Description

Technical Field

[0001] The invention relates to the technical field of dairy product production, in particular to automated production equipment for nutritious and health-care milk. Background Art

[0002] As people's health awareness continues to improve, nutritional health milk, as a food that combines nutrition and health functions, is becoming increasingly popular. In response to the specific nutritional needs of different groups of people, a variety of natural ingredients are often added to cow's milk, such as carrots (juicing), chickpeas (pulping), rye and almonds (grinding), etc., aiming to provide consumers with richer and more balanced nutritional supplements through scientific proportions and processing.

[0003] After the pretreatment of the added ingredients is completed, they are added to the preliminarily treated milk in proportion and mixed. In order to ensure the safety of the product and extend the shelf life, the milk and ingredients must be sterilized by ultra-high temperature (UHT) after mixing. After sterilization, the nutritional health milk needs to be passed into a heat exchanger for rapid cooling. Since a variety of food ingredients are added to the health milk, these ingredients will interact with the protein, fat, etc. in the milk during the cooling process. The sudden drop in temperature makes it easy for certain ingredients in the food ingredients (such as polysaccharides, protein denatured products, and some oils and fats, etc.) to deposit and adhere to the inner wall of the heat exchanger pipe, reducing the heat exchange efficiency of the heat exchanger. This may result in the cooling effect of the nutritional health milk not meeting the standards, thereby affecting its quality.

[0004] Therefore, the present invention proposes an automated production device for nutritious and health-care milk to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0031] The nutritional health milk in this embodiment is composed of milk and food additives, and the food additives include but are not limited to carrots (juicing process), chickpeas (pulping process), rye and almonds (grinding process) and the like.

[0032] Example 1

[0033] See also Figure 1 , an automated production equipment for nutritious and healthy milk, comprising a shell 1 and two heat exchangers 2 arranged in the shell 1 for exchanging heat with the nutritious and healthy milk, the two heat exchangers 2 being arranged opposite to each other, and a gap for the nutritious and healthy milk to flow through in a film-like manner is provided between the two shells 1, a scraper 7 capable of reciprocating along the gap is provided in the gap, and both side edges of the scraper 7 are respectively in contact with opposite sides of the two heat exchangers 2, so as to scrape off the milk and food additives adhered to the opposite sides of the two heat exchangers 2.

[0034] The nutritious and healthy milk after UHT sterilization enters the shell 1 and flows through the gap between the two heat exchange elements 2. The nutritious and healthy milk flows in the gap in a film-like manner to exchange heat with the two heat exchange elements 2, so that the nutritious and healthy milk is quickly cooled to the target temperature range. During the heat exchange process, the scraper 7 moves back and forth along the gap to continuously scrape the opposite sides of the two heat exchange elements 2, thereby avoiding the adhesion of milk and food additives and affecting the heat exchange efficiency, thereby ensuring the heat exchange and cooling effect of the nutritious and healthy milk.

[0035] See also Figure 1 and Figure 2The two heat exchangers 2 are provided with inclined openings on opposite sides of their upper parts to form a drop zone 4. A diverter chamber 5 is provided on the top of the shell 1. A feed pipe 6 is provided on the diverter chamber 5. Drop holes for the nutritional health milk to drop into the drop zone 4 are evenly distributed at the bottom of the diverter chamber 5. The nutritional health milk after UHT sterilization enters the diverter chamber 5 through the feed pipe 6, and then falls into the drop zone 4 through the drop holes, thereby entering the gap between the two heat exchangers 2 for heat exchange.

[0036] See also Figure 1 and Figure 3 In one embodiment of the present invention, a meandering water channel 14 is provided in the heat exchanger 2, a water inlet pipe 8 is provided at the water inlet end of the water channel 14, and a water outlet pipe 9 is provided at the water outlet end thereof. In this embodiment, it should be noted that the heat exchanger 2 is made of a heat-conducting metal material, and cooling water is supplied from the outside, flows in through the water inlet pipe 8, flows through the water channel 14, exchanges heat with the nutritional health milk, and then flows out through the water outlet pipe 9; of course, the heat exchanger 2 can also be a semiconductor temperature control plate or other structure.

[0037] See also Figure 1 , Figure 4 and Figure 5 In one embodiment of the present invention, the width of the gap between the two heat exchange components 2 is adjustable, one of the two heat exchange components 2 is fixed in the shell 1, and a plurality of telescopic components 3 are provided between the other and the shell wall of the shell 1. The telescopic components 3 are telescopic cylinders, electric telescopic rods, etc. in the prior art, which are not limited or elaborated herein.

[0038] In this embodiment, the corresponding heat exchange element 2 is moved closer to / away from another heat exchange element 2 by telescoping a plurality of telescopic elements 3, that is, the amount of nutritious and health milk passing through the gap per unit time is adjusted. The larger the gap width, the greater the amount of passing through, and vice versa. In the actual production of nutritious and health milk, different types of nutritious and health milk will be heated to different temperatures during UHT sterilization. According to the cooling requirements of nutritious and health milk at different temperatures, under the premise of the same cooling conditions (cooling water supply temperature, flow rate, etc.), when the temperature of the nutritious and health milk is relatively low, the gap width can be appropriately increased to increase the flow rate of the nutritious and health milk per unit time (the increase in the gap width increases the "thickness" of the film-like flow of the nutritious and health milk, but because the original temperature of the nutritious and health milk after UHT sterilization is relatively low, it can meet the requirement of cooling the nutritious and health milk to the target temperature range), thereby improving the production efficiency of the nutritious and health milk.

[0039] Furthermore, since the nutritional health milk contains a variety of food additives, when passing through the heat exchanger 2, the film-like state of the nutritional health milk will cause part of the food additives and part of the milk to solidify on the surface of the heat exchanger 2. Therefore, in this embodiment, a scraper 7 is provided to scrape off the food additives on the surface of the heat exchanger 2. The scraper 7 includes a first strip body 701 and a second strip body 702 inserted on the first strip body 701. The first strip body 701 is provided with an insertion groove 704 for inserting the second strip body 702. A plurality of compression springs are provided between the bottom of the insertion groove 704 and the second strip body 702. 705, the scraper strip 7 also includes a sealing member 703 for sealing the gap between the second strip body 702 and the insertion slot 704. The second strip body 702 always has a tendency to move away from the first strip body 701 by compressing the spring 705. The overall width of the scraper strip 7 can be adaptively matched with the movement of the heat exchanger 2 when the gap width is adjusted. The first strip body 701 and the second strip body 702 are respectively in contact and fit with the opposite sides of the two heat exchangers 2. The sealing member 703 is provided to prevent the nutritional health milk from penetrating into the insertion slot 704. Preferably, the sealing member 703 is made of food-grade silicone material.

[0040] Example 2

[0041] Based on Example 1, please refer to Figure 1 , Figure 2 , Figure 6 to Figure 8 The housing 1 is provided with a mounting seat 10, a limiting rod 12 and a screw rod 11 capable of rotating alternately in forward and reverse directions. The mounting seat 10 slides through the mounting seat 10, the screw rod 11 threadably penetrates the mounting seat 10, and the scraper strip 7 is fixedly connected to the mounting seat 10;

[0042] The automated production equipment also includes a driving mechanism 13 for realizing the alternating forward and reverse rotation of the screw rod 11, the driving mechanism 13 includes a collecting bucket 1301 arranged in the shell 1, the collecting bucket 1301 is located below the two heat exchangers 2, a slot 1304 is provided on one side of the shell 1, a sliding iron slide 1307 is provided in the slot 1304, the slot 1304 is located on both sides of the iron slide 1307, and a first electromagnet 1305 and a second electromagnet 1306 for magnetically positioning the iron slide 1307 are provided respectively, the iron slide 1307 is provided with a rotating shaft 1302, a plurality of impact pieces 1303 are evenly arranged on the rotating shaft 1302 in the circumferential direction, and are used to receive the impact of the nutritional health milk falling from the collecting bucket 1301, thereby driving the rotating shaft 1302 to rotate, the rotating shaft 1302 and the screw rod 11 are both provided with a sprocket 1308, and an adaptive telescopic chain 1309 is wound between the two sprockets 1308;

[0043] The shell 1 is provided with a first control button 1310 and a second control button 1311 at both ends of the travel of the scraper strip 7. The first control button 1310 and the second control button 1311 are both triggered by the mounting base 10, wherein the first control button 1310 is used to control the first electromagnet 1305 to be powered on and the second electromagnet 1306 to be powered off, and the second control button 1311 is used to control the first electromagnet 1305 to be powered off and the second electromagnet 1306 to be powered on.

[0044] In this embodiment, initially, the first electromagnet 1305 (or the second electromagnet 1306) is in a powered-on state to magnetically attract the iron slide 1307, and the cooled nutritional health milk flows out from the gap to the collecting bucket 1301 for collection, and then falls through the discharge port of the collecting bucket 1301 to impact the impacted piece 1303 (the impacted piece 1303 on one side of the rotating shaft 1302), thereby driving the rotating shaft 1302 to rotate, and under the transmission action of the telescopic chain 1309, the lead screw 11 is driven to rotate and drive the mounting seat 10 to move toward the second control button 1311 until the second control button 1311 is triggered, the first electromagnet 1305 is controlled to be powered off, and the second electromagnet 1305 is powered on. 306 is energized, and the second electromagnet 1306 after being energized magnetically attracts the iron slide 1307 to move the rotating shaft 1302 to the other side of the discharge port of the collecting bucket 1301, so that the falling nutritional health milk impacts the impacted sheet 1303 on the other side of the rotating shaft 1302 compared with before, thereby driving the screw rod 11 to rotate in the opposite direction compared with before, driving the mounting seat 10 to move toward the first control button 1310 until the first control button 1310 is triggered, and this alternate cycle makes the mounting seat 10 in a reciprocating state, that is, driving the scraper 7 to reciprocate along the gap to continuously scrape the opposite sides of the two heat exchange components 2, thereby preventing food additives from adhering to and affecting the heat exchange efficiency;

[0045] It should be noted that in actual production, the flow rate of nutritious health milk falling from the gap between the two heat exchange components 2 per unit time is relatively large. When falling through the discharge port of the collecting bucket 1301, the impact force is sufficient to drive the rotating shaft 1302 to rotate, thereby driving the screw rod 11 to rotate; in addition, the telescopic chain 1309 contracts / elongates accordingly when the iron slide seat 1307 moves and maintains engagement with the sprocket 1308. It belongs to the prior art and is widely used in agricultural machinery, lifting machinery, conveying machinery and other fields, so it will not be elaborated here.

[0046] Furthermore, in this embodiment, the coagulated milk and food additives scraped off by the scraper 7 fall with the nutritional health milk and hit the impact receiving sheet 1303, so as to disperse the coagulated milk and food additives.

[0047] Furthermore, in the present embodiment, the shell 1 is provided with a soft elastic membrane (made of rubber, silicone or other materials) for closing the card slot 1304, and the soft elastic membrane is provided with a hole adapted to the contour of the iron slide 1307, and the side of the hole is connected to the iron slide 1307. The card slot 1304 is closed by the soft elastic membrane to prevent the nutritional health milk from bursting out and the external bacteria from entering. It should be noted that the soft elastic membrane is relatively loose, so that the resistance is small when the iron slide 1307 slides to adjust its position.

[0048] For further information, see Fig. 9 In this embodiment, the first electromagnet 1305 and the second electromagnet 1306 are both provided with a magnetic member 1312, and the magnetic attraction force of the magnetic member 1312 satisfies the magnetic attraction and positioning function of the iron slide 1307. The first electromagnet 1305 and the second electromagnet 1306 only play the role of increasing the magnetic attraction force to cause the iron slide 1307 to switch positions. For example, the iron slide 1307 is adsorbed and positioned by the magnetic member 1312 provided on the first electromagnet 1305. At this time, the first electromagnet 1305 and the second electromagnet 1306 are both in a power-off state. When the mounting base 10 moves to trigger the second control button 1311, the second electromagnet Iron 1306 is powered on for a certain period of time and then powered off (for example, powered on for 10S and then powered off. The corresponding control technology is existing technology and will not be elaborated here). The magnetic attraction force generated by the second electromagnet 1306 when powered on is much greater than the magnetic attraction force of the magnetic part 1312 on the first electromagnet 1305 on the iron slide 1307, so that the iron slide 1307 slides toward the second electromagnet 1306 and is thus adsorbed and positioned by the magnetic part 1312 on the second electromagnet 1306. In this alternating cycle, the first electromagnet 1305 and the second electromagnet 1306 force the iron slide 1307 to slide and shift, and are not in a continuously powered state, thereby reducing energy loss.

[0049] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
