Description

Bag feeding type vacuum packaging machine with low energy consumption

Technical Field

The invention relates to the technical field of production, in particular to a low-energy-consumption bag feeding type vacuum packaging machine.

Background

The existing production process of the vacuum rice dumpling comprises the following steps: step 1, soaking dry rice in normal temperature water; step 2, putting the rice obtained in the step 1 on a conveyor belt of a rice draining machine for draining; step 3, mixing the drained rice obtained in the step 2 with seasonings; step 4, quantifying the seasoner rice obtained in the step 3 by a weighing method or a volume method; step 5, wrapping the quantitative seasoner rice obtained in the step 4 and corresponding stuffing together with the reed leaves, and bundling to obtain a raw rice dumpling; step 6, putting the raw rice dumplings obtained in the step 5 into a rice dumpling boiling pot through a filling machine, adding water which submerges the rice dumplings, covering and sealing, opening a steam valve and a pressure valve, controlling the temperature in the pot to be 100 ℃ and keeping the temperature for 30 minutes, and then closing the pressure valve to enable the temperature in the pot to rise to 121 ℃ and keep the temperature for 30 minutes; step 7, placing the cooked rice dumplings obtained in the step 6 into a rice dumpling cooling line for air cooling until the central temperature of the rice dumplings is reduced to 40 ℃; step 8, manually filling the cooled cooked rice dumplings obtained in the step 7 into rice dumpling cooking bags; step 9, putting the cooking bag filled with the rice dumplings obtained in the step 8 into a vacuum packaging machine for vacuum sealing; and 10, putting the vacuum raw rice dumplings obtained in the step 9 into a sterilizing pot, and keeping the central temperature of the rice dumplings at 121 ℃ for 15-20 minutes through high temperature and high pressure.

In terms of product quality, because the vacuum rice dumpling product needs to guarantee a quality guarantee period of 9 months at normal temperature, the existing vacuum rice dumpling production process needs to go through two high-temperature and high-pressure processing links, wherein one time is to finish a cooking process in a rice dumpling cooking pot through high temperature and high pressure, and the other time is to finish a sterilization process in a sterilization pot through high temperature and high pressure after vacuum packaging. The high temperature and high pressure of the secondary sterilization process have obvious influence on the internal tissue structure and flavor substances of the vacuum rice dumpling, and compared with the rice dumpling before sterilization, the color of the vacuum rice dumpling rice material and the taste of the meat stuffing are poorer.

On production efficiency, for guaranteeing cooked effect and sterilization effect, 90 minutes consuming the process of cooking in the current vacuum zongzi production process, 45 minutes consuming the cooling process, 60 minutes consuming the sterilization process, on the basis of guaranteeing current product quality, the time of above process can't compress, becomes the bottleneck that the productivity promoted, if will improve the productivity and can only through increasing production area and equipment investment.

In terms of energy consumption, the main water, electricity and steam energy consumption of the existing vacuum rice dumpling production process is in three links of cooking, cooling and sterilization. The cooking process is to soak the raw rice dumplings in water, and realize a high-temperature and high-pressure cooking environment through heat exchange between steam and water. In the cooking process, the reed leaves, the rice materials, the stuffing and the grease can exchange with the surrounding water, after cooking is finished, the cooking water contains a large amount of grease, the extract of the reed leaves, the starch substances in the rice materials and a plurality of seasonings, the whole pot of water needs to be discharged before cooking at one time, and after cleaning in the cooking pot is finished, water is added again for cooking. In the 90-minute link of cooking, steam is adopted for heat exchange in the whole process, air cooling is mainly adopted in the cooling process at present, air exhaust and air supply of a high-power fan are completed through electric power, and the central temperature of the rice dumpling is reduced within 45 minutes.

In the manual work, in the existing vacuum rice dumpling production process, the rice dumpling wrapping process is mainly used, and more manpower is occupied by vacuum. The number of workers in a busy season of each year also becomes a big factor influencing productivity and increasing cost along with the increase of labor cost and the increase of labor difficulty.

Therefore, the vacuum rice dumpling of the production process for making the rice dumpling cooked while sterilizing is designed by the applicant, so that only one-time heating is needed when the vacuum rice dumpling is made. The prior bag-feeding type vacuum packaging machine used in the manufacturing process of the vacuum rice dumpling by one-time heating has the following defects: the water quantity of the boiled rice dumplings for making the rice dumplings by one-time new heating is vacuumized after adding water according to the requirement when the rice dumplings are soaked to a set value (namely, water is absorbed to a set quantity), so that the water quantity is inaccurate easily, and the water quantity lost by vacuumizing in different seasonal temperature environments is different; when the weight deviation of the materials in each link is towards the same direction, the weight of the final finished rice dumpling is not in accordance with the requirement; the bag of cooking is for levelly and smoothly wrapping up in the zongzi outside and because the bag wall thickness of cooking is very thin to lead to the bag of cooking to promote the effect poor to the resistance to compression of zongzi.
