[0025] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] like Figure 1 to Figure 2 As shown, 1. Raw material preparation Selection of black beans and red dates Choose high-quality black beans and red dates with full grains, bright color, and no pests and diseases. Black beans should have normal black bean shape and color, and no peculiar smell; red dates should be complete, with smooth skin, and no damage or rot.

[0027] Bean screening equipment to screen black beans The selected black beans are poured into the bean screening equipment. The equipment generates vibration force through a vibration motor, so that the black beans are thrown up on the screen surface and jump forward in a straight line. The aperture of the screen can be set as needed, for example, it can be set to remove impurities, broken and shrunken particles. The qualified black beans after screening are transported to the automatic cleaning equipment through an automatic conveying device.

[0028] Red dates screening machine screening red dates Put the red dates into the red date screening machine, which transports the red dates to the screening area through a conveyor belt. Use mechanical structures or airflow to remove pests, rotten fruits, leaves and impurities. The screened red dates are also transported to the automatic cleaning equipment through an automatic conveying device.

[0029] (II) Raw material cleaning Pre-rinse The automated cleaning equipment first pre-rinses the black beans and red dates. Use low-pressure water flow to preliminarily rinse the black beans and red dates to remove obvious dust and impurities on the surface. The pre-rinsing water flow pressure can be set to 0.2MPa and the rinsing time is 30 seconds.

[0030] soak The next step is soaking. Soak the black beans and red dates in water that meets food hygiene standards. The soaking time is determined by the degree of contamination and quantity of the raw materials, usually 15 minutes. Soaking helps loosen tightly attached impurities and removes any harmful substances such as pesticides that may remain.

[0031] Surf Cleaning Then, surf cleaning is performed. The water flow generated by the equipment simulates the effect of waves. The water flow intensity can be adjusted according to the equipment performance and raw material conditions to further remove impurities. At the same time, the black beans and red dates are rolled in the water to ensure that all parts can be fully cleaned. The surf cleaning time is 5 minutes.

[0032] Spray cleaning The black beans and red dates are rinsed strongly from different angles using a high-pressure spray device. The spray cleaning pressure can be set to 0.5MPa and the spray time is 60 seconds to remove residual tiny impurities and dirt.

[0033] rinsing Finally, rinse the washed black beans and red dates with clean water. Make sure there is no residual detergent and impurities on the surface of the washed materials. The amount of rinsing liquid is determined according to the amount of raw materials, generally twice the weight of the raw materials.

[0034] 3. Steaming Device Setup The washed black beans and red dates are placed in an automated steaming and cooking device, which is equipped with a temperature sensor and a time controller.

[0035] Parameter Adjustment According to the amount of black beans and red dates, the control system automatically adjusts the cooking time and temperature. For example, when the amount of black beans and red dates is 5 kg respectively, the cooking temperature can be set to 100°C and the cooking time is 30 minutes to ensure that they are cooked thoroughly without losing nutrients.

[0036] (IV) Allocation Raw material mixing According to a certain ratio (for example, the mass ratio of black beans to red dates is 3:2), the cooked black beans and red dates are sent to the automated mixing equipment through an automated conveying device for mixing.

[0037] Add seasoning At the same time, add appropriate amount of healthy seasoning, including natural sweeteners (such as sucrose, honey, etc., added in an amount of 10% of the total weight of raw materials), a small amount of edible salt (added in an amount of 1% of the total weight of raw materials), vitamin E (added in an amount of 50 mg / kg of the total weight of raw materials), rosemary extract (added in an amount of 10 mg / kg of the total weight of raw materials), cinnamon powder (added in an amount of 0.5% of the total weight of raw materials) and clove powder (added in an amount of 0.3% of the total weight of raw materials).

[0038] Mix well The automatic mixing equipment is equipped with a mixing speed adjustment device and a uniformity monitoring device. The mixing speed can be adjusted according to the characteristics of the raw materials and seasonings, generally 80 rpm, and the mixing time is 10 minutes to ensure that the seasonings are evenly mixed.

[0039] (V) Forming Equipment Operation The prepared materials are made into flakes through an automated forming device, which has a mold changing device to adjust the shape and size of the flakes as needed.

[0040] Parameter Control The control system automatically controls the material feed speed and pressure to ensure uniform thickness of the chips. For example, the thickness of the chips can be set to 2mm, the feed speed to 3kg / min, and the pressure to 0.8MPa.

[0041] (VI) Drying Device Setup The formed sheets are placed in an automated drying device for drying. The device is equipped with a humidity sensor and a temperature regulating device.

[0042] Parameter Adjustment The control system automatically adjusts the drying temperature and time according to the initial moisture content of the chips and the desired final moisture content (moisture content is controlled below 5%), combined with real-time humidity data. For example, the drying temperature can be set to 80°C and the drying time to 60 minutes to ensure that the chips reach the appropriate moisture content and crispy taste.

[0043] (VII) Packaging Packaging material preparation The dried black bean and red date chips are packaged by automated packaging equipment. The packaging materials are high-barrier multi-layer composite packaging bags that meet food hygiene standards.

[0044] Add desiccant and oxygen absorber The packaging equipment is equipped with devices for adding desiccant and oxygen absorber. The amount of desiccant and oxygen absorber added is determined according to the size of the packaging bag and the number of products. Generally speaking, the amount of desiccant added to each bag of product is 2 grams, and the amount of oxygen absorber added is 1 gram.

[0045] Sterile packaging The packaging process is carried out in a sterile environment to ensure that the product remains healthy and hygienic after packaging. The packaging speed is adjusted according to production efficiency, generally 50 bags / minute.

[0046] 8. Intelligent program control Production demand input Before production begins, the operator inputs production requirements through the human-machine interface, such as the production batch size of 50 kg, product specifications (the thickness of the chips is 2 mm, the shape is round / square, etc.), taste requirements (the type and amount of healthy seasonings, such as 10% sucrose and 0.5% cinnamon powder), and other information.

[0047] Device parameter adjustment The control system calculates the required quantity of black beans and red dates based on the input production batch size, and adjusts the operating parameters of the bean screening equipment and the red date screening machine accordingly. For example, when the production batch size is 50 kg, the screening speed of the bean screening equipment is adjusted to 20 kg / hour, and the screen specifications are selected to be the appropriate aperture to remove impurities, broken and shriveled particles; the conveying speed of the red date screening machine is adjusted to 5 meters / minute.

[0048] In the cleaning process, according to the quantity and degree of contamination of raw materials, the control system automatically adjusts the parameters of the automatic cleaning equipment, such as the pre-rinsing water flow pressure, soaking time, water flow intensity of surfing cleaning, pressure and time of spray cleaning, and water consumption of rinsing. For example, when the quantity of raw materials is large, the pre-rinsing water flow pressure is increased to 0.3MPa, the soaking time is extended to 20 minutes, the surfing cleaning water flow intensity is increased to 10 cubic meters / hour, the spray cleaning pressure is increased to 0.6MPa, and the rinsing water consumption is increased to 3 times the weight of the raw materials.

[0049] For the steaming equipment, the control system automatically adjusts the steaming temperature and time according to the quantity of black beans and red dates and the preset steaming time-temperature curve. For example, when the total amount of black beans and red dates is 50 kg, the steaming temperature is increased to 105°C and the steaming time is extended to 40 minutes.

[0050] During the mixing process, the control system accurately controls the amount of healthy seasoning added and adjusts the stirring speed and time of the automatic stirring equipment according to the input taste requirements. For example, when sweetness needs to be increased, the amount of sucrose added is increased to 12% of the total weight of the raw materials, the stirring speed is increased to 100 rpm, and the stirring time is extended to 15 minutes.

[0051] In terms of molding equipment, the control system automatically adjusts the shape and size of the mold according to product specifications and controls the material feeding speed and pressure. For example, when round crisps need to be produced, the corresponding mold is replaced, the feeding speed is adjusted to 4 kg / min, and the pressure is adjusted to 1 MPa.

[0052] In the drying equipment, the control system automatically adjusts the drying temperature and time according to the initial moisture content of the chips and the desired final moisture content, combined with the real-time humidity data. For example, when the initial moisture content of the chips is high, the drying temperature is increased to 90°C and the drying time is extended to 90 minutes.

[0053] In the packaging process, the control system automatically adjusts the packaging speed of the automated packaging equipment, the amount of desiccant and oxygen absorber added, and the amount of packaging materials used according to the production speed. For example, when the production speed is increased, the packaging speed is increased to 60 bags / minute, and the amount of desiccant and oxygen absorber added is increased accordingly.

[0054] Operation status monitoring and emergency response During the entire production process, the control system monitors the operating status of each device in real time, such as temperature, pressure, speed, humidity and other parameters. Once an abnormal situation is found, an alarm is immediately issued and corresponding emergency measures are taken, such as suspending production, adjusting equipment parameters or performing equipment maintenance. At the same time, the control system will also record various data in the production process for subsequent quality traceability and production optimization.
