Description

Technical Field

[0001] The utility model relates to the technical field of tomato sauce processing, in particular to a screening device used for tomato sauce processing. Background Art

[0002] Processing tomatoes are a group of tomato varieties suitable for making raw materials for tomato products. They have thin skin, thick flesh, less juice, and high soluble solids content. The skin residue after sauce is mainly composed of tomato seeds and tomato skins, of which tomato seeds contain about 25% oil and 20% protein. Tomato skin is a good source of dietary fiber and rich in lycopene. The pressing process of tomato seed oil and the extraction process of lycopene are relatively mature. The market prospects for deep-processed products of tomato seeds and skins are promising. However, most of the skin residue after sauce is dried and used as fertilizer or feed. Only a small amount of skin residue is separated manually to produce tomato seeds, which has low production efficiency and high labor intensity. The skin residue that is not removed in time is discarded, which wastes resources and pollutes the environment.

[0003] After searching, the publication number CN107983664A discloses a tomato seed separation device after tomato paste processing, which belongs to the technical field of food processing machinery. The device of the present invention transports the processed tomato paste from the feed pipe to the stirring tank, and the motor drives the stirrer to stir the tomato paste through the rotating shaft. After stirring for a period of time, the stirring device on the rack moves, and the laser sensor scans the surface of the tomato paste. Since the color of the tomato seeds is gray and the color of the tomato paste is red, the laser sensor identifies the tomato seeds by color and locates them. Then, the control system drives the horizontal walking device and the vertical walking device to move the adsorption device to the position above the tomato seeds. The tomato seeds are adsorbed by the adsorption device and transmitted to the tomato seed collector through the hose. All the tomato seeds on the belt surface are adsorbed, and the stirrer continues to stir. The adsorption device repeats the work until there are no more tomato seeds in the tomato paste, and the tomato paste is transported through the discharge pipe.

[0004] However, in the above scheme, the tomato seeds in the tomato paste need to be completely adsorbed before they can be transported, and the screening of the tomato seeds and tomato skins takes a long time, resulting in a large amount of time being wasted in the screening process of the tomato paste, thereby affecting the processing efficiency of the tomato paste.

[0005] To this end, we proposed a screening equipment for tomato sauce processing to solve the above drawbacks. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The utility model adopts a stirrer, a containing box, a filter hopper, an inclined plate, an L-shaped frame, and a filter screen to form a tomato paste screening mechanism. By injecting tomato paste into a feed hopper, the tomato paste is caused to slide from the inclined plate into a containing space formed by the L-shaped frame and the inner wall of the screening box under the action of gravity and a pneumatic hammer. The tomato paste is stirred by the impeller of the stirrer, so that the tomato paste passes through the filter screen and enters the containing box, and is filtered twice by the filter hopper, so that the tomato seeds and tomato skins in the tomato paste are separated, thereby achieving the purpose of improving the quality of the tomato paste and recycling the tomato seeds and tomato skins. Compared with the existing screening equipment, the tomato paste can be transported without waiting for the impurities to be completely separated, so as to continuously screen the tomato paste, thereby improving the screening processing rate of the tomato paste.

[0016] (2) The utility model adopts a maintenance opening, a guide rail, a storage box, a guide wheel, and a limit block to form a moving mechanism for the storage box. By pulling the storage box in the maintenance opening, the guide wheel at the bottom of the storage box rolls on the inner side of the guide rail, so that the storage box passes through the maintenance opening and extends to the outside of the screening box. At this time, the limit block arranged at the end of the guide rail away from the screening box can limit the guide wheel to prevent the storage box from falling off, so as to achieve the purpose of facilitating the cleaning of the storage box, and has good practicality.
