Cleaning device used in laver processing course and its cleaning method

Abstract

The invention discloses a cleaning equipment and a cleaning method in the process of processing the dried purple seaseed, which comprises a cleaning pool and an auxiliary cleaning pool which has the same volume with the cleaning pool; the cleaning pool and the auxiliary cleaning pool are arranged in a high-low shape; the cleaning pool is communicated with the auxiliary cleaning pool through a water pipeline; the inlet of the water pipeline is arranged at the position nearby the bottom of the cleaning pool; the outlet of the water pipeline is arranged at the position nearby the central section of the auxiliary cleaning pool; the level of the outlet of the water pipeline is lower than that of the inlet of the water pipeline; a valve is positioned at the water pipeline; a plurality of microporous inlets are arranged around the wall of the cleaning pool; a plurality of auxiliary microporous inlets are positioned around the wall of the auxiliary pool. The invention has the advantages that: the design is reasonable; the structure is simple; the integrity of the form of the dried purple seaseed can be kept with a less loss; the energy consumption can be reduced; in addition, the EDTA-Na salt is added in the process of cleaning, thereby the heavy metal content of the dried purple seaseed can be lowered greatly.

Description

technical field [0001] The invention relates to laver processing, in particular to a cleaning device and a cleaning method in the laver processing process. Background technique [0002] Seaweed is a kind of algae cultivated artificially, which has high commercial value and is a kind of green food. Since laver is naturally cultivated and grows in the ocean, there are impurities such as mud and sand in the harvested laver. Therefore, in the laver processing process, the laver must first be cleaned. The traditional laver cleaning method is: use manpower to wash the laver in the ocean or a pool filled with seawater to wash away the impurities in the laver, which requires more manpower and time, and the cleaning benefit is not high, and whether it is cleaned is related to It is related to human factors, and it is often not easy to clean; currently, in the industrial laver processing, a special cleaning device is used to clean the laver. The cleaning device includes a cleaning po...

The traditional laver cleaning method is: use manpower to wash the laver in the ocean or a pool filled with seawater to wash away the impurities in the laver, which requires more manpower and time, and the cleaning benefit is not high, and whether it is cleaned is related to It is related to human factors, and it is often not easy to clean; currently, in the industrial laver processing, a special cleaning device is used to clean the laver. The cleaning device includes a cleaning pool, and an electric mixer is arranged in the cleaning pool. The bottom of the cleaning tank is provided with a sewage outlet. The cleaning method is to put an appropriate amount of laver into the cleaning tank filled with seawater or the mixed water of seawater and fresh water, start the mixer, and use the agitation of the laver to separate the impurities in the laver from the laver, and the impurities will sink into the At the bottom of the pool, to achieve the purpose of cleaning impurities, after stirring, the laver is pumped to the next processing procedure for further processing, and then the sewage outlet is opened, and the impurities are discharged out of the pool; in order to clean the impurities in the laver, it is often necessary to change the water Clean it again, or transfer the laver to another cleaning device and clean it again. Utilize the above-mentioned cleaning device to clean the laver, although the manpower has been reduced and the cleaning efficiency has been improved, but in the stirring process, the laver is easily entangled and broken by the mixer. It has brought difficulties, and also caused damage to the form of laver and business loss of laver, reducing the quality of processed laver

In addition, seaweed contains heavy metal elements that are harmful to the human body. For example, the Pb content of seaweed is generally 0.05-0.50 mg / kg (in dry weight). Long-term consumption of seaweed with high heavy metal content will cause heavy metal poisoning.
