Description

Technical Field

[0001] This utility model relates to the technical field of pigment extraction devices, specifically a fruit and vegetable pigment extraction device. Background Technology

[0002] Many natural fruits and vegetables have their own color, which can stimulate appetite and increase the secretion of digestive juices, thus aiding digestion and absorption. This color is an important sensory indicator of food. However, natural foods are prone to fading or discoloration during processing and preservation. To improve the color of food, people often add food coloring during processing to enhance its sensory properties.

[0003] When extracting pigments from fruits and vegetables, the process involves cutting and crushing the fruits and vegetables, adding an extraction solvent (such as ethanol, acetone, methanol, ethyl acetate, etc.) for extraction, and finally filtering out impurities and concentrating and drying the extract. In practice, the cutting and crushing processes consume a significant amount of time, which is detrimental to efficient production. Therefore, we propose a fruit and vegetable pigment extraction device. Utility Model Content

[0004] The purpose of this invention is to provide a fruit and vegetable pigment extraction device. By setting a feeding cylinder with staggered internal cutting blades on the side of the extraction tank, the fruits and vegetables are squeezed and cut into pieces by the internal cutting blades when they are added through the feeding cylinder. Then they fall into the extraction tank. While the stirring rod rotates and stirs, the side cutting blades further chop the fruits and vegetables. There is no need to chop and crush the fruits and vegetables before extraction, which is conducive to efficient production and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fruit and vegetable pigment extraction device, comprising an extraction tank and a rotating rod. The rotating rod is vertically rotatably installed inside the extraction tank and is connected to a motor mounted on the top surface of the extraction tank. Multiple stirring rods are horizontally fixed on the side of the rotating rod, and a side cutter is fixed on the side of each stirring rod. A feeding cylinder is fixed inside the upper side of the extraction tank, with its upper part communicating with the outside and its bottom communicating with the inside of the extraction tank. Multiple internal cutters are staggered and fixed at the lower inside of the feeding cylinder, with the cutting edges of the internal cutters facing upwards. A horizontal plate is supported on the surface of the extraction tank above the feeding cylinder by a support rod. An electric push rod is vertically installed in the middle of the plate, and a pressure plate is fixed at the bottom end of the electric push rod, positioned directly above the feeding cylinder. The diameter of the pressure plate is smaller than the inner diameter of the feeding cylinder.

[0006] By adopting the above technical solution, the fruits and vegetables to be extracted are placed in the feeding cylinder, pressed down by the pressure plate and cut into pieces by the inner cutter before entering the extraction tank. Then, the extraction liquid is added, and the stirring rod rotates to use the side cutter to chop the fruits and vegetables and stir them, which can efficiently extract pigments from fruits and vegetables.

[0007] Optionally, the feed cylinder is installed above the side of the extraction tank via a detachable structure, so that the inner cutting blade can be disassembled along with the feed cylinder.

[0008] By adopting the above technical solution, the feed cylinder containing internal cutting blades of different densities can be replaced, making it suitable for fruits and vegetables with different cutting requirements.

[0009] Optionally, the detachable structure consists of a ring block surrounding the outer ring above the feed cylinder and an insertion port on the upper surface of the extraction tank, with the feed cylinder inserted into the insertion port and the ring block supporting the surface of the extraction tank above the insertion port.

[0010] By adopting the above technical solution, the feed cylinder can be directly removed by lifting the ring block.

[0011] Optionally, a liquid addition pipe is provided on the upper side of the extraction tank, and the liquid addition pipe is connected to the interior of the extraction tank.

[0012] By adopting the above technical solution, solutions such as extractants can be added into the extraction tank through the addition pipe.

[0013] Optionally, a discharge pipe is connected to the bottom center of the extraction tank, and the discharge pipe communicates with the inside of the extraction tank.

[0014] By adopting the above technical solution, after extraction is completed, the solution, extractant, fruits and vegetables, etc. can be discharged from the discharge pipe.

[0015] Optionally, the rotating rod can be driven by a motor to rotate clockwise, and the side cutter is located on the side of the stirring rod in the direction of rotation.

[0016] By adopting the above technical solution, it is ensured that the side cutter can chop fruits and vegetables when the stirring rod rotates.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] 1. The technical solution of this application is to set a feeding cylinder with staggered internal cutting blades on the side of the extraction tank. When fruits and vegetables are added through the feeding cylinder, they are squeezed and cut into pieces by the internal cutting blades. Then they fall into the extraction tank. While the stirring rod rotates and stirs, the side cutting blades on the side will further chop the fruits and vegetables. There is no need to chop and crush the fruits and vegetables before extraction, which is conducive to efficient production.

[0019] 2. The technical solution of this application makes the feeding cylinder and the internal cutting blade detachable, so that the feeding cylinder containing internal cutting blades of different densities can be replaced according to the different types of fruits and vegetables being extracted.
