Description

Background Technology

[0002] With the continuous improvement of people's living standards, the demand for refrigeration equipment is also increasing. Among refrigeration equipment, quick-freezing machines are widely used in the food processing industry. Quick-freezing machines are mainly divided into tunnel-type quick-freezing machines and spiral quick-freezing machines. In the food quick-freezing process, the food is first placed on a conveyor belt, which carries the food through a low-temperature, sealed cold storage. After a period of time, the food is frozen and then transported outside the storage room to complete the processing.

[0003] In this process, the speed of the conveyor belt determines the freezing time of the food, and thus the freezing effect. If the conveyor belt speed is too fast, the food will not be completely frozen, resulting in substandard products and easy spoilage. If the conveyor belt speed is too slow, it will greatly reduce production efficiency, while increasing energy consumption and production costs. Summary of the Invention

[0046] Figure 5 This is a structural block diagram of an embodiment of a refrigeration control device for a quick-freezing machine according to the present invention. Detailed Implementation

[0047] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] Currently, the freezing control of quick-freezing equipment mainly relies on experience to adjust the conveyor belt speed. An initial time is set during operation, for example, for freezing raw dumplings, each weighing 20g, with a fabric density of 10kg / m³. 2 The feed core temperature is 15℃, and the discharge core temperature is -18℃. The initial freezing time is set to 10 minutes. The freezing quality of the food is observed. If the discharge freezing temperature is higher than -18℃, the freezing time needs to be increased and the conveyor belt speed reduced. If the discharge freezing temperature is lower than -18℃, the freezing time should be appropriately reduced and the conveyor belt speed increased. This method relies on the experience of the personnel, resulting in inaccurate control of the freezing time.

[0049] Reference Figure 1 The diagram illustrates a step flowchart of an embodiment of a freezing control method for a quick-freezing machine according to the present invention. The quick-freezing machine includes: a weighing module 001 disposed at the bottom of a quick-freezing machine conveyor belt 005; the quick-freezing machine conveyor belt 005 passing through a quick-freezing machine chamber 006; and a temperature detection module 002 disposed at the inlet of the quick-freezing machine chamber 006. The weighing module 001 is used to detect the mass information of the item 004 to be frozen, and the temperature detection module 002 is used to detect the temperature information of the item 004 to be frozen.

[0050] In this embodiment of the invention, the quick-freezing equipment may include a quick-freezing chamber 006, a quick-freezing conveyor belt 005, a weighing module 001, and a temperature detection module 002.

[0051] The quick-freezing machine conveyor belt 005 passes through the quick-freezing machine chamber 006, feeding the items to be frozen into the quick-freezing machine chamber 006 in batches. The quick-freezing machine chamber 006 then freezes the items 004. A weighing module 001 is located at the bottom of the quick-freezing machine conveyor belt 005 and can detect the weight of the items 004 before they enter the quick-freezing machine chamber 006, generating mass information for the frozen items. A temperature detection module 002 is located at the inlet of the quick-freezing machine chamber 006 and can detect the inlet temperature of the items 004 before they enter the quick-freezing machine chamber 006, generating temperature information for the items 004.

[0052] The freezing control method for the quick-freezing machine may specifically include the following steps:

[0053] Step 101: Obtain the mass information and the temperature information;

[0054] First, we can obtain the mass information detected by the weighing module 001 and the temperature information detected by the temperature detection module 002.

[0055] Step 102: Determine the target transmission speed based on the quality information and the temperature information;

[0056] Based on the quality and temperature information, calculations are performed to determine the target conveyor speed that the quick-freezing machine conveyor belt 005 needs to achieve when freezing the current item 004 to be frozen.

[0057] Step 103: Obtain the current conveying speed of the quick-freezing machine conveyor belt;

[0058] Then obtain the current conveyor speed of the current quick-freezing machine conveyor belt 005.

[0059] Step 104: In response to the mismatch between the target transmission speed and the current transmission speed, update the current transmission speed according to the target transmission speed;

[0060] Based on the target conveyor speed and the current conveyor speed, it is determined whether the operation of the quick-freezing machine conveyor belt 005 can meet the freezing requirements. When the target conveyor speed and the current conveyor speed do not match, that is, the current freezing time for the item 004 to be frozen is too long or too short, the freezing time needs to be adjusted. In response to the mismatch between the target conveyor speed and the current conveyor speed, the current conveyor speed can be updated according to the target conveyor speed to adjust the conveyor speed of the quick-freezing machine conveyor belt.

[0061] Step 105: Control the freezer conveyor belt based on the updated current conveying speed.

[0062] After updating the current conveying speed, the movement of the quick-freezing machine conveyor belt 005 can be further controlled by the updated current conveying speed. By adjusting the conveying speed of the quick-freezing machine conveyor belt 005, the time that the item to be frozen 004 stays in the quick-freezing machine compartment 006 can be adjusted, thereby adjusting the freezing time of the item to be frozen 004.

[0063] This invention, in its embodiments, acquires mass information detected by a weighing module 001 and temperature information detected by a temperature detection module 002; determines a target conveyor speed based on the mass and temperature information; acquires the current conveyor speed of the quick-freezing machine conveyor belt 005; updates the current conveyor speed based on the target conveyor speed in response to a mismatch between the target and current conveyor speeds; and controls the quick-freezing machine conveyor belt 005 based on the updated current conveyor speed. By detecting the mass and temperature of the feed material, the target conveyor belt speed is determined, thereby controlling the freezing time based on the target conveyor belt speed. This simplifies equipment operation and prevents food spoilage due to substandard freezing or excessively long freezing times that reduce production capacity and cause energy waste.

[0064] Reference Figure 2This document illustrates a flowchart of another embodiment of the freezing control method for a quick-freezing machine according to the present invention. The quick-freezing machine includes: a weighing module 001 disposed at the bottom of a quick-freezing machine conveyor belt 005; the quick-freezing machine conveyor belt 005 passing through a quick-freezing machine chamber 006; a temperature detection module 002 disposed at the inlet of the quick-freezing machine chamber 006; and an image analysis module 003 disposed at the inlet of the quick-freezing machine chamber 006. The weighing module 001 is used to detect the mass information of the item 004 to be frozen; the temperature detection module 002 is used to detect the temperature information of the item 004 to be frozen; and the image analysis module 003 is used to detect the image information of the item 004 to be frozen.

[0065] The structure of quick-freezing equipment can be referenced. Figure 3 The quick-freezing equipment may include a quick-freezing chamber body 006, a quick-freezing conveyor belt 005, a weighing module 001, a temperature detection module 002, and an image analysis module 003.

[0066] The quick-freezing machine conveyor belt 005 passes through the quick-freezing machine chamber 006, feeding the items to be frozen into the quick-freezing machine chamber 006 in batches, where the quick-freezing machine chamber 006 freezes the items 004. A weighing module 001 is located at the bottom of the quick-freezing machine conveyor belt 005. Figure 3 As shown, a module located below the conveyor belt at the left entrance section can detect the weight of the item 004 to be frozen before it enters the quick-freezing chamber 006, generating mass information of the frozen item. An image analysis module 003 is located above the feed inlet of the quick-freezing chamber 006, fixed to the outside of the chamber plate, and can detect the image information of the item 004 to be frozen. A temperature detection module 002 is located at the feed inlet of the quick-freezing chamber 006, as shown... Figure 3 As shown, the temperature detection module 002 can be located below the image analysis module 003. It can detect the feeding temperature of the item to be frozen 004 before it enters the quick-freezing chamber 006 and generate the temperature information of the item to be frozen 004.

[0067] The freezing control method for the quick-freezing machine may specifically include the following steps:

[0068] Step 201: Obtain the mass information and the temperature information;

[0069] During the transfer of the item 004 to be frozen, quality and temperature information can be obtained.

[0070] Specifically, the step of acquiring the quality information and the temperature information includes: periodically acquiring the quality information and the temperature information within a preset detection period.

[0071] Regarding the acquisition of quality and temperature information, quality and temperature information can be acquired periodically within a preset detection period. This allows for the acquisition of quality and temperature information at different points in time during transmission, enabling more accurate control of freezing time.

[0072] The preset detection cycle can be determined according to the type of quick-freezing equipment and the type of the item to be frozen 004. This embodiment of the invention does not make specific limitations on this.

[0073] Step 202: Determine the size of the item based on the item image information;

[0074] In this embodiment of the invention, the size of the item 004 to be frozen can also be determined based on the item image information from the image analysis module.

[0075] In addition, the category of the item to be frozen (004) can be determined based on the item image information, such as different types of food like fish fillets, shrimp, and chicken cutlets.

[0076] Specifically, the step of determining the size of an item based on the item image information includes: extracting features from the item image information to determine material outline data; and determining the size of the item based on the material outline data.

[0077] The item image information includes an image of item 004 to be frozen. This image can be used for identification, feature extraction, and determination of the material outline data. Then, the item size is determined based on the material outline size.

[0078] Methods for feature extraction from object images include, but are not limited to: 1. Edge detection: using edge detection algorithms to identify edges in the image, thereby obtaining the object's contour. 2. Contour discovery: finding the object's contour by searching for connected regions or boundary pixels in the image. This method typically involves binarization and connected region analysis. 3. Morphological contour extraction: using morphological operations (erosion, dilation, opening, closing, etc.) to change the shape of the image, thereby obtaining the object's contour. 4. Model-based methods: using models (such as edge models, visual attention models, etc.) to identify contour features in the image. Those skilled in the art can adopt appropriate methods according to their needs, and the embodiments of this invention do not limit this.

[0079] Step 203: Determine whether the size of the item is greater than a preset size threshold;

[0080] After obtaining the dimensions of the item to be frozen 004, it can be determined whether the item dimensions are greater than a preset size threshold.

[0081] The preset size threshold can be determined based on the inlet size of the quick-freezing machine chamber 006, but this embodiment of the invention does not impose a specific limitation on it.

[0082] Step 204: When the size of the item is greater than the preset size threshold, a warning message is generated;

[0083] When the size of an item exceeds a preset size threshold, it indicates that the item is too large and the item to be frozen 004 cannot enter the quick-freezing chamber 006 for freezing. A warning message can be generated to notify relevant personnel that the item to be frozen cannot be frozen.

[0084] In addition, the operation of the quick-freezing machine's drive belt can be paused to prevent the items to be frozen 004 from getting stuck at the entrance of the quick-freezing machine's storage compartment 006.

[0085] Step 205: When the size of the item is not greater than the preset size threshold, determine the target conveying speed based on the mass information and the temperature information;

[0086] When the item size is not greater than the preset size threshold, it indicates that the size of the item 004 to be frozen is normal, and the item 004 can enter the quick-freezing chamber 006 for freezing. The state of the item 004 to be frozen can be determined based on the quality and temperature information, and the target conveyor speed is determined based on the state of the item 004 to be frozen. The target conveyor speed represents the state of the quick-freezing machine conveyor belt 005 when the item 004 to be frozen is completed.

[0087] In an optional embodiment of the present invention, the step of determining the target conveying speed based on the mass information and the temperature information includes:

[0088] Sub-step S2051: Combine the quality information with a preset quality coefficient, and combine the temperature information with a preset temperature coefficient to determine the target transmission speed.

[0089] In this embodiment of the invention, quality information can be combined with a preset quality coefficient, and temperature information can be combined with a preset temperature coefficient. Then, the two factors of quality and temperature are taken into account to determine the target transmission speed.

[0090] The preset mass coefficient and preset temperature coefficient can be determined according to the actual situation, and the embodiments of the present invention do not limit them.

[0091] Specifically, the step of combining the quality information with a preset quality coefficient and the temperature information with a preset temperature coefficient to determine the target transmission speed includes: calculating the target transmission speed according to a preset speed formula; the preset speed formula is:

[0092] v=(L*k n) / (m*t m )+L*k w / (w-w0)*t w ;

[0093] Where L is the length of the quick-freezing chamber 006, and k n The preset quality coefficient, m is the quality in the quality information, and t is the mass. m t w It is a preset time constant, K w is the preset temperature coefficient, w is the detected temperature in the temperature information, w0 is the standard feed temperature, and v is the target conveying speed.

[0094] In practical applications, the mass of the item to be frozen 004 and its temperature before entering the quick-freezing chamber 006 can be substituted into the preset speed formula to calculate the corresponding conveyor belt speed, which is the target conveyor speed.

[0095] Step 206: Obtain the current conveying speed of the quick-freezing machine conveyor belt;

[0096] The current conveying speed of the quick-freezing machine conveyor belt 005 can be obtained, and the current conveying speed can be used to characterize the current motion state of the quick-freezing machine conveyor belt 005.

[0097] Step 207: In response to the mismatch between the target transmission speed and the current transmission speed, update the current transmission speed according to the target transmission speed;

[0098] Based on the target conveyor speed and the current conveyor speed, it is determined whether the operation of the quick-freezing machine conveyor belt 005 can meet the freezing requirements. When the target conveyor speed and the current conveyor speed do not match, that is, the current freezing time for the item 004 to be frozen is too long or too short, the freezing time needs to be adjusted. In response to the mismatch between the target conveyor speed and the current conveyor speed, the current conveyor speed can be updated according to the target conveyor speed to adjust the conveyor speed of the quick-freezing machine conveyor belt.

[0099] In an optional embodiment of the present invention, the step of updating the current transmission speed according to the target transmission speed in response to a mismatch between the target transmission speed and the current transmission speed includes:

[0100] Sub-step S2071: When the current transmission speed is detected to be greater than the target transmission speed within the preset detection period, in response to the mismatch between the target transmission speed and the current transmission speed, the target transmission speed is used to replace the current transmission speed.

[0101] Within the preset detection period, if the current conveying speed of the current quick-freezing machine conveyor belt 005 is detected to be greater than the target conveying speed, it means that the current speed of the current quick-freezing machine conveyor belt 005 is too fast and the freezing time is insufficient. In order to prevent the subsequent items to be frozen 004 from deteriorating, in response to the mismatch between the target conveying speed and the current conveying speed, the target conveying speed can be used to replace the current conveying speed, that is, the current conveying speed is reduced and the freezing time is extended.

[0102] In an optional embodiment of the present invention, the step of updating the current transmission speed according to the target transmission speed in response to a mismatch between the target transmission speed and the current transmission speed includes:

[0103] Sub-step S2072: After the preset detection period is completed, it is determined that the current transmission speed is less than the target transmission speed. In response to the mismatch between the target transmission speed and the current transmission speed, the minimum speed value among the current transmission speeds is determined.

[0104] Sub-step S2073: Determine the minimum speed value as the current transmission speed.

[0105] After the preset detection cycle is completed, if the current conveying speed of the quick-freezing machine conveyor belt 005 within the preset detection cycle is less than the target conveying speed, it means that the current speed of the quick-freezing machine conveyor belt 005 is too slow, the freezing time is too long, and energy is wasted. In response to the mismatch between the target conveying speed and the current conveying speed, the minimum speed value among the current conveying speeds within the preset detection cycle can be determined as the current conveying speed, that is, the current conveying speed can be appropriately increased to reduce the freezing time.

[0106] Step 208: Control the freezer conveyor belt based on the updated current conveying speed.

[0107] The movement of the quick-freezing machine conveyor belt 005 can be controlled by the updated current conveying speed. By adjusting the conveying speed of the quick-freezing machine conveyor belt 005, the time that the item to be frozen 004 stays in the quick-freezing machine compartment 006 can be adjusted, thereby adjusting the freezing time of the item to be frozen 004.

[0108] After adjusting the current transmission speed, it enters the next cycle and continues to control the freezing time.

[0109] This invention, in its embodiments, acquires mass information detected by weighing module 001 and temperature information detected by temperature detection module 002; determines the size of the item based on the item image information; determines whether the item size is greater than a preset size threshold; generates a warning message when the item size is greater than the preset size threshold; determines a target conveyor speed based on the mass and temperature information when the item size is not greater than the preset size threshold; acquires the current conveyor speed of the quick-freezing machine conveyor belt 005; updates the current conveyor speed based on the target conveyor speed in response to a mismatch between the target conveyor speed and the current conveyor speed; controls the quick-freezing machine conveyor belt 005 based on the updated current conveyor speed; determines the target conveyor belt speed by detecting the mass and temperature of the feed material, thereby controlling the freezing time based on the target conveyor belt speed, simplifying equipment operation, avoiding food spoilage due to substandard freezing, or excessive freezing time leading to reduced production capacity and energy waste; and can automatically issue a warning message when food does not meet specifications, allowing relevant personnel to respond quickly.

[0110] To make the implementation process of the quick-freezing equipment freezing control method described in the embodiments of the present invention clearer to those in the art, an example is given below for illustration:

[0111] The structure of a quick-freezing machine can be as follows: Figure 2 As shown, the weighing module 001 is located below the conveyor belt at the left inlet section, and the image analysis sensor is located above the feed inlet and fixed to the outside of the storage plate. The temperature sensor (i.e., the temperature detection module 002) is located below the image analysis module 003 and measures the feed temperature. By detecting the feed quality, feed temperature, feed type, and analysis specifications, the system calculates the conveyor belt speed, enabling intelligent control.

[0112] Specifically, you can refer to Figure 4 The diagram illustrates a step-by-step flowchart of an example of a freezing control method for a quick-freezing machine according to the present invention.

[0113] When food passes through the weighing section of the conveyor belt, the weighing module 001 detects the weight of this section, i.e., the weight of the item to be frozen 004. Simultaneously, the image analysis module 003 detects the type and specifications of the food. Based on image recognition, foods such as fish fillets, shrimp, and chicken cutlets have specific shapes; for example, fish fillets lack the wooden sticks found on chicken cutlets. By recognizing the outline of the material and comparing it with the system database, the type and specifications of the scanned food can be determined. A temperature sensor detects the feed temperature. Based on the detected temperature and weight information, the conveyor belt speed v (i.e., the target conveyor speed) is calculated. The calculation method is as follows:

[0114] v=(L*k n ) / (m*tm )+L*k w / (w-w0)*t w ,

[0115] Where L is the length of the library, k n It is the quality influence coefficient, m is the quality of the food, and t is the quality influence coefficient. m t w It is the time constant, K w Here, is the temperature influence coefficient, w is the detection temperature, and w0 is the standard feed temperature.
