Description

Technical Field

[0001] The invention relates to the technical field of feed pellet processing, in particular to a pig feed pellet coating device for inhibiting Maillard reaction. Background Art

[0002] The core goal of inhibiting the Maillard reaction in feed is to maximize the bioavailability of essential amino acids such as lysine, thereby improving the nutritional value of the feed and the production performance of pigs. The Maillard reaction occurs during feed processing (especially high-temperature processing such as puffing, pelleting, and drying), causing amino acids such as lysine to combine with reducing sugars (such as glucose and lactose), forming complexes that are difficult for animals to digest and absorb. For example, a device for reducing amino acid loss during feed mixing disclosed in application number 202110009869.2 includes a body, a speed change space is provided on the left side of the body, a speed change device is provided in the speed change space, a feeding space is provided on the right side, a feeding device is provided in the feeding space, a stirring space is provided below the speed change space, and a lifting device is provided in the stirring space. The present invention can lift the feed in the lower layer of the stirring tank to the upper layer for cooling, promote heat dissipation, and reduce the stirring speed when amino acids are involved in stirring, reduce frictional heat generation, thereby inhibiting the Maillard reaction and reducing the loss of amino acids in the feed; However, in actual application, simply suppressing the Maillard reaction by cooling and dissipating heat is not effective, and some Maillard reactions will still occur. In view of the fact that the coating process will produce an insulating film on the surface of the particles, thereby effectively suppressing the Maillard reaction, the coating film can also reduce the surface oxidation of feed particles, thereby improving the quality and life of the feed. Therefore, a pig feed particle coating device that suppresses the Maillard reaction is designed. Summary of the Invention

[0022] In this application, the pig feed pellet coating process that inhibits the Maillard reaction requires core steps such as material selection, pretreatment, precise coating, and drying and curing to build a coating barrier to block the Maillard reaction; The first design point is that Figure 1 As shown, in the raw material mixing and feeding mechanism, the positive charge inducer can preferably be added to feed grade calcium carbonate, which is purified and non-toxic as food grade or industrial grade and is a commonly used calcium source in pig feed.

[0027] Example 3 As another embodiment of the present invention, the deflection channel includes a first guide plate 5120 and a second guide plate 5130. The first guide plate 5120 and the second guide plate 5130 are arranged relative to each other and staggered by a distance. The opposite surfaces of the first guide plate 5120 and the second guide plate 5130 are continuous convex and concave surfaces. Each vertex of the convex surface is recessed inward to form an airflow transmission groove 5132, which is used to place the first duct nozzle assembly, the second duct nozzle assembly, and the third duct nozzle assembly respectively, and an injection port 5131 is provided at the opening position of the airflow transmission groove 5132.

[0028] Furthermore, the first duct nozzle assembly, the second duct nozzle assembly, and the third duct nozzle assembly have the same structure.

At this time, the two wedge blocks 815 move relative to or apart along the track 818. When the transmission frame 816 drives the top rod 817 to rise, under the transmission connection action of the transmission triangle block 811 and the wedge block 815 on both sides, due to the connection action of the second soft connection channel 513 and the first soft connection channel 512, the third channels 5160 on both sides are expanded outward and lifted up, thereby realizing the change in the angle between the third channel 5160 and the second channel 5150, thereby realizing the deformation and deflection of the flow channel, and then changing the residence time of the particles in the processing channel and the operating state.

[0038] By further setting the raw material mixing feeding mechanism, such as Figure 1 As shown, under the action of the gear power box 314, the stirring blade 313 can be driven to rotate to achieve stirring and mixing of the raw materials. The gear power box 314 can be equipped with a gear drive component, which is an existing mature technology. Under the action of the feed bin 315, it enters the conveying pipe 412. When the second motor 411 is working, it can drive the spiral conveying rod to move spirally, thereby pushing the material into the extrusion part 211. The conveying pipe 412 can act on the middle part of the extrusion part 211, and the material can enter the upper and lower parts of the extrusion part 211.
