Description

Technical Field

[0001] This invention belongs to the field of solid beverage production technology, and specifically relates to a raw material mixing and stirring device for solid beverage processing. Background Technology

[0002] Solid beverages, also known as solid drinks, are solid products that are in powder, granule, or block form. They are made from food raw materials, food additives, etc., and are characterized by being convenient to carry, instant to drink, and having a variety of flavors.

[0003] Effervescent solid beverages are a type of solid beverage. They are liquid beverages that produce bubbles when dissolved by adding effervescent agents (such as citric acid or sodium bicarbonate). During the mixing and stirring of effervescent solid beverage ingredients, it is necessary to strictly adhere to the mixing order of adding the base ingredients (such as maltodextrin or glucose powder) in larger quantities first, followed by adding the effervescent agent.

[0004] In the existing technology, acidic and alkaline substances in the foaming agent are directly mixed during the addition of the foaming agent. Citric acid and sodium bicarbonate are commonly used as acidic and alkaline substances. Citric acid and sodium bicarbonate are prone to reaction, which causes the acidic and alkaline substances to react prematurely, resulting in the failure of the foaming agent or clumping. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art by providing a mixing and blending device for raw materials in solid beverage processing, thereby solving the technical problems in the prior art.

[0006] The objective of this invention can be achieved through the following technical solution: a mixing and blending device for raw materials in solid beverage processing, comprising a mixing tank and two inlets installed on the top of the mixing tank, a discharge port installed at the bottom of the mixing tank, a support mounted on the mixing tank, a transmission assembly mounted on the support, a mixing assembly rotatably mounted inside the mixing tank, the mixing assembly comprising a rotating rod and a rotating sleeve, the rotating sleeve rotatably mounted inside the mixing tank, the output end of the transmission assembly connected to the rotating rod, the rotating rod located inside the rotating sleeve, a stirring rod mounted on the rotating sleeve, a vibration guide baffle mounted on the rotating rod, the vibration guide baffle cooperating with the stirring rod; a sliding groove is formed on the rotating sleeve, the vibration guide baffle sliding within the sliding groove.

[0007] As a further optimization or improvement of this solution, the transmission assembly includes a liftable motor, the output end of which is connected to a transmission head. Transmission bars are installed on both sides of the transmission head. An external gear ring is fixedly installed on the top of the mixing box, and a sun gear is fixedly installed on the rotating rod. Planetary gears are connected between the sun gear and the external gear ring, and a planetary carrier is installed on the top of the planetary gears. A transmission groove is opened at the bottom of the planetary carrier, and a slot is opened at the top of the sun gear. The transmission bars are in transmission engagement with the transmission groove, and the transmission head is in transmission engagement with the slot. When the transmission bars are in transmission engagement with the planetary carrier, the motor drives the rotating rod to decelerate.

[0008] As a further optimization or improvement of this solution, a lifting assembly is installed on the top of the bracket. The lifting assembly includes a housing and a cylinder. The cylinder is installed inside the housing, and the output end of the cylinder is connected to a motor.

[0009] As a further optimization or improvement to this solution, guide bars are installed on both sides of the motor, and the guide bars slide in conjunction with the bracket.

[0010] As a further optimization or improvement of this solution, an inner convex ring is installed on the inner wall of the mixing box, and a striking rod is slidably installed inside the vibration guide baffle. One end of the striking rod contacts the inner convex ring, and the other end is connected to the groove of the vibration guide baffle through a spring.

[0011] As a further optimization or improvement of this solution, a striking head is installed on the striking rod. As the vibration guide baffle rotates, the striking rod reciprocates inside the vibration guide baffle under the action of the inner convex ring, and the striking rod strikes the vibration guide baffle through the striking head.

[0012] The beneficial effects of this invention are: (1) In this invention, the sun gear and the rotating rod are driven to reverse and decelerate in the opposite direction by the reverse rotation of the motor; when the rotating rod reverses, the rotating rod drives the guide baffle to overlap with the stirring rod. At this time, the internal space of the mixing box is divided into two chambers. Then, acidic and alkaline substances are added to the two chambers through the feed inlet one and feed inlet two respectively to avoid direct mixing of acidic and alkaline substances. After the acidic and alkaline substances pass through the two chambers, under the action of the vibration of the guide baffle, the acidic and alkaline substances are mixed with the basic raw materials in the two chambers respectively. After the acid and alkali substances are evenly mixed into the base raw materials, the acidity or alkalinity of the acid-alkali mixture decreases due to the large quantity of the base raw materials. By rotating the motor forward, the vibration guide baffle on the rotating rod is displaced from the stirring rod on the rotating sleeve. As the stirring rod rotates, the two acid-alkali mixtures are combined. Because the acidity or alkalinity of the mixture is reduced, the reaction between the acid and alkali substances can be effectively minimized during the mixing process, reducing the risk of reaction and preventing the gas-generating agent from becoming ineffective.

[0013] (2) At the beginning of mixing, the present invention drives the rotating rod to accelerate by directly driving the sun gear of the motor, and realizes the mixing of the basic raw materials by stirring the stirring rod, thereby improving the mixing efficiency of the basic raw materials. When the acidic and alkaline substances are added to the mixing box through the feed port one and feed port two respectively, the motor drives the planetary gear through the planetary carrier, and drives the rotating rod to decelerate through the transmission shaft system of the planetary gear and the sun gear, thereby reducing the shear force of the stirring rod on the mixing inside the mixing box, avoiding the rupture of the encapsulation layer of acidic and alkaline substances, which would cause the acidic and alkaline substances to react prematurely and cause the gas generator to fail.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] See Figures 1-7A mixing and blending device for raw materials in solid beverage processing includes a mixing tank 1 and two inlets 2 and 3 installed on the top of the mixing tank 1. A discharge port 7 is installed at the bottom of the mixing tank 1. A bracket 4 is installed on the mixing tank 1, and a transmission assembly 6 is installed on the bracket 4. A mixing assembly 8 is rotatably installed inside the mixing tank 1. The mixing assembly 8 includes a rotating rod 801 and a rotating sleeve 802. The rotating sleeve 802 is rotatably installed inside the mixing tank 1. The output end of the transmission assembly 6 is connected to the rotating rod 801. The rotating rod 801 is located inside the rotating sleeve 802. A stirring rod 803 is installed on the rotating sleeve 802. A vibration guide baffle 804 is installed on the rotating rod 801. The vibration guide baffle 804 cooperates with the stirring rod 803. A sliding groove 805 is opened on the rotating sleeve 802, and the vibration guide baffle 804 slides within the sliding groove 805.

[0025] Specifically, the transmission assembly 6 includes a liftable motor 601, the output end of which is connected to a transmission head 603. Transmission bars 604 are installed on both sides of the transmission head 603. An external gear ring 607 is fixedly installed on the top of the mixing box 1. A sun gear 608 is fixedly installed on the rotating rod 801. A planetary gear 610 is connected between the sun gear 608 and the external gear ring 607. A planetary carrier 605 is installed on the top of the planetary gear 610. A transmission groove 606 is opened at the bottom of the planetary carrier 605, and a slot 609 is opened at the top of the sun gear 608. The transmission bars 604 are in transmission engagement with the transmission groove 606, and the transmission head 603 is in transmission engagement with the slot 609. When the transmission bars 604 are in transmission engagement with the planetary carrier 605, the motor 601 drives the rotating rod 801 to decelerate.

[0026] Specifically, a lifting assembly 5 is installed on the top of the bracket 4. The lifting assembly 5 includes a housing 501 and a cylinder 502. The cylinder 502 is installed inside the housing 501, and the output end of the cylinder 502 is connected to a motor 601.

[0027] Specifically, guide bars 602 are installed on both sides of the motor 601, and the guide bars 602 are slidably engaged with the bracket 4.

[0028] It should be noted that foamed solid beverages are mainly composed of a mixture of basic raw materials (such as maltodextrin and glucose powder) and a foaming agent. Common foaming agents are acid-base reactive gas-generating agents, which mainly produce bubbles through the reaction of acidic and alkaline substances. Current mixing methods involve adding the basic raw materials and foaming agent sequentially to a mixing tank. During the addition of the foaming agent, the acidic and alkaline substances in the foaming agent mix directly, triggering a premature reaction that leads to the inactivation or clumping of the gas-generating agent.

[0029] Based on this, in the first step of using this invention, the basic raw materials are first added to the mixing box 1 through feed inlet 2 or feed inlet 3. Simultaneously, motor 601 drives transmission head 603 to rotate forward. Transmission head 603, through transmission cooperation with slot 609, drives rotating rod 801 to rotate synchronously. Rotating rod 801 drives vibration guide baffle 804 to rotate synchronously. (See also...) Figure 6 When the vibration guide baffle 804 and the stirring rod 803 on the rotating sleeve 802 are in a cross shape, the vibration guide baffle 804 drives the rotating sleeve 802 to rotate synchronously through the sliding groove 805. As the rotating sleeve 802 rotates, the rotating sleeve 802 stirs the basic raw materials inside the mixing box 1 through the stirring rod 803. Step 2: The cylinder 502 drives the motor 601 to move upward, causing the transmission head 603 to disengage from the slot 609. The transmission bar 604 engages with the planetary carrier 605 via the transmission groove 606. The motor 601 reverses direction, driving the planetary gears 610 to rotate via the transmission bar 604. The planetary gears 610 then drive the sun gear 608 and the rotating rod 801 in a reverse, decelerating motion. (See also...) Figure 6 When the rotating rod 801 reverses, the rotating rod 801 drives the vibration guide baffle 804 to overlap with the stirring rod 803. After the vibration guide baffle 804 overlaps with the stirring rod 803, the internal space of the mixing box 1 is divided into two chambers. Then, acidic and alkaline substances are added to the two chambers through the feed inlet 2 and feed inlet 3 respectively, so as to avoid direct mixing of acid and alkaline substances. After the acid and alkaline substances pass through the two chambers, under the vibration of the vibration guide baffle 804, the acid and alkaline substances are mixed with the basic raw materials in the two chambers respectively. After the acid and alkali substances are evenly mixed into the base raw materials, the acidity or alkalinity of the acid-alkali mixture decreases due to the large quantity of the base raw materials. The forward rotation of motor 601 causes the vibration guide baffle 804 on the rotating rod 801 to be offset from the stirring rod 803 on the rotating sleeve 802. As the stirring rod 803 rotates, the two acid-alkali mixtures are combined. Because the acidity or alkalinity of the mixture is reduced, the reaction between acid and alkali substances can be effectively reduced during the mixing process, lowering the reaction risk and preventing the gas-generating agent from becoming ineffective.

[0030] It should be noted that the acidic and alkaline substances in the foaming agent generally need to be encapsulated before being added to mixing tank 1. The encapsulation process is existing technology and will not be elaborated upon in this application. The encapsulation process mainly involves protecting the acidic and alkaline substances with encapsulating materials to reduce acid-base reactions during mixing. At the beginning of mixing, i.e., during the addition of the basic raw materials, a high stirring speed is required due to the large quantity of the basic raw materials. When the foaming agent is added to mixing tank 1, the high stirring speed acting on the foaming agent can easily cause the encapsulation layer of the acidic and alkaline substances to rupture, leading to premature reaction of the acidic and alkaline substances.

[0031] Based on this, at the beginning of mixing, the present invention drives the rotating rod 801 to accelerate by directly driving the sun gear 608 through the motor 601, and the stirring rod 803 is used to stir the basic raw materials, thereby improving the mixing efficiency of the basic raw materials. When acidic and alkaline substances are added to the mixing box 1 through the feed inlet 2 and feed inlet 3 respectively, the motor 601 drives the planetary gear 610 through the planetary carrier 605. Through the transmission relationship between the planetary gear 610 and the sun gear 608, the rotating rod 801 is driven to decelerate, thereby reducing the shear force of the stirring rod 803 on the mixture inside the mixing box 1, avoiding the rupture of the encapsulation layer of acidic and alkaline substances, which would cause the acidic and alkaline substances to react prematurely and cause the gas generating agent to fail.

[0032] It should be noted that other raw materials, such as flavorings and colorings, need to be added to mixing tank 1 at the end.

[0033] See Figures 5-7 The inner wall of the mixing box 1 is equipped with an inner convex ring 9, and the vibration guide baffle 804 is slidably installed with a striking rod 806 inside. One end of the striking rod 806 contacts the inner convex ring 9, and the other end is connected to the groove of the vibration guide baffle 804 through a spring 807.

[0034] Specifically, a striking head 808 is installed on the striking rod 806. As the vibration guide baffle 804 rotates, the striking rod 806 reciprocates inside the vibration guide baffle 804 under the action of the inner convex ring 9. The striking rod 806 strikes the vibration guide baffle 804 through the striking head 808.

[0035] It should be noted that when the rotating rod 801 drives the vibration guide baffle 804 to rotate, the striking rod 806 reciprocates inside the vibration guide baffle 804 under the action of the inner convex ring 9. The striking rod 806 strikes the vibration guide baffle 804 through the striking head 808, causing the vibration guide baffle 804 to vibrate. The vibration of the vibration guide baffle 804 prevents acid and alkali substances from absorbing moisture and clumping.

[0036] The implementation principle of this invention is as follows: The usage steps of this invention are as follows; The first step involves adding the basic raw materials into the mixing box 1 through inlet 2 or inlet 3. Simultaneously, motor 601 drives transmission head 603 to rotate forward. Transmission head 603, through its transmission cooperation with slot 609, drives rotating rod 801 to rotate synchronously. Rotating rod 801 then drives vibration guide baffle 804 to rotate synchronously. (See [link to relevant documentation]). Figure 6 When the vibration guide baffle 804 and the stirring rod 803 on the rotating sleeve 802 are in a cross shape, the vibration guide baffle 804 drives the rotating sleeve 802 to rotate synchronously through the sliding groove 805. As the rotating sleeve 802 rotates, the rotating sleeve 802 stirs the basic raw materials inside the mixing box 1 through the stirring rod 803. Step 2: The cylinder 502 drives the motor 601 to move upward, causing the transmission head 603 to disengage from the slot 609. The transmission bar 604 engages with the planetary carrier 605 via the transmission groove 606. The motor 601 reverses direction, driving the planetary gears 610 to rotate via the transmission bar 604. The planetary gears 610 then drive the sun gear 608 and the rotating rod 801 in a reverse, decelerating motion. (See also...) Figure 6 When the rotating rod 801 reverses, the rotating rod 801 drives the vibration guide baffle 804 to overlap with the stirring rod 803. After the vibration guide baffle 804 overlaps with the stirring rod 803, the internal space of the mixing box 1 is divided into two chambers. Then, acidic and alkaline substances are added to the two chambers through the feed inlet 2 and feed inlet 3 respectively, so as to avoid direct mixing of acid and alkaline substances. After the acid and alkaline substances pass through the two chambers, under the vibration of the vibration guide baffle 804, the acid and alkaline substances are mixed with the basic raw materials in the two chambers respectively. After the acid and alkali substances are evenly mixed into the base raw materials, the acidity or alkalinity of the acid-alkali mixture decreases due to the large quantity of the base raw materials. The forward rotation of motor 601 causes the vibration guide baffle 804 on the rotating rod 801 to be offset from the stirring rod 803 on the rotating sleeve 802. As the stirring rod 803 rotates, the two acid-alkali mixtures are combined. Because the acidity or alkalinity of the mixture is reduced, the reaction between acid and alkali substances can be effectively reduced during the mixing process, lowering the reaction risk and preventing the gas-generating agent from becoming ineffective.

[0037] Specifically, the acidic and alkaline substances in the foaming agent generally need to be encapsulated before being added to mixing tank 1. The encapsulation process mainly involves using encapsulation materials to protect the acidic and alkaline substances, thereby reducing acid-base reactions during mixing. At the beginning of mixing, i.e., during the addition of the base raw materials, a high stirring speed is required due to the large quantity of the base raw materials. When the foaming agent is added to mixing tank 1, the high stirring speed acting on the foaming agent can easily cause the encapsulation layer of the acidic and alkaline substances to rupture, leading to premature reaction of the acidic and alkaline substances.

[0038] Based on this, at the beginning of mixing, the present invention drives the rotating rod 801 to accelerate by directly driving the sun gear 608 through the motor 601, and the stirring rod 803 is used to stir the basic raw materials, thereby improving the mixing efficiency of the basic raw materials. When acidic and alkaline substances are added to the mixing box 1 through the feed inlet 2 and feed inlet 3 respectively, the motor 601 drives the planetary gear 610 through the planetary carrier 605. Through the transmission relationship between the planetary gear 610 and the sun gear 608, the rotating rod 801 is driven to decelerate, thereby reducing the shear force of the stirring rod 803 on the mixture inside the mixing box 1, avoiding the rupture of the encapsulation layer of acidic and alkaline substances, which would cause the acidic and alkaline substances to react prematurely and cause the gas generating agent to fail.
