Description

Technical Field

[0001] The invention relates to the technical field of drying, and in particular to a fluid interactive multi-temperature section static high-efficiency drying process for dried Gongcai and cucumber. Background Art

[0002] Gongcai and dried cucumbers, popular dehydrated vegetables, hold a significant market share thanks to their unique flavor, rich nutrition, and ease of storage and transportation. Market demand for these vegetables continues to grow year by year. However, drying is a critical step in their processing, impacting both product quality and production efficiency. Traditional drying processes have numerous drawbacks, hindering the market's demand for high-quality dried gongcai and cucumbers. Specifically, these issues include:

[0003] Strip-shaped issues: Traditional drying processes can easily damage the strips of dried gongcai and cucumber due to external forces such as tumbling and squeezing. For example, in traditional drum drying, the material is constantly tumbling within the drum, which can easily break and bend the long strips of gongcai and cucumber, resulting in a large number of broken and short strips, seriously affecting the appearance and commercial value of the product.

[0004] Color and taste issues: Traditional processes lack precise temperature control and often fail to adjust appropriately to the dehydration rate of the product at different stages, affecting the color and taste of the product. For example, if the drying temperature is too high and the drying time is too long, Gongcai and dried cucumbers will easily turn brown and lose their original bright color. At the same time, overdrying will cause the product to lose its original crisp texture and become dry, hard, and rough. If the temperature is too low, the drying time will be prolonged, which may cause the product to mold and deteriorate, affecting its nutritional content and taste.

[0005] Drying uniformity issues: For densely stacked materials, the traditional drying process's relatively simple air blowing method makes it difficult to ensure uniform heating of the materials from top to bottom, resulting in uneven drying. For example, when using a single upward air blowing drying method, the materials on the upper layer of the tray may be completely dried, while the materials on the lower layer still contain a lot of moisture. This can lead to large differences in the dryness and moisture content of the same batch of products. Some materials may deteriorate due to excessive moisture, while others may be over-dried and affect quality.

[0006] Based on the above, a dry fluid interactive multi-temperature section static high-efficiency drying process for Gongcai and cucumber is invented. Summary of the Invention

[0032] Example 1:

[0033] The present invention provides a fluid interactive multi-temperature section static high-efficiency drying process for dried Gongcai and cucumber, which comprises the following specific steps:

[0034] S1, peeling and stripping: the fresh Gongcai material is peeled by a vegetable peeling machine or manually (fresh cucumber does not require this operation), and the Gongcai or cucumber fresh material after removing the skin is cut into long strips of uniform size by machine / manually to obtain Gongcai / cucumber fresh strips;

[0035] S2, washing: washing with clean water to remove residues or foreign matter left on the surface of the Gongcai / cucumber strips during the stripping process; wherein the soaking time is set to 0.5 h; and the raw materials of the aqueous solution include, by weight: 10 parts of clean water, 0.3 parts of calcium chloride, 1 part of sodium chloride, and 0.1 parts of citric acid;

[0036] Calcium chloride: By combining with pectin in the cell wall of the material, it enhances the stability of the cell structure and improves the crispness effect;

[0037] Sodium chloride: uses osmotic pressure to promote the exudation of water from the material cells, accelerates the pre-dehydration process, and inhibits the growth of microorganisms;

[0038] Citric acid: adjusts the pH of the solution to weak acidity (pH 5.0-6.0), inhibits the activity of polyphenol oxidase, prevents browning of the material, and maintains bright color;

[0039] S3, pre-dehydration: placing the washed Gongcai / cucumber strips into a soaking tank and adding an aqueous solution for soaking to perform pre-dehydration and crispness preservation;

[0040] S4, Infrared Non-destructive Testing and Grading: Use infrared spectrometer to test pre-dehydrated Gongcai / cucumber strips to analyze their internal moisture distribution and fiber structure. Materials are then classified into different grades based on the test results. Materials of the same grade have similar dehydration characteristics, facilitating precise matching of subsequent drying process parameters.

[0041] S5, placing the materials on a plate: drain the graded Gongcai / cucumber strips and place them on a plate, making sure to maintain the shape of the Gongcai / cucumber strips during the placing process; the height of the material on the plate is set to 4-6 cm to ensure that the material height is uniform throughout the plate;

[0043] S7, medium-temperature drying: After the high-temperature section is completed, due to the decrease in the dehydration rate of the material, in order to avoid the problem of inconsistent material inside and outside caused by rapid dehydration at high temperature, medium-temperature drying is adopted to match the material dehydration rate; the material statically enters the medium-temperature drying section of the tunnel-type AD drying line for drying; the temperature of the medium-temperature drying section is set to 60-75 degrees, and the passing time of the medium-temperature drying section is set to 2-3 hours; in addition, the medium-temperature drying section of the tunnel-type AD drying line is set with 7-11 temperature zones from high to low.

[0044] S8, Microwave-assisted shaping: After drying at medium temperature, the material is sent to the microwave treatment chamber and treated with low-power microwaves. Microwaves can penetrate the interior of the material, evenly distributing residual moisture, while quickly shaping the fiber structure of the material, reducing morphological changes during the subsequent softening process. The power range is set to 200W, and the treatment time is set to 30 seconds.

[0045] S9, softening and collecting: After microwave shaping, the material enters the high-temperature and high-pressure softening bin, where high-pressure steam is used to quickly soften the material and control the moisture content. At the same time, the softened material is easy to manually collect and collect, reducing the material loss caused by over-drying and brittleness. The high-pressure steam time is set to 10 seconds, and the moisture content is controlled at 15%.
