller 50, which controls the baking process of the drying chamber according to the baking curve, the weight detection unit 200 in the drying chamber, the humidity detection unit, and the temperature monitoring unit. The temperature of the drying chamber is adjusted by the heat pumps and displayed to on-site and remote personnel by the temperature detection unit. The controller 50 includes a memory 520 and a processor 510. The memory 520 stores a machine-executable program 41 and a baking curve. The machine-executable program 41 includes operations such as heating, cooling, and dehumidification. When the machine-executable program 41 is executed by the processor 510, it implements the control method of any of the above-mentioned functions.

[0089] In some embodiments of this invention, currently, some growers purchase heat pump drying equipment, and the drying process is carried out by the growers themselves or by hiring curing specialists. The process includes tobacco loading, controlling the drying temperature, and dehumidification. Tobacco loading takes place in the curing barn, and the loading amount cannot be controlled consistently each time. Large variations in loading amounts, when using the same curing curve to control curing, can easily lead to differences in curing quality. Furthermore, controlling drying and dehumidification during the curing process requires a high level of technical experience from the operators, demanding subjective judgment from the curing specialists, resulting in high labor costs. This invention solves the problems of large variations in tobacco loading amounts and high labor costs. Secondly, poor quality of dried materials often leads to compensation disputes. The purchaser of the main equipment may claim that the poor drying quality is due to machine problems and seek compensation from the main equipment manufacturer. If the main equipment manufacturer lacks sufficient evidence to prove the reliability of the main equipment, it may suffer serious compensation losses, while also affecting product reputation. This invention controls the drying process by having the curing curve issued by the server, avoiding traceability difficulties caused by human factors and eliminating unnecessary disputes. At the same time, the curing curve is confidential, and advanced drying technology enhances the product's competitiveness in the market.

[0090] In some embodiments of the present invention, a pressure sensor is arranged in the material carrier to measure the weight of the loaded material and display the weight to the operator and the server unit 100. The server unit 100 displays and stores the material weight information. After loading, the operator inputs the material type and baking location (province, city, region) on the host 300. Alternatively, the material type and baking location can be saved in advance to the host 300 or the server unit 100 and changed when changing materials. The server unit 100 stores baking curves, which include baking curves for various materials in different regions. The baking curves for these types of materials vary depending on the region, because the baking curves for the same material in different regions are not necessarily consistent. Moreover, different materials have different characteristics and moisture content, resulting in different baking curves. The same material may have different moisture content due to different growing environments, and the corresponding baking curve will also change with the moisture content. The loading weight of the material is visible and transparent to both the host 300 and the server unit 100. The baking curve is a set of operating parameters used by the main unit to control the baking chamber temperature, dehumidification time points, and dehumidification time based on the weight of the material in the material carrier and the time. The loading personnel can load materials according to standard weights of 100 kg or 200 kg, or any random weight. The operating parameters corresponding to the baking curve can be 100 kg or 200 kg, or any weight. That is, a certain amount of material corresponds to a specific baking curve. The server unit 100 remotely controls and sends the baking curve to the main unit 300 based on the weight of the loaded material. The main unit then runs the baking process according to the baking curve. No manual intervention is required for debugging, saving costs.

[0091] During the drying process, drying time and dehumidification are generally controlled by monitoring temperature and humidity data within the drying chamber. However, temperature and humidity vary in different areas of the drying chamber, making the measured temperature and humidity inaccurate and leading to variations or defects in drying quality. Drying essentially involves removing the moisture contained in the material as quickly as possible through artificial means. Taking roses as an example, their initial moisture content is 75%, and the final moisture content after drying is 14%. Therefore, during the drying process, 61% of the moisture is lost, representing a corresponding weight loss. If 100 kilograms of roses are to be dried, the material should weigh 39 kilograms after the moisture loss. This 39 kilograms is the target parameter for successful and completed drying. During this process, when the material weight decreases from 100 kilograms to 70 kilograms, the drying curve is activated to remove moisture. After a certain period of dehumidification, the temperature is raised again, and when the material weight decreases to 50 kilograms, dehumidification is repeated, and so on, until the target weight is reached, indicating that drying is complete.

[0092] The invention also includes a human body thermal detection unit inside the drying room. When the human body thermal detection unit detects a person inside the drying room, the main unit will not start the heat pump and will issue an alarm to prevent accidents from happening.

[0093] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
