Description

Technical Field

[0001] The present invention relates to the technical field of automatic food preparation equipment, and in particular to a cleaning-free fully automatic food preparation equipment and a use method thereof. Background Art

[0002] For example, desserts such as yogurt and ice cream are popular snack foods among modern people. Adding oatmeal, fruit, jam and various toppings to yogurt or ice cream is becoming more and more popular among young people and children. This kind of snack food is not only nutritious but also has rich taste and has a very good market prospect.

[0003] Modern factories can provide yogurt or ice cream with large-scale production, but the products are often inactivated and the nutrition is greatly reduced; and the videos that are refrigerated and fresh can only be bought in specific retail places; in addition, large-scale production inevitably involves the problems of preservation and food additives, especially the inability to add fresh ingredients such as fresh fruits; and the variety is limited, and it cannot be customized according to personal taste;

[0004] Homemade snacks are one of the options, but it is time-consuming and labor-intensive. Many families cannot prepare all the ingredients. Only a few families can often make this snack by themselves.

[0005] Due to the above reasons, some specialized yogurt shops or fruit salad shops have emerged in cities; however, these shops still rely on simple tools to make food by hand, which requires a lot of manpower, the quality is not stable enough, the preservation of ingredients is not in a closed and clean environment, and the cleaning process is cumbersome. The sanitary conditions are poor, coupled with high rents and labor costs, often lead to the store closing down quickly; the unmanned ice cream machines that appear on the market today are simply transplanted from the food factory assembly line technology. In actual use, they have the following many defects: (1) The solid ingredients use a screw feeding mechanism. The screw feeding mechanism is suitable for factory assembly line production, but it will bring a series of defects and even food safety risks when used in unmanned vending equipment. Specifically, they include: a. It cannot be dismantled for cleaning; on-site cleaning is not only cumbersome, but also extremely difficult to effectively clean the dead corners in the mechanism; b. The screw mechanism is large in size, and multiple ingredients can only share one, which cannot avoid the problem of odor contamination; c. The characteristics of the screw mechanism will squeeze and crush the ingredients, and it is only suitable for powder or finely divided granular ingredients; (2) Other liquid ingredients use fixed cavity containers and pump-type feeding solutions, which still bring cleaning difficulties and potential food safety risks. (3) Other forms of ingredients such as thick slurry particles, pastes, freshly cut fruits and other large particles are not suitable for existing equipment. Summary of the invention

DETAILED DESCRIPTION

[0043] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0044] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0045] like Figure 1 , Figure 3 , Figure 4 As shown, a cleaning-free fully automatic food production equipment, a thick granular food material taking device 2, an automatic material receiving device 7, a touch screen 5, and a main controller, the thick granular food material taking device 2 includes a pushing device 201, an extrusion plate 202, a loading box 203, and an extrusion bin 204, a plurality of loading boxes 203 are installed in the extrusion bin 204, the side wall of the extrusion bin 204 is provided with a feeding port 205, the side wall of the loading box 203 is provided with an opening, the output end of the pushing device 201 is connected to the extrusion plate 202, and the extrusion plate 202 is adapted to the opening of the loading box 203; the automatic material receiving device 7 is used to receive the food material lowered by the thick granular food material taking device 2, the touch screen 5 is used for the operator to perform human-computer interaction with the equipment, and the main controller is used to receive detection signals and send control signals.

[0046] In the thick slurry granular food material taking device, the pushing device can be connected to the extrusion bin to facilitate better adaptation of the extrusion plate and the loading box. The pushing device can adopt a slider-type screw push rod, and the pushing device drives the extrusion plate to push into the loading box to extrude the thick slurry granular material from the material bag. The discharge pipe of the material bag extends from the discharge port, so that the discharge position of the thick slurry granules can be customized and adjusted; when the operator selects the food preparation method on the touch screen, the main controller is electrically connected to the electrical components in the equipment, and the main controller receives data sent from the touch screen, generates a recipe by receiving the customer's DIY food ingredient data, converts it into a machine control signal, and sends a control signal to the thick slurry granular food material taking device to control the action of the pushing device to extrude the thick slurry granular food. A bowl dropping device can also be provided in the equipment to realize the function of automatically supplying a bowl.

[0047] like Figure 2 , Figure 5 , Figure 6 As shown, more specifically, it also includes a solid food material taking device 3 and a liquid food material taking device 1, the solid food material taking device 3 includes a barrel 301, a fixed bracket 303, a flexible impeller 3012, and an impeller driving mechanism 3036, the barrel 301 is detachably mounted on the fixed bracket 303, the flexible impeller 3012 is mounted inside the barrel 301, the impeller driving mechanism 3036 is fixed on the fixed bracket 303, and the impeller driving mechanism 3036 is used to provide kinetic energy for the flexible impeller 3012; the liquid food material taking device 1 includes a storage rack 102 and a peristaltic pump 101, and the peristaltic pump 101 is mounted on the storage rack 102.

[0048] like Fig.16 As shown, the impeller shaft of the flexible impeller has a gear that matches the impeller drive mechanism shaft, such as Fig.10 As shown, when the barrel is installed on the bracket, the impeller shaft of the flexible impeller is connected to the impeller driving mechanism shaft at the same time, so that the flexible impeller can be driven to rotate when the impeller driving mechanism rotates, so as to discharge solid food materials. The bottom of the barrel can be set to a funnel shape, which is convenient for the precise discharge of solid food materials and prevents the solid food materials from being spilled on the outside of the supporting bowl during the discharge process; when liquid food materials are taken, the liquid food material package with the discharge tube is placed on the storage rack, and the middle section of the discharge tube passes through the peristaltic pump; when the operator selects the food preparation method on the touch screen, the main controller receives the data sent by the touch screen, and can send a control signal to the solid food material taking device to control the impeller driving mechanism to drive the flexible impeller to rotate, so as to realize the real-time and precise discharge of solid food materials, and can also control the peristaltic pump to operate the liquid food material taking device to realize the real-time and precise discharge of liquid food materials.

[0049] like Figure 7As shown, in order to prevent the impeller from squeezing the soft granular material too much when discharging the material, thereby causing the material to be crushed, and to ensure the integrity of the food ingredient particles, a distribution piece structure can also be installed in the barrel. The distribution piece includes an upper distribution piece, a lower distribution piece, and a distribution shaft. The distribution piece structure is located on the top of the flexible impeller. The upper distribution piece is fixed in the barrel through the distribution shaft. It consists of an inclined straight edge and an arc-shaped lower edge, and has a symmetrical shape. The lower distribution piece consists of a lower left distribution piece and a lower right distribution piece. In actual use, as long as one of them can achieve its function, the lower distribution piece is fixed in the barrel with the upper distribution piece through the shaft, as shown in FIG. Figure 8 As shown, the upper and lower distribution pieces are combined together, and the blades of the flexible impeller are attached to the lower distribution piece, so that the solid ingredients in the barrel can enter the middle position of the barrel and mainly fall on the two blades in the middle of the impeller; the areas on both sides of the impeller close to the barrel wall will rarely accumulate solid ingredients; the arc length of the left and right lower distribution pieces just overlaps a little with the impeller, and the impeller rotates left or right, which will move the left or right lower distribution piece. The left or right lower distribution piece is suspended on the distribution piece shaft and is movable. It can rotate around the axis with a maximum amplitude of about 90 degrees, and its position is limited by the two pins on the lower distribution piece and the upper distribution piece; as shown in the figure, initially, there is no or very little solid ingredients in area A. When the impeller rotates counterclockwise, a blade will move the lower left distribution piece to rotate it upward by a certain angle, and the blade is an elastic body, so the blade will pass over the left distribution piece and rotate counterclockwise. Due to the obstruction of the distribution plate, only a small amount of solid particle ingredients enters area A. At this time, the solid particle ingredients in area A will not be squeezed by the blades, and will fall out smoothly from the bottom of the barrel; the impeller has an indefinite number of blades (should be more than 4 blades), 6 blades in the figure, so every 60 degrees of rotation, there will be a new blade to move the lower distribution plate to make it retreat, so that a small amount of solid particle ingredients enter area A. When no blade moves to the lower distribution plate, due to the weight, the lower distribution plate always rotates downward (around the axis), so that there is no or only a small amount of solid particle ingredients accumulated in area A; the above periodic interaction between the impeller blades and the distribution plate can make area A periodically enter a small amount of solid particle ingredients, thereby avoiding area A being filled with ingredients and being squeezed and crushed by the blades. Similarly, due to the symmetrical design, the working principle of area B is the same as that of area A; if the impeller moves in only one direction, only one lower distribution plate can meet the requirements.

[0050] like Fig. 9 As shown, more specifically, the fixed bracket 303 includes a rectangular frame 3034 and a limit frame, the impeller driving mechanism 3036 is arranged on the top outer walls on both sides of the rectangular frame 3034, a plurality of limit frames are horizontally arranged in the rectangular frame 3034, and a limit block 3011 is also arranged on the outer wall of one side of the barrel 301, and the barrel 301 is placed on the limit frame through the limit block 3011.

[0051] A U-shaped folding bracket of the same size as the edge of the rectangular frame can also be installed. When the barrel is long, the middle section of the barrel can be folded and fixed by the folding bracket. The distance between the limit frames can be set to be equivalent to the width of the barrel. When the barrel is inserted between the limit frames, the limit blocks on the side walls of the barrel can prevent the barrel from falling due to gravity, and enable the barrel to be taken out horizontally.

[0052] like Fig. 9 As shown, more specifically, the limit frame includes a limit beam, a pull ring 3032, and a spring pin 3035. The limit beam includes a horizontal beam 3033 and a vertical beam 3031. One side of the horizontal beam 3033 is connected to the top outer wall of one side of the vertical beam 3031. The pull ring 3032 and the spring pin 3035 are connected by a soft steel wire. The pull ring 3032 and the spring pin 3035 are both installed on the horizontal beam 3033, and the limit block 3011 is in contact with the horizontal beam 3033.

[0053] The limiting beam is generally in an inverted L-shaped structure. The arrangement of the crossbeam facilitates the placement of the limiting block and the installation of the pull ring and the spring pin. The crossbeam is provided with a pull ring hole for the pull ring to pass through and a spring hole for the spring pin to be installed. When the spring pin and the pull ring are installed, a part of the pull ring passes through the pull ring hole and extends from the outer wall of the top of the crossbeam, and the pin body of the spring pin also extends from the outer wall of the top of the crossbeam. Since the pull ring and the spring pin are connected by a soft steel wire, when the pull ring is pulled upward, the spring pin can move downward with the action of the soft steel wire, so that the barrel can move horizontally between the gaps of the limiting frame. When the barrel is placed between the gaps of the limiting frame, the pull ring is first pulled up so that the barrel can move smoothly on the limiting frame, so that the impeller shaft and the impeller drive mechanism shaft are connected, and then the pull ring is put down. At this time, the spring pin extends out and blocks the position of the limiting block, so that the barrel can no longer move horizontally on the limiting frame, thereby achieving a limiting and fixing effect on the barrel.

[0054] In addition, the barrels can be arranged in two rows, and the impeller axes of the two rows of barrels can be matched with the impeller drive mechanism axes set up on the edge of the rectangular frame, which can effectively utilize the spatial position of the equipment.

[0055] like Fig.10 As shown, more specifically, the automatic material receiving device 7 includes a polar coordinate robotic arm 8 and an anti-dropping tray 702. The anti-dropping tray 702 is installed at the bottom of the thick slurry particle food taking device 2, the solid food taking device 3, and the liquid food taking device 1. The polar coordinate robotic arm 8 is slidably connected to the anti-dropping tray 702.

[0056] like Fig.14As shown, more specifically, the polar coordinate robotic arm 8 includes a polar coordinate motion track 801 and a rotating robotic arm 802. A slide groove is provided on the anti-dropping tray 702. The polar coordinate motion track 801 is installed at the bottom of the anti-dropping tray 702. One end of the rotating robotic arm 802 passes through the slide groove and is connected to the polar coordinate motion track 801. The polar coordinate motion track 801 is arranged parallel to the slide groove. The rotation range of the rotating robotic arm 802 is the unloading range of the solid food taking device 3, the thick slurry particle food taking device 2, and the liquid food taking device 1.

[0057] The vertical axis of the rotating mechanical arm is connected with the polar coordinate motion track through the bearing seat. The polar coordinate motion track is used to drive the rotating mechanical arm to move on the horizontal plane. The driving part of the rotating mechanical arm is installed at the bottom of the anti-dropping tray together with the polar coordinate motion track. The rotating axis of the rotating mechanical arm extends out from the gap of the anti-dropping tray. A bracket for placing a bowl can be installed at one end of the rotating axis. The rotation range and rotation radius of the mechanical axis can be set according to actual operation needs, so that the rotation range of the rotating mechanical arm is within the unloading range of the solid food material taking device, the thick slurry particle food material taking device, and the liquid food material taking device, so that the rotating mechanical arm can smoothly receive the material. The polar coordinate motion track is used to determine the horizontal X-axis coordinate of the automatic material receiving device. The rotating mechanical arm is used to determine the angular coordinate θ of the automatic material receiving device. The angle and the X-axis coordinate (θ, X) can accurately send the bowl / cup tray to any position in the rectangular area below several food ingredient taking devices. A photoelectric sensor and a weighing sensor are installed on the horizontal arm of the rotating mechanical arm, and the cup / bowl tray is installed on the weighing sensor.

[0058] like Fig.15 As shown, the edge of the gap of the tray is at a 45° angle, and the rotating axis of the rotating robotic arm extends out from the gap. Pressure strips are provided on the edges of both sides of the gap, and a soft film is pressed under the pressure strips. The length of the soft film is sufficient to overlap, and the softness of the soft film can prevent the movement of the rotating axis from being hindered. The soft film can prevent fallen food from falling on the polar coordinate motion track set under the anti-dropping tray, and can slide down to the inside of the tray along the 45° angle, so as to facilitate subsequent collection and cleaning.

[0059] like Fig.12 As shown, more specifically, it also includes a tube clamp valve 6, which includes a power device 601, a roller 603, a pull pin 604, and a valve body 602. The pull pin 604 is used to connect the power device 601 and the valve body 602. A roller 603 is provided in the valve body 602. The output end of the power device 601 is fixedly connected to the roller 603. The tube clamp valve 6 is installed close to the thick slurry particle food material taking device 2.

[0060] As shown in Figure 13, the dotted line is a plastic hose that passes through the valve body and passes beside the roller. The clamp valve drive mechanism can make the roller arm rotate between 0 and 90 degrees. The working principle of the clamp valve is as follows:

[0061] (1) The clamp valve is closed: The roller arm is at 0 degrees, the roller completely squeezes the hose to the side wall of the valve body, the hose wall fits inside, and the gap is 0, indicating that the hose is completely blocked and the internal fluid cannot flow out.

[0062] (2) Fully open state of the hose clamp valve: When the roller arm is at 90 degrees, the hose is fully released and the internal fluid can flow out.

[0063] (3) Any angle state of the pipe clamp valve: In actual use, the opening size of the pipe clamp valve can be adjusted. Specifically, the maximum opening angle can be set in the main controller according to the requirements of fluid viscosity, particle size and other parameters. The main controller of the equipment controls the rotation of the pipe clamp valve drive mechanism to drive the roller arm so that the roller arm is in a suitable position between 0 and 90 degrees. The hose is an elastic body. In its natural state, the hose will bounce to a position blocked by the roller.

[0064] The valve body of the pipe clamp valve is connected to the power device through a pull pin. The power device can be a variable speed motor with gears. The output end of the motor is connected to the roller. When the motor rotates, it drives the roller to rotate, which can clamp and release the discharge pipe of the thick slurry particle bag, realizing the function of a fluid valve, but there is no need to worry about the cleaning problem of the fluid valve.

[0065] like Fig.11 As shown, more specifically, it also includes an automatic supply device 4, which includes a material barrel 403, a feeding tray 402, a pushing device 401, and a detection device. The pushing device 401 is vertically arranged in the material barrel 403, and the feeding tray 402 is arranged at the output end of the pushing device 401. The detection device is used to detect the distance between the material in the feeding tray 402 and the top inner wall of the material barrel 403.

[0066] Materials such as cup lids and spoons can be placed on the feeding tray. When a certain amount of material is taken out, the detection device detects that the distance between the material in the feeding tray and the inner wall of the top of the material barrel increases. If the detected distance increases to the set value range, the main controller controls the pushing device to push the feeding tray upward, so that the distance between the material and the inner wall of the top of the material barrel is shortened to within the set range, which can ensure that customers can conveniently take the materials in the feeding tray in real time.

[0067] A method for using a cleaning-free fully automatic food preparation device comprises the following steps:

[0068] Step 1: Place a concentrated granular material bag with a first discharge hose in a loading box, extend the first discharge hose out of the loading box through a discharge port, and use the roller in the tube clamp valve to clamp the middle section of the first hose; place a liquid material bag with a second discharge hose on a storage rack, and use a peristaltic pump to clamp the middle section of the second discharge hose; pour solid food into the barrel; place a receiving bowl on the rotating robotic arm.

[0069] Step 2: The main controller reads the human-machine data of the touch screen and sends a control signal to one or more of the pushing device, the impeller drive mechanism, the peristaltic pump, the pushing device, and the polar coordinate robot arm to complete the food production.

[0070] Solid food ingredients are loaded and unloaded as a whole in complete material barrel units. They will not be loaded directly on site. They are loaded and cleaned in the central kitchen as a whole. This ensures the efficiency of on-site loading and unloading, as well as the cleanliness of the environment inside the machine. After placing the thick slurry granular ingredients, solid ingredients and liquid ingredients, the customer operates through the touch screen.
