Recently, the author saw a report that “Seaweed ushered in the spring harvest of the powerful fishermen in the harvest season. I was reminded of the taste of the sea, I knew it, and the ad song of the auspicious Sambo” was discovered. The advertisement of seaweed has long been one of the indelible impressions of the past years.
The display of the seaweed advertising screen is quite beautiful, but the production process of the early seaweed is not so easy. Seaweed is processed from Porphyra yezoensis. In areas where food machinery and equipment are not popular enough, picking seaweed is a livelihood that depends on the sea. Keep a close eye on the weather forecast, because if the seaweed is harvested, it cannot be dried in time. Then all the seaweed must be scrapped. In addition, it must catch the tide and start to pick the seaweed. When the seaweed is immersed in sea water, , Water grass and other debris only a lot more, so need to wash three or four times before drying. After drying is completed by the nori manufacturers for further processing, the production process is usually salt burning, sauce burning, frying and so on.
With the increasing popularity of food machinery and equipment, various production processes of Nori are gradually replaced by mechanical equipment. In the harvest of seaweed, nori harvesters and seaweed pickers have emerged. Seaweed Harvester consists of Power Machinery, Harvester, Harvester Shelf The collection box consists of four parts. The harvester is installed on the bow of the ship. During the advance of the hull, the shipkeeper arranges to pick up the laver and slowly pulls the steel pipe along the bow to the ship. The harvester rotates at this time and is cut. The laver can fall into the collection box. On the basis of the harvester, people developed the laver picking machine. The picking machine adopts the high-speed rotary cutting process and is suitable for the pole with the door bracket in the lower part of the semi-floating beach laver culture net. Full-season seaweed picking and tidal flattening of low-season seaweed picking can be done without picking and without damaging the root system of laver.
In the preliminary processing of seaweed, cleaning is an extremely important step. Because seaweed is mixed with two distinct substances: sediment and aquatic plants, it is necessary to separate the seaweed from the two. The general vegetable cleaning equipment is equipped with a bubble generating device so that The material is in a rolling state. This method can remove sediments very well. In addition, the kelp laver robot washing machine produced by Zhucheng Longxiang Industrial and Trade Co., Ltd. is advanced by manipulator-assisted laver, taking into account the characteristics of the laver's slender shape that does not easily advance. The overflow filtration device can filter floating impurities. However, these effects on aquatic weeds are not obvious enough. Therefore, we need to equip weeds to filter weeds. Afterwards, seaweed goes through the vegetable cutting machine and is purified and then enters the seaweed production line for slicing. Water, drying and other steps, and then sub-container packaging equipment, complete the initial processing.
After the initial processing, the storage of seaweed is also a big problem. In the traditional impression, dry matter is always easy to store, but both the dry seaweed and roasted seaweed are very demanding on the temperature and humidity. The temperature is too high, the air If the humidity is too high, the microorganisms in the laver will grow, the seaweed will deteriorate, and the original quality and nutritional value of the laver will be destroyed. As a result, some intelligent cold stores appear on the market, and the temperature and humidity of the seaweed can be adjusted to suit the storage of the laver. It is understood that The seaweed stored in the cold storage can extend the shelf life by eight to ten times. In addition, the low temperature storage can change the biological properties of the seaweed fiber, so that the taste of the seaweed is more delicious and the color is more attractive.
Nori is used to transform nori seaweed into a nori production line. Noriaceous seaweed has long since appeared a long time ago. There are also relatively large seaweed companies on the market. As a result, most of the new companies are manufacturing equipment, innovative taste, and stylish packaging efforts, and strive to open up. The new Blue Ocean. This makes most of the current production companies choose to introduce the production of seaweed production lines in countries such as Japan and Thailand. In 2016 alone, Jinjiang City introduced nearly ten international Noriland production lines. These foreignly introduced production lines can be used for production. Thai-style seaweed rolls, sandwiched seaweed, Korean-style seaweed, etc. Although our country has also developed a corresponding seaweed production line, according to entrepreneurs, foreign production lines are twice as expensive, but their efficiency is more than doubled. Therefore, comprehensively, the cost performance of foreign production lines is higher.
It can be seen that although China's seaweed industry has achieved mechanization, the equipment is still in the low-end stage and cannot compete with foreign equipment. In order to change this situation, China's food machinery and equipment enterprises need to increase research and innovation in related equipment. Strengthen, improve equipment performance to win the favor of the market.
