Description

Technical Field

[0001] The utility model relates to the technical field of food production, and in particular to a PLC intelligent tea beverage precise mixing device. Background Art

[0002] Tea beverages have diverse ingredients, and many factors need to be considered comprehensively. High-quality tea should be selected as the basis, the source of sweetness should be reasonably matched, and acidulants should be appropriately added to balance the taste. At the same time, the nutritional value of the beverage should be enhanced by adding some functional ingredients, and natural pigments should be used to improve the appearance of the product. Sugar, acidulants, edible flavors, vitamin C, pigments, fruit juice and other ingredients will be added to tea beverages as needed.

[0003] When adding ingredients to a tea beverage, the ingredients of the corresponding components are first obtained according to the dosage, and then a mixing device is used to mix the tea beverage and the ingredients to form a finished tea beverage; when mixing the tea beverage and the ingredients, the weighed ingredients are generally put into the tea beverage as a whole for mixing. Some powdered, solid or thick liquid ingredients are difficult to mix and break up, resulting in the tea beverage being easily unevenly mixed with some ingredients, which in turn results in the tea beverage being produced in an unstable manner; at the same time, when mixing some powdered, solid or thick liquid ingredients with the tea beverage, the mixing efficiency is also low. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a PLC intelligent tea beverage precision mixing device to solve the problem that some powdered, solid or thick liquid ingredients are difficult to mix and disperse, resulting in uneven mixing of tea beverages with some ingredients.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model is as follows: a PLC intelligent tea beverage precision mixing device, including a mixing barrel, a stirring rod coaxially installed in the mixing barrel, and a mixing motor driving the stirring rod to rotate, and also includes:

[0006] A premixing cylinder for sequentially placing a plurality of ingredients, wherein a first electronic switch valve is provided on the side wall of the premixing cylinder;

[0007] A stirring blade assembly, the stirring blade assembly is rotatably installed in the bottom of the premixing barrel;

[0008] A stirring motor drives the stirring blade assembly to rotate, and the stirring motor is fixedly installed on the bottom of the premixing barrel;

[0009] A weighing measuring instrument, the upper side of which is fixedly installed with the stirring motor;

[0010] A PLC controller is electrically connected to a first controller for controlling the mixing motor to be turned on or off and a second controller for controlling the stirring motor to be turned on or off. The weighing measuring instrument and the first electronic switch valve are electrically connected to the PLC controller.

[0011] The technical principle of the utility model is as follows: the PLC controller can cooperate with the weighing measuring instrument to record the amount of ingredients in the premixing barrel, thereby controlling the amount of ingredients, and then pre-placing a small portion of tea beverage into the premixing barrel; at the same time, the PLC controller can control the stirring motor to start through the second controller, and the stirring motor drives the stirring blade assembly to perform high-intensity premixing of the ingredients and a small portion of tea beverage, so as to facilitate the rapid breaking up of part of the powdered, solid or thick liquid in the ingredients and mixing them with a small portion of tea beverage, and the PLC controller controls the first electronic switch valve to open, so that the premixed ingredients and a small portion of tea beverage enter the mixing barrel for sufficient mixing, thereby reducing the probability that some of the powdered, solid or thick liquid ingredients are not broken up and mixed, and improving the mixing uniformity between the tea beverage and the ingredients.

[0012] Furthermore, it also includes a batching unit, which includes:

[0017] A third controller controls the sliding block to slide along the supporting slide rail, and the third controller is electrically connected to the PLC controller.

[0018] Through the above arrangement, when adding ingredients, different kinds of ingredients are placed in different conical hoppers in sequence in advance, and the ingredient information in each conical hopper and the amount of different ingredients placed are input into the PLC controller at the same time. At this time, the weighing measuring instrument implements the peeling control of the obtained weighing data to 0, and the PLC controller controls the slider on the conical hopper where the corresponding ingredient is located to move along the supporting slide rail to the side close to the premixing barrel through the third controller, so that the slider drives the corresponding conical hopper to be vertically opposite to the premixing barrel, and the PLC controller controls the second electronic switch valve on the corresponding conical hopper to open, and the ingredients in the conical hopper fall into the premixing barrel. After the weight measured by weighing increases to the weight required by the corresponding ingredient in the PLC controller, the PLC controller controls the second electronic switch valve to close, and the PLC controller controls the slider again through the third controller to drive the corresponding conical hopper away from the premixing barrel; at the same time, the same control steps are adopted to control the next kind of ingredient to be added to the premixing barrel according to the required amount, so as to realize precise and automatic control of the addition of ingredients.

[0019] Furthermore, a first electronic switch valve of the premixing barrel is fixedly connected with a derivation pipe, and one end of the derivation pipe away from the first electronic switch valve can be connected with the upper end of the mixing barrel.

[0026] Through the above arrangement, the rotating shaft can cooperate with a plurality of stirring blades to cut and break up some powdered, solid or thick liquid ingredients, so that the tea beverage and the ingredients can be mixed more evenly.

[0027] Furthermore, an arc-shaped groove is provided at the lower edge of the fixing frame for the top end surface of the mixing barrel to be embedded.

[0028] Through the above arrangement, it is convenient to support and install the fixing frame on the top surface of the mixing barrel, and the arc-shaped groove can fully limit the installation of the fixing frame.

[0029] Furthermore, the mixing motor is fixedly mounted on the fixing frame.
