Problems solved by technology

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.

Embodiment 1

[0017] A kind of cleaning device in the seaweed processing process as shown in Figure 1, comprises that diameter is 2 meters, and height is the cleaning pool 1 of 6 meters and auxiliary cleaning pool 2, and the setting position of cleaning pool 1 is 2.2 meters higher than auxiliary cleaning pool 2 , a sewage outlet 4 is arranged at the bottom of the cleaning pool 1, a filter screen 3 is arranged at a distance of 60 cm from the bottom above the bottom of the cleaning pool 1, and a pool wall is surrounded between 70 cm to 1 meter above the bottom of the cleaning pool 1 8 micropore air inlets 5 are provided, and the micropore air inlet 5 is connected with an air pump (not shown in the figure), and an auxiliary sewage outlet 6 is arranged at the bottom of the auxiliary cleaning pool 2, and the distance above the bottom of the auxiliary cleaning pool 2 The bottom 60 centimeters place is provided with auxiliary filter net 7, is provided with dish discharge port 8 on the pool wall apa...

Embodiment 2

[0019] A kind of cleaning device in the laver processing process is basically the same as embodiment 1, the only difference is that a vegetable discharge port 8 is arranged at the end of the auxiliary cleaning pool 2 .

[0020] Water and impurity after washing will be removed by manpower or power if sewage outlet 4 or auxiliary sewage outlet 6 are not established.

[0021] Filter screen 3 or auxiliary filter screen 7 are located at near the bottom of the pond and are near better, because the impurity of laver is generally not a lot.

[0022] The quantity of micropore air inlet 5 and auxiliary micropore air inlet 9 is established according to the size of the pond, and it is better to be located at the lower position of the pond, so that the bubbling effect is better.

Embodiment 3

[0024] A cleaning method during laver processing, comprising the following steps: (1), closing the sewage outlet 4 and the valve 11, pumping 5 tons of clean seawater into the cleaning pool 1 with a water pump, and then adding the harvested surface water to drain the surface water 300 kilograms of fresh laver; (2), start the air pump of 300 W, just send air into seawater from microporous air inlet 5, make seawater bubble, thereby laver fluctuates in seawater, and bubbling 16 minutes, in laver Most of the impurities are blown down, and the impurities sink to the bottom of the pool through the filter screen 3, then turn off the air pump and let it stand for 5 minutes to silence the impurities; (3), close the auxiliary sewage outlet 6 and the vegetable discharge outlet 8, and open the water flow pipe 10 valve 11, the laver and part of the seawater in the cleaning tank 1 flow into the auxiliary cleaning tank 2, after all the laver flows in, close the valve 11 of the water flow pipel...

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...
