Embodiment Construction

[0011] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0012] The sauerkraut fresh-keeping and deodorizing device consists of a fermentation tank 1, which also includes a delivery pump 2, a solid-liquid separator 3, a mixer 4 and an ozone generator 5, a fermentation tank and a delivery pump, a delivery pump and a solid-liquid separator, and a solid-liquid separator. The separator is connected with the mixer, the mixer and the ozone generator through pipelines, and the outlet of the mixer is connected with the fermenter through pipelines. A flow meter 6 is connected between the delivery pump and the solid-liquid separator. The liquid outlet of the fermenter is located at the bottom of the tank, and the inlet connected to the mixer is located at the top. The mixer is a single-pipe mixer, and a one-way control valve is arranged between the ozone generator and the mixer.

Abstract

The present invention provides one kind of pickle preserving and deodorizing apparatus, which includes a fermenting tank, a conveying pump, a solid-liquid separator, a mixer and an ozone generator connected successively through pipeline, with the outlet of the mixer being connected through pipeline to the fermenting tank. The apparatus has the ozone generator and the fermenting tank well combined, so that it can sterilize pickle and water simultaneously after fermentation in the fermentation system and before packing, reduce microbial contamination and prolong the preservation period while maintaining the flavor of pickle. The apparatus of the present invention has simple structure, and is suitable for scale development of pickle industry.

Description
