Description

Technical Field

[0001] The invention relates to the technical field of carotene preparation and extraction, in particular to a highly efficient carotene preparation and extraction device. Background Art

[0002] Carrots contain a lot of beta-carotene, which can be converted into vitamin A after being ingested by the human digestive organs. It can maintain the health of eyes and skin, improve night blindness and rough skin, and help the body protect against free radical damage. Carotene is very important to the human body, so it is necessary to extract carotene during processing. The extraction process requires multiple steps such as raw material extraction, filtration and drying, and multiple devices are required during processing.

[0003] When extracting carotene, it is necessary to mix the extracting solution and the carrot pieces, precipitate the carotene in the carrots through the extracting solution, and then separate the carotene and the extracting solution to obtain the carotene. For example, "the invention patent application with the publication number CN214158605U discloses a carotene extraction device for salt algae", and the carotene and the extracting device are mixed and stirred by improving the stirring device to improve the precipitation efficiency. However, this method of improving the precipitation efficiency by improving the stirring method has limited improvement. In addition, "the invention patent application with the publication number CN217489940U discloses a filtering device for carotene extraction with a filter residue treatment function", and the mixed and stirred solution is filtered through the filtering device, and then the filter residue is cleaned. This filtering method realizes solid-liquid separation by its own gravity, and it takes a long time to wait for the liquid to flow down, and it takes a long time, and some of the solution in the filtered filter residue does not flow down, so it is wasteful to directly treat it.

[0014] Working principle: the chopped carrot pieces and the prepared extract are transported to the heating boiler through the feed pipe, and then the inner wall of the heating boiler is heated, and then the first motor is started to drive the stirring rod to rotate, thereby driving the second scraper, the stirring blade and the first scraper to rotate. At the same time, the condensed water is filled into the interior of the cooling facility through the water inlet pipe arranged on the cooling facility and then flows out through the water outlet pipe. After that, the extract in the heating boiler is heated and evaporated, floats to the top of the heating boiler, and then condenses into liquid. It is scraped by the first scraper and falls back to the bottom of the heating boiler to participate in precipitation. When the precipitation is completed, the second motor is started, and the second motor drives the worm to rotate. At this time, the second spring is in a contracted state and has elastic force. The rotation of the worm drives the rotation of the first worm wheel. The rotation of the first worm wheel drives the first screw to move, and then drives the gate to move to open the pipeline. At this time, the first spring is in a contracted state and a smooth round rod is arranged on the surface of the first screw and at the position of the first spring and the other end opposite to it. The first worm wheel is located on the smooth round rod at the position of the first spring. The solid-liquid mixture in the heating boiler falls from the pipeline to the inclined plate, and the liquid therein passes through the holes arranged on the push plate. The filter residue is then moved by the second motor, and the third motor starts to drive the third screw to rotate, and the third motor starts to drive the third screw to rotate, and the filter residue is moved by the second motor, and the third motor starts to drive the third screw to rotate, and the filter residue is moved by the second motor, and the third screw moves to the upper limit of the fixed rod, and the push plate moves along the inclined plate under the limit of the fixed rod. When the push plate moves to the highest point on the left end of the inclined plate, it fits with the extrusion plate to extrude the filter residue. The push plate continues to move and drives the extrusion plate to move backward. When the roller reaches the inclined surface set on the inclined surface block, the second motor stops and the push plate stops moving. At the same time, the third motor starts to drive the third screw to rotate, and the third screw moves to the upper limit of the limit slide rod. The filter residue is then pushed to the impurity outlet and leaves the main body, and the filter residue is then processed. The liquid outlet is a drawer-type pull-out setting, which can be pulled out to clean the residue on it. After completion, the pushing device rotates in the opposite direction to return to its original position. At the same time, the second motor rotates in the opposite direction to drive the gate plate to move into the pipeline to close the channel of the pipeline. At the same time, the first worm gear is located on another round rod on the first screw rod, and at the same time drives the pushing plate back to its original position.

[0015] (III) Beneficial effects

[0016] The present invention provides an efficient carotene preparation and extraction device, which has the following beneficial effects:

[0017] 1. The solid-liquid mixture in the heating boiler is heated by arranging a heating boiler and a cooling facility to improve the carotene precipitation efficiency. The heated and evaporated precipitate contacts the top of the heating boiler and is condensed into liquid under the action of the cooling facility. The precipitate is scraped off by a first scraper to maintain the concentration of the precipitate in the heating boiler and the carotene precipitation efficiency.

[0018] 2. After the precipitation is completed, the gate is removed by setting a stirring device and the push plate is pushed at the same time. The precipitated liquid flows to the impurity outlet through the holes set on the inclined plate and the push plate and is collected below the impurity outlet. The precipitated residue is moved to the extrusion plate by pushing the push plate to squeeze out part of the liquid remaining in the residue, thereby reducing waste.

[0019] 3. The extruded impurities are pushed out through the set pushing device to prevent the accumulation of impurities and affect the filtering efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
