Description

TECHNICAL FIELD

[0001] The application belongs to the field of tomato production equipment, and in particular to a tomato squeezing device. BACKGROUND

[0002] Tomatoes are delicious and nutritious, and their consumption is increasing, which has led to an increase in various industrial processing products. Industrial production requires the use of mechanical equipment for assistance, and most tomato products require the tomatoes to be processed into tomato juice first. Tomato juice production requires a squeezing device. Current squeezing devices squeeze juice by pressure, and industrial use often involves a conveyor belt. These two squeezing methods have certain usage defects for tomatoes. For example, the current belt conveyor lacks cleaning during operation, which affects subsequent squeezing work due to residual materials. Tomatoes naturally contain juice, not just other squeezed materials, and the existing squeezing machine can cause the natural juice of tomatoes to leak and be wasted.

[0003] For example, patent CN202020833817.8 is a typical belt squeezing machine that squeezes juice from the squeezed material by extruding it with two conveyor belts and uses a scraper to remove the residual squeezing material on the conveyor belt. However, for tomatoes that naturally contain juice, not just the flesh, this method cannot solve the problem of juice leakage and waste during feeding. Moreover, the scraper cannot completely remove the residual material on the conveyor belt, which can affect the squeezing effect over time and cause the squeezed material to deteriorate in hot weather. Therefore, a squeezing device that overcomes the above problems is needed. SUMMARY

[0004] The present application provides a tomato squeezing device that improves the squeezing effect of materials, avoids waste, and improves the quality of squeezing, especially for tomatoes. The technical problem to be solved is the waste of juice and the retention of residual materials during the current tomato squeezing process.

[0005] The technical solution adopted by the present application is as follows:

[0006] A tomato squeezing device, comprising an upper extrusion device and a lower extrusion device, the upper extrusion device comprising an upper filter belt and an extrusion roller, and the lower extrusion device comprising a lower filter belt and an extrusion roller, the upper filter belt being wrapped around part of the extrusion roller outside and forming a closed structure, the lower filter belt being wrapped around part of the extrusion roller outside and forming a closed structure, the lower surface of the upper filter belt and the upper surface of the lower filter belt being matched, and the extrusion roller forming an S shape at the matched part of the upper filter belt and the lower filter belt.

[0007] The feeding plate and the stirring roller are arranged above the lower filter belt, and the extrusion roller is provided with a liquid outlet groove below the matching part of the upper filter belt and the lower filter belt.

[0008] Further, the adjusting mechanism is connected with the rack, and the adjusting mechanism comprises a slide, a hydraulic cylinder, a piston rod and a sliding block.

[0009] Further, the upper cleaning head and the upper drying head are arranged above the upper filter belt, the upper drying head is arranged behind the upper cleaning head along the conveying direction of the upper filter belt, the upper cleaning groove is arranged below the upper part of the upper filter belt, and the upper drain pipe is arranged on the upper cleaning groove.

[0010] Further, the lower cleaning head and the lower drying head are arranged above the lower filter belt, the lower drying head is arranged behind the lower cleaning head along the conveying direction of the lower filter belt, the lower cleaning groove is arranged below the lower part of the lower filter belt, and the lower drain pipe is arranged on the lower cleaning groove.

[0011] Further, the upper filter belt is provided with the upper scraper at the discharging end, and the lower filter belt is provided with the lower scraper at the discharging end.

[0012] Further, the upper filter belt and the lower filter belt are both concave in the middle part, the feeding plate is an arc-shaped plate, the arc-shaped plate of the feeding plate matches the arc-shaped structure of the upper filter belt and the lower filter belt, and the middle part of the extrusion roller is arc-shaped, and the arc-shaped structure of the middle part of the extrusion roller matches the arc-shaped structure of the upper filter belt and the lower filter belt.

[0013] Further, the arc-shaped structure of the middle part of the extrusion roller is concave or convex, and the concave arc-shaped structure and the convex arc-shaped structure of the extrusion roller have the same radian.

[0014] Further, the stirring blade is arranged on the outer wall of the stirring roller, the stirring blade is an arc-shaped blade, and the grid plate is arranged on the blade of the stirring blade.

[0015] Further, the pressing plate is arranged behind the stirring roller above the upper filter belt, and the pressing plate is connected with the upper cleaning groove through the telescopic rod.

[0016] Further, the feeding plate is an arc-shaped plate, the pressing plate is an arc-shaped plate, and the radian of the feeding plate and the pressing plate is the same as the radian of the upper filter belt or the lower filter belt.

[0017] After the above structure is adopted, the following beneficial effects are achieved.

[0018] 1. By using a feeding plate to concentrate the material and prevent it from falling, and by using a mixing roller to spread the material evenly, the problem of uneven accumulation of material in existing pressing equipment, which affects the quality and efficiency of pressing, is overcome. This results in a more uniform distribution of material, which can better and more evenly press the moisture in the material, making the tomato pressing more thorough and ensuring the pressing quality.

[0019] 2. By using curved upper and lower filter belts to concentrate the juice from the tomatoes, the problem of juice dripping and being wasted during the pressing process of existing pressing equipment is overcome. This allows the juice to be concentrated on the upper and lower filter belts and drain quickly, avoiding spillage.

[0020] 3. Due to the adoption of an S-shaped structure to tension and compress the joint between the upper and lower filter belts, the multi-stage pressing using the S-shaped structure overcomes the problems of incomplete pressing and the filter belt itself absorbing some juice in existing pressing methods. This makes the tomato pressing more thorough, and the pressed juice will concentrate in the lower protruding part of the S-shape, reducing the amount of juice absorbed by the filter belt itself, resulting in better pressing effect.

[0021] 4. By using an upper cleaning head to clean the upper filter belt and a lower cleaning head to clean the lower filter belt, and by using upper and lower drying heads to quickly dry both filter belts, the problem of easy clogging of existing filter belts after pressing is overcome. This allows for quick cleaning of the filter mesh after pressing and rapid unblocking and drying of the mesh using drying airflow, effectively avoiding the problem of filter belt clogging caused by a large amount of pressing work.

[0022] 5. By using upper and lower scrapers to scrape off residual materials, the problem of material sticking to the filter belt and causing incomplete pressing in subsequent work is overcome, thus quickly removing the residue after pressing and improving work quality. Attached Figure Description
