Description

Technical Field

[0001] The invention relates to the technical field of pasteurization machine systems, in particular to a pasteurization machine multi-variety production system and method. Background Art

[0002] When producing ordinary yogurt, the outlet temperature of the first heating is generally controlled at 45-50℃. In this temperature range, common yogurt fermentation bacteria such as Lactobacillus bulgaricus and Streptococcus thermophilus can maintain good activity, ensuring the smooth fermentation process. The outlet temperature required for the first heating in the production of charcoal-roasted yogurt will vary depending on the equipment, process and raw materials. Generally speaking, the common outlet temperature of the first heating is 85-95℃, which can effectively kill bacteria and help the stability of the yogurt product and prevent whey precipitation.

[0003] Sharing one machine to produce ordinary yogurt and charcoal-roasted yogurt eliminates the need to purchase dedicated production equipment for ordinary yogurt and charcoal-roasted yogurt respectively, reducing equipment procurement costs; when the production site is limited, the space in the production workshop can be used more reasonably, making the production layout more compact and efficient; at the same time, it avoids the problem of equipment idleness caused by the separate production of ordinary yogurt and charcoal-roasted yogurt, increases the frequency of equipment use, gives full play to the equipment's production capacity, and reduces the equipment cost per unit product.

[0004] However, there are many limitations to using the same machine to produce ordinary yogurt and charcoal-roasted yogurt. The production processes of ordinary yogurt and charcoal-roasted yogurt are different. Using the same machine may not be able to accurately control parameters such as temperature and time, making it difficult to fully display the unique flavors of the two yogurts. The existing pasteurization equipment can process products at a rate of 5 tons per hour, but because the equipment is only suitable for the production of one product, a series of cleaning and sterilization procedures must be performed in actual operations. Although these procedures ensure the hygiene and safety of the products, they also result in a large consumption of steam, water, electricity, and acid-base chemicals.

[0005] Therefore, it is urgent to propose a pasteurization machine multi-variety production system and method to solve the problems of high energy consumption and low production efficiency in the prior art. Summary of the invention

[0006] In view of the above facts, in order to solve the problems of high energy consumption and low production efficiency in the prior art, the present invention further designs a pasteurization machine multi-variety production system and method.

[0007] To achieve the above object, the present invention adopts the following technical solution:

[0008] Solution 1: Pasteurizer multi-variety production system, including material balance tank, P0 preheating section, P1 preheating section, homogenizer, pasteurization section, insulation section, heat recovery section, ice water cooling section, tower water cooling section, insulation intermediate storage tank, hot water tank;

[0009] The material is connected to the input end of the material balance tank through a pipeline, and the output end of the material balance tank is connected to the P0 preheating section, the P1 preheating section, the homogenizer, the pasteurization section, and the insulation section inlet in sequence. The insulation section outlet is connected to the heat recovery section, the ice water cooling section, the tower water cooling section, and the insulation intermediate storage tank in sequence;

[0010] The process water is connected to the water inlet of the hot water tank through a pipeline, and the hot water tank forms a heat cycle with the P1 preheating section, pasteurization section, insulation section, and heat recovery section;

[0011] The heat recovery section is connected to the inlet of the insulation section through a heat recovery pipeline.

[0012] Furthermore: the material reflux pipeline input end is connected between the material balancing tank and the P0 preheating section, and the material reflux pipeline output end is connected to the material balancing tank input end.

[0013] Further: a first thermometer is installed between the pasteurization section and the heat preservation section;

[0014] A second thermometer is installed between the heat recovery section and the ice water cooling section;

[0015] A third thermometer and an outlet valve are installed between the tower water cooling section and the heat-insulating intermediate storage tank.

[0016] Furthermore: a hot water pump and a proportional valve are installed between the hot water tank and the heat recovery section.

[0017] Further: the heat recovery section is composed of 4 tubes;

[0018] The model of the proportional valve is SAMSON 3372.

[0019] Solution 2: A pasteurization machine multi-variety production method, which is implemented based on the pasteurization machine multi-variety production system described in Solution 1, and the operation process is as follows:

[0020] Step 1: Select the first and second thermometers on the touch screen PID control page, set the set temperature to 98℃ and 96℃, select the 95℃ product button, select "Yes" and turn on the machine;

[0021] Step 2: The machine automatically enters the temperature rising program section and runs the program modification section, closing the ice water valve and tower water valve of the ice water cooling section and tower water cooling section to ensure that the outlet temperature is 95°C;

[0022] Step 3: When the temperature reaches 95°C on the third thermometer at the outlet temperature, the machine starts to enter the sterilization process section. After 3600 seconds, it enters the water circulation section and waits for feeding.

[0023] Step 4: After the pipeline is connected, press the production button on the start screen, the material enters the material balance tank, and then enters the P0 preheating section and the P1 preheating section. After the temperature reaches 75°C, it enters the homogenizer. After the temperature of the pasteurization section reaches 95°C, it enters the insulation section.

[0024] Step 5: The material enters the heat recovery section from the outlet of the insulation section. At this time, the yogurt and hot water are controlled by a proportional valve to ensure that the material temperature at the outlet is 95°C on the third thermometer;

[0025] Step 6: Open the outlet valve and the product will turn brown in the insulated storage tank.

[0026] Further: in the step 2, the program modification section is the program modification section of the proportional valve and the program modification section of the second thermometer.

[0027] Furthermore: the second thermometer is PID-regulated and controlled by the analog input module and the analog output module in the S7300PLC to ensure the opening of the proportional valve, thereby ensuring the stability of the second thermometer.

[0028] Furthermore: the models of the analog input module and the analog output module are 331-7KF02-0AB0 and 332-5HD01-0AB0 respectively.

[0029] Furthermore: the water is controlled by a hot water pump in the hot water tank, circulates between the jacket interlayers of the tubes, exchanges heat with the material, and flows in the opposite direction.

[0030] The beneficial effects of the present invention are:

[0031] 1. The present invention uses a 10T / h pasteurization machine to share a machine with other pasteurized products for production, successfully increasing the production function of the equipment, significantly saving the consumption of energy such as water, electricity, steam, acid, alkali, etc., ensuring the quality of the product and achieving the goal of saving energy.

[0032] 2. The present invention adopts PLC programming technology to perform PID control and adjustment on the heat recovery section and proportional valve added later. Through PID and switch control of the tower water cooling section and ice water cooling section, the pasteurizer can produce three different products with outlet temperatures of 95°C, 43°C and 20°C respectively, achieving the purpose of producing multiple products with one pasteurizer.

[0033] 3. The present invention effectively reduces the workload of employees by improving the use of self-designed new processes and equipment. The workload of employees has been reduced from operating two machines to operating only one machine, and work efficiency has been significantly improved.

[0034] 4. The present invention saves 174,000 yuan a year in terms of energy consumption alone and doubles the production capacity. BRIEF DESCRIPTION OF THE DRAWINGS
