Description

Technical Field

[0001] This utility model relates to the field of strawberry freeze-drying technology, specifically to a raw material sorting machine for strawberry freeze-drying processing. Background Technology

[0002] Freeze-dried strawberries are a healthy snack made using freeze-drying technology. The principle involves rapidly freezing fresh strawberries at low temperatures (e.g., -30℃ to -40℃), then removing the internal ice crystals directly through sublimation in a vacuum environment, ultimately preserving the strawberry's complete natural shape, vibrant color, and rich aroma. This process maximizes the retention of nutrients (such as vitamin C and anthocyanins), while creating a loose, porous, and crisp texture. It requires no additives, making it easy to preserve for a long time and meeting modern consumers' demands for natural, nutritious, and convenient products. Raw material sorting machines are the core equipment at the front end of food processing production lines. They use integrated optical sensors, high-speed cameras, and precision airflow nozzles to automatically detect and grade materials. According to a patent published on the China Patent Network, the patent title is: "A Diamond Raw Material Sorting Machine," patent application number: 202121447211.1. It includes a collection box. A motor is welded and fixed to the left side of the front of the collection box via a bracket. A sliding groove is formed in the center of the front of the collection box. A limit block is welded and fixed to the outside of the sliding groove on the front of the collection box. A drive rod is slidably connected inside the limit block. A crushing box is welded and fixed to the upper surface of the collection box. A high-temperature box is welded and fixed to the center of the upper surface of the crushing box. A hydraulic actuator is welded and fixed to the outer side of the upper surface of the crushing box. The hydraulic actuator is welded and fixed via a hydraulic rod. The machine has a lower pressure plate with a crushing device on its bottom surface. A guide plate is welded and fixed to the inner wall of the crushing box below the lower pressure plate. A sorting device is installed inside the collection box. The crushing device can crush the diamond raw material, and the sorting device can sort the crushed raw material for easy use. However, during the sorting process, some strawberries may be too soft and break when squeezed. The juice that flows out is sticky and will adhere to the slide and baffle, sticking to other strawberries and quickly forming a blockage. This affects the smooth flow of material and makes it difficult to guarantee the subsequent processing progress.

[0003] Therefore, it is necessary to redesign and modify the raw material sorting machine to effectively prevent material discharge blockage. Utility Model Content

[0031] The working principle and usage process of this utility model are as follows: First, the user starts the motor 6, which drives the cam 7 to rotate continuously. The rotational motion of the cam 7 is converted into the up-and-down reciprocating motion of the wheel rod 8 and the horizontal plate 9 in contact with it. The horizontal plate 9 is guided in the vertical groove 25 by two sliding rods 10, which drives the pressure plate 11 to press down stably. The pressure plate 11 periodically presses down on the impact rod 13 at the top of the connecting plate 12. Combined with the rebound force of the spring 14, the impact rod 13 rhythmically impacts and vibrates the discharge inclined plate 3. The high-frequency, intermittent vibration of the discharge inclined plate 3 effectively prevents wet or slightly large strawberries from slipping on the inclined plate. To prevent adhesion and blockage, and ensure smooth discharge, vibration can be used to shake off the blocked raw materials. Then, while driving the cam 7, the motor 6 also drives the reciprocating screw 17 to rotate. Under the constraint of the slide plate 20 and the slide groove 23, the reciprocating sleeve 19 converts the rotational motion of the reciprocating screw 17 into its own linear reciprocating motion. The reciprocating sleeve 19 drives the crank plate 21 and the blower 22 at its bottom to move back and forth on the top of the drum sorting assembly 2. During the movement, the blower 22 sucks up light impurities such as dust attached to the surface of the drum and overflow to a specific position, so as to avoid dust overflow.

[0032] In summary, this raw material sorting machine for freeze-drying strawberries changes the traditional problem of easy clogging during material feeding. By using a strike bar 13 to impact the discharge inclined plate 3, the machine can shake the raw materials off, increasing the smoothness of material feeding and ensuring the progress of subsequent processing.
