Description

Technical Field

[0001] The utility model relates to the field of sealing machines, in particular to a rice vacuum sealing machine. Background Art

[0002] As a staple food in our daily lives, rice storage conditions are crucial to maintaining its freshness and quality. Traditional packaging methods often fail to effectively isolate air, moisture, and microorganisms, making rice susceptible to moisture, mold, and deterioration during storage, affecting its edible value and safety.

[0003] With the development of science and technology, vacuum packaging technology has become one of the important means of food preservation because it can effectively remove oxygen from the package, reduce the survival rate of microorganisms, and delay the oxidation process of food. In the field of rice packaging, the application of vacuum sealing machines has gradually gained attention. However, the existing rice vacuum sealing machines still have some technical deficiencies. For example, conventional vacuum packaging machines only complete the vacuum packaging of rice by putting rice into a vacuum bag and heat-sealing the bag opening under a vacuum environment. The defects of this vacuum packaging method are: the rice is granular, and a large amount of rice is vacuum-packed in a scattered state, resulting in uneven distribution of rice grains in the vacuum bag and an uneven outer surface of the vacuum bag. A lot of space is wasted during storage, transportation, and placement. Under the same space, the storage capacity is greatly reduced, which invisibly increases the cost; there is a technology in the prior art that can solve the problem of uneven surface of the vacuum bag mentioned above, such as a rice brick vibrator mentioned in the Chinese patent with application number CN202011042006.7, but it requires manual vacuum bag loading into the mold, capping the cavity opening, extending the bag opening part from the capping slot, and detaching the vacuum bag from the mold. Multiple steps are required to obtain vacuum-packaged rice with a fixed shape and a smooth outer surface. The excessive number of steps required to complete a bag of rice increased the time required to package it. Furthermore, the delicate process of inserting and removing the vacuum bag from the mold required considerable operator effort, further reducing packaging efficiency. Furthermore, the volume of vacuum bags for different kilograms of rice varied, necessitating custom mold specifications, further increasing costs. Utility Model Content

[0036] Before starting the machine, unfasten the buckles around the vacuum cover 2 and the machine 1, open the vacuum cover 2, and then place the unsealed vacuum bag containing rice flat on the vibration plate 11, and need to place it between the two shaping plates 73.

The electric heating pipe 32 starts heating after the vacuum pump 41 stops, causing the vacuum bag opening to be heat-melted and sealed. The electric heating pipe 32 operates for 4 seconds. At this time, the vacuum packaging and heat-pressing sealing steps are completed. After the electric heating pipe 32 stops operating, the electric pressure relief valve 43 converts the negative pressure in the sealed space to normal pressure. The buckle is unlocked, the vacuum cover 2 is opened, and the processed vacuum bag containing rice can be removed. The electric pressure relief valve 43 is also set with a safety pressure value. When the safety pressure value is reached, the electric pressure relief valve 43 will forcibly release the pressure to ensure the safety of personnel and equipment.
