Description

Technical Field

[0001] This utility model relates to the field of pre-prepared food production technology, specifically a blanching machine for producing pre-prepared food. Background Technology

[0002] Pre-prepared meals, also known as ready-made foods, generally refer to semi-finished products made from various agricultural, livestock, poultry, and aquatic products as raw materials, combined with seasonings and other auxiliary ingredients (including food additives), and processed through pre-selection and preparation techniques. These semi-finished products typically require storage or transportation under cold chain conditions, and are intended for consumption by consumers or food service providers after simple heating or cooking. Pre-prepared meals come in a wide variety of styles, with relatively complex raw materials, and require high standards for ingredient freshness and storage conditions. Blanching is a crucial pre-treatment step in the production of pre-prepared meals to remove impurities, microorganisms, and some enzymes from the surface of the food, while preserving its color and texture.

[0003] In existing technologies, blanching of vegetables is generally done using a heating tank. This requires heating the water inside the tank to a certain temperature, then placing the vegetables into the tank, letting them sit for a period of time, and then removing them to complete the blanching process. However, existing devices cannot quickly remove a large amount of water from the surface of the vegetables after blanching, which is not conducive to subsequent processing. Therefore, it is necessary to propose a blanching machine for producing pre-prepared vegetables to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a blanching machine for producing pre-cooked vegetables, which has the feature of quickly draining a large amount of water from the surface of the vegetables after blanching, thus facilitating subsequent processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a blanching machine for producing pre-cooked vegetables, comprising a base, a heating box disposed above the base, a rotating column rotatably connected to the bottom side of the inner wall of the heating box, a motor mounted at the lower end of the base, the output end of the motor passing through the lower end face of the base and the heating box and fixedly connected to the rotating column, a square groove being formed on the upper end face of the rotating column, a matching square block being disposed inside the square groove, a guide block being fixedly connected to the lower end of the square block, a placement cylinder being fixedly connected to the upper end of the square block, a retaining seat being fixedly connected to the inner wall of the heating box, and a plurality of evenly distributed ball bearings in contact with the outer wall of the placement cylinder being mounted on the inner wall of the retaining seat;

[0006] The outer wall of the placement cylinder is slidably connected to a fixing ring located above the retaining seat via a slide rail, and locking mechanisms are provided on the left and right sides of the outer wall of the fixing ring.

[0007] To facilitate fixing and releasing the fixing ring, in a preferred embodiment of the blanching machine for producing pre-prepared vegetables according to this utility model, the locking mechanism includes two U-shaped frames fixedly connected to the upper end of the retaining seat and located on the left and right sides of the fixing ring. The left and right sides of the fixing ring are respectively fixedly connected with screws passing through the interior of the two U-shaped frames, and the outer walls of the two screws are threaded with hexagonal nuts that abut against the opposite side of the two U-shaped frames.

[0008] To facilitate the installation of the heating wire and the heating of the water inside the heating box, in a preferred embodiment of the blanching machine for producing pre-cooked vegetables according to this utility model, a cavity is provided between the inner and outer walls of the heating box, and the heating wire is installed inside the cavity.

[0009] To prevent the two hexagonal nuts from detaching from the outer walls of the two screws, in a preferred embodiment of the blanching machine for producing pre-prepared vegetables according to this utility model, a limiting disc is fixedly connected to the opposite sides of the two screws.

[0010] In order to facilitate the drainage of water inside the heating box, as a preferred embodiment of the blanching machine for producing pre-cooked dishes according to this utility model, the lower end of the heating box is connected to an L-shaped drain valve pipe.

[0011] To facilitate the support and fixation of the heating box, in a preferred embodiment of the blanching machine for producing pre-prepared vegetables according to this utility model, a fixing rod that is fixedly connected to the base is fixedly connected to each of the four corners of the lower end face of the heating box.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] After blanching the vegetables, the hot water is drained from the heating tank. The motor then drives the rotating column to rotate, which in turn drives the placement cylinder to rotate along the slide rail. Since the position of the fixing ring remains unchanged, it prevents the placement cylinder from moving upward. The multiple ball bearings reduce the friction when the placement cylinder rotates. The centrifugal force generated when the placement cylinder rotates can shake off excess water from the vegetables, thus facilitating subsequent processing. Attached Figure Description

[0020] Please see Figures 1 to 5 A blanching machine for producing pre-cooked vegetables includes a base 1, a heating box 2 is arranged above the base 1, a rotating column 4 is rotatably connected to the bottom side of the inner wall of the heating box 2, a motor 3 is installed at the lower end of the base 1, the output end of the motor 3 passes through the lower end face of the base 1 and the heating box 2 and is fixedly connected to the rotating column 4, a square groove 5 is opened on the upper end face of the rotating column 4, a matching square block 6 is arranged inside the square groove 5, a guide block is fixedly connected to the lower end of the square block 6, a placement cylinder 7 is fixedly connected to the upper end of the square block 6, a retaining seat 8 is fixedly connected to the inner wall of the heating box 2, and a plurality of evenly distributed ball bearings 9 are installed on the inner wall of the retaining seat 8 and contact the outer wall of the placement cylinder 7.

[0021] The outer wall of the placement cylinder 7 is slidably connected to a fixing ring 11 located above the retaining seat 8 via a slide rail 10. Locking mechanisms are provided on the left and right sides of the outer wall of the fixing ring 11.

[0022] In this embodiment: during use, the bottom side of the placement cylinder 7 passes through the interior of the retaining seat 8 and enters the interior of the heating box 2. Subsequently, the square block 6 enters the interior of the square groove 5 under the guidance of the guide block. Since they match each other, the square block 6 and the rotating column 4 can be prevented from rotating relative to each other. At this time, multiple balls 9 contact the outer wall of the placement cylinder 7, thereby maintaining the position of the placement cylinder 7. At the same time, the two screws 13 enter the interior of the two U-shaped frames 12 respectively, and the fixing ring 11 is fixed by the locking mechanism, thereby preventing the fixing ring 11 from moving upward and preventing the position of the placement cylinder 7 from moving upward, thus completing the installation of the placement cylinder 7.

[0023] Water is then added to a certain height inside the heating box 2 and heated. After heating, a certain amount of vegetables is added to the placement cylinder 7 and left to stand for a period of time to blanch the vegetables. The hot water is then discharged from the heating box 2 and driven by the motor 3 to rotate the rotating column 4. Due to the limiting effect of the square block 6 and the square groove 5, the placement cylinder 7 rotates with the slide rail 10. Since the position of the fixing ring 11 is fixed, the placement cylinder 7 is prevented from moving upward. The friction of the placement cylinder 7 during rotation is reduced by the setting of multiple ball bearings 9. The centrifugal force of the placement cylinder 7 during rotation can shake off the excess water from the vegetables and discharge it from the heating box 2, thus facilitating subsequent processing.

[0024] After the food is drained, the locking mechanism releases the fixing ring 11, allowing the placement cylinder 7 and the food inside to be removed.

[0025] As a technical optimization of this utility model, the locking mechanism includes two U-shaped frames 12 fixedly connected to the upper end of the retaining seat 8 and located on the left and right sides of the fixing ring 11. The left and right sides of the fixing ring 11 are respectively fixedly connected with screws 13 passing through the interior of the two U-shaped frames 12. The outer walls of the two screws 13 are threaded with hexagonal nuts 14 that abut against the opposite side of the two U-shaped frames 12.

[0026] In this embodiment: when it is necessary to fix the fixing ring 11, the two hexagonal nuts 14 are rotated by a wrench, so that they can move relative to each other on the outer wall of the two screws 13 until the two hexagonal nuts 14 are tightly abutted against the opposite sides of the two U-shaped frames 12, thus completing the fixing of the fixing ring 11.

[0027] To release the fixing of the retaining ring 11, turn the two hexagonal nuts 14 with a wrench and move them in opposite directions until they separate from the two U-shaped brackets 12, thus releasing the fixing of the retaining ring 11.

[0028] As a technical optimization of this utility model, a cavity 15 is provided between the inner wall and the outer wall of the heating box 2, and an electric heating wire 16 is installed inside the cavity 15.

[0029] In this embodiment: a cavity 15 is provided to facilitate the installation of the heating wire 16, and the heating wire 16 is provided to heat the water inside the heating box 2.

[0030] As a technical optimization of this utility model, a limiting disc is fixedly connected to the opposite side of each of the two screws 13.

[0031] In this embodiment, by setting two limiting discs, the two hexagonal nuts 14 can be prevented from detaching from the outer walls of the two screws 13 respectively.

[0032] As a technical optimization of this utility model, an L-shaped drain valve pipe 18 is connected through the lower end of the heating box 2.

[0033] In this embodiment, an L-shaped drain valve pipe 18 is provided to facilitate the drainage of water from inside the heating box 2.

[0034] As a technical optimization of this utility model, fixing rods 17 that are fixedly connected to the base 1 are fixedly connected to the four corners of the lower end face of the heating box 2.

[0035] In this embodiment, four fixing rods 17 are provided to support and fix the heating box 2.

[0036] Working principle: In use, firstly, the bottom side of the placement cylinder 7 passes through the inside of the retaining seat 8 and enters the inside of the heating box 2. Then, the square block 6 enters the inside of the square groove 5 under the guidance of the guide block. Since they match each other, the square block 6 and the rotating column 4 can be prevented from rotating relative to each other. At this time, multiple balls 9 contact the outer wall of the placement cylinder 7, thereby maintaining the position of the placement cylinder 7. At the same time, the two screws 13 enter the inside of the two U-shaped frames 12 respectively. Then, the two hexagonal nuts 14 are turned by the wrench, so that they can move relative to each other on the outer wall of the two screws 13 until the two hexagonal nuts 14 are tightly abutted against the opposite side of the two U-shaped frames 12, thereby preventing the fixing ring 11 from moving upward and preventing the position of the placement cylinder 7 from moving upward, thus completing the installation of the placement cylinder 7.

[0037] Water is added to a certain height inside the heating box 2 and heated by the heating wire 16. After heating, a certain amount of vegetables are added to the placement cylinder 7 and left to stand for a period of time to blanch the vegetables. Water is then drained from the heating box 2 through the L-shaped drain valve pipe 18. The motor 3 drives the rotating column 4 to rotate. Due to the limiting effect of the square block 6 and the square groove 5, the placement cylinder 7 rotates with the slide rail 10. Since the position of the fixing ring 11 is fixed, the placement cylinder 7 is prevented from moving upward. The multiple ball bearings 9 reduce the friction when the placement cylinder 7 rotates. The centrifugal force when the placement cylinder 7 rotates can shake off the excess water from the vegetables and drain it from the heating box 2 through the L-shaped drain valve pipe 18, thus facilitating subsequent processing.

[0038] After the vegetables are drained, turn the two hexagonal nuts 14 with a wrench and move them in opposite directions until they separate from the two U-shaped brackets 12, thereby releasing the fixing state of the fixing ring 11, so that the placement tube 7 along with the vegetables inside can be taken out.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
