Blanching is one of the important operating units prior to many other processing techniques, such as filling, freezing, dewatering, etc. The enzymatic activity of fresh vegetables affects undesirable color and flavor that may be increased during processing and storage. Generally, fresh vegetables cannot be stored for a long period of time, even under freezing conditions, and most vegetables require a short heat treatment to inactivate enzymes carried by the fresh vegetables themselves, thereby preserving their organoleptic and nutritional qualities.

At present, various vegetable blanching devices exist in the prior art, but the blanching devices have complex structures and slightly poor blanching effect.

Firstly, referring to the Chinese patent with the application number of 201921495261X and the invention name of a spiral blanching machine capable of continuously and stably feeding, the invention discloses a spiral blanching machine capable of continuously and stably feeding, which comprises a shell and a conveyor belt, wherein a roller is fixedly connected to the bottom of the left side of an inner cavity of the shell, the right end of the roller penetrates through the shell and extends to the outside of the shell, the bottom of the left side of the shell is fixedly connected with a first motor, the right end of a rotating shaft of the first motor sequentially penetrates through the shell and the roller and extends to the inner cavity of the roller and is fixedly connected with a rotating rod, the surface of the rotating rod is fixedly connected with a spiral blade, and the inner wall of the shell is fixedly connected with a transverse plate. The spiral blanching machine adopts the conveying belt to continuously supply materials, but because the water in the roller can continuously flow outwards, the vegetables can not be completely soaked in blanching water in the roller, so that blanching is uneven and the effect is poor.

Secondly, referring to the Chinese patent with the application number of 2019224958699 and the invention name of an intelligent temperature control type blanching machine, the invention discloses an intelligent temperature control type blanching machine, which comprises a shell, wherein a carrying belt is arranged in the shell, and the carrying belt comprises a horizontal section and an inclined section connected with the two ends of the horizontal section; the carrying belt is provided with baffle plates at uniform intervals; a reticular press belt is arranged above the carrying belt, and the lower surface of the press belt is in contact with the partition plate; be provided with steam nozzle between the upper and lower surface of pressing the area, carry and be provided with temperature sensor below the belt horizontal segment, steam nozzle and temperature sensor quantity are a plurality of, and even interval sets up. When blanching, the vegetables are completely immersed in hot water by adopting a structure that the carrying belt is matched with the pressing belt, the device has a complex structure, and the vegetable leaves are easy to adhere to the pressing belt and are inconvenient to use.

Therefore, the existing blanching machine is complex in structure and inconvenient to use, water cannot be kept at a relatively stable temperature, blanching water cannot be recycled due to the fact that impurities in the water are not easy to treat, and water resources and heat energy are wasted. Impurities on the blanched vegetables cannot be cleaned synchronously, so that the quality of the dried vegetables in the next step is influenced.

the flow direction of the blanching water and the flow direction of the vegetables are in a reverse structure, and the blanching water has 3 functions: 1. the blanching water temperature at the feed end of the conveying cylinder 1 is low, and the blanching water temperature at the part close to the lifting cylinder 6 is high, so that a preheating section and a blanching section are formed in the conveying cylinder 1, vegetables are gradually heated and blanched, and the blanching effect is improved; 2. the vegetable leaves are not easy to be attached to the spiral conveying blade 3; 3. can increase the detention time of vegetables in the conveying cylinder 1 and improve the blanching effect of the vegetables.

Two, this float boiling hot equipment forms preheating section, floats boiling hot section, washes section and waterlogging caused by excessive rainfall section in proper order to the discharge end that promotes the cleaning part by the feed end that floats boiling hot conveying part, floats boiling hot section after scalding vegetables, can also wash, improves the cleanliness factor of vegetables to the waterlogging caused by excessive rainfall section can carry out the waterlogging caused by excessive rainfall to vegetables, avoids a large amount of boiling hot rivers to go out, saves the resource.

Three, this float boiling hot device can make and float boiling hot water level line 5 and be higher than transport cylinder 1 all the time, and vegetables are constantly carried to promotion washing part through helical conveying blade 3 in getting into transport cylinder 1 from feeder hopper 11, and these vegetables are soaked in completely in the boiling hot water in transport cylinder 1, and vegetables in transport cylinder 1 have obtained stirring from top to bottom at the auger delivery in-process, have improved the homogeneity that floats boiling hot.

The circulating water impurity removal box 22 can remove impurities from the blanching water, impurities with large specific gravity entering the box body 22a sink and precipitate at the bottom of the box body, so that the impurities can be discharged, the impurities with small specific gravity float on the water surface in the box body 22a, and the floating objects can be discharged through the foam discharge port 22 d; and the surface of the cylinder body of the filter cylinder 22b of the impurity removing box forms a cone-shaped water inlet hole 22b1 structure with uneven height, the cone-shaped water inlet hole 22b1 reduces the adhesion area of impurities and weakens the adhesion force of the impurities, the impurities on the cone-shaped water inlet hole 22b1 are removed from the cone-shaped water inlet hole 22b1 under the flowing action of water in the box, the water inlet of the filter cylinder 22b is not influenced, and the blanching water with the impurities removed can be recycled.

And fifthly, the blanching water circulating device is also provided with a heating device 19 on a water delivery pipe 21, so that the temperature of blanching water in the conveying cylinder 1 can be kept.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
