Description

Technical Field

[0001] The invention relates to the technical field of food processing, in particular to a double-sided spraying seasoning device for rice crust and a spraying seasoning method thereof. Background Art

[0002] Rice crust is a layer of rice grains that stick to the pot and become coked into blocks when cooking rice. The main ingredients are rice, millet, soybeans, corn flour, etc. It has the effect of thickening the stomach and aiding digestion. With the rapid development of modern food processing technology, rice crust has been developed into a delicious snack that can be preserved for a long time and is loved by people.

[0003] At present, in order to further meet the taste preferences of different groups of people, researchers in related fields have developed a spray seasoning device for processing rice crust raw materials, striving to develop more different flavors. However, the spray seasoning devices currently used are mostly single-sided operations. If you want to achieve the double-sided seasoning effect of the rice crust, you need to reciprocate the rice crust raw materials twice, which will also lead to a decrease in the processing efficiency of the overall device and an increase in the use and processing costs. Secondly, the two reciprocating processes are not conducive to streamlined production line operations and can only be achieved under ideal conditions or with more manual participation. The technical defects are very obvious. Summary of the invention
